This study examined the contribution of the temporal dynamics of two cognitive control mechanisms-inhibitory control (IC) and working memory (WM)-to emotion dysregulation (ED) in attention-deficit/hyperactivity disorder (ADHD) in ecological settings.
One hundred twenty-two participants (age 18-33 years; 60 with ADHD) reported their ED at baseline, followed by a 5-day ecological momentary assessment (EMA) study, with short behavioral IC and WM tasks performed five times/day.
For IC, mean and lability of performance over EMA significantly accounted for differences in ED but not baseline performance. For WM, both baseline and mean of EMA, but not EMA lability, accounted for ED variance. ADHD status further contributed to the explained variance of ED.
Our results support the contribution of dynamic IC processes to ED in ADHD, in addition to WM performance level, and highlight the importance of dynamic and ecological investigation of different cognitive control components.
本研究考察了两种认知控制机制——抑制控制（IC）和工作记忆（WM）——在生态环境中对注意力缺陷/多动障碍（ADHD）患者情绪失调（ED）的时间动态变化的贡献。
122 名参与者（年龄 18-33 岁；60 名 ADHD 患者）在基线时报告了他们的 ED，随后进行了为期 5 天的生态瞬时评估（EMA）研究，每天进行 5 次简短的行为 IC 和 WM 任务。
对于 IC，EMA 期间的表现均值和变异性显著解释了 ED 的差异，但不包括基线表现。对于 WM，不仅 EMA 的基线和均值，而且 EMA 的变异性，都解释了 ED 的方差。ADHD 状态进一步解释了 ED 的方差。
我们的研究结果支持动态 IC 过程对 ADHD 患者 ED 的贡献，除了 WM 表现水平，还强调了对不同认知控制成分的动态和生态研究的重要性。
