Which operation is used to weaken a behavior's effectiveness?

The operation used to weaken a behavior's effectiveness is known as an abolishing operation. This type of operation diminishes the reinforcing effectiveness of a stimulus, object, or event. When an abolishing operation is in effect, the value of a reinforcer decreases, which in turn reduces the likelihood of the behavior that was previously reinforced by that stimulus.

For example, if an individual has a strong desire for food when they are hungry but their hunger is satisfied, the effectiveness of food as a reinforcer becomes less potent, leading to a decrease in behaviors associated with seeking food. This principle is essential in understanding how motivations and behaviors can be modified in a behavioral context.

In contrast, establishing operations increase the effectiveness of a reinforcer, thereby strengthening the associated behaviors. Motivating operations include both abolishing and establishing operations, and involve all conditions that affect the momentary effectiveness of a reinforcer but do not solely focus on weakening. Behavioral operation is not a standard term used in this context. Understanding these concepts is fundamental to applying behavior analysis effectively.
