In order to assess psychophysiological state of the hyper arousal, pulse transit time during a mental task was analyzed using the ECG R-wave finger plethysmogram onset asynchrony (RPA) measurement. As the mental task, the authors used the Wisconsin card sorting test (WCST). In the test, the following two kinds of condition were used: (1) a toy balloon burst setting with time limit, and (2) a narrated Japanese novel comprehension test. Under experimental conditions, measured RPAs were shorter than these in control conditions. It is suggested that the RPA is a possible tool for the assessment of hyper arousal through the autonomic responses.
