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
@@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.
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?
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.
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.
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.
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.
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.
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!
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)
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."
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.
@@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.
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.
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
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...
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.
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.
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 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?
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.
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).
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.
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.
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.
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.
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. :) :) :)
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".
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.)
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."
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...
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
Because you are probably accidentally focusing on the sound too much. You need to focus evenly like you would if you were having a conversation with the guy saying "Baa baa baa."
Corey Mckay like wheedler already said, the expert said it's IMPOSSIBLE to override it~ But I personally need to actively imagine to hear an f sound to make it sound like "Bfah" in my head, otherwise all I hear is "Bah"....
I am a native Portuguese speaker. The first time I hear "ba" a few times and "pa" most of the time. Already the second time I hear "ba" 100% of the time.
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.
Yes, right-- perception is cross-modal. I was going to do my master's thesis on the most interesting and potentially powerful cross-modal perception (aka, the oh so controversial "synesthesia" phenomenon) -- but the Prof. I wanted to work with got too tired of me parsing out all the inter-disciplinary implications, and he told me to go away. I think he was a little more concerned with getting his own papers published, about how the thickness of paint on a canvas is somehow interesting, and how the way an articulated lamp with built-in springs is worth studying. Academia doesn't care about what matters; it cares about what makes more academia.
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.
