3.2.3-6 models to explain learning Flashcards
classical conditioning
form of learning that occurs through the repeated association of two (or more) different stimuli
classical conditioning: neural stimulus
impartial stimulus that causes no response
classical conditioning: unconditioned stimulus
any stimulus that consistently produces a particular, naturally occurring automatic response
classical conditioning: unconditioned response
response that occurs automatically when the UCS is presented
classical conditioning: conditioned stimulus
stimulus that was neutral at the start of conditioning and does not normally produce an unconditioned response
classical conditioning: conditioned response
learned response that is produced by the conditioned stimulus
classical conditioning: acquisition
overall process during which the organism learns to associate the two events
classical conditioning: extinction
gradual decrease in the strength or rate of a CR that occurs when the UCS is no longer presented.
the CR no longer follows the presentation of the CS
classical conditioning: spontaneous recovery
reappearing of the CR when the CS is presented, following a rest period, after the CR appears to have been extinguished
classical conditioning: spontaneous generalisation
tendency for another stimulus that is similar to the original CS to produce a response that is similar
classical conditioning: spontaneous discrimination
when the person or animal responds to the CS only, but not any other stimuli that is similar to the CS
operant conditioning
type of learning for which the consequences of a behaviour determine the likelihood that it will be performed again in the future
operant
response that occurs and acts on the environment to produce some kind of effect
three-phase model: antecedent
any stimulus that triggers an action.
what causes the behaviour?
three-phase model: behaviour
observable voluntary actions by the organism.
the response by the learner
three-phase model: consequence
any stimulus that makes the behaviour more likely to re-occur.
what reinforcement or punishment do they receive for their behaviour
operant conditioning: acquisition
establishment of a response through reinforcement
operant conditioning: extinction
gradual decrease in the strength or rate of a CR, following a consistent non-reinforcement of the response
operant conditioning: spontaneous recovery
organism will once again show the response in the absence of reinforcement, after it appears the response has been extinguished
operant conditioning: spontaneous generalisation
correct response is made to another stimulus that is similar to the stimulus that was present when the conditioned response was reinforced
operant conditioning: spontaneous discrimination
occurs when an organism makes a correct response to a stimulus and is reinforced but doesn’t respond to any other stimulus
reinforcement
applying a positive stimulus or removing a negative stimulus to strengthen the likelihood of a particular response that it follows
positive reinforcement
occurs from giving or applying a positive reinforcer after the desired response has been made.
e.g. receiving gold star
negative reinforcement
the removal or avoidance of an unpleasant stimulus.
increase likelihood of response happening again.
e.g. putting seatbelt to stop buzzing
