Using a sample of college students assembled in groups of dyads representing all possible combinations of gender and race, this study sought to determine whether attributions made by conversational participants about each other are a function of the time patterns of their verbal interaction. It was found that the participants' pause and switching pause probabilities, and their speech rates, significantly influenced the extent to which they were perceived by their partners in terms of negative and/or positive attributes. It is concluded that the relationship between the temporal patterns of dyadic verbal exchange and the interpersonal perceptions of the participants in the exchange are affected by characteristics both of the participants and of the situation in which they interact.
