主动性攻击和反应性攻击的遗传基础研究述评

根据攻击行为的意图可以将攻击分为主动性攻击和反应性攻击。近年来, 研究者对遗传和环境在主动性攻击和反应性攻击发展中的作用进行了探讨, 并获得了两类攻击具有不同遗传和环境基础的重要发现。既有研究主要采用定量行为遗传学研究的范式考察两类攻击的遗传基础, 未来研究应从确定与两类攻击相关的候选基因、遗传基因与环境的交互作用机制、遗传基因作用于两类攻击的神经生物机制等方面展开。     

具身框架下的社会认知研究述评

具身理论是继计算隐喻、联结主义之后诠释人类是如何获取知识表征世界这样一个本质性问题的新视角, 指出概念系统的建构对真实身体及其身体活动的体验的依赖, 即具身性。随着认知科学的快速发展, 具身理论已从原始阶段的哲学思辨成为认知心理学、社会认知等领域解释各种现象的一种新的研究范式。文章简要回顾了具身理论的起源及发展, 选取了社会认知心理学中主要的研究对象, 即态度、社会知觉、情绪等, 总结具身理论在这些领域的研究范式及最新研究成果。最后, 文章从实证的角度指出在社会认知领域中以具身理论为框架开展实证研究时值得注意的要点, 并提出此类研究结合其他研究视角(例如, 神经科学, 跨文化心理学)的可能性。     

知识产权与人权之法哲学思考

知识产权的属性是知识产权法律制度建立的基石,关于知识产权权属问题的研究,不同的学者从不同的价值角度出发得出不同的结论.知识产权究竟是私权还是人权,抑或两种属性兼备?私权与人权是非此即彼的对立冲突关系,还是内在的协调与统一关系?这一问题,不仅引发了学者们的深入研究,也引起了国际社会的探讨与关注.     

青少年冒险行为及其与人格、依恋的关系

该文采用问卷法对671名初、高中生及大学生进行青少年冒险行为、人格、同伴依恋调查。结果发现,性别、年龄、独生子女与否对青少年冒险行为均有不同程度的影响作用;人格五因素既对青少年冒险行为有直接预测作用,又以同伴依恋的疏远维度为中介间接影响青少年冒险行为。     

MAOA基因T941G多态性与同伴侵害对男青少年早期抑郁的交互作用:COMT基因Val158Met多态性的调节效应

抑郁具有复杂的多基因遗传基础,然而既有研究大多采用单基因以及单基因-环境交互设计(G×E)考察抑郁的遗传机制。以757名男青少年为被试(初次测评时Mage=11.32岁,SD=0.49岁),采用多基因-环境交互(G×G×E)设计,本研究考察了MAOA(monoamine oxidase A,单胺氧化酶A)基因T941G多态性、COMT(catechol-O-methyltransferase,儿茶酚胺氧位甲基转移酶)基因Val158Met多态性与同伴侵害对青少年早期抑郁的影响。结果显示,MAOA基因T941G多态性与同伴侵害交互作用于青少年抑郁,同伴侵害仅显著正向预测G等位基因(而非T等位基因)青少年抑郁。而且,MAOA基因T941G多态性与同伴侵害的交互作用受到COMT基因Val158Met多态性的调节,上述交互作用仅存在于COMT Met等位基因而非Val/Val基因型携带者中。研究结果显示,抑郁的产生与个体差异存在多基因与环境间的复杂交互机制。     

Measurement equivalence of the German Job Satisfaction Survey used in a multinational organization: implications of Schwartz's culture model

The authors tested measurement equivalence of the German Job Satisfaction Survey (GJSS) using structural equation modeling methodology. Employees from 18 countries and areas provided data on 5 job satisfaction facets. The effects of language and culture on measurement equivalence were examined. A cultural distance hypothesis, based on S. H. Schwartz's (1999) theory, was tested with 4 cultural groups: West Europe, English speaking, Latin America, and Far East. Findings indicated the robustness of the GJSS in terms of measurement equivalence across countries. The survey maintained high transportability across countries speaking the same language and countries sharing similar cultural backgrounds. Consistent with Schwartz's model, a cultural distance effect on scale transportability among scales used in maximally dissimilar cultures was detected. Scales used in the West Europe group showed greater equivalence to scales used in the English-speaking and Latin America groups than scales used in the Far East group.

科技侵扰与恋爱关系满意度:有调节的中介效应

采用问卷法对454名处于亲密恋爱关系中的未婚个体进行调查,考察了沟通质量在科技侵扰与亲密关系满意度之间的中介效应,及信任对这一中介过程的调节效应。结果表明：(1)科技侵扰对亲密关系满意度具有显著负向预测作用;(2)沟通质量在科技侵扰与亲密关系满意度之间起中介作用;(3)科技侵扰通过沟通质量对亲密关系满意度的中介受到信任的调节,具体来说,个体对伴侣信任水平较高时,将减弱沟通质量变差对亲密关系满意度的破坏作用。本研究在新的时代背景下探究智能手机使用在亲密互动中的影响及其中的机制和边界条件。研究结果提示,科技侵扰可以通过破坏沟通质量影响恋爱个体的亲密关系满意度,且在此过程中信任可以缓冲沟通质量变差对亲密关系的影响。     

Cognitive control and word recognition speed influence the Stroop effect in bilinguals

Bilinguals have been shown to be less susceptible to Stroop interference in their first language than monolinguals, though the cause is currently being debated. In two experiments, we explored how cognitive control and word recognition contribute to the Stroop effect by contrasting cognitive control (via a Simon arrow task), word recognition speed (via a Chinese/English word recognition task) and Stroop susceptibility (via a verbal Stroop task) between proficient and non‐proficient Chinese–English bilinguals. Compared to non‐proficient bilinguals, proficient bilinguals showed better cognitive control at inhibiting irrelevant information, and they were slower at recognising Chinese words but quicker at recognising English words. Critically, we also showed that proficient bilinguals showed a smaller Stroop effect than non‐proficient bilinguals in Chinese but a comparable Stroop effect as non‐proficient bilinguals in English. The results cannot be accounted for by cognitive control or word recognition speed alone; instead, they are best accommodated by assuming that cognitive control and word recognition speed jointly determine the Stroop effect. Thus, we conclude that enhanced cognitive control and delayed word recognition combine to reduce Stroop effect in bilinguals as compared to monolinguals.
