In experiments illustrating the McGurk effect, participants hear the sound “ba” while watching a video of a person saying “ga”. In (A) doing so, most people perceive “da,” which combines both the sound and sight cues. This occurs even when participants are aware that they are different. (B) (shows / what / the McGurk effect / that / is / our brains / can) mix up sight and sound cues. It shows that our senses work together.
