The ability to select an idea from an array of competing options is critical for successful propositional language production, and deficient contributes to propositional language impairments in clinical populations. We investigate whether three clinical idea selection tasks are sensitive to selection demands in neurologically unimpaired adults, and whether performance relates to age. 154 neurologically normal adults aged 18-89 years completed a neuropsychological baseline and three idea selection tasks. Stimuli either activated a dominant response or multiple competing response options. All three idea selection tasks were sensitive to selection demands in terms of reaction times but not errors. Older age was associated with greater effects of selection demands on Sentence Completion task performance only. Exploratory analyses revealed a potential role of executive functioning. Overall, we demonstrate that clinical idea selection tasks are sensitive to idea selection demands in a non-clinical sample, and show some age-related differences in performance.
从一系列竞争选项中选择一个想法的能力对于成功的命题语言产生至关重要，而能力缺陷导致临床人群的命题语言障碍。我们研究了三个临床的想法选择任务是否对神经健全成年人的选择需求敏感，以及表现是否与年龄有关。154 名神经正常的成年人年龄在 18-89 岁之间，完成了神经心理学基线和三个想法选择任务。刺激物要么激活了一个主导反应，要么激活了多个竞争反应选项。所有三个想法选择任务在反应时间方面都对选择需求敏感，但在错误方面不敏感。只有在句子完成任务中，年龄较大与选择需求对表现的影响更大有关。探索性分析表明，执行功能可能起作用。总的来说，我们证明了临床的想法选择任务对非临床样本中的选择需求敏感，并显示了一些与年龄相关的表现差异。
