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.
