The Effects of Individual Differences and Charismatic Leadership on Workplace Aggression.

This study examined the effects of individual differences variables (trait anger, self-control, negative affectivity, attitudes toward revenge, and attributional style) and charismatic leadership on incidents of workplace aggression in a sample of 213 employees from a wide range of organizations. Hierarchical multiple regression analyses indicated that the individual differences variables accounted for 27% of the variance in workplace aggression and that charismatic leadership accounted for an additional 3% after controlling for individual differences. In addition, psychological empowerment partially mediated the relationship between charismatic leadership and workplace aggression. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Sex Differences in Aggression in Real-World Settings: A Meta-Analytic Review.

Meta-analytic reviews of sex differences in aggression from real-world settings are described. They cover self-reports, observations, peer reports, and teacher reports of overall direct, physical, verbal, and indirect forms of aggression, as well as (for self-reports) trait anger. Findings are related to sexual selection theory and social role theory. Direct, especially physical, aggression was more common in males and females at all ages sampled, was consistent across cultures, and occurred from early childhood on, showing a peak between 20 and 30 years. Anger showed no sex differences. Higher female indirect aggression was limited to later childhood and adolescence and varied with method of measurement. The overall pattern indicated males' greater use of costly methods of aggression rather than a threshold difference in anger. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Jealousy and the threatened self: Getting to the heart of the green-eyed monster.

Several theories specifying the causes of jealousy have been put forth in the past few decades. Firm support for any proposed theory, however, has been limited by the difficulties inherent in inducing jealousy and examining any proposed mediating mechanisms in real time. In support of a theory of jealousy centering on threats to the self-system, 2 experiments are presented that address these past limitations and argue for a model based on context-induced variability in self-evaluation. Experiment 1 presents a method for evoking jealousy through the use of highly orchestrated social encounters and demonstrates that threatened self-esteem functions as a principal mediator of jealousy. In addition to replicating these findings, Experiment 2 provides direct evidence for jealousy as a cause of aggression. The ability of the proposed theory of jealousy to integrate other extant findings in the literature is also discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Sex Differences and Individual Differences in Cognitive Performance and Their Relationship to Endogenous Gonadal Hormones and Gonadotropins.

Sexually dimorphic cognitive performance in men (n=42) and women (n=42) was related to testosterone, estradiol, progesterone, luteinizing hormone, follicle-stimulating hormone, and sex hormone binding globulin, measured in 10-ml blood samples collected between 0900 and 1030 and, among women, during the follicular phase of the menstrual cycle. Significant sex differences favored men on spatial tasks (Mental Rotation and Judgment of Line Orientation) and on an inhibition task and favored women on a verbal task (category fluency). However, there were no significant relationships between any of the hormones and cognitive performance, suggesting that there are few, if any, consistent, substantial relationships between endogenous, nonfluctuating levels of gonadal hormones or gonadotropins and these cognitive abilities in men or women.

Husbands' and Wives' Marital Adjustment, Verbal Aggression, and Physical Aggression as Longitudinal Predictors of Physical Aggression in Early Marriage.

Marital adjustment, verbal aggression, and physical aggression have long been associated in the marital literature, but the nature of their associations remains unclear. In this study, the authors examined these 3 constructs as risk factors for physical aggression during the first 2 years of marriage in 634 couples recruited as they applied for marriage licenses. Couples completed assessments at the time of marriage and at their 1st and 2nd anniversaries. Results of path analyses suggest that prior verbal aggression and physical aggression by both partners are important longitudinal predictors of physical aggression but do not support the role of marital adjustment as a unique predictor of subsequent physical aggression. Contrary to prior research, results also failed to support physical aggression as a unique predictor of marital adjustment. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Individual Differences and Cross-Situational Consistency of Dyadic Social Behavior.

