The evidence on the effect of age on the receptive and expressive language skills of individuals with Down syndrome is inconclusive. Recent research highlights the relevance of having tools to detect age-related changes in language skills.
Data were collected on 45 adults with Down syndrome. All were assessed with the Peabody test, token test, verbal fluency tasks and an expressive language sample.
Scores on token and Peabody showed a decline in older adults, whereas no significant effect of age was observed for expressive language measures. A quadratic regression confirmed the association between age and receptive language measures. Highly significant associations were also found between the performance on receptive and expressive language measures.
Receptive language skills are more age-sensitive than the expressive language skills. In addition to expressive language skills, receptive language skills should be measured because they show age associated changes not observed in expressive language.
关于年龄对唐氏综合征患者接受性和表达性语言技能影响的证据尚无定论。最近的研究强调了拥有检测语言技能中与年龄相关变化的工具的重要性。
收集了45名成年唐氏综合征患者的数据。所有人都接受了皮博迪测试、代币测试、语言流畅性任务和一个表达性语言样本评估。
代币测试和皮博迪测试的分数在老年人中呈下降趋势，而表达性语言测量未观察到年龄的显著影响。二次回归证实了年龄与接受性语言测量之间的关联。在接受性和表达性语言测量的表现之间也发现了高度显著的关联。
接受性语言技能比表达性语言技能对年龄更敏感。除了表达性语言技能外，还应测量接受性语言技能，因为它们显示出在表达性语言中未观察到的与年龄相关的变化。
