This is just great foundational knowledge. I was taught how the checkered shadow illusion works multiple times and NEVER got it. That rectangular connection blew my fucking mind. Thank you sir.
Back in the 90s when I was in grad school, my linguistics professors were _highly_ allergic to anything even hinting at Sapir-Whorf. If you chanced to mention that hypothesis, they’d look at you like the hostess of an elegant dinner party would look at a loudly and repeatedly farting guest. I was always puzzled by that because it seems obvious to me that language and perception influence each other. I felt vindicated when I read Guy Deutscher’s book, Through the Language Glass. Great vid, by the way!
Great vid Dave! As a Russian I have to say that in Russian language light green means - салатовый (salatoviy) and common green - зелёный (zelonyi). But that not a thing in whole country.
For an extra little mind trip, start at 2:40 where Prof Dave has made the bridge, pause it, then press the left arrow once to go back about five seconds. Look back and forth between A and B while it's paused, and even though it's a still frame, the A square will seem to "darken" and the B square "lighten" Even though you've already confirmed they're the same color, your brain forgets and slips back into its original perception. Do it a few times; it's pretty cool!
9:51 the funny part is when you observe this happening in your own mind for things that are not color. How having a word to describe something (a name for it) makes it easier for your mind to "interface" with the concept. I noticed this the other day with yoga asana/poses I'm learning. Having a name for that pose makes it easier to remember the pose, as opposed to just thinking of it as "oh the one that's like blah blah blah body part position blah blah" - I guess because it's a mental shortcut? Once I learned the name, I could remember it much more completely & easily. See also the beginning of Over The Hedge where they name it Steve at first.
Excellent video as usual, this is fascinating stuff. On a side note, have you considered throwing your images here up on a darker background? I frequent your tutorials at night and the eye strain is really starting to take its toll. Thanks!
Eh, white is the cleanest and also easiest to work with since lots of images have white backgrounds and I don't have to crop anything. Just turn the brightness down on your device!
I was longing so hard for proof that the two rectangles were actually the same color in that short amount of time between you explaining it and you showing it. I tried to connect the two colors in my mind but I just couldn't do it.
@@davidkolo Everything inside the shadow becomes darker and the light tiles in the shadow have the same brightness as the dark tiles outside of the shadow. Without the shadow it would be a perfectly regular light-dark pattern.
@@lifeisstr4nge so there are two theories of color, that color is determined by light reflection, or that color is essentialized in the makeup of matter. This illusion simulates an example of light color theory.
I'm usually very good at telling colors and hues apart, better than most I know, but the shadows thing gets me nearly every time, especially when I'm tired. 😄
Brilliant presentation. I did study language acquisition for a couple of years and this is an awesome supplement (and to mention that quite a few of the primed subject tests echo some points that pop up when talking about faith fundamentalist indoctrination).
our signal processing professor at university beautifully used to say that our brain basically does fourier transformations for us since timedependent wave inputs like sound and light get processed to be timeINdependent tones or colors.
The chessboard shadow illusion also gets impacted by expectation, because we remember how a chessboard looks and that a white shade should be in the B tile
Your a great and gifted teacher bud. I hope you continue doing these straight educational videos. But I hope you always remember how gifted you are at owning conspiracy theorists. As much as you may not like it, you have a gift. I keep watching your videos like this. But I hope you step into the conspiracy arena at least once per year to spill some truther blood. Sorry you had to hear it again. But I really believe that you can keep your channel the way it is and simultaneously pwn some science noobs every once in a while. And I hope you do. Now, im gonna watch your video out of respect for you and as an offering towards a potential future conspiracy video. I'm presonally already well read in this subject, but your teaching ability is great enough that its entertaining to reingest anyways.

Thanks Professor Dave! Also, I really enjoyed your book "Is This Wi-Fi Organic? A Guide to Spotting Misleading Science Online", so I want to recommend that to your viewers. Would love to see more debunking videos and maybe even some more debates where you take on psychics, theists, alternative medicine practitioners, etc. 🙂
It's not possible to debate topics that have facts on only one side. The problem with debating the types of people you mentioned is that it's never in good faith because they always already know that their positions are unsupported by facts and they exist in the absence of logic and knowledge, therefore, there's nothing to debate.
