ADHD, ADHD group; CON, control group. R−, no financial reward; R+, financial reward. Diagnostic Group, main effect of diagnostic group; Reward, main effect of reward condition; Diagnostic Group × Reward, interaction effect of diagnostic group and reward condition. n, number of subjects; M, median; SD, standard deviation. SST, stop-signal task, n-back, n-back task, CPT, continuous performance task; MDRT, median reaction time in the “go”-trials (SST); SDRT, reaction time variability in the “go”-trials (SST); SSRT, stop-signal reaction time (SST); Hits, number of correct inhibitions (SST); OE, omission errors (SST); RT, reaction time for correctly identified targets in milliseconds (n-back); d′, performance accuracy (n-back); FP, false positives (CPT); MDRT, median reaction time for correctly identified targets in milliseconds (CPT); SDRT, standard deviation of reaction time for correctly identified targets in milliseconds (CPT); ST, sensitivity threshold in milliseconds (Time Discrimination); ERR, absolute value of the deviation between specified and produced time interval in milliseconds (Time Reproduction); AS, Accuracy Score (Time Reproduction); DUR, mean trial duration in seconds (Delay Aversion). F, F-value.*p
