Measurements of motion stimuli, physiological and psychological effects on motion-sickness and ride-quality have been carried out by using ship-motion simulator. It is essential to take into account of the physiological and psychological effects for the analyses of motion-sickness and ride-quality. The meaning of human expressions are always emotional and sensual, so that it is very difficult to obtain quantitative measure of these effects. In the present paper, the authors propose a method for the analyes of results of psychological measurements. A mathematical model using the hierarchical fuzzy integral is developed and is applied to the analysis of results obtained by the Semantic Differential Method (SD-method), one of the psychological measurement methods. Since the physiological and psychological effects are neither independent nor additive, the fuzzy measures that correspond to the degree of contributions of each physiological and psychological effect give good quantitative measures for the evaluation of motion-sickness and ride-quality. The mathematical model developed in the present study may be applicable to the analyses of results obtained by other psychological measurements.
