Visual illusions, from magic tricks to images that have sparked internet feuds, are providing scientists with evolving insight into the complex act of seeing. Illusions play with the way our eyes and our brains work together and help establish that what we “see” is shaped by everything from light and eye movement to the influence of expectation, memory and desire.
Neuroscientists Susana Martinez-Conde and Rodrigo Quian Quiroga and psychologist Emily Balcetis are among those using illusions to catch the brain in the act of interpreting and sometimes misinterpreting what the eye takes in. In conversation with Brian Greene, they discuss illusions involving everything from celebrity photos to police dash cam tapes to mind bending images that broke the internet.
This program is part of the Big Ideas series, supported by the John Templeton Foundation.

Having experience w psychedelics and (not related) a psychosis due to insomnia, I've come to learn quite early that what we perceive is not to be trusted. At least not automatically, our brains are a wild thing and we have less control over our "reality" than we think.
But most of the time, we function effectively with our usual perceptions.
@@tracesprite6078 being "effective" isn't everything nor is our perception but a sliver of reality
Having experienced both of your examples I much prefer the pharmaceutical version.
The delusions caused by remaining in a conscious state for an extended period of time are terrifying.
@@DavidSmith-sw5kg insomnia is a total mindfck at least, and indeed no way to live, even "just" sleep apnea can ruin ones waking life
So I ask myself who would benefit from something like that? I think I get that from hearing rich people preach Jesus' work ethics. Like I'm sure most people or at least many people would take that just for the simple reality of it. So to think, who would benefit from having someone think we have less control over our reality than we think, cause i have thought lately we have a lot of control over our reality. Like way more .
Brian is THE MAN. He has the remarkable power to understand the science and translate it to those of us who get stuck at the math!
🏋➡🏌
I can't conceive of being terrible at math.
Math is just a real easy language, it plays by the rules infinitely.
@@BoilingFrogs2050 Yeah, but that means infinite problems, yikes!
@@Edzhjus Clever!
There is no other than Brian who can conduct this type of discussion and interaction at this level. The Best.
oh Boy Brian the Poet!
That's an illusion this Brian wants you to see.
neil is amazing too
Keep in "mind" that these funky little quirks of sense perception aren't limited to vision either.
For instance, if you show two different subtitles while playing a muffled audio track, people will hear different words each time.
Also, we don't so much smell particular scents as we do *changes* in the odors around us, which is why other people smell bad but you don't.
And it probably even explains why most people have horrible taste!
Take a look at the graph called cognitive bias codex to further lose trust in your own brain.
Can be found on Wikipedia and other sources.

Has anybody else experienced that moment of horror when your brain sees something but can't connect it or false connects it into some nightmare? Usually lasts only a moment before you see what is truly there, heat still pounding.
yep lol
If there is anyone out there that has what it takes to solve this ancient riddle, it's Brian.

Listening to this made me scared of being in the dark in a brightly lit room realizing that I cant actually see the world exactly as it is is like trying to see in a dark room.
Very constructive and useful for these times of conflict and misunderstanding. Thank you!
This reminds me of someting I discovered at a very young age(circa 6 years old) that creates an astonishing and breathtaking, even haunting visual effect from repeating film-camera flashes over a period of time, while in the windowless, complete blackout darkness of the family bathroom of our house.
I have always felt so strongly that I wanted to teach and show this illusion to everyone I possibly could, which to date, roughly 30 something...something years later, still only amounts to probably less than 10 people ever(3 or 4 of which were my younger siblings) which always bothered me that I could not get more people to ACUALLY do this because I felt it was incredibly important for some kind of study that was never going to be brought to the attention of any of the right people, presummably grownups who study the brain for academic research, or something) and throughout my entire childhood, at least, this stayed as one of a handful of "mind" discoveries that I had stumbled across that remained at the time, still unknown to the world at large. Kinda a heavy burden but self imposed on some level as I was only a child and had no access to peoples who did things like research brain functionsand stuff like that... Heheh.
And I didn't imagine too many other kids with enough bored time, curiosity, and lack of enough toys, but access to and old 35mm chap camera, but no access to flm to take pictures, for the freak chance to find thmselve at the point to where the effect begins to take place noticably enough to experience the full effect of this effect fully detailed and in perfect visual clarity that gains intensity the longer(or more times) that you trigger the effect. I was maybe kind of a unique kid possibly, so I was in a position to discover the effect in its full 3d photo reality, existing omly within the human head that observes it, buy noticing that the delay between how soon you can take another flash photo concided with a pitch or frequncy that the cameras flash makes as the 2 AA batteries were recharging up whatever thingy(things were thingys in the 1980s)dimped a lot of charge all at once for the extra bright white flash emitted from the camera.
So thinking I as really smart I just wanted to spend hours in the dark bathroom, learning how to tell when the flash was ready again by siund only , without actualy having to check the "Flash Ready" indicator light to know. Interesting to exactly not anyone, nor fun, nor cool, and embarassing to any peers when explaining how to do it I think I probably became aware that it wasnt cool enough to make anyone else take the very elaborate and specific steps in the first place, then a realization that I would be admitting to a peer that I wasn't taught about this , but rather did this long process it takes before I even knew this amazing result existed, by myself, for hours, for fun...sorry I let you all down.
