Do peer relationships mediate the association between children’s facial emotion recognition ability and their academic attainment? Findings from the ALSPAC study

We examined whether children’s facial emotion recognition ability predicted their academic attainment over time, and whether peer relationships mediated that association. A secondary aim was to test whether the putative causal pathways would be significantly different for boys and girls. The model was tested using data from The Avon Longitudinal Study of Parents and Children (ALSPAC), a prospective longitudinal cohort population. Facial emotion recognition ability was assessed using the Diagnostic Assessment of Non-Verbal Accuracy (DANVA) at age 8.5 years while academic attainment was measured using data on UK Key Stage 4 (General Certificate of Secondary Education) at 16 years (outcome). The teacher’s version of the Strengths and Difficulties Questionnaire was used to measure children’s peer relationship problems at 10–11 years (mediator). We adjusted for area-level socio-economic status and child’s early academic attainment, and examined whether mediation was moderated by sex. The results showed that low facial emotion recognition ability in childhood was associated with low academic attainment at age 16 years. There was evidence of mediation via peer problems, with an estimated 19% of the total effect mediated by errors in emotion recognition. Further analyses showed that there was no difference in mediation for boys versus girls. The findings suggest that children’s facial emotion recognition ability and peer relationships should be potential targets for programmes that aim to improve children’s educational attainment and their social and emotional competence.

一种关于“个人发展”的隐性知识结构

一个人成功与否，与机遇、智力、知识、性格、价值观、人生观等许多因素都相关。然而，有哪些自身的因素与个人成功直接相关呢?研究表明，IQ只是影响个人发展的一个方面。那么，如何更为全面地描述影响个人发展的因素呢?该从个人知识与“经验”的视野分析认为：隐性知识是描述影响个人发展的因素的重要途径。然后，结合斯腾伯格的成功智力理论与波兰尼的隐性知识理论，作提出了一种关于个人发展的隐性知识结构框架。

Gifted Adolescents' Perceptions of Their Roles in Nation-Building

Young people in Singapore have been urged to take an active interest in politics and nation-building. A survey was carried out on a sample of gifted adolescents to find out their perceptions of the expectations from self, parents, classmates, school and society in nation-building.

They showed reluctance in taking on a political career but showed interest in social issues, national and international affairs.

Preparing Minority Adolescents to Blend Work and Family Roles: Increasing Work-Family Conflict Management Self Efficacy

Ethnic identity, information about the world of work, and mastery in specific career skills crucially impact the process of career development among minority adolescents. Identity and conflict management skills also affect one of the major stressors experienced by employees today: the work-family conflict. This paper presents a culturally appropriate career intervention program for increasing Israeli Arab adolescents’ self-efficacy to manage work and family roles, and feedback from 15 participants in a preliminary pilot intervention. The program comprised three units: identity exploration, information, and skill transfer. The intervention was grounded in the career development literature on minorities, on work-family conflict research, and on social cognitive career theory. The proposed strategy also included process variables comprising critical career intervention components. The program is seen as having potential for being implemented in other cultural contexts.