I had no idea that wanting something (bad enough) could truly make it seem closer. I wonder if that helps with some of the mental gymnastics for those arguing the experience of telekinesis (like when they SWEAR they can do it and we assume they're not lying tools).
I have a theory that the reason we don't remeber our life when we were babies is because we didn't speak yet, making impossible for us to form memories since we couldn't describe them to ourselfs. It's hard to explain but if you think about it, it makes sense. I also believe that our perception of time is related with language. If we couldn't count time in any way using words or numbers, how would we understand it's passing? Yeah, we would still have the sun, days and nights, but I don't think we would care about weeks, months and years. We would have no way to know our bithdays, so years wouldn't matter too.
then how do mute people remember things? you're ascribing meaning to something without any evidence there's plenty of research on early memory and memory formation that you might want to read before you start making philosophical statements with no science birthdays are meaningless, you're viewing time from your modern and narrow point of view without considering how it would have been different in the past people used things like seasons/crops/animals and other natural cycles to measure time without the need for complex language, and yes to them years were very much important measurement.
I know it's a really random question but if i were suddenly teleported to a universe with 4 spacial dimensions and 1 time dimension and lets say somebody were to shine a light bulb from some point on its w axis, just beyond our perception, would all which we see around us be illuminated by that light even though the torch does not exist in the same 3d space we are in? (Not 100 percent sure i explained it well enough) Would objects in that light be shining all the way through regardless of the material or would the way it shines look as it normally would because maybe the light which is emitted by the bulb is restricted to the 3 dimensional slice it exists on? Also great video as always!
Think about a 2-dimensional being that comes to our 3-dimensional world. They are inside a a cubical room with a chair on it. They are only aware of the stuff at floor-level so to them the room appears like a square with four small wooden circles inside (the four legs of the chair). If you turn on a ceiling light, that is beyond their perception what they 2-D being will experience is that some of the floor will be brightly illuminated, some of it will be in the chair's shadow, and the inner part of the circles won't be illuminated (since the rest of the chair blocks the light). So something similar would happen to us in the 4-dimensional world. We would see things illuminated or not depending on how their shape actually blocks the light in the 4th dimension.
@@andynewman835 Hi, you asked how could we prove the point and I replied how. BTW traveling to a 4-dimensional place and testing the theory has nothing to do with faith and would prove/disprove it.
There are some. while there are a lot of studies that have shown that women are better perceivers of colours than men and are better in their spatial perception (locating points in space, determining the orientation of lines and objects etc). men on the other hand have better depth perception and track moving objects. In my evolutionary psychology class, it was told that theorists suggest these differences in abilities evolved due to the environment. They say that men were to hunt and women would store food which they would later have to take out. As you see hunting requires tracking moving prey and distance of prey, while storing things in different locations require remembering the texture of the locations and recognizing them later.
@@FawadAli_SST I think such viewing capabilites can be learned and trained. If you constantly exercise to hit a bird with a stone, your perception of distance bill become better. If you collect apples all day, you will soon differentiate between the sweet and the sour ones by colour.
@@mgsp5871 You are absolutely right. Most of such capabilities are learned. But studies show that there are biological bases of many such capabilities (and the gender differences in them). Men tend to have those parts of the brain larger than women which are involved in depth perception while women tend to have those parts larger which are involved in spatial perception as well as those involved in vocabulary and language.
@@FawadAli_SST I am very sceptical of such studies, as i have never seen one. But i have experienced the learning effect myself and know of its strength
9:33 FALSE! There are dedicated words words light blue and dark blue in German. "Hellblau" and "Dunkelblau" are the words used in German. (I am German, so I know this.)
