Psychology is the science of mind and behavior. Psychologists attempt to understand the role of mental functions in individual and social behavior, while also exploring the physiological and neurobiological processes that underlie certain functions and behaviors. Psychology incorporates research from the social sciences, natural sciences, and humanities such as philosophy.
Most psychology departments usually split psychology into two broad categories: experimental (or research) psychology and clinical (or applied) psychology.
Psychology is a social science but is related to natural sciences such as biology and chemistry. It is also related to medical sciences such as neuroscience and psychiatry.
