Try The McGurk Effect! - Horizon: Is Seeing Believing? - BBC Two

[utimo1122]

ba ba ba ba ba ba ba ba ba ba ba ba

[adamboy7777]

Like if you have actually seen this one! :D

[tonbogo]

Am I the only one that this didn't work on

[deadsearolls]

He talks like the bird that wakes you up in the morning and wont shut up so you want to shoot it with a pellet gun

[CATcatCATwoof]

i really want blue candyfloss

[neverstopmotion]

so this means I could finnaly make a rated G movie with a whole bunch of cussing in it? (but not really ;)

[ExpensiveGun]

I wonder how well this would work with "Buck you."

[imtheAJ]

@ExpensiveGun hahahaa..

[MonsterfulDino]

the sound did change. the 2nd picture, he was biting his lip and saying va, but for the 1st one, he didn't bite his lip and his was saying ba

[44tannertanner]

@MonsterfulDino okay. read this very slowly. The McGurk effect describes how what you hear changes given different visual stimuli. The WHOLE POINT of this video is that they run the visual of him biting his lip while playing the audio of "ba ba ba." this causes you to hear "va va va." The McGurk Effect.

[44tannertanner]

@MonsterfulDino close your eyes and listen to the whole video. You will hear nothing but "ba ba ba"

[cultmiester]

@MonsterfulDino no it didn't change.

were you not listening to the woman telling you it didn't change?

play it again and look away when he bites his lip - he DOES say ba.

[CassiLovesBrighten]

yes, your mind has just been blown.

[kingshockey22]

that looks like delicious cotten candy

[rezkidnegroni]

What if it "Vba". I've done it! :P

[Psychelectric]

Interesting tidbit regarding this phenomena, according to current studies:

It seems that people with an autimsm spectrum disorder are relatively immune to this phenomena, as in the visual stimualtion of lip reading doesn't overide the aural stimualtion of sound perception. The hypothesis is that they don't attend well to facial cues and thus are able to focus on the sound more objectively. TRANSLATION: Autistics typically don't get fooled by the McGurk effect.

Just thought I'd share.

[Psychelectric]

This notion is currently being researched and isn't set in stone, though the preliminary data shows this to be the case. I found it quite interesting considering the nuerological differences between people with autism and the general population. There are many nuances that couldn't be covered in this YouTube blurb, but I thought that those interested in this phenomena might want to know.

[jojoclown777]

@Psychelectric Are you serious? This "notion" has been set in stone for 30+ years. It's replicated on a daily basis in classrooms and research. As for the "neurological differences" between people with autism and general pop, THAT hasn't been set in stone. You will not find even a SINGLE study that CONCLUSIVELY shows neuro differences between the groups.

[hiddenshadow1221]

even after the video, i hear ba ba ba, so annoying, ba ba ba

[CATcatCATwoof]

@hiddenshadow1221 hahahahahahaha!!!

[AsSaSsiNxPANDA]

the real question is Will It Blend?

[reggiejax]

thats awesome

[Iamisfp]

Ｉhear ba and va.

[drbackjack]

I heard Baa the whole time, I guess I'm broken.

[munke2]

@fortythreek that means your brain is stupid. not your fault /:

[brodiebalonie]

hes got a pretty mouth... and pretty mouths do pretty thangs. I want to buck his bace is what im saying. :)

[xxghx0xstxx]

Holy fuck. When you hear Faa close your eyes. BAA!!! This shit is fucking my mind.

[YEREdDUARTE]

hispanics haha awe are immune to this shit

[LuFFyStRuM]

That my explain why I randomly learned to turn my head away when I'm listening to something

[em0girl2]

I'm sorry, but the part where the guy is in random different places just had me laughing the whole time XD The concept is....interesting. I would have liked to hear a bit more other than having the concept simply explained to me...They had a bit of food for thought at the end, that we can't always trust simply what we hear and see, which I found more interesting. And the thing about how the conflict provides us with a coherent view. Is there an extension to this video??

[FortyThreeK]

bah*

[FortyThreeK]

i heard nah the whole time until they said that i shouldn't.

[IndestructableXX]

I heard bfah...I'm weird?

