Figure 2From: Incentive motivation in first-episode psychosis: A behavioural study The degree of reinforcement-related speeding in patients and controls. The mean degree of reinforcement-related speeding (as measured by the mean reaction time on 90% probability trials minus the mean reaction time on 10% probability trials) differs in patients and controls (t = 3.8, p = 0.001). Error bars represent standard errors of the mean.Back to article page
