The precise relationship between high-functioning autism and Asperger Syndrome is still a subject of debate. This volume provides a general overview of the disorder and present diverse opinions on diagnosis and assessment, neuropsychological issues, treatment, and related conditions. A special section features personal essays by individuals diagnosed with autism or Asperger Syndrome. The result is a comprehensive and useful survey of the current state of the field that will be of great interest to clinicians, teachers, researchers, and parents.

The First International Leo Kanner Colloquium on Child Development, Devia tions, and Treatment explores relationships between experimental research, normal development, and interventions, with early infantile autism as a reference model of "relatively unambiguous abnormal development." Sponsored by the Treatment and Education of Autistic and related Com munications handicapped CHildren (TEACCH) Project at the University of North Carolina at Chapel Hill, the colloquium tackled the challenge of facilitat ing communications among scientists of different disciplines working in a spe cialized area. The meeting proved successful in generating an interplay and information exchange among scientists of diverse academic and professional orientation, who, if not completely able to agree on common factors, did nevertheless achieve awareness and clarification of their differences. The TEACCH conference and this volume have implications for all research efforts, within and outside the domain of mental health. This is particularly so at a time of limited dollar resources for research support. The present and foresee able future represent such a time-one when communication among fields, resource competition between basic and applied research, biomedical versus psychosocial research, and the question of research utilization assume a new commanding significance. Thus the question of accountability for research has come to the fore.
