ABSTRACT

General applied and systemic-structural activity theory (SSAT) can be identified under the umbrella of activity theory.

This paper is dedicated to applied and systemic-structural activity theory. These theories have been developed because application of general activity theory to work studies is not always possible. Special attention is directed toward considering activity as a hierarchically organized system. Hierarchical organization of activity includes cognitive, motor actions, and psychological operations that are the basic units of activity analysis. Activity during task performance is the main object of study in SSAT. Goal and motives are key concepts in the development of the goal directed self-regulation model of activity.

The model of self-regulation of orienting activity is presented and discussed in this work.

Examples of the application of this model are presented. Application of SSAT to job analysis, task analysis, and design of equipment, interfaces, and methods of task performance are discussed.
