本研究的目的是调查（a）是否有阅读障碍的家庭中的儿童更容易表现出语言发展的延迟比儿童没有家庭风险和（B）是否延迟的表达性语言（晚说话）预测以后的语言发展。我们纵向分析了200名儿童在14个月、24个月、30个月和42个月时的语言发展，并在14个月时评估了他们的符号游戏。一半的儿童（N = 106）来自有阅读障碍病史的家庭（阅读障碍风险[DR]组），其他儿童作为年龄匹配的对照组。父母的报告和结构化的测试被用来评估儿童的接受和表达的语言和象征性的发挥。两组在接受性语言、象征性游戏或贝利MDI上没有差异。然而，这些群体在表达语言的措施上存在分歧。对照组在2岁时的最大句子长度和3.5岁时的物体命名和屈折形态技能高于DR组。在2.5岁时，对儿童接受性和表达性语言的预测贡献最大。儿童的风险状况并没有帮助接受语言，但提供了显着的贡献，他们的表达语言在3.5年，即使在方差与父母的教育和儿童以前的语言技能得到控制。在3.5岁时，DR组的晚说话者在接受性和表达性语言方面与DR组的其他成员不同，尽管在对照组中，有晚说话史的儿童在年龄水平的期望下表现。研究结果表明，有阅读障碍家族风险和有晚起说话史的儿童比没有阅读障碍家族风险的儿童在语言习得方面延迟的风险更高。
The purposes of this study were to investigate (a) whether children in families with a positive history of dyslexia were more likely to show delays in language development than children without family risk and (b) whether a delayed onset of expressive language (late talking) predicted later language development. We analyzed the language development of 200 children longitudinally at 14, 24, 30, and 42 months and assessed their symbolic play at 14 months. Half of the children (N = 106) were from families with a history of dyslexia (the Dyslexia Risk [DR] group), and other children served as age-matched controls. Parental reports and structured tests were used to assess children's receptive and expressive language and symbolic play. No differences emerged between the two groups in receptive language, symbolic play, or on the Bayley MDI. The groups, however, diverged in expressive language measures. The maximum sentence length at 2 years and object naming and inflectional morphology skills at 3.5 years were higher for the control group than for the DR group. Reynell receptive score at 2.5 years provided the greatest unique contribution to the prediction of the children's receptive and expressive language. Children's risk status did not contribute to receptive language, but provided a significant contribution to their expressive language at 3.5 years, even after the variance associated with parental education and children's previous language skills was controlled. Late talkers in the DR group differed from the other members of the DR group in both receptive and expressive language at 3.5 years, although in the control group children with a late-talking history performed at age-level expectations. The findings suggest that children with a familial risk for dyslexia and with a history of late talking are at higher risk for delays in language acquisition than children without the familial risk for dyslexia.
