Liberals and Conservatives Rely on Different Sets of Moral Foundations

Abstract: How and why do moral judgments vary across the political spectrum? To test moral foundations theory (J. Haidt & J. Graham, 2007; J. Haidt & C. Joseph, 2004), the authors developed several ways to measure people's use of 5 sets of moral intuitions: Harm/care, Fairness/reciprocity, Ingroup/loyalty, Authority/respect, and Purity/sanctity. Across 4 studies using multiple methods, liberals consistently showed greater endorsement and use of the Harm/care and Fairness/reciprocity foundations compared to the other 3 foundations, whereas conservatives endorsed and used the 5 foundations more equally. This difference was observed in abstract assessments of the moral relevance of foundation-related concerns such as violence or loyalty (Study 1), moral judgments of statements and scenarios (Study 2), "sacredness" reactions to taboo trade-offs (Study 3), and use of foundation-related words in the moral texts of religious sermons (Study 4). These findings help to illuminate the nature and intractability of moral disagreements in the American "culture war."

Understanding and using the Implicit Association Test: III. Meta-analysis of predictive validity.

Abstract: This review of 122 research reports (184 independent samples, 14,900 subjects) found average r = .274 for prediction of behavioral, judgment, and physiological measures by Implicit Association Test (IAT) measures. Parallel explicit (i.e., self-report) measures, available in 156 of these samples (13,068 subjects), also predicted effectively (average r = .361), but with much greater variability of effect size. Predictive validity of self-report was impaired for socially sensitive topics, for which impression management may distort self-report responses. For 32 samples with criterion measures involving Black-White interracial behavior, predictive validity of IAT measures significantly exceeded that of self-report measures. Both IAT and self-report measures displayed incremental validity, with each measure predicting criterion variance beyond that predicted by the other. The more highly IAT and self-report measures were intercorrelated, the greater was the predictive validity of each.

Ambient belonging: how stereotypical cues impact gender participation in computer science.

Abstract: People can make decisions to join a group based solely on exposure to that group's physical environment. Four studies demonstrate that the gender difference in interest in computer science is influenced by exposure to environments associated with computer scientists. In Study 1, simply changing the objects in a computer science classroom from those considered stereotypical of computer science (e.g., Star Trek poster, video games) to objects not considered stereotypical of computer science (e.g., nature poster, phone books) was sufficient to boost female undergraduates' interest in computer science to the level of their male peers. Further investigation revealed that the stereotypical broadcast a masculine stereotype that discouraged women's sense of ambient belonging and subsequent interest in the environment (Studies 2, 3, and 4) but had no similar effect on men (Studies 3, 4). This masculine stereotype prevented women's interest from developing even in environments entirely populated by other women (Study 2). Objects can thus come to broadcast stereotypes of a group, which in turn can deter people who do not identify with these stereotypes from joining that group.

Microbes, mating, and morality: individual differences in three functional domains of disgust.

Abstract: What is the function of disgust? Whereas traditional models have suggested that disgust serves to protect the self or neutralize reminders of our animal nature, an evolutionary perspective suggests that disgust functions to solve 3 qualitatively different adaptive problems related to pathogen avoidance, mate choice, and social interaction. The authors investigated this 3-domain model of disgust across 4 studies and examined how sensitivity to these functional domains relates to individual differences in other psychological constructs. Consistent with their predictions, factor analyses demonstrated that disgust sensitivity partitions into domains related to pathogens, sexuality, and morality. Further, sensitivity to the 3 domains showed predictable differentiation based on sex, perceived vulnerability to disease, psychopathic tendencies, and Big 5 personality traits. In exploring these 3 domains of disgust, the authors introduce a new measure of disgust sensitivity. Appreciation of the functional heterogeneity of disgust has important implications for research on individual differences in disgust sensitivity, emotion, clinical impairments, and neuroscience.

