Behavioral theory is a psychological perspective that focuses on how behavior is learned and shaped through interactions with the environment. It suggests that behavior is a result of conditioning and reinforcement, with individuals repeating behaviors that are rewarded and avoiding those that are punished. This theory emphasizes the importance of observable behaviors and the influence of external factors on behavior. It also highlights the role of learning, experience, and socialization in shaping an individual's actions and reactions. Overall, behavioral theory provides insights into how behavior is influenced by external stimuli and the consequences of actions.
