Final answer:
Successive approximations refers to the behavior change methodology called shaping, where small, incremental steps towards the target behavior are rewarded.
Step-by-step explanation:
Successive approximations is a term used in the behavior change methodology called shaping. In shaping, the target behavior is achieved by rewarding small, incremental steps or approximations towards the desired behavior. This helps the organism to learn and develop complex behaviors by reinforcing each successive approximation.
