Objective

We aimed to understand the association between MW frequency and clinical measures, context regulation of MW and group differences in task performance.

Method

27 adults with ADHD and 29 controls performed tasks manipulating demand on working memory and sustained attention, and recorded their MW frequency using probes.

Results

A significant association between MW frequency and the clinical measures was demonstrated. Along with increased MW frequency, individuals with ADHD reported decreasing MW frequency during increasing demands on working memory (context regulation), but not on sustained attention (deficient context regulation). Controls, however, maintained continuous task focus across all conditions. Group differences in task performance were no longer significant after adding MW frequency as a covariate.

Conclusion

Deficient context regulation during increasing demands on sustained attention suggests that sustained attention deficits may play a more important role in regulation of MW in ADHD. MW frequency might also underpin performance deficits in ADHD.

客观的

我们旨在了解 MW 频率与临床测量、MW 的背景调节和任务绩效的组差异之间的关联。

方法

27 名患有 ADHD 的成年人和 29 名对照组执行了操纵对工作记忆和持续注意力的需求的任务，并使用探针记录了他们的 MW 频率。

结果

证明了 MW 频率与临床测量之间的显着关联。随着 MW 频率的增加，患有 ADHD 的人报告说，在对工作记忆（情境调节）的需求增加期间，MW 频率降低，但在持续注意力（缺乏情境调节）方面没有。然而，控制在所有条件下保持持续的任务重点。添加 MW 频率作为协变量后，任务绩效的组间差异不再显着。

结论

在对持续注意力的需求增加期间缺乏背景调节表明持续注意力缺陷可能在 ADHD 的 MW 调节中发挥更重要的作用。MW 频率也可能是 ADHD 表现缺陷的基础。
