Stress Response and Personality Traits based on Salivary Amylase Changes in Personality Rating
Emi Sato, Kouhei Matsuda

Abstract
The purpose of this experiment was to measure stress responses from changes in salivary amylase levels during the performance of a personality rating and examine their relevance to specific personality traits. The hypothesis of the experiment was 1) that amylase value would change before and after the act of personality self-rating and 2) that specific personality traits would change the level of amylase. The personality rating was divided into five conditions, and amylase level, which is a stress index, was measured before and after the rating. As a result of performing a hierarchical cluster analysis to examinethe changes in amylase level, the obtained clusters had three centers of gravity, and salivary amylase level, which was an index of the physiological stress response of the experimental participants, was divided into three characteristic clusters. As result of the GLM, each of the three clusters showed a relationship between certain stress response patterns and Extraversion. The personality factors that cause stress during personality rating were found to be related to Extroversion, Openness to experience, and Attitude score. The results of this experiment showed that stress responses differed depending on how individuals perceived tasks and performances that were not evaluated by others.
