Children with autism spectrum disorder (ASD) or with Down syndrome (DS) show diagnosis-specific differences from typically developing (TD) children in gesture production. We asked whether these differences reflect the differences in parental gesture input. Our systematic observations of 23 children with ASD and 23 with DS (M = 2;6)-compared to 23 TD children (M = 1;6) similar in expressive vocabulary-showed that across groups children and parents produced similar types of gestures and gesture-speech combinations. However, only children-but not their parents-showed diagnosis-specific variability in how often they produced each type of gesture and gesture-speech combination. These findings suggest that, even though parents model gestures similarly, the amount with which children produce each type largely reflects diagnosis-specific abilities.
自闭症谱系障碍（ASD）或唐氏综合征（DS）儿童在手势生成方面表现出与典型发育（TD）儿童特定的差异。我们想知道这些差异是否反映了父母手势输入的差异。我们对 23 名 ASD 儿童和 23 名 DS 儿童（M=2；6）与 23 名 TD 儿童（M=1；6）进行了系统观察，他们的表达词汇相似，结果表明，在所有组中，儿童和父母都产生了类似类型的手势和手势-言语组合。然而，只有儿童——而不是他们的父母——表现出在他们产生每种类型的手势和手势-言语组合的频率上的诊断特异性可变性。这些发现表明，即使父母以相似的方式模仿手势，儿童产生每种类型的手势的数量在很大程度上反映了特定于诊断的能力。
