Measurement of executive function through modified stroop test in virtual driving situation

초록

Objective: The purpose of this study is to modify the stroop test to suit the virtual reality driving simulation environment and develop it as a tool to measure the user's executive function. Background: With the advent of an ultra-aging society, cognitive impairment of the elderly with neurodegenerative diseases is increasing. Accordingly, new cognitive function measurement tools that reflect embodied cognitive theory are being actively studied. As such a tool, a virtual reality environment in which perception-cognition-action can be combined is being used. Method: This scenario was developed toproceed by dividing into three-stage tasks similar to the existing stroop test in virtual reality. However, we changed the color and text of the stroop test to the direction and color of the car's navigation. Results: Expert evaluation was conducted, and the originality and usability of the vr experiment were highly evaluated, and the complexity and user feedback of the experiment were evaluated low. Conclusion: Scenarios should be modified based on expert evaluation, user evaluation need to be conducted, and we will verify validity.
