The U.S. is experiencing high levels of political animosity. Whereas much of the intergroup contact literature has focused on improving intergroup relations by reducing anxieties associated with interacting with other groups, some of the motivation literature suggests a different approach: focusing on immediate rewards, such as fun in the moment. The present study investigated the effectiveness of instructing pairs of participants to focus on immediate rewards, relative to focusing on immediate (anxiety) prevention or a no-goal control condition, for increasing participants’ willingness to interact with members of the opposite political party and making those interactions less aversive. Given prior work suggesting differences between conservatives and liberals in terms of threat aversion and openness, it also investigated whether these results differed for Republicans and Democrats. Ninety-two same-sex Democrat-Republican dyads were recruited from the Sona pool at Arizona State University and randomly assigned to one of three instruction conditions. Before engaging in a 15-minute interaction, participants responded to questions about how well they expected the interactions to go, and after the conversation, they evaluated how they felt during the conversation, their perceptions of their partner’s behaviors, and how willing they would be to interact with the outparty again. It was predicted that participants in the immediate rewards condition would report more positive expectancies of the interactions, more positive impressions of their partners, and greater willingness to interact with the outparty again. It was also expected that Democrats in the immediate rewards condition, and Republicans in the immediate prevention condition, would report more positive expectancies of the interactions, more positive impressions of their partners, and greater willingness to interact with the outparty again relative to Republicans, and to Democrats, in the same conditions. Results of 3 Between-Dyad Condition X 2 Within-Dyad Political Party mixed analyses of variance (ANOVAs) suggested that whereas the immediate rewards condition was associated with marginally more positive expectancies relative to the no-goal control condition, the immediate prevention condition was associated with more enjoyable interactions relative to the no-goal control condition. Although condition effects did not differ significantly by political party, Republicans exhibited some more positive outcomes relative to Democrats.

Do individuals flexibly and adaptively calibrate their motivation, thoughts, feelings, and behaviors in response to changing ecological opportunities and threats? Using a longitudinal six-wave survey data set collected during the COVID-19 pandemic, the study addresses three research questions: are some psychological features or characteristics more or less likely to be calibrated in response to environmental change, are certain types of people more sensitive to these ecological changes, and do individuals become more sensitized or habituated to these changes over time? The results demonstrate that individuals can flexibly adjust their psychology directly relevant to managing COVID-19 infection: people were more strongly motivated to avoid disease and perceived that they were more vulnerable to COVID-19 infection during periods when the threat of COVID-19 infection was high. Political liberals were particularly sensitive to ecological infection changes in adjusting their disease avoidance motivation. Importantly, the study also found a significant quadratic effect of COVID-19 cases on disease avoidance motivation, perceived COVID vulnerability, and preventative behaviors. This indicates that the effect of COVID-19 cases was especially pronounced during the early phase of the pandemic when new cases were relatively low, but diminished as time passed and new cases increased. These findings highlight the adaptive nature of human behavior in response to changing environmental circumstances and underscore the importance of considering both individual and contextual factors in understanding psychological flexibility.

Which evolutionarily important social motives are cultural products about? Songs from the 2020 Billboard Hot 100 year-end chart were rated in terms of their relevance to the fundamental social motives. These songs were thought to be about seeking a romantic partner, followed by maintaining romantic relationships, breakups, and acquiring or maintaining status. Songs were thought to be least about avoiding infectious diseases and caring for children. Relative success of a song was found to be largely unassociated with which motive it reflects but significantly related to simplicity of the lyrics and prestige associated with the artist.

