Learning Flashcards
Classical conditioning
Learning by association. Link them, make it have adapted value
Learning
Relatively permanent change in behavior as a function of experience
Ivan Pavlov
Digestion in dogs
Food created salvation
Focused on classical conditioning
Unconditioned stimulus
Stimulus that causes a response without prior learning
Ex: food automatically causes salvation
Unconditioned response UCR
Triggered automatically by the unconditioned stimulus
Ex salvation
Conditioned stimulus
Initially neutral stimulus that triggers a learned response
Whistle every time food arrives
Conditioned response
Learned response
Ex: salvation in response to a whistle alone
Examples
Ucs- cigarette burn
Ucr- pull away
Cs- lights off
Cr- light off hand withdrawn
Ucs- chemo
Ucr- vomiting and nausea
Cs- waiting room
Cr- vomit at sight of waiting room
Extinction
Elimination of a behavior because association is no longer there
Spontaneous recovery
Behavior may occur again in the future
Occurs weaker than before
Stimulus generalization
Stimuli similar to the conditioned stimulus may trigger to the conditioned response
Ex: Orange and lemon
Discrimination
Learn to tell difference between warning stimuli from neutral ones.
Higher order conditioning
Neutral stimulus becomes conditioned stimulus after being paired with an already established conditioned stimulus.
Ex: flinch at smell of lemon and purring sound. Even without sound you flinch
Shaping
Gradually reinforce behavior as if approximates desired response
Ex: treats along the way
Chaining
Reinforcers are used to develop a sequence, chain of behaviors
Ex: roll right, roll left, sit at attention
