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? WM and STM impairments were most prevalent in the ADHD-C subtype compared with ADHD-I and typically developing controls. → S. Dovis 2015

S. Dovis, S. van der Oord, H.M. Huizenga, R.W. Wiers, P.J.M. Prins. (2015). Prevalence and diagnostic validity of motivational impairments and deficits in visuospatial short-term memory and working memory in ADHD subtypes.

q3 · i? · associational · r2
Cross-sectional group comparison of 86 children with ADHD-C, 27 with ADHD-I, and 62 typically developing controls aged 8-12 on visuospatial WM and STM tasks. The abstract reports "WM and STM impairments were most prevalent in ADHD-C" with subtype-specific patterns for STM.
"WM and STM impairments were most prevalent in ADHD-C. In ADHD-I, only WM impairments, not STM impairments, were more prevalent than in controls."
Discussion¶
Related Claims¶
- 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
- The majority of children with ADHD-C is impaired on visuospatial working memory — related
- Memory and motivation represent independent neuropsychological domains in children with ADHD — related
- In the ADHD-I restrictive subtype, visuospatial WM impairments are more prevalent than in controls but STM impairments are not — related
- 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
- STM and WM performance is worse in ADHD-C than in ADHD-I, while CE-related performance does not differ between subtypes — related
- Meta-analyses establish that ADHD is associated with poorer performance on tasks measuring inhibition, working memory, planning, and vigilance in children, with overall similar impairment patterns in adults and a strong association with reaction time variability — a broader claim this one bears on
