The McGurk effect

Close your eyes, play this movie, and listen. Open your eyes, replay and listen again. Is he saying "ba ba" or "da da"? It's called the McGurk effect. The man in this video, and its creator, is Arnt Maasø, associate professor at the University of Oslo.

I uploaded this a long time ago after grabbing it from an antediluvian webpage Arnt had on his university's site. I let him know that I had put it on this thing called YouTube and volunteered to remove it (since it's his); he actually responded very nicely and said, "the more, the merrier." Thanks Arnt!

Please read the comments for this video for details on its original creator and how to contact him. He's a college professor who granted me permission to upload it, so I doubt he'll give you any grief.
