- Change Blindness: How can we miss big visual changes that happen right before our eyes?
Psychologists who study the fascinating phenomenon of change blindness know that merely looking at something is not the same as actively paying attention to it. As the demonstration in this video shows, people can be blind to significant changes in a visual scene that are obvious to someone who expects that these changes are going to happen.

I didn't notice the two guys at the beginning were different people, but I did notice he went from collared shirt to undershirt.
the same and i still dont see they are two different guys until reading your comment lol
the same and i still dont see they are two different guys until reading your comment lol
same
Me too :P
I also noticed that was a strange place for a phone.
I just read up on this concept in my Psych textbook and decided to find an entertaining video demonstration; then, you got me right at the beginning of it! Did not see that coming.
Even when the two blokes at the start are shown side to side, I can't tell them apart!
ikr -_-
That’s cuz white people all look the same.
the only thing i noticed was that his shirt changed from a button-down shirt to a t shirt
Yeah, it’s face blindness. I have it. Can’t tell people apart sometimes! I just memorize their clothes instead!
@@bittersweetrain1740 And their hair. The second one is clean shaven.
It makes some TV shows really hard to watch.
Damn, the guy at 2:13 was having NONE of it.
HILARIOUS
As I man who doesn’t like looking at other people’s faces. Sometimes I’m don’t even know who I’m talking to.
I've watched this 3 times and I still think the first two men are the same person.
Maybe the trick was trying making you think they were different people. Trust nothing!
ikr. I'm so confusedd🥺😥
One's more fat faced than the other.
Check the facial hair.
and thus the science behind stunt doubles..
1:55
That lady is my dad's girlfriend, just found out a few minutes ago when she told me i'm still shocked, considering I just watched this video in psychology class about a month ago without even realizing it was her. That building behind her is where she worked, now she lives in wisconsin with us.
Alex Kister omg no way
The first test was cheating because they chose two people that look alike even when video is paused and looking at them at the same time. 😒
I thought the same thing!
I think it is the same guy just no beard
when that bald guy kept talking about subtle changes in the background, i kept looking for something to change
HAHHAHAHA
even when they explained they were different people.. they looked nearly identical!
Very cool.... and the guy at 2:13 will be taking crap from nobody today.
3:20 "Faulty memories can *wreck* havoc." No, but they can *wreak* them.
Its not always about missing the changes. We accept the reality we are given. From the fantasies of childhood we learned that our reality can be different than we perceive. So when something changes we've trained ourselves, with the help of people like parents and friends, to ignore what we believed was true, and go with what we see now.
We get so good at it that we often don't even know we're doing it anymore. ;)
2:17 the guy just walks away
Naaaaa you don't sY
nah you didnt remember it correctly. He "struts" away
What guy, I don't remember any guy!
I don't actually remember people's faces very often because of short conversations or lack of interest and when I come across again I try to think that they seem familiar until I recall the last meeting. Seems this is what it tries to explain.
Just imagine how social media is ruining us with our brain already slacking
PBS, please add closed captioning to your videos so they are accessible to everyone!
You can turn it on with google chrome. Oh, I see 7 y old comment
The guys at the beginning look exactly alike, even when you show them side by side. They should have chosen people with different looks.
Exactly alike? Facial hair and chubby cheeks are definitely enough to tell two people apart. The whole point is that there isn't anything so obvious as to trigger a "there's an inconsistency in this story" reaction in your brain, but you'd have to be looking extremely casually to not be able to tell the two of them apart when you're aware that there's two people
imprecionante, solo en 4 minutos y siete segundos , pude captar y aprender algo grandioso
the two guys at the beginning look like the same person, even next to each other. doesn't quite fit the intended parameters of the experiment.
Yeah, I thought exactly the same.
More than likely they're twins
You can tell hes one of those people that takes even the smallest joke as a seriously personal attack and freaks out like a baby.
That's not true. They are distinctly different in facial structure if you just pay attention to it... Not to mention that the first guy has stubble, and the second doesn't ;)
They could've just made it easier on us and kept the first guy white, and made the second guy black lol
In the start, The only change I noticed was change from Shirt to Tshirt. Both person looked kinda same to me
taking coursera?
@@sahilrao8182 i am lol
Very well made video, thank you.