[n00b1356]

Bah bah bah

[piip4]

What? I didn't hear any difference...

[ItsOttis]

It's terrifying how many people can't grasp this simple concept. Did the comment section recently become exclusive to the mentally disabled or is the general population really this stupid?

[benmantis01]

Yeah I heard the change and thought the trick was going to be an ambient sound coming in...and I was wrong. Am I sick?

[CessnaAviator317]

It changed for me, do I win then?

[animefiend7]

Is it bad that I can hear the fah's and the bah's regardless of eyes open or closed? :(

[draakon27]

baa faa baa ... fail

[Allicana13]

@draakon27 Same here. XD

[AccoladeGFX]

....i'm not affected...

[gregdoolan]

It's obviously a faa-king demon

[CrossfireX2366]

mindfuck

[XeroMata]

it fake, i had my eyes closed the whole video and they are bah and vah XD

[WillyWobSk8in]

@XeroMata thats because your mind is picturing him saying either or... try again.

[MrBrokenRevolver]

@XeroMata No it's not.

[AntonSlizzardhands]

Boring

[dlapidus421]

this pissed me off. i heard "va" or "fah" because his mouth moves differently in each picture. on the left he uses his teeth to make the sound as opposed to the right. does anyone else notice this?

[psychedelicsquid242]

@dlapidus421 The point is that on a purely physical level, _exactly_ the same sound is being used, and the same sound-waves enter our ears, but by the time our brain is done making sense of it, that visual difference is enough to change how we perceive the sound - once again, it is _always_ the same sound being played, regardless of whether you're "hearing" it as va/fah or bah.

[iolair1973]

I'm adding my count to people it didn't work for ... heard ba every time

[reality102594]

wHAT sORCERY is this?



[D4rQW4v3]

oh my shit

[KnaveMurdok]

The only subconscious effect this is having on me is I swear I can smell his gross ass cotton candy breath.

[MrPostednotes]

I heard Ba

[emotionaL2533]

is it only me or i don't really hear "FAH" when he was doing the second one?

[alfieandjoshie]

Honey Badger Don't Care

[Altair122122332345]

Bullshit. I can hear a slight difference.

[fingolfinBS]

Freaky.

[Leadman1989]

If you close and open your eyes the effect is even more freaky!

[poodoo138]

What's up with the random shots of an amusement park?

[roobysoho]

duck duck duck duck

[TheExtinctDinosaur]

my "speech part of the brain" is an asshole.

[AAwesomePantss]

amazing!

[Braulioiscool]

he should brush his teeth



[owliekat]

cool

[theskater4life24]

i heard ba then va

[danxfer]

will my brain explode if I look at both the pictures at the same time?

[717jonpaul]

It sounded all the same. Waste my time.

[RH98]

I would imagine that this is the longest period of time a psychology professor has ever said "ba ba ba" for.

[hustlevilleent12]

thats wild

[woobiegirl808]

all of you say you hear fa, but close your eyes and listen.

[xMikey21]

i heard ba then fa

[medifix]

Illness is an Illusion,

[mrugod]

I hear Fa Fa Fa

[TypoChamp]

@mrugod

Me too.

[RoboRobbeh]

aoww jesusss christ, FENTOOOOOOOOONNNNNN

[MysticalFlyingMonkey]

Witchcraft...

[MysticalFlyingMonkey]

I heard Ba and then Fa on the second one...

[PaaRecordings1]

that is awesome

[dj7andrex]

I hear Fa Fa Fa in the second one

[kaiserpuppylove]

hypnotism growing bigger by the second

[pesusieni]

When the picture changes i hear also "vaa vaa vaa".

[yoojda]

ALIENS

[daggertom1]

2:15 - He's been studying that for 25 years?! Seriously?!

[Annoyingthing321]

...what the buck?

[Naruto73176]

@Annoyingthing321 use the word 'buck' in the test. now when they change the video, what do you hear?

[MrVeryMad]

Ba?



[Vinnyaya]

Tobias

[RimboBobo]

Now what's the name of the effect where you see a muted video and you can hear the sound in your head?

[b33p]

@RimboBobo ...the lipreading effect?

