opperant conditioning Flashcards
what is the basic idea of operant conditiong?
- when people behave in a certain way and are rewarded for it the behaviour is likely to continue and when a behaviour is punished the behaviour is likely to stop
what is meant by positive reinforcement?
- something good is given because of the behaviour which causes the behaviour to be repeated
- e.g. giving someone a hug for doing well in an exam
what is meant by negative reinforcement?
- something bad is taken away due to a behaviour which makes the behaviour continue.
- e.g. someone stops eating unhealthy food, and begins to loose weight and therefore the behaviour is repeated. - weight is being taken away and encourgaging the behaviour to be repeated.
what is meant by punishment?
- something bad being given due to a behaviour which makes the behaviour stop.
- e.g. taking away someones phone because they have broken the rules
what is primary reinforcers?
- the reward is a basic need like food, warmth and sex
what is secondary reinforcement?
- the reward is something you can use to by things for example tokens or money.
contingency
there must not be a time lapse between the reward/punishment and the behaviour. too long a period in between can cause the behaviour to not occur.
contiguity
it must be clear that the behaviour and the reward/punishment depend on each other
what is meant by the word “shaping”?`
- a way of behaviour modification
- where you reinforce small behaviours at first which are brought together to one big behaviour
what did Thorndike find (1911)?
- cat put in a cage with a latch on the door and a piece of salmon outside the cage.
- at first the cats scratched at the cage and tried to reach through to get the salmon
- they then hit the lever by accident
- this is known as trail and error the cat got quicker each time - the first trail took 5 mins and after 10 trials it took 5 secs
- the reinforcement of the food encouraged the cat to repeat the behaviour getting better each time.
what did skinner find?
- conducted a experiment he designed a box where animals such as rats and pigeons could learn behaviours.
- the box punished the animals through electric shocks and rewarded them with food (food was given when the lever was pressed)
- this cause the frequency of behaviour to increase which is reinforcement
what is the point of investigating schedules of reinforcement?
- to see if animals or people learn better if they are rewarded every time they perform a desired behaviour or if the presentation of the reward is varied.
continuous reinforcement ?
- reward is given every time a behaviour is formed a reward is given = slow but steady results
fixed schedule reinforcement?
- related to how many times a behaviour is wanted to be repeated
- reward behaviour every 5 times for example
- slow but effective
