Behavioural Consistency Within the Prisoner's Dilemma Game: The Role of Personality and Situation

Mixed‐motive games represent situations that confront people with a conflict between cooperative and non‐cooperative alternatives. Despite this common basis, recent research has shown that the consistency of people's choices across different mixed‐motive games is rather low. The present research examined behavioural consistency within the same mixed‐motive game, by presenting participants with a series of one‐shot Prisoner's Dilemma Games. Across this set of games, payoffs were manipulated in order to intensify or weaken the conflict between self and the other party while maintaining the game's underlying structure. Our findings indicate that significant differences in choice behaviour are observed as a function of both situational (i.e. manipulations of the Prisoner's Dilemma Game's payoff structure) and personality differences (i.e. individual differences in personality and motivational traits). Moreover, our included situational variables and personality features did not interact with each other and were about equally impactful in shaping cooperation. Crucially, however, despite the significant behavioural differences across game variants, considerable consistency in choices was found as well, which suggests that the game's motivational basis reliably impacts choice behaviour in spite of situational and personality variations. We discuss implications for theorizing on mixed‐motive situations and elaborate on the question how cooperation can be promoted. © 2018 European Association of Personality Psychology     

Cultural and Institutional Determinants of Social Dominance Orientation: A Cross‐Cultural Meta‐Analysis of 27 Societies

We investigate macrocontextual antecedents of national levels of Social Dominance Orientation (SDO). The majority of previous research, in contrast, has tended to focus on individual‐level correlates of SDO. We extend research on Social Dominance Theory by modelling national‐level differences in institutional discrimination, macroeconomic development, and value ideologies as broad situational factors affecting SDO mean levels in previous studies. Our hypotheses were tested in a three‐level meta‐analysis of aggregate data from 50,971 individuals in 95 samples from 27 different societies. Strong effects for hierarchy‐attenuating legitimizing ideologies and gender empowerment were found. Aggregate discrimination against arbitrary‐set groups was less consistently linked to SDO, suggesting that these hierarchies are context‐specific. Using mixed‐effects three‐level modelling, the patterns can be generalized to new contexts and suggest a particular institutional and social climate that fosters high SDO.     

The impact of Social Dominance Orientation and Right-Wing Authoritarianism on the relation between Person–Organization fit with commitment, satisfaction, and turnover intentions

This research examined whether Person–Organization fit would mediate the relationships of Social Dominance Orientation and Right-Wing Authoritarianism with the outcome variables of turnover intentions, satisfaction, and commitment. The study was conducted with a military sample and found that both Social Dominance Orientation and Right-Wing Authoritarianism predict greater satisfaction, continuance and normative commitment and that these relationships were mediated by perceived Person–Organization fit. Furthermore, this relation was moderated by the interaction between Social Dominance Orientation and Right-Wing Authoritarianism such that lower scores on Social Dominance Orientation increased the relation between Right-Wing Authoritarianism and P–O fit while higher scores on Social Dominance Orientation lowered that relation.     

Impression management motive and voice: Moderating effects of self‐monitoring,self‐efficacy,and voice instrumentality

The purpose of this study is to examine how employees’ impression management motive influences their voice by considering dispositional and situational variables. Drawing on the theory of self‐motive, we hypothesized that voice would be more positively related to impression management motive than prosocial motive. In addition, based on the interactional approach of motive and trait and trait activation theory, we hypothesized that the relationship between impression management motive and voice would be moderated by self‐monitoring, self‐efficacy, and voice instrumentality. Using a sample of 307 supervisor–subordinate dyads from South Korea, we found that, although prosocial motive had a positive influence on voice, impression management motive had a stronger influence on voice than prosocial motive. We also found that the positive influence of impression management motive on voice was stronger for employees with high levels of self‐monitoring, self‐efficacy, and voice instrumentality. This study helps verify the boundary conditions as to when impression management motive is strongly related to voice. In addition, this study will provide theoretical clues for resolving the inconsistent findings on the relationship between impression management motive and voice.     

