Kindergarten self-control mediates the gender reading achievement gap: A population-based cohort study

Could superior self-control explain the gender difference in reading achievement favoring girls? To test this idea, we drew on a unique population-based sample (N = 11,336) where self-control was measured in kindergarten using a multimethod battery of assessments. Girls showed substantially higher levels of self-control in kindergarten (β = 0.47) and outperformed boys on standardized tests of reading achievement in third/fourth grade (β = 0.20). Further, kindergarten self-control prospectively predicted reading achievement throughout elementary school (β = 0.37). Connecting these findings, our mediation analyses revealed that the female self-control advantage in kindergarten could account for subsequent gender differences in reading achievement. Our results suggest that early gender differences in self-control may represent a key pathway through which gender disparities in reading skills, vocabulary knowledge, and reading comprehension occur.     

Brief report: Complex postformal thought in skilled research administrators

Expert research administrators responded to questions to determine to what degree they had postformal thinking skills. Postformal theory suggests that the interpersonal and institutional complexity of work roles would make them likely to exhibit postformal thought. The tests included a questionnaire about the use of postformal operations on the job, and thinking-aloud taped interviews of responses to job-related and standard postformal problems. The respondents demonstrated the use of postformal thinking operations on job-related tests and a more moderate degree of use on the standard problems. The results support prior research and our working hypothesis that a high degree of interaction with people and complex problems is associated with adults' postformal thought.     

Larger reported impact of stuttering in teenage females,compared to males – A comparison of teenagers’ result on Overall Assessment of the Speaker’s Experience of Stuttering (OASES)

PurposeThe aim of this cross-sectional study was to explore the impact and experience of stuttering, and attitude to communication for female and male teenagers who stutter (TWS) in comparison with teenagers with no stutter (TWNS).MethodsThe Swedish version of the Overall Assessment of the Speaker’s Experience of Stuttering (OASES-T-S), was administered to 56 TWS, 13–17 years old (26 females, 30 males). An adapted version of OASES, Attitude to Speech and Communication (ASC), was administered to 233 TWNS. The impact scores were analyzed in relation to sex in TWS and TWNS.ResultsFemale TWS reported that stuttering had a greater impact on their life than it did on male TWS (on average 0.5 higher impact scores; Hedges’ g = 0.87). The differences did not seem to be caused by differences in severity of overt stuttering symptoms. Female and male TWS particularly differed on items related to difficulties in day-to-day communication and affective/behavioral reactions to stuttering. Such sex differences were not as pronounced among TWNS, suggesting that teenage women may be more vulnerable to the negative impact of stuttering than men the same age.ConclusionFemale teenagers report more negative experiences and a greater tendency to use avoidance strategies than male teenagers.     

Investigating sex,masculinity and femininity in relation to impulsive driving and driving anger expression

Human factors constitute a class of prominent road safety related factors. In the present study, human factors of driving were studied by investigating sex differences and gender roles in relation to impulsive driving and driving anger expression. A total of 425 drivers between the ages of 18 and 56 (M = 25.46, SD = 7.58) participated to the study and completed a series of questionnaires including a demographic information form, the Bem Sex Roles Inventory, the Impulsive Driver Behaviour Scale and the Driving Anger Expression Inventory. According to the ANCOVA results, male drivers showed higher functional impulsivity, lack of premeditation and use of the vehicle to express anger than female drivers. Additionally, hierarchical regression analyses showed that masculinity was positively associated with functional impulsivity, urgency and the dimensions of aggressive anger expression. However, femininity was positively associated with functional impulsivity and adaptive/constructive anger expression, but negatively associated with the dimensions of dysfunctional impulsivity and aggressive anger expression. Overall, the results showed the significant solo effects of masculinity and femininity on impulsive driver behaviours and driving anger expression, over and above the effects of sex, and the interaction between sex and gender roles. In the present study, previously reported findings indicating the relationships between sex and gender roles and driving anger expression were supported and extended by providing the literature with the contribution of answering the question how sex and gender roles are related to impulsive driver behaviours. The findings of the two related concepts of impulsive driving and driving anger expression were discussed in light of the current literature. Contributions, implications and future research directions concerning road safety practices were presented.     

