本研究探讨了从咿呀学语阶段到单字阶段的手势和言语组合模式以及两种模态之间的时间对齐。四个加泰罗尼亚儿童在0;11，1;1，1;3，1;5，1;7的沟通行为进行了手势和声学分析。对从大约24小时的家庭录音中提取的总共4,507个交际行为的分析结果表明：（1）从早期的单字时期开始，手势开始主要与语音结合产生，而不是作为一个手势单独的行为;（2）在这些早期的手势语组合中，大多数手势都是指示手势（指向和到达手势）具有陈述性的交际目的;以及（3）在咿呀学语阶段已经存在手势和语音之间的时间协调的证据，因为手势在与它们相关联的发声之前开始，笔画起始与语音中的突出音节的起始一致，并且手势顶点在重音音节结束之前产生。这些结果表明，在过渡期之间的咿呀学语阶段和单个单词的时期，婴儿开始结合指示手势和语音，当结合起来，这两种方式是暂时协调。(C)2013爱思唯尔有限公司版权所有。
This study explores the patterns of gesture and speech combinations from the babbling period to the one-word stage and the temporal alignment between the two modalities. The communicative acts of four Catalan children at 0;11, 1;1, 1;3, 1;5, and 1;7 were gesturally and acoustically analyzed. Results from the analysis of a total of 4,507 communicative acts extracted from approximately 24 h of at-home recordings showed that (1) from the early single-word period onwards gesture starts being produced mainly in combination with speech rather than as a gesture-only act; (2) in these early gesture-speech combinations most of the gestures are deictic gestures (pointing and reaching gestures) with a declarative communicative purpose; and (3) there is evidence of temporal coordination between gesture and speech already at the babbling stage because gestures start before the vocalizations associated with them, the stroke onset coincides with the onset of the prominent syllable in speech, and the gesture apex is produced before the end of the accented syllable. These results suggest that during the transition between the babbling stage and single-word period infants start combining deictic gestures and speech and, when combined, the two modalities are temporally coordinated.
