Shown are the ANCOVA results (corrected for age and sex) for the main effects. Group (ADHD and control), task (VCPT and ECPT), condition (Go and NoGo), hemisphere (left and right), and the interactions between the main effects. Sex and Age effects are also represented. Depicted are the P-values and the effect sizes as generalized eta square values (η²G) and the degrees of freedom (df).
