Dovis, S., Van der Oord, S., Wiers, R.W., & Prins, P.J.M. (2015). ADHD subtype differences in reinforcement sensitivity and visuospatial working memory. Journal of Clinical Child and Adolescent Psychology, 44(5), 859-874. https://doi.org/10.1080/15374416.2014.895940

q3 · i? · causal · r?

This is the study's motivational-deficit conclusion, drawn from the experiment in which high reinforcement improved STM and WM performance in both ADHD subtypes but not in typically developing controls. The article states that "Both subtypes have equally pronounced motivational deficits, which have detrimental effects on their visuospatial STM and WM performance." The equal benefit of high reinforcement across subtypes is the basis for the claim of equally pronounced motivational deficits. No effect sizes are printed in the supplied text, so impact is null.

"Both subtypes have equally pronounced motivational deficits, which have detrimental effects on their visuospatial STM and WM performance."

Discussion¶

Related Claims¶

• STM and WM performance is worse in ADHD-C than in ADHD-I, while CE-related performance does not differ between subtypes — reports the opposite
• Children with ADHD-C show impaired visuospatial STM and CE relative to typically developing controls, whereas children with ADHD-I show impaired CE but intact STM — related
• High reinforcement improves STM and WM performance in both ADHD subtypes but not in controls — related
• Cognitive deficits in children with ADHD are not permanent neuropsychological impairments and cognitive capacity can be modulated by motivation — a broader claim this one bears on
• Diagnostic validity analyses yield results similar to the prevalence findings for WM, STM, and motivational impairments — related
• Impairment on WM, STM, and/or motivation is associated with more inattention symptoms, medication use, and lower IQ scores — related
• Memory and motivation represent independent neuropsychological domains in children with ADHD — reports the opposite
• Motivational impairments in reinforcement sensitivity are uncommon (22% impaired) and equally prevalent in both ADHD subtypes — related
