本研究以16名早产儿和两组12、18和24个月的足月儿为研究对象，对他们的交际手势发展进行了纵向研究。在母子观察期间，分析了儿童的自发交际手势。早产儿的运动，心理和语言发育也进行了测量。除了在18个月和24个月时使用手势加单词组合外，两组之间的手势交流发展没有显着差异，此时足月儿比早产儿产生更多的组合。对于早产儿，生产的指向12个月与词汇技能在24个月，是使用手势加字的话语在18个月与形态句法技能在24个月。我们的分析还揭示了一个亚组的早产儿的特点是低出生体重和心理评分谁表现出持久的增加，随着时间的推移，在沟通的手势生产。这种情况可能与语言习得的后期延迟有关。(C)2012 Elsevier Inc.

This longitudinal study examined the development of communicative gesture in 16 preterm children and two groups of full term children at 12, 18 and 24 months of age. Children's spontaneous communicative gestures were analyzed during mother-child observation sessions. Preterm children's motor, mental and linguistic development were also measured. The development of gestural communication did not significantly differ between the groups except for the use of gesture-plus-word combinations at 18 and 24 months, when full term children produced significantly more combinations than preterm children. For preterm children, the production of pointing at 12 months was positively associated with lexical skills at 24 months as was the use of gestures-plus-word utterances at 18 months with morphosyntactic skills at 24 months. Our analyses also revealed a subgroup of preterm children characterized by a low birth-weight and mental scores who demonstrated an enduring increase in communicative gesture production over time. This profile could be associated with later delays in language acquisition. (C) 2012 Elsevier Inc. All rights reserved.
