The handedness and sex of 4- and 5-year-old children with developmental language disorders were studied through a comparison of language disordered children and a normal control group and through a comparison of six linguistically homogeneous subgroups of language disordered children. Differences between the handedness of a generalized language disordered group and a normal control group were not found, possibly due to the multiple etiologies of developmental language disorders. Children with severe language disorders, however, were non-right-handed more often than children with mild language disorders. Furthermore, certain types of linguistic deficits were associated with non-right-handedness, whereas age and cognitive abilities were not. Males were more often language disordered than females; however, sex ratios did not significantly differ among the subgroups, possibly due to the small number of language disordered females in this study. Implications for cerebral laterality in developmental language disorders are discussed.
通过将发育性语言障碍儿童与正常对照组进行比较，以及对发育性语言障碍儿童的六个语言同质亚组进行比较，研究了4岁和5岁发育性语言障碍儿童的用手习惯和性别。未发现广义语言障碍组与正常对照组在用手习惯上存在差异，这可能是由于发育性语言障碍的病因多种多样。然而，严重语言障碍儿童比轻度语言障碍儿童更常使用非右手。此外，某些类型的语言缺陷与非右手习惯有关，而年龄和认知能力则无关。男性比女性更常出现语言障碍；然而，各亚组之间的性别比例没有显著差异，这可能是由于本研究中语言障碍女性数量较少。文中讨论了发育性语言障碍中大脑半球偏侧性的相关影响。
