    Behaviorism is a psychological theory that emphasizes observable behaviors, conditioning, and environmental influences on learning and behavior.

    Central to behaviorist principles is the concept of classical conditioning pioneered by Ivan Pavlov, where a neutral stimulus becomes associated with a meaningful one to elicit a response. On the other hand, operant conditioning, introduced by B.F. Skinner, explores how consequences of behavior, like reinforcement or punishment, shape future actions. Reinforcement, both positive and negative, plays a crucial role in this process, with rewards increasing the likelihood of a behavior recurring. Behavior modification techniques, such as shaping and chaining, are also employed to establish desired behaviors through a series of manageable steps.

    Psychoanalytic Theory

    Psychoanalytic theory, developed by Sigmund Freud, delves into the unconscious mind, early childhood experiences, defense mechanisms, and psychological disorders as outlined in the DSM-5.

    Freud’s groundbreaking theory distinguishes three distinctive components of the human psyche: the id, ego, and superego. The id, driven by primal instincts and desires, operates on the pleasure principle. In contrast, the ego serves as the rational mediator, navigating between the id’s impulses and the superego’s moral dictates. The superego, representing societal norms and values, instills guilt and moral standards. Freud proposed a range of defense mechanisms such as repression, projection, and sublimation to protect the psyche from internal conflicts and anxiety.

    Humanistic Psychology

    Humanistic psychology focuses on individual potential, self-actualization, personal growth, and subjective experiences, emphasizing the importance of human agency and positive psychology.

    Central to humanistic psychology is the belief that individuals innately strive to reach their full potential, focusing on the unique qualities and strengths that make each person distinct. This perspective rejects the deterministic views of behaviorism and the clinical focus of psychoanalysis, instead, placing a profound emphasis on the autonomy and creativity of each individual.

    Self-fulfillment is a fundamental concept in humanistic psychology, highlighting the idea that individuals have the capacity to fulfill their inner potential and lead meaningful lives. This approach values the exploration of one’s feelings, beliefs, and aspirations, encouraging individuals to seek authenticity and personal growth.
