Abstract:
Conversational interactions of sixth-grade friends and acquaintances in mixed- and same-gender pairs were computer analyzed so that the individual and dyadic time patterns of their vocal behavior could be examined. A comparison of their time patterns revealed that the boy-boy pairs used more and longer segments of simultaneous speech with acquaintances than with friends whereas the girl-girl pairs did the opposite. In general, partners tended to coordinate the durations of their vocal behaviors with each other but, more specifically, the boys coordinated the timing of their speaking turns and switching pauses more when they were friends than when they were acquaintances, and the girls again did the opposite. Finally, the girls coordinated the durations of their pauses significantly more than did the boys regardless of whether they were with friends or acquaintances or in mixed- or same-gender pairs.
