Did Strategic Bombing in the Second World War Lead to ‘German Angst’? A Large-scale Empirical Test Across 89 German Cities. Martin Obschonka et al. European Journal of Personality, May/June 2017, Pages 234–257, http://onlinelibrary.wiley.com/doi/10.1002/per.2104/full
Abstract: A widespread stereotype holds that the Germans are notorious worriers, an idea captured by the term German angst. An analysis of country-level neurotic personality traits (trait anxiety, trait depression, and trait neuroticism; N = 7 210 276) across 109 countries provided mixed support for this idea; Germany ranked 20th, 31st, and 53rd for depression, anxiety, and neuroticism, respectively, suggesting, at best, the national stereotype is only partly valid. Theories put forward to explain the stereotypical characterization of Germany focus on the collective traumatic events experienced by Germany during World War II (WWII), such as the massive strategic bombing of German cities. We thus examined the link between strategic bombing of 89 German cities and today's regional levels in neurotic traits (N = 33 534) and related mental health problems. Contrary to the WWII bombing hypothesis, we found negative effects of strategic bombing on regional trait depression and mental health problems. This finding was robust when controlling for a host of economic factors and social structure. We also found Resilience × Stressor interactions: Cities with more severe bombings show more resilience today (lower levels of neurotic traits and mental health problems in the face of a current major stressor—economic hardship).

Understanding Cultural Persistence and Change
Understanding Cultural Persistence and Change. Paola Giuliano & Nathan Nunn. NBER Working Paper, July 2017. https://scholar.harvard.edu/nunn/publications/understanding-cultural-persistence-and-change
Abstract: When does culture persist and when does it change? We examine a determinant that has been put forth in the anthropology literature: the variability of the environment from one generation to the next. A prediction, which emerges from a class of existing models from evolutionary anthropology, is that following the customs of the previous generation is relatively more beneficial in stable environments where the culture that has evolved up to the previous generation is more likely to be relevant for the subsequent generation. We test this hypothesis by measuring the variability of average temperature across 20-year generations from 500–1900. Looking across countries, ethnic groups, and the descendants of immigrants, we find that populations with ancestors who lived in environments with more stability from one generation to the next place a greater importance in maintaining tradition today. These populations also exhibit more persistence in their traditions over time.

Cultures differ in the ability to enhance affective neural responses
Cultures differ in the ability to enhance affective neural responses. Michael Varnum & Ryan Hampton. Social Neuroscience, September/October 2017, Pages 594-603, www.tandfonline.com/doi/abs/10.1080/17470919.2016.1209239
Abstract: The present study (N = 55) used an event-related potential paradigm to investigate whether cultures differ in the ability to upregulate affective responses. Using stimuli selected from the International Affective Picture System, we found that European-Americans (N = 29) enhanced central-parietal late positive potential (LPP) (400–800 ms post-stimulus) responses to affective stimuli when instructed to do so, whereas East Asians (N = 26) did not. We observed cultural differences in the ability to enhance central-parietal LPP responses for both positively and negatively valenced stimuli, and the ability to enhance these two types of responses was positively correlated for Americans but negatively for East Asians. These results are consistent with the notion that cultural variations in norms and values regarding affective expression and experiences shape how the brain regulates emotions.

Gender: An Historical Perspective
Gender: An Historical Perspective. Paola Giuliano. NBER Working Paper No. 23635
NBER Program: POL. http://www.nber.org/papers/w23635
To explore this hypothesis, Giuliano (2015) looks at the correlation between historical plough use and whether the dowry is the most prevalent mode of marriage, whether the inheritance rule in a society is matrilineal, and if polygamy is prevalent5. She finds that in societies that used the plough, (a) inheritance rules appear to be less favorable to women—as indicated by the fact that matrilineality is less common, (b) there is less polygamy, and (c) a dowry is paid by the bride’s family. After establishing a correlation for the past, the author shows that differences in agricultural technology have a persistent effect on social norms, lasting until today. [...] she finds that societies that historically used the plough are characterized by higher parental authority granted to the father, by inheritance rules that favor male heirs, and by less freedom for women to move outside the house. She also finds that, in these societies, women are more likely to wear a veil in public.

Reflection Increases Costly (but Not Uncostly) Charitable Giving
Giving, Fast and Slow: Reflection Increases Costly (but Not Uncostly) Charitable Giving. Kellen Mrkva. Journal of Behavioral Decision Making, http://onlinelibrary.wiley.com/doi/10.1002/bdm.2023/abstract
Abstract: Are people intuitively generous or stingy? Does reflection make people more willing to give generous amounts to charity? Findings across the literature are mixed, with many studies finding no clear relationship between reflection and charitable giving (e.g., Hauge, Brekke, Johansson, Johansson-Stenman, & Svedsäter, 2016; Tinghög et al., 2016), while others find that reflection negatively affects giving (e.g., Small, Loewenstein, & Slovic, 2007), and still others find that reflection is positively associated with giving (e.g., Lohse, Goeschl, & Diederich, 2014). I demonstrate that reflection consistently increases costly giving to charity. In Study 1, people were initially reluctant to give costly amounts of money to charity, but those who reflected about the decision were more willing to give. In Studies 2–3, I isolated the role of costly stakes by randomly assigning people to either an uncostly donation ($0.40) or costly donation condition (e.g., $100), and randomly assigning them to decide under time pressure or after reflecting. Reflection increased their willingness to give costly amounts, but did not influence their willingness to give uncostly amounts. Similarly, the relationship between decision time and giving was positive when the stakes were costly but was relatively flat when the stakes were uncostly (Study 4)

A Chinese Threat to Australian Openness. By Merriden Varrall
A Chinese Threat to Australian Openness. By Merriden Varrall
https://www.nytimes.com/2017/07/31/opinion/australia-chinese-students.html
The New York Times, July 31, 2017
SYDNEY, Australia — Australians are increasingly concerned about China’s growing influence in the country. Chinese money is being funneled to politicians. Beijing-run media outlets buy ads in Australian newspapers to promote the Communist Party view on local and regional issues. Chinese companies are buying Australian farms and natural resources.
The push extends to Australia’s universities. Chinese agents are said to monitor Chinese students and report on those who fail to toe the Communist Party line. And in another troubling trend, many of the 150,000 visiting Chinese students are importing a pro-Beijing approach to the classroom that is stifling debate and openness.
In 2008-9 I taught international relations to undergraduates at a Chinese university in Beijing, giving me a window into Chinese students’ attitudes and behavior. I was struck by the tendency for students to align themselves with the government view.
I was not given any guidance or warnings about the topics I could cover in the classroom. But throughout the year, I was offered hints that my approach to teaching was inappropriate. Those warnings came not only from the administration but from the students themselves.
On several occasions, students suggested I use a different style of teaching. They found critical analysis and picking apart expert opinion uncomfortable. This was particularly true for readings and class discussions that could be construed as critical of China.
Most students, for example, would reject anything that suggested China had not always been peaceful. The majority of students would react angrily to any reading material implying that Japan was not an inherently aggressive and expansionist country.
Some students told me in private that they were afraid to express their views in class. They feared that their peers would report on them and that they would receive a black mark on their record. The minority of students who showed interest in open discussion were shut down by classmates who parroted Beijing’s talking points.
In one session, students gave a presentation that, unsurprisingly, painted the Japanese in a negative light. One of their classmates wondered aloud whether Chinese people still needed to hate Japan. Another suggested that China also publishes textbooks with self-serving interpretations of history, as Japan does. Outrage erupted. One student furiously accused the two of “not loving China enough.”
At my midyear review, I was told firmly by my department leadership that my approach of “trying to teach through rumor and hearsay” was unsuitable. When I refused to change my methods, I was told that I would not receive my bonus and that my contract would not be renewed.
Chinese students are taking this approach into the Australian classroom.
A recent ABC-Fairfax report gave the example of Lupin Lu, head of the Chinese Students and Scholars Association chapter at the University of Canberra. Ms. Lu said she would not hesitate to inform officials at the Chinese Embassy if she heard of Chinese students organizing, for example, protests against Beijing.
Even here in Australia, Chinese students have said they fear speaking up in class because they worry their compatriots will report them to embassy authorities. Some students ask to be placed in tutorial groups without other Chinese citizens so they can speak openly.
Sally Sargeson, an associate professor at the Australian National University, said to Forbes magazine that every Chinese student she asked about this problem “said they know they are being monitored and adjust their speech so they will not get into trouble.”
When Chinese students self-censor or monitor and report on their peers, it is not necessarily because the Chinese state is bearing down on them. Rather, many Chinese students believe that speaking out against the officially approved view, on any topic, is inappropriate. The anthropologist Erika Evasdottir describes this as “self-directed control.” Monitoring and reporting on peers who diverge from the party line is seen as the right thing to do.
Universities have not adequately addressed this threat to debate and openness. Officials may be reluctant to take action because overseas students bring a lot of money to underfunded Australian universities.
Because many Chinese students have internalized the need to align with official views, maintaining Australia’s standards for free and open debate will remain a daunting challenge. Australian universities could start by facing up to the problem.