Yes but those are more specific types or 'subsets' of Blau. You can just say something is Blau. Even in english you can say there are dedicated words for blue like 'azure' or 'sapphire' or something like that, but still ultimately they are more specific subsets of blue. On the other hand in Russian, синий and голубой are the least specific you can possibly get and they are not subsets of some overlying 'blue'. You have to specify is something is синий or голубой, just like you have to specify if something is green or blue in English. On the other hand, you don't need to do that in Japanese, you can just say something is 青い (aoi) which can be either blue or green. Another example: there are two words for 'red' in Hungarian, 'piros' and 'vörös' where 'piros' is a lighter shade of red and 'vörös' is a darker shade. And again, they are both the least specific you can get. You just can't say something is 'red' in the English sense, you have to specify if it's 'piros' or 'vörös'. TL;DR: It's not that they have different words for a color, it's that those different words are the least specific they can get in their language.
This is a lesson that can be very useful for drawing :v Woah I'm impressed every school subject seems to have a connection with how reality works. Trying to redo reality by drawing it uses these exact rules too
I was just watching your video on standing waves and harmonics. You claimed that 3D waves have 2D nodes. I have a question for anyone in the comments. Would a magnet produce a wave with this feature?
they both include the root 'blau' making them connected. the Russian words don't share any linguistic similarities. they are as different as blue and red are in German
Very interesting video, expecially the last part about the 2010 study. I have a question about this study: can this conclusion be extended? I mean, I don't know if it can be applied in reverse (aka perceiving something as more far as it actually is when you don't want it), but I wonder if that conclusion can be applied at more than just physical distance to an object and use it as some kind of "life helper": I think it would be a mistake to say something like, "if you can't reach a goal it's because deep down you don't want to reach it", but I wonder if you can trick yourself into "wanting" or "needing" a certain goal, whatever it is, to trick your mind into perceiving it as closer that it really is, in order to have an easier way achieving it. Or am I into a fallacy here?
Your subconscious is pretty dumb, you can trick it into doing all kinds of things. It's generally busy with lower brain functions and doesn't worry too much about 'fact checking' the way your conscious mind does. How much it would help you in this particular hypothetical is debatable, perceiving your goal as closer or more achievable could be helpful, but it could also blow up in your face...
*Dave can you pleasedo a video on why there are no green or purple stars? is there ANY possibility with specific gases stars are made of to make a star look purple or green to us* ? please if you can answer this in a video Dave? I really liked this video so far (im like 4 minutes in its super cool!!!) and it made me wonder whys there no purple or green stars ( *at least from what I’ve seen , maybe there’s a couple rare examples or something* )
Hello Dave I have a question and I hope it's one you could answer for me . What are all those lines in the sky ever day I look up and I see two three planes leaving these lines in the sky and I have no idea what they are and I definitely dont know what to tell my Grandson. Thank you for your time and consideration.
I don't know if it would be something your other viewers would be interested in but in the future if you've got free time between your usual content, would you ever be willing to dedicate time to making videos discussing the various paradoxes out there? I find them fascinating and I feel like your style could be rather fitting when discussing them.
I do encounter this color issue with my wife. Apparently German has more colors than Malay as we keep arguing about the color of things. To her a lot of things are just a basic color, while i see different variations.
I disagree, I really do need information about my nose. I want to know where it is all the time. But jokes aside... Another wonderful video. Thank you.
There is another funny fact. Your sensation can influence how you perceive a person. Example 1: You get a stranger to hold a warm cup of water while talking to them, and they'll think more fondly of you after your meeting, compared to if you gave them a cup of cold water to hold. Example 2: By inconspicuously touching a cashiers hand while receiving or giving money, will the cashier think you were a nicer person than if you had not touched their hand at all.
another example if you are on a date and do something that increases the other persons heart rate e.g. rock climbing. they are more likely to fall in love with you
I love this channel. I was listening to Jordan Peterson and getting into it and it’s definitely interesting and these people are these wild intellectuals I mean way out of my league … and I didn’t give a poop about what they say. It sounded like a bunch of elitist meaningless somewhat interesting info at times, that mostly doesn’t apply to life. I don’t wanna know what they know. I like coming over here and listening to Dave. The thing I did find interesting was with Camille Paglia, he was in a discussion with, it’s a famous discussion, I guess, and they’re talking about gender, which I did find very interesting, and it was great to hear them both talk about that, but all the upper level, academia, intellectual part of what they were talking about just doesn’t apply. it doesn’t matter. Camille paglia’s voice was like a shrew … Jordan Peterson sat there utterly poised in the discussion. It was interesting.
no since they both use the root 'blau' they are connected, where as the Russian words are completely different, to a Russian they are a different as you would say blue is from red
yes but most colors are linked to each other, in English dark blue and light blue are still just blue, but in Russian they are very different concepts like you might differentiate blue from red.
