About Psychological

Psychology is the scientific study of the mind and behavior. Psychology is a multifaceted discipline and includes many sub-fields of study such areas as human development, sports, health, clinical, social behavior and cognitive processes. Psychology is concerned with the experience and behaviour of the individual. Behaviour is the expression of experience, which belongs to a subject, and which is due to the interaction of subject and object. It implies the duality of subject and object. If there were no subject and object, there would be no experience.
