Lateral asymmetries in finger-tapping were compared in right-handed adolescents and young adults with and without Down syndrome in order to examine cerebral specialization in the Down syndrome group. Finger-tapping data revealed that subjects with Down syndrome performed more slowly than did control subjects and failed to show a right-hand tapping advantage. Although the latter finding suggests that individuals with Down syndrome are less lateralized for sequential processing, they exhibited the same pattern of tapping variability as did control subjects; i.e., they were more variable when finger-tapping with their left hands.
为了研究唐氏综合征组的大脑功能特化，对患有和未患有唐氏综合征的右利手青少年及年轻成年人的手指敲击侧向不对称性进行了比较。手指敲击数据显示，唐氏综合征患者的敲击速度比对照组慢，且未表现出右手敲击优势。尽管后一发现表明唐氏综合征患者在序列处理方面的大脑功能定位化程度较低，但他们与对照组受试者表现出相同的敲击变异性模式；也就是说，他们用左手进行手指敲击时变异性更大。
