中文摘要： 焦虑是在人类日常生活中常见的一种负性情绪。探讨焦虑情绪对个人生活和工作能力的影响，是生理学界的一项重要课题。过往研究显示焦虑会对社交能力和技巧带来显著的负面影响。在社会决策领域中，这种影响的具体表现是高焦虑者比低焦虑者更倾向于采取回避策略。然而，这方面的探讨正处于起步阶段，研究领域尚存在不少空白。本项目的主题是结合基于脑电的事件相关技术，研究焦虑对社会决策行为的影响机制。研究的问题包括：在个体层面上，高焦虑者是否会更容易受到外界信息的影响，表现出更强的从众行为和权威依从倾向；与他人进行社会比较或社会竞争的动机是否会被削弱；在群体层面上，高焦虑者是否更容易表现出人际信任，以及是否会表现出更强的服从集体倾向。预计本项目将会推动对焦虑情绪与认知活动之间关系的认识，并对焦虑障碍的临床评估起到一定参考作用。

英文摘要： Anxiety is one of the most important kinds of negative emotions in our daily life. The potential influence of anxiety on personal life and cognitive ability is an important topic in the area of physiology. Previous studies reveal that anxiety significantly dampens social skills, for instance, high-anxious people are more likely than low-anxious people to choose avoidance strategy during social decision-making. Nevertheless, the research on this behavioral pattern has only developed for a few years and many questions remain unsolved. The current project aims to investigate the underlying mechanisms of the impact of anxiety on social decision-making. The following issues are addressed: on individual level, whether high-anxious people are more likely to be affected by social information, and show the willingness to be conformity and obey authority; whether the motive to be involved in social comparison and social competition would be weakened among high-anxious people; on group level, whether anxious people are more likely to show interpersonal trust and collectivism. The answers to these questions would prove beneficial to the cognitive and clinical studies on anxiety.
