Average reaction times (msecs) in patients and controls as a function of COMT genotype of responding to the cue to name the ink color of the word minus the average reaction times of responding to the ink colors of neutral symbols, divided by the reaction times of responding to the neutral symbols (6 word trials, 24 symbol trials). Error bars represent standard error. Post-hoc t-tests revealed no significant differences between COMT groups either within patients or within controls (all p's > .05).