Statehood experience, legal traditions, and climate change policies
Ang, J. B. and Fredriksson, P. G. (2017), Statehood experience, legal traditions, and climate change policies. Economic Inquiry, 55: 1511–1537. doi:10.1111/ecin.12441
Abstract: This study investigates how the implementation of modern climate change policies is related to former colonies' length of state history and their legal heritage. We argue that countries with longer statehood experience around the time of colonization were better equipped to implement the legal philosophies transplanted by their colonial powers. Therefore, the implications of receiving British common law versus French civil law should be particularly important in countries with a greater accumulated history of statehood. Using a cross-section of up to 78 former colonies, our results provide support for this hypothesis. In particular, our estimates demonstrate that common law countries have weaker modern climate change policies than civil law countries and the difference is inflated by a longer statehood experience, measured by the length of state history from 1 to 1800 AD. Legal origin has no effect in areas which, by the time of colonization, had no statehood experience. Finally, we report similar results for the pattern of labor market regulations. (JEL K15, K31, K32, O44, Q54, Q58)

The Helping Behavior Helps Lighten Physical Burden
The Helping Behavior Helps Lighten Physical Burden. Xilin Li and Xiaofei Xie. Basic and Applied Social Psychology, http://www.tandfonline.com/doi/abs/10.1080/01973533.2017.1320762
Abstract: It is often believed that helping behaviors benefit the recipients at the expense of the performers. However, we propose that costly helping behaviors could alleviate feelings of physical burden experienced by the performers. In support of the proposal, we found in five studies that both imaginary and real helping behaviors led the performers to perceive physically challenging tasks as less demanding (Studies 1, 2, 3, 5), such as perceiving a steep mountain road as less steep (Study 2), a heavy carton as lighter (Study 4), and a long path as shorter (Study 5). These results challenge the conventional wisdom that helping behaviors always come at the cost of the helper and corroborate a growing body of literature showing that helping others could benefit the performer.

Ethnic politics and the diffusion of mobile technology in Africa
Ethnic politics and the diffusion of mobile technology in Africa. Roland Hodler and Paul Raschky. Economics Letters, October 2017, Pages 78-81, http://www.sciencedirect.com/science/article/pii/S0165176517302914
Highlights
• Ethnic power-sharing depends on groups’ population shares (Francois et al. 2015).
• Study on the effect of population shares on mobile phone infrastructure.
• Identification strategy exploits artificial drawing of African borders.
• Larger ethnic groups have more and better mobile phone infrastructure.
• Ethnic power-sharing thus affects the diffusion of mobile technology in Africa.
Abstract: We analyze the effect of an ethnic group’s country-level population share on the mobile phone infrastructure in Africa. Consistent with the African power-sharing arrangements documented by Francois et al. (2015), we find that larger ethnic groups benefit from a higher concentration of mobile phone infrastructure and a higher fraction of UMTS cell sites.

The Economic Impact of China's Anti-Corruption Campaign
The Economic Impact of China's Anti-Corruption Campaign. Nan Chen and Zemin (Zachary) Zhong. University of California Working Paper, June 2017, https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2996009
Abstract: Political corruption is a major problem in governance and is pervasive especially in developing countries. Depending on pre-existing distortions, corruption may benefit economic growth by "greasing the wheel", or it may distort supply of public goods and create inefficiency. Empirically testing the effect of corruption on efficiency and distribution is difficult due to the evasive nature of corruption. We take an alternative approach by investigating the economic impacts of governments' anti-corruption efforts. Our analysis is performed in the context of China's recent anti-corruption campaign under the new president Xi Jinping, the largest of its kind in recent history. As an important initiative of this campaign, the CPC's Provincial Committee of Discipline Inspection (PCDI) send inspection teams to investigate county-level government for potential corruption. The variation in the timing of PCDI visit allows us to use a difference-in-difference design to identify the impact of anti-corruption on local economy. Using a unique administrative dataset of vehicle registration, we find that PCDI visits cause car sales to drop by 3.4% at county level. The effect is surprisingly uniformly distributed across different price tiers. Luxury brands exhibit a similar drop as domestic brands, suggesting corruption's impact permeates a wide income spectrum. Over time, the effect is strengthening: We observe a 2% drop in the first three months of PCDI visit, and a 10% drop one year afterwards. The especially large impact cannot be explained by decline in government officials' consumption behavior, suggesting anti-corruption efforts also affect the private sector.
We validate our empirical strategy by showing that:
(1) the timing of PCDI visits cannot be predicted by observable county characteristics and,
(2) car registrations exhibit parallel pre-treatment trends.
The results are robust to placebo tests and alternative specifications. We find that the effect of PCDI visit on car sales cannot be explained by local economic indicators or monitoring cost as measured by distances to provincial/prefectural governments.

Painting too “Rosie” a picture: The impact of external threat on women’s economic welfare. Jaroslav Tir and Maureen Bailey. Conflict Management and Peace Science, http://www.colorado.edu/polisci/2017/04/19/painting-too-rosie-picture-impact-external-threat-womens-economic-welfare
Abstract: Why is the economic status of women better in one country than another? We maintain that the answer lies in part in the extent of external threat to the homeland territory a country faces. To respond to the threat, states centralize their decision-making, invest more in the military and decrease citizens’ liberties. Associated restrictions and emphases on more “masculine” values create an environment where women’s welfare takes a back seat to the ostensible priority of defending the homeland. Utilizing measures of women’s unemployment from across the world, 1981-2001, we demonstrate that higher levels of territorial threat decrease women’s economic welfare.

China's Lost Generation: Changes in Beliefs and their Intergenerational Transmission
China's Lost Generation: Changes in Beliefs and their Intergenerational Transmission. Gerard Roland and David Yang. NBER Working Paper, May 2017, http://www.nber.org/papers/w23441
Abstract: Beliefs about whether effort pays off govern some of the most fundamental choices individuals make. This paper uses China’s Cultural Revolution to understand how these beliefs can be affected, how they impact behavior, and how they are transmitted across generations. During the Cultural Revolution, China’s college admission system based on entrance exams was suspended for a decade until 1976, effectively depriving an entire generation of young people of the opportunity to access higher education (the “lost generation”). Using data from a nationally representative survey, we compare cohorts who graduated from high school just before and after the college entrance exam was resumed. We find that members of the “lost generation” who missed out on college because they were born just a year or two too early believe that effort pays off to a much lesser degree, even 40 years into their adulthood. However, they invested more in their children’s education, and transmitted less of their changed beliefs to the next generation, suggesting attempts to safeguard their children from sharing their misfortunes.

Effort is costly. People devalue personal rewards that require some measure of physical or even mental effort. Laboratory studies now suggest that physical effort is especially costly when engaged to benefit others. Even when people are willing, however, their efforts are often superficial, with people doing what is necessary but no more.

Corrupting cooperation and how anti-corruption strategies may backfire
Corrupting cooperation and how anti-corruption strategies may backfire. Michael Muthukrishna et al.
Nature Human Behaviour, July 2017, https://www.nature.com/articles/s41562-017-0138
Abstract: Understanding how humans sustain cooperation in large, anonymous societies remains a central question of both theoretical and practical importance. In the laboratory, experimental behavioural research using tools like public goods games suggests that cooperation can be sustained by institutional punishment - analogous to governments, police forces and other institutions that sanction free-riders on behalf of individuals in large societies. In the real world, however, corruption can undermine the effectiveness of these institutions. Levels of corruption correlate with institutional, economic and cultural factors, but the causal directions of these relationships are difficult to determine. Here, we experimentally model corruption by introducing the possibility of bribery. We investigate the effect of structural factors (a leader’s punitive power and economic potential), anti-corruption strategies (transparency and leader investment in the public good) and cultural background. The results reveal that (1) corruption possibilities cause a large (25%) decrease in public good provisioning, (2) empowering leaders decreases cooperative contributions (in direct opposition to typical institutional punishment results), (3) growing up in a more corrupt society predicts more acceptance of bribes and (4) anti-corruption strategies are effective under some conditions, but can further decrease public good provisioning when leaders are weak and the economic potential is poor. These results suggest that a more nuanced approach to corruption is needed and that proposed panaceas, such as transparency, may actually be harmful in some contexts.
Nature Human Behaviour, July 2017, https://www.nature.com/articles/s41562-017-0138
Abstract: Understanding how humans sustain cooperation in large, anonymous societies remains a central question of both theoretical and practical importance. In the laboratory, experimental behavioural research using tools like public goods games suggests that cooperation can be sustained by institutional punishment - analogous to governments, police forces and other institutions that sanction free-riders on behalf of individuals in large societies. In the real world, however, corruption can undermine the effectiveness of these institutions. Levels of corruption correlate with institutional, economic and cultural factors, but the causal directions of these relationships are difficult to determine. Here, we experimentally model corruption by introducing the possibility of bribery. We investigate the effect of structural factors (a leader’s punitive power and economic potential), anti-corruption strategies (transparency and leader investment in the public good) and cultural background. The results reveal that (1) corruption possibilities cause a large (25%) decrease in public good provisioning, (2) empowering leaders decreases cooperative contributions (in direct opposition to typical institutional punishment results), (3) growing up in a more corrupt society predicts more acceptance of bribes and (4) anti-corruption strategies are effective under some conditions, but can further decrease public good provisioning when leaders are weak and the economic potential is poor.

