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.

People who watch this: - those who are interested in the subject of psychology, for entertainment purposes (5%) - psychology students who are frustrated with their professors and are in the learning process for the next exam (95%) awesome vids, though!

@Darticus42 10 лет назад

Alex Sitaras Heh, on the internet barely anyone is civil. I've seen many arguments on their channels about related topics where people's "arguments" degrade into curse fights. The audience is probably more civil, but in any conversation (RU-vid is a conversation too, from video creator to audience and back again through comments) it is best never to talk about money, politics, or religion. And philosophy grazes (at least) two of those three. Although I think it would be really cool and enlightening, I somehow doubt that others would think so. :(

Can you please do a video about emotion, why some people are more emotional then other and why does some people feel "less" emotion then others?

@ellisartwist 10 лет назад

well the less emotion could be a symptom of depression. depression isnt necessarily being sad but rather a lack of feeling. this is why some depressed people cut themselves because they want to see if they can still feel.

@NeoChromer 10 лет назад

elazer twist woah.. didn't know that!

@netialouis527 10 лет назад

Emotions aren't associated with depression. I remember reading somewhere that depressed people cut themselves to gain some control of themselves. Depression causes some emotions, but emotions don't cause depression. XD I can't explain it, just ignore me....

@tomshraderd4915 7 лет назад

Well, I'd say it's because he does simplify it a lot (it is a CRASH COURSE after all), which probably helps. I'm studying this stuff for my exam right now and we have to go into MUCH more detail than that (also I'm a bit sad that Vygotsky is only barely mentioned, but I guess you can't have it all).

When I was little, my parents both worked most of the day, so I spent a lot of time at my grandmother's house. I started calling my grandma "mamma" like I did for my mother because, in my small child mind, they were the same kind of person because they both played the same kind of roles in my life. I knew that one was my grandmother and the other was my mother but they were both "mamma"

@mekey0709 10 лет назад

Hello, while i think that my comment will go unnoticed, i have a suggestion. That suggestion is for the Crash Course team to upload these and new episodes of Crash Course on itunes as podcasts. Doing this will allow you to reach a broader audience and demographic alike. As a result they may even subscribe to your youtube channel. Any way, great work on these and i hope to hear a response, albeit big youtube accounts seldom reach out and respond to their viewers.

@AmandaMariePingelRamsay 10 лет назад

***** +Melk I listen to these while I'm at work, while looking at spreadsheets. When I go back and watch the visuals, I find that the Thought Cafe stuff is super-delightful, but I can testify that it is not necessary to get a lot of value from the videos. I second the vote for podcasts; I would love to be able to listen to Crash Course while riding the train or driving across town.

@Cowguruofdeath 7 лет назад

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.

The experimenter gives themselves two cookies, and the girl one cookies, and then asks the girl if thats fair. The girl says no, because she only has one and the experimenter has two. The experimenter then breaks the girl's cookie in half and asks the girl whether its fair now, and she goes "yeah". It's super cute :3

I love his theory however I remember also learning that certain percentage of each category were for each age group and the level matched up with the average. For example, a teen could be at the college level however there is only a 20% chance in comparison to the 70% of the regular teen level. Similarly, there could also be teens on the child's level but only 15%. This concept really helps me understand how people my age think and that even though we have the same education at the same level, we can still process information differently and thus have an easier or more difficult time learning.
