Psychological Development in the Elementary Years is the second in a series of reviews relating current theory and research on psychological development to educational practice. The book discusses the significance and change in psychological sex roles; peer relations; and the development and regulation of aggression in young children. The text also describes the acquisition of self-control; the developmental trends in the learning processes; and the foundations and direction of cognitive development. The theory and research on children's achievement; the family influences on language and cognitive development and the personal and social causation in the school context are also considered. The book further tackles the behavioral perspective of children with learning and behavior problems. Psychologists, psychiatrists, behavioral psychologists, and students taking related courses will find the book invaluable.