A new theoretical analysis of individual differences and cross-situational consistency of behavior is proposed. The authors hypothesized that the social behavior of mice (Mus musculus) is determined by individual differences among animals in behavior emitted (i.e., actor effects), in behavior elicited from social partners (partner effects), and by unique responses of one animal to another (relationship effects). Each effect represents a distinct facet of individual differences with different psychological meaning; likewise, the cross-situational consistency of each effect has a distinct psychological meaning. Individual differences in behavior emitted were observed, and these actor effects were consistent longitudinally. Individual differences in behavior elicited from social partners were observed, and these partner effects were also consistent longitudinally. Unique responses to specific social partners also determined behavior but were inconsistent longitudinally. The theoretical importance of reconceptualizing the concepts of individual differences and cross-situational consistency in behavior is discussed.

Understanding Supervisor-Targeted Aggression: A Within-Person, Between-Jobs Design.

The authors investigated predictors of supervisor-targeted workplace aggression among 105 "moonlighters" (employed adults who work 2 jobs, each with a different supervisor), as a way of examining the relative role played by within-subject situational differences and between-subjects individual differences. Individual difference variables (self-esteem, history of aggression) explained a similar level of variance in aggression across both jobs, whereas situational factors (interactional injustice, abusive supervision) were job specific and explained proportionally more variance than did individual differences.

"I'm OK but You're Not" and Other Peer-Relational Schemas: Explaining Individual Differences in Children's Social Goals.

This study examined the links among 5th and 6th graders' (279 girls and 310 boys) self- and peer perceptions, social goals, and social behavior. Social goals mediated the effects of self- and peer perceptions on 3 types of behavior: proactive aggression, prosocial behavior, and withdrawal. In addition to their main effects (self-perception predicting variance in agentic goals, peer perception being related to communal goals), self- and peer perception interacted in influencing social goals; for instance, the effects of a positive view of oneself were different in the contexts of a positive versus a negative perception of peers. It is suggested that in order to predict children's social behavior more accurately, researchers should investigate children's dual perceptions of themselves and of their peers--that is, their peer-relational schemas--instead of assessing self-perception and peer perception in isolation from each other.

Age Trends in the Development of Aggression, Sex Typing, and Related Television Habits: Correction.

Reports an error in the original article by L. D. Eron et al ("Age Trends in the Development of Aggression, Sex Typing, and Related Television Habits," Developmental Psychology, 1983, Vol. 19, No. 1, pp. 71-77). There is an incorrect statement in the first full paragraph of the left column on page 76. The correct statement is listed. Two typographical errors are also noted. (The following abstract of this article originally appeared in record 1983-07714-001): Conducted a 3-yr longitudinal study with 2 large samples of elementary school youngsters overlapping in 1 grade (N = 672, 607, and 505 for each successive year). It was thus possible to trace developmental trends from Grades 1 to 5 on the following variables: aggression, frequency of TV viewing, extent of violence viewed on TV, judged realism of TV programs, and preference for masculine, feminine, or neutral activities. Data support the theory that there is a sensitive period during which the effect of TV can be especially influential on children's behavior. Further, since the correlation between violence viewing and aggression tends to increase until age 10-21 yrs, a cumulative effect beyond the sensitive period is suggested.

"The Effect of Experimentally Induced Failure, Self-Esteem, and Sex on Cognitive Differentiation": Errata.

Reports errors in the original article by R. Cruz Perez (Journal of Abnormal Psychology, 1973[Feb], 81[1], 74-79). On Table 2, the numbers for the low self-esteem failure females for the before and after columns, respectively, should be 611.00 and 625.12. The numbers for the low self-esteem control females for the before and after columns, respectively, should be 484.00 and 463.87. (The following abstract of this article originally appeared in record 1973-21060-001.) Investigated the effect of experimentally-induced failure upon an immediately-following cognitive differentiation task, on the hypothesis that these effects are differentially mediated by self-esteem and sex variables. 32 male and 32 female undergraduates completed the Coopersmith Self-Esteem Inventory and the Embedded Figures Test (EFT). Ss were then given Raven's Progressive Matrices under time-limit failure or control conditions, and were retested on the EFT. Results support the hypothesis that after the experience of failure, high-esteem Ss would work faster and low-esteem Ss would work slower on the EFT retest. An additional hypothesis that males would work faster than females on the EFT was supported only for the low self-esteem females. Implications of these findings are explored. (25 ref.)

