Similarities in smell and taste preferences in couples increase with relationship duration

Similarities in smell and taste preferences in couples increase with relationship duration. Agata Groyecka et al. Appetite, https://doi.org/10.1016/j.appet.2017.08.035

Abstract: Numerous studies point to partners’ congruence in various domains and note an increase in their compatibility over time. However, none have explored a shift in chemosensory perception related to relationship duration. Here, we examined the relationship between the time heterosexual couples have spent together and the degree to which they share their gustatory and olfactory preferences. Additionally, we investigated whether these preferences are associated with relationship satisfaction. One-hundred couples aged from 18 to 68 years being together for a period between 3 and 540 months rated the pleasantness of a wide variety of olfactory and gustatory stimuli. We showed that both taste and smell preferences are more similar the longer couples have been in a relationship. We also observed a very interesting trend in terms of smell preferences, with relationship satisfaction being negatively related to congruence in smell preferences between partners. We discuss these results from the perspective of evolutionary psychology.

Bias and ignorance in demographic perception -- part of a very general pattern of human psychology

Bias and ignorance in demographic perception. D. Landy, B. Guay and T. Marghetis. Psychonomic Bulletin & Review, https://link.springer.com/article/10.3758/s13423-017-1360-2

Abstract: When it comes to knowledge of demographic facts, misinformation appears to be the norm. Americans massively overestimate the proportions of their fellow citizens who are immigrants, Muslim, LGBTQ, and Latino, but underestimate those who are White or Christian. Previous explanations of these estimation errors have invoked topic-specific mechanisms such as xenophobia or media bias. We reconsidered this pattern of errors in the light of more than 30 years of research on the psychological processes involved in proportion estimation and decision-making under uncertainty. In two publicly available datasets featuring demographic estimates from 14 countries, we found that proportion estimates of national demographics correspond closely to what is found in laboratory studies of quantitative estimates more generally. Biases in demographic estimation, therefore, are part of a very general pattern of human psychology—independent of the particular topic or demographic under consideration—that explains most of the error in estimates of the size of politically salient populations. By situating demographic estimates within a broader understanding of general quantity estimation, these results demand reevaluation of both topic-specific misinformation about demographic facts and topic-specific explanations of demographic ignorance, such as media bias and xenophobia.

Visually conspicuous vehicle modifications influence perceptions of male owner's reproductive strategy and attractiveness

Visually conspicuous vehicle modifications influence perceptions of male owner's reproductive strategy and attractiveness. Daniel J. Kruger and Jessica S. Kruger. EvoS Journal: The Journal of the Evolutionary Studies Consortium. 2016, NEEPS Special Issue pp. 1-12. http://www-personal.umich.edu/~kruger/Krugers_Rims_Evos_2016.pdf

ABSTRACT: Resource displays are an important aspect of male mating effort. Males with relatively higher mating effort may invest proportionally more in economic display at the expense of savings and paternal investment. We predicted that aftermarket motor vehicle modifications would influence perceptions of male vehicle owners. Male owners of vehicles with upgraded wheels, compared to owners of vehicles with stock wheels, would be rated 1a) higher on mating effort, 1b) lower on parental investment, 2a) higher in interest for brief sexual affairs, 2b) lower in interest for long-term committed romantic relationships, 3a) higher in attractiveness to women for brief sexual affairs, and 3b) lower in attractiveness to women for long-term committed romantic relationships. We used before and after modification images of a Jeep Rubicon and Chrysler 300. Results for ratings of Jeep owners supported all hypotheses, but only for male participants. Results for ratings of Chrysler 300 owners supported hypotheses regarding life history dimensions (1a and 1b) and attractiveness to women (3a and 3b) for all participants. Results for ratings of Chrysler 300 owners' relationship interest (2a and 2b) fit the predicted pattern for the upgraded vehicle, but not in comparisons with the stock vehicle.

Openness to Experience and Conscientiousness are consistent predictors of authoritarian tendencies

The Prejudiced Personality? Using the Big Five to Predict Susceptibility to Stereotyping Behavior. Philip Chen and Carl Palmer. American Politics Research, https://doi.org/10.1177/1532673X17719720

Abstract: Although long privileged by scholarship in psychology, personality has only recently been considered as an influential factor for political orientations and actions. In this article, we consider personality’s influence on another important tendency: the proclivity to engage in stereotyping and prejudicial thinking. Using a personality battery included for the first time on the 2012 American National Election Study (ANES), we examine the tendencies of particular personality types to stereotype. Results suggest that the two most politically relevant traits (Openness to Experience and Conscientiousness) are consistent predictors of authoritarian tendencies, which, in turn, produce indirect effects of personality on group-centric policy positions, over and above the effects through political predispositions such as partisanship. Our findings demonstrate the important role of group stereotyping in mediating the effects of personality on policy support.

