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

Häfner, I., Flunger, B., Dicke, A.-L., Gaspard, H., Brisson, B. M., Nagengast, B., & Trautwein, U. (2017). Robin Hood effects on motivation in math: Family interest moderates the effects of relevance interventions. Developmental Psychology, 53(8), 1522-1539.
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. 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

Zamzow, R. M., Lit, L., Hamilton, S., & Beversdorf, D. Q. (2017). Characterizing autism-relevant social behavior in poodles (Canis familiaris) via owner report. Journal of Comparative Psychology, 131(2), 139-149. http://dx.doi.org/10.1037/com0000060

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.

Trends in First Names Foreshadowed Hillary Clinton's Electoral Defeat

Trends in First Names Foreshadowed Hillary Clinton's Electoral Defeat. Stefano Ghirlanda.
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.

Health and Spirituality

Health and Spirituality. By Tyler J. VanderWeele, PhD; Tracy A. Balboni, MD, MPH; Howard K. Koh, MD, MPH
JAMA. Published online July 27, 2017. doi:10.1001/jama.2017.8136

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.

When Risk Is Weird: Unexplained Transaction Features Lower Valuations

When Risk Is Weird: Unexplained Transaction Features Lower Valuations. Robert Mislavsky and Uri Simonsohn. Management Science, https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2983852

Abstract: We define transactions as weird when they include unexplained features, that is, features not implicitly, explicitly, or self-evidently justified, and propose that people are averse to weird transactions. In six experiments, we show that risky options used in previous research paradigms often attained uncertainty via adding an unexplained transaction feature (e.g., purchasing a coin flip or lottery), and behavior that appears to reflect risk aversion could instead reflect an aversion to weird transactions. Specifically, willingness to pay drops just as much when adding risk to a transaction as when adding unexplained features. Holding transaction features constant, adding additional risk does not further reduce willingness to pay. We interpret our work as generalizing ambiguity aversion to riskless choice.

Is General Intelligence Little More Than the Speed of Higher-Order Processing?

Is General Intelligence Little More Than the Speed of Higher-Order Processing? Anna-Lena Schubert, Dirk Hagemann and Gidon Frischkorn. Journal of Experimental Psychology: General, https://www.ncbi.nlm.nih.gov/pubmed/28703620

Abstract: Individual differences in the speed of information processing have been hypothesized to give rise to individual differences in general intelligence. Consistent with this hypothesis, reaction times (RTs) and latencies of event-related potential have been shown to be moderately associated with intelligence. These associations have been explained either in terms of individual differences in some brain-wide property such as myelination, the speed of neural oscillations, or white-matter tract integrity, or in terms of individual differences in specific processes such as the signal-to-noise ratio in evidence accumulation, executive control, or the cholinergic system. Here we show in a sample of 122 participants, who completed a battery of RT tasks at 2 laboratory sessions while an EEG was recorded, that more intelligent individuals have a higher speed of higher-order information processing that explains about 80% of the variance in general intelligence. Our results do not support the notion that individuals with higher levels of general intelligence show advantages in some brain-wide property. Instead, they suggest that more intelligent individuals benefit from a more efficient transmission of information from frontal attention and working memory processes to temporal-parietal processes of memory storage.

Social Norm Perception in Groups With Outliers

Social Norm Perception in Groups With Outliers. Jennifer Dannals and Dale Miller. Journal of Experimental Psychology: General, https://www.ncbi.nlm.nih.gov/pubmed/28682092

