Does sensorimotor dysfunction underlie reading impairment? To investigate this question, a battery of literacy, phonology, auditory, visual, and motor tests were administered to age- and ability-matched groups of dyslexic, autistic, and control children. As in previous studies, only a subset of the dyslexic children had sensory and/or motor impairments, whilst some dyslexics were entirely spared, suggesting that sensorimotor impairments are not necessary to cause reading disability. A subset of autistic children was also found to have sensorimotor impairments; however, some of these children did not have reading problems, suggesting that sensorimotor impairments are not sufficient to cause reading disability. We conclude that sensorimotor and reading impairments are doubly dissociable. Sensorimotor impairments do not seem to be the cause of reading disability, but can be seen as nonspecific markers for developmental disorder.
感觉运动功能障碍是否是阅读障碍的基础？为了研究这个问题，我们对阅读障碍、自闭症和对照组儿童进行了一系列的读写、语音、听觉、视觉和运动测试。与之前的研究一样，只有一部分阅读障碍儿童存在感觉运动障碍，而一些阅读障碍儿童则完全没有，这表明感觉运动障碍并不是导致阅读障碍的必要条件。也有一部分自闭症儿童存在感觉运动障碍；然而，这些儿童中也有一些没有阅读问题，这表明感觉运动障碍也不足以导致阅读障碍。我们的结论是，感觉运动和阅读障碍是双重分离的。感觉运动障碍似乎不是阅读障碍的原因，但可以被视为发育障碍的非特异性标志物。
