Counterfactual Thinking and Decision-making in Parkinson's Disease

All participants were asked to complete the Counterfactual Inference Test - CIT (McNamara et al., 2003), a neuropsychological test that measures the ability to produce counterfactual-derived inferences. Moreover, the decision-making ability will be specifically tested through ad-hoc questionnaire (i.e., the Decision-Making Questionnaire). Finally, all participants will be screened with an extensive neuropsychological assessment, particularly on executive functioning.
