The Effects of Partner Extraversion and Agreeableness on Trust

Existing research has documented the social benefits (i.e., higher popularity and liking) of extraversion and agreeableness. Do these positive reputational consequences extend to social dilemma situations that require trust? We found that people do not trust extraverts more than introverts. Instead, people's trust decisions are guided by their partner's level of agreeableness. In a trust game (Studies 1 and 2), individuals were more likely to trust a partner who was described as agreeable (vs. disagreeable); and, in a laboratory study of work groups, participants trusted more (vs. less) agreeable group members (Study 3). Individuals anticipated others' preferences for agreeable partners and tried to come across as more agreeable, but not more extraverted, in social dilemmas (Study 4). These findings suggest that the social benefits of agreeableness (but not extraversion) extend to social interactions involving trust and highlight the importance of target personality traits in shaping trust decisions.

Personality predictors of social status attainment

The current review summarizes recent advances in research on personality predictors of status attainment. In line with previous research, recent studies indicate that extraverted and narcissistic individuals tend to attain status in groups. Research on mediating processes includes a wide range of underlying motivational, behavioral, and interpersonal perception processes. Most generally speaking, those high in extraversion and narcissism attain status because they are more motivated to do so and thus display assertive behavior that makes them look competent. Situational contexts, group tasks, and cultural contexts can moderate the personality-status links by shaping these processes. For example, studies inspired by evolutionary psychology suggest that dominant individuals are more likely to attain status when dominance is instrumental to address a threatening environment.

Zooming into Real-Life Extraversion – how Personality and Situation Shape Sociability in Social Interactions

What predicts sociable behavior? While main effects of personality and situation characteristics on sociability are well established, there is little evidence for the existence of person-situation interaction effects within real-life social interactions. Moreover, previous research has focused on self-reported behavior ratings, and less is known about the partner’s social perspective, i.e. how partners perceive and influence an actor’s behavior. In the current research, we investigated predictors of sociable behavior in real-life social interactions across social perspectives, including person and situation main effects as well as person-situation interaction effects. In two experience-sampling studies (Study 1: N = 394, US, time-based; Study 2: N = 124, Germany, event-based), we assessed personality traits with self- and informant-reports, self-reported sociable behavior during real-life social interactions, and corresponding information on the situation (categorical situation classifications and dimensional ratings of situation characteristics). In Study 2, we additionally assessed interaction partner-reported actor behavior. Multilevel analyses provided evidence for main effects of personality and situation features, as well as small but consistent evidence for person-situation interaction effects. First, extraverts acted more sociable in general. Second, individuals behaved more sociable in low-effort/positive/low-duty situations (vs. high-effort/negative/high-duty situations). Third, the latter was particularly true for extraverts. Further specific interaction effects were found for the partner’s social perspective. These results are discussed regarding their accordance with different behavioral models (e.g., Trait Activation Theory) and their transferability to other behavioral domains.

The Social Consequences of Personality: Six Suggestions for Future Research

Historically, personality psychology has not focused on the social realm, and social psychology has mostly neglected the influence of individual differences. This has, however, begun to change in the past two decades. Recent years have brought an explosion in creative research programmes on the social consequences of personality. In this paper, we offer a (highly subjective) view on how research on the social consequences of personality should move forward. We note that the existing literature is focused heavily on: traits (at the expense of other personality characteristics), a narrow set of social outcomes (e.g. romantic relationship satisfaction) and effects of personality on one's own outcomes (rather than taking a dyadic/interpersonal perspective). In addition, little attention has been paid to the complex dynamic processes that might account for the links between personality and social outcomes. Based on this, we outline six suggestions for future research on the social consequences of personality: (1) examine a wide range of personality variables and integrate findings across domains; (2) take a broader and more integrative view on social outcomes, including different relationship types, phases and transitions; (3) analyse personality effects on social outcomes from different social perspectives (e.g. self, other and dyad); (4) search for processes that explain the associations between personality and social outcomes; (5) collect rich, multi–method, longitudinal, behavioural datasets with large samples and (6) carefully evaluate the implications of personality effects on social outcomes. We invite researchers to embrace a more collaborative and slower scientific approach to answer the many open questions about the social consequences of personality.