Keeping Minorities Happy: Hierarchy Maintenance and Whites’ Decreased Support for Highly Identified White Politicians

Keeping Minorities Happy: Hierarchy Maintenance and Whites’ Decreased Support for Highly Identified White Politicians. Sora Jun, Brian Lowery and Lucia Guillory. Personality and Social Psychology Bulletin, http://journals.sagepub.com/doi/abs/10.1177/0146167217722554?journalCode=pspc

Abstract: We test the hypothesis that, to avoid provoking minorities, Whites will withhold their support for White political candidates who are highly identified with their race. In Study 1, we found that White Republicans were less supportive of White candidates the higher the perceived White identity of the candidate due to beliefs that such candidates would provoke racial minorities. In Study 2, we replicated this effect with a manipulation of candidates’ White identity. Study 3 found that Whites reported less support for high-identity candidates when they were led to believe that the hierarchy was unstable rather than stable. Consistent with our hypothesis that those who have the most to lose are most likely to avoid provoking minorities, in Study 4, we found that Whites with high subjective socioeconomic status (SES) varied their support for provocative White candidates as a function of hierarchy stability, whereas those with low subjective SES did not.

The Evil Eye: Eye Gaze and Competitiveness in Social Decision Making

Giacomantonio, M., Jordan, J., Federico, F., van den Assem, M. J., and van Dolder, D. (2017) The Evil Eye: Eye Gaze and Competitiveness in Social Decision Making. Eur. J. Soc. Psychol., http://onlinelibrary.wiley.com/doi/10.1002/ejsp.2336/full

Abstract: We demonstrate that a person's eye gaze and his/her competitiveness are closely intertwined in social decision making. In an exploratory examination of this relationship, Study 1 uses field data from a high-stakes TV game show to demonstrate that the frequency by which contestants gaze at their opponent's eyes predicts their defection in a variant on the prisoner's dilemma. Studies 2 and 3 use experiments to examine the underlying causality and demonstrate that the relationship between gazing and competitive behavior is bi-directional. In Study 2, fixation on the eyes, compared to the face, increases competitive behavior toward the target in an ultimatum game. In Study 3, we manipulate the framing of a negotiation (cooperative vs. competitive) and use an eye tracker to measure fixation number and time spent fixating on the counterpart's eyes. We find that a competitive negotiation elicits more gazing, which in turn leads to more competitive behavior.

Adding Insult to Injury: Sex, Sexual Orientation, and Juror Decision Making in a Case of Intimate Partner Violence

Adding Insult to Injury: Sex, Sexual Orientation, and Juror Decision Making in a Case of Intimate Partner Violence. Marissa Stanziani, Jennifer Cox and C. Adam Coffey. Journal of Homosexuality, http://dx.doi.org/10.1080/00918369.2017.1374066

ABSTRACT: Societal definitions of intimate partner violence (IPV) are highly gendered and heteronormative, resulting in dissonance regarding cases of same-sex IPV. This study explored perceptions of IPV when the context of the case is inconsistent with societal norms regarding sex and sexuality. Mock jurors read a vignette describing a case of alleged IPV in which the sex and sexual orientation of the defendant were manipulated. Participants (N = 415) rendered a verdict and provided ratings of the defendant, victim, and case. Results suggest participants were more confident in a guilty verdict when the defendant was male, compared to female. Further, male defendants were perceived as more morally responsible, but only when the victim was female. Perceptions regarding the crime suggest violence perpetrated by a man against a woman is viewed more adversely than any other condition. Data are discussed in terms of implications for legal decision makers and public policy.

Gender differences in SCRABBLE performance and associated engagement in purposeful practice activities

Gender differences in SCRABBLE performance and associated engagement in purposeful practice activities. Jerad H. Moxley, K. Anders Ericsson and Michael Tuffiash. Psychological Research. https://link.springer.com/article/10.1007/s00426-017-0905-3

Abstract: In two studies, the SCRABBLE skill of male and female participants at the National SCRABBLE Championship was analyzed and revealed superior performance for males. By collecting increasingly detailed information about the participants’ engagement in practice-related activities, we found that over half of the variance in SCRABBLE performance was accounted for by measures of starting ages and the amount of different types of practice activities. Males and females did not differ significantly in the benefits to their performance derived from engagement in SCRABBLE-specific practice alone (purposeful practice). However, gender differences in performance were fully mediated by lower engagement in purposeful practice by females and by their rated preference for playing games of SCRABBLE—an activity where more extended engagement is not associated with increased SCRABBLE performance. General implications from our account of gender differences in skill acquisition are discussed, and future research is proposed for how the duration of engagement in effective deliberate practice can be experimentally manipulated.

