Narcissism moderates the association between basal testosterone and generosity in men.

Research has linked hormones to behavioral outcomes in intricate ways, often moderated by psychological dispositions. The associations between testosterone and antisocial or prosocial outcomes also depend on dispositions relevant to status and dominance. In two studies (N1 = 68, N2 = 83), we investigated whether endogenous testosterone, measured in saliva, and narcissism, a psychological variable highly relevant to status motivation, interactively predicted men's preferences regarding resource allocation. Narcissism moderated the links between testosterone and social value orientation: among low narcissists testosterone negatively predicted generosity in resource allocation and probability of endorsing a prosocial (vs. pro-self) value orientation, whereas among high narcissists testosterone tended to positively predict generosity and the probability of endorsing a prosocial (vs. pro-self) value orientation. We discuss these results as examples of calibrating effects of testosterone on human behavior, serving to increase and maintain social status. We advocate the relevance of psychological dispositions, alongside situations, when examining the role of T in social outcomes.

Communal collective narcissism.

OBJECTIVES: We aimed to introduce, validate, and showcase the utility of a new construct: communal collective narcissism. METHOD: We conducted four studies, in which we developed a new scale for communal collective narcissism (Study 1, N = 856), tested the construct's unique predictions (Study 2, N = 276), examined its social relevance (Study 3, N = 250), and assessed its implications for intergroup outcomes (Study 4, N = 664). RESULTS: In Study 1, we verified the structural soundness of the Communal Collective Narcissism Inventory. In Study 2, we obtained evidence for a defining feature of communal collective narcissism, namely, that it predicts communal, but not agentic, ingroup-enhancement. In Study 3, we illustrated the social relevance of communal collective narcissism. Communal collective narcissists derogated outgroup members, if those outgroups threatened the ingroup and the threat targeted the ingroup's communion. Finally, in Study 4, we showed that communal collective narcissism predicts intergroup outcomes in the communal domain (e.g., humanitarian aid) better than agentic collective narcissism does, whereas agentic collective narcissism predicts intergroup outcomes in the agentic domain (i.e., preferences for military aggression) better than communal collective narcissism does. CONCLUSIONS: The construct of communal collective narcissism is conceptually and empirically distinct from classic (i.e., agentic) collective narcissism.

What do highly narcissistic people think and feel about (their) intelligence?

OBJECTIVE: The current research comprehensively examined how grandiose and vulnerable narcissism are linked to intelligence and intelligence-related beliefs and emotions. METHOD: In four studies (total N = 1,141), we tested the associations between both forms of narcissism, subjectively and objectively assessed intelligence, basic personality traits, test-related stress, beliefs about intelligence, and well-being. RESULTS: Both forms of narcissism (grandiose and vulnerable) were unrelated to objective intelligence. Grandiose narcissism was associated with high self-perceived intelligence (Studies 1-3) and explained more variance in self-perceived intelligence than objective intelligence and the Big Five personality traits. It was correlated with reduced distress in the context of IQ testing and low engagement in cognitive performance (Study 2). Individuals with high grandiose narcissism based their well-being (Study 3) partly on intelligence and considered intelligence important for success in different life domains, especially for social relations (Study 4). Vulnerable narcissism was unrelated to self-perceived intelligence (Studies 1-3) and went along with increased distress in the context of IQ testing (Study 2). CONCLUSIONS: The results indicate that the topic of intelligence is of key importance for people with high grandiose narcissism psychological functioning and it also has some relevance for individuals with high vulnerable narcissism.

The mental health continuum-short form: The structure and application for cross-cultural studies-A 38 nation study.

OBJECTIVE: The Mental Health Continuum-Short Form (MHC-SF) is a brief scale measuring positive human functioning. The study aimed to examine the factor structure and to explore the cross-cultural utility of the MHC-SF using bifactor models and exploratory structural equation modelling. METHOD: Using multigroup confirmatory analysis (MGCFA) we examined the measurement invariance of the MHC-SF in 38 countries (university students, N = 8,066; 61.73% women, mean age 21.55 years). RESULTS: MGCFA supported the cross-cultural replicability of a bifactor structure and a metric level of invariance between student samples. The average proportion of variance explained by the general factor was high (ECV = .66), suggesting that the three aspects of mental health (emotional, social, and psychological well-being) can be treated as a single dimension of well-being. CONCLUSION: The metric level of invariance offers the possibility of comparing correlates and predictors of positive mental functioning across countries; however, the comparison of the levels of mental health across countries is not possible due to lack of scalar invariance. Our study has preliminary character and could serve as an initial assessment of the structure of the MHC-SF across different cultural settings. Further studies on general populations are required for extending our findings.

Narcissism predicts noise perception but not signal decoding in emotion.

Grandiose narcissists claim that they have better-than-average emotion recognition abilities, but many objective tests do not support this claim. We sought to clarify the relation between grandiose (both agentic and communal) narcissism and emotion recognition by taking a closer look at the components of emotion recognition. In two studies (N1 = 147, N2 = 520), using culturally distinct samples and different stimulus materials, we investigated the relation between grandiose narcissism and signal decoding (accurate view of the intended emotion displayed in an expression) as well as noise perception (inaccurate deciphering of secondary emotions that are not part of the emotional message). Narcissism was inconsistently related to signal decoding, but consistently and positively related to noise perception. High grandiose (agentic and communal) narcissists are not necessarily better at signal decoding, but are more susceptible to noise perception. We discuss implications for narcissists' social interactions and interpersonal relationships.

Higher heart rate variability predicts better affective interaction quality in non-intimate social interactions.

