This document is an English-language abstract (approximately 1,500 words) of a three-part volume on the psychology of child personality development. In part one, the author shows that psychology is one of the most important scientific disciplines on which education is based, particularly because of its contribution to the scientific planning of curricula. The author's attitude to the different psychological schools that have attempted to solve the problem of personality from Wundt to Sparanger and Stern is briefly noted and Freud's treatment of the psychology of personality is discussed in more detail. The second part of the book discusses the general conceptions of personality and its shaping in childhood, based on the classification and summarization of a large number of experimental facts and partial patterns assembled by the author over the course of many years. The last part talks about the formation and shaping of the personality at each stage of growth in some detail. The general trends of personality development at different ages discovered by Bozovic have made it possible to formulate some ideas about the drive behind such development. He concludes that the greatest drive is the need for new sensory impressions. (Author/GDB)