Is Doing Your Homework Associated with Becoming More Conscientiousness?

Is Doing Your Homework Associated with Becoming More Conscientiousness? Richard Göllner et al. Journal of Research in Personality. https://doi.org/10.1016/j.jrp.2017.08.007

Highlights
•    More effort in students’ homework is associated with a more positive development in conscientiousness.
•    Effects remain stable after controlling for differences between students increasing and decreasing their homework effort.
•    Associations are found for self-reported and parent-reported personality.

Abstract: Research has shown that sustained homework effort enhances academic performance and that students’ conscientiousness is a powerful predictor of students’ homework effort. But does homework—as homework proponents claim—in turn also influence the development of conscientiousness over time? In the present study, we examined whether students’ homework effort in two subjects (i.e., mathematics and language) was associated with inter-individual differences in students’ development of conscientiousness in the early years of adolescence. Bivariate change models with a total of N = 2,760 students revealed that homework effort and conscientiousness were systematically related over time (Grade 5 to Grade 8). Most importantly, students who invested more effort in their homework showed more positive development in conscientiousness.

Conservatism predicts lapses from vegetarian/vegan diets to meat consumption (through lower social justice concerns and social support)

Conservatism predicts lapses from vegetarian/vegan diets to meat consumption (through lower social justice concerns and social support). Gordon Hodson and Earle Megan. Appetite.  https://doi.org/10.1016/j.appet.2017.08.027

Abstract: Lapses from vegetarian and vegan (i.e., veg*n) food choices to meat consumption are very common, suggesting that sustaining veg*nism is challenging. But little is known about why people return to eating animals after initially deciding to avoid meat consumption. Several potential explanatory factors include personal inconvenience, meat cravings, awkwardness in social settings, or health/nutrition concerns. Here we test the degree to which political ideology predicts lapsing to meat consumption. Past research demonstrates that political ideology predicts present levels of meat consumption, whereby those higher in right-wing ideologies eat more animals, even after controlling for their hedonistic liking of meat (e.g., Dhont & Hodson, 2014). To what extent might political ideology predict whether one has lapsed from veg*n foods back to meat consumption? In a largely representative US community sample (N = 1313) of current and former veg*ns, those higher (vs. lower) in conservatism exhibited significantly greater odds of being a former than current veg*n, even after controlling for age, education, and gender. This ideology-lapsing relation was mediated (i.e., explained) by those higher (vs. lower) in conservatism: (a) adopting a veg*n diet for reasons less centered in justice concerns (animal rights, environment, feeding the poor); and (b) feeling socially unsupported in their endeavor. In contrast, factors such as differential meat craving or lifestyle inconvenience played little mediational role. These findings demonstrate that ideology and justice concerns are particularly relevant to understanding resilience in maintaining veg*n food choices. Implications for understanding why people eat meat, and how to develop intervention strategies, are discussed.

No mutual mate choice for quality in zebra finches: Time to question a widely-held assumption

Wang, D., Forstmeier, W. and Kempenaers, B. (), No mutual mate choice for quality in zebra finches: Time to question a widely-held assumption. Evolution. Accepted Author Manuscript.
https://doi.org/10.1111/evo.13341

Abstract: Studies of mate choice typically assume that individuals prefer high quality mates and select them based on condition-dependent indicator traits. In species with bi-parental care, mutual mate choice is expected to result in assortative mating for quality. When assortment is not perfect, the lower quality pair members are expected to compensate by increased parental investment to secure their partner (positive differential allocation). This framework has been assumed to hold for monogamous species like the zebra finch (Taeniopygia guttata), but progress has been hampered by the difficulty to define individual quality. By combining multiple measures of causes (inbreeding, early nutrition) and consequences (ornaments, displays, fitness components) of variation in quality into a single principal component, we here show that quality variation can be quantified successfully. We further show that variation in quality indeed predicts individual pairing success, presumably because it reflects an individual's vigor or ability to invest in reproduction. However, despite high statistical power, we found no evidence for either assortative mating or for positive differential allocation. We suggest that zebra finch ornaments and displays are not sufficiently reliable for the benefits of choosiness to exceed the costs of competition for the putative best partner. To assess the generality of these findings unbiased quantification of signal honesty and preference strength is required, rather than selective reporting of significant results.

