Positive Affect, Negative Affect, and Social Interaction

Two studies explored the relations of positive and negative affect (PA and NA) to social interaction. In Study 1, unacquainted dyads were surreptitiously videotaped as they participated in a 6-min interaction. Participants then evaluated the quality of the interaction. Independent observers also rated the videotaped interactions. Trait PA was positively related to both participant and observer evaluations of interaction quality. In Study 2, undergraduates kept diaries of their social interactions for 1 week. PA was again related to interaction quality. Both PA and NA were positively related to the number of interactions in which participants engaged, and the amount of time spent engaged in social contact, although different types of social encounters produced these relations.
