# Psychology

Psychology is the study of mental functions and behaviors. Psychology seeks to understand individuals and groups by establishing general principles and researching specific cases.

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 biological processes that underlie cognitive functions and behaviors.
