Exploring Time Perception and Memory

all right so last year I did a lot of traveling and it felt like time really slowed [Music] down I was doing so much stuff in the space of just a few months and I actually remember a lot of what happened but there's is very different to my life in London where every day seems to sort of blend into all of the others and when I look back over the last few months it feels like time passed super quickly and I actually can't remember much of it so I wanted to dive into the research behind what we know about our perceptions of time why does it speed up or slow down or even sometimes feel like it's come to a complete step stand still and are there ways that we can learn to really feel time passing and really make the most of it because if you've built a life you love then you really don't want it to go by in a Flash so in this video we're going to look at firstly the different ways time is distorted for us secondly something called the holiday Paradox which is going to help us understand how we perceive time and thirdly we're going to go through three actionable and evidence-based things that we can all do to slow down time so that we experience more of life oh and by the way if you're new here my name is Ali I'm a doctor turned entrepreneur and author and when I was in med school I did an a degree in Psychology and I love researching this stuff and trying to figure out what are the evidence-based things that we can do to build a life that we love and just generally enjoy ourselves more and feel more happy and fulfilled part one time distortions okay so there's this cool study called how time flies a study of novice skydivers in the Journal of behavior research and therapy and the researchers here wanted to find out how time is distorted when a bunch of people complete their first ever Skydive now before these people jumped out of the plane they were asked how scared and excited they were on scales from zero to 100 then they got ready they put on all the gear and they went up in the plane and did the Skydive and afterwards they had to estimate how long they thought the whole experience lasted basically the people who were more scared thought that time slowed down but the people who were more excited thought that time sped up so what this research shows us is that firstly it's good to do things that scare you because it slows down time but secondly that the way that we experience time is subjective there is objective time which is objectively how long something took but then there is subjective time which is how long we perceive the thing took and subjective time can be distorted by a bunch of things so firstly subjetive time can be distorted by strong emotions like when you're happy or excited time seems to pass pretty quickly but when you're scared and about to jump out of an airplane time passes really slowly secondly boredom can affect the subjective perception of time so obviously time slows down when you're bored waiting in a line in the supermarket or whatever and thirdly when you're in a state called flow you often don't even notice the passing of time because you are in the zone you're in your Flow State you're working on something that is sufficiently engaging and sufficiently challenging okay so we know that emotions affect the subjective passing of time but what about age like if I look back on my childhood and I think of the long summer holidays I get the sense that time passed really slowly back then but as I'm getting older I have this Sensation that like time is speeding up but I want to show you what the research actually tells us about this so here's a question for you how fast did the last 10 years pass for you and you have this scale that you can rate your answer to this question on from min-2 to plus2 now this is exactly what researchers asked people back in 2005 in a questionnaire for 500 people between the ages of 14 and 94 and they were looking at how our age influences our subjective perception of time now in answer to this question how fast did the last 10 years pass for you this is what the graph looked like so if we look at the graph we can see that generally as people get older there seems to be a bit of an increase in the speed of perception of passing of time like if we look at the 14 to 19 year olds their sort of average is between 0 and 1 so they feel like the last 10 years passed from like neutral to fast whereas if you go look to like age 50 you know that the average is sort of 1 point something which means they felt time passed fast rather than neutral interestingly you can see that it sort of levels off Beyond about age 50 so it seems like 60 70 and 80y olds don't think that the last 10 years passed any quicker which is kind of good but there does seem to be a general slow increase in the perception of passage of time as we get older so why does this happen why do we have this feeling that as we get older time passes by a little bit faster now one theory around this is around the percentage of our lifespan so for example if you are 10 years old then 1 year is a whole tenth of your life but if you're 50 years old one year passing is only 2% of your life and so 10% versus 2% you would sort of Imagine a 10-year-old would feel the subjective passing of time slower than someone who's 50 and actually one other way to slow down time is to learn something new and a great way to do that is by using brilliant who are the sponsor of today's video brilliant is an interactive platform where you can learn maths and programming and AI they've got thousands of lessons and their focus is on learning by doing rather than just by consuming I've been using brilliant now for the last 5 years and they've been supporting the channel during that time as well they've got a first principles approach to learning which helps you build understanding from the ground up and it's all crafted by an award-winning team of teachers and research Searchers and professionals from places like MIT and ctech and Microsoft and Google and many more cool places brilliant helps you build your critical thinking skills through problem solving not just memorizing things so while you're building Real World Knowledge on specific topics you also become a better thinker the new courses on programming are particularly good they help you get familiar with a language like python so you can start building programs on day one with their built-in drag and drop editor if that sounds good and you'd like to try out everything that brilliant has to offer for