Social Value Orientation,Expectations, and Cooperation in Social Dilemmas: A Meta‐analysis

Interdependent situations are pervasive in human life. In these situations, it is essential to form expectations about the others' behaviour to adapt one's own behaviour to increase mutual outcomes and avoid exploitation. Social value orientation, which describes the dispositional weights individuals attach to their own and to another person's outcome, predicts these expectations of cooperation in social dilemmas—an interdependent situation involving a conflict of interests. Yet, scientific evidence is inconclusive about the exact differences in expectations between prosocials, individualists, and competitors. The present meta‐analytic results show that, relative to proselfs (individualists and competitors), prosocials expect more cooperation from others in social dilemmas, whereas individualists and competitors do not significantly differ in their expectations. The importance of these expectations in the decision process is further highlighted by the finding that they partially mediate the well‐established relation between social value orientation and cooperative behaviour in social dilemmas. In fact, even proselfs are more likely to cooperate when they expect their partner to cooperate. Copyright © 2018 European Association of Personality Psychology     

Components of reward in social dilemmas

A social dilemma (Dawes, 1980) may be defined as a situation in which a collection of individuals is faced with a conflict between maximizing selfish interests and maximizing collective interests. The dilemma is based on the fact that if all choose to maximize selfish interests, all are worse off than if all choose to maximize collective interests. In a decomposed social dilemma (Pruitt, 1967), the outcomes are divided into two components: one component is based on one's own choice and the second component is based on the choices made by the others. Using 3-person decomposed games, two types of incentives were contrasted: a positive incentive (bonus) for cooperative choices and a negative incentive (penalty) for noncooperative choices. Two experiments were conducted using male college students. The results of both experiments showed that the positive incentive evoked a higher level of cooperation than the negative incentive. The results are discussed in terms of nonadditive utility components, Pruitt's motivational interpretation, and Kelley and Thibaut's (1978) theory of interdependence.     

Dispositional optimism,self‐framing and medical decision‐making

Self‐framing is an important but underinvestigated area in risk communication and behavioural decision‐making, especially in medical settings. The present study aimed to investigate the relationship among dispositional optimism, self‐frame and decision‐making. Participants (N = 500) responded to the Life Orientation Test‐Revised and self‐framing test of medical decision‐making problem. The participants whose scores were higher than the middle value were regarded as highly optimistic individuals. The rest were regarded as low optimistic individuals. The results showed that compared to the high dispositional optimism group, participants from the low dispositional optimism group showed a greater tendency to use negative vocabulary to construct their self‐frame, and tended to choose the radiation therapy with high treatment survival rate, but low 5‐year survival rate. Based on the current findings, it can be concluded that self‐framing effect still exists in medical situation and individual differences in dispositional optimism can influence the processing of information in a framed decision task, as well as risky decision‐making.     

Quantifying self‐motives: Functional links between dispositional desires

Previous research has sought to establish the existence, or gauge the relative strength, of key self‐evaluation motives (i.e., self‐enhancement, self‐verification, self‐assessment, self‐improvement). Here, we attempted, across five samples, to quantify individual differences in self‐motive strength and explore their empirical ramifications. We devised brief self‐report indices for each self‐motive and checked their factor structure, reliability, and validity. We found that self‐enhancement covaried mainly with self‐verification, and that self‐assessment covaried mainly with self‐improvement, thus validating key hypotheses regarding their functional links. Moreover, self‐enhancement and self‐verification covaried with positive personality traits, as well as with preferences for receiving positive feedback and perceptions of its accuracy. In sum, self‐reported variations in dispositional self‐motive strength form theoretically meaningful patterns. Copyright © 2011 John Wiley & Sons, Ltd.     

The Sticky Anchor Hypothesis: Ego Depletion Increases Susceptibility to Situational Cues

Self‐control depletion has been linked both to increased selfish behavior and increased susceptibility to situational cues. The present research tested two competing hypotheses about the consequence of depletion by measuring how people allocate rewards between themselves and another person. Seven experiments analyzed behavior in standard dictator games and reverse dictator games, settings in which participants could take money from another person. Across all of these experiments, depleted participants made smaller changes to the initial allocation, thereby sticking closer to the default position (anchor) than non‐depleted participants. These findings provide support for a “sticky anchor hypothesis,” which states that the effects of depletion on behavior are influenced by the proximal situational cues rather than by directly stimulating selfishness per se.