Yes, I've noticed
I still couldn't tell it was two different people when he told us & showed them both on screen at the same time... Uh oh.
I did think the 2nd guy looked different, but just figured it was because the first clip showed him in different lighting, and a different angle. I thought it might be a different guy, but based on the couple seconds shown, I wasn’t calling it out. That happened to me with an old girlfriend and the one-two Switcheroo.
Those of us with (inappropriately named) attention deficit disorder are drowned by a deluge of information.
So THAT'S why my cousin can never remember what happened in Monopoly...
I always win at Monopoly too.
Those two men were so different!
Yea but you didnt notice the shirt changed too
Eat Your Cereal also the flip flops!
And the finger nails
The unreliability of eye witness testimony is often compounded by the trauma of the event/crime that was witnessed, and the effects of the stress response in our bodies.
In the opening scene the only weird thing I noticed was that the phone had a cord attached to it. It must have been 1992 calling.
Priceless was College girl who was pressed on how she so confidently knew College guy was swapped out with an older brother version of the first? She coyly admitted to having designs on the College aged one.
You "wreck" havoc? What's left after the havoc is wrecked?
It's possible that in the experiment the people who recognized the switch were sexually attracted to the first guy so took a mental note of his face.
I have a detailed visual eidetic memory. I wouldn't go as far as say photographic memory because I cannot recall things I didn't initially perceive. That is what they are really indicating here. I will say however that I do notice inconsequential things at times subconsciously, like the fact that there are 12 bars in each section of fence. Why do I know that? I have no idea. I just remember it. I don't know how people don't notice the guy's hat color changes from black to blue or that one has jeans and the other is in shorts and flip-flops. This things seem obvious to me. I actually remember customers I sold computers to 24 years ago. Again, not even sure why. That's part of the reason I got out of the service industry.
I noticed that the guy in the second shot didn't have the same facial hair as the guy in the first shot, but didn't realize that it was two different guys because I'm bad with faces as it is.
I didn't see 2 different men at the computer, I saw they were wearing different shirts. One had a dress shirt the 2nd one had a T-Shirt on.
That just seems like the worst possible way to test this. Having them walk directly between two strangers while holding a big ass slab of plywood? Why not just have them step out of the room for a second or something smh.
they picked twins for the experiment omg
the first guy had dimples and the next one did not have dimples and i noticed it immediately due to my job
I believe what changed about in the experiment at the beginning of the video is at the second clip the guys shirt changed from a collared shirt to a crewneck shirt
This was done by Derren Brown long time ago.
Sad thing is I always fo remember most and I replay positive and negative outcomes in my head always so I have plans lol
we talked bout this video in sunday school-its a cool experiment:)
Even when they showed them side-by-side, they look the same to me.
Wow Brands also used change blindness for their advertisement
The first guy in the video look exactly like the guy who picked up the phone, just with a different white shirt lol
The only difference I see in the first two people is their shirts. They look like the same person. And for the wood switch, why would someone expect a switch if a different stranger dressed the same continues the same conversation. This is more like a gaslighting prank than a recognition mistake. The guy at 2:13 who bolted after the switch probably recognized the switch and thought he was being set up for something and wasn’t playing that game. He’ll probably never help someone asking for directions again. Who memorizes every little detail of a random person when he’s directed to look at a piece of paper. This is a “biased” experiment. And as far as remembering every detail of literally everything in the field of vision on a public street, the scientific results are “No 5hit Sherlock”.
Because of this video we now all have an unconscious bias towards paying attention to those who are infront of us lol
Go UIUC!
at first all i noticed was the shirts the two guys were wearing were different! they look like the exact same guy !
the guys at the beginning look the exact fucking same. that's just... blindness.
It was his tee shirt
+Tdasilva 0.0 i didnt notiuce untill you said so lol
PSychology is god damn interresting you can troll ppl. all day by just using your knowledge against em XDD
I think they're rather distinguishable. Chubby cheeks, wider-set bone structure, facial hair... The first guy certainly doesn't look exactly like the second guy.
Find another word, don’t use blindness coz it’s not blindness.
Am I one of the few that noticed that there were two different men in the beginning?
Nah, I did too.
“Wreck” havoc? It’s “ wreak”..
