12名患有和未患有唐氏综合征（DS）的儿童进行了8项失用症电池的子测试，以确定在何种条件下DS儿童难以执行代表性和非代表性的手势。患有DS的参与者还完成了两耳分听测试。DS参与者在失用症电池的各个方面表现得和对照组参与者一样好，除了一个子测试，在这个子测试中，他们被要求从口头指令中使用手势工具。这表明患有DS的儿童在口头指令后很难从记忆中产生动作。如果有足够的背景或视觉演示，DS儿童的表现与其他参与者相似。同样，两耳分听优势在组内也有很大的差异。在两耳分听测试中，左耳优势更大的参与者在模仿测试中犯的错误比右耳优势更大的参与者多，模仿测试也包括语言成分。
Twelve children with and without Down syndrome (DS) performed eight subtests of an apraxia battery to determine under what conditions children with DS had difficulty performing representational and nonrepresentational gestures. Participants with DS also completed a dichotic listening test. Participants with DS performed just as well as control participants on all aspects of the apraxia battery except a subtest in which they were required to pantomime tool use from verbal instruction. This suggests that children with DS have difficulty generating an action from memory following verbal instruction. Given the sufficient context or visual demonstration, children with DS performed similar to the other participants. As well, there was a great deal of within-group variability for dichotic listening ear advantage. Participants with a greater left ear advantage on the dichotic listening test committed more errors on an imitation test that also included a verbal component than participants with a greater right ear advantage.