Abstract: Social outliers draw a lot of attention from those inside and outside their group and yet little is known about their impact on perceptions of their group as a whole. The present studies examine how outliers influence observers' summary perceptions of a group's behavior and inferences about the group's descriptive and prescriptive norms. Across 4 studies (N = 1,718) we examine how observers perceive descriptive and prescriptive social norms in groups containing outliers of varying degrees. We find consistent evidence that observers overweight outlying behavior when judging the descriptive and prescriptive norms, but overweight outliers less as they become more extreme, especially in perceptions of the prescriptive norm. We find this pattern across norms pertaining to punctuality (Studies 1-2 and 4) and clothing formality (Study 3) and for outliers who are both prescriptively and descriptively deviant (e.g., late arrivers), as well as for outliers who are only descriptive deviants (e.g., early arrivers). We further demonstrate that observers' perceptions of the group shift in the direction of moderate outliers. This occurs because observers anchor on the outlier's behavior and adjust their recollections of nonoutlying individuals, making their inferences about the group's average behavior more extreme.

Comparison Neglect in Upgrade Decisions

Comparison Neglect in Upgrade Decisions. Aner Sela and Robyn LeBoeuf. Journal of Marketing Research, https://doi.org/10.1509/jmr.14.0394

Abstract: To properly evaluate a potential product upgrade, consumers should compare the upgraded option with the product they already own to assess the upgrade's added utility. However, although consumers explicitly and spontaneously acknowledge the importance of comparing the upgrade with the status quo, the authors find that they often fail to do so. Consequently, consumers frequently buy product upgrades that they would not have bought had they followed their own advice. Five experiments, involving both real and hypothetical upgrade decisions, show that even when the status quo option is represented in the decision context, if consumers are not explicitly prompted to reflect on it or compare it with the upgraded option, they often do not compare it with the upgrade and thus show an elevated likelihood of upgrading. The experiments suggest that this "comparison neglect" increases upgrade likelihood by making people overlook the similarities between the upgraded and status quo options and that it persists even when deliberation effort is high. The findings have important implications for theory, marketing practice, and consumer welfare.

When outgroup negativity trumps ingroup positivity: Fans of the Boston Red Sox and New York Yankees place greater value on rival losses than own-team gains

When outgroup negativity trumps ingroup positivity: Fans of the Boston Red Sox and New York Yankees place greater value on rival losses than own-team gains. Steven Lehr, Meghan Ferreira & Mahzarin Banaji. Group Processes & Intergroup Relations, http://journals.sagepub.com/doi/abs/10.1177/1368430217712834

Abstract: Much research suggests that ingroup positivity is more central than outgroup negativity. We argue that this conclusion is incomplete as a description of the totality of intergroup emotions. In 4 studies, we use a novel measure of willingness to pay for intergroup gains and losses to examine the intergroup emotions of fans of the Boston Red Sox and New York Yankees. Results indicate that pleasure from a powerful rival's losses can outstrip that from gains of one's own group (Studies 1-2), and these patterns extend into domains not immediately relevant to the competition (Studies 3-4). A reversal in the competitive position of the two teams in the 2012-2013 season allowed us to examine whether fluctuations in competitive status moderated this pattern (Studies 3-4). Indeed, fans of the rival teams frequently valued outgroup losses more than ingroup gains, and this effect was particularly strong when one's own team was behind in the rivalry.

Political Conformity: Event-Study Evidence from the United States

Political Conformity: Event-Study Evidence from the United States. Ricardo Perez-Truglia. Review of Economics and Statistics, http://dx.doi.org/10.2139/ssrn.2427146

Abstract: We propose that individuals are more politically active in more like-minded social environments. To test this hypothesis, we combine administrative data from the Federal Election Commission and the United States Postal Service. We identify 45,000 individuals who contributed to Barack Obama’s 2008 presidential campaign and who changed residences either before or after the 2012 election cycle. We examine whether living in an area with a higher share of Democrats causes higher contributions to Obama. We disentangle the direction of causality by exploiting the timing of residential mobility with an event-study analysis. We find that conformity effects are economically significant: increasing the share of Democrats by 1% increases the contribution to Obama by 0.11% (p-value<0 .01="" 27="" a="" analysis.="" attributed="" be="" br="" can="" conformity="" contributions="" counterfactual="" degree="" effects.="" estimates="" find="" for="" geographic="" in="" last="" model="" of="" polarization="" provide="" reduced-form="" that="" the="" to="" uses="" we="">