Hopefully I can salvage some of you! This REALLY IS THE MOST ASTONISHING VISUAL EFFECT/ILLUSION THAT ANYONE OF YOU HAS EVER SEEN!!! I absolutely garantee that, if this is not already well documented. And it can be initiated in minutes, probably less than 10 minutes to have the effect coming through quite strongly(extreme clarity). PLEASE, do give this a try, Iit IS worth it. Here is how you can do this and what the effect is:
The effect is this. After "priming" your eyes in any complete dark space with a powerful, single flash, 35mm(disposable) style camera flash, done at 30 to 60 second intervals, and allowing no other visible light to be seen in between the instant flash intervals (this is key - if theres light coming in under the doorway, roll up a towel to block all light), and make sure your eyes are open and attempt to focus on the scene around you in the instant of each flash, then after maybe a dozen or so of these intermittent flash illuminations of your immediate environment. and the subsequnt return to pitch blackness after each time, SOMETHING TRULY AMAZING STARTS TO HAPPEN about 2 or 3 seconds AFTER each flash,,,
What happens is that whatever you were able to see during the flash, I mean the EXACT field of view you experienced, whether able to focus on something or not able to because not knowing where to look(doesnt matter), that exact moment fades BACK into view gradually geting stronger and more clear until it is 100% as clear and real looking as that milisecond of flash alowed, and this imag, fully 3d just as you percieve normally(albeit with a slightly less amount of color than normal vision in lighted area, not only is pristine in appearance, AFTER the fact of seeing it has happened and ended, here it is fading from the complete blackness, back into view until it is a more perfect and pristine and stereoscopic visible image of that millisecond, more brilliant than any photogragh or video that will ever exist I think, and the image will persist, remaining in perfect clarity, for increasing lengths of time the longer you keep repeatng it, up to and even over 10 full seconds of seeing what you were looking at, but unble to move your view to anything other than that which can be amusing and funny, fun and kinda unnerving all at the same time. Particularly if you image on something familiar that is static or stationary, alweays in the same place, say, like your lavatory sink, then focus your view on where you know the faucet to be, BEFORE you make the flash so that you capture with your eyes the facte when the flash is made, then in the second or two before the view starts to reaoppear to you, turn around 90 degrees, facing the complete oppsit direction, and let the image fade in still looking perfectly like you are still facing the faucet in front of you, but knowing you are not, you will still reach out to touch it because of how starkly real and present the afterimage you are staring at with both eyes is your current spacial orientation.
Trust me, it is way cooler than it sounds to actually experience this. Esspecially if you have another person, or others in with you! Because everyone staring at a their perfect after-image view of on anothers postion in the space will be trying to reach out and touch them to verify that they MUST be right there, and nothing you are looking at will move so you jkust believe it is still the same in the darkness but seeing with perfect clarity!!
Somebody must know what this is called. Please, PLEASE PLEEEEEEAASE, end this nearly 40 year long search for enlightenment(I punned) on this very real, noticeable, repeatable, and demonstrable phenomenon is!!!
Thank you anyone who has insight into this visual effect that my inner 6 year old has been worrying that no one will ever know about at long long last.
I might even offer up one a a small but equally profound(to me anyway) childhood discoveries that I have yet to verify that anyone has yet noticed(but probably few hav), but hey...maybe not. or I promise no more mental mysteries that remain for me unamed phenomin of the working human mind!!!!!
I discovered this same phenomenon when I was young but there is a distinction between our experiences that I find interesting. For me, the effect only worked if I maintained the direction of my vision when the flash went off. If my eyes moved, or even blinked, after the flash went off, the image vanished. It did not matter if the image had already formed or was yet to form, any movement of my eyes instantly eliminated the effect and all was darkness.
This is where it gets really interesting. You say you could turn your head and still see what was in front of you. While that did not work for me, I could, after the flash image formed, move my hand into the "view" and my mind would fill in the missing information. I could "see" my hand despite it being in complete darkness. This effect was even more profound when the flash would capture my hand in front of me, and then after the image formed, I would move my hand away.
Definitely some interesting insights to be had there, and thank you for helping me remember.
I think what you are experiencing is called persistence of vision, if I understand you correctly.
From Wikipedia:
Persistence of vision traditionally refers to the optical illusion that occurs when visual perception of an object does not cease for some time after the rays of light proceeding from it have ceased to enter the eye.[1] The illusion has also been described as "retinal persistence",[2] "persistence of impressions",[3] simply "persistence" and other variations. A very commonly given example of the phenomenon is the apparent fiery trail of a glowing coal or burning stick while it is whirled around in the dark.[1]
From my own experience, a glowing coal can be replaced by a "sparkler," a non-explosive pyrotechnic commonly used by children during the July 4th holiday celebrations in the US.
I have a camera that has a feature of a flash that flashes for several seconds before it takes the picture but I never got that 3d effect you speak of. A strobe light would be next best.
I'm selling the camera if you're interested.
@kericue2065 I'm pretty sure you would have better luck using the cheapest disposable camera's flash, of any kind of "low-light" or "night" moded camera because those more advanced types takes multiple exposures, emitting multiple flashes when photographing in dark environment.
And the problem with a strobelight is a similar one in that it is designed to emit repetitive flashes at a rate that is hard to control down to making only 1 single pulse, and only at the specific instant when you are ready for it.
It must only be 1 single flash at a time and it needs to be at least 30 to 60 seconds at least, of pure dark in between each flash.
