Understanding the conditions under which variability in performance may arise, and the processes related to its emergence, gives us insight into the development of techniques for improving the quality of performance. Variability in Human Performance details the scientific and the practical implications of human performance variability by providing a broad perspective on how and why such variability occurs across a number of disciplinary domains. The text takes an approach that rests upon the idea of context, or design, specificity in performance, namely that variability in performance is closely referenced to design factors in the environment in which performance is occurring.
An exploration of the link between variability and related processes, the book introduces a comprehensive framework for understanding human performance variability, presented in terms of how human control of behavior is closely tied to design factors in the performance environment. The authors introduce empirical evidence, as well as practical examples and application areas, in support of this framework. The book begins with coverage of neurobiological and biomechanical basis of movement variability, then examines rich and extensive empirical evidence available for context specificity in cognitive performance and learning, as a basis for cognitive performance variability. The book then reviews the evidence for context specificity in:
Student learningDisplaced feedback conditionsHuman error behaviorAffective performanceSocial and team performance
The authors also explore work performance as influenced by complex sociotechnical systems and as a basis for performance variability, applying control systems concepts to an interpretation of the nature and basis of performance variability in all of these domains. They conclude by taking an evolutionary perspective on the origins and behavioral significance of human performance variability. The book then provides strategies on how individuals, groups, and organizations can significantly reduce variability in human performance that often leads to systems failures.

"Throughout, the book focuses on the sources of variability in human performance, including the design of work systems. The book will therefore be of interest to a wide range of HFE specialists."
-RS Bridger, Institute of Naval Medicine
"This is a truly excellent book that increases awareness of the study of variability in movement performance. ... Importantly, this book provides exciting discussions on theoretical problems on movement variability such as what are the sources of this variability."
-DR. Nick Stergiou, University of Nebraska Omaha and University of Nebraska Medical Center
