Age-related effects for the reward and punishment conditions separately. (a) Accuracy on the reversal, non-reversal reward and non-reversal punishment trials in the reward condition (y-axis) for the four different age-groups (x-axis). (b) Linear and quadratic trend between accuracy on reward-reversal trials and age (linear: F_(3,54) = 16.05, p < .001, quadratic: F_(3,54) = 9.73, p < .003). (c) Accuracy on the reversal, non-reversal reward and non-reversal punishment trials in the punishment condition (y-axis) for the four different age-groups (x-axis). (d) Quadratic trend between accuracy on punishment-reversal trials and age (F_(3,54) = 18.4, p < .001). Error-bars represent the standard error of the mean. Symbols represent individual data points. **Significant difference at p < .005, *Significant difference at p < .05.
