香りパルス一対比較によるベクションが香り知覚へ及ぼす影響の検討

抄録

In recent years, many researches on cross-modal sensory correspondence between smell and the other senses have been conducted. We focused on the relation between the sense of smell and that of motion. Vection, which is a visually induced illusion of self-motion, was used as a sense of motion, and effects of vection on scents were investigated. We measured the discrimination threshold of scents using a pair-wise comparison of two scent pulses under the condition of vection stimuli and two kinds of scents, and found that there were some conditions with significance difference. This result indicates that the sensitivity of smell may be affected by vection.
