The McGurk effect is a perceptual illusion that our brains fall victim to, quite often.

If you listen to this long enough, you won`t be able to tell the difference between a bagina and a vutthole.

The illusion didn`t happen for me; I heard all the sounds the same regardless of how the guy`s mouth moved. But then, my thinking processes generally don`t work in images.

crazy! it really does sound the same if you close your eyes... they must sound edit the voice to say BA all the time.

"But his lower lip slips into his upper teeth when he says VA, which it doesnt do for BA, so to me this is garbage. He is actually making two different sounds, right?"

They redubbed the sound so it`s identical. All you are ever hearing is the same "Ba" sound, with different video overlaid.

both movements pretty much make the sound `ba` its just that `fa` is very slightly different. it pushes a bit of air, but without that air, its just `ba`

watch the video again with your eyes closed through the whole thing. The sound of his Va`s and Ba`s will sound only like Ba`s. Then again it may be difficult because you have already watched it thinking they are different.

This is news? This effect is evident in the fact that people sometimes need to watch lips while people are speaking to better understand them

"I heard fa when he said fa"

The point is he never said "fa", he said "Ba" but made the facial expression for "Fa" so you heard "Fa".

i`m not sure this is a real effect or not. the beginning of the "fa" sound is an unvoiced sound, meaning the vocal chords are not used. in most circumstances, you can`t hear the unvoiced part because it`s too quiet, so we assume by the mouth movements that he is saying "fa" instead of "ba". so in actuality, we hear the exact same sound both times, but we contextualize it differently.

for example, say `macaroni and cheese`, and then take the `and` exactly as it is said in that phrase, and place "fre-" as in fred before it. now add bill afterwards. the sound remains the same but the context changes.

I hope not exclusively. This isn`t that complex.

I wasn`t watching it so I heard the same thing the entire time.

Makes no sense, his mouth is doing something different so the sounds have to be slightly different, even though he thinks he`s making the same noise.. or do I just not get it?

At first when he switched to the VAH mouth movement, I heard VAH like..once then I closed my eyes and heard BAH again...and after that I just heard BAH, even when looking at the VAH mouth movements...*shrugs* Maybe I was focusing too hard on trying to hear the right thing.

I`m still not sure if he was saying baa or vaa. Which was it? It doesn`t help that v and b actually sound a lot alike, like r and l, and c and k.

Interesting phenomenon, but did they have to play that guy saying "baa" so many time? No.

What I find surprising is that people believe that we dream and that people can hallucinate, but stubbornly refuse to believe that their own senses can lie to them.

I`m surprised that they used this sound pair, since there are others that demonstrate the effect better. Just like vision, auditory perception is full of illusions that screw with perception. We just don`t realize it as much.

this reminded me of the robot mouth that was posted here on iab a while back. All it did was "FAA VAA BAAHH ... BAHHH BAHHH VAA BAA"

Freaky! Try opening and closing your eyes while he`s doing the FAH part. You`ll here BAH when your eyes are closed, and FAH when they are open.
