Aims to enforce obedient behaviour in offenders whilst punishing disobedience in hopes the former continues. This is is used in prison as a token economy system.
Prisons are given these tokens for performing desirable behaviour. Tokens are secondary reinforcers as they derive their value from association with a reward.
Phone calls, gym time, food and cigarettes. Vice versa, punishments used as consequences for non-compliance and disobedience leading to withheld privileges.
Behaviours that are reinforced are decided, and everyone who comes in contact with offender must follow selective reinforcement. Some prison officers may reinforce a particular prisoner for working positively. Overseen by officials who monitor programmes effectiveness.
