这项研究旨在提供婴儿声音-运动协调的总体情况，并测试Iverson和Thelen（1999）的手势-语言系统发展模型所产生的预测。47名6至9个月大的婴儿与主要照顾者一起玩摇铃和玩具。结果表明，与年龄相关的声音-运动协调频率增加，与腿部或躯干运动相比，手臂（特别是右臂）的协调性更强，并且时间模式类似于成人手势-语言联合生产。有节奏的发声（辅音和元音的重复）在有节奏的运动时比没有节奏的运动时更容易发生，有节奏的体力活动比没有体力活动时更容易发生，而且咿呀学语者的声音和体力协调率高于学龄前儿童。
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 co-productions. 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.