Sensational vid, Professor Dave.

I find them fascinating and I feel like your style could be rather fitting when discussing them.
I do encounter this color issue with my wife. Apparently German has more colors than Malay as we keep arguing about the color of things. To her a lot of things are just a basic color, while i see different variations.
I disagree, I really do need information about my nose. I want to know where it is all the time.
But jokes aside... Another wonderful video. Thank you.
dave is the new and improved bill nye
good video
There is another funny fact. Your sensation can influence how you perceive a person.
Example 1:
You get a stranger to hold a warm cup of water while talking to them, and they'll think more fondly of you after your meeting, compared to if you gave them a cup of cold water to hold.
Example 2:
By inconspicuously touching a cashiers hand while receiving or giving money, will the cashier think you were a nicer person than if you had not touched their hand at all.
another example
if you are on a date and do something that increases the other persons heart rate e.g. rock climbing. they are more likely to fall in love with you
@@corberus3119 Yes and that even includes being frightened, as long you are not the cause:-)
I love this channel. I was listening to Jordan Peterson and getting into it and it’s definitely interesting and these people are these wild intellectuals I mean way out of my league … and I didn’t give a poop about what they say. It sounded like a bunch of elitist meaningless somewhat interesting info at times, that mostly doesn’t apply to life. I don’t wanna know what they know. I like coming over here and listening to Dave.
The thing I did find interesting was with Camille Paglia, he was in a discussion with, it’s a famous discussion, I guess, and they’re talking about gender, which I did find very interesting, and it was great to hear them both talk about that, but all the upper level, academia, intellectual part of what they were talking about just doesn’t apply. it doesn’t matter. Camille paglia’s voice was like a shrew … Jordan Peterson sat there utterly poised in the discussion. It was interesting.
3:56 man, that gave me farmville flashbacks
Aren't "Hellblau" and "Dunkelblau" dedicated words for blue in germany?
no since they both use the root 'blau' they are connected, where as the Russian words are completely different, to a Russian they are a different as you would say blue is from red
Dude, that was fucking fascinating.
Damnit Professor Dave... Now I am completely and annoyingly aware of my nose.
My mom told me, our language has 8 different words of beating children with hand and she only shown us 3.
This is wild. Damn
This videos very informative but for some reason I’ve the urge to download heyday 😂😂
I wonder then if this video makes illusions slightly less or more effective?
eye enjoy this video
why am i like this
Pretty wild what the brain does subconsciously.
In italian we have azzurro for light blue
you know a lot about science stuff
In german we indeed have words for both light and dark blue and light and dark green that are widespread.
This is the second time I hear someone saying that the brain filters the nose... I see my nose all the time.
Sense of temperature
My boy
alzheimers patients forgetting the word for die and becoming immortal (because of the sapir whorf hypothesis)
sensational
ya learn something everyday
Except that’s not a moose…that’s an elk.
Sweet
Have you broke down the 911 conspiracy yet? Would love to hear your take on that
So are the bugs in my skin real or not?
IF we went back to stick shift and cursive writing we could cripple an entire generation.
@Fk Yu Let's be nice.... I have no clue who you are, but in many American schools cursive writing is not taught anymore.
@Fk Yu They do not teach cursive in school anymore, what do you think the results will be?
there are people that cant tell time with a round clock face now a days
😇😇😇😇
My language has dark and light for every color
yes but most colors are linked to each other, in English dark blue and light blue are still just blue, but in Russian they are very different concepts like you might differentiate blue from red.
wow
