ABSTRACT
Activity theory is a theoretical framework for studying different forms of human activity. The study of personality and individual differences is a critically important area of activity theory. From the activity theory perspective, people are developed
through their activity. In activity theory, special attention is given to the interrelationship of personality and activity. In activity, the subject not only changes a situation or object but also develops his or her own personality features, which are formed through activity and social interaction. Activity acts as a mediator connecting personality with the social world. That is, the psychological characteristics of the individual are not completely derived from the social environment.
