Chapter 6 Quiz Flashcards
learning
any durable change in behavior
Ivan Pavlov
-“stumbled” across classical conditioning around 1900
-studying “psychic reflexes”
-saliva experiments on dogs
-dogs start responding prior to the meat powder (sounds of preparation)
-realized a neutral stimulus was creation a response
Neutral Stimulus
NS
No Response
NR
Unconditioned Stimulus
UCS
ex: the dog food
Unconditioned Response
UCR
ex: dog salivating
process
repeatedly pair the US with the NS
ex: NS -> the bell
US -> food
UCR -> dog salivating
following repeated pairings…
the NS will begin to elicit the response without the US
conditioned stimulus (CS)…
can only create a conditioned response (CR)
Before Conditioning:
NS -> no response
(the bell)
During Conditioning:
US -> NS
(meat powder) (the bell)
After Conditioning:
US -> UR
(meat powder) (salivating)
l
V
CS
(the bell) -> CR (salivating)
process of condition = acquisition
the initial stage of learning something
process of condition = extinction
the gradual weakening and disappearance of a conditioned response tendency
process of condition = spontaneous recovery
the reappearance of an extinguished response after a period of non-exposure to the conditioned stimulus
process of condition = stimulus generalization
responding to things that are similar to the conditioned stimulus
process of condition = stimulus discrimination
the ability to differentiate between a conditioned stimulus and other stimuli that have not been paired with an unconditioned stimulus
high order conditioning
a conditioned stimulus functions as if it were an unconditioned stimulus
classical conditioning in everyday life:
-conditioned fear and anxiety
–events and interactions can create phobias
-emotional responses as of a result of a certain smell, song, etc
-physiological response (ie immune system)
watson
classical conditioning
skinner
operant conditioning
our behavior is controlled by the…
consequences we receive
operant conditioning
a form of learning in which responses come to be controlled by their consequences
operant responses are said to be…
emitted rather than elicited
primary reinforcers
events that are inherently reinforcing because they satisfy biological needs
ex: food, water
secondary (conditioned) reinforcers
events that acquire reinforcing qualities by being associated with primary reinforcers
ex: paycheck, attention
positive reinforcement
when a response is strengthened because it is followed by the presentation of a rewarding stimulus
negative reinforcement
when a response is strengthened because it is followed by the removal of an aversive (unpleasant) stimulus
punishment
an event following a response weakens the tendency to make that response
positive punishment
something is added
negative punishment
something is taken away
skinner box
a small enclosure in which an animal can make a specific response that is recorded while the consequences of the response are systematically controlled
acquisition
the initial stages of learning new response
shaping
process of repeatedly reinforcing closer and closer approximations to desired reponse
avoidance learning
an organism acquires a response that prevents some aversive stimulation from occurring
contingency theory - Robert Rescorla
-A “type” of classical conditioning
–pairing a US with a CS does not always lead to learning - must have an outcome that is recognizable by the subject
The Law of Effect - Edward Thorndike
responses that create a good effect becomes more likely to occur again, and responses that create a bad effect becomes less likely to occur again