The strategic moral self: Self-presentation shapes moral dilemma judgments

The strategic moral self: Self-presentation shapes moral dilemma judgments. Sarah C. Rom and Paul Conway. Journal of Experimental Social Psychology, Volume 74, January 2018, Pages 24–37
https://doi.org/10.1016/j.jesp.2017.08.003

Abstract: Research has focused on the cognitive and affective processes underpinning dilemma judgments where causing harm maximizes outcomes. Yet, recent work indicates that lay perceivers infer the processes behind others' judgments, raising two new questions: whether decision-makers accurately anticipate the inferences perceivers draw from their judgments (i.e., meta-insight), and, whether decision-makers strategically modify judgments to present themselves favorably. Across seven studies, ***a) people correctly anticipated how their dilemma judgments would influence perceivers' ratings of their warmth and competence, though self-ratings differed (Studies 1–3), b) people strategically shifted public (but not private) dilemma judgments to present themselves as warm or competent depending on which traits the situation favored (Studies 4–6), and, c) self-presentation strategies augmented perceptions of the weaker trait implied by their judgment*** (Study 7). These results suggest that moral dilemma judgments arise out of more than just basic cognitive and affective processes; complex social considerations causally contribute to dilemma decision-making.

Truth or Punishment: Secrecy and Punishing the Self

Truth or Punishment: Secrecy and Punishing the Self. Michael Slepian and Brock Bastian. Personality and Social Psychology Bulletin, https://doi.org/10.1177/0146167217717245

Abstract: We live in a world that values justice; when a crime is committed, just punishment is expected to follow. Keeping one's misdeed secret therefore appears to be a strategic way to avoid (just) consequences. Yet, people may engage in self-punishment to right their own wrongs to balance their personal sense of justice. Thus, those who seek an escape from justice by keeping secrets may in fact end up serving that same justice on themselves (through self-punishment). Six studies demonstrate that thinking about secret (vs. confessed) misdeeds leads to increased self-punishment (increased denial of pleasure and seeking of pain). These effects were mediated by the feeling one deserved to be punished, moderated by the significance of the secret, and were observed for both self-reported and behavioral measures of self-punishment.

Psychological resilience in U.S. military veterans: A 2-year, nationally representative prospective cohort study

Psychological resilience in U.S. military veterans: A 2-year, nationally representative prospective cohort study. Kelly Isaacs et al. Journal of Psychiatric Research, v 84, Jan 2017, pp 301-309, https://doi.org/10.1016/j.jpsychires.2016.10.017

Highlights
•    The current study suggests that most military veterans (67.7%) are resilient.
•    Emotional stability and extraversion were longitudinal predictors of resilience.
•    Gratitude, altruism, and endorsement of purpose in life predicted resilient status.
•    Novel interventions for trauma-exposed veterans may target such modifiable factors.

Abstract: Although many cross-sectional studies have examined the correlates of psychological resilience in U.S. military veterans, few longitudinal studies have identified long-term predictors of resilience in this population. The current prospective cohort study utilized data from a nationally representative sample of 2157 U.S. military veterans who completed web-based surveys in two waves (2011 and 2013) as part of the National Health and Resilience in Veterans Study (NHRVS). Cluster analysis of cumulative lifetime exposure to potentially traumatic events and Wave 2 measures of current symptoms of posttraumatic stress, major depressive, and generalized anxiety disorders was performed to characterize different profiles of current trauma-related psychological symptoms. Different profiles were compared with respect to sociodemographic, clinical, and psychosocial characteristics. A three-group cluster analysis revealed a Control group with low lifetime trauma exposure and low current psychological distress (59.5%), a Resilient group with high lifetime trauma and low current distress (27.4%), and a Distressed group with both high trauma exposure and current distress symptoms (13.1%). These results suggest that the majority of trauma-exposed veterans (67.7%) are psychologically resilient. Compared with the Distressed group, the Resilient group was younger, more likely to be Caucasian, and scored lower on measures of physical health difficulties, past psychiatric history, and substance abuse. Higher levels of emotional stability, extraversion, dispositional gratitude, purpose in life, and altruism, and lower levels of openness to experiences predicted resilient status. Prevention and treatment efforts designed to enhance modifiable factors such as gratitude, sense of purpose, and altruism may help promote resilience in highly trauma-exposed veterans.

Openness to experience predicts intrinsic value shifts after deliberating one's own death

Openness to experience predicts intrinsic value shifts after deliberating one's own death. Mike Prentice, Tim Kasser and Kennon Sheldon. Death Studies,

Abstract: Individual differences that might moderate processes of value shifting during and after deliberating one's own death remain largely unexplored. Two studies measured participants' openness and relative intrinsic-to-extrinsic value orientation (RIEVO) before randomly assigning them to conditions in which they wrote about their own death or dental pain for 6 days, after which RIEVO was assessed again up to 12 days later. When participants confronted thoughts about their own death over a sustained period, high openness to experience helped them shift toward intrinsic values. Implications for understanding openness' role in value reorientation from existential deliberation processes are discussed.
