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.
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.
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.
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)
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.
+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.
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.
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?
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
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.
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....
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?
Is it weird that i only see concave or convex on all of the circles in the muffin pan by just the way i think what i want to see? I cant see any any optical illusion in there. It is either all convex or all convave to me. 😂
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?
This is a great explanation that breaks down exactly how our eyes are led to see optical illusions!
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 RUclips
FRRRRR
4:09 Oh my God that's creepy, especially with the shadow on the eyes
TheGAMING Channel
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 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.
This was very well explained thanks, Im always seeing optical illusions but never completely understood how they happened
4:00
Me when the water starts rising after squatting at the local taco bell
😐
착시현상이 우리들의 두뇌를 속이는 방법에 대하여 배워보는 시간이 되었습니다. 보는 눈의 시점으로 착시현상을 이해해보는 시간이 되었습니다. 정말 재미있는 시간이 되었습나다. 감사합니다.
I can't believe I didn't notice that lincoln illusion when it was first shown upside down. Pretty cool stuff.
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?
My brain is gonna be so pissed at me for watching like 50 of these in like an hour.
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
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.

He's Addison Anderson

I have that same plastic eye model at 1:48. The quality is absolutely terrible.
Very interesting(as usual). Good work
🧀🧀🧀🧀🧀
That upside down Lincoln creeped me out once it was the right side up :-/ Gonna haunt me in my sleep!
Awesome channel!
I agree
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 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.
Excellent explanation :)
Yeah those upside down faces never work on me. I can instantly tell the eyes and mouth are flipped.
Mind Blown
The muffin pan looks normal to me. Just the one looks like a flashlight is focused perfectly on one spot.
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 don't understand very much what is lateral inhibition. Could you explain me, please?
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...
great video 4:10 brain shortcut is to focus only eyes & mouth to picture FACE
I love watching these
The optical illusion of a material universe Trap. One of the many reasons we are in this fix.
1:50
I have the same eye model on my desk. Go figure.
Who do u get these optical illusions from
For some reason i wasn't tricked by the muffin pan illusion.
Me either
I forgot to breathe during this video 😂
That Lincoln face is unsettling.
No way, that’s so cool!
Wait
I didn't see grey flashes in the grid, does that mean my eyes are defective?
please put how do we know how we feel
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.
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 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
on the first one it stayd gray for a few sec.
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?
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
Why do I see a grey cloud looking vertex when I look into the sky that looks like a hole in the middle
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 watch brain games so my perefreal vision is trained for this :) bring it on.
Am I the only one that recognized the weirdness of the upside-down Lincoln from the start lol?
You know I could not complete the video because that grid kinda bothered me
Very helpful thanks😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊
Damn you evolution! :P
Literally closed the video the moment they inverted Abe
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.
When u fall to Sharingan Genjutsu..
you are too good...
4:09 I am officially closing this video.
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
POV: ur watching this for a school art
I have that same eye model
I don’t think the grid trick works if the white spots are a bit bigger
Abe Lincoln looks so creepy!
im sorry... but i could tell abe's face was totally fucked up as soon as i saw it. lol
Man, Lincons gonna give me nightmares
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)

🤪🤪🤪
This looks like complete word mush, the ramblings of someone trying to seem smart
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!
Now my brain hurts
do a video about backwards messages
Thanks
1:46 Is that the eye of cthulhu????
this is so cool
Is anyone freaked out by that upside-down abe face thing? It's just starting into your soul...
+Plant Zart look closer
the muffin pan and abe lincoln painting things at the start didnt work on me? weird
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?
I will not be able to sleep tonight
Ted-ed its tricking my eyes it turns black when I change the spot
they tell me about the eyes and how did i not notice. that but berd
Oh!Inside Out!I like this movie
...
Instead of seeing gray in the first optical illusion I see red. Anyone else?
+Cango Mango Probably you are color blind
that abehr ham lincoln one scares me srry bout my spellling in in 3rd grade im 9
i dont get the muffin pan they all look the same to me right side up and upside down
Upside down Abraham Lincoln will forever haunt me
that upside down Abraham Lincoln... omg nightmaree
memory bias of the mind
I think I've watched too much of these vids cuz my head hurts...
:I
Ikr? These stupid things are addicting. :O
The spots were brown.
I am immune to any illusions
4:01 this so scary lol
the muffin pan works
I see black dots not grey
The Abraham Lincoln one gave me nightmare!
How did the muffin pan illusion work?
Is it weird that i only see concave or convex on all of the circles in the muffin pan by just the way i think what i want to see? I cant see any any optical illusion in there. It is either all convex or all convave to me. 😂
whats up with the joker cards
that fave upside down iss creeping me out to its creepy
Whoa some of these are trickey
dan dis illusion is so real it work even it is post
The muffin pan isnt an illusion, its just shading
