chapter 4 - reinforcement Flashcards
define reinforcement (3)
- occurrence of a behaviour
- followed by an immediate CONSEQUENCE
- behaviour is MORE likely to occur in the future
how does positive reinforcement differ from negative reinforcement
positive: occurrence of behaviour is followed by the ADDITION of a stimulus (or event)
negative: occurrence of behaviour is followed by the REMOVAL (or AVOIDANCE) of an aversive stimulus
What are two types of negative reinforcement
escape: behaviour terminates aversive stimulus (already present)
avoidance: behaviour PREVENTS the occurrence of an aversive stimulus
socially-mediated reinforcement is through…
actions of someone else
eg asking someone to get the chips for you
automatic reinforcement is through…
direct contact with the environment
eg. getting up and grabbing the bag of chips yourself
what are unconditioned reinforcers?
- biologically determined
give examples of primary reinforcers (what’s the other name for it)
unconditioned reinforcers:
food, water, sex, heat, escape from extreme stimulation
what are conditioned reinforcers?
- neutral stimulus paired with established reinforcer
- the established reinforcer could be conditioned or unconditioned
what are some examples of secondary reinforcers (whats the other name?)
conditioned reinforcers:
- sight, sound, scent from family
- attention, praise
- types of toys, tv shows, clothes
- grades, accomplishments
- money
what are generalized conditioned reinforcers? examples?
- they are paired with a wide variety of other reinforcers
- eg: money, praise, tokens
what are the factors that influence reinforcement? (5)
- immediacy
- contingency
- individual differences
- magnitude (or amount)
- motivating operations
- establishing operations (EO)
- abolishing operations (AO)
what are some schedules of reinforcement?
continuous (crf)
intermittent
fixed ratio / variable ratio
fixed interval / variable interval
concurrent schedules
what is a continuous reinforcement schedule (crf)
every occurrence of a response is reinforced
what is an intermittent reinforcement schedule
some occurrences of a response are reinforced
what is a fixed ratio schedule? what are some effects of it
reinforcer given after specific number of responses
- produces high rates of responding
- PAUSE after reinforcement
eg: Pablo gets a token from his supervisor after every 20 parts that he packages
what is a variable ratio schedule? what are some effects of it
reinforcer delivered after an average number of responses
- produces high and steady rates of responding
- no pause after reinforcement
eg slot machine will hit the jackpot after an avg of x amount of attempts
what is a fixed interval schedule of reinforcement? effects?
reinforcer for FIRST RESPONSE after a given amount of time
- produces low rates of responding, with on-off pattern
- response rates increase near end of interval
eg. every 30 minutes Pablo’s supervisor comes around and gives him a token for the first part Pablo packages
what is a variable interval schedule of reinforcement?
reinforcer for FIRST RESPONSE after an average interval of time
- produces steady, low-moderate rates of responding
- no on/off pattern
a ______ behaviour is strengthened through the process of reinforcement
operant
right after a person has had a large amount of a reinforcer, will the reinforcer be more or less potent at that time?
less