Relationships among Personality, Situational Construal and Social Outcomes

The present study demonstrates a novel way of exploring the relationship between personality and social outcomes by examining an understudied intermediate step: situational construal. Construal is assessed in terms of the degree to which one's description of a situation agrees with others’ descriptions of the same situation (normativity) and the degree to which the description is positively valenced. Participants (N = 256) provided information about their personality and subsequently used the Riverside Situational Q–sort to describe their construal of three in–lab interactions with unacquainted others. A measure of positive behavioural social outcomes was constructed from observer ratings of the video–recorded interactions. Extraversion, agreeableness, openness and neuroticism (negatively) were related to positive behavioural social outcomes, as well as to normativity and positivity of construal. Additionally, normativity and positivity of construal were related to positive social outcomes. However, mediation analyses did not confirm that construal mediates the relation between personality and positive social outcomes. Copyright © 2015 European Association of Personality Psychology

Lab And/Or Field? Measuring Personality Processes and Their Social Consequences

How can researchers study personality processes and their social consequences? In our methodology overview, we first introduce ambulatory assessment methods, which repeatedly measure experiences, physiology and behaviour in people's daily lives based on real–time assessments of self–reports, physiological activity and behavioural observations. Then, we describe methods suitable for assessing personality processes in laboratory settings: self–reports on interpersonal perception, physiological measurements and behavioural observation. We discuss the combination of field and laboratory assessment methods based on their respective strengths and limitations and then highlight ethical issues surrounding the use of these methods. Finally, we propose future avenues for how developments in mobile technology can be used to advance personality research. The increasing availability and the decreasing costs of smartphones, wearable sensors and Internet connectivity offer unique potentials for further understanding the processes underlying how personality exerts broad and important social consequences.

Pathological Personality Traits and Intimacy Processes within Roommate Relationships

Problems with intimacy constitute an important area of interpersonal dysfunction in those with personality pathology. Drawing on the interpersonal process model of intimacy, the present research used a longitudinal dyadic design of same–sex roommate pairs (n = 103) to address how certain pathological personality traits (i.e. Negative Affect, Detachment, and Antagonism) relate to the development of disclosure, perceived responsiveness, and closeness. We expected that participants’ pathological traits would be linked to both their own and their roommate's intimacy development, and that the mechanisms underlying these links would include the endorsement of interpersonal values and/or the dispositional expression of interpersonal behaviour in the roommate relationship. Our findings demonstrate that interpersonal motives and/or behaviours primarily help to explain how individuals with higher levels of Detachment manifest difficulty with intimacy. Implications of our findings for research on personality pathology, normative traits, and intimacy are discussed. Copyright © 2015 European Association of Personality Psychology

Why Not Everyone Gets Their Fair Share of Stress: Adolescent'S Perceived Relationship Affection Mediates Associations between Temperament and Subsequent Stressful Social Events

Temperamental differences are associated with subsequent stressful life events, a phenomenon that has in part been attributed to evocation. However, we remain ignorant about the mechanisms that mediate this process. In the current paper, we test whether differences in ‘perceived relationship affection’ accounted for part of the prospective association between temperament and stressful social event evocation in three social domains, viz. parents, peers and romantic partners. Data were derived from the Tracking Adolescents’ Individual Lives Survey, a large population cohort of Dutch adolescents ( n = 1158). Parent–reported adolescent temperament and adolescent's perceived affection were assessed at age 11 years. Stressful social events that occurred between age 11 and 16 years were captured using the event history calendar. Results indicate that adolescents evoke subsequent stressful social events based on their temperament, and that this association is partially mediated by perceived affection. Importantly, we found evidence for both generic and domain–specific associations, which indicates that social domains are related yet distinct. Taken together, the findings suggest that a search for mediating variables may be a promising way to increase our understanding of the mechanisms that underlie the social stress selection principle, and that perceived relationship affection is one of the candidates.
