Processing Levels of the McGurk Effect
Maria C. Grosch* and Ashley K. Ramsey
Dr. Terry Palmer, Faculty Mentor

Perception can be a "multimodal" process, with different senses contributing different information to the final percept. The McGurk effect is an example of how information from the auditory and visual senses combines to create a unique perception. For example, when the lip movements from the sound "Ga" are played simultaneously with the audio from the sound "Ba," participants often report perceiving the utterance "Da". The present study uses the McGurk effect to investigate whether conscious awareness of visual stimuli is required for audiovisual integration. Participants looked through a stereoscope at a monitor that displayed a video clip of either a McGurk effect or a single syllable to one eye while displaying a visually captivating stimulus to the other eye. Data was recorded on whether subjects reported perceiving a McGurk effect or only the presented auditory stimulus and on whether the visual McGurk stimulus was consciously perceived. Findings will be discussed.
