This book contains selected papers presented at the 1998 conference on Naturalistic Decision Making (NDM). The objectives of the conference were to:

*make American researchers more aware of NDM research being conducted abroad, particularly in Europe;

*connect NDM research with work in management and industry, to stretch beyond the military and paramilitary focus; and

*formulate a more explicit connection between NDM and expertise.

These objectives are reflected in the chapters of this volume.
