Anorexia Nervosa,Major Depression,and Suicide Attempts: Shared Genetic Factors

The extent to which genetic and environmental factors influenced anorexia nervosa (AN), major depressive disorder (MDD), and suicide attempts (SA) were evaluated. Participants were 6,899 women from the Swedish Twin Study of Adults: Genes and Environment. A Cholesky decomposition assessed independent and overlapping genetic and environmental contributions to AN, MDD, and SA. Genetic factors accounted for a substantial amount of liability to all three traits; unique environmental factors accounted for most of the remaining liability. Shared genetic factors may underlie the coexpression of these traits. Results underscore the importance of assessing for signs of suicide among individuals with AN.     

Failure is not an option for Black women: Effects of organizational performance on leaders with single versus dual-subordinate identities

We contribute to a current debate that focuses on whether individuals with more than one subordinate identity (i.e., Black women) experience more negative leader perceptions than do leaders with single-subordinate identities (i.e., Black men and White women). Results confirmed that Black women leaders suffered double jeopardy, and were evaluated more negatively than Black men and White women, but only under conditions of organizational failure. Under conditions of organizational success, the three groups were evaluated comparably to each other, but each group was evaluated less favorably than White men. Further, leader typicality, the extent to which individuals possess characteristics usually associated with a leader role, mediated the indirect effect of leader race, leader gender, and organizational performance on leader effectiveness. Taken together, these results suggest that Black women leaders may carry a burden of being disproportionately sanctioned for making mistakes on the job.     

Threat advantage: Perception of angry and happy dynamic faces across cultures

The current study tested whether the perception of angry faces is cross-culturally privileged over that of happy faces, by comparing perception of the offset of emotion in a dynamic flow of expressions. Thirty Chinese and 30 European-American participants saw movies that morphed an anger expression into a happy expression of the same stimulus person, or vice versa. Participants were asked to stop the movie at the point where they ceased seeing the initial emotion. As expected, participants cross-culturally continued to perceive anger longer than happiness. Moreover, anger was perceived longer in in-group than in out-group faces. The effects were driven by female rather than male targets. Results are discussed with reference to the important role of context in emotion perception.     

Gender and Theory of Mind in Preschoolers’ Group Effort: Evidence for Timing Differences Behind Children’s Earliest Social Loafing

This study explored mental state reasoning within the context of group effort and possible differences in development between boys and girls. Preschool children (59 girls, 47 boys) were assessed for theory of mind (ToM) ability using classic false belief tests. Children participated in group effort conditions that alternated from one condition, where individual effort was transparent and obvious, to one where individual effort remained anonymous. The aim was to investigate if emergent mental state reasoning, after controlling for age, was associated with the well-known phenomenon of reduced effort in group tasks (“social loafing”). Girls had slightly higher ToM scores and social loafing than boys. Hierarchical regression, controlling for age, indicated that understanding of others’ false beliefs uniquely predicted social loafing and interacted weakly with gender status.     

Personality Correlates of Assessment Center Consensus Competency Ratings: Evidence from Russia

Controversy has revolved around whether assessment center ratings have construct validity to measure intended dimensions of managerial performance. In contrast to much recent research on the internal structure of assessment center ratings, the present studies investigated the relationship of final competency ratings derived by consensus discussion with external questionnaire measures of personality characteristics. Expanding on previous studies showing correlations of dimension scores in relation to individual trait measures, this study investigated the relationship of complex competencies with both single personality traits and with composites of personality traits. Evidence from two samples of managers in Russia shows that final competency ratings are related to predicted composites of personality factors more consistently than to single factors. Taken together, these findings provide evidence that assessment center ratings derived by consensus discussion show construct validity in relationship with predicted composites of personality characteristics.     

The Need for an Encyclopedia of Psychological Information

The relationship was examined between judgments of relative distance and judgments of relative size made over a surface on which the packing density of the texture elements was progressively increased, from one end of the surface to the other along the S's line of sight. Significant positive correlations were obtained between distance and size judgments made by 32 Ss. This confirmed a weak version of the size-distance invariance hypothesis and supported a prediction contained in Gibson's theory of space perception.     

Competitive personality attitudes and forgiveness of others

The authors conducted a survey to determine whether competitive attitudes are differentially associated with forgiveness or lack of forgiveness of others. The results showed that hypercompetitiveness was associated with a lack of forgiveness, whereas personal development competitiveness was associated positively with forgiveness. Discussion centers on the need to discourage socialization practices that foster the adoption of a self-contained individualism that is associated with a maladaptive hypercompetitiveness. Instead, parents should promote an ensembled individualism that is associated with a psychologically healthy personal development competitive orientation.     

Adaptive and maladaptive personality traits as predictors of violent and nonviolent offending behavior in men and women

The aim of this study was to assess both violent and nonviolent offending behavior in a single, mixed‐sex population. The rationale for this is that the two types of offending are usually researched separately, despite evidence that they overlap. A comprehensive measure of general violence, intimate partner violence (IPV), and nonviolent offending behavior was administered to 116 men and 181 women, together with measures of personality and personality disorder (PD) traits, to investigate whether predictors of violent and nonviolent offending were similar or different for men and women. Men were found to perpetrate higher levels of general violence and nonviolent offenses than women, but women perpetrated significantly more IPV than men. Cluster B PD traits predicted all three offense types for women and also men's general violence and nonviolent offending. Women's general violence and men's non‐violence also had one unique risk factor each, low agreeableness, and low conscientiousness, respectively. The main difference was for IPV, where men's IPV was predicted by cluster A PD traits, indicating that men's and women's risk factors for IPV may be different, although their risk factors for the other offense types were fairly consistent.

The Effects of Atropine and Adrenergic Antagonists on Behavioral Arousal in Rats

Two experiments investigated the mechanism for changes in measures of behavioral arousal inhibition in rats following administration of atropine. In Experiment 1, 40-day-old rats were given administrations of atropine sulfate, the α-, β-adrenergic blocker labetalol, or both. The drugs, either alone or in combination, increased transport response intensity, whereas both together increased dorsal immobility durations. In Experiment 2, rats were given atropine, the β-adrenergic antagonist propranolol, the α-adrenergic antagonist phentolamine, or a combination of two of the drugs. Propranolol blocked atropine-induced increases in transport response, and phentolamine was without effect. Phentolamine, when combined with atropine, increased dorsal immobility durations. Results are discussed with respect to aspects common to both transport response and dorsal immobility.
