I crossed my eyes to merge the two images into one, and my brain bluescreened.
+Robert Miles XD
+Robert Miles McGurk exceptions are the toughest ones to handle... hahahaa :P
+Robert Miles LOL! Now THAT'S funny!
There's an app for that.
Are you trying to kill me?
I can't believe this works. I started hearing a British woman after a little while.
K F haha
Why is he eating white and gold cotton-candy?
😂😂
Especially all the time we’re supposed to be hearing fa.. can she just let him talk before interrupting?
LMAO
Not to be confused with the 'Politician Effect', where no matter how their lips move, bullshit comes out.
The Trump effect?
lol no, Trump doesn't speak "bullshit" he speaks "true shit", learn the difference ^^
Nekogami-Crystal Interesting assertion regarding a man who has had his public statements routinely proven to be false.
Nekogami-Crystal you talkin about the guy that drew around Alabama on a hurricane Dorian prediction map with a sharpie for no reason, said Covid-19 isn’t serious and’ll just pass like the flu and revoked military aid to ukraine because they didn’t want to investigate Biden?
HAHAHAHA FUNNY POLITICAL JOKE
Nah I still hear "Yanny"
blue dress
i hear laurel
😂😂
I hear blue shoe
Really, I hear green needle
hey Lawrence I know you are a respected professor at a university but would you mind us filiming you standing and saying Ba at various places on this beach
It's another illusion.
As he appears further away, your brain thinks the sound is quieter, as he is further away, when it is just the same 'ba'.
@@ParasocialCatgirl Yeah, but it doesn't work because that stupid bloody narrator won't shut the hell up.
@@RIPDavidBear I don't blame the narrator. I blame the idiot who thought it would be a good idea to play the narration at the same time as the audio illusion stuff when they were editing the video.
@@ParasocialCatgirl Actually, that's a good point, they should have played the close up of his face a couple more times while the narrator talks, then played the distance illusion.
@@ParasocialCatgirl I don't think that one's an illusion. I closed my eyes and it still got quieter as he moved back :/
I just now realized that I was experiencing the McGurk effect when watching Dr. Strangelove. I always heard "a pretty good weekend in Degas" and thought he messed up his line. The audio is 100% "weekend in Vegas" dubbed over him saying "weekend in Dallas". When I close my eyes he clearly says Vegas. I've watched that so many times and always heard "Degas". My mind is blown.
Yes, they dubbed over "Dallas" because of the JFK assassination.
1:10
My brain during an exam on the most difficult question...
“Ba ba ba ba ba ba”
*slides into Super Mario 64 painting*
How can we hear if our eyes aren't real?
That doesn't even make sense but ok.
It's Jaden Smith dude.
make him stop
BA BA BA
BA BA BA
Far Far Far
stop stop stop
You could just turn it off yourself.... 🤯
*ba ba ba*
All I heard was "pa" they got me thinking I'm retarded
Oof
XD
me too thooo
Great my neighbour's sheep heard me listening to this and now he can't stop Baaa'ing.
+SystemRichie My neighbor's sheep saw this clip and now they won't stop faa'ing :/
My neighbor heard me play this video and he's not even a sheep. Now he just sits there, looking at me and saying ba ba ba (or is it fa fa fa?). I think he's a mass murderer.
show it the vídeo. it can't faaa
I thought the first 20 seconds of the video was an ad 😡
Lmfao ikr?
Hahaha same here I couldn't figure out why it wouldn't let me skip...really cool demonstration of the effect though
Same I was waiting for the kip add link to appear ffs
Same!!!
Same! I was waiting for the skip button to appear
just imagine watching this video without the commentary.
bah
bah
bah bah
bah
bah
Black sheep have you any wool

First time watching this, almost eight years later.
This really is a remarkable thing. I've now watched it half a dozen times trying to convince my brain that I'm only hearing "ba" while still watching. It doesn't matter.
I can honestly say without hyperbole, that this is the single best example I've ever come across about not unconditionally trusting your senses.
In every clip I'm hearing the narrator
At the "fa fa fa" segment, I closed my eyes - it is "ba ba ba". Then I look again with eyes open, it is "fa fa fa", and you cannot help it. This is a very paradigm shifting thing to experience.
ba fa ba fba fba
I heard VA VA VA
I just hear PA PA PA only. The f doesn't work.
It's ba no pa idiot
Weird, I hear "pa pa pa" instead of "fa fa fa". Maybe it's because I speak Spanish? Until I read your comment I didn't even think about the "fa" sound.
Some have asked what is the purpose of showing the amusement park? The purpose is to show you that though you are looking at the man with the cotton candy your hearing and vision are each registering independently. You hear the carnival sounds, you see the man. No problem. Your brain knows to keep them separate. But in the ba ba ba, fa fa fa situation your brain allows your sight to tell your brain what to hear in spite of the fact that its not true.
