Acknowledgments

I received a great deal of help with writing and publishing this book. It would have been impossible without the support of my family, East Apthorp and Anders Apthorp Lucius Malmberg. Readers of earlier versions of the manuscript, who provided valuable comments and advice, waded through rough ideas, numerous typos, and grammatical errors. (Those that remain are my fault.) So thank you, Nelson Cowan, Chad Dubè, James Juola, Jeroen Raiijmakers, Larry Squire, and John Wixted. I also thank Denis Cousineau, David Huber, and Saul Sternberg for their discussions, David Drucker and Erin Hunter for their assistance, and Judy Kroll for her graduate seminar on cognitive science. Thank you to Stephen Accera and Sally Evans-Darby at Cambridge University Press for all the hard work in getting the book off the ground and completed. Finally, I thank Richard Atkinson for his advice and enthusiastic encouragement, and Richard Shiffrin for years of productive, entertaining, and intellectually adventurous friendship.
