Which two psychological models are foundational to the understanding of abnormal behavior?

The choice of psychoanalytic theory and behaviorism as foundational psychological models for understanding abnormal behavior is well-founded due to their significant historical and theoretical contributions to the field of psychology. Psychoanalytic theory, developed by Sigmund Freud, emphasizes the role of unconscious processes and early life experiences in shaping behavior. It provides a framework for understanding how unresolved conflicts, particularly those rooted in childhood, can lead to psychological distress and abnormal behavior.

On the other hand, behaviorism focuses on observable behaviors and the learning processes that influence them, emphasizing the impact of the environment on individual behavior. This model highlights how maladaptive behaviors can be learned and reinforced, providing a basis for understanding and treating various psychological disorders through behavior modification techniques.

Together, these two models offer a comprehensive perspective on abnormal behavior by addressing both the internal, unconscious influences and the external, observable behaviors. This combination has paved the way for various therapeutic approaches and interventions in clinical psychology, making psychoanalytic theory and behaviorism foundational to the study and treatment of psychopathology.
