Abstract
Many qualitative and quantitative studies have been performed to determine emotional states in humans. Psychophysiological methods such as component analysis of electroencephalograms (EEGs), heart rate, blood pressure, galvanic skin reflex (GSR), and pupillary light reflex, have been used. However, few studies have addressed the psychophysiological evaluation of smell and taste, in particular, we know of no reports of the evaluation of tastiness. We carried out a study of the role played by odor compounds in mood states in humans in 1989 [1], evaluating the mood state quantitatively with a medical electronic instrument. In this study, we developed two basic methods of approach to the evaluation of tastiness. This first approach was to evaluate emotional changes produced by a refreshing drink, and the second was to evaluate the feeling in the mouth, depending on the temperature differences of drinks Pupillary light reflex and EEGs served as a physiological index, and the profile of mood state.
