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.
29位母亲及其9个月大的婴儿参与了一场半结构化的游戏活动。通过计算机化的模拟-数字转换系统（AVTA）对她们的发声行为的时间模式进行了分析。采用时间序列回归分析来确定在交流过程中各种时间参数的人际影响。分析表明，二元组进行交替发声的程度高于同时发声，并且在切换停顿方面存在相互影响（人际调节）的模式。结果表明，在语言能力出现之前，就可以观察到成年说话者之间对话交流中所观察到的一些形式属性。
