This book is for psychologists, educators, child development professionals, and general readers. It contains an up-to-date understanding of childhood, trauma, and resilience. It addresses the impact of interferences on development, mental health and personality, based on the dynamic theory of child development that allows us to explain early experiences and their relationship with adult psychopathology. With the support of their extensive research experience, the authors present a psychological intervention strategy for psycho-affective recovery in boys and girls through playful-educational techniques.
