在明暗两种环境中，给婴儿两个不同大小的发声物体，通过声音提示物体的身份。到达行为评估，以确定是否物体的大小影响准备抓取的对象。在明亮和黑暗的环境中，婴儿在接触大物体和小物体时，他们的手会对齐，这导致他们在接触大物体时伸出双手，而在接触小物体时伸出一只手。婴儿更频繁地接触底部和侧面的大物体，而不是声源所在的顶部。6.5个月大的婴儿在黑暗中伸手不仅仅是指向声源，而是显示出与物体大小有关的准备。这些发现被解释为对先前看到的物体的心理表征可以指导6.5个半月大的婴儿随后的运动行为的证据。（PsycINFO数据库记录(c) 2016 APA，版权所有）
Infants were presented with 2 sounding objects of different sizes in light and dark, in which sound cued the object's identity. Reaching behavior was assessed to determine if object size influenced preparation for grasping the object. In both light and dark, infants aligned their hands when contacting the large object compared with the small object, which resulted in a reach with both hands extended for the large object and reach with one hand more extended for the small object. Infants contacted the large object more frequently on the bottom and sides rather than the top, where the sound source was located. Reaching in the dark by 6½-mo-olds is not merely directed toward a sound source but rather shows preparation in relation to the object's size. These findings were interpreted as evidence that mental representation of previously seen objects can guide subsequent motor action by 6½-mo-old infants.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
