Ch. 8 Flashcards
Ivan Pavlov
Russian physiologist was studying the digestive system of dogs. Came up with CLASSICAL CONDITIONING.
Learning
A relatively permanent change in behavior as a result of experience.
Classical conditioning
Type of learning in which an organism comes to associate stimuli. A neutral stimulus that signals an unconditioned stimulus (US) begins to produce a response that anticipates and prepares for the unconditioned stimulus.
Classical conditioning parts
Unconditioned stimulus, unconditioned response, neutral stimulus, conditioned stimulus, conditioned response.
Unconditioned stimulus (US)
Produces a response without prior learning.
Unconditioned response (UR)
Unlearned response that is automatically associated with the Unconditioned stimulus.
Neutral stimulus (NS)
Stimulus that does not elicit any response. Same as conditioned stimulus.
Conditioned stimulus (CS)
Previously the Neutral stimulus that elicits the conditioned response after being paired with the Unconditioned stimulus.same as neutral stimulus.
Conditioned response (CR)
Learned response to the conditioned stimulus.
Ex. My brothers chased me around with snakes when I was little. Now I am afraid if snakes.
US: brother chasing you UR: scared, or fear NS: snakes CS: snakes CR: fear
Ex. A little girl is stung by a bee while smelling a flower. Now she is afraid of flowers.
US: being stung UR: fear, NS: flower CS: flower CR: fear
Ex. I fall asleep while studying psychology. Now every time I look at my psychology book, I yawn.
US: studying UR: fall asleep NS: psych book CS: psych book CR: yawning, falling asleep
Ex. I was in a car accident, now everytime I drive, I am very nervous and tense.
US: accident UR: nervous and tense NS: driving CS: driving CR: nervous and tense
Ex. My boyfriend works at Burger King, and every time I visit him he gives me a kiss. Now I’m sexually aroused when I smell onion breath.
US: boyfriends kiss UR: arousal NS: onion breath CS: onion breath CR: arousal
A crying baby wants to eat. A nursing mother finds that her milk lets down every time she hears her baby cry even when it’s not time.
US: feeding time UR: milk lets down NS: crying baby CS: crying baby CR: milk lets down
Acquisition
The pairing of the unconditioned stimulus and the neutral stimulus so the neutral stimulus comes to elicit the conditioned response. Often in classical conditioning the pairing between the US and NS must occur several times before it comes to elicit the CR.
Taste aversion
Acquisition only takes one time because the response is so strong.
Protection from our environment.
Generalization
Tendency of a new stimulus that is similar to the original stimulus to elicit a response that is similar to the CR.
little Alberts generalized fear.
(Because of an experience with golden retrievers you’re afraid of all dogs in general.)
Discrimination
Learning to respond to certain stimuli and not others.
Afraid of just golden retrievers and not dogs in general.
A golden retriever jumps up one little boy. Now every time he sees a dog, he whimpers.
US: jumping dog UR: whimpers NS: dog CS: dog CR: whimpers Generalizing stimulus: all dogs Discriminating stimulus: golden retrievers
Extinction
The weakening of the CR in the absence of the US.
Spontaneous recovery
The CR can appear again without further conditioning.
