When I saw Brady had made this type of channel, I didn't even look at the videos that were up. I subscribed right away! I've been waiting for a channel like this
Awesome! Thank you so much for making a psychology channel!
I really love these kind of channels. Sometimes I have actually lost sleep wondering how this kind of stuff works, so I'm glad thats there are places to find it out :)
I like this channel Brady, I'm looking forward to more videos on it!
I love these channels because even if I've heard these things before, it really makes a difference to be told by a more trustable source than just anywhere. I now take sleep more seriously, given that this a recent video from someone who clearly knows what they're talking about. Just the thing I needed before I go to bed, lol.
This channel needs wayyy more videos. I love psychology, it's so interesting!
Anything by Brady = instant subscribe!
Sorry it's not really related to the video, but coming from numberphile, I feel here the people speaking look at you, or at us, with a more atentive look, I guess, almost as if they're peering into our soul and studying our reactions. I just love it.
Awesome another brady channel, subscribed right away. I have so many topics i love to know more of. Ego(self), subconscious, relationships(do we see other people as individuals or extensions from ourselves), hypnosis, emotions(i myself have an idea that every emotion we have is based on fear). So many! :) Keep on the good work!
you should do more about this sleep manipulation experiment. This is incredible!
I'm glad you still do the Breakfast question in order to check the audio. :)
Part 3 Your best shot of recalling things when needed, with the use of such an idea though would be to elicit that same smell when you need to recall that information, because its likely that the information learnt and the smell would have some level of neural wiring between each other because in neural psychology the no1 rule is cells that fire together wire together
You are a good person to reply to and see my inbox with some insight, other times my inbox and notifications are of something different than topics like this. Its the weekend for me so have a great day to you too.
Every time I think of a question to ask the scientists, Brady immediately asks it. Almost every time.
Very interesting! I'm happy that there are new videos on this channel!
On a only very tangential note: She keeps SUCH intense eye contact with Brady or the the camera/the viewer... made me almost feel watched through the internet.
Somehow I always shy away after keeping eye contact for a short while :\
Very interesting :) I'm really gonna enjoy watching this channel of your Brady! Thanks for such great vids :)
Amazing start, I starting learning beyond my age when I was in late 14 (i'm 16 now). The sum of the deluge of information I learnt in the past 2 years is baffling (seriously, I'm experienced at things college students take), and if you start at 11 you'll surprise yourself and people much more than I did :D
Fantastic content & excellent citations. I would be particularly interested in what Penny Lewis has to say about Polyphasic sleep!
Very interesting video!
This channel needs more views and subscribers!
I think recently an article was published that provided some information how (day)dreaming during a class actually improved the intake of knowledge.
Awesome video Brady! Thank you so much for all the work you put into your channels, they're all so interesting and fun to follow.
1:28-1:35 i know nothing about psychology but you can see her pupils narrow a subtle move in her left cheek as she realised she said "learned" in stead of learnt. bless her =P
Penny's my psyfile crush, although James Clewett is still my top Brady Haran video crush.
I can attest to the thing about the piano (and guitar.) I play until I seem to just not be learning anymore and then the next day I can play the same part better and then continue learning the song. It's a pretty neat phenomena.
I've wondered this too. I hypothesize that it's actually an optimization instead of a space preservation. If all of you're memories had equal priority, then it might affect reaction time or other instances of recall.
The man that Rainman was based off of was mentally handicapped (to the point of requiring a caretaker), so his brain probably stored and processed memories differently. People with so-called 'photographic memories' would be better candidates for such a study.
Sometimes new ideas from existing things that I am writing and thinking about come to me when I am in bed sleeping. I wake from sleep thinking an idea in a way different than I had while I was awake. If I finish the idea to some extent while lieing in bed and then get up and write the idea down, I find that when I examine the written idea later that it is always from a perspective that was new to me. Also if I do not document the idea I find it very easy for it to be gone in the morning.
I'm really loving these new videos. Keep it up Brady! :D
The first thing that came to mind when hearing Sleep reset everything,and reinforced what you'd learned was
To complete installation, you need to restart the computer. Restart now?
I usually pick postpone... I blame the internet
You think so?
I think, her style of speaking is kind of hypnotic and very fascinating!
Really Interesting Channel! A video I'd like to see is, why can I express myself in writing better than verbally, what happens psychologically?
Hello, I love your videos! I hope you do more videos!!! I hope to do psychology at university!!! These videos help so much!
Great video! Something about "consciousness" would be a nice subject for this channel.
i play guitar, most nights I sleep i imagine myself playing guitar, im playing chords that I dont know. i wake up with a tad more experience as a guitar player, really helps me experiment with notes
I think dreams may be a way for the brain to do that condensing of and organizing of memory she mentioned - perhaps by mixing and matching different pieces of memory to see how they fit together. I have nothing to back that up, however, it is merely a hypothesis.
