Note. Co_hit, good answer in authorized delay for coherent condition; Inco_hit, good answer in authorized delay for incoherent condition; Co_miss, error in authorized delay for coherent condition; Inco_miss, error in authorized delay for incoherent condition; RT_Co, mean reaction time (ms.) for coherent condition; RT Co/hit, mean reaction time (ms.) per hit for coherent condition; RT_Inco, mean reaction time (ms) for incoherent condition; RT Inco/hit, mean reaction (ms.) per hit for incoherent condition; : group corresponds to the Fisher test comparing youth with ADHD to youth without; : sex corresponds to the Fisher test comparing boys to girls and (G × S) corresponds to the Fisher measure observed for the interaction between the group and the sex.
; = 0.07; all s are two-tailed.
