`A useful book for the specialist engaged in assessment and research'. - Journal of Analytical Psychology `This book is a must-have for the bookshelf if you are a student or practitioner in the fields of psychology or even sociology. It will be of equal value to anyone working in the fields of brain injury, mental health or related fields. It is a handbook of references, terms and abbreviations related to neuroanatomy, psychology, medicine and their experiments and therapies, as well as dipping in and out of statistical processes and their meanings. The book will have broad appeal from student to practitioner to doctor. This book is a new and improved second edition.
