also to Shirley Jackson and Ramsay Selden for keeping the project on track
when it was in danger of falling off. More recently, support for completing
this volume has come from Vernetta Stevenson and Jeff Schiller, of NIE, and
from Diane Vines and her staff in the Education Department. Special thanks
go to Marilyn Binkley for her help in editing and completing the references
and index.

E. H. White and Company, under contract with NIE, provided support
for the synthesis project. They managed the 1982 workshop and assisted in
preparing the final manuscript. Staff who deserve special thanks include Ted
Allen, Barbara Dutchak, Regina Kyle, Margaret Charles, who typed and re-
typed chapters, and Eileen Vedral.

Editorial work on this book began while I was on the staff of NIE; it was
completed after I moved to the Army Research Institute (ARI). Special ap-
preciation goes to Robert M. Sasmor, Director of Basic Research at ARI, for
his support during the final stages. Finally, I want to thank my husband, Er-
nest, for his patience, encouragement and ever present good humor.
