Hearing lips and seeing voices: The science of the McGurk Effect

Spoken language is all about sound, right? Maybe not! Our brains make use of every bit of information available to figure out what we’re experiencing, but this process can cause us to experience some trippy illusions. Let’s explore the McGurk effect - the visual/auditory illusion where what you see rewrites what you hear! If you're interested in perception, check out the Perception Census project!
