The aim of the study was to examine the profiles of children with a family history (FH+) of language-learning impairments (LLI) and a control group of children with no reported family history of LLI (FH-) and identify which language constructs (receptive or expressive) and which ages (2 or 3 years) are related to expressive and receptive language abilities, phonological awareness, and reading abilities at ages 5 and 7 years. Participants included 99 children (40 FH+ and 59 FH-) who received a standardized neuropsychological battery at 2, 3, 5, and 7 years of age. As a group, the FH+ children had significantly lower scores on all language measures at 2 and 3 years, on selected language and phonological awareness measures at 5 years, and on phonological awareness and nonword reading at 7 years. Language comprehension at 3 years was the best predictor of later language and early reading for both groups. These results support past work suggesting that children with a positive family history of LLI are at greater risk for future language and reading problems through their preschool and early school-age years. Furthermore, language comprehension in the early years is a strong predictor of future language-learning status.
该研究的目的是调查有语言学习障碍家族史(FH+)的儿童以及未报告有语言学习障碍家族史的对照组儿童(FH-)的概况,并确定哪些语言结构(接受性或表达性)以及哪些年龄(2岁或3岁)与5岁和7岁时的表达性和接受性语言能力、语音意识及阅读能力相关。研究参与者包括99名儿童(40名FH+和59名FH-),他们在2岁、3岁、5岁和7岁时接受了标准化的神经心理测试。总体而言,FH+组儿童在2岁和3岁时的所有语言测试中得分显著较低,在5岁时的部分语言和语音意识测试中得分较低,在7岁时的语音意识和非词阅读测试中得分较低。3岁时的语言理解能力是两组儿童后期语言能力和早期阅读能力的最佳预测指标。这些结果支持了以往的研究,表明有语言学习障碍家族史阳性的儿童在学前和学龄早期出现未来语言和阅读问题的风险更高。此外,早年的语言理解能力是未来语言学习状况的有力预测指标。
