Psychology is the science of behavior and mind, including conscious and unconscious phenomena, as well as thought.
In addition to employing empirical and deductive methods, some clinical and counseling psychologists rely upon symbolic interpretation and other inductive techniques.
Psychology has been described as a “hub science”, with psychological findings linking research and perspectives from the social sciences, natural sciences, medicine, humanities, and philosophy.
It is not new.
As early as 400-300BCE a text known as The Yellow Emperor’s Classic of Internal Medicine identified the brain as the nexus of wisdom and sensation, included theories of personality based on yin–yang balance, and analyzed mental disorder in terms of physiological and social disequilibrium.
