Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? Children with ADHD-C perform worse than controls on both STM and CE components of visuospatial WM. → Dovis 2015
q3 i? Children with ADHD-I perform worse than controls on CE but not on STM. → Dovis 2015

This is a controlled experimental comparison reported in the study of 27 children with ADHD-I, 70 children with ADHD-C, and 40 typically developing controls aged 9-12. The article states that "In children with ADHD-C, both STM and the CE seem impaired, and together with motivational impairments, give rise to their deficits in visuospatial WM." In contrast, for ADHD-I the article reports that "STM performance of children with ADHD-I was, in contrast to that of children with ADHD-C, not different from controls." No effect sizes are printed in the supplied text, so impact is null.
"In children with ADHD-C, both STM and the CE seem impaired, and together with motivational impairments, give rise to their deficits in visuospatial WM."
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 — related
- Both ADHD subtypes show equally pronounced motivational deficits that impair visuospatial STM and WM performance — related
- High reinforcement improves STM and WM performance in both ADHD subtypes but not in controls — related
- Affect recognition deficits were not found unanimously across ADHD groups, suggesting a nuanced subtype-specific pattern — related
- 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 — related
- Visuospatial working memory and short-term memory impairments are most prevalent in children with ADHD-C relative to ADHD-I and typically developing controls — related
- In the ADHD-I restrictive subtype, visuospatial WM impairments are more prevalent than in controls but STM impairments are not — related
- The majority of children with ADHD-C is impaired on visuospatial working memory — related