Sentimental Value and Gift Giving: Givers' Fears of Getting It Wrong Prevents Them from Getting It Right
Sentimental Value and Gift Giving: Givers' Fears of Getting It Wrong Prevents Them from Getting It Right. Julian Givi and Jeff Galak. Journal of Consumer Psychology, https://www.journals.elsevier.com/journal-of-consumer-psychology/forthcoming-articles/sentimental-value-and-gift-giving-givers
Abstract: Sentimental value is the value derived from an emotionally-laden item's associations with significant others, or special events or times in one's life. The present research demonstrates that when faced with the choice between sentimentally valuable gifts and gifts with superficial attributes that match the preferences of the recipient, givers give the latter much more often than recipients would prefer to receive such gifts. This asymmetry appears to be driven by givers feeling relatively certain that preference-matching gifts will be well-liked by recipients, but relatively uncertain that the same is true for sentimentally valuable gifts. Three studies demonstrate this gift-giving mismatch and validate the proposed mechanism across a variety of gift-giving occasions and giver-receiver relationship types. The contribution of these findings to the gift-giving literature, as well as directions for future research, are discussed.

Illusory Increases in Font Size Improve Letter Recognition
Illusory Increases in Font Size Improve Letter Recognition. Martin Lages, Stephanie Boyle & Rob Jenkins. Psychological Science, https://www.ncbi.nlm.nih.gov/pubmed/28677992
Abstract: Visual performance of human observers depends not only on the optics of the eye and early sensory encoding but also on subsequent cortical processing and representations. In two experiments, we demonstrated that motion adaptation can enhance as well as impair visual acuity. Observers who experienced an expanding motion aftereffect exhibited improved letter recognition, whereas observers who experienced a contracting motion aftereffect showed impaired letter recognition. We conclude that illusory enlargement and shrinkage of a visual stimulus can modulate visual acuity.

Physical Proximity Increases Persuasive Effectiveness through Visual Imagery
Physical Proximity Increases Persuasive Effectiveness through Visual Imagery. Yanli Jia et al. Journal of Consumer Psychology, https://www.journals.elsevier.com/journal-of-consumer-psychology/forthcoming-articles/physical-proximity-increases-persuasive-effectiveness
Abstract: Six experiments converged on the conclusion that consumers' physical distance from the verbal description of an event or a product can influence their beliefs in its implications. For example, participants' proximity to information about the likelihood of surviving an airline crash can influence their expectations that there would be survivors of a real-life airplane accident, and being close to the description of a commercial product can influence beliefs that the product would be effective. These and other effects are mediated by the vividness of the mental image that participants form on the basis of the information. Consequently, the effects were attenuated when participants are under high cognitive load or when the verbal description lacks the detail necessary for forming a clear mental image. Alternative interpretations in terms of task involvement, perceptual fluency and construal levels are evaluated.

Firm Performance in the Face of Fear: How CEO Moods Affect Firm Performance. Ali Akansu et al. Journal of Behavioral Finance, http://www.tandfonline.com/doi/abs/10.1080/15427560.2017.1338704?journalCode=hbhf20
Abstract: The authors use facial emotion recognition software to quantify CEO mood. Anger or disgust motivates a CEO to work harder to improve his or her situation; thus firm profitability improves in the subsequent quarter. Happy CEOs are less likely to work on hard or unpleasant tasks; thus profitability decreases in the subsequent quarter. In the short term, fear explains the firm's announcement period market performance. However, fear is transient and performance improvement is short term.

Getting the Rich and Powerful to Give
Getting the Rich and Powerful to Give. Judd Kessler, Katherine Milkman & Yiwei Zhang. University of Pennsylvania Working Paper, June 2017, https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2994367
Abstract: What motivates the rich and powerful to exhibit generosity? We explore this important question in a large field experiment. We solicit donations from 32,174 alumni of an Ivy League university, including thousands of rich and powerful alumni. Consistent with past psychology research, we find that the rich and powerful respond dramatically, and differently than others, to being given a sense of agency over the use of donated funds. Gifts from rich and powerful alumni increase by 200-300 percent when they are given a sense of agency. Results suggest that motivating the rich and powerful to act may require tailored interventions.

The world looks better together: How close others enhance our visual experiences
The world looks better together: How close others enhance our visual experiences. Erica Boothby et al. Personal Relationships, http://onlinelibrary.wiley.com/doi/10.1111/pere.12201/abstract
Abstract: People derive a number of benefits from sharing experiences with close others. However, most research on this topic has been restricted to forms of sharing involving explicit socializing, including verbal communication, emotion expression, and behavioral interaction. In two studies, these complexities were eliminated to find out whether merely experiencing visual stimuli (photographs) simultaneously with a close other - without communicating - enhances people's evaluations of those stimuli relative to coexperiencing the same stimuli with a stranger or alone. Compared to when viewers were alone, visual scenes were enhanced (better liked and seen as more real) when coexperienced with a close other and were liked less when coexperienced with a stranger. Implications for close relationships are discussed.

Shareholder Protection and Agency Costs: An Experimental Analysis
Shareholder Protection and Agency Costs: An Experimental Analysis. Jacob LaRiviere, Matthew McMahon & William Neilson. Management Science, http://onlinelibrary.wiley.com/doi/10.1002/bdm.2023/abstract
Abstract: Two competing principal-agent models explain why firms pay dividends. The substitute model proposes that corporate insiders pay dividends to signal and build trust with outside shareholders who lack legal protection. The outcome model, in contrast, surmises that when shareholders have legal protection, they demand dividends from insiders to prevent them from expropriating corporate funds. Either way, dividends represent an agency cost paid to align the interests of shareholders and insiders. Expropriations by insiders and reduced investment by shareholders are also agency costs, but they are difficult to identify with archival data. Using a laboratory experiment, we identify the impact of strengthened shareholder protection on all three types of agency costs. Dividend payout ratios are five times larger with stronger investor protection, insider expropriation ratios are twice as high, and outsider investment falls by 45%. Thus, we find evidence that strengthening shareholder protection introduces previously unidentified agency costs into the insider-investor relationship.

Retirement, Consumption of Political Information, and Political Knowledge
Retirement, Consumption of Political Information, and Political Knowledge. Marcel Garz. European Journal of Political Economy, https://doi.org/10.1016/j.ejpoleco.2017.07.004
Abstract: Democratic societies depend on citizens being informed about candidates and representatives, to allow for optimal voting and political accountability. As the Fourth Estate, news media have a crucial role in this context. However, due to selective exposure, media bias, and endogeneity it is not a priori clear if news consumption increases voter information. Focusing on the increase in leisure time that is associated with retirement, this study investigates whether changes in the consumption of political information affect campaign-related knowledge. For that purpose, I use survey data pertaining to the 2000, 2004, and 2008 US presidential elections. Instrumenting with eligibility for old age benefits, the results show that retirement improves respondents' performance in answering knowledge questions. The effect is mostly driven by additional exposure to newscasts and newspapers. There is also evidence of increasing polarization due to retirement.

The dark side of the sublime: Distinguishing a threat-based variant of awe
Gordon, A. M., Stellar, J. E., Anderson, C. L., McNeil, G. D., Loew, D., & Keltner, D. (2017). The dark side of the sublime: Distinguishing a threat-based variant of awe. Journal of Personality and Social Psychology, 113(2), 310-328. http://dx.doi.org/10.1037/pspp0000120
Abstract: Theoretical conceptualizations of awe suggest this emotion can be more positive or negative depending on specific appraisal processes. However, the emergent scientific study of awe rarely emphasizes its negative side, classifying it instead as a positive emotion. In the present research we tested whether there is a more negative variant of awe that arises in response to vast, complex stimuli that are threatening (e.g., tornadoes, terrorist attack, wrathful god). We discovered people do experience this type of awe with regularity (Studies 1 & 4) and that it differs from other variants of awe in terms of its underlying appraisals, subjective experience, physiological correlates, and consequences for well-being. Specifically, threat-based awe experiences were appraised as lower in self-control and certainty and higher in situational control than other awe experiences, and were characterized by greater feelings of fear (Studies 2a & 2b). Threat-based awe was associated with physiological indicators of increased sympathetic autonomic arousal, whereas positive awe was associated with indicators of increased parasympathetic arousal (Study 3). Positive awe experiences in daily life (Study 4) and in the lab (Study 5) led to greater momentary well-being (compared with no awe experience), whereas threat-based awe experiences did not. This effect was partially mediated by increased feelings of powerlessness during threat-based awe experiences. Together, these findings highlight a darker side of awe.