[vampyminx]

Interesting but you'd feel like a right twat doing that.

[ironman5881]

Vsauce Army passing by....don't mind us :)

[Schizofreneia]

Well, I hear "Pa"...

[redeyeman06]

bar bar bar... bar bar bar... SHUT THE FUCK UPPP!!

[stoner4010]

You just like looking at men's mouths

Do you even lift?

[TEHCYBERskilled]

sheep baa baa

[rash1233]

more like the mcderp effect

[MrDrShadow]

I did

[yongzixian]

who looked from left to right and heard... fa ba fa?

[RavennShuffles]

i want this as my ringtone.

[1978Prime]

I don't get it, sounds like bar all the time. Just looks like the sound in out of synch, but nothing more.

[ParadoxJuice]

I hear 'baa' every time. :/

[lorannn424]

It does not work for all. But majority yes.

[Suuusn]

It doesn't work at all!

I'm hearing BA no matter what he's doing with his mouth.

Maybe it's because my ears are better than my eyes? :D

[Willy1234525]

And second, you can't say "B" without touching your lips...

[LaatearsLaaraine]

@Willy1234525 The audio is ba, all the time, he is at no point saying fa. The fa clip is mouth movement, purposefully exaggerated so that we can definitively see that he is meant to be saying fa when there is, in fact no separate audio on it. Ba is the only sound. Fa exists only in our heads. You are placing too much emphasis on how much he is exaggerating his mouth movement and totally missing the point of the thing.

[Willy1234525]

Am I the only one seeing that when he says "Faa" he is actually almost biting his lip, but when saying "Baa" he does it normal?

[FeR453CA]

ba ba ba...

[blotchyquill]

If you open and close your eyes while the image is changed to the "fa fa fa", it turns into "ba fa ba fa ba fa."

[helmutvs]

There are dozens of us... DOZENS!

[brendaandchons]

Whats also pretty cool is if you look away and it says ba then you slowly start coming back to the screen theres a point where its va again.... its like where your eyes actually calculate whats happening

[skarpy24]

I hear Va and Ba. I don't get it?

[FKProds]

@skarpy24 they're all ba.

[skarpy24]

@FKProds As I said. I hear Va and Ba.

[JesterAzazel]

@skarpy24

That's the point.. He's actually saying BA every time but when you see his lips emulate VA you hear it instead of what he's actually saying.

Try closing your eyes and watching this.

[skarpy24]

@JesterAzazel I hear Va and Ba every time. Even with my eyes closed.

[DarkSmurf11]

Oh my gosh, I just wanted her to shut up and let me watch that guy's face.

[lucasterable]

Read the wikipedia article before being dicks.

[drepwcfucka]

this s my professor!!

[youisiaint]

sorry I have to call BS as well...when I close my eyes I hear Ba ba ba first, then mainly va with a ba, and fa thrown in.  Nice try.

[abisfun]

He's totally bilabial with the [ba] and labiodental with the [fa]. Who is he trying to kid?

[dhandeen]

The "McGurk Effect" is a function of what we're used to hearing--Cultural relativism. If we spoke another language that used Ba or Fa as fundamental phonemes, we would be much more astute and be able to tell the difference.

[PipPipBagina]

fa fa fa fa

[Nisara1990]

MY MIND.

[oscar1616]

Wtf? This does not work on me," Ba" with a B was the only thing i heard during the clip!

[jorgekluney]

The McGurk Effect is the amazing discovery that even terribly boring, trivial bits of scientific research have the effect of astonishing people. At first glance the difference between actually hearing "fah" or "bah" is fraught with indifference. But if you put "BBC" in the upper corner of a video and have some British accented lass explaining the vanilla effect people become blown away with the illusory importance of the research. Quite impressive.

[intrptr]

Every time he goes Ba Ba Ba, I smell sheep.

[intrptr]

BS... I had no trouble hearing or reading his lips to see and hear Ba and Fa from the beginning.

Ba is lips and Fa is teeth on bottom lip. This is disinfo for people with ADHD who don't even listen or look to hear a whole sentence from someone else. What? Huh? Could you repeat that?

