is an academic and applied discipline that involves the scientific study of mental functions and behaviors. Psychology has the immediate goal of understanding individuals and groups by both establishing general principles and researching specific cases and by many
accounts it ultimately aims to benefit society. In this field, a professional practitioner
or researcher is called a psychologist and can be classified as a social, behavioral,
or cognitive scientist. Psychologists attempt to understand the role of mental functions
in individual and social behavior, while also exploring the physiological and biologicalprocesses
that underlie cognitive functions and behaviors.
