ABSTRACT Based on a representational perspective, this paper examines executive functioning in Down syndrome. Sixteen young adults with Down syndrome, 16 mental age- and 16 age-matched controls were compared on script sequencing and sorting tasks. Participants were asked to reestablish the sequential structure of script actions given with or without irrelevant actions. Impairments in script information processing were observed only in young adults with Down syndrome, who performed more slowly than controls, making mistakes in ordering actions, but rejecting aberrant elements. These data are consistent with the view that Down syndrome impairs the syntactic but not semantic dimension of script representation.

对患有唐氏综合症的年轻人执行功能障碍的代表性方法

摘要 基于代表性的观点，本文研究了唐氏综合症的执行功能。16 名患有唐氏综合症的年轻人、16 名心理年龄相匹配的对照组和 16 名年龄匹配的对照组在脚本排序和排序任务上进行了比较。参与者被要求重新建立有或没有无关动作的脚本动作的顺序结构。仅在患有唐氏综合症的年轻人中观察到脚本信息处理的障碍，他们的表现比对照组慢，在命令动作时犯错误，但拒绝异常元素。这些数据与唐氏综合症损害脚本表示的句法而非语义维度的观点一致。