The Limits of Partisan Prejudice
The Limits of Partisan Prejudice. Yphtach Lelkes and Sean Westwood. Journal of Politics, April 2017, Pages 485-501, http://www.journals.uchicago.edu/doi/abs/10.1086/688223
Abstract: Partisanship increasingly factors into the behavior of Americans in both political and nonpolitical situations, yet the bounds of partisan prejudice are largely unknown. In this paper, we systematically evaluate the limits of partisan prejudice using a series of five studies situated within a typology of prejudice. We find that partisan prejudice predicts suppression of hostile rhetoric toward one's own party, avoidance of members of the opposition, and a desire for preferential treatment for one's own party. While these behaviors may cause incidental or indirect harm to the opposition, we find that even the most affectively polarized - those with the strongest disdain for the opposition - are no more likely to intentionally harm the opposition than those with minimal levels of affective polarization.

Genetic and environmental sources of individual differences in views on aging
Kornadt, A. E., & Kandler, C. (2017). Genetic and environmental sources of individual differences in views on aging. Psychology and Aging, 32(4), 388-399. http://dx.doi.org/10.1037/pag0000174
Abstract: Views on aging are central psychosocial variables in the aging process, but knowledge about their determinants is still fragmental. Thus, the authors investigated the degree to which genetic and environmental factors contribute to individual differences in various domains of views on aging (wisdom, work, fitness, and family), and whether these variance components vary across ages. They analyzed data from 350 monozygotic and 322 dizygotic twin pairs from the Midlife Development in the U.S. (MIDUS) study, aged 25–74. Individual differences in views on aging were mainly due to individual-specific environmental and genetic effects. However, depending on the domain, genetic and environmental contributions to the variance differed. Furthermore, for some domains, variability was larger for older participants; this was attributable to increases in environmental components. This study extends research on genetic and environmental sources of psychosocial variables and stimulates future studies investigating the etiology of views on aging across the life span.

Photographic Memory: The Effects of Volitional Photo Taking on Memory for Visual and Auditory Aspects of an Experience
Photographic Memory: The Effects of Volitional Photo Taking on Memory for Visual and Auditory Aspects of an Experience. Alixandra Barasch et al. Psychological Science, https://www.ncbi.nlm.nih.gov/pubmed/28650721
Abstract: How does volitional photo taking affect unaided memory for visual and auditory aspects of experiences? Across one field and three lab studies, we found that, even without revisiting any photos, participants who could freely take photographs during an experience recognized more of what they saw and less of what they heard, compared with those who could not take any photographs. Further, merely taking mental photos had similar effects on memory. These results provide support for the idea that photo taking induces a shift in attention toward visual aspects and away from auditory aspects of an experience. Additional findings were in line with this mechanism: Participants with a camera had better recognition of aspects of the scene that they photographed than of aspects they did not photograph. Furthermore, participants who used a camera during their experience recognized even nonphotographed aspects better than participants without a camera did. Meta-analyses including all reported studies support these findings.

Journal of Experimental Psychology: Human Perception and Performance, July 2017, Pages 1263-1268, https://www.ncbi.nlm.nih.gov/pubmed/28639823
Abstract: Our movement kinematics provide useful cues about our affective states. Given that our experiences furnish models that help us to interpret our environment, and that a rich source of action experience comes from our own movements, in the present study, we examined whether we use models of our own action kinematics to make judgments about the affective states of others. For example, relative to one's typical kinematics, anger is associated with fast movements. Therefore, the extent to which we perceive anger in others may be determined by the degree to which their movements are faster than our own typical movements. We related participants' walking kinematics in a neutral context to their judgments of the affective states conveyed by observed point-light walkers (PLWs). As predicted, we found a linear relationship between one's own walking kinematics and affective state judgments, such that faster participants rated slower emotions more intensely relative to their ratings for faster emotions. This relationship was absent when observing PLWs where differences in velocity between affective states were removed. These findings suggest that perception of affective states in others is predicted by one's own movement kinematics, with important implications for perception of, and interaction with, those who move differently.

Social Distance Increases Perceived Physical Distance
Social Distance Increases Perceived Physical Distance. Andrea Stevenson Won, Ketaki Shriram & Diana Tamir. Social Psychological and Personality Science, http://journals.sagepub.com/doi/abs/10.1177/1948550617707017
Abstract: Proximity, or spatial closeness, can generate social closeness - the closer people are together, the more they interact, affiliate, and befriend one another. Mediated communication allows people to bridge spatial distance and can increase social closeness between conversational partners, even when they are separated by distance. However, mediated communication may not always make people feel closer together. Here, we test a hypothesis derived from construal theory, about one way in which mediated communication might increase spatial distance, by imposing social distance between two texting partners. In three studies, the social distance generated by a text conversation correlated with estimates of spatial distance. Conversations designed to generate social distance increased estimates of spatial distance. We discuss this relationship in light of the rise in computer-mediated communication.

The Dark Side of Fluency: Fluent Names Increase Drug Dosing
The Dark Side of Fluency: Fluent Names Increase Drug Dosing. Simone Dohle and Amanda Montoya. Journal of Experimental Psychology: Applied, https://www.ncbi.nlm.nih.gov/pubmed/28639797
Abstract: Prior research has demonstrated that high processing fluency influences a wide range of evaluations and behaviors in a positive way. But can high processing fluency also lead to potentially hazardous medical behavior? In 2 controlled experiments, we demonstrate that increasing the fluency of pharmaceutical drug names increases drug dosage. Experiment 1 shows that drugs with fluent names are perceived as safer than those with disfluent names and this effect increases drug dosage for both synthetically produced and herbal drugs. Experiment 2 demonstrates that people chose a higher dosage for themselves and for a child if the drug bears a fluent (vs. disfluent) name. Using linear regression based mediation analysis, we investigated the underlying mechanisms for the effect of fluency on risk perception in more detail. Contrary to prior research, we find that affect, but not familiarity, mediates the fluency-risk link. Our findings suggest that a drug name's fluency is a powerful driver of dosing behavior.

Great Works: A Reciprocal Relationship Between Spatial Magnitudes and Aesthetic Judgment

Psychology of Aesthetics, Creativity, and the Arts, https://www.researchgate.net/publication/317668868_Great_Works_A_Reciprocal_Relationship_Between_Spatial_Magnitudes_and_Aesthetic_Judgment
Abstract: Inspired by the work of the great aestheticians of the 1700s and modern psychological work in spatial cognition, we sought to test the bidirectional relationship between spatial magnitudes and aesthetic value. In a series of 5 experiments, we show that changing the size and position of a painting can impact judgments of its aesthetic value, and conversely. The same painting is believed to be larger when presented as a master artist's versus as a student's work (Experiment 1). Increasing the size of painting makes it seem better (Experiment 2). A painting presented as a master's work appears larger, closer, and better than when presented as a fake (Experiment 3). Master artists' paintings are recommended to be placed higher on the wall than students' paintings (Experiment 4). Finally, when hung high, a painting is judged better than when it is presented at eye level, and worse when it is presented below eye level (Experiment 5). Together these findings demonstrate a reciprocal relationship between the greatness of a work and its spatial position and scale.

Babies and math: A meta-analysis of infants’ simple arithmetic competence

http://dx.doi.org/10.1037/dev0000330
Abstract: Wynn’s (1992) seminal research reported that infants looked longer at stimuli representing “incorrect” versus “correct” solutions of basic addition and subtraction problems and concluded that infants have innate arithmetical abilities. Since then, infancy researchers have attempted to replicate this effect, yielding mixed findings. The present meta-analysis aimed to systematically compile and synthesize all of the primary replications and extensions of Wynn (1992) that have been conducted to date. The synthesis included 12 studies consisting of 26 independent samples and 550 unique infants. The summary effect, computed using a random-effects model, was statistically significant, d = +0.34, p < .001, suggesting that the phenomenon Wynn originally reported is reliable. Five different tests of publication bias yielded mixed results, suggesting that while a moderate level of publication bias is probable, the summary effect would be positive even after accounting for this issue. Out of the 10 metamoderators tested, none were found to be significant, but most of the moderator subgroups were significantly different from a null effect. Although this meta-analysis provides support for Wynn’s original findings, further research is warranted to understand the underlying mechanisms responsible for infants’ visual preferences for “mathematically incorrect” test stimuli.

Abstract: Wynn’s (1992) seminal research reported that infants looked longer at stimuli representing “incorrect” versus “correct” solutions of basic addition and subtraction problems and concluded that infants have innate arithmetical abilities. Since then, infancy researchers have attempted to replicate this effect, yielding mixed findings. The present meta-analysis aimed to systematically compile and synthesize all of the primary replications and extensions of Wynn (1992) that have been conducted to date. The synthesis included 12 studies consisting of 26 independent samples and 550 unique infants. The summary effect, computed using a random-effects model, was statistically significant, d = +0.34, p < .001, suggesting that the phenomenon Wynn originally reported is reliable. Five different tests of publication bias yielded mixed results, suggesting that while a moderate level of publication bias is probable, the summary effect would be positive even after accounting for this issue. Out of the 10 metamoderators tested, none were found to be significant, but most of the moderator subgroups were significantly different from a null effect. Although this meta-analysis provides support for Wynn’s original findings, further research is warranted to understand the underlying mechanisms responsible for infants’ visual preferences for “mathematically incorrect” test stimuli.