That way you are only able to "see" one(and only one) precise field of view, with only whatever exact point of focus you have at that single instance of light, to interrupt the 30-60 seconds of complete darkness of view.
Check Goodwill for a cheap old film camera that has a built in flash and runs off of 2 AA batteries. There really is nothing that will produce the effect better than on like that. One that has to charge up the flash after each shutter release.
And if there are any indicator lights like a power on or flash ready, cover them up with black tape.
Then just make sure to have your eyes open ready to focus on anything they can(will take a little practice) each time you make the flash, and you will see the effect I described so vividly it looks like you are looking at exactly what you saw when the light flashed! You can even close your eyes after you see the flash, and you will still see perfectly what you was focused on during the flash, as clear and vivid as it looked during the instant when you was seeing it. It is incredible the effect. And get more and more pronounced and lasts longer and longer, with mind-bending clarity, the longer your session lasts.
You can start to notice the effect taking hold after each flash, in maybe 10 minutes or so, but it will keep gaining intensity and clarity and creates a perfectly vivid and sustaining return view, lasting as long as 30 seconds after the flash, takes anywhere from 30 minute to an hour long session in order to see peak affect.
Remembering that once you break the complete darkness by turning on a light or opening the door, or exposing your eyes to any light, ambient or otherwise(apart from the instants of the flash) then you loose whatever photosensitivity mechanism that builds up with the lenth of time in session. So flipping on the lights in the dark room essentially kills out instantly any of the ability of the flash-in-absolute dark "sight priming" that you will have built up during the session.
So basically, set aside a good hour to really enjoy the experience. It will shock and amaze everytime!
I knew this one could not be listened to. It is a 'must watch' presentation!
Highly interesting, Absolutely brilliant, thank you Brian and the guests 👍
Can you imagine what expectations the big news sources can implant into the minds of the general populous and how easy it is to control the narrative. It colors everything we see.
I had no trouble not seeing the Dalmatian, so they can't get to me!
∘∞💕 Thank you "World Science Festival", thank you Prof. Brian Green! Thank you Susana Martinez-Conde, Rodrigo Quian Quiroga, Emily Balcetis.
That was great. First I saw the blue and black dress, but when I started thinking it's in the shade I could also see gold and white. But with the chess, chess board and moving gray square I couldn't break the illusion... And the movie with a policeman, I couldn't believe I hadn't seen as the other man was swallowing drugs. Later on it was so obvious... Amazing experience, thank you❤
I originally thought the dress was light blue and beige.
The far background is SO much brighter and more washed out than the near background, it looks like the camera is under the shade of an awning or overhang. It's frustrating that I CAN'T see it as in sunlight, even though I know that's allegedly the right answer. Maybe if the very bright washed out tone extended all the way down, it would be easier to switch?
I was never able to see the dress as anything other than white and gold.
The dark checks can be equalized by squinting the eyelids to the thinnest possible slit. It takes a few seconds before you can get both in the field of view.
Try squinting your eyes really hard focusing just on A+B and you will be able to break the illusion. or at least see they are the same color.
When you 'highlight' the lines that differentiate the illusion of perception, it obfuscates the real problem of perception, and makes it appear as if it's a trick.
Thank you so much for all the interesting shows! It really is absolutely awesome stuff!
After a cataract removal surgery I lost the vision in my right eye. For about 5 years after I experienced a kind of confusion where my mind would often not understand what visual information was coming in from the seeing eye. Oddly it wouldn’t be all the elements of a scene just a single object in the scene would be unidentifiable. A simple lamp would present as a lump of color and I would have to investigate with my hands or by moving around the object before my brain could identify it. These kinds of experiences change your relationship to everything.
Horrifying and amazing, hope you're okay now
37:04 - this is exactly how i explain the process of learning to read sheet music.
Our host's gesticulations are worth the time it takes to watch this upload.
I have a Brian Greene neuron in my brain! 😊😊 Amazing content as always, fascinating topics and discussions!
No that is a optical illusion. Always remember to keep an ion on your neurons
Fascinating. Thanks Brian, Susana, Rodrigo, and Emily!
WOW. Totally mind blowing!!! An amazing demonstration of precisely how language effects our visual perceptions. Thank you so much!
The dalmation: Could not see at all, even after repeated looks.
As for the dress. I got blue and gold, which apparently nobody else does.
A very interesting video
I had the same experience with both.
Me too - blue & gold - everyone else is mad! Ha!
Hey! I see blue and gold also!! I want to know what it means...
Blue and gold here too.
Can't wait for the next video by World Science Festival. Loved every second of this video. 🤩
I almost cried watching this, the walls do you need be taken down! God bless this officer for speaking out about an actual way to make things better for all of us! Thank you so much for sharing!
We are always looking in the past. History is our current experience and future is History.
Love this topic. Please do more on brain and perception, illusion, neuroscience of magic.
Brain Games, the docu-series on NatGeo about psychology and illusion (which is what this talk/video about). Watch the early seasons the ones hosted by Jason Sylva though as the latest ones are very bad.
no
One of the first examples of the "tricks" the eye/ brain system makes and my first lesson were the "crushes" boys and girls have even later with pop stars, models, actresses etc. In the 5th grade I laid eyes on Debbie!! Oh man she was p e r f e c t in every way. Hair/eyes/nose/ smile/ walk. No room for improvement. Then one day I saw Julie !!! Perfect.... Then I noticed that Debbie's nose was really small. Her hair was also uncombed. I have also seen this effect with cars that you are dying to go into debt for 5 years on and 1/2 way through forget what the attraction was. No doubt those who sell us "stuff" have it down to a science.
