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? No significant Group x Condition interaction on accuracy, and no binding-dependent ERP group differences, indicating binding processes seem intact in ADHD. → Ortega 2020

q3 · i? · causal · r2
Behavioral and ERP comparisons of Shape-Only vs Color-Shape conditions in the 18-vs-18 adolescent sample: "we did not find significant difference between groups regarding the binding condition", neither behaviorally nor electrophysiologically; no effect size is printed for the null interactions.
"In the current work we did not find significant difference between groups regarding the binding condition (Shape-Only Vs. Color-Shape), neither behaviorally nor electrophysiologically. Even though, the Color-Shape condition resulted in larger reaction times in all participants."
Discussion¶
Related Claims¶
- Adolescents with ADHD respond more slowly than non-ADHD peers across all conditions, and color-shape binding slows responses in both groups
- Adolescents with ADHD show poorer accuracy than non-ADHD peers on all conditions of a visual short-term memory task, with the largest drop on trials requiring WM updating — related
- Retrieval P3 discriminates Same from Different trials only in non-ADHD adolescents, indicating a failure of post-selection prioritization in ADHD — reports the opposite
- Encoding P3 amplitude is reduced in ADHD adolescents during visual WM encoding, in both early and late time windows — reports the opposite
