The purpose of this study was to compare interaction characteristics between a group of 9-year-old Japanese stuttering children (N :3) and their mothers during free play to those of a control group of nonstuttering children (N :3) and their mothers. A 10-minute play session for each pair was analyzed in terms of a number of utterances, number of topic initiations, MLU, a number of interruptions and conversational functions. Subjects in the stuttering group showed fewer interruptions during the conversation than the subjects in the non-stuttering group. Conversational functions varied among subjects; however, 2 mothers of the stuttering group showed a tendency to control their children’s behaviors.