Limited individual attention and online virality of low-quality information

Limited individual attention and online virality of low-quality information. Xiaoyan Qiu et al. Nature Human Behaviour, June 2017, https://www.nature.com/articles/s41562-017-0132

Abstract: Social media are massive marketplaces where ideas and news compete for our attention. Previous studies have shown that quality is not a necessary condition for online virality and that knowledge about peer choices can distort the relationship between quality and popularity. However, these results do not explain the viral spread of low-quality information, such as the digital misinformation that threatens our democracy. We investigate quality discrimination in a stylized model of an online social network, where individual agents prefer quality information, but have behavioural limitations in managing a heavy flow of information. We measure the relationship between the quality of an idea and its likelihood of becoming prevalent at the system level. We find that both information overload and limited attention contribute to a degradation of the market's discriminative power. A good tradeoff between discriminative power and diversity of information is possible according to the model. However, calibration with empirical data characterizing information load and finite attention in real social media reveals a weak correlation between quality and popularity of information. In these realistic conditions, the model predicts that low-quality information is just as likely to go viral, providing an interpretation for the high volume of misinformation we observe online.

Fact-Checking Effectiveness as a Function of Format and Tone: Evaluating FactCheck.org and FlackCheck.org

Fact-Checking Effectiveness as a Function of Format and Tone: Evaluating FactCheck.org and FlackCheck.org. Dannagal Young et al. Journalism & Mass Communication Quarterly, http://journals.sagepub.com/doi/abs/10.1177/1077699017710453

Abstract: This experiment explores the role of information format (print vs. video) and tone (humorous-nonhumorous) in shaping message interest and belief correction in the context of political fact-checking (N = 525). To understand the mechanisms by which audience misperceptions may be reduced, this experiment tests the belief-correcting effectiveness of a humorous fact-checking video produced by Flackcheck.org, a long-form FactCheck.org print article on the same topic, a nonhumorous video debunking the same set of claims, an unrelated humorous video, and a non-stimulus control group. Mediating psychological mechanisms (message interest, counterargumentation, message discounting) and message perceptions (message confusion) are explored. Results suggest video (humorous or nonhumorous) is an effective way to reduce audience misperceptions by increasing message attention and reducing confusion.

Enhancement of multitasking performance and neural oscillations by transcranial alternating current stimulation

Enhancement of multitasking performance and neural oscillations by transcranial alternating current stimulation. Wan-Yu Hsu et al. PLoS One, May 2017, https://doi.org/10.1371/journal.pone.0178579

Abstract: Multitasking is associated with the generation of stimulus-locked theta (4-7 Hz) oscillations arising from prefrontal cortex (PFC). Transcranial alternating current stimulation (tACS) is a non-invasive brain stimulation technique that influences endogenous brain oscillations. Here, we investigate whether applying alternating current stimulation within the theta frequency band would affect multitasking performance, and explore tACS effects on neurophysiological measures. Brief runs of bilateral PFC theta-tACS were applied while participants were engaged in a multitasking paradigm accompanied by electroencephalography (EEG) data collection. Unlike an active control group, a tACS stimulation group showed enhancement of multitasking performance after a 90-minute session (F1,35 = 6.63, p = 0.01, ηp2 = 0.16; effect size = 0.96), coupled with significant modulation of posterior beta (13-30 Hz) activities (F1,32 = 7.66, p = 0.009, ηp2 = 0.19; effect size = 0.96). Across participant regression analyses indicated that those participants with greater increases in frontal theta, alpha and beta oscillations exhibited greater multitasking performance improvements. These results indicate frontal theta-tACS generates benefits on multitasking performance accompanied by widespread neuronal oscillatory changes, and suggests that future tACS studies with extended treatments are worth exploring as promising tools for cognitive enhancement.
