Out of Mind: Varieties of Unconscious Processes
Edited by Beatrice de Gelder, Edward de Haan, and Charles Heywood. New York: Oxford University Press, 2001. 301 pp. Cloth, $85.

This edited volume is something of a Festschrift to Oxford neuropsychologist Lawrence Weiskrantz, whose introduction of blindsight nearly 30 years ago nurtured the study of implicit perception. Each of the 15 chapters refers to and acknowledges his inquiry into residual vision following striate damage. Weiskrantz himself provides a charming afterword to this multiauthor collection. In fact, this volume is the fleshed-out proceedings of the "Varieties of Nonconscious Processes" symposium that took place in November 1998 at Tilburg University, at which Weiskrantz was awarded an honorary doctorate. Additional authors were subsequently invited to expand this book about unconscious cognition.
