要約(英語): A mastication sound is one of the important factors in the perception of taste. Effects of the mastication sound on texture, pleasure, and discomfort have been investigated by sensory evaluation based on psychological questionnaires and texture evaluations. However, few quantitative evaluations of effects of mastication sound on human cognitive processes have been conducted. In this study, we evaluated statistically and quantitatively the physiological, psychological, and behavioral parameters measured by the oddball task using each of three types of mastication sounds as target stimuli. As a result, significant differences were found between preference and latency of P300 depending on the type of sound, suggesting that latency of P300 is an index that reflects preference. In the correlation analysis, a negative correlation was found between ease of audibility and latency of P300 and reaction time. Therefore, it is suggested that event-related potentials are an effective index that can evaluate the cognitive characteristics of mastication sound.
