Learning-based cognitive control in ADHD: a multicentric study

Area of Science:

• Neuroscience
• Developmental Psychology
• Cognitive Psychology

Background:

• Cognitive control (CC) adaptation to contextual regularities is underexplored in children with ADHD.
• This study examines learning-based CC in children with ADHD under varying cognitive loads.

Purpose of the Study:

• To investigate if children with ADHD exhibit intact learning-based CC.
• To determine the impact of increased cognitive demands on CC in ADHD.

Main Methods:

• A multicentric study involving 145 children with ADHD and 97 typically developing (TD) children (ages 7-14).
• Two tasks (Flanker, cued go-noGo) with List-Wide Proportion Congruency (LWPC) manipulation to vary contextual predictability.
• Analysis of reaction times, accuracy, and associations with neuropsychological and questionnaire measures.

Main Results:

• Children with ADHD showed similar LWPC effects to TD peers in the low-demand Flanker task.
• In the high-demand cued go-noGo task, children with ADHD had less efficient RT modulation and speed-accuracy trade-off adaptation.
• Neuropsychological composite scores predicted task adaptation, but questionnaire data did not.

Conclusions:

• Learning-based CC is preserved in children with ADHD in simple contexts but impaired under complex, multi-demand conditions.
• Neuropsychological performance is a key factor in group differences in CC adaptation.
• Findings support the use of ecologically valid paradigms and tailored interventions for complex CC challenges in ADHD.