Everywhere? Maybe it's just that great minds not only think alike, they also travel alike. ;^)
Good to see your name again.
I love the new channel. Please post more videos! I find this stuff fascinating :)
Penny Lewis and Meghan Gray, loves of my life.
its weird because what she said at the end where you play a tape of what ever language you want to learn and you learn from it. because it re-activates similar brain ares. But before she said that during sleep because the brain isnt bombarded with impulses like it is through out the day, the brain can store the memories from that day.
I'm just guessing here, but intuitively, I would think it's because when you're communicating vocally, you have less time to form your sentences. When you're speaking to people you're expressing yourself on the fly. When writing you usually have more time to think of better ways to get your point across. I'd enjoy hearing these guys going more in-depth though.
I would love to see a video about dreams (& maybe lucid dreams as many are very interested in that topic) and why it is that after sleeping 14+ hours I am more tired than I was before I went to bed :)
Please do a video on how the mind can become unconscious/tricked by illusions, etc.
For instance, sometimes we're searching for something and it's right infront of us and for some odd reason we DO NOT see it??? I would love a video on this matter. Thumbs up if you guys agree?
Part 1 Ill give this question a shot LOL. The first thing is that people with learning disabilities generally have a perception problem, in that they cannot effectively encode information to memory and so memories are not formed, this means that when trying to elicit that same information by using things like scents you've described then that information just wouldnt simply be there to be recalled.
I've always thought that dreams came from three causes. One of them is from our ancestors telling stories of hunted or hunter and the experiences of it. The next one is of memory replaying day to day life, another cause of dreaming is phobias(fears) or faith(hope) of something from either of the two. The last cause is of the collective mind or spirit realm.
One of the worst things about the mind is that if it gets worried about something, it can create the very thing it is worried about. Sleep anxiety is a perfect example.
So we should listen to tapes when we sleep to reinforce what we learned???? That ending left me hanging.
That last thing is really fascinating. Just more indication that the brain uses a lot of associations I suppose.
Hey Brady! Love your videos
This research does not support that specifically but other research indeed points to massive positive effects of power naps in between lessons. No kidding.
It seems reasonable that dreams would be our consciousness trying to make sense of the replayed memories. The part of our brain that is responsible for our consciousness is very good at doing exactly this. When all it has to work with is "random" memories it's not surprising that it may get a bit weird. =)
Good thing professor Poliakov lead me to this channel. Its pretty darn interesting. Well.. looks like I have to subscribe to this channel, too, Brady :D
This channel is awesome ! :)
That last part about the learning by association with a sensation was amazing. What I want to know is: when is the phone app coming out? :)
Part 2 But what i would say is that learnt with the smell at the time, if those smells are unfamiliar to you or are arousing then if you have perception of the smell when your asleep your recall for that information should be stronger.
you guys should do an episode about the effects of sleep deprivation some time.
Brady, can you tell these UoM lectures to tell their students about this channel?
Penny was my supervisor for a 3rd year project last year and Luke Jones is my supervisor for my MRes course and I had no idea that this channel even existed.
The most (emotion-related) memory is kept in you memory because we are connected that way for our own good (because if u felt hot, touching something u learned that that is bad 4 u), or in reverse.... That is why the scientist think that we think whit our heart! = emotion...
her eyes are hypnotic.
Haha me too! I was just like, "Hey, another nerdy channel? YES!"
I shall look into the last thing mentioned...
maybe some info about what happens to a person without sleep?
Also, Brady and psyfile, could we see some direct attention to behavior analysis? Had a semseter of behavioral psychology and it totally changed (and improved) my picture of why we do the things we do. Classic picture is the "Skinner box" -- I taught a rat how to press a lever, ha ha.
"the next obvious question you're going to ask is about dreams..."
YES! She *can* read our minds!
The unusual setting may influence your ability to fall asleep as readily as you otherwise would, but once you're asleep that's no longer a problem.
hey brady, a REALLY interesting video would be to ask these guys about LUCID DREAMING, btw, thanks for making a channel like this, i think 1/2 of the youtube subs i have are run by you :)
I was out in the woods one day at sunset when a pair of owls started hooting back and forth above my head. It freaked me out. Later that night, my boyfriend woke me up and told me I was making owl sounds in my sleep.
Could make you make a video on the relationship between language and thinking ?
Thank you :)
I agree with you about fears causing nightmares, since i have experienced it (it sucked), i just find hard to believe that memories and/or stories pass with our genes, it would need to be something extremely important, for example, our fear of the dark is believed to be caused because when the humans appeared in Africa, the night was very dangerous, so we developed it. Just remember that we arent special, were made of quarks and electrons interacting in a specific way, nothing more :)
This is awesome! More psych videos, please! :)
yay! a new video!
