Psychology is the
study of behavior and mind, embracing all aspects of conscious and
unconscious experience as well as thought. It is an academic
discipline of immense scope and diverse interests that, when taken
together, results in understanding of the emergent properties of brains, and all the variety of epiphenomena they manifest. A
professional who studies this mental behaviour is called Psychologist. He also explores the physiological and biological processes that
underlie cognitive functions and behaviors. They study the
relations between brain function and behaviour and environment and behaviour.
