From: Placebo Intervention Enhances Reward Learning in Healthy Individuals
Descriptive statistics for accuracy (% correct, (A)) and reaction time (in s, (B)) for each condition and stimulus pair. Error bars show the standard error of the mean (SEM). Accuracy increases and reaction time decreases in both placebo conditions, but more strongly in the high-uncertainty condition. Accuracy and RT also depend on stimulus pair, reflecting their increasing degree of difficulty due to lower stimulus-reward contingencies. HU: high-uncertainty; LU: low-uncertainty placebo conditions
