先前的研究已经证明了语言缺陷的家族聚集性。然而，研究人员通常无法区分语言障碍儿童的亚组。本研究使用问卷数据来评估一组患有发育性表达语言迟缓（ELD）的幼儿和正常发育儿童样本的言语、语言和学校问题的家族史。与之前对语言和言语问题的研究相比，没有发现 ELD 具有很强的家庭因素。此外，家族史并不能预测 ELD 儿童后来的语言发展。这些发现反对 ELD 的遗传和家族原因，并证明了区分早期语言问题亚型的重要性。
Familial aggregation of language deficits has been demonstrated in previous studies. However, researchers have typically failed to differentiate subgroups of language-impaired children. The present study used questionnaire data to assess the family history of speech, language, and school problems in a group of young children with developmental expressive language delay (ELD) and in a sample of normally developing children. In contrast to previous studies of language and speech problems, no strong familial component of ELD was found. Further, family history was not predictive of later language development in ELD children. These findings argue against genetic and familial causes of ELD and attest to the importance of differentiating subtypes of early language problems.
