Developmental and Sex Differences in Types of Conduct Problems

Maternal report of types of conduct problems in a high-risk sample of 228 boys and 80 girls (ages 4–18) were examined, using a version of the Child Behavior Checklist, expanded to include a range of covert and overt antisocial items (stealing, lying, physical aggression, relational aggression, substance use, and impulsivity). Age and sex effects were investigated. Boys were significantly more physically aggressive than girls. There were no sex differences for stealing, lying, relational aggression, and substance use. Lying and substance use increased with age, whereas relational aggression and impulsivity peaked during early adolescence. A small group of girls had pervasive conduct problems across multiple domains. For some domains such as stealing, lying, and relational aggression, girls showed at least as many problems as boys. Girls, in general, tended to have fewer conduct problems. On the other hand, when assessed across multiple domains, conduct problems in high-risk girls were possibly more pervasive than in high-risk boys, suggesting the possibility of a gender paradox.     

Foci of attachment in organizations: A meta-analytic comparison of the strength and correlates of workgroup versus organizational identification and commitment

The workgroup and the organization as a whole are common foci of employee attachment (i.e., identification and commitment). This study reviews theorizing and empirical research on the relative impact of attachment to these foci on work attitudes and behavior. Confirming predictions derived from a wide range of previous models, a meta-analysis revealed that (a) on average workgroup attachment is stronger than organizational attachment and (b) each form of attachment is most strongly related to potential outcome variables of the same focus. Practical implications are discussed.     

Think manager—think male,think follower—think female: Gender bias in implicit followership theories

Because of the overlap between the social roles of women and followers, we predicted that people would show a bias, that is, favor female followers over male followers. To support this hypothesis, we conducted two studies: An explicit test of the bias using a scenario design and an implicit association test (IAT)‐based study. Both studies show that the role of an ideal follower is more strongly associated with the female gender role, which seems to be caused partly by a more communal connotation of the follower role. This effect might contribute to the underrepresentation of women in leadership positions as they are perceived to be an ideal fit for followership positions; but it may also push men away from being followers and into leadership positions.     

Role of perceived importance in intergroup contact

Furthering G. W. Allport's contentions for optimal contact, the authors introduce a new construct: the perceived importance of contact. They propose that perceived importance is the best proximal predictor of contact's reduction of prejudice. If individuals have opportunities for contact at work or in the neighborhood, their chances to have intergroup acquaintances and friends increase. Intergroup contact among acquaintances and friends can be perceived as more or less important, which in turn determines intergroup evaluations. A 1st study shows that the new measure of perceived importance is indeed distinct from established quantity and quality indicators. The results are cross-validated in a 2nd study that also sheds light on the meaning of importance. In 3rd and 4th studies, structural equation analyses and a meta-analysis support the hypotheses.     

Which mechanical invariants are associated with the perception of length and heaviness of a nonvisible handheld rod? Testing the inertia tensor hypothesis

It has been suggested that the inertia tensor governs many instances of haptic perception. However, the evidence is inconclusive because other candidate mechanical parameters (i.e., invariants) were not or were insufficiently controlled for in pertinent experiments. By independently varying all candidate mechanical parameters, the authors were able to test the role of the inertia tensor relative to that of other mechanical parameters. The results showed that length perception during rod wielding is not governed by the inertia tensor alone but also by the static moment. In contrast to previous reports, length perception during rod holding and heaviness perception during rod wielding were found to be unrelated to the inertia tensor and strongly related to the static moment.     

On the locus of speed-accuracy trade-off in reaction time: inferences from the lateralized readiness potential

Lateralized readiness potentials (LRPs) were used to determine the stage(s) of reaction time (RT) responsible for speed-accuracy trade-offs (SATs). Speeded decisions based on several types of information were examined in 3 experiments, involving, respectively, a line discrimination task, lexical decisions, and an Erikson flanker task. Three levels of SAT were obtained in each experiment by adjusting response deadlines with an adaptive tracking algorithm. Speed stress affected the duration of RT stages both before and after the start of the LRP in all experiments. The latter effect cannot be explained by guessing strategies, by variations in response force, or as an indirect consequence of the pre-LRP effect. Contrary to most models, it suggests that SAT can occur at a late postdecisional stage.     

Is Neighborhood Context Differently Related to Externalizing Problems and Delinquency for Girls Compared with Boys?

Although a number of reviews of gender differences in conduct problems and delinquency exist, this paper fills a gap in reviewing neighborhood influences on gender differences in conduct problems and delinquency. These influences are known to be important for boys in childhood and adolescence, but cannot be assumed to be influential in the same manner for girls. The paper starts with several conceptualizations of the association between gender, neighborhoods and juvenile delinquency. It then addresses 4 key questions. Is residing in a disadvantaged neighborhood associated with problem behavior in girls? Are neighborhood effects independent of girls' age? Are girls in disadvantaged neighborhoods exposed to more risk factors than girls in advantaged neighborhoods? Can mediating risk factors explain gender differences in neighborhood effects on children's and adolescents' conduct problems and delinquent behavior? Answers to these questions are important to steer research and elucidate aspects of interventions that can be optimized for girls.     

Effects of processing fluency on comparative performance judgments

Research has shown that performance predictions are biased by the impact of processing fluency. However, existing data are inconclusive with regard to comparative judgments of performance. In five experiments, participants in an easy condition gave more favorable comparative judgments than participants in a difficult condition. Participants judged their performance more favorably if they named colors of non-color words rather than non-matching color words (Experiment 1), if they had to generate six words of a category rather than 12 words (Experiment 2), if they had to run in place for 15 s rather than 2 min (Experiment 3), but the latter result holds only true if participants were not active in sports (Experiment 4). When 67% of the items in a recognition test were old words, participants thought that their recognition performance was better than when 33% of the items were old words, although recognition performance did not differ between groups (Experiment 5). We discuss this result in the light of recent theories about effects of processing fluency on judgments.
