How to Train a Brain: Crash Course Psychology #11

Spread The Viralist



I’m sure you’ve heard of Pavlov’s Bell, but what was Ivan Pavlov up to, exactly? And how are our brains trained? And what is a “Skinner Box”? All those questions and more are answered in today’s Crash Course Psychology, in which Hank talks about some of the aspects of learning.

  1. it's funny how i end up being so fascinated by human psychology
    to the point that i may kind of start seeing others as test subjects….

    but fortunately my ideals(Islamic teachings) set boundaries for
    how far i can go with my doings.
    Fortunately.

    did Hank or the crash course team link a source that I failed to find somewhere?

    because a quick google search revealed to me that "Little Albert" did not die soon after the experiment but in fact lived to old age.

    if anyone has a source that strongly proved otherwise, please share 😀
    thanks!

  3. I came here because of a bell notification that their was a new video. (no really, I'm like you cramming for a Psych exam) and I like being rewarded with good grades…

    I watched because I love the process of acquiring, through experience, new and relatively enduring information or behaviors through visuals…

    I have become growing more and more excited during every post and bell notification, and I get discouraged when my phone goes off and isn't notifying me of new videos…

    That moment when you realize you're living Inception and you're really just one of Pavlov's dogs in the flesh.

  4. I could see this video both informative and a great example of conditioning. YouTube videos tend to have ads. We tend to expect a skip ad button to click. This video does not have an ad, an example of operant conditioning.

  5. For my psych class assignment, I have to leave a comment, I sure hope you see it professor.
    I have one thought on classical conditioning, if the food makes the dog drool, and the dog can be conditioned to drool from the bell, then does that mean that the drool from the dog may caused because the dog is actually hungry to eat the food? Or is the dog just drooling because it was conditioned to from the food, did the dog drool when it was first presented with the meat powder food? I guess basically what I'm curious is does the original stimulus itself become a condition at some point? Another such as negative reinforcement (where a person has to do something to remove something that negatively effects them) is also a curious case. In my personal experience, having to do something to avoid discomfort is not very rewarding because it implies I must experience something negative whenever I don't fulfill desired behavior and most of the time, I didn't wanna do it anyway

  6. Another example of classical conditioning in humans I can think of: People who reframe from eating meat can sometimes get discussed at the concept that people eat meat. This sometimes makes it so that when they withness somebody eating meat, they get discussed. After a while, they get discussed at the concept of coming near somewhere that serves meat.

  7. Dear Crash Course,
    Thank you for making this quick, thoroughly informative, and entertaining video about the crazy world of classical and operant conditioning. Now I feel much more prepared for my exam!

  8. I have a Pavlov's cat. She brings one of her toys to one of a few places and we give her a treat. She'll sometimes meow excitedly when one of us bends over (since we bend over to pick up the toy)

  9. Psych CrashCoursers: Are you watching this through the Learning Playlist? What do you think of that format? I really appreciate the features of the Learning Playlist that these have been put it. It is easier for me to pick up where I left off and I avoid the distractions of the recommendations sidebar.