Is Political Conservatism Adaptive? Reinterpreting Right‐Wing Authoritarianism and Social Dominance Orientation as Evolved,Sociofunctional Strategies

The Dual Process Model (DPM) explains prejudice and political conservatism as functions of Right‐Wing Authoritarianism (RWA) and a Social Dominance Orientation (SDO; Duckitt, 2001). From an evolutionary perspective, such orientations may represent specific adaptations to coalitional competition in the ancestral environment (Sinn & Hayes, 2016). Supporting this view, recent research suggests the two orientations represent divergent strategies, with RWA pursuing an honest‐cooperator strategy and SDO a deceptive, cooperation‐mimicking strategy (Heylen & Pauwels, 2015). In two studies, we examine additional evidence for an adaptationist interpretation of DPM. Utilizing life history theory, Study 1 finds that RWA reflects the predicted “slow” strategy by endorsing planning and control, investment in family relationships, altruism, and religiosity. In contrast, SDO reflects a “fast” strategy by devaluing planning and control, secure relationships, and altruism. Utilizing rank management theory, Study 2 finds that RWA reflects a prosocial orientation, endorsing coalition building and social networking while rejecting deception and manipulation. In contrast, SDO reflects an exploitive orientation, rejecting coalition building and networking but endorsing ruthless self‐advancement and deceptive tactics. These findings support an adaptationist revision of RWA to recognize its prosocial, honest‐cooperator dimension and of SDO to recognize proself, “dark” tactics seeking power within groups.     

Situational Affordances for Prosocial Behaviour: On the Interaction Between Honesty‐Humility and (Perceived) Interdependence

Individual differences in prosocial behaviour are well‐documented. Increasingly, there has been a focus on the specific situations in which particular personality traits predict prosocial behaviour. HEXACO Honesty‐Humility—the basic trait most consistently linked to prosocial behaviour in prior studies—has been found to predict prosociality most strongly in situations that afford the exploitation of others. Importantly, though, it may be the subjectively perceived situation that affords the behavioural expression of a trait. Following this reasoning, we tested the proposition that Honesty‐Humility would predict prosocial behaviour more strongly in situations characterised by, and perceived to contain, two dimensions of interdependence that can afford exploitation: high conflict and high power. However, across a series of incentivised economic games and two large experience sampling studies, we only found inconsistent evidence for the association between Honesty‐Humility and prosocial behaviour. Furthermore, the link between Honesty‐Humility and prosociality was neither conditional on objective interdependence nor on subjective perceptions of interdependence. Nonetheless, perceptions of conflict and power tracked objective properties of economic games and were related to prosocial behaviour in the lab and field. Future research should take individuals' subjective understanding of situations into account, which may also help understand the (generalisability of the) effect of Honesty‐Humility on prosocial behaviour. © 2019 The Authors.

Does materialism predict racism? materialism as a distinctive social attitude and a predictor of prejudice

Previous research reported that Right‐Wing Authoritarianism (RWA) and Social Dominance Orientation (SDO) constitute the individual's ideological space and are strong dispositional determinants of racism. In the present study, materialism was examined as a third social attitude and a potential predictor of racism. In a student (N = 183) and heterogeneous adult sample (N = 176) analyses revealed that RWA, SDO and materialism constitute three separate dimensions and that each of them explains a unique part of the variance in racism. In addition, Structural Equation Modelling showed that the relationship between materialism and racism was largely mediated by selfish motives. In the discussion we go further into the role of materialism as a third social attitudinal dimension. Copyright © 2006 John Wiley & Sons, Ltd.     

Right‐wing authoritarianism and social dominance orientation and the dimensions of generalized prejudice: A longitudinal test

A Dual Process Model (DPM) approach to prejudice proposes that there should be at least two dimensions of generalized prejudice relating to outgroup stratification and social perception, which should be differentially predicted by Right‐Wing Authoritarianism (RWA) and Social Dominance Orientation (SDO). The current study assessed the causal effects of SDO and RWA on three dimensions of prejudice using a full cross‐lagged longitudinal sample (N = 127). As expected, RWA, but not SDO, predicted prejudice towards ‘dangerous’ groups, SDO, but not RWA, predicted prejudice towards ‘derogated’ groups, and both RWA and SDO predicted prejudice towards ‘dissident’ groups. Results support previously untested causal predictions derived from the DPM and indicate that different forms of prejudice result from different SDO‐ and RWA‐based motivational processes.

The intervening role of social worldviews in the relationship between the five‐factor model of personality and social attitudes

The present research investigates in a student (N = 183) and a voter sample (N = 276) whether the relationships between the Five‐Factor Model (FFM) personality dimensions and social attitudes (i.e. Right‐Wing Authoritarianism [RWA] and Social Dominance Orientation [SDO]) are mediated by social worldviews (i.e. dangerous and jungle worldviews). Two important results were obtained. First, the perception of the world as inherently dangerous and chaotic partially mediated the relationships of the personality dimensions Openness and Neuroticism and the social attitude RWA. Second, the jungle worldview completely mediated the relationships between Agreeableness and SDO, but considerable item overlap between the jungle worldview and SDO was also noted. It was further revealed that acquiescence response set and item overlap had an impact on social worldviews and attitudes, but that their relationships were hardly affected by these biases. The discussion focuses on the status of social worldviews to explain social attitudes. Copyright © 2006 John Wiley & Sons, Ltd.     

