The objective of this study is to objectively evaluate the subjective complexity by change in oxygenated hemoglobin and hemodynamics for the developing the relief method of stress based on improving preference by subjective complexity. The change in oxygenated hemoglobin concentration (ΔoxyHb) and hemodynamic parameters as physiological indices and psychological intensity as psychological indices were measured when performing the four auditory stimuli repeatedly. As a result, comfort and subjective complexity indicated the inverted “U” shape function. The tendency of the correlation between ΔoxyHb and subjective complexity was categorized into three main types. Significant differences of stress coping were found by hemodynamics. It was clarified that physiological responses to subjective complexity were assessable objectively.

A digital book has become popular along with the popularization of electronic medium. It is needed that assessment of not only subjective assessment about readability or usability, but also objective assessment of psychosomatic health impact. The objective of this study is an objective assessment of physiological and psychological effects of reading books using electronic or paper medium. This paper focused on hemodynamic parameters. The measurement item was VAS and POMS as a psychological index and hemodynamics parameters as a physiological index. As a result, low vigorous and unreadable were significantly recognized (p<0.05) in reading a book using an electronic medium comparing with a paper medium. Cardiovascular system became active coping because of sympathetic hyperactivity in the hemodynamic reaction. By contrast, using an electronic medium did not fit into stress coping. It was also found that parasympathetic nervous system enhanced with illegibility of the sentence and fatigue by usinig an electronic medium. For all of these results, it became identified a difference in a way to manage in physiologically with reading a book using an electronic and paper medium.
