Notes: Values reported in the shaded cells are the zero-order Pearson correlation coefficients [95% confidence intervals] without any covariates whereas partial Pearson correlation coefficients with WISC-IV General Ability Index (GAI) as a covariate [and 95% confidence intervals] are reported in the white cells; ADHD = attention-deficit/hyperactivity disorder; Control = typically developing controls; AUC = Area Under the Curve (more AUC = less discounting); MotivationΔCom = standard go/no-go commission error rate – motivational go/no-go commission error rate (more positive number indicates greater reduction in commission errors with motivational contingencies); CogLoadΔCom = complex go/no-go commission error rate – standard go/no-go commission error rate (more positive number indicates greater increase in commission errors with greater cognitive load).