Testing a Social-Cognitive Model of Moral Behavior: The Interactive Influence of Situations and Moral Identity Centrality

Abstract: This article proposes and tests a social-cognitive framework for examining the joint influence of situational factors and the centrality of moral identity on moral intentions and behaviors. The authors hypothesized that if a situational factor increases the current accessibility of moral identity within the working self-concept, then it strengthens the motivation to act morally. In contrast, if a situational factor decreases the current accessibility of moral identity, then it weakens the motivation to act morally. The authors also expected the influence of situational factors to vary depending on the extent to which moral identity was central to a person's overall self-conception. Hypotheses derived from the framework were tested in 4 studies. The studies used recalling and reading a list of the Ten Commandments (Study 1), writing a story using morally laden terms (Study 4), and the presence of performance-based financial incentives (Studies 2 and 3) as situational factors. Participants' willingness to initiate a cause-related marketing program (Study 1), lie to a job candidate during a salary negotiation (Studies 2 and 3), and contribute to a public good (Study 4) were examined. Results provide strong support for the proposed framework.

Social Class, Sense of Control, and Social Explanation

Abstract: Lower social class is associated with diminished resources and perceived subordinate rank. On the basis of this analysis, the authors predicted that social class would be closely associated with a reduced sense of personal control and that this association would explain why lower class individuals favor contextual over dispositional explanations of social events. Across 4 studies, lower social class individuals, as measured by subjective socioeconomic status (SES), endorsed contextual explanations of economic trends, broad social outcomes, and emotion. Across studies, the sense of control mediated the relation between subjective SES and contextual explanations, and this association was independent of objective SES, ethnicity, political ideology, and self-serving biases. Finally, experimentally inducing a higher sense of control attenuated the tendency for lower subjective SES individuals to make more contextual explanations (Study 4). Implications for future research on social class as well as theoretical distinctions between objective SES and subjective SES are discussed.

Reducing intergroup prejudice and conflict using the media: A field experiment in Rwanda.

Abstract: Can the media reduce intergroup prejudice and conflict? Despite the high stakes of this question, understanding of the mass media's role in shaping prejudiced beliefs, norms, and behavior is limited. A yearlong field experiment in Rwanda tested the impact of a radio soap opera featuring messages about reducing intergroup prejudice, violence, and trauma in 2 fictional Rwandan communities. Compared with a control group who listened to a health radio soap opera, listeners' perceptions of social norms and their behaviors changed with respect to intermarriage, open dissent, trust, empathy, cooperation, and trauma healing. However, the radio program did little to change listeners' personal beliefs. Group discussion and emotion were implicated in the process of media influence. Taken together, the results point to an integrated model of behavioral prejudice and conflict reduction that prioritizes the communication of social norms over changes in personal beliefs.

Alone in the Crowd: The Structure and Spread of Loneliness in a Large Social Network

Abstract: The discrepancy between an individual's loneliness and the number of connections in a social network is well documented, yet little is known about the placement of loneliness within, or the spread of loneliness through, social networks. The authors use network linkage data from the population-based Framingham Heart Study to trace the topography of loneliness in people's social networks and the path through which loneliness spreads through these networks. Results indicated that loneliness occurs in clusters, extends up to 3 degrees of separation, is disproportionately represented at the periphery of social networks, and spreads through a contagious process. The spread of loneliness was found to be stronger than the spread of perceived social connections, stronger for friends than family members, and stronger for women than for men. The results advance understanding of the broad social forces that drive loneliness and suggest that efforts to reduce loneliness in society may benefit by aggressively targeting the people in the periphery to help repair their social networks and to create a protective barrier against loneliness that can keep the whole network from unraveling.

Does contact reduce prejudice or does prejudice reduce contact? A longitudinal test of the contact hypothesis among majority and minority groups in three European countries.

