This study was designed to provide a general picture of infant vocal-motor coordination and test predictions generated by Iverson and Thelen's (1999) model of the development of the gesture-speech system. Forty-seven 6- to 9-month-old infants were videotaped with a primary caregiver during rattle and toy play. Results indicated an age-related increase in frequency of vocal-motor coordination, greater coordination with arm (specifically right arm) than leg or torso movements, and a temporal pattern similar to that in adult gesture-speech coproductions. Rhythmic vocalizations (consonant-vowel repetitions) were more likely to occur with than without rhythmic movement, and with rhythmic manual than with nonmanual activity, and the rate of vocal-manual coordination was higher in babblers than in prebabblers.
本研究旨在描绘婴儿发声-运动协调的总体情况，并检验艾弗森和特伦（1999年）手势-言语系统发展模型所产生的预测。47名6至9个月大的婴儿在玩拨浪鼓和玩具时与主要照料者一起被录像。结果表明，发声-运动协调频率随年龄增长而增加，与手臂（特别是右臂）的协调比与腿部或躯干运动的协调更好，并且时间模式与成人手势-言语协同产生的模式相似。有节奏的发声（辅音-元音重复）在有节奏运动时比无节奏运动时更有可能出现，在有节奏的手动活动时比非手动活动时更有可能出现，并且牙牙学语者的发声-手动协调率高于前牙牙学语者。
