HacksZine is hosting a video by Brian Sawyer who riffs on the Mind Hacks book entry on the McGurk Effect and shows how this is used in movies.
The McGurk effect is, for example, where when you hear the sound of someone saying ‘Ba’ at the same time as you see them saying the sound ‘Ga’, you hear the second, because the information from your vision shapes how you perceive the sound.
Sawyer notes that this is commonly occurs in movies when they’re dubbed, so despite the character saying ‘You lousy melon farmer!’ when this was obviously not what was said in the original, the dubbing doesn’t seem completely out of whack.
