We examined the correlations between receptive language level and performance on indices of nonverbal cognitive functioning for 20 persons with mental retardation and for 20 children without mental retardation matched to them on nonverbal MA. The correlations suggested that the retarded group focused on the formal, sequential properties of language. The correlations also suggested that the nondisabled group placed less emphasis on the formal, sequential properties of language and more on semantic, conceptual properties. These differences in approach may explain why the persons with mental retardation did poorly on the task of understanding spoken language compared to the children without mental retardation.
我们考察了20名智力迟钝者以及20名在非言语心理年龄上与之匹配的无智力迟钝儿童的接受性语言水平与非言语认知功能指标表现之间的相关性。这些相关性表明，智力迟钝组关注语言的形式和顺序特性。相关性还表明，非残疾组较少强调语言的形式和顺序特性，而更多地强调语义和概念特性。这些方法上的差异可能解释了为什么智力迟钝者在理解口语任务上比无智力迟钝的儿童表现更差。
