The idea for this volume took root during a recent annual convention of the American Psychological Association. The contributors share a common vision of research in their particular area and have had an opportunity to debate and clarify their ideas. Taken as a whole, the fifteen chapters provide an exciting perspective of the field and form a basic set of readings for courses on individual and group decision making in a variety of disciplines. The coverage from basic laboratory research to complex applied group decision processes should challenge researchers and students to pursue the field of decision making as enthusiastic scientists and practitioners.