0:35 I still can’t see that they are two different guy even when putting the two scenes together, is this racial face recognitive barrier or do they really look alike?
What f do ones it mean for the ones who’d that would never work on
Who came here from the book called Psych Experiments by Michael A. Britt?
so the brain uses like the computer uses cache. and we often see our common surronding as a information previously stored when we walked down the same path.
then i think it explain why we get more exicted and see more closely when we are on the new place or new town.
damn!!!!!!!!!!!
Check out Derren Brown
0:34 wasn't he the guy at Sandy Hook?!?! PROOF OF A CONSPIRACY!!!!!
This concludes my one man show 'Internet Dumbass'
First guy had a beard
did anyone spot the gorilla?
I didn't notice it was two different men. I did notice they weren't wearing the same shirt. *shrug*
3:20 It's 'wreak havoc' not 'wreck havoc'.
More less if the pedestrian doesn’t find you attractive then they will not notice. 😆
Yeah, to me too :)
0:35 ummm... even side by side they look like the same guy
what about gender as a foctor? can the gender of the participant impact the results?
Apart from being two different men, they are wearing different clothes! The one is wearing a tshirt and the other one a shirt
Yes, but you completely missed the moonwalking bear.
This doesn't work if you're familiar with the people or place. Being that close to the guy I'd notice since I'm expecting an attack I'd be reading his face to try and figure out his intentions. If one smelled like anything I'd notice the change.
Gus? Is that you?
Or trade an Attractive Person for a Not so actractive person... or the other way around!
Cheers
PBS videos should be closed captioned :(
Anyone else here because of Between the Buried and Me's song Obfuscation?
Trans phobic content, right? I can’t believe he would say we might notice what sex someone is. “Trans women are women,” right?
Who is here from Prof. Lanaster?
"Don't worry if you didnt notice its two diffrent men"
Hunny, I'm a gay man, I noticed.
Imagine watching this video and still believing democracy is a viable form of government.
Survival of the fittest.
Who is here from Jordan Peterson? 🙋♂️
wow people didn't notice when two people switched spots hahaha
why the guy wearing the green cargo pants have to walk away like that hahaha!
Mugic
that man for sure noticed the height..some inferiority complex!
the face full1 then 2
this is why eyewitnesses are notoriously not accurate
Wow. This is sooooo culture bound, like the rest of the Western pseudo science of psychology...
Looks like the same white guy to me. Only the shirt changed and the beard. Still looks like the same white guy. Lol
Smh I really thought "Why these white dudes all look the same"
ok who watched this vid im from cambridge
4
Nah man its just that i cant tell white people apart
Only the sheep don't pay attention.
How the government is able to conspire against you...
So if i notice that its two different man, is my brain not doing what it should be? 😂
As someone who is partially sighted and socially anxious, I pretty much never know what anyone looks like, even if I directly interact with them.
Same lol
How about switching the Asian guy for a black guy, i would love to see how far can we push it.
Real Life trolling
In another recreation of that experiment they tried different changes and it totally worked. The first guy was white and they changed him with a black guy and an Asian looking women. But they don't show the cases where it doesn't work.
In the very first example, even after they showed the men side-by-side, I couldn't tell them apart :(
I have been a professional hypnotist for over 23 years. The phenomena discussed here are real. What the researchers do not seem to account for, however, is the ability of the human mind to generate both positive and negative hallucinations based on deeply-held expectations. From my perspective, what I would say is going on is that people are hallucinating details that align their perceptions with preconceived notions of what they should be experiencing. For example, in the first clip with the guy typing on the computer, I would argue that the reason many people do not notice they are two different people is because the human brain actually alters the appearance of the second guy in order to make him look consistent with the appearance of the first guy. This is also the same mechanism behind optical illusions: Your perception of what you are seeing alters according to what you expect to see.
I would have loved to see race played into this. It’s true that white people pay attention to and can recognize white people more, likewise with black people recognizing and paying attention to other black people more. At least that is what I’ve heard, I’d love for someone to do this experiment.
That said, the two white guys in the first sketch are the same person as far as I'm concerned.
Its been found its dependent on the race you grew up with, which is usually the same as your own, however when those of a different race have been adopted into areas with predominantly one race they tend to recognise differences in that race easier.
I saw another video where a white person was replaced with a black person and they still didn't notice!