Status goods: experimental evidence from platinum credit cards
Bursztyn, Leonardo A.; Ferman, Bruno; Fiorin, Stefano; Kanz, Martin; Rao, Gautam. 2017. Status goods: experimental evidence from platinum credit cards. Policy Research working paper; no. WPS 8064. Washington, D.C.: World Bank Group. http://documents.worldbank.org/curated/en/432691494944222346/Status-goods-experimental-evidence-from-platinum-credit-cards
This paper provides novel evidence on status goods, using a series of field experiments with an Indonesian bank that markets platinum credit cards to high-income customers. In a first experiment, the paper shows that demand for the platinum card greatly exceeds demand for a nondescript control product with identical benefits, suggesting demand for the pure status aspect of the card. Transaction data reveal that platinum cards are more likely to be used in social contexts, implying social image motivations. Combining price variation with information on the use of the card sheds light on the magnitude of the demand for social status. A second experiment provides evidence of positional externalities from the consumption of these status goods. The final experiment shows that increasing self-esteem causally reduces demand for status goods. This suggests that part of the demand for status is psychological in nature, and that social image is a substitute for self-image.

The smartphone and the driver’s cognitive workload: A comparison of Apple, Google, and Microsoft’s intelligent personal assistants
Strayer, D. L., Cooper, J. M., Turrill, J., Coleman, J. R., & Hopman, R. J. (2017). The smartphone and the driver’s cognitive workload: A comparison of Apple, Google, and Microsoft’s intelligent personal assistants. Canadian Journal of Experimental Psychology/Revue canadienne de psychologie expérimentale, 71(2), 93-110. http://dx.doi.org/10.1037/cep0000104
Abstract: The goal of this research was to examine the impact of voice-based interactions using 3 different intelligent personal assistants (Apple’s Siri, Google’s Google Now for Android phones, and Microsoft’s Cortana) on the cognitive workload of the driver. In 2 experiments using an instrumented vehicle on suburban roadways, we measured the cognitive workload of drivers when they used the voice-based features of each smartphone to place a call, select music, or send text messages. Cognitive workload was derived from primary task performance through video analysis, secondary-task performance using the Detection Response Task (DRT), and subjective mental workload. We found that workload was significantly higher than that measured in the single-task drive. There were also systematic differences between the smartphones: The Google system placed lower cognitive demands on the driver than the Apple and Microsoft systems, which did not differ. Video analysis revealed that the difference in mental workload between the smartphones was associated with the number of system errors, the time to complete an action, and the complexity and intuitiveness of the devices. Finally, surprisingly high levels of cognitive workload were observed when drivers were interacting with the devices: “on-task” workload measures did not systematically differ from that associated with a mentally demanding Operation Span (OSPAN) task. The analysis also found residual costs associated using each of the smartphones that took a significant time to dissipate. The data suggest that caution is warranted in the use of smartphone voice-based technology in the vehicle because of the high levels of cognitive workload associated with these interactions

Genetic and environmental sources of individual differences in views on aging
Kornadt, A. E., & Kandler, C. (2017). Genetic and environmental sources of individual differences in views on aging. Psychology and Aging, 32(4), 388-399. http://dx.doi.org/10.1037/pag0000174
Abstract: Views on aging are central psychosocial variables in the aging process, but knowledge about their determinants is still fragmental. Thus, the authors investigated the degree to which genetic and environmental factors contribute to individual differences in various domains of views on aging (wisdom, work, fitness, and family), and whether these variance components vary across ages. They analyzed data from 350 monozygotic and 322 dizygotic twin pairs from the Midlife Development in the U.S. (MIDUS) study, aged 25–74. Individual differences in views on aging were mainly due to individual-specific environmental and genetic effects. However, depending on the domain, genetic and environmental contributions to the variance differed. Furthermore, for some domains, variability was larger for older participants; this was attributable to increases in environmental components. This study extends research on genetic and environmental sources of psychosocial variables and stimulates future studies investigating the etiology of views on aging across the life span.

Investigating the origins of political views: Biases in explanation predict conservative attitudes in children and adults
Investigating the origins of political views: Biases in explanation predict conservative attitudes in children and adults. Larisa Hussak and Andrei Cimpian. Developmental Science, http://internal.psychology.illinois.edu/~acimpian/reprints/HussakCimpian_DevSci.pdf
Abstract: We tested the hypothesis that political attitudes are influenced by an information-processing factor - namely, a bias in the content of everyday explanations. Because many societal phenomena are enormously complex, people's understanding of them often relies on heuristic shortcuts. For instance, when generating explanations for such phenomena (e.g., why does this group have low status?), people often rely on facts that they can retrieve easily from memory - facts that are skewed toward inherent or intrinsic features (e.g., this group is unintelligent). We hypothesized that this bias in the content of heuristic explanations leads to a tendency to (1) view socioeconomic stratification as acceptable and (2) prefer current societal arrangements to alternative ones, two hallmarks of conservative ideology. Moreover, since the inherence bias in explanation is present across development, we expected it to shape children's proto-political judgments as well. Three studies with adults and 4- to 8-year-old children (N = 784) provided support for these predictions: Not only did individual differences in reliance on inherent explanations uniquely predict endorsement of conservative views (particularly the stratification-supporting component; Study 1), but manipulations of this explanatory bias also had downstream consequences for political attitudes in both children and adults (Studies 2 and 3). This work contributes to our understanding of the origins of political attitudes.

http://dx.doi.org/10.1037/edu0000166
Abstract
Research has found that peers influence the academic achievement of children. However, the mechanisms through which peers matter remain underexplored. The present study examined the relationship between peers’ reading skills and children’s own reading skills among 4,215 total second- and third-graders in 294 classrooms across 41 schools. One innovation of the study was the use of social network analysis to directly assess who children reported talking to or seeking help from and whether children who identified peers with stronger reading skills experienced higher reading skills. The results indicated that children on average identified peers with stronger reading skills and the positive association between peer reading skills and children’s own reading achievement was strongest for children with lower initial levels of reading skills. The study has implications for how teachers can leverage the advantages of peers via in-class activities

The costs and benefits of sexual communal motivation for couples coping with vulvodynia
Muise, A., Bergeron, S., Impett, E. A., & Rosen, N. O. (2017). The costs and benefits of sexual communal motivation for couples coping with vulvodynia. Health Psychology, 36(8), 819-827.
http://dx.doi.org/10.1037/hea0000470
Abstract: Objective: Most women with vulvodynia—a prevalent, chronic, vulvovaginal pain condition—engage in intercourse with their partners despite experiencing pain. Their motivation for doing so appears to be interpersonally oriented (e.g., to meet their partners’ sexual needs), but the costs and benefits of such motivations are unknown. We tested whether sexual communal strength (being responsive to a partner’s sexual needs) and unmitigated sexual communion (focusing on a partner’s sexual needs to the exclusion of one’s own needs) were associated with sexual function, and sexual and relationship satisfaction in couples with coping with vulvodynia. Method: In an 8-week daily experience study, 95 women diagnosed with vulvodynia and their partners reported on sexual communal strength, unmitigated sexual communion, sexual function, and sexual and relationship satisfaction on days when sexual activity occurred. Results: On days when women reported higher sexual communal strength, both they and their partners reported greater sexual function and satisfaction, and their partners reported greater relationship satisfaction. When women’s partners reported higher sexual communal strength, both they and the women reported better sexual function, partners reported greater sexual satisfaction, and women reported greater relationship satisfaction. On days when women reported higher unmitigated sexual communion, they reported poorer sexual function and lower sexual satisfaction, and both the women and partners reported lower relationship satisfaction. When women’s partners reported higher unmitigated sexual communion, they reported poorer sexual function. Conclusions: These novel aspects of sexual motivation should be targeted in psychological interventions aimed to improve the sexual and relationship well-being of affected couples.

A large-scale horizontal-vertical illusion produced with small objects separated in depth
Li, Z., & Durgin, F. H. (2017). A large-scale horizontal-vertical illusion produced with small objects separated in depth. Journal of Experimental Psychology: Human Perception and Performance, 43(8), 1473-1479. http://dx.doi.org/10.1037/xhp0000426
Abstract: We conducted two experiments (total N = 81) to investigate the basis for the large-scale horizontal-vertical illusion (HVI), which is typically measured as 15%–20% and has previously been linked to the presence of a ground plane. In a preliminary experiment, vertical rods of similar angular extents that were either large (4.5–7.5 m) and far, or small (0.9–1.5 m) and near, were matched to horizontal extents in a virtual environment by adjustment of horizontal gaps or rods. Large/far objects showed a larger HVI (∼13%) than did small objects (∼7%), as has been shown before, but the horizontal gap normally used to measure the large-scale HVI was not the source of the larger bias. In the second experiment, we found that simply separating the comparison rod in depth from the vertical rod (thus forcing an evaluation of size at a distance) was sufficient to produce a large HVI (17%), even with small rods. The results are interpreted in light of evidence that the large-scale HVI is dependent on ground plane orientation and may be related to differential angular expansion in the visual coding of elevation and azimuth.

http://dx.doi.org/10.1037/str0000036
Abstract: According to Israeli law, citizens aged 20–40 are obligated to fulfill military reserve duty in the Israeli Defense Forces (IDF). Guided by the theory of conservation of resources (COR; Hobfoll, 2001), this study examined the association of resource loss and gain (economic, time, familial, work, and personal resources) with level of reserve combat soldiers’ distress and satisfaction with their service following the termination of their reserve duty. The sample consisted of 139 male Israeli citizens, ages 23–40, serving as reserve soldiers in the IDF. Using an Internet-based questionnaire, prior to the start of their reserve duty (Time 1), the respondents completed questionnaires assessing psychological traits, social support, and psychological distress. Following the reserve service period (Time 2), the respondents completed a short inventory of resource loss and gain related to the service, and assessments of psychological distress and satisfaction with the service. The main results showed that resource loss was higher on average than resource gain and was associated positively with distress and negatively with satisfaction with the service, whereas resource gain was positively associated with satisfaction only. The findings are compatible with COR theory and point to areas in which reserve soldiers could be assisted in fulfilling the task of maintaining national security while simultaneously preserving personal well-being.

