A total of 94 adolescents (M age = 14.2 years) participated in 20-minute hypothetical conflict discussions with either their mothers or fathers (24 daughter-mother, 22 son-mother, 25 daughter-father, 23 son-father dyads). Audiotaped conversations were coded for speakers’ conversational style (overlaps between turns, simultaneous speech, and successful interruptions) and hostile emotional expressions (i.e., disgust/contempt). Adolescents used a conversational style that included more overlaps, simultaneous speech and successful interruptions than their parents, with the greatest differences in styles found for adolescents and their mothers. Adolescents’ and parents’ conversational styles and expressions of disgust were analyzed in modeling procedures in an attempt to predict selfreported perceptions of adolescent-parent conflict. Results revealed that adolescents’ rates of disgust were positively predicted from both the degree of difference in the adolescent’s and parent’s conversational styles and from the parent’s rates of disgust expressions. In turn, adolescents’ expressions of disgust were found to positively predict adolescents’ perceptions of levels of relationship conflict with their parents.
