I bought this book because my old copy literally fell to pieces from so much use.
Psychological development "milestones". Combines studies by Freud, Erikson, and Piaget
Outlines how personality may be expected to develop during Erik H. Erikson's (1902-1994) 8 Stages of development. At each stage he asks "What relationship, what issue, concerns us most"? Describes satisfactory and the unsatisfactory responses to each crisis. Also considers regression to earlier stages, and how they are used in media advertising.
For some reason his actual age ranges for development stages differ from Erikson's. I guess we should not take them too literally - people are so variable.
