Self-reported pleasantness ratings (A) and objective choice behavior (total picture viewing selections) on an implicit choice task (B) for each of four picture types (pleasant, unpleasant, neutral, and cocaine) for individuals with cocaine use disorders (CUD; N=20), as compared to healthy comparison subjects (HC; N=20). For both (A) and (B), error bars represent standard error of the mean. * p<0.05. Results show that although CUD rated the pleasant pictures as more pleasant than the cocaine pictures (A), providing higher pleasantness ratings than the controls, the CUD's objective choice behavior did not show this effect (here controls chose to view the pleasant pictures more than the CUD, who also did not show enhanced pleasant picture over cocaine picture choice) (B).
