Models to explain learning Flashcards
Classical conditioning
A type of learning that occurs through repeated association of two or more different stimuli.
Neutral stimulus (NS)
An object or event that does not produce a response, however later becomes the CS due to association with UCS.
Conditioned stimulus (CS)
Stimulus that produces the learned response - was originally the NS.
Unconditioned stimulus (UCS)
Stimulus that produces a naturally occurring, automatic response.
Conditioned response (CR)
The learned response to the CS.
Unconditioned response (UCR)
The response that automatically occurs when the UCS is presented.
What are the 3 phases of conditioning?
Phase 1: Before conditioning
Phase 2: During conditioning
Phase 3: After conditioning
Phase 1: Before conditioning
the NS produces no response, and the UCS produces the UCR.
Phase 2: During conditioning
NS is repeatedly paired with UCS to produce UCR.
Phase 3: After conditioning
NS becomes the CS, the CS produces the CR.
Classical conditioning - Stimulus generalisation
A stimulus that is similar to the CS producing a response that is similar to the CR.
Classical conditioning - Stimulus discriminiation
When a person response to the CS only, and not to any stimulus that is similar to the CS.
Classical conditioning - extinction
The gradual decrease in the strength of the CR that occurs when the UCS is no longer presented.
Classical conditioning - spontaneous recovery
The reappearance of the CR when the CS is presented following a rest period after extinction.
Little Albert experiment
- who conducted it
- NS, UCS, UCR, CS, CR
John B. Watson
NS = white rat
UCS = loud noise
UCR = crying
CS = white rat
CR = crying
Ethical implications of Little Albert experiment
Informed consent - Alberts mother may not have known that her son was being used to condition a fear response.
Withdrawal rights - the experimenters made no attempt to end the experiment after little albert showed signs of severe stress and anxiety.
Psychological harm - Albert was most likely psychologically traumatised.