Abstract: A widely researched panacea for reducing intergroup prejudice is the contact hypothesis. However, few longitudinal studies can shed light on the direction of causal processes: from contact to prejudice reduction (contact effects) or from prejudice to contact reduction (prejudice effects). The authors conducted a longitudinal field survey in Germany, Belgium, and England with school students. The sample comprised members of both ethnic minorities (n = 512) and ethnic majorities (n = 1,143). Path analyses yielded both lagged contact effects and prejudice effects: Contact reduced prejudice, but prejudice also reduced contact. Furthermore, contact effects were negligible for minority members. These effects were obtained for 2 indicators of prejudice: negative intergroup emotions and desire for social distance. For both majority and minority members, contact effects on negative emotions were stronger when outgroup contacts were perceived as being typical of their group. Contact effects were also mediated by intergroup anxiety. This mediating mechanism was impaired for minority members because of a weakened effect of anxiety on desire for social distance. Theoretical and practical implications of these findings are discussed.

Living with a concealable stigmatized identity: the impact of anticipated stigma, centrality, salience, and cultural stigma on psychological distress and health.

Abstract: The current research provides a framework for understanding how concealable stigmatized identities impact people's psychological well-being and health. The authors hypothesize that increased anticipated stigma, greater centrality of the stigmatized identity to the self, increased salience of the identity, and possession of a stigma that is more strongly culturally devalued all predict heightened psychological distress. In Study 1, the hypotheses were supported with a sample of 300 participants who possessed 13 different concealable stigmatized identities. Analyses comparing people with an associative stigma to those with a personal stigma showed that people with an associative stigma report less distress and that this difference is fully mediated by decreased anticipated stigma, centrality, and salience. Study 2 sought to replicate the findings of Study 1 with a sample of 235 participants possessing concealable stigmatized identities and to extend the model to predicting health outcomes. Structural equation modeling showed that anticipated stigma and cultural stigma were directly related to self-reported health outcomes. Discussion centers on understanding the implications of intraindividual processes (anticipated stigma, identity centrality, and identity salience) and an external process (cultural devaluation of stigmatized identities) for mental and physical health among people living with a concealable stigmatized identity.

Self-affirmation and self-control: affirming core values counteracts ego depletion.

Abstract: Research has established that acts of self-control deplete a resource required for subsequent self-control tasks. The present investigation revealed that a psychological intervention-self-affirmation-facilitates self-control when the resource has been depleted. Experiments 1 and 2 found beneficial effects of self-affirmation on self-control in a depleted state. Experiments 3 and 4 suggested that self-affirmation improves self-control by promoting higher levels (vs. lower levels) of mental construal. Self-affirmation therefore holds promise as a mental strategy that reduces the likelihood of self-control failure.

The effect of the transition to parenthood on relationship quality: an 8-year prospective study.

Abstract: This longitudinal study examined the effect of the birth of the 1st child on relationship functioning using data from 218 couples (436 individuals) over the course of the first 8 years of marriage. Compared with prebirth levels and trajectories, parents showed sudden deterioration following birth on observed and self-reported measures of positive and negative aspects of relationship functioning. The deterioration in these variables was small to medium in size and tended to persist throughout the remaining years of the study. Mothers and fathers showed similar amounts of change after birth. The amount of postbirth deterioration in relationship functioning varied systematically by several characteristics of the individual, the marriage, and the pregnancy itself. In a group of couples who did not have children, results indicated more gradual deterioration in relationship functioning during the first 8 years of marriage without the sudden changes seen in parents, suggesting that the results seen in the parent sample may be due to birth.

Identity fusion: the interplay of personal and social identities in extreme group behavior.

Abstract: The authors propose that when people become fused with a group, their personal and social identities become functionally equivalent. Two hypotheses follow from this proposition. First, activating either personal or social identities of fused persons should increase their willingness to endorse extreme behaviors on behalf of the group. Second, because personal as well as social identities support group-related behaviors of fused persons, the 2 forms of identity may combine synergistically, fostering exceptionally high levels of extreme behavior. Support for these hypotheses came from 5 preliminary studies and 3 experiments. In particular, fused persons were more willing to fight or die for the group than nonfused persons, especially when their personal or social identities had been activated. The authors conclude that among fused persons, both the personal and social self may energize and direct grouprelated behavior. Implications for related theoretical approaches and for conceptualizing the relationship between personal identities, social identities, and group processes are discussed.

