Abstract
To date, cognitive flexibility has been measured only using neuropsychological tasks, and has not been tested using more ecologically valid task due to methodological limitations. In this study, a virtual reality task was developed to evaluate cognitive flexibility in a real life situation and performance on this task was compared between 30 healthy individuals and 30 schizophrenia patients. Compared to healthy controls, a greater number of schizophrenia patients made concrete decisions, and their decision-making times were negatively correlated with the severity of their negative symptoms. These findings indicate that virtual reality can be an ecologically valid measurement of cognitive flexibility.