[Maartenn100]

@intrptr this proves that the illusion worked. Because you say that you 'hear' Fa. That's the illusion. he only says 'Ba' in both cases.

[intrptr]

@Maartenn100 BS. Close your eyes for the whole video. They mess with the sound.  You don't know what you are hearing. There is voice over, birds, kids and ocean breakers in the background. Try it, Ba Ba Va. Ba Ah Ba. Ba Fa Ba. The illusion is the audio track. This guy has got us all hoodwinked. And they have a brit accent. Naw, Brits tryin to fool the world? Bah...

[lucasterable]

@intrptr

If "Ba Ba Va. Ba Ah Ba. Ba Fa Ba." is what you heard with your eyes closed, then you should visit a otorhinolaryngologist.

[intrptr]

@lucasterable LOL... can you spell that? Others here hear the same . Maybe its our "earware"

[djbanizza]

So is this synesthesia?

[Einheitskreis]

Seeing IS believing!

[synsei1]

Wow, I thought it wouldn't work on me because I felt I was bad at lips reading but I definitely sensed a difference when the image changed.

[bloodpacer10]

solution Close your eyes :D

[geoffphuket]

Yes, agree. But without the stimulation you'd need to have a disorder in that part part of the brain for the effect not to be heard.

[TheRussianGlory]

I heard ba the whole time...

[Gollum9522]

Try watching the video, then just listen, dont look at the screen

[bigfroggy124]

va? i thought it was fa

[fifafb]

It's Fenton not Benton, in case you were asking

[sircolinbison]

FEEEEEEEEEEEEEEEEEEEENTOOOOOOO­OOOOOON!



[plarkmoby]

Benton! Jesus Christ!

[minifumatom]

FENTON! JESUS CHRIST

[alwaysmaxi1]

@minifumatom I saw that but what does the guy screaming it and chasing those animals have to do with his video

[uzih]

Ba ba ba ba Barbara-ann

[Subparanon]

Not affected. I had an initial moment of confusion how he was making a 'ba' sound with his lip tucked up in a vvvv/fff shape but then realized it was dubbed. Never thought I heard fa/va though. That said, if I turn the audio off, I can imagine what noise he's making by looking at his lips.

[geoffphuket]

@Subparanon You missed the whole point! lol Watch the video again and this time do exactly as they tell you.

[Subparanon]

@geoffphuket Um no I didn't miss the point. I hear the actual sound not the implied one. The effect doesn't work on me in this video or any of the others I tried.

[geoffphuket]

@Subparanon Seriously - and I'm not being sarcastic, but if you're human it must work - unless you have a hearing, visual or neuralgic condition. The effect is a result of our brains' confusion caused by conflicting information. It's not influenced in any way by race, language or education. Try it on your friends.

[Subparanon]

@geoffphuket Oh it definitely works on my wife. Doesn't affect me at all. I hear the same thing eyes opened or closed. It doesn't work on some people, I'm just one of them. For instance people with ASD are less likely to experience the effect.

[Ryeran]

@geoffphuket It's entirely possible for people to experience a diminished McGurk effect. There's a study that involves stimulating a part of the brain near the ear, the 'superior temporal sulcus' that serves as a node where this information collects. Diminishing the activity in this part of the brain is observed to reduce the McGurk effect in subjects. (read in Discover magazine)

[sandalsnsocks4]

@Avengers91 lol i don't know if you're being sarcastic or not.

[john888darling]

@Avengers91

... that's what you're supposed to hear... because you're dumb.

[HESamine]

Fuck you, McGurk effect !

Stop messing with my brain !!!

[MrBobjeffbob]

i heard fbah

[JawsstompeR]

My hearing know no bound.

[only3wishes]

May explain FOX News.

[Lazoo23]

Did she laugh at 0:06? I see what you did there!!

[hefejeffrey]

Over 25 years of studying the McGurk Effect and all you have is one example? I would like to invite you to my next fa-ba-que. Bring some slaw and we'll discuss the mystery of you having funding for this study...

[grandmautube]

Holy crap!!! This is amazing! (buck-buck-buck!!!  funny snapaxcrew!)

[thehiddenplace]

I still heard sheep all the time. Is this because English is not my native language?
