'Rosen provides an intelligent, contemporary and engaging account of the formative periods and domains of individual and social development, vital to an understanding of what it means to be human.' - Professor Howard Steele, The New School, USA 'This is the definitive textbook on attachment and the development of the self - a key topic for students of development as well as clinicians of all orientations. It is a comprehensive and well-organized presentation of a complex and often difficult-to-access area, written in a crystal clear and engaging style.' - Professor Peter Fonagy, University College London 'This is not a superficial treatment of the topic, but Rosen succeeds in making the content readily available to students and very engaging. She takes a questioning approach to the research which ignites the readers' concern and interest. The book is rich in detail, scholarly and up to date, providing an in-depth introduction to material central to the study of social and emotional development in infancy through to adolescence.' - Dr. Brenda Todd, City University London 'An engaging text that integrates cutting edge research from a range of aligned disciplines to explore the importance of the social relationships that we form during childhood and adolescence.' - Dr. Lucy Betts, Nottingham Trent University
