"Ecobehavioral analysis," the merging of social ecological studies and J.R. Kantor's theory of interbehavioral psychology, was termed just over a decade ago. Since then, innovative trends emerging in the field of developmental disabilities warrant a comprehensive update. Ecobehavioral Analysis and Developmental Disabilities The Twenty-First Century offers such an update of current research, as Dr. Stephen Schroeder compiles the work of twenty-one noted authorities in this volume. Each contributor discusses his/her research on a personal level, providing fresh insights into various aspects of the field. Experiential research ranging from the naturalistic observations of behavior-environment interactions in the classroom to ecobehavioral studies in pharmacotherapy is also presented.
