本研究考察了在三个纵向观察点上婴儿有节奏的手臂抖动和偏侧性的变化：重复牙牙学语开始前、开始时和开始后。研究人员对4 - 9个月大的婴儿在家中玩两个视觉上相同的可听和无声摇铃的过程进行了录像，每个摇铃在中线呈现1.5分钟。从学牙前到开始学牙阶段摇铃的频率急剧增加；但没有迹象表明这种增加只发生在右臂上。这一发现表明，咿呀学语的开始和有节奏的手臂活动的增加之间的联系可能不是语言特定机制的产物，而是一个更广泛的发展过程的一部分，这个过程也是感知和运动的。(C) 2006爱思唯尔公司版权所有。
This study examined changes in rhythmic arm shaking and laterality biases in infants observed longitudinally at three points: just prior to, at, and just following reduplicated babble onset. Infants (ranging in age from 4 to 9 months at babble onset) were videotaped at home as they played with two visually identical audible and silent rattles presented at midline for 1.5 min each. Rate of rattle shaking increased sharply from the pre-babble to the babble onset session; but there was no indication that this increase was specific to the right arm. This finding suggests that the link between babble onset and increased rhythmic arm activity may not be the product of language-specific mechanisms, but is rather part of a broader developmental process that is also perceptual and motor.