brilliant for sponsoring this video so that's one possible solution to this conundrum but the other one is something interesting and that is the holiday Paradox so I want you to imagine that you're going on holiday for a week and you are at the airport ready to leave but there has been a big delay on your flight so you end up having to wait at the airport for like 3 hours now in that moment especially if your phone is out of battery time is going to feel like it passes really slowly because you're just stuck at the airport with nothing to do and you're really bored and all you can think about is how slow time passing eventually though you board the plane you get to your destination and for the rest of the holiday time seems to pass really quickly because you're not thinking about time and you're always doing something new now this is where things get a little bit interesting and a little bit complicated because there's actually two different types of time perception there is in the moment time perception and then there is remembered time perception so in the moment the airport delay feels really long and the holiday itself feels really short but then when you get back home and you look back on your holiday the airport delay which felt very long in the moment actually feels very short and the holiday holay which felt very short in the moment actually feels kind of long in retrospect and this is what we call the Holiday Paradox and this comes from a book called time warped unlocking the mysteries of time perception written by the psychologist Claudia Hammond okay so why do we have this holiday Paradox why is it that sometimes the perception of time in the moment is different to the perception of time when we remember it and the theory here is that it's all about memory so when it comes to retrospective or remembered time it's our memories that help us judge how fast or slow we thought something happened in the past so uneventful periods of time with without a lot of change pass really slowly in the moment but then when we remember them it feels really short because in terms of memories we didn't make that many memories but on the other hand if you're doing something very stimulating and there is a lot of change and a lot of novelty that absolutely flies by in the moment cuz there's a lot going on it's very exciting but then when you remember it it feels very long because you have all these novel memories and this might explain why as we get older it feels like time is passing by faster cuz generally when we're younger we are doing a lot of new things we are learning new stuff we're developing new skills we're creating lots of new memories but then as an adult most of us tend not to do that many new things we tend to get into our routines we tend to have the same job for an extended period of time we tend not to have those novel new experiences so what the holiday Paradox tells us is that time in the moment and remembered time work in opposite ways where expanding one makes the other one feel shorter and vice versa so essentially we need to strike a balance between these two sorts of time perception if we want to feel like time is not passing too quickly in the moment and we want to look back and feel like everything didn't just pass by in a flash memory is our way of reliving our past experiences and reexperiencing our time and it follows them that the more discrete memories you have from a prior experience that that experience becomes expanded in time oh by the way I've got a completely free resource the journaling Hub that has a bunch of prompts my favorite journaling prompts I like to collect those it's completely free there'll be a link down below if you want to check it out part three how to slow down time okay so we're going to look at three ways that you can create more memories to make it feel as if you've expanded time and idea number one here is anchors of novelty so to understand this we can look at this study from the American Psychological Association that used a simple task to understand the relationship between routines and subjective time so here the researchers randomly split a bunch of students into two groups group one was the routine group and group two was the non-routine group and all they had to do was complete a simple task which is they were given a bunch of these different rows of numbers and in each row a specific number was underlined and the students just had to count how many underlined numbers there were but the difference was that in the routine group it was always the number five that was underlined whereas in the non-routine group it was a different number in each row now all of the students were given 2 minutes to do the number task and afterwards they were asked to estimate how long they thought they were doing the task for and this is where things get interesting the average for the routine group was 129 seconds but the average for the non-routine group was 1068 seconds and this 25% increase was statistically significant so what this test shows is that when someone is doing something that's routine without much novelty for example the routine group always looking at for the number five they feel like time has passed faster whereas when someone is doing something with a little bit more novelty and out of routine i counting different numbers each time they feel like time passes slower as we get older we find ourselves going through the same routines every day we often wake up at the same time we wear the same clothes we take the same route to work we sit at the same desk we buy the same food for lunch and yeah routines are great because they help us increase our productivity and get things done and mean that we don't have to think too much about the routine which is why like Steve Jobs wear the same outfit every single day you know that kind of idea but routines are very repetitive and they don't contain a lot of novelty so they don't let us create as many memory anchors and so our time is going to feel much shorter in retrospect when we're following routines so the key takeaway here is to seek out novelty as much as you can and it doesn't really have to be big things you could for example try learning a new skill like a new musical instrument or something you could experiment with taking different routs to work each day in my case I go for a walk in the local park every morning and I normally just follow the same route because I'm a creature of routine but you know what I'm going to exppress expent with following a different route each time maybe trying out different coffee shops different restaurants different places to work for example the more of these anchors of novelty we can add into our life ideally without like blowing our lives up the more we're going to feel like time is passing by in a more elongated fashion idea number two anchors of reflection so there is this guy called John kig and he is the founder of the dictionary of obscure sorrows and this is basically a dictionary that has words to describe emotions that many of us feel but those that are very hard to put into words and one of these words is oika which means the awareness of how few days are memorable John writes your life is