| Abstract: | The aim of this study was to test the psychoanalytic notion that there is a gradual progression with age from primary to secondary process thinking. Three cohorts of children, age 6, 9, and 12, were administered the Rorschach procedure at yearly intervals—twice for the oldest cohort and three times for the two younger ones. No support was found for the developmental hypothesis in terms of aggressive content of the responses and the related defenses. The expectation of more aggressive content at earlier ages, as a reflection of more primitive aggressive drives, was not confirmed. |