A cultural task analysis of implicit independence: comparing North America, Western Europe, and East Asia.

Abstract: Informed by a new theoretical framework that assigns a key role to cultural tasks (culturally prescribed means to achieve cultural mandates such as independence and interdependence) in mediating the mutual influences between culture and psychological processes, the authors predicted and found that North Americans are more likely than Western Europeans (British and Germans) to (a) exhibit focused (vs. holistic) attention, (b) experience emotions associated with independence (vs. interdependence), (c) associate happiness with personal achievement (vs. communal harmony), and (d) show an inflated symbolic self. In no cases were the 2 Western European groups significantly different from one another. All Western groups showed (e) an equally strong dispositional bias in attribution. Across all of the implicit indicators of independence, Japanese were substantially less independent (or more interdependent) than the three Western groups. An explicit self-belief measure of independence and interdependence showed an anomalous pattern. These data were interpreted to suggest that the contemporary American ethos has a significant root in both Western cultural heritage and a history of voluntary settlement. Further analysis offered unique support for the cultural task analysis.

Why do dominant personalities attain influence in face-to-face groups? The competence-signaling effects of trait dominance.

Abstract: Individuals high in the personality trait dominance consistently attain high levels of influence in groups. Why they do is unclear, however, because most group theories assert that people cannot attain influence simply by behaving assertively and forcefully; rather, they need to possess superior task abilities and leadership skills. In the present research, the authors proposed that individuals high in trait dominance attain influence because they behave in ways that make them appear competent—even when they actually lack competence. Two studies examined task groups using a social relations analysis of peer perceptions (D. A. Kenny & L. LaVoie, 1984). The authors found that individuals higher in trait dominance were rated as more competent by fellow group members, outside peer observers, and research staff members, even after controlling for individuals’ actual abilities. Furthermore, frequency counts of discrete behaviors showed that dominance predicts the enactment of competence-signaling behaviors, which in turn predicts peer ratings of competence. These findings extend researchers’ understanding of trait dominance, hierarchies in groups, and perceptions of competence and abilities.

Cultural borders and mental barriers: the relationship between living abroad and creativity.

Abstract: Despite abundant anecdotal evidence that creativity is associated with living in foreign countries, there is currently little empirical evidence for this relationship. Five studies employing a multimethod approach systematically explored the link between living abroad and creativity. Using both individual and dyadic creativity tasks, Studies 1 and 2 provided initial demonstrations that time spent living abroad (but not time spent traveling abroad) showed a positive relationship with creativity. Study 3 demonstrated that priming foreign living experiences temporarily enhanced creative tendencies for participants who had previously lived abroad. In Study 4, the degree to which individuals had adapted to different cultures while living abroad mediated the link between foreign living experience and creativity. Study 5 found that priming the experience of adapting to a foreign culture temporarily enhanced creativity for participants who had previously lived abroad. The relationship between living abroad and creativity was consistent across a number of creativity measures (including those measuring insight, association, and generation), as well as with masters of business administration and undergraduate samples, both in the United States and Europe, demonstrating the robustness of this phenomenon.

The implications of Big Five standing for the distribution of trait manifestation in behavior: fifteen experience-sampling studies and a meta-analysis.

Abstract: One of the fundamental questions in personality psychology is whether and how strongly trait standing relates to the traits that people actually manifest in their behavior when faced with real pressures and real consequences of their actions. One reason this question is fundamental is the common belief that traits do not predict how individuals behave, which leads to the reasonable conclusion that traits are not important to study. However, this conclusion is surprising given that there is almost no data on the ability of traits to predict distributions of naturally occurring, representative behaviors of individuals (and that there are many studies showing that traits do indeed predict specific behaviors). The authors describe a meta-analysis of 15 experience-sampling studies, conducted over the course of 8 years, amassing over 20,000 reports of trait manifestation in behavior. Participants reported traits on typical self-report questionnaires, then described their current behavior multiple times per day for several days as the behavior was occurring. Results show that traits, contrary to expectations, were strongly predictive of individual differences in trait manifestation in behavior, predicting average levels with correlations between .42 and .56 (approaching .60 for stringently restricted studies). Several other ways of summarizing trait manifestation in behavior were also predicted from traits. These studies provide evidence that traits are powerful predictors of actual manifestation of traits in behavior.

