How and why does restorative practice (RP) work? This book presents the biological theory, affect script psychology (ASP), behind RP, and shows how it works in practice in different settings. ASP explains how the central nervous system triggers 'affects' which are the basis of all human motivation and emotion. The book presents a clear explanation of what ASP is, how it relates to RP, and how ASP helps practitioners to understand relationships, emotions and dynamics in their work. The chapters are based around case studies which demonstrate RP in criminal justice, organizational and education settings. They show how theory links to practice, and how having a deep understanding of the theory has helped practitioners to be successful in their work.Providing an accessible explanation of how RP works, this book will be invaluable to all RP practitioners in any setting, as well as RP students and academics.
