Notes on the McGurk Stimuli
The McGurk-MacDonald effect is an audiovisual illusion. Here are some audiovisual files that can be used to demonstrate the effect. McGurk stimuli consist of an auditory syllable and an incongruent visual syllable that produce the percept of a different syllable (e.g. auditory "ba" + visual "ga" perceived as "da"). Other incongruent stimuli (e.g. auditory "ga" + visual "ba") do not produce the effect. Here is an archive of some the stimuli used in our publications, referenced in Beauchamp:Publications. McGurk and Other Stimuli Archive Note that some of these files require a particular video CODEC, the VLC player, available from
