Ramachandran - Ames room illusion explained

[TheKcsmithy]

very interesting thanks

[thecandylover723]

THIS SOUNDS LIKE OBAMA VOICED OVER.

[LazyNDaCrazyDayz]

Fake and gay.

[TheNerdAmigo]

@LazyNDaCrazyDayz FAKE?? are you really that stupid?!

[TiredKitty11]

whats with the random guy at the end??

[bulmeruk]

Christ, you faggots argue about anything.

[felagund23]

people forget that this only works with one eye, if you were to stand there yourself, it would ruin the illusion because of depth perception.

you would see that the room is not normal shaped.

youd have to clsoe one eye for it to work.

so even if tribal people that were not broguht up in houses with paralle walls,

they would be fooled if they saw this video, but not if they/we were standing there in person.

[BrighamHB]

@felagund23 I'm not sure where you're getting that information from, but it's not true. I've been to science centers myself that had Ames Rooms, the illusion works in person with both eyes open. Binocular depth perception won't compensate for the distortion of the room - the brain is still fooled by visual cues into seeing it as a regular rectangle when it isn't.

[korpel]

beer pong:P

[CumtasticClimax]

OOOHHH FUCCKK YEEAAAH!!! How bout i LICK YOUR ASS? Hows about i melt in your mouth and nut in your hand? Nut in your ASS you little bitchhhh!

[button4boy]

how can a video be THIS out of sync! its like 3 whole seconds!

[deliconker]

This is a grotesquely out of sync video.

[badboyjose1]

will it make boobs bigger too

[generalbagsik]

Will it make my dick larger too? ;O

[MrEoinphelan]

it will be good for a porn movie just stand in the part were it makes you bigger

wow look it 15 inch

[potasiu2]

Will it blend? THAT is the question!

[monsta123x]

freaking out of sync piece of shit video

[XxTheCraziesxX]

rrrrrrrrrrrrrrrrresolve

[marinos1977]

@stazzou LOL what's your problem? LOL Where u offended by that? Freak LOL

[langzeekoei]

Goes to show how stuffed up we are. Technology as well as civilization has messed up our instictive minds.

[marinos1977]

It would've been better if they were naked. Huge tits and pussy. Small cock.

[stazzou]

@marinos1977 : damn... do a favor to the world dude, kill yourself.

[spagerbot]

@stazzou Thank you for saying that. He really does need to die.

[ztbsk8er]

lol, I'm doing psychology homework right now and I saw this illusion in my book and had to fin it on youtube!

[xenafan970]

Audio cuts out at 1:13.

[bentotheclarke]

headfuck

[oiramapap]

The automatic subtitles for this are just splendid. "in the real world obviously people don't change things going to loans - if you're willing to say that because the assumption that carl walz was much stronger"

[enroserie]

@oiramapap 

[pietzeekoe]

Rrrrrrrrrrrrrrrrrrrrrrrr

[mcpencil]

that is one huge woman.

[haszpla]

INCEPTION

[SAMARIdude]

WOAH. mindfuck.

[BLACKIESBOY]

DDDDDD: LITTLE PEOPLE GROW INTO BIG PEOPLE? NOT IN MY REALITY!

[Wiggyify]

the ball remained the same size :)

[SavethexQueen]

@Wiggyify it's all in the tile pattern :)

[thehobbit95]

@Wiggyify Nah it changed size a tiny bit :P

[MrBigYum]

The other thing is if you want to sell that room illusion, both subjects must turn slightly toward their left and look straight ahead as if they are looking at each other along a parallel line of sight. Then, if you use the ball you still have to maintain the posture that suggests the ball is coming from your twelve o'clock position.

[MrBigYum]

For this illusion to maintain itself properly, there can be no transfer between the two parties. The ball is a transitioning object that destroys the proximal bearing perceived by the eye.

[tjbayliss]

Great video if it wasn't MILES out of sync...

[BrotherTree1]

lol when she rolled that ball at 1:08...it gives the illusion away SOO BADLY.

[Mozzinator38]

badass

[marinos1977]

Rrrrrrrrrrresolve. Trrrrrrrrrrick. Rrrrrrrrroom.

lol

[kris242]

So if we were born into thinking that walls did not look parallel or not even knowing what a room looks like at all then the room would appear different to our eyes than it does now?

[sonicmaster5]

all tis is making me hungury

[BrotherTree1]

scientifically not explained well enough. zero marks out of three for your explanation for how the room creates the illusion.

[Jasexxxxx]

For some reason I can't see this illusion? I mean, I can see that the person on one side appears bigger, but when I look at the room, I can see that it's changed, altered, or structured in a way that the person being bigger makes sense?

Hm...

[totoymola]

must be better when the guy in the bigger image will show his dick and the smaller gril will freak out ... hahaha

[duplenty]

Another change to the youTube interface to the worse? Man, this place used to rock. They completely destroyed it. Thanks a lot, Google.

[QuoGirl]

yes, this reminds me of that scene in Willy Wonka where the room got smaller and smaller... This really helped explain that illusion.

[lilCtren]

looks like stairs

[deadlybug]

the woman is an awful tosser.

[VBunin]

обязательно такую себе сделаю:))

[bakustic]

[Llarky]

I imagine it's safe to assume that the windows contributed as well.

