Thanks! Used this for my upper-level undergrad cognitive psych course. Great explanation, now I can do my assignment.
Tried 11(!) sources including 4 books and here we go. 4:26 video made it all clear! Thank you so much!
Fhm
There are several tips for increasing bottom size at home
research some simple exercises online
Do some toning exercises such as weighted squats and donkey kicks.
Try changing your diet. Eat lots of protein and the right type of carbs and fats.
Wear the right clothes. Try butt-lifting underwear or a girdle.
(I read these and why they work from Magic butt blueprint website )
This is the only thing that helped me understand!!!
Struggled to get my head around this topic.. This helped! Thanks!
Day 253: I am still looking for Waldo.
Lol, let's see how long it takes me. :P
Thank you so much for this video, it really helped me understand bottom-up processing!! :D My college textbook explains it with phrases I just have a hard time wrapping my head around like "starts at the basic level of sensory receptors and works up to higher levels of processing" where I can only understand some parts and not the entirety :'c
ikr
Is it myers?
yeah it is
Thanks. I finally understand this subject. The examples you gave made it very clear to me.
Thanks! I better understand it now with your cockpit example
This was helpful, thank you
AWESOME!
You are my savior! Thanks
finally i understand this
Cheers for this mate. Really made it simple and easy to understand....
Good one
So as someone who struggles with unsual ideas when applying to programming, I find it very easy to build up from the tiny building blocks. But due to the fact that my intended dream profession involves some sort of bridging between the algortihm I need to come up with vs my comfort of utilizing building blocks to build up
How do I overcome this struggle? It feels like bridging two things together and it feels quite awkward.
Subscribed!!! This helps me with my class. You explain so a caveman like me can understand. Ill be watching more of your videos. thanks
Thank you for this breakdown. I understand better now.
A nice simple explanation. Thank you.
A really helpful video, thank you so much.
*THANK YOU SO MUCH*
great explanation!
Thank you
Just a normal picture of a “cube” actually makes the point: You aren’t actually seeing a three-dimensional object, you are assuming/projecting the third dimension onto the series of two-dimensional lines.
Thank you for making it four exam perspective
Thankyou !
would anyone know whether Biederman's recognition by components theory is bottom up or top down?
1:14 and my autistic world view I never knew I had is completely explained.
I drank what I thought was apple juice, but it turned out to be green tea and my brain was confused and frozen for a couple of seconds.
Is this the effect of top-down processing?
Yes exactly ! I think my thinking pattern is the bottom up one. It makes me feel stupid when someone summarises a concept by giving a big conclusion, bc I never thought of it this way
Why didn't I understand this from all the homework I have done. Now a 4:26 video comes in and POOF now I get it. I really understand the difference.
I can totally relate to this, a homework brought me here as well.
I'm currently studying psychology and am already preparing for the first exam. However, I'm stuck on a question/topic and can't get any further🥲. Maybe someone can help me please. "Which direction of information processing sets in when you start worrying about going to the restaurant before entering the restaurant. What role do higher-level knowledge structures play, what role do environmental stimuli play?" ... I think it all has to do with scheme and bottom-up/top-down, but I don't quite understand what it has to do with thinking before entering a place. I don't understand that at all. It's about 2 work colleagues meeting again after a long time in a course "social cognition" but both of them didn't have much to do with each other before and the woman suddenly finds him sympathetic and that's why the two meet in a restaurant (but the story has nothing to do with love).
Awesome video! Also, we have the same handwriting XD
Thia is also what seperates hallucinations and dreaming from someone's imagination.
Wouldn't dreaming and imagination be the same thing? Shouldn't it be hallucinations vs dreaming & imagination?
@@CK-jm7sq it depends on if you're lucid dreaming (Creating the dream) or if your a passive witness to the dream
2:25 Gestalt theory
Correct me if im wrong but isn't that box and circle example more of an example of Gestalts Law of Closure
Yea ig it is
What cube are you talking about? All I see is a bunch of lines inside the circles
Is that a bottoms up approach?
Is top-down similar to Gestalt in a way then?🤔
Yes gestalt principles are a form of top down processing
I got two questions wrong on a quiz because I confused these two. Hoping this video helps me not confuse them on the test.
you are the bestttttttttttttttttttttttttttttttttttttttttt
I thought it was about binary trees
(Top-Down) คือ การเริ่มต้นจากจินตนาการ สร้างเป้าหมายและผลลัพธ์ที่เราต้องการ แล้วค่อยๆไล่หาทางเดินที่เป็นเหตุให้เกิดผลลัพธ์นั้นกลับมาจนถึงปัจจุบัน โดยไม่ยึดกับสิ่งที่เรามีอยู่

Learning vs guessing
Im confused here:
So, stimulus influences what we perceive, our perception.
So, if I know absolutely nothing about something,
then the stimulus or whatever it is I'm looking at,
yet I don't know anything about, I've never seen it,
I don't have any preconceived cognitive constructs
about what it is I'm looking at.
The stimulus basically is influencing my perception.
How is the stimulus influencing my/your perception? Isn't it the other way around? That perception influences the stimulus? What I mean is: Stimuli gets created by the senses right? And those stimuli are being transducted to neural impulses. All up to this point the brain has had nothing to do with it. Then when the brain receives those neural impulses it does its brain trick and outcomes perception. And perception is subjective right? So perception is the one that influences how we perceive the stimulus, am I right? Or am I reasoning wrong?
You got me scratching my head on this comment you shared. I can say I’m about to ask an AI to make sense of what the overall outcome. Because I almost shared your bewilderment, but I thought I understood this concept, a lil .
But Big question, did you figure it out?
So many comments about how everyone gets it. I still don't
I don't get it😭😭😭😭😭💔💔💔💔I've been reading for two hours and still not get the idea of these concepts!!!
Bottom-Up: We see parts of an object. We draw conclusions on what it is based on what we see.
Top-Down: We see things. We use preexisting knowledge to draw conclusions and determine what we perceive.
♥️♥️🧿🙌
So if you go into a cockpit and you have no idea really what any of the mechanisms do, but you use your knowledge of computers, to some degree is that not top down
@Nikola Stanković exactly lol!
did anybody find Waldo?
I think he's on the far-right middle, to the left of the guy wearing many hats.
"Okay, so let's say i'm looking at the banana"
IM MONKY
i can't find waldo
Rlly shit!
i am dumb or is this just people rstionalising cognitive bias
Thank you
