learning Flashcards
learning
relatively lasting change in behaviour as a result of experience
classical conditioning
a learning process in which association is made between a previously neutral stimulus and a stimulus that naturally evokes a response
IVAN PAVLOV AND HIS DOGS
UNCONDITIONED STIMULUS: the stimulus that naturally evokes a response without the need to learn a new behaviour (meat)
UNCONDITIONED RESPONSE: the natural response to the unconditioned stimulus (salivation at sight of meat)
CONDITIONED STIMULUS: the stimulus that previously had no response but after being associated with the unconditioned stimulus eventually triggers a conditioned response ( the bell)
CONDITIONED RESPONSE: the learned response to a previously neutral stimulus
extinction (CC)
after not being conditioned for a long period of time, the conditioned response stops
spontaneous recovery (CC)
even after extinction, the conditioned response may come back, even years later
stimulus generalisation (CC)
a conditioned being can associate the conditioned stimulus with other stimuli (eg a child that is afraid of one dog can become afraid of all dogs and even all animals)
discrimination (CC)
a conditioned being can differentiate between a conditioned stimulus with other stimuli (eg children can associate feeling hungry with the sound of the school bell, but not the sound of other bells)
contiguity (CC)
the less time passes between seeing the conditioned stimulus and the conditioned response happening, the more likely the being is to associate the stimulus to the response
conditioned stimulus and unconditioned stimulus scheduling
delayed/forward conditioning: where the bell is presented first and the food is presented AFTERWARDS
trace conditioning: the bell is presented, and then the food is (after a short break)
simultaneous conditioning: the bell and food are presented at the same time and continue for the same amount of time
backward conditioning: the food is presented first, then the bell
higher/second order conditioning
where a new stimulus paired with the conditioned stimulus creates a conditioned response (eg the bell is also paired with a flash of light, and then light without the bell also causes salication)
operant conditioning
encouraging a change in behaviour with reward or punishment. makes the being choose between a voluntary behavior and consequence
THORNDIKE’S LAW OF EFFECT
Thorndike made cats open doors in a box through mechanisms. the cats would be rewarded with food if successful. the cats would eventually open the doors faster to get the reward
Thorndike stated that any behaviour thats rewarded is likely to be repeated, and any punished behaviour is likely to cease
BF SKINNER’S POS/NEG REINFORCEMENT
BF Skinner put rats in boxes and if they pressed a lever theyd be given food/electric shocked. the former encouraged pressing the lever, the latter discouraged it
primary reinforcer
a source of motivation to do something that is learned naturally through evolution (eating, sleeping, drinking)
secondary reinforcer
a source of motivation that is learned eg money
