Institutions compile a list of desirable behaviours so when offenders act this was they receive a token which they can cash in for rewards - Token economy
Some studies show improvements but when the rewards stop eg. when leaving prison the offenders stop behaviour desirably
Offenders return to crime slower if they have gone through token economy
Token economies make prisoners more manageable when in prisons
Positive reinforcement: when a behaviour is more likely to occur to gain a positive reward
Negative reinforcement: when a behaviour is more likely to occur to avoid a negative punishment
