Visual Recalibration of Auditory Speech Identification A McGurk Aftereffect

摘要: The kinds of aftereffects, indicative cross-modal recalibration, that are observed after exposure to spatially incongruent inputs from different sensory modalities have not been demonstrated so far for identity incongruence. We show audiovisual speech (producing the well-known McGurk effect) can recalibrate auditory identification. In Experiment 1, an ambiguous sound intermediate between /aba/ and /ada/ dubbed onto a video face articulating either or increased proportion responses, respectively, during subsequent identification trials. 2 same recalibration effect opposite one, fewer revealing selective adaptation, depending on whether congruent nonambiguous one was used exposure. separate forced-choice trials, bimodal stimulus pairs producing these contrasting effects were identically categorized, which makes role postperceptual factors in generation unlikely.
