Behavioral sensitivity to regret, expected value, and disappointment. Panels illustrate the logit model-predicted probability of choosing wheel 1 at varying levels of prospective regret (A), expected value (B), and disappointment (C), for high (red line)- and low (blue line)-psychopathy individuals. Shading around lines represent 95% CI for point estimates. Choice behavior in individuals higher on psychopathy were less affected by prospective regret (A) and disappointment (C) signals.
