Personality and competitiveness: Extraversion, agreeableness, and their aspects, predict self-report

How are basic personality traits linked with individual differences in competitiveness? We examined extraversion and agreeableness, as well as their lower-level aspects (i.e., assertiveness, enthusiasm; compassion, politeness), in relation to both self-reported competitiveness and competitive bidding within two auction games. Participants (N = 304, 56% female) completed comprehensive assessments of personality and competitiveness, along with two hypothetical auction games (a

From Windfall Sharing to Property Ownership: Prosocial Personality Traits in Giving and Taking Dicta

The dictator game is a well-known task measuring prosocial preferences, in which one person divides a fixed amount of windfall money with a recipient. A key factor in real-world transfers of wealth is the concept of property ownership and consequently the related acts of giving and taking. Using a variation of the traditional dictator game (N = 256), we examined whether individual differences under different game frames corresponded with prosocial personality traits from the

Politeness and Compassion Differentially Predict Adherence to Fairness Norms and Interventions to No

Abstract: Adherence to norms and interventions to norm violations are two important forms of social behaviour modelled in economic games. While both appear to serve a prosocial function, they may represent separate mechanisms corresponding with distinct emotional and psychological antecedents, and thus may be predicted by different personality traits. In this study, we compared adherence to fairness norms in the dictator game with responses to violations of the same norms in

When Fair Is Not Equal: Compassion and Politeness Predict Allocations of Wealth Under Different Norm

Growing evidence has highlighted the importance of social norms in promoting prosocial behaviors in economic games. Specifically, individual differences in norm adherence—captured by the politeness aspect of Big Five agreeableness—have been found to predict fair allocations of wealth to one’s partner in the dictator game. Yet, most studies have used neutrally framed paradigms, where players may default to norms of equality in the absence of contextual cues. In this study (N =

Prosocial Personality Traits Differentially Predict Egalitarianism, Generosity, and Reciprocity in E

Recent research has highlighted the role of prosocial personality traits—agreeableness and honesty-humility—in egalitarian distributions of wealth in the dictator game. Expanding on these findings, we ran two studies to examine individual differences in two other forms of prosociality—generosity and reciprocity—with respect to two major models of personality, the Big Five and the HEXACO. Participants (combined N = 560) completed a series of economic games in which allocations

Individual Differences in Good Manners Rather Than Compassion Predict Fair Allocations of Wealth in

One of the most common tools for studying pro‐sociality is the dictator game, in which allocations to one's partner are often described in terms of altruism. However, the motivations driving these allocations may represent either emotional concern for others (compassion), adherence to social norms regarding fairness (politeness), or both. In this article, we apply personality psychology to the study of behavior in the dictator game, in which we examine the discriminant validi

The Role of Interpersonal Traits in Social Decision Making: Exploring Sources of Behavioral Heteroge

Economic games are well-established experimental paradigms for modeling social decision making. A large body of literature has pointed to the heterogeneity of behavior within many of these games, which might be partly explained by broad interpersonal trait dispositions. Using the Big Five and HEXACO (Honesty-Humility, Emotionality, eXtraversion, Agreeableness, Conscientiousness, Openness to Experience) personality frameworks, we review the role of personality in two main clas
