感情の生理心理学的アプローチ(2004年度 第1回フォーラム 感情と表出研究への多彩なアプローチ)

One of the recent topics of emotional psychology is the study on functions of positive emotions. Positive and negative emotions are different in their functions and saliency. According to Fredrickson's broaden-and-build theory of positive emotions (2001), positive emotions broaden an individuals momentary thought-action repertoire toward specific actions and build the enduring personal resources, while many negative emotions narrow people's thought-action repertoire. One of the implication of this theory is that positive emotions have an undoing effect on the aftereffects of negative emotions. Folkman & Moskowitz (2000) reviewed recent studies and suggested that positive reappraisals of the situation are related to the occurrence and maintenance of positive emotion. Tezuka & Suzuki (2004) tested this undoing effect using psychological reappraisal method. Inoue (2003) also examined the undoing effects. Participants were randomly assigned and cardiovascular reactivity were induced by positive, negative and neutral images, and then participants were shown a secondary negative emotion-induced film. Findings show that the experience of positive emotions including psychological reappraisal had an undoing effect on accelerated cardiovascular reactivity and psychological arousal caused by negative emotions.
