Abstract. Understanding others is a key component of successful social interactions, and declines in social abilities during later life can lead to social isolation and loneliness. We investigated the relationship between different subcomponents of social cognition and loneliness in a large sample of older adults. We tested perspective-taking and mentalizing skills, alongside self-reported loneliness and social functioning. The results revealed that both loneliness and age correlated significantly with older adults' ability to resist egocentric interference when taking others' perspectives. However, mediation models showed that the effect of loneliness on egocentric tendencies was eliminated when age was accounted for. Therefore, loneliness relates to egocentrism only because egocentric tendencies increase with age, and people experience increasing levels of loneliness and feelings of social isolation with increasing age. Mentalizing and interference from others' perspectives were not influenced by loneliness or age.

Abstract. At the start of the COVID-19 pandemic, unprecedented social distancing rules (including mass school closures) dramatically constrained children’s social lives, jeopardizing human connections that foster prosocial development. This study of 2,516 families of 3–8-year-olds from six countries (China, Sweden, Australia, Italy, the USA, and the United Kingdom) examined whether children’s understanding or feelings about COVID-19 regulations mediated the expected association between COVID-19-related family disruption and children’s prosocial behavior, as indexed by parental ratings. For all six sites, family disruption indirectly predicted reduced prosocial behavior. Negative feelings about COVID-19 regulations mediated this association in all sites except China. Contrariwise, understanding of COVID-19 regulations was not implicated in the link between family disruption and reduced prosocial behavior.

Abstract. The current study focuses on a sample of low- to middle-income school-age Latina girls and their parents and examines how children’s distress proneness interacts with parental empathic accuracy and posttraumatic growth in the wake of the COVID-19 pandemic to predict children’s empathy and prosocial behavior toward unknown others. Approximately 2–3 months into state-mandated stay-at-home orders, 55 parent–daughter dyads were recruited to participate in this four-session longitudinal study. To assess distress proneness, daughters (ages 8–13 years, 100% Latina) identified their degree of distress in response to pandemic-related stressors. Concurrently, their parents reported how they thought their children would respond to these same pandemic-related stressors, which assessed parental empathic accuracy. Parents also completed an adapted version of the Posttraumatic Growth Inventory, which assessed perceived positive outcomes of the COVID-19 pandemic. Upon study completion, a behavioral measure of children’s empathic and prosocial behaviors was collected. Parental empathic accuracy interacted with children’s distress proneness to positively predict children’s affective empathy, such that children’s distress proneness predicted affective empathy at high and mean, but not low, levels of parental empathic accuracy. In a separate analysis, parental posttraumatic growth interacted with children’s distress proneness to positively predict children’s altruistic sharing behavior, such that children’s distress proneness predicted altruistic sharing behavior only at high, but not mean or low, levels of parental posttraumatic growth. The results of this study highlight how positive parental socialization and understanding of children’s tendencies toward distress are associated with children’s empathic and prosocial behaviors, particularly during major global crises.

Abstract. The reinforcement sensitivity theory (RST) proposes that neurobiological systems mediate behavior and their functioning can be associated with personality. The functions and associations of RST systems were revised into fight–flight–freeze system (FFFS), behavioral approach/activation system (rBAS), and behavioral inhibition system (rBIS); however, there is limited study of the revised systems due to lack of validated measures. We investigated scale structure, sex invariance, and psychometric properties of the revised RST questionnaire (rRST-Q). The rRST-Q showed good fit as a 5-factor structure with free interfactor correlations and was sex invariant, and associations with personality and mental health measures were consistent with theory and literature. The rRST-Q is a reliable measure, and its use will help understand the link between brain, personality, and behavior.

Abstract. Based on an integration of socioecological systems and intergroup contact theory, we hypothesized that the context in which intergroup contact takes place moderates its association with attitudes toward refugees. To test this prediction, majority members in Germany reported in three studies ( Ntotal = 695) how often they have had positive and negative direct and indirect contact with refugees in different contexts and their attitudes toward refugees. While the association between direct contact and intergroup attitudes was relatively context-independent, the association between indirect contact and attitudes toward refugees strongly depended on context. Indirect contact was more strongly associated with attitudes toward refugees in contexts with close relationships (family and friends) than in contexts with distanced relationships (newspaper and TV).

Abstract. Previous research found mental contrasting to be an effective self-regulatory strategy. This study explored whether motivational features such as regulatory focus, as promotion focus and prevention focus, could affect people’s spontaneous use of a mental contrasting strategy. The present study hypothesized that promotion focus positively predicts spontaneous mental contrasting. Across the correlational (Study 1) and experimental (Study 2) designs, predominantly promotion-focused university students spontaneously employed more mental contrasting strategies. The implications and suggestions for future research have been discussed.

Abstract. National narcissism is a defensive form of group identity that is contingent on external validation and involves unrealistic belief in the nation’s greatness. Those high in national narcissism are susceptible to ingroup-enhancing narratives. In two pre-registered studies, conducted in Poland ( N = 1,134) and the United Kingdom ( N = 501), we hypothesized and found that national narcissism predicts support for historical policies that emphasize the great achievements and past dominance of one’s own group. Furthermore, we found that the relationship between national narcissism and support for ingroup-enhancing historical policies can be accounted for by the perceived contribution of one’s own country to the world’s history. We discuss implications for research on collective narcissism and historical policies.

Abstract. This study compared attitudes toward multiculturalism and assimilationism among three ethnic groups (Serbs, Croats, and Hungarians) in two neighboring countries (Croatia and Serbia). Additionally, this study examined the predictive role of ethnic identity on aforementioned attitudes directly and indirectly via symbolic threat. The results showed that Croats and Serbs had less positive multicultural and more positive assimilationist attitudes when in a majority position than when in a minority position. Hungarians, a minority in both countries, did not differ between countries. Additionally, symbolic threat mediated the relationship between ethnic identification and both assimilation and multiculturalism only in Croatia. The group status moderated these effects. Our findings confirm the importance of group's status and national context in understanding the majority–minority intergroup dynamic.

Abstract. We explore motivational processes stemming from bicultural identity goals of being Turkish and being German by investigating the effect of identity goal incompleteness versus completeness in the two identity goals on the use of multifinal means to self-symbolize German–Turkish cultural identity goals. Individuals incomplete in either or both identity goals were more likely than individuals complete in both identity goals to engage in multifinal self-symbolizing via social media activity (Experiment 1) and helping (Experiment 2). Incompleteness regarding the two identity goals had an additive effect on effort and elicited distinct patterns of subjectively experienced incompleteness for German and Turkish cultural identity goals (Experiment 2). These findings offer new insights relevant for symbolic self-completion theory and goal systems theory.