It would be great if the narrator would shut up for a second!
Agree 👍
This is trippy as hell. If you look away while he's saying "fah" it will go back to sounding like "bah" again.
I was hearing "vah". Not "fah". Very interesting.
me too vah
and if you look at the way hes saying fah or vah and chose to think hes saying cah or bah by replacing your knowledge of what your seeing and chose to see it as something else i guess a easier way to describe it is lie to your self and say thats not a f mouth movement thats a C mouth movement if you chose to think this instead you will hear what ever you want this goes with everything in life really it requires concentration but some pick it up easily
a lot of compulsive liars actually believe their lies when they themselves created the lie its the same skill but being able to switch between the two at thought becomes a valuable one you can actually pass any lie detector test with this proably even a psychic (if they exist)
Not to me. I still discerned the subtle differences.
What I find fascinating is that our minds are designed to resolve the conflict to an end result (even if incorrect) rather than reject the information with some sort of alerting response, such as laughter or confusion.
Who's been sent here by Vsauce?
I was sent by a Vsauce video posted 5 hours ago. Can I borrow your time machine please?
Hahaha I was thinking the same thing.
you were sent here 3 years ago? This man has a time machine.
Dude let me use your time machine
can i use it please?
someone pls remix this
For some reason it was very satisfying to see the guy actually talk after only hearing him say BAH BAH BAH constantly.
Legend says that he can go anywhere he'd like at anytime, simply by saying the word "ba."
This is a fantastic experiment which highlights perception issues. There is so many things that occur every moment that we are not accurately encoding. Thank you so much for producing such a clear demonstration of sensory input and psychology. We want to use this for our consciousness workshop!
"I've been studying the McGurk effect for 25 years!"
:) life well spent
This comment should be in top
Yeah, you would've thought you could cover everything about the McGurk effect pretty comprehensively in maybe a week, tops! Especially when, after 25 years, the sum total of all that study seems to be "the visual bit of your brain overrides the audio bit of your brain and there's nothing you can do about it."
Figure he´s at a state/Gov sponsored tenure then
So what have you been studying for 25 years that is so much more worthwhile? How to make snarky comments in CZcams?
When you’re sitting here like, I hear “va va va”
Hmm, i never even considered fa. I assumed the effect was that it seemed like va, and I only checked the comments to see if people who also speak Spanish experience the effect less because b and v blend. I can't get it to sound like an f, only v sortof.
My brain: "pa pa pa"
I would like to hear/see other examples :)
Given how shit I'm at reading lips, the fact that this doesn't work on me in the slightest comes as a surprise to, literally, no one.
I read lips too, i heard fa fa fa AND ba ba ba.
This would have been for more enjoyable if the narrator actually stopped talking and let us listen and look for more than a brief second at a time.
I enjoyed It. Heard it completely. You must not have inherited the McGurk gene when you were born.
You poor thing. I'm sorry the narration confused you so severely that you were driven to write a comment about it.
@@dirtypure2023 It's not confusion, it's talking over someone, and I'll play the part of your mother today and teach you: It's considered rude and poor form to do so.
It's really surreal to watch this video when the effect doesn't work on you. It's like hearing a piece of music over a picture of a square, then hearing the same piece over a picture of a triangle, and being told that they're exactly the same like it's some big shock.
I don't know, but I always hear "ba ba ba"
Or it works better??
the same thing is going on with me i was very confused for a bit on what is supposed to happen because i just kept hearing "ba ba ba" over and over again
As the legend foretold. The chosen one has finally surfaced.
Praise me
Yeah I cant hear it either
I heard John Cena
Now I know why everybody mixes up Vatman with Batman. Thanks BBC!
If that damn lady would stop flapping her gums every few seconds maybe I could concentrate on what the guy was saying.
+carriersignal Careful dont mess with Harry Mcgurk! - Signing off as the McGurk clan
Did you know you can rewind videos?
this really doesnt require concentration lol. it's not that kind of illusion
He's saying "ba ba ba"
Thank you, Adult Swim, for letting me know this exists.
I believe this is why sometimes when you listen to a song, you can't recognize some of its lyrics.
Brilliant! This adds to Janet Werker's 1989 linguistic discovery of how we become native listeners after being born universal listeners (American Scientist, Becoming a Native Listener). Interpreters read lips in two languages, usually without realizing it.
I still heard Ba every time even when they were saying I was suppose to be hearing Fa. You're suppose to hear Fa because of the different mouth movements, it looks as though he's making an F sound even though it's actually still a B. So what does it mean if the Mc Gurk effect doesn't work?
I'm sorry but I can only hear the same sound all the time. Perhaps it is because I use to listen to the radio and do not realize. Perhaps it's because I was adviced, I don't know. It seems to be a plosive bilabial consonant, like a 'bah or even pah,' but it does not change. Phonetics? Sounds? Perhaps each person filters the information in different ways, according to their language, culture or the day he has.