Self-regulatory failure and intimate partner violence perpetration.

Abstract: Five studies tested the hypothesis that self-regulatory failure is an important predictor of intimate partner violence (IPV) perpetration. Study 1 participants were far more likely to experience a violent impulse during conflictual interaction with their romantic partner than they were to enact a violent behavior, suggesting that self-regulatory processes help individuals refrain from perpetrating IPV when they experience a violent impulse. Study 2 participants high in dispositional self-control were less likely to perpetrate IPV, in both cross-sectional and residualized-lagged analyses, than were participants low in dispositional self-control. Study 3 participants verbalized more IPV-related cognitions if they responded immediately to partner provocations than if they responded after a 10-s delay. Study 4 participants whose self-regulatory resources were experimentally depleted were more violent in response to partner provocation (but not when unprovoked) than were nondepleted participants. Finally, Study 5 participants whose self-regulatory resources were experimentally bolstered via a 2-week training regimen exhibited less violent inclinations than did participants whose self-regulatory resources had not been bolstered. These findings hint at the power of incorporating self-regulation dynamics into predictive models of IPV perpetration.

The social costs of emotional suppression: a prospective study of the transition to college

Abstract: There is growing interest in understanding how emotion regulation affects adaptation. The present study examined expressive suppression (which involves inhibiting the overt expression of emotion) and how it affects a critical domain of adaptation, social functioning. This investigation focused on the transition to college, a time that presents a variety of emotional and social challenges. Analyses focused on 2 components of suppression: a stable component, representing individual differences expressed both before and after the transition, and a dynamic component, representing variance specific to the new college context. Both components of suppression predicted lower social support, less closeness to others, and lower social satisfaction. These findings were robustly corroborated across weekly experience reports, self-reports, and peer reports and are consistent with a theoretical framework that defines emotion regulation as a dynamic process shaped by both stable person factors and environmental demands.

Disgust and the moralization of purity.

Abstract: Guided by appraisal-based models of the influence of emotion upon judgment, we propose that disgust moralizes—that is, amplifies the moral significance of—protecting the purity of the body and soul. Three studies documented that state and trait disgust, but not other negative emotions, moralize the purity moral domain but not the moral domains of justice or harm/care. In Study 1, integral feelings of disgust, but not integral anger, predicted stronger moral condemnation of behaviors violating purity. In Study 2, experimentally induced disgust, compared with induced sadness, increased condemnation of behaviors violating purity and increased approval of behaviors upholding purity. In Study 3, trait disgust, but not trait anger or trait fear, predicted stronger condemnation of purity violations and greater approval of behaviors upholding purity. We found that, confirming the domain specificity of the disgust–purity association, disgust was unrelated to moral judgments about justice (Studies 1 and 2) or harm/care (Study 3). Finally, across studies, individuals of lower socioeconomic status (SES) were more likely than individuals of higher SES to moralize purity but not justice or harm/care.

The relations between parents' Big Five personality factors and parenting: a meta-analytic review

Abstract: To investigate the association between Big Five personality factors and three dimensions of parenting-warmth, behavioral control, and autonomy support-the authors conducted meta-analyses using 5,853 parent-child dyads that were included in 30 studies. Effect sizes were significant and robust across mother and father reports and across assessment methods of parenting (self-report versus observations) but were generally small in magnitude. Higher levels of Extraversion, Agreeableness, Conscientiousness, and Openness and lower levels of Neuroticism were related to more warmth and behavioral control, whereas higher levels of Agreeableness and lower levels of Neuroticism were related to more autonomy support. Several factors moderated the relationship between specific personality dimensions and parenting: child and parental age, reliability of observational assessment of parenting behavior, and study design. Taken together, these results indicate that personality can be seen as an inner resource that affects parenting.

