音乐愉悦体验的神经机制

愉悦情绪体验是音乐活动中最普遍的心理现象。通过系统回顾相关的神经科学研究, 认为音乐愉悦体验与大脑奖赏系统的活动有关, 并涉及伏隔核与听觉皮层等其他脑区的交互。在这个过程中, 多巴胺的传递与音乐愉悦体验存在因果联系。基于预期视角, 奖赏预测误差理论和音乐信息理论模型可以解释音乐愉悦体验的产生机制。未来研究应进一步检验伏隔核及各皮层在音乐愉悦体验中的功能, 并整合不同的预期理论。     

动作视频游戏对发展性阅读障碍者阅读技能的影响及其内在机制

发展性阅读障碍是一种在获得阅读技能方面的特殊困难, 这种障碍会严重影响个体的发展, 如何帮助发展性阅读障碍者改善其阅读技能是近年来研究的焦点。传统的干预方法主要针对发展性阅读障碍者的语音缺陷, 这类方法存在一些问题, 如费时费力、给阅读障碍者带来阅读压力等。近年来, 大部分研究表明通过趣味性的动作视频游戏训练可以显著地提高发展性阅读障碍者的阅读技能, 但是其背后的机制尚不明确。基于大细胞通路缺陷理论框架, 从视觉空间注意、注意跨通道转换、视觉运动加工等方面来梳理动作视频游戏与阅读之间的关系, 揭示了动作视频游戏训练对阅读效率影响的可能内在机制。未来的研究可以在大细胞通路缺陷理论的框架下, 深入分析动作视频游戏改善阅读的神经机制, 并尝试开发更适合发展性阅读障碍者的干预程序。     

受害者视角下职场不文明行为对组织公民行为影响的双路径机制

本文基于资源保存理论,探讨职场不文明行为对组织公民行为的影响机制及作用边界。通过问卷调查315份员工和领导的配对样本数据,结果表明：职场不文明行为负向预测组织公民行为,情绪耗竭、组织自尊中介了职场不文明行为与组织公民行为间的关系;心理韧性调节了情绪耗竭、组织自尊在二者间的中介作用。     

情感计算技术如何推动犯罪风险评估工具的发展？

摘 要 随着近年来人工智能深度学习技术的发展,情感计算与人格计算技术日渐成熟,在许多实际应用场景中取得了良好的表现,当前人工智能情感计算技术应用于犯罪风险评估领域,能够有效解决目前主流的风险评估工具难以解决的个体内差异性的预测因子评估问题以及被测评参与者因社会赞许性而导致结果失真的问题。本文在详细阐述目前主流评估工具的局限性基础上,详细阐述了以情感计算技术为支撑的动态风险评估工具的设计思路、目前已有的技术方案以及设计细节的理论依据,在此基础上最后提出以人工智能技术为支撑的新型评估工具的未来发展方向。     

On the evaluation of one-sided evidence

We examine predictions and judgments of confidence based on one-sided evidence. Some subjects saw arguments for only one side of a legal dispute while other subjects (called ‘jurors’) saw arguments for both sides. Subjects predicted the number of jurors who favored the plaintiff in each case. Subjects who saw only one side made predictions that were biased in favor of that side. Furthermore, they were more confident but generally less accurate than subjects who saw both sides. The results indicate that people do not compensate sufficiently for missing information even when it is painfully obvious that the information available to them is incomplete. A simple manipulation that required subjects to evaluate the relative strength of the opponent's side greatly reduced the tendency to underweigh missing evidence.     

Explanations and Evaluations by Turks and Dutchmen of Norm Violating Ingroup and Outgroup Behaviour

Group-serving biases in the explanation and evaluation of norm violating ingroup and outgroup behaviour are investigated. The intergroup relationship concerns autochthonous Dutchmen and allochthonous Turks living in The Netherlands. It was hypothesized that Dutch observers exhibit group-serving biases. No hypothesis was formulated for the Turks. A 2×2 design was employed with actor's group membership (ingroup or outgroup), and observer's group membership (Dutch or Turkish) as factors. 50 Dutch and 50 Turkish pupils responded to a hypothetical norm violating situation. The Dutch displayed a group-serving bias on some variables, but ingroup derogation on others. The Turks engaged in a consistent group-serving bias. These outcomes are discussed in terms of the groups need to strive for a positive social identity vis-a)-vis one another and the role explaining away negative ingroup behaviour in fulfilling this need.
