psychology test 2 (pt.3) Flashcards
define classical conditioning and what experiment it correlates to.
- created by ivan pavlov
- Classical conditioning is earning in which an association is formed between one stimulus and another.
- A stimulus = any event or object in the environment
- experiment where you are conditioning the dog with the bell and food rewards.
what is a neutral stimulus?
A stimulus that does not produce a response when presented.
what is a Unconditioned stimulus? and give examples.
A stimulus that automatically produces a response (without learning)
Ex: food, light in the eye, loud noises
what is a unconditioned response and give examples.
Automatic unlearned response made to the US. Ex: salivation, pupil contraction, startle
what is a conditioned stimulus?
previously NS that, after repeated pairings with an US, produces same response that follows the US
what is a conditioned response
the learned response made to the CS
what are some terms that are related to classical conditioning?
- Extinction
- spontaneous recovery
- Generalisation
- discrimination
explain Extinction (classical conditioning)
the weakening (and eventual disappearance) of a learned response that occurs when CS is repeatedly presented without US
explain spontaneous recover (classical conditioning)
sometimes occurs when, after extinction, the CS is presented and the CR reappears.
explain generalisation (classical conditioning)
occurs when a stimulus, similar to the CS, elicits the CR
explain discrimination (classical conditioning)
has occurred when the CR is made only to the CS and not to similar stimuli.
Explain the experiment conditioning little Albert
- 1919: John Watson conditioned baby Albert to fear a white rat.
- Generalisation: little Albert also learned to fear other things that resembled the white rat (eg. a rabbit).
–> Fear can be conditioned
what are the factors that influence classical conditioning? the CR is stronger when:
- More CS - US pairings
- US more intense
- CS reliably predicts US
- CS must precede the US
what are some examples of classical conditioning in real life?
- Taste aversion
- Fears and phobias (animals, dentists)
- Commercials
–>Ads associate neutral products (eg. car) with pleasant stimuli (eg. pretty girls) - Sexual arousal and clothing
–>Read the story about rats in jackets
who is related to operant conditioning?
B.F. Skinner
explain what operant conditioning is
- Learning in which consequences of behaviour modify a future response:
- Rewards increase a response
- Punishment decreases it
- Conditioning of voluntary responses
(Operant conditioning) what is the reinforcer? and give examples
- anything that follows a response that increases the chances the response will occur again.
–>Food, sex, $$, social approval
(operant conditioning) what is shaping? and give examples
- Reinforcing or rewarding successive approximations of the desired response.
—->Eg. training animals
explain the skinner box lab
Operant conditioning apparatus: eg. a box with a lever/bar that the animal presses to get a reward.
explain extinction (operant cond.)
occurs in operant conditioning when reinforcement is withheld.
explain generalization (operant cond.)
response to similar stimuli
explain discrimination (operant cond.)
animal responds to one reinforcer but not other similar ones
