Does childhood general cognitive ability at age 12 predict subjective well-being at age 52?

Drawing on a broad, multidimensional conceptualization of subjective well-being, this study examined the power of childhood general cognitive ability to predict life satisfaction, satisfaction with eight individual life domains, and the frequency of experiencing positive and negative affect in middle adulthood. Data were obtained from a representative Luxembourgish sample (N = 738; 53% female) in a longitudinal study conducted in 1968 and 2008. Childhood general cognitive ability was unrelated to life satisfaction, negatively related to negative affect and satisfaction with free time, and positively related to positive affect and satisfaction with some of the life domains associated with socioeconomic success (i.e. finances, self, housing, work, or health). This predictive power persisted even when childhood socioeconomic status was controlled.     

A key role for experimental task performance: effects of math talent, gender and performance on the neural correlates of mental rotation

The neurophysiological mechanisms underlying superior cognitive performance are a research area of high interest. The majority of studies on the brain-performance relationship assessed the effects of capability-related group factors (e.g. talent, gender) on task-related brain activations while only few studies examined the effect of the inherent experimental task performance factor. In this functional MRI study, we combined both approaches and simultaneously assessed the effects of three relatively independent factors on the neurofunctional correlates of mental rotation in same-aged adolescents: math talent (gifted/controls: 17/17), gender (male/female: 16/18) and experimental task performance (median split on accuracy; high/low: 17/17). Better experimental task performance of mathematically gifted vs. control subjects and male vs. female subjects validated the selected paradigm. Activation of the inferior parietal lobule (IPL) was identified as a common effect of mathematical giftedness, gender and experimental task performance. However, multiple linear regression analyses (stepwise) indicated experimental task performance as the only predictor of parietal activations. In conclusion, increased activation of the IPL represents a positive neural correlate of mental rotation performance, irrespective of but consistent with the obtained neurocognitive and behavioral effects of math talent and gender. As experimental performance may strongly affect task-related activations this factor needs to be considered in capability-related group comparison studies on the brain-performance relationship.     

Representations and social knowledge: An integrative effort through a normative structural perspective

The structural approach on social representations is known for the development of central core theory and its similarity with cognition-oriented sociopsychological perspectives, which has been a target of criticism. The approach has difficulty in dealing with the social dimension of knowledge and adopts a static notion of structure. Acknowledging those shortcomings, we present a revised structural conceptual model of social knowledge and social representations based on the consideration of normative and social identity processes, compatible with contributions of authors external to the classical structural approach, such as Wagner (holomorphy) and Lahlou (propagation model). After redefining the concepts of cognem and structure, we tackle thinking processes and the differences between personal and social representations, conceiving the latter as conventional codes linked to groups. Limitations of the perspective are discussed and research directions are indicated based on an understanding of structure that is broader than the one adopted by the classical approach.     

青少年高冒险行为与大脑发展

青少年时期是一个转折期,也是冒险行为多发的时期。以往有关青少年冒险行为的研究大多集中在心理学视角与社会关系学视角,双系统竞争理论从生物学视角对青少年高冒险行为作出解释。该理论认为青少年高冒险行为的产生主要是由于大脑中的社会情绪系统与认知控制系统相互竞争作用的结果。社会情绪系统对奖赏寻求起作用,而认知控制系统对执行功能起作用。较早发展的社会情绪系统与较晚才成熟的认知控制系统间的竞争是青少年冒险行为产生的原因。     

行政职业能力倾向测验:历史、现状与未来研究

经过二十多年的发展,行政职业能力倾向测验已经成为公务员考试中不可缺少的测评工具之一。在实践发展中,行测内外部的变化引发了许多研究问题。然而,现有研究的广度和深度都较为有限。为了提高行测的科学化水平,该文指出未来亟需从以下方面开展研究:(1)借鉴认知诊断理论对各个题型进行研究;(2)测量结构的确立;(3)分级分类考试的架构设计;(4)新题型开发;(5)分数合成;(6)试题公平性等。     

镜像神经元:认知具身性的神经生物学证据

传统认知心理学认为认知类似于计算机对抽象符号的加工和运算,这种观点支持了身心二元论。但是近年来兴起的具身认知运动却否定了这一观点的合理性。具身认知认为认知是身体与世界互动的结果,是身体的感觉-运动系统作用于世界而塑造出来的。认知是具身的,离不开身体的构造和感觉运动系统的作用。镜像神经元的发现支持了认知的具身特征,为认知的具身性提供了神经生物学的证据。     

压力情境认知评价与工作倦怠的关系

为探讨压力情境认知评价与工作倦怠的关系,选取北京、河南两家公司的303名员工进行了调查。分层结果分析发现,在控制了人口统计学因素之后,挑战评价对玩世不恭存在显著正向预测作用,控制评价对情绪衰竭、玩世不恭和成就感低落存在显著负向预测作用;进一步分析发现,控制评价在情绪中心应对和情绪衰竭、问题中心应对与成就感低落之间按的关系上具有调节作用。结果表明,压力情境认知评价是影响员工工作倦怠的重要因素。     

跨期选择的认知机制与神经基础

跨期选择是指个体对发生在不同时间的成本与收益进行权衡的决策过程。跨期选择的计算模型从经济学的角度用数学模型来建构时间折扣函数,而认知成分模型则从心理学的角度来研究跨期选择中的心理效应与认知成分。跨期选择的神经基础有三种不同的研究取向：双机制加工取向、单机制加工取向、自我控制取向。未来研究应该在跨期选择的认知机制、神经通路及运行机制、跨期选择的应用,以及从进化的角度对人与动物的跨期选择行为进行更深入的研究。     

Dissociating effects of subclinical anxiety and depression on cognitive control

Even at subclinical levels, anxiety and depression are associated with impaired cognitive control. It is unclear, though, to what extent these deficits reflect a common underlying dysfunction. Using a non-affective hybrid masked prime-Simon task, we obtained several measures of within- and between- trial inhibitory behavioral control in 80 young, healthy volunteers, together with measures of their anxiety and depression levels. Neither depression nor anxiety affected low-level within-trial control, or any of the between-trial control measures. However, increased levels of depression, but not of anxiety, were associated with impaired high-level within-trial control (increased Simon effect). Results indicate that depression, but not anxiety, impairs voluntary online response-control mechanisms independent of affective content.     

Using Cognitive Behavior Therapy in Clinical Work With African American Children and Adolescents: A Review of the Literature

A comprehensive review of the literature on clinical work with African American youth with cognitive behavior therapy (CBT) is presented. The strengths and limitations of CBT in relation to this population are outlined. Although CBT shows promise in helping, research on the efficacy and effectiveness of CBT in this group is lacking. Se presenta una reseña exhaustiva de la literatura sobre trabajo clínico con jóvenes Afroamericanos usando terapia cognitiva conductual (TCC). Se perfilan los puntos fuertes y las limitaciones de la TCC en relación a esta población. A pesar de que la TCC muestra signos prometedores para servir de ayuda, no hay suficiente investigación sobre la eficacia y efectividad de la TCC en este grupo.
