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? High reinforcement (feedback + 10 euros) improved STM and WM performance in both ADHD-C and ADHD-I children. → Dovis 2015
q3 i? High reinforcement did not improve CE-related performance in either subtype. → Dovis 2015

This is the reinforcement-manipulation result of the experiment comparing a standard level (feedback only) with a high level of reinforcement (feedback + 10 euros) in 27 children with ADHD-I, 70 with ADHD-C, and 40 controls. The article reports that "High reinforcement improved STM and WM performance in both subtypes but not in controls" and that "This improvement was equally pronounced in both subtypes." It also reports that "High reinforcement did not improve CE-related performance." No effect sizes are printed in the supplied text, so impact is null.
"High reinforcement improved STM and WM performance in both subtypes but not in controls. This improvement was equally pronounced in both subtypes. High reinforcement did not improve CE-related performance."
Discussion¶
Related Claims¶
- Both ADHD subtypes show equally pronounced motivational deficits that impair visuospatial STM and WM performance — 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
- Diagnostic validity analyses yield results similar to the prevalence findings for WM, STM, and motivational impairments — related
- Memory and motivation represent independent neuropsychological domains in children with ADHD — reports the opposite
- 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