I hear b for one & b̪ for the other
Nah
I always hear “Pa Pa Pa”
Ok
Holy poo! That's really interesting! After knowing, when I concentrated really hard on what I was hearing I was able to break the illusion for a repetition here and there (not back to back) but my brain would revert back to hearing fa (presumably as my focus involuntarily shifted more towards what I was seeing).
p.s. Many musicians and audio engineers instinctively close their eyes when concentrating on the audio. Singers sometimes do it too, while performing.
It's not just for effect - it really does help you to hear it better - and, as this demonstration shows us, it also avoids what you're seeing making you wrongly interpret what you're hearing.
it never ceases to amaze me that our minds lie to us to fill in the gaps, who knows what else.
Things don't actually have color, they just absorb light in different ways. If you experience the world without using light, there are no colors.
Even more amazing is how CZcams gets us to see a man when it’s really a sheep
When I see him make a fricative sound I hear VAH with a very short /v/ sound, because the sound /b/ is voiced. If they'd picked a voiceless plosive /p/, then I'd probably hear FAH.
Every time I feel sad about having wasted my life, I feel better by remembering this guy who spent 25 years studying an auditory illusion.
irony is... he probably earnt a lot of dosh out of it. 🤣🤣🤣
LMFAO HELP
This is pretty crazy. I closed my eyes and everything was "ba." Opened my eyes during the "fa" part and it was "fa." The sound is definitely "ba" but it changes depending on what I saw his lips doing. I've always tended to look at people's lips when they are talking to me, rather than in the eyes, and I think this must be why I do it -- it helps me understand what they are saying.
It's more useful to understand a person by syncing the sound to the sight rather than the other way around, because what is intended is likely what we see.
Since [v] is by definition a fricative and [b] a stop, there has to be distinction, if they are both pronounced according to their phonetic description.
One of the biggest reasons so many people struggled during the mask mandates is because a lot of us are using visual cues to get the whole message when someone speaks.
My daughter discovered she was 90% deaf and now wears hearing aids. She got by all her life lipreading without realising. When masks were worn she couldn't hear people speak...
This video is extremely confusing for someone like me who doesn’t seem to be susceptible to the effect. „Yes, obviously, I always hear ‚ba ba ba‘; why is she pointing that out and what am I supposed to hear?“, was I asking myself throughout the video. Who else doesn’t hear anything other than „ba ba ba“?
I didn't either. At first I was wondering what was this video about. I wondered how this guy could ouptut a /ba/ with a mouth shape which looked like it would produce a /va/ sound.
Reading comments, I realize most people 'lip read' and are 100% certain everyone does that. Well, I don't. I never lip read, and I only rely on what I hear.
This is why in nightclub I seem to be the only one to not be able to communicate. I always say "WHAT?!" and then I lean my head down and show my right hear so the person can directly shout to my hear. Yeah, that's me in nightclubs.
I also speak multiple languages and I do like phonetics study in general. In other words, I rely on my ears more than what this 'specialist' think.
I always noticed that some people look at your lips when you are talking. If you pay attention to where they look, some may instinctively look at your mouth when you speak. It always puzzled me. Now I guess they are just more visual people. At least this video here explains this phenomena for me.
My favourite bit was when he said "ba".
Mr. McGurk himself. Legend!
I heard fa twice but it corrected itself to ba.
Same here. First two are hard F's, last one's a B.
There was a clash, but it didn't change what I was hearing. It was just really weird seeing the mouth making shapes that weren't consistent with the sound. I'm super sensitive to picking out voice dubbing, but I never suspected I was a weirdo because of it haha
Yeah the sounds changed back and forth for me.
it’d be interesting to see if this works for non english speakers? for example in korean the difference between b(ㅂ) and f/p(ㅍ) is immediately recognizable by native speakers but is very different for non natives to distinguish, even when looking at mouth shape.
My brain kept waiting for... blacksheep.. and was rather disappointed at its non-arrival😅
If anyone calls this fake or anything, at the beginning when they say they are going to change it, look away, close your eyes, you'll still hear bah, right when you open your eyes and see his mouth, it's fah.
hi narrator. when you are doing an auditory illusion special, please don't talk over it. thanks. :)
Better, "hi editor, when the video is playing an auditory illusion, please don't play narration over it".
Both sounds are different and it's because when he says faa he does it while slowly bitting his lower lip.
I hear ba on the first one, and mostly ba on the second one, but on the second one there's this weird sensation I get (obviously true in this case) that happens pretty frequently of the audio and visals feeling jarringly separate.
I wonder if a different example would also work; say... "back off" :)
"back off" with a visual "f_ck off" would be interesting
This doesn't work on me. :/ But then again, the speech center of my brain is weak so I approach language differently than most people do, I think. That, or, taking speech therapy for nine years removes this "illusion".
