Recent research into whether males and females differ in their communication has been confounded by several variables: perceptual measures, observing isolated behaviors, and same-sex or mixed-sex composition of the communicative system. Some research has suggested that the interactional context may affect whether males and females communicate differently at all. This study sought to determine the differential impact of sexual composition and one aspect of interactional context (specifically, competitive or cooperative orientation) on interaction patterns in same-sex and mixed-sex dyads. Results confirm the expectation that competitive/cooperative orientation exerts a significant impact on both content and relationship patterns of interaction. Results also demonstate that the sexual composition of the dyads did not affect the interaction patterns, measured on any of five dimensions of interactional functions, in competitive dyads, cooperative dyads, or all dyads taken together.
