Outline of Final Research Achievements |
In this study, we assigned the experiment collaborators a 30-minute calculation load similar in format to the Uchida-Kraepelin psychodiagnostic test. In Experiment 1 (measurement of objective stress response), we measured salivary α-amylase activity (sAMY) at one point before the calculation load and at eight points after the calculation load. In Experiment 2 (measurement of subjective stress response), we asked the subjects to rate their degree of stress before and after the calculation load, using a 5-point evaluation method. The results showed that the sAMY value recorded immediately after the loading was significantly higher than that before the loading.The degree of stress reported using the 5-point evaluation method also varied significantly between before and after the loading. We concluded that the calculation tasks used in the present study significantly increased subjective and objective stress responses.
