Behaviorism is a learning theory that views learning as a process of response to stimuli and reinforcement. It believes that rewarding desirable behaviors will strengthen those responses and lead to changes in behavior. According to behaviorism, learning is observable through changes in behavior or performance in response to environmental stimuli. The environment is seen as the most significant factor influencing learning. Memory does not play a prominent role, and forgetting is viewed as the lack of reinforcement of a behavior. Transfer occurs through generalization to similar situations. Behaviorism best explains learning involving discriminations, generalizations, associations, and chaining of behaviors.
