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 Dyslexia is associated with a significantly higher inhibition z-mean error composite score than controls (Cohen's d = 1.01). → Doyle C 2018 q3 i? The inhibition z-mean error composite difference remains significant after controlling for processing speed (no effect size printed for the controlled analysis). → Doyle C 2018 (2)

Evidence

Doyle C 2018

Doyle C, Smeaton AF, Roche RAP and Boran L (2018) Inhibition and Updating, but Not Switching, Predict Developmental Dyslexia and Individual Variation in Reading Ability. Front. Psychol. 9:795. https://doi.org/10.3389/fpsyg.2018.00795

q3 · i3 · associational · r2

Case-control ANOVA comparing 27 children with dyslexia and 29 controls aged 10-12 on inhibition z-mean error composites. The dyslexia group showed "a significantly higher inhibition z-mean error score than control participants" with Cohen's d = 1.01.

"At the composite level, dyslexia is characterized by a significantly higher inhibition z-mean error score than control participants [F(1, 53) = 13.85, p = 0.000, Cohen's d = 1.01; Figure 1]."

q3 · i? · associational · r2

ANCOVA controlling for processing speed (coding task) in the same sample. The inhibition composite difference remained significant, F(1, 52) = 9.29, p = 0.004, as did Picture Go No-Go and SART commission error differences; no effect size is printed for this analysis.

"After controlling for individual variation in processing spe ed, significant differences in the inhibition z-mean error score [F(1, 52) = 9.29, p = 0.004], commission errors during the Picture Go No-Go task [F(1, 52) = 8.50, p = 0.005] and commission errors during the SART task [ F(1, 53) = 5.91, p = 0.019] remain."
