What comprises the three-term contingency in behavior analysis?

The three-term contingency in behavior analysis is articulated through the components of antecedent, behavior, and consequence. This framework is essential for understanding how behaviors are influenced and modified.

The antecedent refers to the environmental stimuli or events that occur before a behavior is exhibited. It sets the stage for what is about to happen, acting as a trigger for the behavior.

The behavior is the observable act or response of an individual. It is the action that takes place following the antecedent.

The consequence follows the behavior and represents the outcome that occurs as a result of the behavior. This can reinforce or deter the future occurrence of that behavior. Depending on whether the consequence is perceived as positive or negative, it can increase or decrease the likelihood of the behavior happening again in similar situations.

This model is foundational in behavior analysis as it helps practitioners understand the relationship between events and actions, making it possible to identify strategies for behavior modification.
