The problem of child autism in modern society is becoming more and more urgent. Children with autism need psychological and pedagogical support and special assistance in the process of socialization. This book presents the results of a longitudinal study on the emotional and personal development of children with autism in early childhood. The specificity of this process is analyzed in terms of intra-personal changes, namely, the dynamics of the relationship between "True" and "Fake Self". Based on the research results, a classification of autistic disorders was developed depending on the level of emotional and personal development of children. For each of the groups, the mechanisms of occurrence of disorders were identified, and compensation methods and dynamics were described. The significance of symbolism for assessing well-being in personal development and adaptation to the environment was shown. The resulting classification can be used in diagnostics, in forecasting development and socialization, and in planning therapy strategies. The presentation of the study results is supplemented by case studies and case analysis materials. The book is addressed to specialists - psychologists and teachers.
