中学生网络利他行为与希望的关系:自我效能感与自尊的中介作用

采用希望特质量表、网络利他行为量表、自尊量表和一般自我效能感量表对326名中学生进行调查, 考察中学生网络利他行为对其希望的影响, 以及自我效能感和自尊在其中的中介作用。结果发现:(1)相关分析显示, 中学生网络利他行为、自我效能感、自尊和希望之间呈显著正相关;(2)结构方程模型分析表明, 自我效能感在中学生网络利他行为对希望的影响中起完全中介作用, 自尊在中学生网络利他行为对希望的影响中不起中介作用, 自我效能感和自尊在中学生网络利他行为对希望的影响中起链式中介作用。     

女性生理周期与修饰行为的关系

众所周知, 与男性相比, 女性偏爱修饰。通过修饰行为, 提升自身吸引力具有普遍的社会意义。近年来, 一些研究者将女性修饰行为与繁殖目的联系起来, 认为女性修饰行为受到生理周期(主要是排卵期和安全期)的影响。具体而言, 排卵期时, 女性的修饰行为会增强, 缘于同性竞争, 包括竞争资源及配偶; 黄体期时, 启动异性吸引动机也会显著增强女性的修饰动机, 目的可能是保持“异性”对自己及后代的持续“投资”。总之, 上述观点为女性持续存在的、对修饰行为的关注提供了生物学解释。     

亲环境行为研究中情感的类别、维度及其作用机理

从近20年来境外学者对亲环境行为的研究文献看, 情感的作用越来越受到关注。一个大致结论是, 情感对亲环境行为的影响往往大于认知, 有更重要的驱动作用。首次对境外学者的情感与亲环境行为研究进行了梳理和回顾。在亲环境行为研究中, 情感的类别和维度有4种划分标准, 即呈现形态、体验结构、时间维度和责任归属; 情感对亲环境行为的作用机理可以通过情感因素在亲环境行为模型中的三种角色加以分析; 情感在规范激活模型和计划行为理论模型的拓展中扮演了重要角色, 有效提升了拓展模型的解释力。未来研究需要更重视情感在亲环境行为中的测量范式、研究深度和动态影响机制。     

人际冲突中失望的个人效应及冲突类型的调节作用

通过两个计算机情景模拟实验, 分别采用“保证游戏”与“最后通牒博弈”范式, 考察了人际冲突中失望的个体对于威胁评价与冲突行为的影响。在此基础上进一步探讨了冲突类型对人际冲突中失望个人效应的调节作用。结果发现：(1)失望个体相比无情绪个体的威胁评价更高, 冲突行为更多。(2)冲突类型影响处于失望状态的个体的威胁评价, 即价值观冲突中失望个体的威胁评价要高于利益冲突中失望个体的威胁评价; 但是冲突类型并不影响失望个体的冲突行为。     

Experimental study of the differential effects of playing versus watching violent video games on children's aggressive behavior

There is great concern about the effects of playing violent video games on aggressive behavior. The present experimental study was aimed at investigating the differential effects of actively playing vs. passively watching the same violent video game on subsequent aggressive behavior. Fifty-seven children aged 10-13 either played a violent video game (active violent condition), watched the same violent video game (passive violent condition), or played a non-violent video game (active non-violent condition). Aggression was measured through peer nominations of real-life aggressive incidents during a free play session at school. After the active participation of actually playing the violent video game, boys behaved more aggressively than did the boys in the passive game condition. For girls, game condition was not related to aggression. These findings indicate that, specifically for boys, playing a violent video game should lead to more aggression than watching television violence.     

Parents' description of conduct problems in their children - a test of the Eyberg Child Behavior Inventory (ECBI) in a Swedish sample aged 3-10

The Eyberg Child Behavior Inventory (ECBI) is a widely used 36-item uni-dimensional parent rating scale constructed to measure disruptive behavior problems in children. However, in an American sample a 22-item version, including three subscales, has been suggested in order to increase the usefulness of the ECBI. Two studies were conducted to test the ECBI in a Swedish sample (N = 841). The aims of Study I were (a) examine the psychometric properties of the ECBI (b) to investigate the correspondence between mothers' and fathers' ratings, and (c) to obtain Swedish norms. The aim of Study II was to test the suggested three-factor solution in the Swedish sample using a confirmatory factor analysis (CFA). The ECBI showed good psychometric properties also in the present study, and Swedish normative data is presented. The best-fitting CFA-model was identical to the previously suggested three-factor model, which thus might be a useful alternative to the 36-item version.     

