WEEK 2 Flashcards
Define ‘Classical Conditioning’
Classical conditioning involves the learning of associations between two otherwise unrelated stimuli, e.g. the ringing of a bell and delivery of food. Once the association is established, a conditioned response will occur in response to a previously neutral stimulus, e.g. a dog salivating when a bell is rung.
This form of conditioning was first noted by Ivan Pavlov
Define ‘Operant conditioning’
Operant conditioning occurs when an organism learns that a particular behaviour will produce a consequence within their environment. If the behaviour produces a positive outcome, the behaviour is likely to increase in frequency; whereas if the behaviour produces a negative outcome, it is likely to decrease in frequency. Outcomes that increase the frequency of a behaviour are called reinforcers.
Define ‘habituation’
The process of adapting to stimuli that do not change
e.g. wearing the same perfume each day for several weeks, to the point where you don’t notice the smell
Define ‘opponent process theory’
Conditioned responses to stimuli associated with administration of a drug tends to elicit responses that counteract the effects of the drug. It posits that emotional experiences are often followed by opposing emotional reactions, leading to a gradual return to emotional equilibrium.
E.g. experiencing a high level of excitement on a roller coaster, then feelings of relaxation and relief after the ride levels out.
For example: Stimuli associated with administration of a drug can elicit conditioned withdrawal responses
Define ‘sensitisation’
Exposure to a strong stimulus will reinitiate response to a habituated cue
For example: Every sound we hear will keep us awake if we have just watched a movie marathon of horror films
Define ‘unconditioned stimulus’
A stimulus that elicits a response without conditioning
E.g. Pollen from grass and flowers, causing you to sneeze
Define ‘conditioned response’ (CR)
The response that the conditioned stimulus elicits
Define ‘conditioned stimulus’ (CS)
the originally neutral stimulus that, through pairing with the unconditioned stimulus, comes to elicit a conditioned
response
E.G. Kids leaving a classroom when they hear the bell
Define ‘unconditioned response’
The automatic or unlearned response to stimuli
Define ‘extinction’
The gradual disappearance of a conditioned response or operant behaviour when a conditioned stimulus is no longer followed by an unconditioned stimulus
For example: A child visits the doctor’s office several times for a check-up but does not receive an injection. Fear may eventually cease
Define ‘reconditioning’
The quick relearning of a conditioned response following extinction
Define ‘spontaneous recovery’
The reappearance of a conditioned response after extinction and without further pairings of the conditioned and unconditioned stimuli
Define ‘stimulus generalisation’
a phenomenon in which a conditioned response is elicited by stimuli that are similar but not identical to the conditioned stimulus
For example: A child fears doctors offices and places that smell like them
Define ‘stimulus descrimination’
A process through which individuals learn to differentiate among similar stimuli and respond appropriately to each one
For example: A child learns that his mother’s doctor’s office is not associated with the UCS
Define ‘higher-order conditioning’
a phenomenon in which a conditioned stimulus acts as an unconditioned stimulus, creating conditioned stimuli out of events associated with it
e.g. PTSD