You reminded me of something I learned years ago.... I was dating a girl named Edith when I started spending time with a girl named Kate. One day, they met and my name came up. Needless to say, I lost both of them. I learned a big lesson that day... You can't have your Kate and Edith too.
Anyone in art and camera work knows how light changes what it is hitting. Your eyes change with the colors and brightness.
I really liked the set, Brian in a chair looking at three large screens, seemingly on a vast stage but probably some green screen and CGI (talk about illusions LOL) Much better than the usual Brady Bunch zoom setup.
This was a very interesting and thought-provoking discussion. Thank you!
So glad I had not seen the Dalmatian image before this. I had picked out the trees…but thought the dog’s head was a small animal.
The Face Video really sold me on this visual illusions thing. And the image of the dog. I didn't see snow at all. I thought it was a b/w of a summer day with a tree on the left and a garden surrounding it. I live on a tropical island so snow isn't in my head.
Brian did an admirable job of trying to extract objective information about the neurological basis of these illusions from a panel of guests who were largely unprepared to offer such explanations. The discussion took a southward turn when Rodrigo Quian Quiroga missed the essential cause of the checkerboard illusion (the shadow cast by the cylinder) , and never really recovered after that. Perhaps sensing the hopelessness of the situation, Rodrigo really established the nadir when he offered his opinion on the white- gold/ blue-black dress illusion.
Three remarkable guests on this episode of WSF. Thank you.
Superb, thank you!
Looks like Rodrigo made the effort to crawl out of bed for the show.
Hi, thank you for the inspiring talks!
Just wanted to mention that I see a blowup of a dog’s face instead of the Dalmatian full size figure. I assume my brain is trained to construct faces .
1:27
Much of what Plato spoke of was learned from Socrates.
Also, it is through one's soul that light gives shape.
there is no soul , we are made of atoms , catch up its the 21st century and we have moved on from the Greeks
Someone said (around 1:17:50) that one only remembers parts of a whole face instead of facial details. In this case, how do a witness of a criminal act could draw a facial composite?
Did anybody else fall in love with Dr. Susana? Her intelligence, knowledge, pleasant demeanor, silver locks and smokey voice all combined to make her appeal anything but an illusion! I could have lively repartee with a woman like that forever. Caught me totally off guard! I know; reeeee, such blatant misogyny!
Totally Babesville..
@@fretnesbutke3233 to put it succinctly, yes. Lol
mesmerizing images, professor Brain Greene always presented a Fascinating subject and I like his honesty when he talks about his experience of the subject.
The brain is just the most amazing thing in the universe
It's wonderful, thanks a lot.
It's not ended yet and you comment
@@Rastamanas Well there’s conviction for ya.
Ha! I paused this on the two-color dress illusion, which looked only blue and black to me for several minutes. Then I had dinner and watched something else. An hour later, I looked again. And then, you guessed it. I could only see a white and gold dress!
Always engaging & informative , thank you
as a legally blind person with tunel vision.. ( i am very aware of 'the world' as described'.. we just are all busy putting it all together' but (only some of us are aware of it) .. haha
Laurel's modeling the Yenni dress
Regarding the horse / seal illusion: I never see a horse; I immediately see a donkey. The proportions of the facial structures to the size and position of the ears correspond more closely to a donkey. It actually bothers me to hear people refer to it as a “horse” over and over, because they seem to be ignoring important details. Does anyone else see this?
Or...a rabbit from behind.
So, if a person cannot recognize faces anymore due to a brain injury, is there any way the brain can be taught to compensate using other parts of the brain? Or is the visual tract so unique it will be impossible to ever recognize faces?
Sure, but it only work with genital.
38:00 I understand what he's saying. Eliminate conjunctions because we got an idea where the comment is going. And that works. But the word "not" is the uno reverse card. And if you dont see it at the correct time and sequence, it can steer you off in a direction that appears correct until at some point you're left completely confused.
Great discussion!
Pacmans and the triangle example...there was presumption that everyone sees a triangle, but what if, like in my case, you see only the pacmans at first look? There was no discussion about that possibility.
I also haven't see the triangles until I've concentrated at seeing them, rather then the pacmans.
At the snowstorm, I instantly saw a snowy field. I then saw a Yorkie laying on its side
Ok, but I did find if I focused on the two hard enough I could make them the same, but then the rest of the squares blurred out and unless they caught my eye floated just beyond my perceived focus area. Even flowed into each other in my area outside of center .
I think a study of how musicians that play different instruments see the things differently would be interesting.
What of the same person who can play many instruments ?
Yep
While this is another great video, I think they are over complicating what could be a simple model. Our mind is not trying to observe reality, it is giving us the best image for us to take the best action for our survival. If it does not matter what we interpret, we can interpret both and switch between them. At a future time, whatever worked best now will be the first one given to us.
It’s a classic and ironic scientific materialist mistake
Thank you. Great video.