The development of real-time stability supports visual working memory performance: Young children’s feature binding can be improved through perceptual structure
Simmering, V. R., & Wood, C. M. (2017). The development of real-time stability supports visual working memory performance: Young children’s feature binding can be improved through perceptual structure. Developmental Psychology, 53(8), 1474-1493.
http://dx.doi.org/10.1037/dev0000358
Abstract: Working memory is a basic cognitive process that predicts higher-level skills. A central question in theories of working memory development is the generality of the mechanisms proposed to explain improvements in performance. Prior theories have been closely tied to particular tasks and/or age groups, limiting their generalizability. The cognitive dynamics theory of visual working memory development has been proposed to overcome this limitation. From this perspective, developmental improvements arise through the coordination of cognitive processes to meet demands of different behavioral tasks. This notion is described as real-time stability, and can be probed through experiments that assess how changing task demands impact children’s performance. The current studies test this account by probing visual working memory for colors and shapes in a change detection task that compares detection of changes to new features versus swaps in color-shape binding. In Experiment 1, 3- to 4-year-old children showed impairments specific to binding swaps, as predicted by decreased real-time stability early in development; 5- to 6-year-old children showed a slight advantage on binding swaps, but 7- to 8-year-old children and adults showed no difference across trial types. Experiment 2 tested the proposed explanation of young children’s binding impairment through added perceptual structure, which supported the stability and precision of feature localization in memory—a process key to detecting binding swaps. This additional structure improved young children’s binding swap detection, but not new-feature detection or adults’ performance. These results provide further evidence for the cognitive dynamics and real-time stability explanation of visual working memory development

Catching fire and spreading it: A glimpse into displayed entrepreneurial passion in crowdfunding campaigns
Li, J. (J.), Chen, X.-P., Kotha, S., & Fisher, G. (2017). Catching fire and spreading it: A glimpse into displayed entrepreneurial passion in crowdfunding campaigns. Journal of Applied Psychology, 102(7), 1075-1090. http://dx.doi.org/10.1037/apl0000217
Abstract: Crowdfunding is an emerging phenomenon that enables entrepreneurs to solicit financial contributions for new projects from mass audiences. Drawing on the elaboration likelihood model of persuasion and emotional contagion theory, the authors examined the importance of displayed entrepreneurial passion when seeking resources in a crowdfunding context. They proposed that entrepreneurs’ displayed passion in the introductory video for a crowdfunding project increases viewers’ experienced enthusiasm about the project (i.e., passion contagion), which then prompts them to contribute financially and to share campaign information via social-media channels. Such sharing further facilitates campaign success. In addition, the authors proposed that perceived project innovativeness strengthens the positive effect of displayed passion on social-media exposure and the funding amount a project garners. They first tested their hypotheses in 2 studies using a combination of survey and archival data from the world’s 2 most popular crowdfunding platforms: Indiegogo (Study 1) and Kickstarter (Study 2). They then conducted an experiment (Study 3) to validate the proposed passion contagion process, and the effect of displayed entrepreneurial passion at the individual level. Findings from these 3 studies significantly supported their hypotheses. The authors discuss the theoretical and practical implications of their findings.

Robin Hood effects on motivation in math: Family interest moderates the effects of relevance interventions

http://dx.doi.org/10.1037/dev0000337
Abstract: Using a cluster randomized field trial, the present study tested whether 2 relevance interventions affected students’ value beliefs, self-concept, and effort in math differently depending on family background (socioeconomic status, family interest (FI), and parental utility value). Eighty-two classrooms were randomly assigned to either 1 of 2 intervention conditions or a control group. Data from 1,916 students (Mage = 14.62, SDage = 0.47) and their predominantly Caucasian middle-class parents were obtained via separate questionnaires. Multilevel regression analyses with cross-level interactions were used to investigate differential intervention effects on students’ motivational beliefs 6 weeks and 5 months after the intervention. Socioeconomic status, FI, and parental utility values were investigated as moderators of the intervention effects. The intervention conditions were especially effective in promoting students’ utility, attainment, intrinsic value beliefs, and effort 5 months after the intervention for students whose parents reported lower levels of math interest. Furthermore, students whose parents reported low math utility values especially profited in terms of their utility and attainment math values 5 months after the intervention. No systematic differential intervention effects were found for socioeconomic status. These results highlight the effectiveness of relevance interventions in decreasing motivational gaps between students from families with fewer or more motivational resources.

Abstract: Using a cluster randomized field trial, the present study tested whether 2 relevance interventions affected students’ value beliefs, self-concept, and effort in math differently depending on family background (socioeconomic status, family interest (FI), and parental utility value). Eighty-two classrooms were randomly assigned to either 1 of 2 intervention conditions or a control group. Data from 1,916 students (Mage = 14.62, SDage = 0.47) and their predominantly Caucasian middle-class parents were obtained via separate questionnaires. Multilevel regression analyses with cross-level interactions were used to investigate differential intervention effects on students’ motivational beliefs 6 weeks and 5 months after the intervention. Socioeconomic status, FI, and parental utility values were investigated as moderators of the intervention effects. The intervention conditions were especially effective in promoting students’ utility, attainment, intrinsic value beliefs, and effort 5 months after the intervention for students whose parents reported lower levels of math interest. Furthermore, students whose parents reported low math utility values especially profited in terms of their utility and attainment math values 5 months after the intervention. No systematic differential intervention effects were found for socioeconomic status. These results highlight the effectiveness of relevance interventions in decreasing motivational gaps between students from families with fewer or more motivational resources. Findings point to the substantial importance of motivational family resources, which have been neglected in previous research.
Not just sticks and stones: Indirect ethnic discrimination leads to greater physiological reactivity
Huynh, V. W., Huynh, Q.-L., & Stein, M.-P. (2017). Not just sticks and stones: Indirect ethnic discrimination leads to greater physiological reactivity. Cultural Diversity and Ethnic Minority Psychology, 23(3), 425-434.
http://dx.doi.org/10.1037/cdp0000138
Abstract
Objectives: We examined the effect of indirect ethnic discrimination on physiological reactivity (i.e., cortisol, blood pressure, heart rate) in Latino emerging adults.
Method: Participants (N = 32) were randomly assigned to be exposed to indirect ethnic discrimination (experimental condition) or not (control condition) while undergoing a cognitive stress task.
Results: Greater total cortisol output was observed in participants in the experimental condition, relative to those in the control condition. No significant differences in heart rate or blood pressure were noted.
Conclusions: Results suggest that witnessing ethnic discrimination affects cortisol recovery responses, but not cardiovascular reactivity. Words that are not intentionally hurtful or directed at a specific person may still “hurt”—affecting biological processes associated with hypothalamic-pituitary-adrenocortical (HPA) axis and potentially leading to long-term health consequences

Music education, academic achievement, and executive functions
Holochwost, S. J., Propper, C. B., Wolf, D. P., Willoughby, M. T., Fisher, K. R., Kolacz, J., . . . Jaffee, S. R. (2017). Music education, academic achievement, and executive functions. Psychology of Aesthetics, Creativity, and the Arts, 11(2), 147-166. http://dx.doi.org/10.1037/aca0000112
Abstract: This study examined whether music education was associated with improved performance on measures of academic achievement and executive functions. Participants were 265 school-age children (Grades 1 through 8, 58% female, and 86% African American) who were selected by lottery to participate in an out-of-school program offering individual- and large-ensemble training on orchestral instruments. Measures of academic achievement (standardized test scores and grades in English language arts and math) were taken from participants’ academic records, whereas executive functions (EFs) were assessed through students’ performance on a computerized battery of common EF tasks. Results indicated that, relative to controls, students in the music education program scored higher on standardized tests, t(217) = 2.74, p = .007; earned better grades in English language arts, t(163) = 3.58, p < .001, and math, t(163) = 2.56, p = .011; and exhibited superior performance on select tasks of EFs and short-term memory. Further analyses revealed that although the largest differences in performance were observed between students in the control group and those who had received the music program for 2 to 3 years, conditional effects were also observed on 3 EF tasks for students who had been in the program for 1 year. These findings are discussed in light of current educational policy, with a particular emphasis on the implications for future research designed to understand the pathways connecting music education and EFs.

