To establish the function of operant behavior, one typically examines the "four-term contingency": first by identifying the motivating operations (EO or AO), then identifying the antecedent or trigger of the behavior, identifying the behavior itself as it has been operationalized, and identifying the consequence of the behavior which continues ...
Operant behavior is voluntary behavior that is sensitive to, or controlled by its consequences. Specifically, operant conditioning refers to the three-term contingency that uses stimulus control. In the three-term contingency, first, a discriminative stimulus signals to the subject that reinforcement (or, less commonly, punishment) is available.
The three-term contingency already includes antecedent stimulus topographies, and the previous version had already incorporated discussion of motivating operations. The use of a "four-term contingency" as described in behavioral research doesn't even match the role of motivating operations and actually means something different.
Though initially operant behavior is emitted without an identified reference to a particular stimulus, during operant conditioning operants come under the control of stimuli that are present when behavior is reinforced. Such stimuli are called "discriminative stimuli." A so-called "three-term contingency" is the result. That is, discriminative ...
Central to operant conditioning is the use of a Three-Term Contingency (Discriminative Stimulus, Response, Reinforcing Stimulus) to describe functional relationships in the control of behavior. Discriminative stimulus (S D) is a cue or stimulus context that sets the occasion for a response. For example, food on a plate sets the occasion for eating.
The three-term contingency (also known as the ABC contingency) is a psychological model describing operant conditioning in three terms consisting of a behavior, its consequence, and the environmental context, as applied in contingency management. The three-term contingency was first defined by B. F. Skinner in the early 1950s. [1]
A solid backup quarterback only seems like a luxury until the starter goes down. So we ranked all 32 NFL teams on their No. 2 options and beyond.
Behavior is a function of the antecedent and consequences that make up the three-term contingency. Functional assessment is the process of gathering information about the antecedent stimuli and consequences functional to the problem behavior.
