外倾性和正性情绪关系的研究述评

人格特质与情绪关系的研究表明外倾性与正性情绪存在一定相关，主要表现为以下几方面：（1）外倾个体在日常生活中体验到更多的正性情绪；（2）外倾个体对正性刺激有更为强烈的愉悦体验和情绪反应；（3）外倾个体对正性刺激有注意等认知加工偏向；（4）外倾程度与皮层及皮层下某些组织的激活程度相关。随着认知神经科学的发展，ERP及fMRI技术逐步被引入到这方面的研究中，进而从脑机制等方面更加客观的揭示了外倾性与正性情绪的关系。通过整合近年来的研究成果，分析现阶段的研究疑点，从人格理论假设，人格测量方法和实验方法这个三个方面探悉了疑点存在的原因，并在此基础上展望未来发展趋势

The Relationship Between Extroversion and Positive Affects

Considerable research confirmed that extroversion plays an important part in the processing of positive emotions. In general, the relationship between extraversion and positive emotion includes: (1) extroverts experience more positive affects than less extroverted individuals in life settings; (2) extroverts react more strongly to positive stimuli; (3)it is possible that there is an attentional bias of extroverts for emotionally positive stimuli; (4)Amygdala and other structure activation for happy expressions correlate positively and significantly with the degree of extraversion. Along with the development of cognitive neuroscience, which aims to delineate mechanisms underlying brain-behavior interrelations, we can explore the relationship between extroversion and positive affects more accurately. This paper integrated numerous experimental results, analyzed the reasons for the conflicts, and proposed new directions of the future research in the relation between extroversion and positive affects.
