6.1- Classical Conditioning Flashcards
learning
a process by which behaviour or knowledge changes as a result of experiences [rewards + punishments]
classical conditioning
a form of associative learning in which an organism learns to associate a neutral stimulus (sound) with a biologically relevant stimulus (food) which results in a change in the previously neutral stimulus
stimulus
a external event or cue that elicits a perceptual response [food, water, sex]
unconditioned stimulus (US)
a stimulus that elicits a reflexive response without learning (the food you smell that makes you hungry)
Unconditioned response (UR)
a reflexive, unlearned reaction to a unconditioned stimulus (getting hungry after smelling food)
conditioned stimulus (CS)
a once neutral stimulus that later elicits a conditioned response because it has a history of being paired with an un-conditioned stimulus (the ‘clicker’ from pavlovs dogs)
Conditioned response (CR)
the learned response that occurs to the conditioned stimulus (dog salivating from clicker)
EX: [Associating a doctors office with pain from getting a needle in the past] What is the ‘US’?
the needle
EX: [Associating a doctors office with pain from getting a needle in the past] What is the ‘UR’?
the pain caused from the needle
EX: [Associating a doctors office with pain from getting a needle in the past] What is the ‘CS’?
sights and sounds at doctors office over time
EX: [Associating a doctors office with pain from getting a needle in the past] What is the ‘CR’?
triggered fear of the doctors office
Acquisition
the initial phase of learning in which a response is established [US paired with UR]
Extinction
the reduction of a conditioned response when a conditioned stimulus and unconditioned stimulus no longer occur together [when the routine is off or less]
Spontaneous Recover
the reoccurrence of a previously extinguished conditioned response, typically after some time as passed since extinction
generalization
a process in which a response that originally occurred for a specific stimulus also occurs for different, similar, stimuli [reaction from a sound similar to the ‘clicker’]
