The predictive ability of early consonant inventory and intentional communication on later expressive language was examined in 36 boys with fragile X syndrome (FXS). Autism symptom severity was included as a potential moderator. Participants were visited in their homes twice over a 6-year period, and mother-child interactions were videotaped, coded, and transcribed behavior by behavior. Consonant inventory and concurrent autism symptom severity were predictive of later number of different words, as was the interaction between the two. Intentional communication was not predictive of number of different words. These findings provide additional specific evidence for differences in foundational language abilities associated with autism symptom severity in boys with FXS. Clinical implications are discussed.
本研究旨在探讨 36 名脆性 X 综合征（FXS）男孩的早期辅音音位习得能力和有意沟通能力对其后续表达性语言发展的预测作用，并分析自闭症症状严重程度是否对这一预测作用具有调节效应。研究人员在 6 年的时间里两次登门拜访这些家庭，并对母子互动进行录像、编码和逐句转录。研究结果发现，辅音音位习得能力和同期自闭症症状严重程度可预测男孩后续不同词汇量的习得，二者的交互作用也具有预测力。然而，有意沟通能力对词汇量习得并无预测力。本研究为 FXS 男孩的自闭症症状严重程度与基础性语言能力差异提供了进一步的具体证据。研究还讨论了相关的临床意义。