Differential Effects of Right‐Wing Authoritarianism and Social Dominance Orientation on Dimensions of Generalized Prejudice in Brazil

Previous research within a dual‐process cognitive‐motivational theory of ideology and prejudice has indicated that dimensions of generalized prejudice are structured around attitudes towards dangerous, derogated and dissident groups, and that these prejudice dimensions are differentially predicted by the ideological attitudes of Right‐Wing Authoritarianism (RWA) and Social Dominance Orientation (SDO). However, to date, these findings have been restricted to New Zealand samples. We describe two studies examining whether the structure of prejudiced attitudes and the differential prediction by RWA and SDO replicate in the Brazilian context, incorporating context‐relevant examples of each group—politicians, those from the northeast region of Brazil, and environmentalists. Results broadly supported the three‐factor structure of dangerous, derogated, and dissident groups. Consistent with previous research, regression and structural equation analyses showed that RWA explained prejudice against dangerous groups, SDO explained prejudice against derogated groups, and both RWA and SDO explained prejudice against dissident groups. This research provides some evidence for the generalizability of the three‐dimensional structure of generalized prejudice and differential prediction by RWA and SDO.

Developmental changes in the attribution of dispositional features

It was hypothesized (1) that with age children would rely increasingly upon information about intention, rather than overt behavior, when attributing dispositional features to others; and (2) that, developmentally, “restricted” dispositional attributions (i.e., those that assume the operation of highly specific situation-response relationships) would precede “generalized” dispositional attributions (which assume the operation of a dispositional concept between broad classes of situations and responses). An experiment is reported that provides support for the first, though not the second, of these hypotheses.     

Themes of Self‐Regulation and Self‐Exploration in the Life Stories of Religious American Conservatives and Liberals

A sample of 128 highly religious (Christian) midlife American adults completed a series of attitudinal and personality trait measures and narrated 12 important autobiographical scenes in their life stories. Individuals high on self‐reported political conservatism tended to accentuate the theme of self‐regulation in their life stories, repeatedly describing important autobiographical scenes wherein they struggled to control, discipline, manage, restrain, protect, or preserve the self. By contrast, individuals high on political liberalism tended to emphasize the theme of self‐exploration, telling stories about expanding, discovering, articulating, or fulfilling the self. Demographics and dispositional traits (especially openness to experience) showed significant associations with conservatism‐liberalism, as well, but these variables did not mitigate the robust relationship between life‐narrative themes and political orientation. The results are discussed in terms of a broadened understanding of personality that conceives of dispositional traits and narrative identity as comprising distinct layers and complementary features of psychological individuality, both implicated in political lives.     

The relationship between the adult attachment and the tendency to judge others as liars

The relationship between 2 dimensions (anxiety and avoidance) of adult attachment and tendency to judge others as liars was examined in this study. We measured 308 participants' adult attachment and tendency to judge others as liars in self‐, other‐, or relationship‐oriented situations. Results supported our hypotheses by showing that (a) anxiety positively predicted the tendency to judge others as liars in self‐oriented situations and (b) avoidance moderated the relationship between anxiety and the tendency to judge others as liars in other‐ and relationship‐oriented situations. Attachment anxiety could positively predict the tendency to judge others as liars only when participants' avoidance was high. Theoretical implications and suggestions for future studies were discussed.     

Social Value Orientation and information search in social dilemmas: An eye-tracking analysis

Previous work has demonstrated that Social Value Orientation (SVO) is related to cooperative behavior in social dilemmas. However, little is known concerning the underlying processes. In two eye-tracking studies investigating decisions in money allocation tasks (Experiment 1) and Public Good Dilemmas (Experiment 2), we show that differences in SVO are accompanied by consistent differences in information search. Decision time, number of fixations, the proportion of inspected information, the degree of attention towards the others’ payoffs, and the number of transitions from and towards others’ payoffs gradually increase with absolute SVO deviation from a pure selfish orientation. Overall these effects seem to be similar for individuals caring positively (i.e., cooperative) or negatively (i.e., competitive) about others. The fact that changes are gradual instead of abrupt indicates that differences in SVO seem to be related to gradual changes in weights given to outcomes for self and others.
