This document discusses token economies, which use conditioned reinforcers or "tokens" that can be saved and later exchanged for backup reinforcers. Token economies bridge the gap between a behavior and its reinforcement by allowing tokens to be earned immediately but redeemed later. Steps in developing a token economy include choosing target behaviors, baseline data collection, selecting a variety of backup reinforcers, choosing tokens that are not easily counterfeited, record keeping, and programming for generalization beyond the token system. Token economies can be used to modify behavior in various settings like hospitals, institutions, and work environments.
