背景技术背景：虽然唐氏综合征的行为表型被描述为涉及视觉空间处理和社交能力的相对优势，以及语言技能和运动规划的相对劣势，但这种优势和劣势的表型模式的早期出现尚未得到充分探讨。方法：在本研究中，我们比较了18名2 - 3岁唐氏综合征患儿和19名2 - 3岁的MA匹配对照组的表现，混合性发育障碍的奥尔兹和MA匹配的24名儿童的对照组，两个发展措施：马伦量表的早期学习和葡萄园适应行为量表的典型发展。虽然唐氏综合征的特异性是绝大多数时候，都没有明显的迹象。结果表明，这项研究中患有唐氏综合征的幼儿确实表现出了与年龄较大的儿童和年轻人相似的相对优势和弱点。唐氏综合症。这种模式包括相对较强的社会技能，较弱的表达语言，以及运动协调性差。当这种模式的优势和劣势相比，两个对照组的发展概况，社会化优势区分唐氏综合征组的混合发育障碍组。
BACKGROUND: Though the Down syndrome behavioural phenotype has been described as involving relative strengths in visuo-spatial processing and sociability, and relative weaknesses in verbal skills and motor planning, the early emergence of this phenotypic pattern of strengths and weaknesses has not yet been fully explored.METHOD: In this study, we compared the performance of eighteen 2 to 3-year-olds with Down syndrome to an MA-matched comparison group of nineteen 2 to 3-year-olds with mixed developmental disabilities, and an MA-matched comparison group of 24 children with typical development on two developmental measures: the Mullen Scales of Early Learning and the Vineland Adaptive Behaviour Scales.RESULTS: While the specificity of the Down syndrome profile was (for the most part) not yet evident, results showed that toddlers with Down syndrome in this study did show emerging areas of relative strength and weakness similar to that which has been described in older children and young adults with Down syndrome. This pattern included relatively stronger social skills, weaker expressive language, and poor motor coordination. When this pattern of strengths and weaknesses was compared to the developmental profiles of the two comparison groups, socialisation strengths differentiated the Down syndrome group from the mixed developmental disabilities group.