a highlight reel you'd like to think that every moment has potential that there's something Transcendent hidden all around if you'd only stopped to seize the day you could hold on to it and carry it with you but the truth is most of life is forgotten instantly almost as it's happening chances are that even a day like today will slip through your fingers and dissolve into Oblivion washed clean by the tides okay so what can we do about this how can we prevent all of these different days from just dissolving into Oblivion well option number one is journaling writing about what actually happened in your life and crucially your thoughts and feelings associated with it there's loads of evidence about how journaling expressive writing especially doing it by hand is really good for your working memory but essentially the more you write about this stuff the more you have these anchors of reflection or these little memories that are associated with the thing I personally use the app day one for journaling and it's nice because today I'm filming this on the 24th of July 2024 and I actually can look at my last 3 years worth of journaling entries where this morning I was reading a journaling entry that I did on the 24th of July 2021 and it's interesting to look at that because I have absolutely no idea what I was doing on the 24th of July 2021 but I wrote about it in my journal I took a little photo and in my journal I talked about how you know we were just about to hire some new people and how I was really worried I was also taking dating seriously and i' met this girl who I really liked that i' been on a handful of dates with and I was trying to convince myself not to be too attached to the outcomes and all that kind of stuff and that's the thing with journaling that it doesn't it often doesn't feel useful in the moment cuz you're like oh what's the point of writing about it's like h i I already know what happened today but when you look back on the stuff then it's incredible to be like that's what my life was about this is this is what was going on and it really just helps you appreciate the passage of time a little bit more there's also a really good technique called homework for life which is from Matthew dicks who's written the book storyworthy which is really good and essentially the idea of homework for life is that it is a daily journaling habit where the end of each day you just ask yourself what was the most storyworthy moment that happened in my life today now I followed this for about 3 months in like 2020 back when I read the book and I still have all of these different like homework for life bits where when I look at that period of my life and I look through my homework for Life entries I'm like oh I remember these days I remember a lot more because I just wrote down just a single oneliner about what happened that day the other really good thing that I always recommend to everyone is take more photos we all have incredible phones in our pocket you can take photos with your phone you can also get a you can also get a proper camera if you would like I got this one recently fits in my pocket I have this one that flash floats around this one you know all that kind of stuff you don't need fancy cameras but one thing I generally do recommend to people is that there is something really really nice about having a proper camera that's not just your phone that you can use to take more photos cuz if you're like walking around with an actual camera and you're like taking pics with it then those pics get added to your Google photos your or your Apple photos they get geot tagged with location they get tagged with the date and then you know I've been doing this sh for the last like 15 years just taking well not 15 like 10 to 12 years taking photos of absolutely everything with a proper camera and now my Apple photos featured featur feed memories are incredible like every single day I see that on this day 7 years ago this is what happened and it's so nice to look back on it's one of my favorite things to do when I'm on toilet is just flick through whatever Apple photos has surfaced for me that day and then idea number three is anchors of mindfulness so when you ask people who are very experienced in meditation questions about how they perceive time they generally say that time feels slower in their everyday lives and actually this study in 2015 took a group of 42 people with an average of 10 years of meditation experience and I asked them questions like how far do time usually pass for you and they compared their answers to 42 people of the same age and sex but who didn't have any meditation experience and they found that the meditation experts experienced less time pressure more time dilation and a general slower passage of time which is pretty cool now we don't yet have evidence to show what's actually happening inside the brains of these people who do a lot of meditation and how this changes the way they perceive time but what we think is happening is again all to do with memory formation and this idea of mindfulness at the most basic level basically means increasing your focus on the present moment so being fully aware of your bodily Sensations being aware of your emotions and what's happening within your body being more aware of the environment that you're in and the one thing that you're currently doing and generally the things that we focus on is what we create memories of and so if you focus on these things and you are more present on the present moment that in theory helps create more memories which help to expand your perception of time and so the key takeaway here is to consider practicing meditation or mindfulness in some way or another obviously there's loads of apps that help with meditation and mindfulness but it could be something even simpler like going for a walk without your phone with you or without your headphones with you it could be something like yoga which is sort of Meditation Plus movement or it could just be that when you're doing something really giving your entire attention to that thing that you're doing rather than multitasking and distracting yourself with and eating your food while watching a YouTube video while scrolling Tik Tok on the other hand and you know all the stuff that we tend to do those tend to create a lot fewer memory dividends than just focusing on one thing and one thing at a time if you've gotten to this point in the video firstly thank you for watching secondly I'd love to hear in a comment down below what is one action point you're going to take as a result of watching this video and if you like this video you might like this video about how to guarantee that you'll regret your life which is a video about all the things you should do to make sure that you look back on your life with regret so thank you so much for watching and I'll see you next time bye-bye