[sensationface]

OMG THAT BITCH! THAT IS NOT SPECIAL EFFECTS! ITS VISUAL EFFECTS! BUG DIFFERENCE...just sayin..

[clorofilazul]

Yes, he is on TEDtalks

[flenbo]

hey wasn't this guy also on TEDtalks?? he's great

[spiritro06]

wtf kind of accent is this? mixed to the max lol

[Robotnik777]

He's from India. Why do you think he accent is a laughing matter?

[spiritro06]

sounds like american english and some of his words have accents still, thats why i think its funny

[determinist48]

This is the same principle behind all religions.

[morbeck]

lol so true

[iamvegeta2008]

hehe...yup, thats true!

[LE0BRAND0]

loser

[sinnertuga]

let me post something dumb and humorous so you can feel good about me not being smart as you. dumbass

[manbot47]

If you're smart enough you use the word deduce instead of deduct.

[southbankthug]

...actually if you haven't ever seen this, it is hard to make such an assumption. just like Ram says, its how we know all rooms to be so our brain makes an assumption about it.

[SB20330]

"a grotesquely deformed trapezoidal room"

[BrotherTree1]

@SB20330 lol the guys an idiot. its not grotesque, its a perfectly normal trapezoidal room. it only looks grotesque because of the way the peephole is situated and designed in which we look through it. its where it limits our binocular depth perception and monocular linear perspective. along with the distortion of the sizes of the objects like the window and the clock, shape constancy of the room is maintained while size constancy is sacrificed. lol sorry i just to geek out there :P

[MiniCoopers09]

So, its tilted yet we think its straight?

[Totalidiocy]

So, let me get this straight.

In the frame at 0:30, you can see that the left side of the room is far bigger than the mind. So, when I look at this room from a peephole, my mind just pretends it never saw that in a "Your feeble human mind cannot comprehend the truth and is adjusting it to a form it can handle" sort a way, and my mind mentally makes the left side of the room small enough to match the right side. Is that it?

[PWNBEEF]

[LadyEnchantra]

I've been to the Ames Room and it's really cool!!!

I just came from Ontario Science Centre and luckily I found an Ames Room, There's a TV screen infront of you so you'll see this trick! This is so awesome you should go check it out guys!

[ThantosProduction]

WELCOME TO MIND FUCK

[kinosion]

fucking lier brain

[checkzitout]

lol!

bash it up!

[lostinaspoonofpeas]

if u watch this over and over will ur brain start to see it normally?

[BrotherTree1]

@lostinaspoonofpeas ahh my friend that is the beauty of an illusion. it always stays consistently strong as it was before, no matter how many times we see it. its always misinterpreted as it constantly differs from objective reality. its a distortion.

[chipdip9]

Wow what a tripp

[Jez32uk]

yeah this is the same as that errol and ricky , the room isn't long enough and the incline isn't gradual enough. plus they are walking diagonally when they should keep as close to the far wall as poss to 'sell' the illusion. The little girls in the brain story and the ordinary people in other videos are better at this than these so called professionals

[mattrmunson]

people who grow up in one of the few primitive tribes that still exist in the world do not make this assumption. It has been studied.

[TodaSyo]

You mean those tribal people don't have this illusion?

[Totalidiocy]

Yeah. People who live in places where rooms aren't built perfectly rectangular.

[delirium11]

@TodaSyo , the assumption of the parralel walls is not that strong there, i think.

[BillyAteMySoul]

@TodaSyo

I do remember a study of Aborigionies in Australia where they had a hard time seeing things in photographs- even pictures of mountians, because they didn't have practice with strongly foreshortened vision. I can see how if you weren't used to walls you'd see this illusion very differently.

[nitzeous]

@TodaSyo

They easily believe that a man can be 10 Ft high in 1 moment and 6Ft in another.

[TheNewCrankyWorkshop]

@nitzeous : They see right through the trick, because they don't automatically assume that the room is rectangular, because they haven't been brought up in a world of rectangular rooms and buildings as we have. That's what's going on.

[Mobixpl]

yeah state the obvious, no1 needs a study for that

[thedeeliciousplum]

@mattrmunson Please and that I thank you in advance, are you able to send me a link or the name of the tribe and/or of those who have studied this. i will look for this in the mean time. Yet, I wonder if there have been studies and hypotheses drawn as to why a more isolated community would lack this trait of perceptive assumption. Best wishes.

[momohead35]

I love the way he rrrrolls his "R's" when he speaks haaha. btw, what if there was a person who never knew anything about parallel walls? What if they never assumed all walls were parallel? Would this be on optical illusion for them?

[Britlurker]

Its built into your brain, you maybe can 'force' yourself to see the the room as it really is. But its not about assumptions, its about hard wiring of the brain.

[magicfreak123]

Look at the bottom of the back wall at 0:32.

Now draw a straight line (in your head or with your finger on your screen) from the bottom corner of the right wall to the bottom corner of the left wall. It's a perfect illusion if you don't know how it works!

[2ndOfficerCHL]

I love perspective tricks like that. Maybe I'm a nit-picker, but I think the left side of the room should be a little farther away...I can see the tipped floor and ceiling a bit.

[JuliusLjungberg]

Those are so cool.

[ThinAir715]

Woah....I thought it was just a special effect 0.o
