Progress in Behavior Modification, Volume 3, is a multidisciplinary serial publication that encompasses the contributions of psychology, psychiatry, social work, speech therapy, education, and rehabilitation. This serial aims to meet the need for a review publication that undertakes to present yearly in-depth evaluations that include a scholarly examination of theoretical underpinnings, a careful survey of research findings, and a comparative analysis of existing techniques and methodologies. The discussions center on a wide spectrum of child and adult disorders. The present volume opens with a chapter on behavior modification and hypnosis. This is followed by separate chapters on applications of behavior modification procedures in classroom settings; smoking behavior modification; and psychotherapy outcome research. Subsequent chapters deal with the behavioral approach to teaching learning disabled children; evaluation of animal analogues of behavioral treatment; therapy for sexual dysfunction; and research in the area of transfer of training of operant treatment effects with children.
