「味」の正体―味嗅覚統合への心理物理学からのアプローチ

抄録

One of the factors that affect the judgment whether signals received by receptors of different sensory modalities belong to the same event is synchrony perception among multiple types of sensory information. In this article, we introduce the simultaneity judgment (SJ) task in cross-modal combinations (especially olfactory-gustatory):(1) development of measurement system for SJ task using olfactory and gustatory stimuli, (2) SJ tasks for three cross-modal combinations (olfactory-visual, visual-gustatory, and olfactory-gustatory), and (3) SJ tasks for olfactory-gustatory combinations under match/mismatch conditions. Taste and odor are important components of flavor. The results of our studies suggested that there is a correlation among match/mismatch between taste and odor, oral referral, and temporal resolution of synchrony perception from the perspective of flavor perception.
