Behavioral economics has applied psychology concepts related to cognitive analysis, which gives little importance to environmental effects. In contrast, the analysis of behavior gives a central role to the environment, and therefore employs concepts such as reinforcement schedules and stimuli control. In this document presents the cognitive-behavioral discussion about choice behavior. In addition, we compare their methods through two experiments dealing with the base-rate fallacy. In the experiments, the characteristics of the stimuli (verbal and non-verbal) are varied and contrasted. The paper concludes that this fallacy occurs on a smaller scale when there are less irrelevant stimuli.
