Abstract
Human Change Processes (Mahoney, 1991) is an attempt to set experiential psychotherapy on a scientific basis. The first tow-thirds of the book, based on an extensive survey of diverse scientific and scholarly literatures, argues fairly convincingly for a conception of human beings in which attachment, subjectivity, emergent and unconscious mental processes-especially regarding the self-and emotionality are central to human development and psychotherapeutic change. The book's last part, a discussion of experiential psychotherapy, based largely on clinical experience and intuition, is vague on important points of psychotherapeutic procedure ad process and is less convincing. The disjunction between the scientific discussion of psychology and the non-scientific discussion of psychotherapy is the book's major flaw. Nevertheless, the book is important as an attempt to synthesize a psychotherapy that is at once humanistic and scientifically informed.
