Optical illusions are images that seem to trick our minds into seeing something different from what they actually are. But how do they work? Nathan S. Jacobs walks us through a few common optical illusions and explains what these tricks of the eye can tell us about how our brains assemble visual information into the 3D world we see around us.
Lesson by Nathan S. Jacobs, animation by TED-Ed.
I don't know but upside-down Abe is creeping me out
lol ikr
XD WAT HAPPEN TO UR EYES LINKY!?!?
thatannoyinguy 25 lol rapmon pic
I lost my mind looking at that one
why didn't he do that on Trump?
I get why the illusions work the first time, but why doesn't the brain adjust it once it realizes that it's assumptions are false? :(
Eden Kaufman because that's how the brain works. You're not being tricked by the environment, you're being tricked by your own cognitive process, the brain simply can't change the way it works with this kind of new information, because doing that would also change how you see 3D images. This illusions have place because the brain is always assuming we're watching tridimensional objects. You're brain isn't going to change itself for you to watch different something it doesn't even affects you. You see the concave for the lightening, and even if you know that's true, you can still perceive the lightning and will keep understanding the universe as it behaves outside laboratory testes like this one's.
Eden Kaufman besides, the definition of am illusion is precisely that you can't stop perceiving it that way no matter which amount of new information.
didnt u hear what he said? ur brain tries to be as efficient as it can be, so it figures out that there is no need to keep them
Underated comment
Although that is true your eyes are just sending you raw data your brain interprets it and sometimes your brain interprets it as fake. Now is it a trick of the brain if the brain knows it an optical illusion.
i learn more from ted-ed than in school
same
It’s weird that that is true but we learn different rhings
Dang bro just roasted the whole educational system
Nice but then you would have to score an A+ in UA-cam
FRRRRR
4:09 Oh my God that's creepy, especially with the shadow on the eyes
TheGAMING Channel
This is a great explanation that breaks down exactly how our eyes are led to see optical illusions!
This was very well explained thanks, Im always seeing optical illusions but never completely understood how they happened
착시현상이 우리들의 두뇌를 속이는 방법에 대하여 배워보는 시간이 되었습니다. 보는 눈의 시점으로 착시현상을 이해해보는 시간이 되었습니다. 정말 재미있는 시간이 되었습나다. 감사합니다.
My brain is gonna be so pissed at me for watching like 50 of these in like an hour.
I can't believe I didn't notice that lincoln illusion when it was first shown upside down. Pretty cool stuff.
4:00
Me when the water starts rising after squatting at the local taco bell
😐
That upside down Lincoln creeped me out once it was the right side up :-/ Gonna haunt me in my sleep!
What software do you use to make these videos? :O
We mostly used Adobe After Effects for compositing, and Dragonframe for stop-motion animation.
TED-Ed Thx, I might use some tricks for some artwortks ^^ as i know a bit now how the brain work
Darshan
Yes jeeranan?
if you change it into the colors used in graphs for math (green lines and white bg), could it have no effect on us?
i think no.
my marks still gonna be constant and 0
The narrator has got to be the best narrator I know, (well, 2nd to Morgan Freeman XD) He always makes the video soothing to hear and very clear. Kudos to the Narrator! ^^ (who ever he is)
He's Addison Anderson
Mind Blown
I still don't understand the explanation about lateral inhibition
Lateral inhibition increases contrast, meaning when a light and a dark thing are near each other, the light thing appears lighter and the dark thing appears darker. The illusion in the video works because the intersections of the grid have less black near them than any other point on the lines, and the relative lack of contrast between the intersections and the background causes the intersections to appear darker than they are. I don't know why this is only noticeable in peripheral vision, maybe you can look that up if you're interested.
Alabaster I guess that is because of the receptors that pick up black and white (or rather light and dark) and the lack of them in the middle of your retina.
When the Abe photo was upside down it looked creepy at first then I noticed what was up when it turned around.. it looks weird both ways tbh.
Yeah, the same.
The abe one didn't trick me
The white point is surrounded by more white on all four sides than any white point along a line segment.
Does the language make sense? Does he refer to a Hermann grid where there is no highlighting of the intersections?
I think there is an error in the text or the name of the grid. Wikipedia distinguishes between Hermann Grid illusion and the scintillating illusion. Wikipedia also shows that some researchers have contended (doubted) that the lateral inhibition actually can be used as an explanation - but then again, references are missing.
Great video! Awesome animation too :)
Very interesting(as usual). Good work
🧀🧀🧀🧀🧀
The muffin pan looks normal to me. Just the one looks like a flashlight is focused perfectly on one spot.
Awesome channel!
I agree
Excellent explanation :)
the pan is not defective the cup has inverted shadow
4:00 this gave me nightmares for 2 weeks
you should make a creepypasta about it XD lol
I have that same plastic eye model at 1:48. The quality is absolutely terrible.
The Abe Lincoln didn't work on me...
mlg
Yup. I thought it was a Dracula version of him. Till now I don't understand what the narrator meant
+ROBIE
Could it be related to autism in some way?
You know, he said about how we focus on the mouth and eyes for knowing the emotions of the people you are seeing.
Nameless Name wow.
+Nameless Name No. I have autism and it kinda worked on me. Also that was harsh.
