Learning Flashcards
Ivan Pavlov
Russian Physiologist
Did research on digestive system of dogs
-Reflex
Unlearned, involuntary response
Stimulus
Any object, event, or experience that causes a response
Food = Stimulus
Response
The reaction of an organism
Salivation = response
Pavlov Research
learned associations were formed by events in the organism’s environment.
Pavlov’s Classical Conditioning
Learning to elicit an involuntary response to a neutral stimulus other than the original natural stimulus that normally produces the response
Unconditioned Stimulus (UCS)
Evokes an unconditioned response. It is the original, naturally occurring stimulus that leads to the involuntary response (Food=Salivate) Unconditioned means unlearned.
Unconditioned Response (UCR)
An unlearned response to an UCS (Salivation before conditioning) It is automatic and involuntary. Occurs because of genetic “wiring” in the nervous system (Salivating Food)
Neural Stimulus (NS)
Does not evoke a response (tone)
Conditioned Stimulus (CS)
A neutral stimulus that now acquires the capacity to evoke a conditioned response (tone after conditioning)
Conditioned Response (CR)
A learned response to a CS (Salivation after conditioning)
Trial
Pairing of UCS and CS
Acquisition
Initial stage in learning
Stimulus Generalization
When an organism responds in the same way to new stimuli that are similar to the original stimulus
Stimulus Discrimination
when an organism does not respond in the same way to new stimuli that are similar to the original stimulus
Extinction
The gradual weakening and disappearance of a conditioned response
Spontaneous Recovery
Reappearance of an extinguished response after a period of non exposure to the conditioned stimulus
Vicarious Conditioning
Classical conditioning of an involuntary response or emotion by watching the reaction of another person
Operant Conditioning
Associating behaviors and consequences
Operant conditioning deals with the learning of active, voluntary behaviors that are shaped and maintained by their consequences
Thorndike’s law of effect
An action followed by a pleasurable consequence will tend to be repeated
An action followed by an unpleasant consequence will not be repeated
B.F. Skinner
Behaviorism -Voluntary behavior Operant Behavior Any behavior that is voluntary Animals and humans operate in the world to get something or avoid something Operant Conditioning Learning of operant behavior
Reinforcement
Means to “Strengthen”
Key to learning
Primary Reinforcers
Satisfy biological needs
Secondary Reinforcers
Conditioned Reinforcement
Positive Reinforcement
Response followed by rewarding stimulus