Savoring Versus Dampening: Self-Esteem Differences in Regulating Positive Affect.

Five studies examined the hypotheses that when people experience positive affect, those low in self-esteem are especially likely to dampen that affect, whereas those high in self-esteem are especially likely to savor it. Undergraduate participants' memories for a positive event (Study 1) and their reported reactions to a success (Study 2) supported the dampening prediction. Results also suggest that dampening was associated with worse mood the day after a success (Study 2), that positive and negative affect regulation are distinct, that self-esteem is associated with affect regulation even when Neuroticism and Extraversion are controlled (Studies 3 and 4), and that self-esteem may be especially important for certain types of positive events and positive affect regulation (Study 5).

Individual differences in judging deception: Accuracy and bias.

The authors report a meta-analysis of individual differences in detecting deception, confining attention to occasions when people judge strangers' veracity in real-time with no special aids. The authors have developed a statistical technique to correct nominal individual differences for differences introduced by random measurement error. Although researchers have suggested that people differ in the ability to detect lies, psychometric analyses of 247 samples reveal that these ability differences are minute. In terms of the percentage of lies detected, measurement-corrected standard deviations in judge ability are less than 1%. In accuracy, judges range no more widely than would be expected by chance, and the best judges are no more accurate than a stochastic mechanism would produce. When judging deception, people differ less in ability than in the inclination to regard others' statements as truthful. People also differ from one another as lie- and truth-tellers. They vary in the detectability of their lies. Moreover, some people are more credible than others whether lying or truth-telling. Results reveal that the outcome of a deception judgment depends more on the liar's credibility than any other individual difference. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Review of The Causes of Rape: Understanding Individual Differences in Male Propensity for Sexual Aggression.

Reviews the book, The Causes of Rape: Understanding Individual Differences in Male Propensity for Sexual Aggression by Martin L. Lalumière, Grant T. Harris, Vernon L. Quinsey and Marnie E. Rice (see record 2005-00308-000). This text presents an evolutionary explanation for rape, closely related to the writings of people like Wilson and Ellis, with which many readers will be familiar. It develops an argument that rape is a "mating effort" closely associated with "antisociality." If using an evolutionary framework to understand rape does not appeal to you, stop here. But if you are interested in its "sex appeal," this book is interesting. How so? Like other psychobiological writings, it explains the status quo using a carefully selected body of scientific empirical studies that supports their argument... And, overlooking some shortcomings, it does it well! (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Review of The uncertain mind: Individual differences in facing the unknown.

Reviews the book, The uncertain mind: Individual differences in facing the unknown by Richard M. Sorrentino and Christopher J. R. Roney (see record 2000-07377-000). The book under review is located within an important intellectual tradition in psychology, one that speaks to something about human nature. Sorrentino and Roney approach this topic through the study of individual differences in whether people seek out certainty or uncertainty in their lives. While some of us find meaning in terms of the familiar and predictable, others search for meaning in the novel uncertainties of life. This scholarly monograph describes a 15-year program of research, theoretically grounded in both earlier paradigms (e.g., Atkinson's motivational model) and contemporary social cognition. This monograph merits attention by researchers and students interested in social cognition, individual differences, and societal change. The writing is technical, and one would wish for chapter summaries. However, the book is clearly written, well-organized and at times thought-provoking; it is well worth the effort.

Mismatches in Social Support and Psychosocial Adjustment to Breast Cancer.