Yeah those upside down faces never work on me. I can instantly tell the eyes and mouth are flipped.
i saw the muffin pan and when u said the one facing the other way popped up i was like what arent they all flat?
also i found the second picture suspicious instantaneously
I don't understand very much what is lateral inhibition. Could you explain me, please?
I love watching these
That Lincoln face is unsettling.
The 3D glasses in the top right are backwards. Idk if the colors are in the right place but left and right are in the wrong place.
they are the old school cardboard 3d glasses folded up. red for right eye and blue for left...
For some reason i wasn't tricked by the muffin pan illusion.
Me either
Damn you evolution! :P
Thanks
Who do u get these optical illusions from
great video 4:10 brain shortcut is to focus only eyes & mouth to picture FACE
No way, that’s so cool!
The Lincoln illusion didn't work for me. The manipulated photo looked just as busted upside-down as it did rightside-up. A better illustration of finding faces in nothing would have been pictures of car bumpers, knots in bark or wherever faces coincidentally appear.
1:50
I have the same eye model on my desk. Go figure.
this is so cool
you are too good...
I forgot to breathe during this video 😂
The grid illusion works with other things too. If you stare at a woman's breasts long enough, your peripheral vision will not see her hand coming to slap you in the head.
Wait
I didn't see grey flashes in the grid, does that mean my eyes are defective?
I have that same eye model
please put how do we know how we feel
I have a weird reflex when I clean my right ear I want to cough I know it's got nothing to do with the video but just saying
You you hatt gandu
Abe Lincoln looks so creepy!
on the first one it stayd gray for a few sec.
im sorry... but i could tell abe's face was totally fucked up as soon as i saw it. lol
me too
Very helpful thanks😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊
damn! that grid makes my head swim. If i look for even a moment, i get all dizzy and the lines pulse and the intersections flash grey, black, and white. Thats not what the video said was supposed to happen. Am I broken?
The muffin pan illusion doesn't work as well as the grid(for me personally atleast) since I expect a shadow of the dome on the pan
i watch brain games so my perefreal vision is trained for this :) bring it on.
Well my brain is really stubborn.
Though it now knows the reason it still showing that muffin mould upside down and the grid something like blinking
Literally closed the video the moment they inverted Abe
I wonder what would happen if you raised a child from birth with real optical illusions and separated them from others then sat them down to look at these images. What would they see?
Upside down Abraham Lincoln will forever haunt me
Man, Lincons gonna give me nightmares
I think I've watched too much of these vids cuz my head hurts...
:I
Ikr? These stupid things are addicting. :O
You know I could not complete the video because that grid kinda bothered me
I wasn't fooled by the Abraham Lincoln, and I don't get how the muffin pan has a dome not dip…. I love the grid one too!
me to
Whoa some of these are trickey
When u fall to Sharingan Genjutsu..
Am I the only one that recognized the weirdness of the upside-down Lincoln from the start lol?
Oh!Inside Out!I like this movie
...
they tell me about the eyes and how did i not notice. that but berd
I am immune to any illusions
Why do I see a grey cloud looking vertex when I look into the sky that looks like a hole in the middle
The spots were brown.
4:01 this so scary lol
if u look at the upside-down Lincoln then focus on his eyes u will see something u will not be able to un-see and it will haunt u for your life
Every animation you do or Disney is optical illusion because they look like they are moving when they are not (Rip Disney paper animation 1937-2009)
memory bias of the mind
Instead of seeing gray in the first optical illusion I see red. Anyone else?
+Cango Mango Probably you are color blind
Now my brain hurts
wow
do a video about backwards messages
dan dis illusion is so real it work even it is post
4:09 I am officially closing this video.
The Abraham Lincoln one gave me nightmare!
the muffin pan and abe lincoln painting things at the start didnt work on me? weird
I don’t think the grid trick works if the white spots are a bit bigger
that upside down Abraham Lincoln... omg nightmaree
That's cool
Ted-ed its tricking my eyes it turns black when I change the spot
that fave upside down iss creeping me out to its creepy
How did the muffin pan illusion work?
IT CAN KILL YOU !!!!????
Is anyone freaked out by that upside-down abe face thing? It's just starting into your soul...
+Plant Zart look closer
good!!!!!!!!!
thanks, enjoyed this very much! It just shows to go ya', that our visual sense is a bit unreliable, in the Platonic sense that is :) we are easily fooled...we are chained in the cave viewing shadows of reality, not reality itself, . and what about the Parthenon?...how there is not a straight line in the entire building (to compensate for heaviness, etc) you can actually put a hat on the steps on one end, and you can't see it at the other end.... It's also interesting that our sense of hearing, the last sense to go when we die, is much more "rapid" in its translation & connection to the world, no upside_down screen that is reversed only in the brain, takes time to do all that, not so with hearing....& more than vision is the Greek "logos", reason, logic , sound.... speech, discussion, debate, communication.... interesting implications there, don't you think? that reality is largely invisible....
🤪🤪🤪
This looks like complete word mush, the ramblings of someone trying to seem smart
I will not be able to sleep tonight
I see black dots not grey
that abehr ham lincoln one scares me srry bout my spellling in in 3rd grade im 9
1:46 Is that the eye of cthulhu????