The dog in the blizzard picture was interesting. I hadn't seen it before so i could tell I was trying to decipher it. I knew it wasn't just noise, that there was something there, and it took about 3 seconds to recognize the dog, a Dalmatian in fact, sniffing the ground in a yard. maybe a path to his left, and a circular garden in the background. Now it will always be the snowy Dalmatian pic.
for the cops use of force, i feel like societal bias for or against police at the moment could also affect things. It was pretty clear to me the guy was resisting the entire time. as soon as his arms went in front of him he was offically doing so no doubt. It was still apparent that the guy put the drugs in his mouth and bit the officer. THEN the cop raised his hand. so if you hate cops you'll be watching him for when he "messes up" and ignore the blatantly obvious justification. if you are for police, you'll easily side with them based on the criminals actions. Sure the hand raise was a big moment, but it happened after the criminal put himself in danger and assaulted the officer.
Thumbs up if this is you.
How many times have you gone to use the restroom somewhere other than your own home and are forced to look at wallpaper (or tiles) designs which are of random spatterings that kinda resemble a face (thats the first thing we try to associate unknown images with). Then you start looking for the same image elsewhere on the same wallpaper, even considering wether on its side or upside down. Being pretty sure youve found the same image, you verfy it by matchin other images next to it. Then assess roughly how many times they've replicated that same image on rhe wallpaper.
Then you realize you just been on the toilet a half hour looking at the wall.
Was she really surprised by her questionnaire that people were more likely to give the answer that would give the best reward. 🤣
Excellent report! Thank you.
That Magician was super smooth
Hi my name is Robert and I thought of that idea for years about that what we see with our eyes (front of head) then to the visual part of the brain (rear of head) then back to the reasoning/conscious area of the brain which is the forehead .
So now all this activity happens in an instant through hundreds of different neuro-electrical pathways of input received at different times because of the length some shorter (faster), some longer (slower), perhaps a hundredth of a second apart which with a brain that is so complex it may give the feeling of having seen it before ...
All perception is projection
The objective world is illusory
That said the illusion is persistent and has rules that we can discover through science.
Thank you for a great lecture.
Thank you
I love learning. Helps me grow. Hope more ppl could feel the same, but sadly even in the technological age voluntary ignorance is rampant.
Isn't it that we are 'wired' differently, nature-nurture - Alan Turing did some interesting research regarding the different patterns in animal spots, stripes. Take siblings born from the same parents who so often portray different features. Then there's the story of the 100th monkey phenomenon.
We're certainly a colourful world, whatever way we see it.
i work with imagery every day.and i call it "ghosting" because it is basicly a connect the dot game of tiny portionary outline points. i came up with this for my art work because i was short on paper and wanted to draw a bunch of differing things. this gets into the illusionary play of shades when looking anywhere changes the perspective of the type of character you might see.cuz its actualy there.. its a bit of paradolia + connect the dot and lighting but those are matters that are truely there. the difference in spiritual focus vs just an eye is back to the platonick focus with the conscient focal self spirit beaming out to the item as plato descibed. a camara is an eye without a spirit. in other words it dont have a focal intelect to know anything of what its focusing too. just in an out is not a spirit zoom of self presents reaching out to a point. because the mind can zoom inward to the surface of the eye and or mental blankitudes while the eye is pointed and seemingly focused far off so focus is not the same as the minds self awareness of the minds focal beam because without that then its just an eye as a mindless camera unseeing what its pointed at. so i think ya should do better tword geting into understanding better the platonick self radient study because the same point just reversed the point backward into the eye and at the same time trying explain that the point of focus is different than the outer surface still does the same on the inner surface and now your imagening that the eye is tinier and still dont understand the spiritual projection of knowingly zooming to a focal point beyond the body to feel out the details by the amount of increased self presents to see more of what you was looking at without physicaly walking or leaning outward so what is that more platonic self lazerus zooming of the spiritual self vs a holow camera lens unknowing any detail of what to zoom tword and oh by the way the colors of the checkers actualy change because of the overlaping feilds as ghost lighting aka the bloom highlighters, glares have a faide over effect. the eye actualy reads that faide over bleeding glare and so of corse it tecknicaly is registered as there "when it is there" the light then faide back when its not blaired so it adopts the same shade as before the blend. with the blend light it is litteraly different. without blend then it is the same color. still has noting to do with self aware focus of self spirit to the zoom vs eye focused but the mind did not project itself to look where the eye was focused tword.. even though the eye was focused out but the mental spiritual self had zoomed inward to construct a mental puddy concept tester clone as an internal computor projection can grid even the partical depth feilds but of what substance then is the structure of the minds eye vs the surficial eyeball and how are we then able to see those images by verbal comands to follow any shape or pattern based on the details of prior experience to re'create any image weve seen and or manipulate it into anything we can describe to varify the difference in self projectional zoom verses eyeball zoom without self projectional beaming of attention to that outer eyes looking point, comparing tunnel vision vs periferial focus of the minds ,looking outer persence feilds where the outer eye can not fully see but sense the presence of specificaly because of the self sensory focal projection of spiritual sense and or self energy awareness projection of dorectional mind sensors. all that is back to the platonick depth of mind verses outer physical eyeball shape since you can also zoom backward to the surface of the eye and see the cells of the "surface" like any microscope veiw but without any other device so what is that self present focus vs eyeball focus somthing that you project outward of your knowable energy feilds ?