Emotional support is known to provide psychosocial benefits for women with breast cancer, but women can experience a mismatch between support that is wanted and support that is received from their personal supporter. The role of wanted and unwanted support in psychosocial adjustment was examined in 79 women recovering from breast cancer. Four distinct patterns of desired support actions were found using cluster analysis. Patterns of wanted support were not related to better or worse psychosocial adjustment. However, a misalignment of support between the provider and the receiver significantly influenced psychosocial adjustment, and unwanted but received support (support commission) was uniquely associated with poor psychosocial adjustment. Clinical interventions using the support instrument could help match support providers' actions to receivers' preferences. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Individual Differences in Sensitivity to Health Communications: Consideration of Future Consequences.

There are reliable individual differences in the extent to which people consider the long- and short-term consequences of their behaviors. Such differences, assessed by the Consideration of Future Consequences (CFC) Scale (A. Strathman, F. Gleicher, D. S. Boninger, & C. S. Edwards, 1994), are hypothesized to influence the impact of a persuasive communication. In an experimental study, the time frame of occurrence of positive and negative consequences of engaging in a new colorectal cancer-screening program was manipulated in a sample of two hundred twenty 50-69-year-old men and women. CFC moderated (a) the processing of short- versus long-term consequences and (b) the persuasive impact of the different communications on behavioral intentions. Low CFC individuals produced more positive thoughts and were more persuaded when positive consequences were short term and negative consequences were long term. The opposite was true for high CFC individuals. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Individual Differences in Absolute and Relative Metacomprehension Accuracy.

The authors investigated absolute and relative metacomprehension accuracy as a function of verbal ability in college students. Students read hard texts, revised texts, or a mixed set of texts. They then predicted their performance, took a multiple-choice test on the texts, and made posttest judgments about their performance. With hard texts, students with lower verbal abilities were overconfident in predictions of future performance, and students with higher verbal abilities were underconfident in judging past performance. Revised texts produced overconfidence for predictions. Thus, absolute accuracy of predictions and confidence judgments depended on students' abilities and text difficulty. In contrast, relative metacomprehension accuracy as measured by gamma correlations did not depend on verbal ability or on text difficulty. Absolute metacomprehension accuracy was much more dependent on types of materials and verbal skills than was relative accuracy, suggesting that they may tap different aspects of metacomprehension.

The moderating roles of self-esteem and neuroticism in the relationship between group and individual undermining behavior.

The authors developed and tested a multilevel interactive model of the relationship between group undermining and individual undermining behavior in 2 multiwave studies of group members. Integrating the literature on group influences on individual behavior with the individual difference literature, the authors predicted a 3-way Group Undermining × Self-Esteem × Neuroticism interaction, such that the relationship between group and individual undermining would be strongest among those simultaneously high in self-esteem and neuroticism. The 3-way interaction was supported in Study 1 (457 participants in 103 groups) and replicated in Study 2 (415 participants in 93 groups) with additional controls and alternative measures of key constructs. The authors discuss the implications of the research and identify future research directions. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Sex differences in cooperation: A meta-analytic review of social dilemmas.

Although it is commonly believed that women are kinder and more cooperative than men, there is conflicting evidence for this assertion. Current theories of sex differences in social behavior suggest that it may be useful to examine in what situations men and women are likely to differ in cooperation. Here, we derive predictions from both sociocultural and evolutionary perspectives on context-specific sex differences in cooperation, and we conduct a unique meta-analytic study of 272 effect sizes—sampled across 50 years of research—on social dilemmas to examine several potential moderators. The overall average effect size is not statistically different from zero (d = –0.05), suggesting that men and women do not differ in their overall amounts of cooperation. However, the association between sex and cooperation is moderated by several key features of the social context: Male–male interactions are more cooperative than female–female interactions (d = 0.16), yet women cooperate more than men in mixed-sex interactions (d = –0.22). In repeated interactions, men are more cooperative than women. Women were more cooperative than men in larger groups and in more recent studies, but these differences disappeared after statistically controlling for several study characteristics. We discuss these results in the context of both sociocultural and evolutionary theories of sex differences, stress the need for an integrated biosocial approach, and outline directions for future research.
