The study of psychology has been crucial to understanding human behavior and the human mind as early as 1000 BC (Rescorla). Through its wealth of research and study, psychology has provided valuable insights into the human mind and how it works. This knowledge, however, draws on many models of psychology and requires a complete understanding of all psychological models to be successfully applied to understanding human behavior. The four main models of psychology are the biological model, the psychodynamic model, the cognitive model, and the behavioral model. Each model brings its own take on psychology concepts, but more often than not, each model attempts to distance itself from the other models by attempting to present itself as the superior model. The biological model appears to be the main culprit for such a separation, as it relies far too heavily on prescription drugs and medical interventions and ignores other treatment methods that could be far more effective. The separate evolution of these models appears to significantly limit the value of psychological research, as an integration of all models could reveal valuable insights for the psychological community. Each model has diverged and converged toward its own theories and practices, but it has done so separately and in isolation from each other. This separation of psychological models is clearly demonstrated by the biological model, which relies heavily on biological methods and ignores other valuable approaches to research. mental disorders. The branch of biological psychology seems to evolve most separately from other models, because it rarely consults other models for ideas that biology cannot explain.
