Development of Measurement Tool for Execution Function through Behavioral Data in Virtual Bookshelves Environment: focused on the Shifting Ability

Abstract

Objective: This study aims to develop a measurement tool for the shifting ability as an Executive Functions (EF) in Virtual Environment (VE) based on the theory of embodied cognition. Background: Most of conventional EF measurement tools show an 18-20% difference between measured value through the questionnaires and ability of daily practices, which leads to dysfunctional problems in everyday life. Method: We designed a shifting measurement tool in VE. A measurement tool was developed by creating the scenario for organizing books on a bookshelf according to specific rules through an expert-based evaluation in a VE. (Color, Shape, Category) Using this measurement tool, we gained the tasks score data, duration, and the behavioral data of hand and head from 12 healthy adults(20-30s) and analyzed the data. Results: Using this Shifting measurement tool, we gain the behavioral data of hands and head, and tasks scores data from 12 participants. It is compared with the behavioral data of hand and head movement according to the task score. Conclusion: Findings of this study could be used to evaluate existing measurements and enhance a newly developed shifting measurement tool.