I am a native speaker of English.
The native speaker thing doesn't really apply just to English, Western European languages are all affected. East Asian ones aren't as much.
I want a 10 hours version of him saying ba and fa
This is baakin' amazing!
I'm only hearing ba,ba, ba....
It did not work for me either. I heard Ba Ba Ba no matter how much I wanted to hear Fa Fa Fa.
I guess that means you have no future as a lip reader.
1973Washu
Um, "ba ba ba" is what you're supposed to hear in both instances. So you actually beat the trick.
kagi95 because I hear the right thing? ok^^
Did you try it with headphones on?
close your eyes and you hear ba ba all the time
I feel like this video is what Bad Lip Synch used to train.
I sometimes experence the illusion of hearing bits and peices of what a person is saying in a muted video if I am watching their mouth. I think this explains why that happens.
I always hear Ba
Then you have some sort of brain disorder.
THEclownxxx you mean brain enhancement? :D If you want to hear Ba I hear ba if I want to hear Fa I hear it.
Glampkoo disorder
Good for you.
You play Minecraft, so you already have a brain disorder.
Who else is here from Scott Adams' book?
Just read that part, though I've seen this video before. It got me last time, but I was kind of able to get my brain to not be fooled this time. It did sound like "fbah" a few times, though.
I think the amount our brains can be fooled is directly related to how much we're actively using them. Like his "moist robots" thing may be accurate when we let ourselves go on auto-pilot, but more a exerted focus helps us avoid it. (Or at least have a better chance of realizing it when it does happen.)
Present!
How does this experiment work with blind or deaf people?
Speech articulation and indeed listening in noisy environments isn't perfect especially when stress and white noise around, so it's adaptive: the sound we're trying to make is most important. However at the start of the video having established it was baa, and expecting a trick, I dissociated a little, I tried to step back and listen to hear the sound with my eyes open and could hear or flip between hearing baa and faa similar to seeing/flipping purely optical illusions, however it seemed to get less easy through the video, whereas an optical illusion doesn't get less easy to see both ways for me, except at each new introduction until I get it. That probably gets quicker although it feels tedious, trying to see what I have half a memory is there the way I saw it initially.
lol first I was hearing "pa" then when I noticed the changed in the picture I noticed his lips changed and I hear "fa". Just look at the damn lips!
He spent 25 years studying this?!
Yeah i mean. It couln't be used negatively right?
lmao ya what a loser
😂😂😂True xD
Nick Lee yep, and we watched for 3 minutes and basically know everything he does lmao
You live in the ignorance that you can learn everything someone who's spent 25 years studying a subject has in just three minutes. It must be a cosy life: "I can be a fighter pilot, I just watched someone fly one for a few minutes."
Imagine going to that beach and just seeing "BA BA BA"
Thanks Mr Fry interesting video!
Nice video. I followed a link from SciManDan and I hope (but don't believe, to be honest) that some flat-earthers did so, too.
It's really nice to see how well their "believe in your senses"-mantra works ;-) I guess most of them have never seen a stage magician eiher...
Am I the only one who hears “pa” not “ba”?
He's saying "Bye" in a Texan accent!
This is now my alarm clock.
I'm not sure I got it. I just kept hearing bah. The teeth thing didn't affect how I perceived the sound. I guess I'm McGurk-less.
I heard ba ba ba the whole time! WOohoo! I'm a freak! hahaha. But really, I think I've just trained my mind to hear sounds as they sound over the last 20 years. I learn music by ear and translate it to instruments. I compare audio gear and have been familiar with placebo type effects and have spent countless hours listening to avoid such a problem that I think I've actually trained my ear. The first time I watched this I hear ba the whole time. :) :) :)
As a pianist me too :))
dunno what I did to deserve this but.. I'm in the club too!
That's nuts ! Especially when you close and open your eyes randomly !
You can look away from the screen and whatever mouth movement you visualise in your mind is how it'll sound.
So nuts!
doesn't work on me. at all
Annoying Women keeps talking at the wrong time, interrupting the illusion
I know! I was so annoyed
One of most interesting things I’ve seen for a while!
Thanks for breaking my brain, SciManDan
Fa Fa Flack Sheep Have You Any Wool?
LMFAO
i heard ba no matter what
thanks vinny
I only heard "ba". The purported fa only was apparent when they explained that we were supposed to hear something else. But again, it only demonstrates that we are not all the same.
Let's turn this guy into a meme!! =D
this is why i have such a hard time understanding people when the wear masks
That is really interesting... cool :)
Reminds me of poorly filmed foreign films, usually from Hong Kong translated from spoken Cantonese into spoken English where the lips keep moving long after the actor finished talking.
This stuff is amazing. I love it!
