When designing software, a general rule of thumb is that any response under 0.1s is perceived as instantaneous; anything longer is perceived by the user as there being a delay. So for example if you have a button that does some calculation and then displays a result, if the calculation is faster than 0.1s you don't need any additional considerations and can just put up the result whenever it's done, and the user will see it as being instant; if it takes longer than that, then displaying a loading/working mark, changing/disabling the button or some other method is required, otherwise the user is likely to press the button again, or at least be confused why there is no response.

Just want to say thank you for providing such engaging, insightful and rich content. Just discovered your channel, and I am yet to view one of your videos that I did not like. I appreciate them all. Keep up the quality work, and the integrity of the content.

My cats definitely understood causality when they decided 5am is breakfast time.

There's actually a nice demontration of your last statement in computer science. When parsing a text, and turning it into gramatically structured information (like making computer code into a program, or parsing some parts of human language into nouns and verbs and so on), it turns out only the simplest grammars can be parsed one letter at a time. The moment your grammar grows the least bit complex, you need predictive power of a portion of the local future to decide how to interpret the current symbol. You don't know if "s" starts a noun or a verb until you've read the entire word. So you need to delay that choice, and look ahead in the text, to find that future information you need. That's sort of what our brains are doing here, right? Delaying the interpretation of the present until a bit into the future where it has more info to base it on. It almost sounds self-evident we'd evolve to work like that.

As a racecar engineer I have always been fascinated by this concept and how high intensity sports are able to reduce the lag in ones perception of time. Many people have experienced time slowing down when they have been in high intensity moments and I often find that it is when people have a good understanding of the physics of what is happening to them. The brain can then somehow increase its frame rate to absorb more information about how the event occurred. For sportspeople, like racing drivers, this experience happens in real time and often. It is when they fully understand what is going on around them and are able to process the experience faster, it allows them to achieve almost super human feats. I'd love to see you do an episode about this, hit me up next time you are in Melbourne

I would say brain predicts and follows movement very good. The white flash stays in our vision for a little longer than it actually appears. Like a short time memory. Combined you see the white slightly above the green ring. Brain is trained to keep things in the picture even if they disappear (they usually shouldn't do that). It serves us nicely in our daily routines.

I thoroughly enjoyed this episode. Or did I enjoy it later.

Fantastic as always! As a life-long hobby film maker and professional musician/sound designer for image (didn't mean to hand out my CV :-) ), I know these things inside out. Often a sound needs to be shifted slightly in time to appear being in sync. The natural delay of sound of course doesn't apply to telephoto shots (where people are far away): the conversation needs to be in sync and not delayed - since our eyes are not telephoto lenses. Another interesting thing happens with artificial sounds which are not short claps or clicks, but rather impacts or punches. Sometimes these need to start just a little early (not late!). Last thought: one sound might appear fully in sync when you just watch the short scene - now start the video earlier and watch in context - it might be slightly off again. Very likely expectations and brain mechanisms. Thanks for reading and thanks for another great video!

I've been binging on your channel. It's so informative. Thank you

Interesting concept, alot to think about, questions to ask. It's like our brains have a buffer.

Still at 0:02 and I pressed thumbs up. I trust you.

Your explanation for the specious present reminds me of AI architectures that have temporal coherence. An input step consisting of multiple images in a short time interval around that instant. The AI needs this to make sense of video footage. Feeding the images separately one at a time will introduce flickering.

Great Video! Thank you. :)

Thanks for a great video Veritasium. I would be very interested in someone investigating what the implications of our perception happening over an interval and not an instance would be on the Copenhagen interpretation of quantum mech. Does a wave function collapse in an instant or over a small period (seeing as "observation" is not instantaneous)? Does this also have implications on the energy-time uncertainty relation?

I love counter intuitive truths that make you question the nature of reality. Great video.

An interesting idea came into my mind as I paused the video at a random moment. Perceiving the world instant by instant would make us notice all the funny and stupid faces we do as we speak, wouldn't it? :)

years ago I got an early digital camara, and I was once asked if I would take some photos at a party of an older woman who was to give a talk, and to only take them as she gave her speech as everyone else watched(so all their backs were to the camara and no party goers faces in the shots) I tried and tried but could not get a good photo of her where she didn't look hideous(the host finally came up to me and asked me to stop because I was taking too many pictures and that wasn't discrete) .... to look at the woman talking she seemed perfectly fine in our 'persistent present' where perception of her was "smoothed", but frozen in one instant at a time as her jaw, mouth, and skin contorted in odd disconnected ways didn't work - I refused to give them any of the images I took, and blamed it on a camera problem(which I guess it could be) but said I'd retake an image of her if she posed still

5:16 For me both times I noticed the green outline matching the white circle, leaving no black gaps. Based on this I don't think the things that happen during the delay between the flash and you perceiving it have an effect on what you actually perceive, only on your explanation of what you think you perceived if you didn't quite catch it and your mind has to fill the blanks.

I am really big fun of optical perception and brain relation; i was expecting a philosophical video and i enjoyed this quite a lot.

*Hey Derek*, Great video, very insightful. There are tho things you mentioned I do not completely agree yet: 1) The test of David Eagleman clearly Eliminate the hypothesis that our brain predicts where the green cycle would be, yet I'm not sure yet that this effect is caused by a processing delay. It can be caused by the refresh rate of the retina. we all know that when we see a flash of light, it takes few milliseconds for it to be erased from sight. So we might see the "past" white circle inside the "present" green circle. Do you have in mind any method to verify it? 2) While the specious present is a collection of sensory perceptions stretching over a tiny period of time, I think we experience them all in the present moment. That is, it takes some time for our senses and brain to process the information into a mental image, and it combines things that might have happened in various moments, but experiencing that mental image happens in the present.

