This book is intended to round out the picture of American psychology's past, adding the history of psychological practice to the story of psychological science. Written by two well-recognised authorities in the field, this book covers the profession and practice of psychology in America from the late nineteenth century to the present. From Seance to Science tells the story of psychologists who sought to apply the knowledge of their science to the practical problems of the world, whether those problems lay in businesses, schools, families, or in the thoughts, emotions, and behaviours of individuals. Engagingly written and full of interesting examples, this book includes figures and photos from the Archives of the History of American Psychology. This is the story of individuals, trained in psychology, who function as school psychologists, counselling psychologists, clinical psychologists, and industrial psychologists. These are psychology's practitioners; they take the knowledge base of psychology and use it for practical purposes outside of the classroom and outside of the laboratory.