False Polarization and False Moderation: Political Opponents Overestimate the Extremity of Each Other's Ideologies but Underestimate Each Other's Certainty
False Polarization and False Moderation: Political Opponents Overestimate the Extremity of Each Other's Ideologies but Underestimate Each Other's Certainty. Craig Blatz and Brett Mercier. Social Psychological and Personality Science, http://journals.sagepub.com/doi/abs/10.1177/1948550617712034
Abstract: Past research finds that people hold moderate views on political issues while believing others are extreme. This false polarization has been demonstrated across a variety of different attitude dimensions and is explained by naive realism, the belief that one holds an unbiased view of reality. We argue that because people believe they see the world objectively, they should be very certain about their opinions, more certain than others expect. In three studies, we tested this false moderation of attitude certainty hypothesis and attempted to replicate past research on false polarization of attitude stance and perceived ideology of others. All three studies revealed a false moderation effect on judgments of certainty. Additionally, we replicate the finding that people false polarize others' ideology but do not find evidence for false polarization of specific stance.

Experiences of nursing students regarding sexual dreams
Gutiérrez-Puertas, L., Márquez-Hernández, V. V., & Aguilera-Manrique, G. (2017). Experiences of nursing students regarding sexual dreams. Dreaming, 27(2), 137-147. http://dx.doi.org/10.1037/drm0000053
Abstract: The aim of this study was to describe the experiences related to sexual dreams in a sample of nursing degree students from the University of Almería, Spain. The research instrument used was an adapted version of the Sexual Dream Experience Questionnaire. This questionnaire is composed of 32 items, divided into 4 dimensions: Joyfulness, Aversion, Familiarity, and Bizarreness. The main results highlighted differences in relation to sex—men have more sexual dreams than women and place more importance on them. While foreplay is involved in the erotic dreams of both men and women, regular partners rarely appear in them. Male dreams tend to include more sexual partners than female dreams and the percentage of men or women who had dreamed about being raped or abused in their sexual dreams was very low. Ultimately, students showed a strong desire to have sexual dreams.

People are willing to pay less for a risky prospect than for its worst possible outcome
Reminder of how averse we are to risks:
Gneezy et al. (2006) documented that people were willing to pay less for a risky prospect than for its worst possible outcome. For instance, people were willing to pay an average of $26.10 for a $50 Barnes and Noble gift card but only $16.12 for a gamble where participants were guaranteed to win either a $50 or $100 gift card, each with a 50% probability. This general finding has been replicated by many independent research teams (e.g., Andreoni & Sprenger, 2011; Newman & Mochon, 2012; Simonsohn, 2009; Wang, Feng, & Keller, 2013; Yang, Vosgerau, & Loewenstein, 2013). *

Effects of professional experience and time pressure on passport-matching performance
Wirth, B. E., & Carbon, C.-C. (2017). An easy game for frauds? Effects of professional experience and time pressure on passport-matching performance. Journal of Experimental Psychology: Applied, 23(2), 138-157. http://dx.doi.org/10.1037/xap0000114
Abstract: Despite extensive research on unfamiliar face matching, little is known about factors that might affect matching performance in real-life scenarios. We conducted 2 experiments to investigate the effects of several such factors on unfamiliar face-matching performance in a passport-check scenario. In Experiment 1, we assessed the effect of professional experience on passport-matching performance. The matching performance of 96 German Federal Police officers working at Munich Airport was compared with that of 48 novices without specific face-matching experience. Police officers significantly outperformed novices, but nevertheless missed a high ratio of frauds. Moreover, the effects of manipulating specific facial features (with paraphernalia like glasses and jewelry, distinctive features like moles and scars, and hairstyle) and of variations in the physical distance between the faces being matched were investigated. Whereas manipulation of physical distance did not have a significant effect, manipulations of facial features impaired matching performance. In Experiment 2, passport-matching performance was assessed in relation to time constraints. Novices matched passports either without time constraints, or under a local time limit (which is typically used in laboratory studies), or under a global time limit (which usually occurs during real-life border controls). Time pressure (especially the global time limit) significantly impaired matching performance.

Holistic processing of static and moving faces
Zhao, M., & Bülthoff, I. (2017). Holistic processing of static and moving faces. Journal of Experimental Psychology: Learning, Memory, and Cognition, 43(7), 1020-1035.
http://dx.doi.org/10.1037/xlm0000368
Abstract: Humans’ face ability develops and matures with extensive experience in perceiving, recognizing, and interacting with faces that move most of the time. However, how facial movements affect 1 core aspect of face ability—holistic face processing—remains unclear. Here we investigated the influence of rigid facial motion on holistic and part-based face processing by manipulating the presence of facial motion during study and at test in a composite face task. The results showed that rigidly moving faces were processed as holistically as static faces (Experiment 1). Holistic processing of moving faces persisted whether facial motion was presented during study, at test, or both (Experiment 2). Moreover, when faces were inverted to eliminate the contributions of both an upright face template and observers’ expertise with upright faces, rigid facial motion facilitated holistic face processing (Experiment 3). Thus, holistic processing represents a general principle of face perception that applies to both static and dynamic faces, rather than being limited to static faces. These results support an emerging view that both perceiver-based and face-based factors contribute to holistic face processing, and they offer new insights on what underlies holistic face processing, how information supporting holistic face processing interacts with each other, and why facial motion may affect face recognition and holistic face processing differently.

Does the cerebellum contribute to human navigation by processing sequential information?
Tedesco, A. M., etal. (2017). Does the cerebellum contribute to human navigation by processing sequential information? Neuropsychology, 31(5), 564-574. http://dx.doi.org/10.1037/neu0000354
Abstract
Objective: Several authors have proposed that the cerebellum has an important role in functions of higher order as a general mode of sequence detection, independently from the nature of the information. The aim of this study was to verify whether the cerebellum mediates the processing of navigational sequential information and to determine whether it is influenced by the modality of the stimuli presentation.
Method: We tested 12 cerebellar patients and 12 healthy age-matched participants in 2 comparable navigational tasks (Walking Corsi Test and the Magic Carpet) requiring to memorizing a sequence of spatial locations. The 2 tasks differ each other for the modality of stimuli presentation: in the Walking Corsi Test the sequence is shown by an examiner that walks on the carpet, whereas in the Magic Carpet it is shown by a computer that lights up the tiles in the sequence. We hypothesize that different mental processes are implicated between the Walking Corsi Test and the Magic Carpet. Indeed, whereas watching the examiner, who performs the sequence on the carpet, allows the patient to simulate the action mentally in the Walking Corsi Test, such simulation cannot be triggered in the Magic Carpet.
Results: Our results showed that cerebellar patients obtained scores significantly lower than control participants only in the Magic Carpet.
Conclusions: We interpreted the patients’ performance as a specific deficit in detecting and ordering single independent stimuli as a sequence, when the maintenance of stimulus–response associations is more demanding.

Perceptions of masculinity and fatherhood among men experiencing homelessness
Rice, A., Kim, J. Y. C., Nguyen, C., Liu, W. M., Fall, K., & Galligan, P. (2017). Perceptions of masculinity and fatherhood among men experiencing homelessness. Psychological Services, 14(2), 257-268. http://dx.doi.org/10.1037/ser0000134
Abstract: This study explored the perceptions of fatherhood held by 11 men living in a homeless shelter. Using consensual qualitative research methodology (CQR; Hill, 2012), we investigated perceptions of masculinity and fatherhood among fathers experiencing homelessness. Participants described (a) their perceptions of masculinity and fatherhood and changes resulting from homelessness, (b) physical and psychological challenges of being a father experiencing homelessness, and (c) expectations of homeless fathers. The fathers generally expressed feelings of low self-esteem related to their perceived difficulty fulfilling the role of providers for their family; however, they also adapted their view of fatherhood to include roles suited to their situation, such as that of guide, teacher, and role model. Suggestions are made for clinicians in helping fathers navigate and develop these roles, and limitations and directions for future research are discussed.

This Hamptons trailer park is a billionaire hotspot - the indescribable cachet that comes with shabby chic
This Hamptons trailer park is a billionaire hotspot. By Jennifer Gould Keil. NY Post, Jul 26, 2017.
https://nypost.com/2017/07/26/this-hamptons-trailer-park-is-a-billionaire-hotspot/
Owning a trailer at the park has become the ultimate status symbol for the tony Long Island town’s summering rich and famous, many of whom use their relatively modest mobile digs as a second pad to escape with the family or even as a glorified changing room after a long day of romping in Montauk’s waves.
There’s also the indescribable cachet that comes with shabby chic.
“All you own is the box of air above the land,” noted a former Montauk Shores trailer owner. “Whoever buys here is essentially buying a 24-foot-wide-by-50-foot-long box of air.”

