View full lesson: http://ed.ted.com/lessons/the-difference-between-classical-and-operant-conditioning-peggy-andover Why is it that humans react to stimuli with certain behaviors? Can behaviors change in response to consequences? Peggy Andover explains how the brain can associate unrelated stimuli and responses, proved by Ivan Pavlov's famous 1890 experiments, and how reinforcement and punishment can result in changed behavior. Lesson by Peggy Andover, animation by Alan Foreman.

What do you bet that for the rest of his life, whenever he hears a bell, Pavlov thought about feeding the dogs.
This looks and feels like USSR propaganda lol
I really like this animation style, is there a specific name for this style apart from USSR propaganda?
“Tell me, I won’t get mad, I promise” Classical conditioning we all have
Ahhh, "We need to talk" is classical conditioning, then....
Last day of study for the exam tomorrow. Definitely easier to understand compared to my notes.
Is it ironic that after all these lectures on classical conditioning mentioning bells, I now reflexively think about conditioning every-time I hear a bell?
Finally someone who can explain classical conditioning. I've had two different teachers who couldn't figure out how the various types of stimuli are labeled.
The dogs in Pavolv's experiment did not "learn to EXPECT food when they heard a bell." Their conditioned response was not the result of a conscious expectation. That's the whole point of understanding Classical Conditioning. Their nervous systems became PRIMED by the sound of the bell through repeated pairing of this previously neutral stimulus with a naturally occurring unconditioned stimulus (food). Even if the dogs somehow lost the memory of their training through some form of amnesia, they likely would still respond to the bell by salivating. We know this is true with many humans who suffer brain damage, for instance. Even though they don't recall their past experiences, their conditioned responses remain, and they react to various stimuli as their training dictates. To say that Pavlov's dogs EXPECTED something is to suggest that Classical Conditioning is a conscious process. Dogs (and other animals) do not salivate as a purposeful act. Salivation is a nonconscious behavior. So, even if they learned to EXPECT food when they heard a bell (a conscious act), they shouldn't respond by salivating (because we don't activate our salivary glands on purpose). The fact that they DID salivate in response to the bell shows that the connection is being made in their nervous systems, not as a conscious process.
Operant conditioning - the music at the end credits of a video
Trick question: if this video reminds you of communist propaganda was it positive or negative reinforcement or positive or negative punishment? What is the stimulus?
Little piece of trivia: Classical conditioning is what usually teaches us fears. And it can be used to reinforce behavior as well, but it's not as effective as operant conditioning.
Her voice is so soothing. I want a teacher with this voice. :) And the lesson was great too.
*In summary* _Classical Conditioning_ - Stimulus then the response Ivan Pavlov Experiment - Ringing the bell then the dog will salivate _Operant Conditioning_ - Positive and Negative Reinforcement Positive reinforcement - Reward because of doing something great Negative reinforcement - No more punishment or additional work because of doing something great
OMG! This helped so much more then my Psych notes. Thank you for this video! I have my final tomorrow.
I love the way you married the narration and animations! The video was very helpful and I look forward to seeing you bring the difference between classical and operant conditioning.
This came up after I watched a vid about Kafka. The graphics are (mwah, chef's kiss) perfecto
I think this method of conditioning begins at birth, as we know, as infants if they cry their needs are met, if they laugh and giggle they get love and attention, if they mis behave they know they will be punished. I used these examples of human behavior so that tells us that it didn't begin with Pavlov, he just named the conditioning and made humanity aware of this.
good intro video however you didnt explain the negative reinforcement part... as well as the positive & negative punishment....
Best video! I have a final tomorrow, thank you very much! :)
