This book is designed to help parents and professionals respond to the behavioral potential of children and adults diagnosed with autistic spectrum disorder (ASD) through the application of the Feuerstein method, an approach that brings an alternative and innovative treatment modality that uncovers and enhances the learning potential that traditional diagnoses and treatment methods often overlook or discourage. The method is based on Reuven Feuerstein’s formulations of cognitive modifiability and has been implemented successfully and confirmed by both research results and the experiences of teachers and parents. This book is a valued resource for treatment, including descriptions of the basic concepts of the method and their application to the assessment and treatment of those functioning within the spectrum. Each chapter is specifically written by members of the Feuerstein Institute clinical and research team. The chapters are interspersed with case studies that illustrate the principles and practices described therein and is written in an accessible and clear language for practitioners and parents. Presenting a new and optimistic paradigm in defining and responding to ASD, this is an invaluable resource for parents and practitioners concerned about meeting the needs of the ASD individual and acquiring insights and techniques for seeking or implementing treatment.
