The goal of this research was to examine the nonverbal communication competence of 18-48-month-old Down syndrome children. The results indicated that Downs children displayed strengths and weaknesses in nonverbal communication skills. Relative to MA matched normal children, they displayed a significant strength in nonverbal social interaction skills. However, they also displayed a significant deficit in nonverbal requests for objects or assistance with objects compared to normals. This pattern of strength and weakness in nonverbal skills appeared to be specific to Down syndrome since this pattern was not displayed by a comparison sample of non-Downs mentally retarded children. Nonverbal object-requesting skill was also significantly associated with a measure of expressive language in the Downs sample. This relation was notable because the Downs children also displayed a deficit in expressive language. Thus, the results of this study suggest that a deficit in expressive language is associated with a deficit in earlier-developing nonverbal requesting skill among Down syndrome children.
本研究的目的是考察18至48个月大的唐氏综合征儿童的非言语沟通能力。结果表明，唐氏综合征儿童在非言语沟通技能方面有优势和劣势。相对于心理年龄匹配的正常儿童，他们在非言语社交互动技能方面表现出显著优势。然而，与正常儿童相比，他们在通过非言语方式索要物品或寻求物品帮助方面也表现出显著不足。非言语技能的这种优势和劣势模式似乎是唐氏综合征所特有的，因为非唐氏综合征的智障儿童对照样本并未表现出这种模式。在唐氏综合征样本中，非言语索要物品技能也与表达性语言的一项测量指标显著相关。这种关系值得注意，因为唐氏综合征儿童在表达性语言方面也存在不足。因此，本研究结果表明，唐氏综合征儿童表达性语言的不足与早期发展的非言语索要技能的不足有关。
