How does our knowledge grow? It turns out there are some different ideas about that. Schemas, Four-Stage Theory of Cognitive Development, and Vygotsky’s Theory of Scaffolding all play different roles but the basic idea is that children think about things very differently than adults. Hank explains in today’s episode of Crash Course Psychology.

    awesome vids, though!

  • 2:09 haha I love the tfios reference!!!!

  • Too much people learn more with this courses than school because the standard education system is bad making people get knowlege

  • I want that angler fish :<

  • The Theory of Mind has nothing to do with Piaget.

  • Can you please make a video about "Dynamic Systems Theory". Really appreciate it if you could do so 🙂

  • Wow. This video brought me back to my undergrad teaching lessons. Vygotsky, Piaget and all the rest are taught in Pedagogy (the idea of teaching) 101. It was a fun trip down memory lane. I still have an undergrad Piaget book in my bookcase!

  • Recently found out a close friend is pregnant. TO CRASH COURSE TO LEARN ABOUT COGNITIVE DEVELOPMENT.

  • Dude, you are awesome. Why can't school knowledge be presented this way?? 😫

  • Please make one on Friedrich Nietzsche.

  • Cats have no understanding of object permanence…

  • "Your parents would be proud" haha, shut up, Hank!!!

  • lay

    the timestamps in the description box are incorrect, just so you know!

  • Psych midterm today lol

  • The Sacred Geometry Behind It All – Sacred Geometry Explained

  • Can you guys provide the script of the video alongside a sort of study guide of the material covered? Thank you for all the help.

  • thank you so much for helping in understanding alot of lessons especially in psychology & psycholinguistics. thanks

  • I like you …you make hard things easy to understand 🤗

  • I'm so excited for monday!!!!!


  • when i was younger, i used to call horses "unicorns" because i only knew unicorns and not horses,, im crying

  • AP exam tmw and crash course is saving my life lol

  • you talk toooooo fast

  • a friend's son, who's about 1 year old or so, obviously doesn't quite understand the shape box toy (cubes in square holes, balls in circle holes etc). He does understand that the circle hole looks larger, so he tries to cram all shapes in the circle. when he can't he just makes the hole bigger. by that, i mean he lifts up the lid, drops the object in, and closes the lid again xD I turned to her and was like "this kid is going places!"

  • piaget (esquemas) : dice q los errores de los niños.

  • I'm only 7 minutes into this video and you've summarized an entire section of a chapter that is taking me hours to read all the way through. I almost want to use my tests scores to quantify how powerful this form of education through instructional, public videos is… the vocabulary is astoundingly similar, which makes sense of course assuming I can watch these videos and score well on the chapter review guides. Of course I'll have to read the textbook afterwards anyway to verify the true preservation of information. So my hypothesis would be I really only need the testing software that the online services provide from the textbook company and the videos to succeed on a real test and I can make a reasonable judgement before I take said real test by accounting the inconsequential but stated indispensable testing material and compare it to my textbook only tests I've already taken.

  • A M

    thanks very easy to understand than my book 😃 but can you please slow down a bit I felt like a train was running after you😅😂
    other than that great job

  • Thank you!❤

  • Damn if only my parents saw this video, I would of turned out just fine ):

  • Damn if only my parents saw this video, I would of turned out just fine ):

  • This video is helping me a lot in understanding the concept of cognitive development for researching purpose. Greatly appreciate

  • i <3 U

  • can you speak slowly to understand you

  • Peekaboo Master?? Bahahaha, I couldn't concentrate again after that.

  • And so, Hank and his missing anglerfish were reunited at last. Awwww.

  • Great video, but i was wondering why you didn't discuss the other side of the debate, the side that believes that B.F. Skinner's view of continuous development is how children develop rather then piaget's view of discontinuous development.


  • yyeess!!! I knew his brother was John

  • I let my two year old nephew drive up and down our dirt road and he even uses the turn signal when he turns into the driveway, he's capable of empathy and understanding and playing blackjack so he's probably in between the second and third stage defined by Piaget

  • Great content but I can't help but feel annoyed sometimes by your 'goofy' delivery style

  • Maybe the younger kids were over thinking the answers and were like, but those coins aren't exactly the same and the two beakers don't hold the exact same amount of fluid.
