State and Trait

This third volume of Handbook of Human Performance addresses individual differences in human performance. The book considers both effects related to stable characteristics and those which are a product of either endogenous changes in state, or induced by task performance itself. It includes chapters on intelligence, demographic factors, extra version, and fatigue. Although a wide range of topics is covered, all contributions are linked in a consistent manner to human performance.
