The left hemisphere is usually predominant in manual skills and language, suggesting a link between hand dominance and language. Studies of autism spectrum disorder show atypical handedness; however, few have examined language-handedness associations. Handedness, assessed by task performance, and standardized receptive and expressive language tests were completed in 110 autism spectrum disorder children (96 boys; M age = 8.3 years, SD = 3.8) and 45 typically developing children (37 boys; M age = 8.6 years, SD = 4.3), 3 to 17 years of age. The autism spectrum disorder group had a lower handedness score (was less strongly lateralized) than the control group. In the autism spectrum disorder group, there was a small effect of handedness on language; right-handers had better language than non-right-handers. Results suggest poorer language prognosis may be associated with left- or mixed-handedness in autism spectrum disorder.
左半球通常在手工技能和语言方面占主导地位，这表明用手习惯与语言之间存在联系。对自闭症谱系障碍的研究显示出非典型的用手习惯；然而，很少有研究考察语言与用手习惯之间的关联。通过任务表现评估用手习惯，并对110名自闭症谱系障碍儿童（96名男孩；平均年龄 = 8.3岁，标准差 = 3.8）和45名发育正常的儿童（37名男孩；平均年龄 = 8.6岁，标准差 = 4.3），年龄在3至17岁之间，进行标准化的接受性和表达性语言测试。自闭症谱系障碍组的用手习惯得分低于对照组（偏侧化程度较低）。在自闭症谱系障碍组中，用手习惯对语言有微小影响；右利手者的语言能力优于非右利手者。结果表明，在自闭症谱系障碍中，较差的语言预后可能与左利手或混合利手有关。
