Abstract [en]

During multisensory experiences, visual stimuli typically override non-visual stimuli. Such “visual dominance” effects might stem from inhibition across sensory systems. Does visual dominance generalize to odor-visual pairings? We developed a binary categorization task (fruits vs flowers) with congruent and incongruent odor-picture pairings and a delayed auditory target probe that informed about categorization modality (olfactory vs visual). We investigated behavioral and cortical (ERP) responses.For congruent pairings, we found better accuracy for visual decisions. However, for incongruent pairings, we instead observed faster RTs for olfactory decisions. Incongruent olfactory stimuli thus interfere more with visual decisions than vice versa.Our ERP results from auditory targets on incongruent trials gave supporting evidence for olfactory dominance over visual perception; higher P300 amplitudes were more strongly correlated with faster RTs during visual categorization. A late “slow wave” ERP effect had later onset and longer latency during visual vs olfactory decisions. This indicates that in order to rapidly and successfully categorize visual stimuli (and ignore incongruent odors), participants need to allocate additional attentional and working memory resources. In sum, both behavioral and ERP effects suggest a higher level of interference from incongruent olfactory, compared to visual, input.These findings suggest that asymmetric inhibition across sensory systems is a fruitful way of studying perceptual dominance, and that olfactory stimuli can dominate visual perception, refuting the general notion of “visual dominance”.
