摘要共有48名男婴在0;3岁和0;4岁时经历了母亲的会话话轮转换或随机反应。在这两个时期，婴儿的发声率并没有显着影响母亲的反应的偶然性，但偶然性改变了婴儿的发声模式的时间参数。当母亲以随机模式与婴儿交谈时，婴儿往往会产生更多的爆发或分组发声。当婴儿0;3岁时，这种爆发最常发生在0.5 - 1.5秒的间隔，而当婴儿0;4岁时，这种爆发最常发生在明显更长的间隔，1.0 - 2.0秒。这种差异对应于母亲在0;3和0;4时对婴儿的发声作出偶然反应的间隔之间的差异。当婴儿0; 3岁时，婴儿发声开始与母亲发声开始之间的间隔很少超过0.5秒，而当婴儿0; 4岁时，婴儿发声开始与母亲发声开始之间的间隔大多分布在0.5和1.0秒之间。在自发发声后，婴儿倾向于停顿，好像在听母亲可能的声音反应。在没有回应的情况下，他重复地发声。婴儿根据他最近与母亲轮流的经验灵活地改变了两次连续发声之间的间隔。
ABSTRACT A total of 48 male infants experienced either conversational turn-taking or random responsiveness of their mothers when aged 0;3 and 0;4. In both periods, the infant's rate of vocalizing was not significantly influenced by the contingency of the mother's response, but contingency altered the temporal parameters of the infant's vocal pattern. Infants tended to produce more bursts or packets of vocalizations when the mother talked to the infant in a random pattern. When the infants were aged 0;3 such bursts occurred most often at intervals of 0·5–1·5 sec whereas when they were aged 0;4 they took place most frequently at significantly longer intervals, of 1·0–2·0. The difference corresponded to the difference between intervals with which the mother responded contingently to vocalizations of the infant at 0;3 and at 0;4. While the intervals (between the onset of the infant's vocalization and the onset of the mother's vocalization) rarely exceeded 0·5 sec when the infant was aged 0;3, they were mostly distributed between 0·5 and 1·0 sec when he was aged 0;4. After vocalizing spontaneously, the infant tended to pause as if to listen for a possible vocal response from the mother. In the absence of a response, he vocalized repeatedly. The intervals between the two consecutive vocalizations were changed flexibly by the infant according to his recent experience of turn-taking with the mother.