That's not really a detraction...
the pruning of the excess and irrelevant connections to a particular nerve cell and keeping the main link strengthened is actually beneficial to memory. What you say also has been demonstrated in rats, and it even had before and after pictures, the neuron had about ~15 connections coming off of the soma and after sleep it dwindled to ~2 and the rat became better at the particular task.
It's like clearing the unnecessary paths for more efficient travel.
can you do a video on hypnosis? its a topic that has always interested me, I would love to know more
I agree with you, maybe constant danger or a certain need over a very long period of time across generations can even make it to our genes as a way of survival or something, who knows, there are lots of things we still dont know and i hope some day we do (or at least i find out we know). Have a nice day :)
I recommend optical illusions as a next theme.
I don't remember posting this!
and perhaps add some notes to the video references some of the papers she is mentioning?
It means, it helps to sleep during pauses. Because you still have to listen to the actual subject matter.
Got tested a few weeks ago. Sleep test. I failed.
Turns out I wake up 200 times a night and I only remember about 10 of them.
I kinda get what this is about.
Very interesting video! Lucid dreams next?
My memory is awful. I mean really really really REALLY bad. I've found ways to cope with that in daily life, but yet, it's abysmal.
I also don't get anywhere near enough sleep. I seem to naturally need 10 hours of sleep, but most nights I get 4 or 5 at most, and often less.
I wonder if there's a connection between those two statements?
I know marijuana has an effect on REM sleep. I would to see some research on how memories are formed after sleep when you went to bed high vs sober. Mainly because i often use it to fall asleep, but i do think the data would be very helpful.
Extremely interesting!
Please does anyone of them know anything about Lucid Dreaming?
Thank you!
I have a question for the psychologists: If I were to, say, sit in a room full of candles that smelled like grapes, or whatever, while simultaneously trying to study maths or language for several hours - then when I went to sleep that night burning another candle smelling of the same scent - would my brain bolster that memory so that I have retained more the next day? If so, could this be applied to learning disabilities?
That test about the 2 lists of words sounds a little bit dubious to me. Did they verify that the subjects did not rehearse the first list while awake after being told they would be tested on it?
Brady, may I request a video on memory methods such as Memory Palace?
You have a new sub, this is like the "big think" channel, but more to my taste!
also, it would be interesting to see how weed has a effect on the brain, could it be used to aid sleep disorders?
I can very easily imagine how dodgy devices and advertised training courses are scam, but lucid dreaming is as real as anything else. I can say because I was there. It's definitely neither awake nor unconscious state. I can't explain something that's so far from everyday life in terms of everyday life though, you'd have to see for yourself. Or you can keep your truth about not believing, because that's what your life taught you, and I will keep my memory of it, for that's what my life taught me.
What the hell?! No!! She's obviously incredibly intelligent! She just has HUGE freakin' eyes!
what if i would put in one earpiece playing the same song over and over again.. and then when i go to sleep i will play that song to over and over again.. will i dream/remember the whole day?
cool. but Skinner used pigeons. i'm sure you know, but many may not. he actually trained pigeons to play ping-pong - which he first was able to dine out on but later ended up regretting (probably because it detracted from discussion about the real science he was doing).
like you, i also would love to see some more attention here to behaviour analysis, because - even though i'm not actually a behaviourist, per se, i do like much of what behaviourist psychology gave us.
What about lucid dreaming? For example, if we try and learn piano in a lucid dream, would that affect our skill-level in the conscious world?
She's great...at my age sleep is important!
I'm wondering how nightmares, especially the recurring kind, fit into this theory of dreams.
why do some people have great memories and others (like me) have shocking memories? also even though i know i have a crap memory, there are times when i remember something really specific from so long ago, yet i struggle to remember something my mum tells me...
I'll get right on it!
Towards the end of the video, she mentions that memories are 'tied' to sounds and smells. Does this mean that deaf people or people without a sense of smell have a more difficult time remembering things? Am I totally off track here?
What about people who can' forget anything like Rainman or other people who do actually exist, that can recall any memory at any particular point in time? Doesn't that defeat the hard-drive data hypothesis?
So what happens when you are awakened suddenly while your brain is on "memory replay"?
if i listen to a specific music while studing and then reproduce this same music during sleep does that make me "replay" my studing memories during sleep?
So, if the items replayed during dreams aid the preservation of those memories, does that mean one could use lucid dreaming as a study aid?
My guess is it only works for smaller bits of information. You're not going to memorize a whole college course by doing that.
I'm particularly interested in sleep too.
