Mean±SEM of subjects' performance on the DevMod according to COMT val158met genotype. In the absence of any drug, val/met carriers and val/val carriers had higher DevMod in comparison to met/met carriers (#p≤0.05 for both). D-Amphetamine (10 mg and 20 mg) decreased lapses in attention in the val/val carriers (N=22; ***p≤0.001 and *p≤0.05 respectively). D-Amphetamine (10 and 20 mg) also decreased lapses in attention for val/met carriers (N=49) *p≤0.05 and **p<.01 respectively). The drug did not change DevMod performance in the met/met carriers (N=28).
