The Growth of Knowledge: Crash Course Psychology #18

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.

  1. As a child, I had a phase when all animals were either cat, if they had legs, or fish, if they hadn't. Now I know why :)

  2. has anything been tried to determine if some of these are giving false positive/negatives due to childrens' lack of language skills?
    I could see a child not having enough experience with taller/bigger/more to be able to determine the proper use or even understand what is being asked. (like how they may know a deer is different from a horse but don't have the word and thus lump it into the closest group they have a name for)

  3. hank's reaction to the missing angler fish

  4. may sound like a stupid question but does that mean a 12 year old could drive a car as well as a 24 year old, both on their first try?

  5. That's helping me a lot to understand Piaget. God, can someone please tell me why by simply looking this video I understand more than in class which are so boring that I have to doodle to avoid falling asleep? Why?! How can it be that a video can tell you more than a school lesson?? 

  6. I found this video the easiest to grasp when it comes to the other Psych course videos I am just curious about the Fish! 🙂 hahaha
