目的：本研究采用纵向研究的方法，比较了典型语言发育（TD）儿童和语言发育迟缓（LD）儿童的手和食指指向动作的发展。首先，我们研究了在生命的第二年，指向手势的数量和形式是否是后期LD的潜在指标。方法：对30名TD儿童和10名LD儿童及其主要照顾者在自然环境中进行了5次为期12~21个月的观察。语言技能进行了评估，在24 months.Results：与TD的儿童相比，LD的儿童使用较少的食指点在12和14个月，但更多的指向手势，在21个月。有或没有LD的儿童照顾者之间的口头或手势输入没有显着差异。结论：使用更多的食指点在第二年的生活开始与TD，而使用更多的指向手势在第二年的生活结束与延迟收购。无论是口头或手势输入的照顾者占儿童的技能的差异。
Purpose: This longitudinal study compared the development of hand and index-finger pointing in children with typical language development (TD) and children with language delay (LD). First, we examined whether the number and the form of pointing gestures during the second year of life are potential indicators of later LD. Second, we analyzed the influence of caregivers' gestural and verbal input on children's communicative development.Method: Thirty children with TD and 10 children with LD were observed together with their primary caregivers in a seminatural setting in 5 sessions between the ages of 12 and 21 months. Language skills were assessed at 24 months.Results: Compared with children with TD, children with LD used fewer index-finger points at 12 and 14 months but more pointing gestures in total at 21 months. There were no significant differences in verbal or gestural input between caregivers of children with or without LD.Conclusions: Using more index-finger points at the beginning of the second year of life is associated with TD, whereas using more pointing gestures at the end of the second year of life is associated with delayed acquisition. Neither the verbal nor gestural input of caregivers accounted for differences in children's skills.
