Adult-like temporal characteristics of mother-infant vocal interactions.


29 mothers and their 9-month-old-infants participated in a semistructured play episode. The temporal patterning of their vocal behavior was analyzed by means of a computerized analogue-to-digital conversion system (AVTA). Time-series regression analysis was employed to determine interpersonal influence over the course of the exchange for a variety of temporal parameters. The analysis revealed that the dyads engaged in alternating vocalization to a greater degree than simultaneous vocalization, and that there is a pattern of mutual influence (interpersonal accommodation) for switching pauses. The results suggest that some of the formal attributes observed in conversational exchanges between adult speakers are observable prior to the emergence of linguistic competence.