The Effect of Residential Neighborhood on Child Behavior Problems in First Grade

Child behavior problems have been identified as being responsible for the greatest reduction in quality of life for children between ages 1 and 19. In this study, we examine whether neighborhood social processes are associated with differences in child behavior problems in an economically and racially diverse sample of 405 urban-dwelling first grade children and whether parenting behavior mediates and/or moderates the effects of neighborhoods. Furthermore, we examine whether neighborhood social processes play the same role with regards to child behavior problems at differing levels of neighborhood economic impoverishment. Results of multivariate multilevel regression analyses indicate that a high negative social climate is associated with greater internalizing problems. High potential for community involvement for children in the neighborhood was associated with fewer behavior problems, but only in economically impoverished neighborhoods. Differences in parenting behavior did not appear to mediate neighborhood effects on behavior problems, and parenting characterized by a high degree of positive involvement was associated with fewer behavior problems in all types of neighborhoods.     

Maternal Predictors of Rejecting Parenting and Early Adolescent Antisocial Behavior

The present study examined relations among maternal psychological resources, rejecting parenting, and early adolescent antisocial behavior in a sample of 231 low-income mothers and their sons with longitudinal assessments from age 18 months to 12 years. The maternal resources examined were age at first birth, aggressive personality, and empathy. Each of the maternal resources predicted rejecting parenting during early childhood in structural equation models that controlled for toddler difficult temperament, and rejecting parenting in early childhood predicted antisocial behavior in early adolescence. Rejecting parenting accounted for the indirect effect of each of the maternal resources on antisocial behavior, but a direct effect was also supported between maternal aggressive personality and youth antisocial behavior. Results highlight the importance of these relatively understudied maternal resources and have implications for prevention and intervention programs that focus on parenting during early childhood.     

Relationships Between Parental Negativity and Childhood Antisocial Behavior over Time: A Bidirectional Effects Model in a Longitudinal Genetically Informative Design

This study examined the direction and etiology underlying the relationships between parental negativity and early childhood antisocial behavior using a bidirectional effects model in a longitudinal genetically informative design. We analyzed parent reports of parental negativity and early childhood antisocial behavior in 6,230 pairs of twins at 4 and 7 years of age. Results from a cross-lagged twin model contribute to the understanding of the mechanisms underlying the bidirectional processes involved in parental negativity and childhood antisocial behavior. Specifically, the findings of this study suggest that the association between parenting and child antisocial behavior is best explained by both parent-driven and child-driven effects. We found support for the notion that parent's negative feelings towards their children environmentally mediate the risk for child antisocial behavior. We also found evidence of genetically mediated child effects; in which genetically influenced antisocial behavior evoke parental negativity towards the child.     

Executive Functions in Preschool Children with Aggressive Behavior: Impairments in Inhibitory Control

The question whether executive function (EF) deficits in children are associated with conduct problems remains controversial. Although the origins of aggressive behavior are to be found in early childhood, findings from EF studies in preschool children with aggressive behavior are inconsistent. The current study aimed to investigate whether preschool children with aggressive behavior show impairments in EF. From a population-based sample, 82 preschool children who were showing aggressive behavior as indicated by scores at or above the 93rd percentile on the Aggressive Behavior Scale of the CBCL 1 1/2-5 were selected. These children with aggressive behavior were matched on IQ to a group of typically developing control children (N = 99). Six neuropsychological tasks were administered to assess set shifting, inhibition, working memory and verbal fluency. A factor analysis was conducted which yielded one clear factor: inhibition. Aggressive preschool children showed poorer performance on this inhibition factor than control children and boys performed worse on this factor than girls. This association between aggressive behavior and inhibition deficits was maintained after controlling for attention problems. In addition, gender differences in all EFs measured were found with boys exhibiting more impairment in EF than girls. These findings demonstrate that preschool children with aggressive behavior show impairments in inhibition, irrespective of attention problems.
