Learning Flashcards
(38 cards)
underlying machinery that makes behavior happen
physical machinery of the CNS
What isn’t learning
- fatigue
- change in stimulus conditions
- alteration in physiological or motivational state
- maturation
habituation
a decrease in response as a consequence of repeated exposure to stimulus
stimulus- stays constant
response- decreases
Which response is learned and which is innate in habituation
initial response is innate- not learned
decrease in response is learned
dishabituation
habituated response is restored by exposure to strong extraneous stimuli paired with stimulus to which animal has habituated
sensitization
increase in responsiveness produced by repeated stimulation
generally temporary effects
duration determined by intensity of sensitizing stimulus
stimulus- constant
response- increased
Classical Conditioning
aka Pavlovian Conditioning
simplest mechanism whereby an organism learns about relationships between stimuli and comes to alter its behavior accordingly
association type learning
unconditioned stimulus
stimulus that elicits a particular response without necessity of prior training
unconditioned response
response that occurs to a stimulus without the necessity of prior training
conditioned stimulus
stimulus that does not elicit a particular response initially but comes to do so as a result of being associated with a US
conditioned response
response that comes to be made to the CS as a result of classical conditioning
called conditioned response when it is elicited by the conditioned stimulus
extinction
if animal is repeatedly exposed to CS without further pairing with the US then the animal’s response to CS will eventually cease
extinction vs habituation
extinction: loss of learned response
habituation: loss of innate response
What is learning?
enduring change in mechanisms of behavior involving specific stimuli and/or responses that result from prior experience with similar stimuli and responses
Operant Conditioning
Also called instrumental conditioning
behavior is affected by its consequences
- pleasant consequences= likely to be repeated behavior
- unpleasant consequences= less likely to be repeated
eliciting stimulus
gives the animal information about the immediate consequences of a given behavior
appetitive stimulus
pleasant event
aversive stimulus
an unpleasant event
reinforcement
the probability that the behavior will recur is increased
punishment
the probability that the behavior will recur is decreased
positive operant conditioning term
the controlling stimulus is present or occurs as a consequence of the response occurring
response produces the stimulus
appetitive or aversive
negative operative conditioning term
controlling stimulus is absent or removed as a consequence of the response occurring
response eliminates or prevents the occurrence of the stimulus
-appetitive or aversive
operant conditioning: positive and negative reinforcement
positive reinforcement: probability that the behavior will occur increases as consequence of the CS being present or occurring immediately subsequent to behavior
negative reinforcement: the probability that the behavior will recur increase as a consequence of the controlling stimulus being absent or removed if the behavior occurs
prompting and fading
initially getting animal to do desired behavior
-gently guide the animal into position while giving an eliciting stimulus such as sit
fading- once desired behavior is attained- give reinforcer and with repetition gradually fad the intensity of the prompt
