{"pk":29134,"title":"A Dynamic Neural Field Model of the McGurk Effect and IncongruousAudiovisual Speech Stimuli","subtitle":null,"abstract":"Our Dynamic Neural Field (DNF) model aims to simulate audiovisual integration in speech perception, including thewell-known McGurk effect (McGurk & MacDonald, 1976). The classic McGurk effect is characterized by a fusion ef-fect, whereby incongruent audio and visual stimuli are fused into a single percept, however other interesting audiovisualeffects are present in the extant literature. Our DNF model uses the same architecture and parameters across stimu-lus combinations to simulate a host of audiovisual illusory effects as well as audiovisually congruent, auditory-only,and visual-only controls. Our simulation results replicate rates of visual-dominant percepts, audiovisual fusion percepts,auditory-dominant percepts, and auditory dichotic fusion found in the extant literature, and illustrate how a complex patternof responses across different stimuli configurations can arise from common neural dynamics involved in binding informa-tion across sensory modalities. We are currently exploring how hemodynamic response predictions generated through ourneural simulations relate to real-time behavior.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Member Abstracts","is_remote":true,"remote_url":"https://escholarship.org/uc/item/47f3j1x1","frozenauthors":[{"first_name":"Ryan","middle_name":"","last_name":"Cannistraci","name_suffix":"","institution":"University of Tennessee","department":""},{"first_name":"Jessica","middle_name":"","last_name":"Hay","name_suffix":"","institution":"University of Tennessee","department":""},{"first_name":"Aaron","middle_name":"","last_name":"Buss","name_suffix":"","institution":"University of Tennessee","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2019-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/29134/galley/19005/download/"}]}