Humans are highly interdependent, living and working in close proximity with many others. From an affordance management perspective, the goal of social perception is to assess and manage potential opportunities and threats afforded by these close others. Social perceivers are thus often motivated to assess particular affordance-relevant characteristics in a target. Frequently, perceivers assess these characteristics via passive observation. Sometimes, however, making such an assessment via observation can be difficult. In these cases, perceivers may instead “affordance test”: actively manipulate the target’s circumstances to reveal (or notably not reveal) cues to the characteristic of interest. There are multiple factors hypothesized to affect whether a perceiver is more likely to passively observe or affordance test that characteristic, including factors related to the characteristic of interest, the situation, the perceiver, and the target. Here, four core hypotheses of this affordance testing framework are tested. In a Preliminary Study (analyzed N = 1301), Study 1 (analyzed N = 559), and Study 2 (analyzed N = 572), highly consistent correlational and experimental evidence was found in support of Hypothesis 1, that the less observable a characteristic is believed to be, the more likely a perceiver is to assess it via affordance testing. In the Preliminary Study, evidence supported Hypothesis 2, that the more important a characteristic is believed to be, the more likely it is to be affordance tested. In Studies 1 and 2, mixed evidence supported Hypothesis 3, that the more urgency or time pressure a perceiver feels, the more likely they are to assess the characteristic of interest via affordance testing. And in Studies 1 and 2, evidence did not support Hypothesis 4, that believed observability and felt urgency interact, such that even characteristics of moderate believed observability are highly likely to be affordance tested under higher felt urgency. Implications of these findings for the affordance testing framework, limitations of the studies, and potential future directions are discussed. In sum, the present work provides promising initial progress in understanding foundational factors that affect when perceivers are likely to affordance test—an important, yet previously understudied, component of the social information-seeking process.

Food-sharing is central to the human experience, involving biological and sociocultural functions. In small-scale societies, sharing food reduces variance in daily food-consumption, allowing effective risk-management, and creating networks of interdependence. It was hypothesized that trust and interdependence would be fostered between people who shared food. Recruiting 221 participants (51% Female, Mage = 19.31), sharing food was found to decrease trust and interdependence in a Trust Game with $3.00 and a Dictator Game with chocolates. Participants trusted the least and gave the fewest chocolates when sharing food. Contrary to lay beliefs about sharing food, breaking bread with strangers may hinder rather than foster trust and giving in situations where competition over limited resources is salient, or under one-shot scenarios where people are unlikely to see each other again in the future.

The present study tested the hypothesis that women dress modestly to signal to other women that they pose no mate poaching threat and are sexually restricted, and that this is especially true for religious women. Participants were 392 Muslim women living in the United States. They read two passages describing fictional situations in which they met with a potential female friend and then indicated what kind of outfit they would wear in both situations. In one situation, the participant obtained a reputation for promiscuity; in the other situation, reputation was not mentioned. I predicted that participants would choose more modest outfits for the promiscuous reputation passage, because if women dress modestly to signal sexual restrictedness, then they should dress more modestly around women with whom they have a reputation for promiscuity—to counteract such a reputation, women may wish to send a strong signal that they are not promiscuous. The hypothesis was partially supported: Less religious women chose more modest outfits for the promiscuous reputation situation than they did for the no reputation situation. This suggests that some women dress modestly to signal sexual restrictedness to other women, but that this is especially true for women who are less religious, not more. More religious women dress more modestly than less religious women, but they may not dress modestly to signal sexual restrictedness. Two important goals for this area of research are to determine the proximate reasons that more religious women dress modestly and to investigate modest dress among non-Muslim religious women.

Previous research used the context-free Big Five model of personality traits to predict social media behaviors. The perspective implicit in this research assumes that expression of the Big Five is free of situational context. This thesis challenges this assumption to address whether people express the same Big Five on social media as offline. In two studies, this thesis addressed three issues: (1) whether there are self-reported differences in the Big Five between social media/online and offline contexts, (2) whether a five-factor structure replicates in the offline and social media context reports, and (3) whether the predictive validity of the Big Five is the same between offline and social media contexts. College students (total N = 2102) reported their offline and social media Big Five. Main findings reveal that, first, all of the Big Five have lower expressions in social media/online than offline, except for those in the lowest quartile of offline trait expressions; possible explanations include regression towards the mean or the environmental impact of social media. Second, a similar factor structure appeared with openness, extraversion, and neuroticism items being the most robust between offline and social media contexts. However, some conscientiousness and agreeableness items did not apply across offline and social media contexts. Third, the Big Five had different predictive patterns of social media behaviors depending on the context. These findings inform that future research may better serve to specify the context of Big Five expression to understand social media behavior.

