1、Talk 2The Nature of Emotions-II2008-ISeminar of emotions12008-ISeminar of emotions2生物社会研究观点(bio-social approach)特点：注重情绪的生理/表情行为反应成分，生理过程是情绪过程中必须的和充分的过程；注重遗传和生物基础对情绪各方面特点的作用；社会/认知/学习/自我/角色/文化等因素的作用是与生物因素相互作用地影响情绪过程；主要研究：具体情绪（discrete emotion)；情绪的生物基础；情绪与高级认知的相互作用；情绪与人格特质的关系；情绪发展与人格发展；情绪发展与心理病理发展；2008
2、-ISeminar of emotions3认知建构研究(Cognitive/Social/Constructive approach)认知建构理论的特点：强调认知建构对情绪的作用，甚至将认知作为情绪的一个成分；认知评价是必须和充分的条件;不太注重情绪的遗传/生物基础；生理反应是伴随的状态，对生理反应的知觉可以增强情绪；比较现象学研究取向；主要领域（课题）：cognitive effects on emotions.Theories of Cognitive Appraisal;Self and Emotions;Attribution and emotion;Memory and emoti
