The McGurk Effect

Click here for a short video demonstrating the McGurk Effect. Here is the wikipedia entry for it:

The McGurk effect is a perceptual phenomenon which demonstrates an interaction between hearing and vision in speech perception.

It was first described in a paper by McGurk and McDonald (1976).