Moral typecasting: divergent perceptions of moral agents and moral patients.

Abstract: Moral agency is the capacity to do right or wrong, whereas moral patiency is the capacity to be a target of right or wrong. Through 7 studies, the authors explored moral typecasting-an inverse relation between perceptions of moral agency and moral patiency. Across a range of targets and situations, good- and evil-doers (moral agents) were perceived to be less vulnerable to having good and evil done to them. The recipients of good and evil (moral patients), in turn, were perceived as less capable of performing good or evil actions. Moral typecasting stems from the dyadic nature of morality and explains curious effects such as people's willingness to inflict greater pain on those who do good than those who do nothing.

Embodiment of emotion concepts.

Abstract: Theories of embodied cognition hold that higher cognitive processes operate on perceptual symbols and that concept use involves partial reactivations of the sensory-motor states that occur during experience with the world. On this view, the processing of emotion knowledge involves a (partial) reexperience of an emotion, but only when access to the sensory basis of emotion knowledge is required by the task. In 2 experiments, participants judged emotional and neutral concepts corresponding to concrete objects (Experiment 1) and abstract states (Experiment 2) while facial electromyographic activity was recorded from the cheek, brow, eye, and nose regions. Results of both studies show embodiment of specific emotions in an emotion-focused but not a perceptual-focused processing task on the same words. A follow up in Experiment 3, which blocked selective facial expressions, suggests a causal, rather than simply a correlational, role for embodiment in emotion word processing. Experiment 4, using a property generation task, provided support for the conclusion that emotions embodied in conceptual tasks are context-dependent situated simulations rather than associated emotional reactions. Implications for theories of embodied simulation and for emotion theories are discussed.

Collective narcissism and its social consequences.

Abstract: This article introduces the concept of collective narcissism--an emotional investment in an unrealistic belief about the in group's greatness--aiming to explain how feelings about an ingroup shape a tendency to aggress against outgroups. The results of 5 studies indicate that collective, but not individual, narcissism predicts intergroup aggressiveness. Collective narcissism is related to high private and low public collective self-esteem and low implicit group esteem. It predicts perceived threat from outgroups, unwillingness to forgive outgroups, preference for military aggression over and above social dominance orientation, right-wing authoritarianism, and blind patriotism. The relationship between collective narcissism and aggressiveness is mediated by perceived threat from outgroups and perceived insult to the ingroup. In sum, the results indicate that collective narcissism is a form of high but ambivalent group esteem related to sensitivity to threats to the ingroup's image and retaliatory aggression.

Proscriptive versus prescriptive morality: two faces of moral regulation.

Abstract: A distinction is made between two forms of morality on the basis of approach-avoidance differences in self-regulation. Prescriptive morality is sensitive to positive outcomes, activation-based, and focused on what we should do. Proscriptive morality is sensitive to negative outcomes, inhibition-based, and focused on what we should not do. Seven studies profile these two faces of morality, support their distinct motivational underpinnings, and provide evidence of moral asymmetry. Both are well-represented in individuals' moral repertoire and equivalent in terms of moral weight, but proscriptive morality is condemnatory and strict, whereas prescriptive morality is commendatory and not strict. More specifically, in these studies proscriptive morality was perceived as concrete, mandatory, and duty-based, whereas prescriptive morality was perceived as more abstract, discretionary, and based in duty or desire; proscriptive immorality resulted in greater blame, whereas prescriptive morality resulted in greater moral credit. Implications for broader social regulation, including cross-cultural differences and political orientation, are discussed.

Inequality, discrimination, and the power of the status quo: Direct evidence for a motivation to see the way things are as the way they should be.

