The research objective is in analysing the main psychological approaches in development of the requirement theory for detection of distinctions in psychological and philosophical approaches in understanding the requirement. If for modern philosophy the requirement is the main determinant of activity, in psychology the requirement is considered as a part of behavior motivation. Psychologists focus their attention to motivation, and in social philosophy requirement consideration is as an objective-necessary determinant of human activity.
