语法特异性语言障碍（G-SLI）被认为是语言障碍的一个独特亚型。我们评估了一个大样本的双胞胎之间的7和13岁的语言理解测试敏感的G-SLI。该样本包括37对同性双胞胎，其中一对或两对双胞胎中存在语言障碍（LI），104对双胞胎来自普通人群。LI患者的错误数量和模式重复了先前G-SLI研究的结果。G-SLI的定性标志物来自测试。在144名有完整数据的儿童中，2名儿童在所有五项标志物上得分均为阳性，9名儿童在五项标志物中的四项上得分为阳性。大多数犯语法错误的儿童G-SLI的特点是在其他领域的共同发生的赤字。这些结果对将这种疾病视为全或无模块缺陷的理论提出了质疑。
Grammatical specific language impairment (G-SLI) has been proposed as a distinct subtype of language impairment. We assessed a large sample of twins between the ages of 7 and 13 years on language comprehension tests sensitive to G-SLI. The sample included 37 same-sex twin pairs selected for the presence of language impairment (LI) in one or both twins and 104 twin pairs from the general population. The number and patterns of errors in those with LI replicated findings from previous studies of G-SLI. Qualitative markers of G-SLI were derived from the tests. Out of 144 children for whom complete data were available, 2 scored positive on all five markers and 9 scored positive on four of the five markers. Most children who made grammatical errors characteristic of G-SLI had co-occurring deficits in other areas. These results raise questions for theories that treat this disorder as an all-or-none modular deficit.
