Psychology is defined as the scientific study of the mind and behavior. It involves both pure psychology, which focuses on theory development, and applied psychology, which implements theories in practical settings. The major subfields of psychology include clinical, developmental, social, and cognitive psychology. Psychologists study behavior through various methods like introspection, observation, experimentation, surveys, testing, and case histories. Psychology also has important applications in healthcare by examining the biological and environmental factors that influence health.
