A(n) is the set of rules regarding reinforcement contingencies, such as which behaviors will be reinforced, which consequences will follow those behaviors, and the schedule by which those consequences will be delivered.

A Schedule Reinforcement is  an offshoot idea under operant conditioning (by Burrhus Frederick Skinner) in which it believes that using positive and negative reinforcements will increase or diminish the likelihood of such behavior. This is composed of Fixed-ratio, Variable-ratio, fixed-interval and variable-interval ratios.
