表达性语言迟缓和执行功能障碍在患有唐氏综合症 (DS) 的青少年中很常见。言语流畅性是研究这些结构的一种方法。我们检查了语义言语流畅性反应，以确定反应生成的模式和编码簇形成的心理测量特性。参与者为 97 名年龄在 6 岁至 19 岁之间的 DS 儿童和青少年。语义言语流畅性任务在两个时间点进行，相隔两周。当使用传统分类或上下文分类进行编码时，观察到响应表现的异质性。总体而言，传统分类中的切换数量多于上下文分类。这意味着参与者没有使用传统（传统）类别来组织他们的语义言语流畅性反应，但可能一直在使用语境策略。然而，开关数量和簇大小变量的重测可靠性较差到中等，这表明无论使用何种策略，参与者在两周的测试间隔内都无法保持一致的表现。因此，作为执行控制措施的传统和上下文集群和转换可能并不适合所有患有 DS 的个体，并且需要额外的关注来确定响应编码在该人群中的效用。
Expressive language delays and executive functioning challenges are common in youth with Down syndrome (DS). Verbal fluency is one method to investigate these constructs. We examined semantic verbal fluency responses to determine patterns in response generation and the psychometric properties of coded cluster formations. Participants were 97 children and adolescents with DS ranging in age from 6 to 19 years old. The semantic verbal fluency task was administered at two time points, two weeks apart. Heterogeneity in performance was observed for responses when coded either with conventional or contextual classifications. Overall, the number of switches in conventional classifications was greater than contextual classifications. This implies that participants did not use traditional (conventional) categories to organize their semantic verbal fluency responses, but may have been using contextual strategies. However, the number of switches and cluster size variables had poor to moderate test–retest reliability, which indicated that participants did not stay consistent with their performance over the two-week testing interval, regardless of the strategies used. Therefore, conventional and contextual clusters and switches as a measure of executive control may not be appropriate for all individuals with DS and additional attention is warranted to determine the utility of response coding in this population.
