Visual-Olfactory Interactions: Bimodal Facilitation and Impact on the Subjective Experience.

摘要: Odors are inherently ambiguous and therefore susceptible to redundant sensory as well context information. The identification of an odor object relies largely on visual input. Thus far, it is unclear whether olfactory stimuli indeed integrated at early perceptual stage which role the congruence between inputs plays. Previous studies visual-olfactory interaction used either congruent or incongruent information, leaving open nuances shape perception differently. We aimed answer 1) information stages processing, 2) a gradual dichotomous phenomenon, 3) influences bimodal stimulus evaluation identity. found response time speedup that consistent with parallel processing according race models. Subjectively, pleasantness increased increasing congruence, orange images biased composition toward orange. Visual-olfactory was perceived in distinct categories, notion phenomenon. Together, data provide evidence for facilitation stimuli, interactions influence various levels subjective experience.
