Effect of facilitating positions on behavioral arousal / 日本温泉気候物理医学会雑誌

Effect of facilitating positions on behavioral arousal was studied in 10 right-handed male subjects. Vocal reaction times (RTs) were examined in the three positions: 1) neutral position (N), 2) facilitating position of the left arm (FA), and 3) facilitating position of the left leg (FL). Mean RTs across the subjects were 165.0msec in N, 153.1msec in FA and 152.2msec in FL. Compared to N, RTs were significantly faster in FA and FL. Facilitating positions induce behavioral arousal or alertness and thus result in the decrease of RTs The neurophysiological mechanisms concerning behavioral arousal caused by facilitating positions were briefly discussed.
