Motor-dependent tasks that require writing or drawing operations
visual cancellation
For the 10/36 spatial recall, SDMT, TMT-A, TMT-B, and visual cancellation tasks, which require writing or drawing operations, we used Microsoft PowerPoint and the screen sharing function of Webex Meetings. PowerPoint ran on the examiner’s laptop PC and was projected onto the participant’s PC (ENVY × 360 13-ay1000 manufactured by HP) connected to a 23.8-inch touch monitor (P2418HT manufactured by Dell) using the screen sharing function of Webex Meetings. This touch monitor is equivalent to commonly available touch-panel displays and is not a special device. To practice the use of the touch monitor and stylus pen before the test started, we asked participants to write numbers and draw circles and lines. Participants wore gloves when malfunctions occurred because their palms touched the monitor. The participants did not operate any equipment other than holding the stylus pen and drawing. Additionally, none of the participants reported difficulty in operating the stylus pen.In the VTC task, the testing seat was presented on the monitor of the same size as the FTF testing paper, and the examiner checked the handwriting locus in real-time on the examiner's monitor. In the 10/36 spatial recall, since participants could not use the checkers for answering, we asked participants to draw circles on the monitor-projected checkerboard. In 10/36 spatial recall using VTC, there is no limit to the number of checkers that can be placed; therefore, filling the checkerboards would result in a perfect score. Therefore, we defined this score as the number of correct answers minus the number of incorrect answers.
