Synopsis The fourth psychosocial crisis is handled, for better or worse, during what he calls the “school age”, presumably up to and possibly including some of junior high school. Here the child learns to master the more formal skills of life: (1) relating with peers according to rules, (2) progressing from free play to play that may be elaborately structured by rules and may demand formal teamwork, such as baseball and (3) mastering social studies, reading, arithmetic. Homework is a necessity, and the need for self-discipline increases yearly. The child who, because of his successive and successful resolutions of earlier psychosocial crisis, is trusting, autonomous, and full of initiative will learn easily enough to be industrious. However, the mistrusting child will doubt the future. The shame- and guitfilled child will experience defeat and inferiority.
