The Colavita visual dominance effect refers to the phenomenon in which study participants respond more often to the visual component of an audiovisual stimulus, when presented with bimodal stimuli. Research has shown that vision is the most dominant sense for human beings who do not suffer from sensory difficulties (e.g. blindness, cataracts). Theorists have proposed that the Colavita visual dominance effect demonstrates a bias toward visual sensory information, because the presence of auditory stimuli is commonly neglected during audiovisual events.
