This volume, like the other eight in the Current Issues in Autism series, grew from our annual TEACCH conference. The book is not, however, simply a compilation of conference proceedings. Instead, selected con­ ference participants whose work has already achieved national and inter­ national recognition were asked to develop chapters around their pre­ sentations. Other recognized experts in areas relevant to the conference theme were also asked to contribute chapters. Although we were not able to include all of the workers who have contributed to the theme, this volume represents our best effort to pull together for our readers the most current knowledge and state of the art practices. Although aspects of cognition, learning, and behavioral motivation have been touched on for relevance to autism in other books in this series, the growing integration of behavioral and cognitive theories has greatly enriched our educational interventions on behalf of autism. While this volume does not include all the fascinating facets of this recent integration, we believe that it offers useful information to teachers, parents, and re­ searchers on some of the progress produced by their interaction.
