Search for Optimal Presentation Timing in the Method of Maintaining Arousal Level by Inducing Intrinsic Motivation

Abstract

In our previous studies, it was suggested that inducing intrinsic motivation for driving behavior is effective in maintaining arousal level. In the present study, aiming for further optimization of this method, we examine the influence that timing of inducing intrinsic motivation gives to maintaining arousal level. Different timing of inducing intrinsic motivation depending on the arousal level was tested, and the arousal maintenance effect was evaluated. From experimental results, it was suggested that it is appropriate to induce intrinsic motivation at the timing of 60% sleepiness level at the latest to increase the arousal level most effectively.
