This study examined the modulatory function of the positive affect in a communication context. The function of the positive affect has been examined in speci.c problem solving contexts. These studies illustrated that the positive affect made participants more .exible and creative and enhanced performance at each task. In this study, the positive affect was considered in terms of two factors—high-aroused positive and low-aroused positive—on the basis of subjective arousal level, as compared to previous studies that considered only one factor. Before a conversation task, participants ( n =66) viewed one of the films that evoked the high-aroused positive affect, low-aroused positive affect, and neutral affect. The results showed that the more the participants felt the high-aroused positive affect, the more satis.ed they were about the conversation and the less frequently did they touch themselves. However, the more the participants felt the low-aroused positive affect, the more disappointed they felt about the conversation. These results pointed out the bene.t of separation of high-aroused and low-aroused positive affects in a communication context. They were discussed in terms of dyadic relationships.