Adaptive emotional responding is crucial for psychological well-being and the quality of social interactions. Resting heart rate variability (HRV), a measure of autonomic nervous system activity, has been suggested to index individual differences in emotion regulation (ER). As non-intimate social interactions require more regulatory efforts than intimate social interactions, we predicted that the association between HRV and affective interaction quality is moderated by the perceived intimacy of the exchange. Thus, we expected higher HRV to be particularly beneficial for affective interaction quality in non-intimate social interactions. Resting HRV was measured in the laboratory (N = 144). Subsequently, participants reported their affective interaction quality-as indicated by more positive and fewer negative emotions perceived in the self and the other-during an experience-sampling social interaction diary task. As predicted, in non-intimate interactions, individuals with higher HRV reported more positive and fewer negative emotions and perceived fewer negative emotions in their interaction partners. The results provide further insights into the relationship between HRV and emotional experiences during social interactions.

The Dirty Dozen Scale: Validation of a Polish Version and Extension of the Nomological Net.

In five studies (total N = 1300) we developed and validated a Polish version of the Dirty Dozen measure (DTDD-P) that measures the three traits of the Dark Triad, Machiavellianism, psychopathy, and narcissism. We detail the presence and stability of a bifactor structure of the 12 items and present evidence for good internal consistency and test-retest reliability. We examine the nomological network surrounding the Dark Triad and show that both the Dark Triad total score and the subscales have acceptable validity. We also present evidence on the Dark Triad and moral behavior. Dark Triad predicts utilitarian moral choice (e.g., approval for sacrificing somebody's life for the sake of saving others) and this link is mediated by low empathic concern. In total, our results suggest that the Polish Dirty Dozen-Parszywa Dwunastka-is valid, stable, and useful for the study of lingering puzzles in the literature.

Do Narcissism and Emotional Intelligence Win Us Friends? Modeling Dynamics of Peer Popularity Using Inferential Network Analysis.

This research investigated effects of narcissism and emotional intelligence (EI) on popularity in social networks. In a longitudinal field study, we examined the dynamics of popularity in 15 peer groups in two waves ( N = 273). We measured narcissism, ability EI, and explicit and implicit self-esteem. In addition, we measured popularity at zero acquaintance and 3 months later. We analyzed the data using inferential network analysis (temporal exponential random graph modeling, TERGM) accounting for self-organizing network forces. People high in narcissism were popular, but increased less in popularity over time than people lower in narcissism. In contrast, emotionally intelligent people increased more in popularity over time than less emotionally intelligent people. The effects held when we controlled for explicit and implicit self-esteem. These results suggest that narcissism is rather disadvantageous and that EI is rather advantageous for long-term popularity.

Do I Mirror Your Mood if We're Peas in a Pod? Similarity and Liking in the Social Induction of Affect.

The present study investigates whether similarity in personality traits between a sender displaying affect and a receiver observing it influences the social induction of affect. We hypothesized that exposure to a similar sender would foster concordant affective reactions, whereas exposure to a dissimilar sender would foster discordant ones. To induce affect, we used short videos presenting a sender displaying happy versus sad emotional expressions. To manipulate personality similarity, we used a software program to generate brief bogus descriptions of the sender based on the receivers' prior responses to personality items. Our results demonstrated that dissimilarity led to decreased liking and, as a result, reduced the tendency to react with concordant affect to a happy sender's emotional expression. However, we found no evidence supporting the induction of discordant affective reactions.

Individual differences in response to uncertainty and decision making: The role of behavioral inhibition system and need for closure.

In two studies, we examined the influence of behavioral inhibition system (BIS) and need for closure (NFC) on information processing in decision making. We expected that BIS would regulate behavior in a decisional context and that this relationship would be mediated by epistemic motivation expressed by NFC. In addition, drawing on contradictory findings in the literature on anxiety, NFC, and information processing, we investigated the moderating role of decision rules. The results supported our predictions. BIS was strongly and positively related to NFC, and through NFC it was related to decision-making style. Moreover, decision task characteristics moderated the relationship between NFC and decision making. When a task did not offer a confident decision rule, high NFC participants prolonged the information search more than low NFC individuals. However, when a reliable strategy was suggested, high NFC participants behaved in line with it. These results are discussed within an uncertainty management framework.

Quick and dirty: some psychosocial costs associated with the Dark Triad in three countries.

The current study provides the first examination of the relationship between life history indicators and the Dark Triad traits in an international sample drawn from the U.S. (n = 264), Singapore (n = 185), and Poland (n = 177). In all three samples, the Dark Triad traits were associated with psychosocial costs, although there were more links in the Singaporean and Polish samples than in the American sample. In the U.S., the quality of one's romantic relationships and psychopathy were negatively correlated. Narcissism was higher in the Polish and American samples than in the Singaporean sample. Men scored higher than women did regardless of location and the sex difference in the individual differences in life histories was mediated by the Dark Triad composite. Results suggest the Dark Triad are related to a volatile socioecology composed of psychosocial costs in the familial, romantic, and platonic relationships.

Are narcissists sexy? Zeroing in on the effect of narcissism on short-term mate appeal.

This research was aimed to provide a comprehensive test of the classic notion that narcissistic individuals are appealing as short-term romantic or sexual partners. In three studies, we tested the hypotheses that narcissism exerts a positive effect on an individual's mate appeal and that this effect is mediated by high physical attractiveness and high social boldness. We implemented a multimethod approach and used ratings of opposite sex persons (Study 1), ratings of friends (Study 2), and records of courtship outcomes in naturalistic interactions (Study 3) as indicators of mate appeal. In all cases, narcissism had a positive effect on mate appeal, which was mainly due to the agentic self-enhancement aspects of narcissism (rather than narcissists' lacking communion). As predicted, physical attractiveness and social boldness mediated the positive effect of narcissism on mate appeal. Findings further indicated that narcissism was more strongly linked to mate appeal than to friend appeal.