Characterizing autism-relevant social behavior in poodles (Canis familiaris) via owner report

Abstract: Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder characterized by deficits in social communication and the presence of restricted, repetitive behaviors. It can be difficult to model the complex behavioral features of this disorder with rodent models, which have limited similarity to human behaviors. The domestic dog may be a promising model of complex human behavior, including core features of ASD. The present study examines ASD-relevant social behavior in Miniature and Standard Poodles using an owner-report questionnaire with questions adapted from the Autism Diagnostic Observation Schedule (Lord, Rutter, DiLavore, & Risi, 2000). A previous study identified 3 behavioral constructs examined by this questionnaire: initiation of reciprocal social behaviors, response to social interaction, and communication. In the present study, confirmatory and experimental factor analyses used to assess how collected data fit with the previous model revealed moderate model fit and a similar factorial structure. Between-breed comparisons across these factors and at the individual question level revealed differences between Miniature and Standard Poodles in showing behaviors. Cluster analyses used to group dogs within each breed according to social behavior identified smaller subgroups of dogs with less social behavior across all 3 factors compared with the average within each breed. Within- and between-breed differences in social behavior warrant investigation of genetic variation underlying this complex trait as it relates to ASD-relevant behavior.

The Authoritarian Left Withdraws from Politics: Ideological Asymmetry in the Relationship between Authoritarianism and Political Engagement
The Authoritarian Left Withdraws from Politics: Ideological Asymmetry in the Relationship between Authoritarianism and Political Engagement. Christopher Federico, Emily Fisher & Grace Deason. Journal of Politics, July 2017, Pages 1010-1023, http://www.journals.uchicago.edu/doi/abs/10.1086/692126
Abstract: In this article, we argue that authoritarianism will be associated with reduced political interest and participation to a greater extent among those who identify with the left rather than the right because left-leaning politics - which challenges the status quo - threatens more instability and flux. Using data from the United States, we provide evidence for this first hypothesis. Using multinational European data, we also provide support for a second hypothesis that this interaction would be more evident in "Westernized" contexts, where the traditional left-right difference is clearly defined, than in Eastern European countries, where its meaning is less distinct; and we conceptually replicate the authoritarianism results using a measure of support for "conservation" values favoring security, conformity, and tradition. Together, these results suggest that the lower visibility of left-wing authoritarianism relative to its counterpart on the right may be due in part to greater withdrawal from politics among left-leaning authoritarians.
Keywords: authoritarianism, values, ideology, political engagement.

The role of need for uniqueness in belief in conspiracy theories
"I know things they don't know!": The role of need for uniqueness in belief in conspiracy theories. Anthony Lantian et al. Social Psychology, May/June 2017, Pages 160-173, http://econtent.hogrefe.com/doi/abs/10.1027/1864-9335/a000306
Abstract: In the current research, we investigated whether belief in conspiracy theories satisfies people's need for uniqueness. We found that the tendency to believe in conspiracy theories was associated with the feeling of possessing scarce information about the situations explained by the conspiracy theories (Study 1) and higher need for uniqueness (Study 2). Further two studies using two different manipulations of need for uniqueness (Studies 3 and 4) showed that people in a high need for uniqueness condition displayed higher conspiracy belief than people in a low need for uniqueness condition. This conclusion is strengthened by a small-scale meta-analysis. These studies suggest that conspiracy theories may serve people's desire to be unique, highlighting a motivational underpinning of conspiracy belief.

Meditation for posttraumatic stress: more high-quality data needed to confirm benefits
Hilton, L., et al. (2017). Meditation for posttraumatic stress: Systematic review and meta-analysis. Psychological Trauma: Theory, Research, Practice, and Policy, 9(4), 453-460. http://dx.doi.org/10.1037/tra0000180
Objective: We conducted a systematic review and meta-analysis that synthesized evidence from randomized controlled trials of meditation interventions to provide estimates of their efficacy and safety in treating adults diagnosed with posttraumatic stress disorder (PTSD). This review was based on an established protocol (PROSPERO: CRD42015025782) and is reported according to PRISMA guidelines. Outcomes of interest included PTSD symptoms, depression, anxiety, health-related quality of life, functional status, and adverse events.
Method: Meta-analyses were conducted using the Hartung-Knapp-Sidik-Jonkman method for random-effects models. Quality of evidence was assessed using the Grade of Recommendations Assessment, Development, and Evaluation (GRADE) approach.
Results: In total, 10 trials on meditation interventions for PTSD with 643 participants met inclusion criteria. Across interventions, adjunctive meditation interventions of mindfulness-based stress reduction, yoga, and the mantram repetition program improve PTSD and depression symptoms compared with control groups, but the findings are based on low and moderate quality of evidence. Effects were positive but not statistically significant for quality of life and anxiety, and no studies addressed functional status. The variety of meditation intervention types, the short follow-up times, and the quality of studies limited analyses. No adverse events were reported in the included studies; only half of the studies reported on safety.
Conclusions: Meditation appears to be effective for PTSD and depression symptoms, but in order to increase confidence in findings, more high-quality studies are needed on meditation as adjunctive treatment with PTSD-diagnosed participant samples large enough to detect statistical differences in outcomes.

Rejecting a Bad Option Feels Like Choosing a Good One
Rejecting a Bad Option Feels Like Choosing a Good One. Hanna Perfecto et al. Journal of Personality and Social Psychology, https://www.gsb.stanford.edu/sites/gsb/files/updated_paper_0.pdf
Abstract: Across 4,151 participants, the authors demonstrate a novel framing effect, attribute matching, whereby matching a salient attribute of a decision frame with that of a decision's options facilitates decision-making. This attribute matching is shown to increase decision confidence and, ultimately, consensus estimates by increasing feelings of metacognitive ease. In Study 1, participants choosing the more attractive of two faces or rejecting the less attractive face reported greater confidence in and perceived consensus around their decision. Using positive and negative words, Study 2 showed that the attribute's extremity moderates the size of the effect. Study 3 found decision ease mediates these changes in confidence and consensus estimates. Consistent with a misattribution account, when participants were warned about this external source of ease in Study 4, the effect disappeared. Study 5 extended attribute matching beyond valence to objective judgments. The authors conclude by discussing related psychological constructs as well as downstream consequences.

Cliodynamics: The Journal of Quantitative History and Cultural Evolution, 2017, http://escholarship.org/uc/item/0qc7c973
Abstract: I examine trends in the popularity of first names around the years of USA presidential elections, showing that the names 'Hillary' and 'Hilary' decreased abruptly by more than 90% in popularity following the 1992 election of Hillary Clinton's husband Bill. I show that this outcome is unique to the 1992 election, and argue that it may evidence a "dislike" for Hillary Clinton's public image among both Democratic and Republican voters, which may have eventually contributed to Hillary Clinton's losing the 2016 presidential election.

Recent studies suggest a broad protective relationship between religious participation and population health. A report from the Nurses’ Health Study, which followed up more than 74 000 study participants for 16 years, found that women who attended weekly religious services had a lower mortality rate compared with those who had never attended religious services (actual rates of 845 vs 1229 per 100 000/y, respectively; adjusted hazard ratio, 0.74),4 and those who attended religious services more than once per week had an even lower mortality rate (actual rates of 740 vs 1229 per 100 000/y; adjusted hazard ratio, 0.67), suggesting a possible dose-response relationship.
Multivariable adjustment for extensive confounders did not substantially attenuate the association, suggesting that some of the association might be causal. Although the findings may still be subject to unmeasured factors and residual confounding4 (eg, personal, social, psychological, and socioeconomic characteristics), sensitivity analysis suggested that the association was moderately robust to such unmeasured confounding. Another report from the Nurses’ Health Study noted that attendance at religious services was associated with a reduction in depression risk (adjusted relative risk, 0.71) and a 6-fold reduction in suicide risk (from 6.5 to 1.0 per 100 000/y).5
Possible mechanisms include that religious service participation may enhance the social integration that promotes healthy (eg, tobacco-free) behaviors and provides social support, optimism, or purpose. A recent meta-analysis of 10 prospective studies with more than 136 000 participants showed having higher purpose in life was associated with a reduction (relative risk, 0.83) in all-cause mortality and cardiovascular events.6 Because randomized trials are not possible (assignment of behaviors such as service attendance and life purpose is infeasible), these population-based studies represent the strongest available evidence.
Additional investigations suggest the value of spiritual approaches to medical care within the clinical realm, particularly in the end-of-life setting. In a multisite, prospective study7 of 343 patients with advanced cancer, those whose medical teams (eg, clinicians, chaplains) attended to their spiritual needs had quality-of-life scores at life’s end that were 28% greater on average than those who did not receive such spiritual care (20.3 vs 15.8; highest possible score, 30). In addition, patients reporting high support of their spiritual needs by their medical teams (26%) compared with the large majority who did not receive such care (74%) had a higher odds of transitioning to hospice care (adjusted odds ratio, 3.5).
In contrast, when religious communities supplied spiritual care in the absence of the medical team (43%), patients with terminal illness had a lower odds of receiving hospice services (adjusted odds ratio, 0.37) together with a higher odds of receiving aggressive medical interventions (eg, resuscitation and ventilation) during the last week of life (adjusted odds ratio, 2.6).7 Other studies indicate that most patients with serious illness experience spiritual struggles, such as feeling punished or abandoned by God, associated with decrements in patient well-being.7 All these findings suggest the need for clinicians to integrate spiritual care into end-of-life settings for patients who wish to receive it.
