Interestingly enough, around the same time that Harry McGurk and John Macdonald discovered what is now known as the McGurk effect, another British researcher also stumbled upon this phenomenon. Barbara Dodd discovered a similar effect with audio-visual speech interpretation but instead it was with the visual cue of 'hole' and the audio cue of 'tough' which ultimately generated the audio perception of 'towel'. These discoveries in audio-visual speech perception ultimately changed the way scientists and researchers view the interaction of different senses in the brain.