as far as card trick is one to realize video is always subject to stop animation in other words time dialations are always suspect to video pretending to be live vs you can push play annd pause it at any time so its not live or dorectly straight so you dont always suspect a fibbery if its told that its different but not everyone is accepting claimes at face value because some are skeptics to always suspect some foul play to video matchics vs actual majic vs trickory with slight of hand and blue is blue as long as blue is present even if the under laying material is white and gold but the present over lay is showing black and blue then the dress is black and blue based on its locational position but also white and gold in a difering location just as looking at things with a black light changes the actual colors so youll say what color is visualy there because it is presently effecting the material to show diferent so you say blue because the color blue is presently more vivid than the underlaying material but then i could say its a full range of the whole rainbow since you could change the filtering of the light with each one and youll always be entitled to acknowledge which color is curently visable even if the tecknical color is known but less visable but now its green and more but you dont unsee blue just because you can change the location of the dress till ya see nude is now hollow with xray vision picking out enough detail to see below and through the material but thats faideing through one image to see the next image that can also be there yet buried in the data of which light is more on vs the other off colors till then on color says the image is the color seen regardless of the background pattern so the image is black and blue regardless of the dress outline the fill color projects the colors that are there so you would have to admit that the "picture" of the dress is black and blue even if the dress in another place is shown as white and gold but the image is still the colors entitled to it otherwise i can ignore both and say its orange and whatever just because i can change the light and create a second dress that matches those new colors and again youd be wrong to say that its white and gold because a white can be every color and especialy a clear dress when you understand wearing a tv screen type of cloth that reveals it wasnt white and gold either until it was but its not anymore because its entitled to the visable color that is curently present but then you could tecknicly say its clear and crystaline but ahah moment of both sides are now wrong and the curently present color is what is right and generaly the clearist dresses are the best with smiles especialy if and when you can hack a dress but wide eyed i aint lookin expression of busted cuz you know you was too...
The Snowstorm blew my mind!
Simply awesome!
Look from left to right. Does the room you’re in look normal? Because it shouldn’t. You didn’t see anything at all.
The eye moves in small, sharp movements called ‘cicadas’, but it can only process visual information when it’s at rest. So, when we ‘look around’ we are essentially blind - but as having the world turn black every other second might be somewhat disturbing, our brains fill-in the gaps by making up a composite image and telling us that that’s what we’re seeing.
Strange, yet true!
If this is what our brain configures with our sight, just imagine what it probably does with our various thought processes !?
I think we use a checking process. E.g. I notice that someone is looking at me in a slightly disapproving way. However as I chat to him, his voice is friendly so I then re-interpret his look. Maybe his look is more of a quizzical look. Listening to his dry jokes, I decide that my second interpretation is probably more correct. If he becomes a long-term friend, I will have a more overall interpretation of his personality, especially as I notice that his mood varies at times. That flexibility in interpretation enables me to deepen my perceptions of people's personalities.
yet no one thinks they are easily fooled
One illusion on this, is that the host has the illusion of Bill Mahr, with a shorter haircut. Fascinating.
In the Pacman triangle example, they say you "see a triangle" but you don't, You see the correct angles of a triangle in the correct positions of a triangle which infers the angles are in a triangular arrangement, therefore it specifically "represents" a triangle. It's not really an illusion, per se, but simply a representation of a recognizable geometrical figure.
Anyone remember Jason Sylva's natgeo show called Brain Games?
It was on discovery channel
@@MarakanaCacak1989 No, you're probably talking about the wrong show.
It's a docu-seried about what this talk/video tackles, psychology and illusion, unfortunately it became so garbage after Jason Sylva left
Yeah, u are right i was thinking of brainiac on discovery, sry 😋
Thank you for the work yah guys do really appreciated cause atleast ama show it to the ones always say I'm mentally slashed.That ain't no horse I'm 100% right if it was a horse it had a neck.The black and white dots yah popped out I saw a dog less than a sec.Thanks once more
I wonder what that has to say about the states of all our minds-eye's?! (🎶Do you see what I see...apparently not!)🤔😜
How about examining our other senses for perceiving mistakes.
Well Done!
This reminds me of two things. I highly recommend the movie,"The Illusionist". People who have a talent for manipulation of other's perception can even override the fact that logic is a thing..there is a difference between truth and falsehood. They can be persuaded that under special circumstances,2+2 really can equal 17,and this leads me to our current fractured state of U.S. politics,and I'll just leave it there.
Great conversation, but my eye sees the angular distortion when the three Pac-Men are pulled apart and extended vertically. The hidden triangle is not automatically accepted and filled in by my process; it has to be suggested into place.
20:55 isn't La Ramblas in Barcelona but Praça Rossio in Lisbon!
You're not listening very carefully, 20:43, she says that "there's a similar patern" in La Ramblas in Barcelona and not that the image shown is from La Ramblas. She's probably referring to the 3d art in the Museum oh illusions in La Ramblas, Barcelona.
I'm with Rodrigues on The Dress. It's White and Gold.
But I am a trained Theatre Lighting Designer and I know how to light a scene that can look different depending on the colours used.
For example if I take a Red panel, or part of the scenery, and shine a Blue light on it, it will appear black. If I take a Green panel and shine a Yellow light on it, it will appear Red.
There's so much visual fun to be had manipulating Additive and Subtractive colours.
A propo the Police video, a similar distraction technique lost me my Passport in Bali. Just a tap on my upper arm was enough for me to miss the feel of my Passport being removed from my pocket.
I keep hearing about the illusions the Matrix, is there a web site that targets that stuff ?
