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 efficiency, complexity, and reliability of such systems at the design stage.FeaturesShows examples of self-regulative models of various cognitive processesIllustrates a method of study of production process in the construction industryIncludes topics on learning, training, and managementCovers a new method of computer based automated support of decision making under risk and uncertaintyPresents a new method of evaluation of probabilistic structure of tasks, and the method of assessing reliability of human performance
