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 i3 Children with ADHD showed significantly higher TBR than TD children at each controlled midline location, with medium-to-large effects. → Sebastian Skalski 2021
Evidence¶
Sebastian Skalski 2021¶
Sebastian Skalski, Grzegorz Pochwatko, Robert Balas. (2021). Impact of Motivation on Selected Aspects of Attention in Children with ADHD. Child Psychiatry & Human Development. https://doi.org/10.1007/s10578-020-01042-0
q3 · i3 · causal · r1
Resting-state EEG in the group comparison of 30 children with ADHD and 30 TD children; Student's t-tests showed significant TBR differences, with printed effect sizes ranging from r = 0.41 to r = 0.55 across C3, Cz and C4, which the article calls "medium or large".
"Children with ADHD exhibited higher TBR in each of the controlled locations in the midline, i.e.: C3, Cz, C4 (Hypothesis 1a). The obtained effects should be considered medium or large (r ∈ 〈0.41, 0.55〉)."
Discussion¶
Related Claims¶
- Sleep restriction lowers tonic arousal (raises EEG theta power) in a simulated classroom, with a medium effect — related
- Under normal conditions children with ADHD show deficits in vigilance, visual search and divided attention relative to TD children — related
- In a randomized three-arm trial, medication but not physical exercise or neurofeedback was related to improved response inhibition and reduced theta power in children with ADHD — related
