This book presents new data in Applied Activity Theory (AAT) and Systemic-Structural Activity Theory (SSAT), that can be used in the study of human performance. The SSAT is the high-level generality theory that offers standardized principles of the analyses of human activity. These principles can be utilized in theoretical and applied studies. This multi-contributed book offers a selection of works that will provide a holistic picture of the field. The new data can be utilized for the study of extremely complex human-machine and human-computer interaction systems, and for evaluation of...

Systemic-structural activity theory (SSAT), founded by Gregory Bedny, is a relatively new unified framework for the study of efficiency of human performance, equipment, and software design. This book presents new recently obtained data in the field of SSAT that can be used in the study of efficiency and complexity of human performance. With increased cognitive demands to task performance, psychological methods of study of human activity play an important role. New principles and revised methods for the study of human work are supplemented by practical examples in manufacturing,...