Bullying as a group process: Participant roles and their relations to social status within the group

Bullying was investigated as a group process, a social phenomenon taking place in a school setting among 573 Finnish sixth-grade children (286 girls, 287 boys) aged 12–13 years. Different Participant Roles taken by individual children in the bullying process were examined and related to a) self-estimated behavior in bullying situations, b) social acceptance and social rejection, and c) belongingness to one of the five sociometric status groups (popular, rejected, neglected, controversial, and average). The Participant Roles assigned to the subject were Victim, Bully, Reinforcer of the bully, Assistant of the bully, Defender of the victim, and Outsider. There were significant sex differences in the distribution of Participant Roles. Boys were more frequently in the roles of Bully, Reinforcer and Assistant, while the most frequent roles of the girls were those of Defender and Outsider. The subjects were moderately well aware of their Participant Roles, although they underestimated their participation in active bullying behavior and emphasized that they acted as Defenders and Outsiders. The sociometric status of the children was found to be connected to their Participant Roles. © 1996 Wiley-Liss, Inc.     

Aggressive behavior in the free-ranging rhesus monkeys of kathmandu,nepal

We present a composite sample of the aggressive behavior of free-ranging rhesus monkeys (Macaca mulatta), recorded at two temples in Kathmandu, Nepal. We analyze the total number and the rate per monkey of threats, chases, attacks, fights, and aggressive acts directed at other species (principally humans), in order to elucidate social dynamics of the troop as a whole. Our 1,506 hours of observation were divided among the four seasons; between a.m. and p.m.; and among a temple yard, two parklands, and a forested garden. We found seasonal patterns to be the most important correlates of aggressive behavior. Habitat was a modulating influence, and time of day was the least important factor. Rates of aggression were generally higher per male monkey than per female. In terms of total aggression recorded, however, females instigated significantly more than males, both in encounters between monkeys and in aggression against other species. This finding is consistent with the females' greater numbers in the troop and with their lifelong membership in the troop. Analysis of behavior by social groups, rather than by individual rates, points up the iomportance of adult females and their social stability in troop behavior.     

Female and male soccer players recruited different cognitive processes when generating creative soccer moves

Previous research has indicated that in several domains, women and men may use different cognitive processes along with different neurophysiological activation to achieve similar behavioral performance. The present study extended this line of research to the novel field of soccer playing. In female and male active soccer players, we investigated patterns of brain activation and functional connectivity of brain networks during imagination of creative soccer moves, using EEG methods that are well established in creativity research. Participants were presented with scenarios taken from real soccer games. Female and male soccer players showed comparable creative performance in their imagined moves to score a goal, which was rated by top qualified experts (UEFA A licensed soccer coaches). Notwithstanding, they differed with respect to their brain activation and functional connectivity of brain networks. While men exhibited relatively higher parietal/occipital task-related EEG alpha power, women showed significantly higher within-hemisphere functional coupling in the upper alpha band. The findings add important new evidence to the field of cognitive gender research in an applied, sports-related domain of creative cognition.     

恐惧记忆习得与消退的性别差异及其神经机制

大多数人在其一生中都会经历创伤事件,但只有少数人会发展成为创伤后应激障碍（PTSD）。焦虑障碍的易感性和保护因素成为一个重要议题。基于恐惧记忆习得与消退模型的研究发现女性个体表现出“易习得、难消退”的特点。在恐惧相关脑区的脑生理结构、功能/结构连接性、以及大脑可塑性的性别差异可能是该特征的根本原因。性激素作为一种焦虑障碍的保护因素,可以调节这种性别差异,这种调节效应可能是通过影响大脑结构形态（如神经细胞的形态和数量）、调控与记忆相关基因的表达（如HDAC4）而实现的。雌性激素水平的不稳定性可能是女性易感焦虑障碍的重要原因。未来对性别差异的深入研究将有助于推进个性化医疗。
