Successful acquisition of discriminative conditioning. (A) Mean skin conductance responses during conditioning for CS+ and CS− in groups. Main effect of CS-type showing discriminative fear responses (CS+ > CS−) in all participants; (B) Mean subjective fear rating during conditioning for CS+ and CS− in groups. Main effect of CS-type showing discriminative fear responses (CS+ > CS−) in all participants, and a main effect of group showing greater fear ratings to both CSs in anxious youth relative to healthy comparisons (p = .004). Error bars represent the standard error of the mean. **p < .01.
