Subclaims¶
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? In ADHD-I, WM impairments were more prevalent than in controls, whereas STM impairments were not more common than in controls. → S. Dovis 2015

q3 · i? · associational · r?
Group comparison of 27 children with ADHD-I (restrictive subtype) against 62 typically developing controls on visuospatial WM and STM tasks. The abstract states "In ADHD-I, only WM impairments, not STM impairments, were more prevalent than in controls."
"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
- Impairment on WM, STM, and/or motivation is associated with more inattention symptoms, medication use, and lower IQ scores — 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
- 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
- The majority of children with ADHD-C is impaired on visuospatial working memory — related
