Decision theory is a uniquely interdisciplinary field of study with contributions from economics, statistics, mathematics, philosophy, operations research, and psychology. The 1970s had seen important changes in research on behavioral decision theory in terms of a shift from a reliance on economic and statistical models to an emphasis on concepts drawn from cognitive psychology. Originally published in 1980, Cognitive Processes in Choice and Decision Behavior contains papers that explore the reasons why these changes had come about and discuss the future directions to which they pointed. It was clear at the time that research in behavioral decision theory was changing dramatically. The chapters in this book represent a good assessment of the reasons the changes were coming about and some of the merits and problems of the directions in which it was moving. Today it can be read in its historical context.
