Threat expectancy ratings to conditioned stimuli (CS+ and CS-) during run 1 and run 2 (collapsed across context) for each group (CC vs AA/AC). Greater responding to the CS during run 2 for the CC allele group was driven by increased responding to the CS+ in the CC allele carriers (p < 0.001) compared to the AA/AC allele carriers (p = 0.164).
