but he also read the draft of every chapter and offered many
valuable, specific comments and suggestions. Second, we
are grateful to our colleagues and collaborators, most no-
tably Lyle Bourne and John Capaldi, for their helpful advice
at many stages of this project. Third, preparation of the book
and Chapter 11 benefited from the appointment of the sec-
ond edition as a fellow of the Center for Behaviorial and
Social Sciences, School of Liberal Arts, Purdue University
during fall, 2000. The book preparation also benefited from
Army Research Institute Contract DASW01-99-K-0002 to

the University of Colorado, which supported the first editor

during summer, 1999, 2000, and 2001. Finally but by no

means least, we wish to thank our spouses, Bruce Healy and

Janet Proctor, who have provided unfailing support, under-

standing, and encouragement as we required extra time to

devote to this project on top of our normal teaching, re-

search, and writing schedule.
