ABSTRACT
After defining the behavior to be changed, the next step is to change the environment that controls the behavior. The behavioral approach assumes that behavior is controlled by antecedents, or cues in the environment that set the stage for the behavior, and by consequences, or reinforcers, that come after the behavior and lead to its recurrence (8). This A-B-C model is shown schematically in Figure 1. For example, the sight offood on a buffet table may lead a person to overeat, or the cue of seeing someone else eating may arouse feelings of hunger. Likewise, the positive consequences that come from the good taste of food or from reduction in feelings of hunger may lead to continued selection of these food items.
