The concurrent and predictive relations of sensorimotor behavior and play to language in the second year were assessed. 19 preterm and 20 full-term infants were tested at 13 1/2 and 22 months of age. Functional play directed toward dolls and other persons and meaningfully related sequences of functional and symbolic acts at 13 1/2 months were associated with language measured at 13 1/2 months and 9 months later. Concurrent positive relations between sensorimotor behavior and language were found only at 22 months for object-permanence skills. There were no significant positive relations between sensorimotor behaviors at 13 1/2 months and language at 22 months. The consistent relations found between play and language in this research derived from the infants' ability to translate experience into symbols that are used as a means of interacting and communicating with others. Sensorimotor behavior and language were much more loosely associated in the same age period.
对第二年中感觉运动行为和玩耍与语言之间的并发关系和预测关系进行了评估。19名早产儿和20名足月儿在13.5个月和22个月大时接受了测试。13.5个月时针对玩偶和其他人的功能性玩耍以及功能性和象征性动作的有意义相关序列，与13.5个月及9个月后测得的语言能力相关。仅在22个月时，发现客体永久性技能的感觉运动行为与语言之间存在并发的正向关系。13.5个月时的感觉运动行为与22个月时的语言之间没有显著的正向关系。本研究中发现的玩耍与语言之间的一致关系源于婴儿将经验转化为符号的能力，这些符号被用作与他人互动和交流的手段。在同一年龄段，感觉运动行为和语言的关联要松散得多。