Amazing
Turns out that the eye is the only part of our brain that we can see. With.
we can "see" with all of our senses
I have aphantasia. That means that I do not have any conscious imagination. I lack the ability to imagine things, to create a visual stimulus of the "eye of the mind". But that does not mean that I cannot describe things to the very last detail when talking about what I saw when I was here or there. Or that I cannot move and rotate 3D objects. Actually, I find it easy to put 3D objects together and am even better at it when slightly drunk.
So I do not see any triangle at all. I see three circles with cutouts. I agree that they could form the corners of a triangle. No argument there, but my first reaction is three incomplete circles. No a triangle.
About the black and white squares of the board. I agree but at the same time I can force myself to perceive both shades as identical. On first glance, they are being interpreted as obviously different. But when I try, I see them as the same color/shade.
The chess pieces were inconclusive for me. They looked more like if every piece was not uniformly colored. But I noticed identical patterns in the non-uniformity of their appearance. So I was expecting something to be wrong with my initial "first glance" feel. I did not see them as identical, but neither black and white. I briefly though that the images are inverted, but that did not make sense and did not feel right either. But they did not seem identical.
The moving "grey" cube over cyan an pink looks greyish only when it is in the pink area (on the left). Pause at 19:18 and compare to the hair of Brian. But it is not true grey. The average of the "grey" square is RGB 77 59 55. So it is sort of pink. And my guess is that it really is pink. Is is not grey. My observation was confirmed, just pause the video at 19:48. The RGB values are 212 172 170. It is pink. Not grey. Of course, the luminosity is different (also the hue by a tiny bit). So the supposed grey square is clearly not gray. It does not even have the same luminosity. And it "matches" the gradient background not in the middle, but a bit to the left of the middle.
No "waves" in the cobblestone, it is only a flat pattern. Not 3D at all. It looks flat because it is flat.
The "ambiguous" pictures. No problem seeing both interpretations on those images.
The faces of celebrities are really freaky. Enjoyed that part a lot. It really is a cool illusion.
I guessed that dalmatian after a couple for seconds. But I am not aware seeing the image before. Maybe I have forgot, yet it remained on a sub-conscious level. Also, I do not "see" anything. I tried for a couple more seconds and I could "find" other things as well. And I still can even though I am primed to recognize a dog. Other interpretations: a person dancing in front of a bonfire, a lying lamb, a person lying on its belly, crawling on the ground towards a patch of water, a cow swimming in water with a lot of leaves on the water surface. Also countless facial expressions, both human and animal, but without any complete head/body.
38:00 Personal observation: I can easier and quicker switch to a different language when reading, than when listening (if I do not expect a language change). Noticed this years ago when watching TV and switching stations in three various languages that I both understand. Even though I sort of anticipated a change, if it was into a different language, I did not understand the first two or three sentences being spoken until my brain "clicked in" the correct decoding of those audio inputs. Reading a text that changes languages is much easier. And I also can write sentences using three different languages as well (but all languages use the same alphabet or a combination of Latin an Cyrillic letters). I know this is about visual illusions, but auditory illusions, or to be more precise "temporary forgetting a language" are also something to consider. The question is, how does the language of a person affect how they visually interpret the world?
White/gold vs Blue/black. The question "what color is the dress" is incomplete. We do not have enough information. We can say how it appears to look like based on a very limited amount of information. The digital image is just an isolated snapshot, showing a very narrow piece of what would be the normal human field of view. We have zero information about the ambient light, the temperature of the light, any possible backlight, the white balance setting of the camera, etc. The question should not be "what color is the dress" but "what color does the dress appear to be" and why. What would help immensely is not viewing the image on a computer or phone screen or any other self illuminated display (because they all can show different light). Print the image on a real piece of paper and observe the print under different light conditions. Compare it to other pictures. Was this done in a study? Also with additional prints that might prime the viewer one way or another, that might create the desired context so that we could manipulate people to see either white/gold or blue/black? I do not claim that the dispute is caused by additive vs subtractive color mixing, if anyone would interpret it that way. Or is it a illusion like the white and black squares on the board?
The card trick? Totally obvious. The way he turns and draws the cards is very specific . Also, there were not four aces from the very beginning. ;-)
1:10:39 Or when I see people running from a bus to a tram when they transfer at a stop. They ignore everything, traffic lights, oncoming cars, they just start to run like mindless beings, right in front of cars approaching. I have seen this many times. And in once it ended in a very nasty accident, with the car ended up with a broken windshield and the person flying 15 meters in the air before hitting ground in what was clearly not a natural position of their limbs. Also lost both shoes on that occasion, each shoe landed pretty far from the scene. This was years before the "smartphone zombies". They are so focused on the display and even block out auditory clues by earplugs and loud music, that they are really a threat to themselves and others.
1:15:46 There are also tetra-chromatic humans, but only females, e.g. Concetta Antico. A very rare but well documented condition. Those few individuals can see colors that the majority of people cannot. They see subtle differences to what appears to be identical for most of us.
Thank you for explaining your Neuro diversity. Like hearing and sight impairment, other aspects of our humanity are increased, compared to the Neuro-normals.
On the card trick, it still is not obvious to me how the card handler did tricky things with his hands.
The expert woman claims that viewing everything from behind him, might show how her did the trick. So you disagree with that expert?
@@gregzeng The expert woman is an expert on magic/sleigh of hand? :-) I guess no. I do not want to give the trick away. Ask yourself: what cards did you see and from which sides? I have seen much better sleigh of hand. What so called "car mechanics" can do is truly amazing. Knowing how something is done does not mean being able to do it.
