Note. ACT, Auditory Consonant Trigrams test; CPT, Continuous Performance Task; omission, number of times the subject fails to respond when target was presented; commission, number of response in absence of target; Hit RT, overall reaction time; Hit RT Block, slope of change in RTs over the six time blocks; Hit SE Block, slope of change in RTs standard errors over the six time blocks; Hit RT ISI, slope of change in RTs over the three interstimulus intervals; Hit SE ISI, slope of change in RTs SE over the three ISI; : 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.
