小学儿童欺负行为与个性特点和心理问题倾向的关系

本研究采用问卷的方式测量了儿童欺负行为与个性及心理问题倾向之间的关系。结果表明：欺负组被试在个性特征上以高精神质和相对外倾型为典型特征;受害组被试以高神经质和内倾型为典型特征。在心理问题倾向上欺负组被试更多地表现出冲动倾向、学习问题和师生关系紧张等问题倾向;受害组被试更多地表现出孤独倾向、缺乏自信、学习问题和同伴关系紧张等问题。     

Explaining Social Disparities in Mathematical Achievement: The Role of Motivation

This study examined the role of motivation as a mediator of the relationship between parents' socio‐economic status (SES) and children's standardized test achievement in math. We employed a one‐year longitudinal approach using Programme for International Student Assessment (PISA) 2003 and a follow‐up exam in 2004. The sample consisted of N = 6020 German students (mean age 15.5 years, SD = .55) who continued school after Grade 9 (PISA 2003) and were in Grade 10 at the time of PISA 2004. Children completed measures related to their parents' SES, math‐specific self‐concept, task‐specific and global self‐efficacy, and interest, intelligence and mathematical competence. We found a small to moderate correlation between parents' SES and children's achievement. All motivational constructs partially mediated the relationship between father's SES as well as a family index for SES (economic, social, and cultural status) and children's mathematical competence, but only math‐specific self‐concept and self‐efficacy were significant mediators for mother's SES. Even when simultaneously considering the mediating effect of children's intelligence and prior achievement, the mediation effects of motivation remained significant. These results are important for our understanding of educational equality. Copyright © 2016 European Association of Personality Psychology

社交网站中的自我表露与青少年生活满意度：一个有调节的中介模型

采用问卷调查法,以1556名中学生为研究对象,考察社交网站中的自我表露对青少年生活满意度的影响及其作用机制。结果显示：（1）社交网站中的自我表露与青少年生活满意度呈正相关;（2）友谊质量在社交网站中的自我表露对青少年生活满意度的影响中起部分中介作用;（3）扩展性社交倾向在社交网站中的自我表露通过友谊质量影响青少年生活满意度的作用中起调节作用。具体而言,上述中介作用仅存在于扩展性社交倾向较高的个体中。

Behavioral variability in an evolutionary theory of behavior dynamics

McDowell’s evolutionary theory of behavior dynamics (McDowell, 2004) instantiates populations of behaviors (abstractly represented by integers) that evolve under the selection pressure of the environment in the form of positive reinforcement. Each generation gives rise to the next via low‐level Darwinian processes of selection, recombination, and mutation. The emergent patterns can be analyzed and compared to those produced by biological organisms. The purpose of this project was to explore the effects of high mutation rates on behavioral variability in environments that arranged different reinforcer rates and magnitudes. Behavioral variability increased with the rate of mutation. High reinforcer rates and magnitudes reduced these effects; low reinforcer rates and magnitudes augmented them. These results are in agreement with live‐organism research on behavioral variability. Various combinations of mutation rates, reinforcer rates, and reinforcer magnitudes produced similar high‐level outcomes (equifinality). These findings suggest that the independent variables that describe an experimental condition interact; that is, they do not influence behavior independently. These conclusions have implications for the interpretation of high levels of variability, mathematical undermatching, and the matching theory. The last part of the discussion centers on a potential biological counterpart for the rate of mutation, namely spontaneous fluctuations in the brain's default mode network.     

Both non-symbolic and symbolic quantity processing are important for arithmetical computation but not for mathematical reasoning

This study investigated whether numerical processing was important for two types of mathematical competence: arithmetical computation and mathematical reasoning. Thousand eight hundred and fifty-seven Chinese primary school children in third through sixth grades took eight computerised tasks: numerical processing (numerosity comparison, digit comparison), arithmetical computation, number series completion, non-verbal matrix reasoning, mental rotation, choice reaction time, and word rhyming. Hierarchical regressions showed that both non-symbolic numerical processing (numerosity comparison) and symbolic numerical processing (digit comparison) were independent predictors of arithmetical computation but neither was a predictor of mathematical reasoning (assessed by number series completion). These findings suggest that the cognitive basis of mathematical performance varies depending on the type of mathematical competence measured.     

Social exclusion affects aggressive driving behaviour: The mediating effect of prosocial tendencies and driving anger

Social exclusion—being rejected or ignored by individuals or groups—is a common and adverse experience in social life. As a social activity, driving behaviour can be influenced by many factors. Whether social exclusion is one of these factors is an open question. Therefore, the aim of this study is to explore the impact of the social exclusion experience on individuals and their driving behaviours and the mediating effect of prosocial tendencies and driving anger. A total of 240 (104 males and 136 females) participants from China completed a questionnaire including the Ostracism Experiences Scale (OES), the prosocial tendencies measure (PTM), the Driving Anger Scale (DAS) and the Driver Behaviour Questionnaire (DBQ). The hierarchical multiple regression analysis and pathway analysis results showed that social exclusion experience and driving anger positively predicted aberrant driving behaviours (including aggressive violations, ordinary violations, lapses and errors), while prosocial tendencies had a negative impact on aberrant driving behaviour. Moreover, prosocial tendencies and driving anger mediated the relationship between social exclusion and driver behaviour, accounting for 11.18% and 46.71% of the total effect, respectively. The chain-mediated effect of prosocial tendencies and driving anger was also significant, accounting for 5.26% of the total effect of social exclusion on driver behaviour. This study examines the mechanisms underlying social exclusion experiences that positively predict individuals' unsafe driving behaviours, thereby filling a gap in social exclusion research and suggesting new avenues of exploration into the personal and social influences that affect driving behaviours.
