Multisensory Congruency Strengthens Olfactory Training

A recent study in Chemical Senses found that when participants experienced congruent multisensory stimulation (e.g., taste + smell), their perception of “likeness” was enhanced. In contrast, incongruent cues weakened perception. Interestingly, gustatory co-stimulation exerted a stronger influence than visual pairing, suggesting that cross-modal taste–smell integration has particular power in shaping how we learn and interpret odors.
