classical conditioning Flashcards
classical conditioning
Refers to a type of learning that occurs through the repeated association of two or more different stimuli. It involves involuntary or automatic responses
Neutral stimulus
The stimulus that originally does not produce any response, but after conditioning becomes the CS
Unconditioned stimulus
Any stimulus that consistently produces a particular, naturally occurring, automatic reflex response.
Unconditioned response
The response which occurs automatically when the UCS is presented.
Conditioned stimulus
The stimulus that is neutral at the start of the conditioning process and does not normally produce the UCR.
Conditioned response
The learned response which is produced by the CS
Acquisition
Acquisition is the overall process where the organism learns to associate the CS + UCS.
Timing is essential, the CS should be presented about half a second before the UCS. This
phase ends when the CS alone produces the CR
Stimulus Generalisation
Stimulus generalisation is the tendency for another stimulus
similar to the original CS to produce a response that is
similar, but not necessarily identical, to the CR.
Extinction
Extinction is the gradual decrease in the strength or rate
of a CR that occurs when the UCS is no longer presented.
Extinction is said to have occurred when a CR no longer
occurs following presentation of the CS.
Spontaneous Recovery
Spontaneous recovery is the reappearance of the CR when the CS is presented, following a
rest period after the CR appears to have been extinguished. Doesn’t always occur. Short.
terminology
Before Conditioning: NS leads to No response
UCS leads to UCR
During Conditioning: NS + UCS leads to UCR
After Conditioning: CS leads to CR
