ABSTRACT
While modeling hand-control movements, a corrective reaction time indicates how fast our brain can generate a movement order based on received visual information. The corrective reaction time was found to range from 190 to 290 milliseconds in the literature, but with no data on individual difference. This pilot study applies Drury's (1994) the intermittent illumination model and modifies his experimental designs to measure individual corrective reaction time. Four participants perfonncd computer-based circular tracking movements by using a tablet as an input device. While conducting movements, the screen cursor blinked to generate predetermined visual delays. Measured movement speeds with the corresponding delays were utilized to calculate the corrective reaction times. The result of corrective reaction time ranges from 193 to 919 milliseconds longer than the reasonable range. Suggestions are given to deal with the potential issues.
