implicit and explicit memory and thereby enable the cross-fertilization of ideas
and research.

The chapters that make up this volume were written by experts on the topic of
implicit and explicit memory. We invited them to write about their area of
research, to outline its theoretical and empirical roots, to emphasize new devel-
opments and fundamental issues, and to speculate about implications and about
promising new research directions. But unlike other collections of chapters that
report the latest findings from various research labs, the contributors to the
present volume were asked to write for a broad audience--to give a tutorial
introduction and overview--for their colleagues from allied disciplines, for new
researchers, for graduate students and for advanced undergraduate students, to
help them gain a comprehensive overview of the mushrooming research on this
topic, grasp the most fundamental empirical and theoretical issues, and focus on
new research directions.

We thank the chapter contributors for following our directions, and for reading
and reviewing each other's chapters, and we thank Lawrence Erlbaum for show-
ing patience despite several broken deadline promises. Grants from the Natural
Sciences and Engineering Research Council of Canada to both editors made this
volume possible.
