    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, construction industry, aviation, and human-computer interaction.


    • Presents new SSAT data

    • Offers, for the first time, comparative analysis of studying efficiency and productivity from the perspective of ergonomics, psychology, and economics

    • Includes examples of evaluation of economic efficiency of ergonomic innovations

    • Provides advanced self-regulative models of activity and of all cognitive processes that describe strategies of task performance

    • Introduces a new efficient method of morphological and analytical quantitative analysis

    • Discusses new methods of evaluation of complexity and reliability of highly variable computerized and computer-based tasks

    Work Activity Studies Within the Framework of Ergonomics, Psychology, and Economics presents a comprehensive unified psychological theory that can be utilized as a general approach to the study of human activity not only for ergonomists and psychologists, but also for economists that study the efficiency of human performance.


    Dr. Gregory Bedny has taught psychology at Essex County College and now he is a Research Associate at Evolute, Inc. Dr. Bedny earned PhD in Industrial Organizational and a Post-Doctorate Degree (ScD) in Experimental Psychology. He is also a board-certified ergonomist. He has authored and co-authored 6 original scholarly books in English published between 1997 and 2015 by Lawrence Erlbaum Associates, Inc., Taylor and Francis Group and CRC Press. Dr. Bedny has developed Systemic-Structural Activity which is the high-level generality theory that offers unified and standardize methods of the study of human work. He applied his theoretical studies in the field of human-computer interaction, manufacturing, merchant marines, aviation and transportation, robotic systems, work motivation, training, reducing fatigue.

    Dr. I. S. Bedny is a computer professional with Ph.D. in Experimental Psychology. She is doing research applying SSAT to Human Computer interaction. She is the author or co-author a number of scientific publications in the field of HCI. In 2015, she has co-authored the book Applying Systemic-Structural Activity Theory to Design of Human-Computer Interaction Systems published by CRC Press. She also has experience teaching math and physics at a high school level and training computer professionals. Dr. I. Bedny is also a Research Associate at Evolute, Inc.