Hey +Corvaire Wind , I know that what I wrote is not very clear. Let me try and explain it differently. Think for example of the situation when you freeze a video containing a fast movement. You would not see a clear image, but a smeared photo. This means that the photo presents an event that happened during several moments in time, yet you perceive this photo instantly. I'm definitely not saying that the specious present isn't real, I only want to refine the understanding of it. We perceive in a timeless moment (present) a construction of an event that happened in various moments. We cannot live but in the present, so all our experiences are in the present, yet they present events that took place in time. Even a still image is not really a representation of the present moment since at the moment the picture was taken the electrons of the atoms in our body made some several billion cycles around the nucleus. If we could really perceive the tiniest measure of time possible, we would probably see emptiness.

was it just me or was there no flash in the flash lag animation???

+harvey288 You must be watching at 60 fps. At 30 fps it gets skipped, because the flash is only 1 frame long. You can adjust the fps in the quality settings by clicking on the gear in the lower right corner of the video

OMG! Than you Andrew Ding, (5 years ago). I thought something was wrong with my eyes! I rewound this video a bunch of times, and could never see a flash. Then, I scoured through the comments, hoping someone else hadn't seen it...and, there you were...with an explanation. I slowed the video speed down, and saw the flash, lol! Thank you!

Now, this was a great Veritasium episode! 💢💥

The first flash I didn't see anything, and the second time I saw it perfectly inside the circle

Awesome video

Mr Muller, I so love your videos. I wish that in this one you had covered the fact that there is no such thing as 'now'. All you have to do is ask the simple question: how long is 'now'? Because of the infinite nature of numbers, there can be no answer. Is 'now' a thousandth of a second? A millionth? A billionth? A billion billionth? It is like the classic problem of two objects never being able to touch. This is one of my most favorite subjects, and I think about it all the 'time'. Because time itself is an illusion. Since there is no such thing as 'now', there can be no such thing as 'time'. All that mankind has managed to do about the apparent existence of time is to get clocks all moving together, or more or less together, which is very convenient for when you want to meet somebody etc. But time is like gravity: an assumption with no basis in actual reality. What there is, is DURATION. Things continue in the same state - or give the illusion of continuing in the same state - and this gives the impression of something called 'time'. Even duration is an illusion because nothing in atomic reality ever stays exactly the same. But anyway, I believe that an extraordinary state of enlightenment is possible the moment you perceive that you cannot live 'in the moment' because the 'moment' is ever escaping into the infinity of numbers. There is something exhilarating about it, something refreshing.

I saw it immediately but I'm a musician. And kudos for the Star Wars reference! ;)

Hmm... I see the flash inside the ring. :/

because you were focused on it, at least that's my case, the experiment acquire you to look at that red point.

Same, was looking at 1080p60. Could also clearly see the lag on the other test, but that most likely because of experience.

I know this video is from 5ever ago, but I love the “who shot first reference”

There is a guitar/music effect called "doubling" in which the original signal is sent a second time but set at a delay of milliseconds. This gives the auditory illusion of two instruments playing the same thing simultaneously but with that slight delay of human error, giving a fuller sound. Anyway it's interesting to set the delay as short as possible and play something as brief as possible or even just tap or scrape the pick on the string, and it gives you an idea of what the time gap of milliseconds feels like. I play a side scrolling racing game, one mode is drag racing essentially, and the finish time is given to three decimal points (the actual calculated time is beyond 3 decimals but the time displayed is just up to 3 decimals). You can just barely win but you can SEE and perceive that the nose of your car was ahead of the nose of their car, and then you come to see that you won by 13-thousandths of a second or something like that. So it's really amazing just how quickly you can hear and see and perceive things.

The flash appeared like it was directly in the center of the circle to me. I think this means I play too many video games...

In the first expierement I saw circle appear where it did appear, in the second one I saw it appearing on top!!! I'M FEELING AWKWARD!

i love your videos

As a musician sometimes I'm recording with a little bit of lag due to the buffer size and unconsciously I start to play ahead of the beat to play on time, then when I adjust the buffer size to get rid of the lag it feels like the button-light experiment, as if sound came in before I played the notes

I noticed immediately at the start of the video, that *something* was off, I couldn't tell what, until you mentioned it specifically though. I also think that my tolerance for video/audio sync-mismatch is shrinking the older I get, or maybe the more experience I have with better-synchronized video. When I was in my teens all the music videos I watched on MTV seemed perfectly synchronized to me. When I rewatch those videos *today* (about 15 years later), they seem to be *all* out of sync by *a lot*. the flash experiment caught me off-guard, I didn't see a flash at all at first, because I was concentrating on the red square as you said. when I watched it again, I saw the flash and it was perfectly centered (144hz monitor, 60fps video). in the second video, it was also perfectly centered. does it matter that I am wearing glasses? at least not noticing the flash could have happened because my brain is used to discard visual information from the areas my glasses won't cover (the edges of my vision).

So... apparently you have to watch in 60 fps for everything to work. And even then, all your gaming on high refresh rate monitors may have given you freakishly good powers of perception.

I would like to perform an experiment with three configurations of the flashing circle: the first making full rotations, the next making the bouncing half rotations, and the last starting at the flash point (sans flash) and randomly moving clockwise or counter clockwise and disappearing immediately after the flash. This is because the first flashes in both cases appeared in the circle for me, while each subsequent flash appeared in either the upper or lower half as he described to be the typical perception. I personally suspect it's a mixture of predictive pseudo-vision and persistence of vision where the flash seems to linger when the circle has already moved on into the next frame.

This is my favorite video
