Abstract: OBJECTIVE: Slower and more variable reaction time is one of the most prominent cognitive signatures in childhood attention-deficit/hyperactivity disorder (ADHD). However, standard use of tasks that involve motor responses to index "speed" potentially confounds fine-motor coordination with central cognitive processing speed. One promising alternative is a vocal articulation task, which provides a measure of speeded performance that is independent of fine-motor coordination. METHOD: = 119). RESULTS: was also greater among children with ADHD, and the greater variance was not fully explained by individual differences in working memory. CONCLUSIONS: Results highlight the importance of adopting analytic methods that can more accurately describe performance. (PsycInfo Database Record (c) 2025 APA, all rights reserved).
