Previous work has noted that some children with autism spectrum disorder (ASD) display weaknesses in receptive vocabulary relative to expressive vocabulary abilities. The current study extended previous work by examining the receptive-expressive vocabulary profile in boys with idiopathic ASD and boys with concomitant ASD and fragile X syndrome (ASD + FXS). On average, boys with ASD + FXS did not display the same atypical receptive-expressive profile as boys with idiopathic ASD. Notably, there was variation in vocabulary abilities and profiles in both groups. Although we did not identify predictors of receptive-expressive differences, we demonstrated that nonverbal IQ and expressive vocabulary positively predicted concurrent receptive vocabulary knowledge and receptive vocabulary predicted expressive vocabulary. We discuss areas of overlap and divergence in subgroups of ASD.
先前的研究指出，一些患有自闭症谱系障碍（ASD）的儿童在接受性词汇方面相对于表达性词汇能力存在弱点。当前的研究通过检查患有特发性ASD的男孩以及患有ASD合并脆性X综合征（ASD+FXS）的男孩的接受性-表达性词汇概况，扩展了先前的研究。平均而言，患有ASD+FXS的男孩没有表现出与患有特发性ASD的男孩相同的非典型接受性-表达性概况。值得注意的是，两组在词汇能力和概况方面都存在差异。虽然我们没有确定接受性-表达性差异的预测因素，但我们证明了非言语智商和表达性词汇正向预测同时期的接受性词汇知识，而接受性词汇则预测表达性词汇。我们讨论了ASD亚组中的重叠和差异领域。
