The Operant Model
The basic concepts of the operant model are reinforcement and punishment: the consequences of a response determine the probability of the future occurrence of that response. As shown in the flowchart (p. 000), the basic assessment question is: Are the consequences of the problem behaviors initiating or maintaining those behaviors? Those consequences that increase the probability of a response are called positive reinforcers, and those that decrease the probability of a response are called punishers. To employ the operant model means to be selectively attuned to the consequences of the behavior of interest.
