This book presents new theory and empirical studies on the roles of
cognitive workload and fatigue on repeated financial decisions. The
mathematical models that are developed here utilize two cusp catastrophe
functions for discontinuous changes in performance and integrate
objective measures of workload, subjective experiences, and individual
differences among the decision makers. Additional nonlinear dynamical
processes are examined with regard to persistence and antipersistence in
decisions, entropy, further explanations of overall performance, and the
identification of risk-optimization profiles for long sequences of
decisions.
