This manual describes a scoring system for TAT stories and other verbal fantasy material to assess the Psychosocial Development of any individual. There are four stages of development parallel to those outlined by Freud and Erickson. Practice stories accompanying this manual are available separately. Only trained psychologists familiar with TAT scoring systems can use the system described here after achieving the recommended level of reliability on practice stories. This system is useful to locate the maturity level (psychosocial, emotional etc) of any individual. Research results are available on youth and adult groups.
