Description

Effects of playing video games (Grand Theft Auto III) on the psychological conditions of the players using chaos analysis of pulse waves and their subjective feelings were investigated. Participants in the study were university students (n=19). Efectiveness of the relative values of the Lyapunov exponents was examined as an index of the psychological condition of the players. The number of crashes with other cars and people were measured as indices of play. Relative values of Lyapunov exponents were identified using chaos analysis of pulse waves. Furthermore, subjective feelings were measured using questionnaires. The results indicated that the group with the lower relative values of the Lyapunov exponents during playing compared to before playing had more crashes with other cars and people. Furthermore, it was indicated that the players enjoyed the game and were relaxed. It is suggested that the relative values of Lyapunov exponents can be an effective index of the psychological condition of video game players.