Abstract: How powerful is the status quo in determining people's social ideals? The authors propose (a) that people engage in injunctification, that is, a motivated tendency to construe the current status quo as the most desirable and reasonable state of affairs (i.e., as the most representative of how things should be); (b) that this tendency is driven, at least in part, by people's desire to justify their sociopolitical systems; and (c) that injunctification has profound implications for the maintenance of inequality and societal change. Four studies, across a variety of domains, provided supportive evidence. When the motivation to justify the sociopolitical system was experimentally heightened, participants injunctified extant (a) political power (Study 1), (b) public funding policies (Study 2), and (c) unequal gender demographics in the political and business spheres (Studies 3 and 4, respectively). It was also demonstrated that this motivated phenomenon increased derogation of those who act counter to the status quo (Study 4). Theoretical implications for system justification theory, stereotype formation, affirmative action, and the maintenance of inequality are discussed.

Social exclusion and early-stage interpersonal perception: Selective attention to signs of acceptance.

Abstract: Social exclusion can thwart people's powerful need for social belonging. Whereas prior studies have focused primarily on how social exclusion influences complex and cognitively downstream social outcomes (e.g., memory, overt social judgments and behavior), the current research examined basic, early-in-the-cognitive-stream consequences of exclusion. Across 4 experiments, the threat of exclusion increased selective attention to smiling faces, reflecting an attunement to signs of social acceptance. Compared with nonexcluded participants, participants who experienced the threat of exclusion were faster to identify smiling faces within a "crowd" of discrepant faces (Experiment 1), fixated more of their attention on smiling faces in eye-tracking tasks (Experiments 2 and 3), and were slower to disengage their attention from smiling faces in a visual cueing experiment (Experiment 4). These attentional attunements were specific to positive, social targets. Excluded participants did not show heightened attention to faces conveying social disapproval or to positive nonsocial images. The threat of social exclusion motivates people to connect with sources of acceptance, which is manifested not only in "downstream" choices and behaviors but also at the level of basic, early-stage perceptual processing.

Maturation of personality in adolescence

Abstract: The present research assesses adolescent personality maturation by examining 3 measures of change and stability (i.e., mean-level change, rank-order stability, and profile similarity) of Big Five personality traits, employing data from a 5-annual-wave study with overlapping early to middle (n = 923) and middle to late (n = 390) adolescent cohorts. Results indicated that mean levels of Agreeableness and Emotional Stability increased during adolescence. There was mixed evidence for increases in Extraversion and Openness. Additionally, rank-order stability and profile similarity of adolescent personality traits clearly increased from early to late adolescence. For all change facets, the authors found evidence for gender differences in the timing of adolescent personality maturation, as girls were found to mature earlier than boys.

Predicting actual behavior from the explicit and implicit self-concept of personality.

Abstract: The authors present a behavioral process model of personality that specifies explicit and implicit aspects of the self-concept of personality as predictors of actual behavior. An extensive behavioral study (N = 130) including a variety of relevant social situations was conducted. This approach allowed reliable measurement of more than 50 behavioral indicators. A priori assignment of indicators to the Big Five dimensions was conducted on the basis of theory and expert ratings. In line with the authors' model, 3 main findings were revealed: First, direct measures (questionnaires) of personality predicted actual behavior for all Big Five dimensions. Second, indirect measures (implicit association tests) of neuroticism and extraversion also predicted actual behavior. Third, the predictive validity of these indirect measures was incremental. The authors were additionally able to show that controlling for valence did not affect any of these results. Implications and future prospects for the study of personality and actual behavior are discussed.

Aggress to impress: hostility as an evolved context-dependent strategy.

Abstract: Given the high costs of aggression, why have people evolved to act aggressively? Comparative biologists have frequently observed links between aggression, status, and mating in nonhuman animals. In this series of experiments, the authors examined the effects of status, competition, and mating motives on men’s and women’s aggression. For men, status motives increased direct aggression (face-to-face confrontation). Men’s aggression was also boosted by mating motives, but only when observers were other men. For women, both status and mating motives increased indirect aggression (e.g., socially excluding the perpetrator). Although neither status nor mating motives increased women’s direct aggression, women did become more directly aggressive when motivated to compete for scarce resources. These context- and sex-specific effects on human aggression contribute to a broader understanding of the functional nature of aggressive behavior.
