Results of the picture ratings for (A) pleasantness and (B) arousal for each of the 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=19; one control subject did not complete picture ratings due to keypad malfunction). For both (A) and (B), error bars represent standard error of the mean. Between-group comparisons are indicated by light, solid lines; within-group comparisons for CUD are indicated by heavy, solid lines; and within-group comparisons for HC are indicated by broken lines; * p<0.05; all comparisons shown directly pertain to our a priori hypotheses. Supplementary Table 1 presents all significant comparisons (including comparisons not displayed in Figure 3), as well as means and standard errors for both picture ratings.
