Change in error in intensity ratings for Study 1. Study 1a involved baseline, training and post-training on the same model with training consisting of corrective feedback. Study 1b was a randomized-control trial (RCT) whereby participants were randomly assigned to receive training, as in Study 1a or a control that involved baseline, training, and post-training on the same model with no feedback of any kind during training. Scores collapsed across ratings for “angry” and “happy facial configurations. Lower values indicate less error; a score of zero indicates no error relative to actual percent morph. Error bars indicate 95% confidence intervals. *** p < .001.