3:22
Just like the Hubble Telescope! 🤣
At 51:25, I see lavender stripes(with light and dark blue on the sides) and green. But, at 51:35 I see white and pink stripes with green.
So if I see a blue (not gold) dress is my brain sensitive to the abient lighting and processing it out to produce a blue dress or is my brain not sensing the ambient light?
Are the gold dress seer's brains sensitive to the abient lighting and factoring more information in or are the gold dress seer's brains only reading the agrigate frequency as gold/white?
Are both camps brains taking relatively equal short cuts or are one of the camps brains laboring a more complex process?
Every one of these videos are amazing .
this is a must to watch for every human being.!! and camooon explain that card trick pleasee 😃😃
I noticed right away the magician showed all the cards of the first 3 groups, and didn't showed the non ace cards of the last group.. so the only thing he had to do is get rid of the other 3 aces, and get the non aces in the first 3 groups.. I am no magician, but somehow he managed to get these aces under his left hand while substituting them with a non ace card, that is pretty awesome and takes a lot of practice, while simultaneously distracting the audience with words.. that is why I am no magician.
so he had 7 aces to begin with.. only the last 3 were never shown in the beginning
SPOILER ALERT - I'M REVEALING THE CARD TRICK BELOW based on my own observation - DON'T READ if you don't like to know how it's done ;)
Leon, look closely how he deals the cards. Never shows the faces of the 3 cards on the right (that are all aces from the beginning).
Then watch the ace in the leftmost column - after the first two cards, he flips the ace with the fourth card upside-down, yet the 4 that comes out of his hand is with a face up, not down ... Well, that's your ace - on one side and 4 on the other (that card has no back ;) - then, when he shows their backs, he cleverly drops that 4 down with a face up, never turning it over.
Similar trick with the second column, but this time, when he turns the ace, he actually turns two cards at once so the card under the ace ends up with its back on top of the ace and the ace becomes a 7 as that's what it has at the back. This time he doesn't even bother showing the backs ;)
Next column is similar, the ace is a 7 on the other side so once he flips them over, they all have faces as the ace shows up as a 7 ... He's cleverly avoiding to show you the back of that 7 by turning two cards at once over and showing the back of another card ;)
Is the incredible human mind...✨️
25:43 My guess is that there are more drwawings of horses than seals and that is what the mind expects to see. If they spent the morning looking at various drawings of seals, had lunch and came back, I'm willing to bet if you showed them this for the first time, they'd see the seal first.
@WSF Visual Illusions *Absolutely true Re: the Runners! My husband is super focused & single-minded. Whereas I am multi-focused & this difference has caused a petsistant 'difference of opinion' in our views throughout our marriage & gets more diverse as time goes on...as we get better at our individual "skills"/"faults"! (he was a skilled runner where as I could multi-task many things like a pro...lol)🤷♀️😏
Sometimes when I understand I am witnessing an "optical illusion" or a perceptual hallucination, it really bothers me that I cannot "over-ride" the error and "make it go away". No, the error persists and I cannot "will it to go away". Somehow knowing what I am seeing, or creating inside my mind is false or illusiory is not "good enough" to change the outcome. Persistence of a known error in perception seems contrary to "survival of the fittest" dogma. It would seem that "free-will" is also an illusion as a corollary argument in these limited circumstances.
How have you reacted to similar circumstances in your own perceptual (visual) experiences? Do you ever find yourself "waiting" for your mind to create your visual reality, observing the process of how visual information is selectively altered, or deleted to conform to some internal programmed narrative linking historical "expectations" within an ongoing visual construct formation?
Eye opening, no pun intended.
So @1:00:00, how did that card trick work?
There is 7 aces. He never shows the 3rd column when he places it down. He just palms and swaps the face up ones while messing with the columns. He says hes going to start with 16 and end with 16. Not that they are going to be the same 16.
SPOILER ALER
To add to what Law Ray said about the Aces in the right column, each of the other 3 Aces in columns 1-3 has a second face on the back (no actual back). He just cleverly turns them around and pretends to show their backs. See my more detailed answer to DIAMINEO above (he posted 1 week after you)
@@lawray8368 Thanks! I guess I'm a bit slow on the uptake.
@@pituspete Thanks! I must be operating at less than 8 brain cylinders.
1:01:35 MAGIC TRICK REVEAL:
((DONT READ IF YOU WANT TO KEEP THE MAGIC))
The pack is set, no shuffle and so he can already put the 4 Aces in the last column. Notice that he did not show the card on this column (card 7-8-9 are hidden).
All the open Ace have a double side with another card number.
For each column, note the 4 cards numbers: 1, 5, 9, Q
Miraculously, at the end, he now got: 4, 5, 9, Q (no more 1, but we create a suspicious '4')
Same for the next column of card. Small sleigh of hand (pretend to turn one card, but turning two cards at the same time, etc)
Well done. I can appreciate the show even if I know the tricks. For me, when I cannot understand the trick, it is less fun, more frustration.
I came to the same conclusion. It was a cool trick, though a little disappointing because it doesn't really rely on visual trickery. It relies on having a double-faced card.
55:41 he is not biting police officer, he's trying to swallow the drugs, and the cop is trying to knock it out of his mouth
Minute 20- I was literally just drawing this. Wtf
I see the dress as blue and gold