The present research expands on prior research that demonstrated a prototypical facial expression in response to cute, baby-like Kindchenschema targets. This expression, referred to as the tenderness expression, is recognizable to onlookers as a response to such stimuli. Across two studies, the current research examined if there were differences in perceptions of trustworthiness (Studies 1 and 2) and willingness to trust (Study 2) toward individuals displaying the tenderness expression as compared to a Duchenne smile or a neutral expression. Results indicate the tenderness expression is associated with lower ratings of trustworthiness relative to a smile, but no differences among the expressions on willingness to trust. Exploratory analyses demonstrate a replicated pattern of differences on the Big Five Personality Inventory among these three expressions. While these findings were not consistent with a priori hypotheses, this research provides further insight into the social implications associated with this tenderness expression.

Research and theory in social psychology and related fields indicates that people simultaneously hold many cultural identities. And it is well evidenced across relevant fields (e.g., sociology, marketing, economics) that salient identities are instrumental in a variety of cognitive and behavioral processes, including decision-making. It is not, however, well understood how the relative salience of various cultural identities factors into the process of making identity-relevant choices, particularly ones that require an actor to choose between conflicting sets of cultural values or beliefs. It is also unclear whether the source of that salience (e.g., chronic or situational) is meaningful in this regard. The current research makes novel predictions concerning the roles of cultural identity centrality and cultural identity situational salience in three distinct aspects of the decision-making process: Direction of decision, speed of decision, and emotion related to decision. In doing so, the research highlights two under-researched forms of culture (i.e., political and religious) and uses as the focal dependent variable a decision-making scenario that forces participants to choose between the values of their religious and political cultures and, to some degree, behave in an identity-inconsistent manner. Results indicate main effects of Christian identity centrality and democrat identity centrality on preference for traditional versus gender-neutral (i.e., non-traditional/progressive) restrooms after statistically controlling for covariates. Additionally, results show a significant main effect of democrat identity centrality and a significant interaction effect of Christian and democrat identity centrality on positive emotion linked to the decision. Post hoc analyses further reveal a significant quadratic relationship between Christian identity centrality and emotion related to the decision. There was no effect of situational strength of democrat identity salience on the decision. Neither centrality or situational strength had any effect on the speed with which participants made their decisions. This research theoretically and empirically advances the study of cultural psychology and carries important implications for identity research and judgment and decision-making across a variety of fields, including management, behavioral economics, and marketing.

Although recent research has suggested that motivations such as disease avoidance and self-protection are associated with increased social conservatism, less is known about the impact of other fundamental motivations on political attitudes. This is particularly important given that the currently studied motivations do not consistently push around economic attitudes, which are an important determinant of voting. The current study investigated the impact of a different motivation, status desire, on both economic and social attitudes in a sample of undergraduate students at a large southwestern university. Participants first reported their overall, economic, and social ideology one month before participating in a lab study. Then, in the lab, they were presented either with a vignette designed to elicit status desire, or a closely matched control, before responding to a series of items about economic and social political attitudes. It was predicted that economic conservatives and liberals in the status desire condition would report more economically conservative attitudes relative to their counterparts in the control condition. By contrast, it was predicted that social conservatives in the status desire condition would report more socially conservative attitudes, whereas social liberals in the status desire condition would report more socially liberal attitudes, relative to their counterparts in the control condition. However, the use of hierarchical linear regressions showed no significant effects of motive activation condition, or interactions of motive activation condition with relevant pre-screen political ideology, in predicting either economic or social political attitudes. Implications of these results for future research are discussed.
