The Twenty Statement Test (TST) was administered to four groups of subjects consisting of fifth graders in an elementary school, second graders in a junior high school, senior high school and university. In addition to the traditional analysis of TST in which the major emphasis is on content aspects of mode of self with respect to elementary contents of self-descriptions, further analysis was undertaken in terms of structural aspects of mode of self by focusing on the relation of the self with the elementary contents of self-descriptions. The results of the content-oriented analysis conformed in general to those reported by other investigators in the past. The structurally-oriented analysis indicated a decrease in descriptions of the relationship of the self to things, events and persons in one's environment and an increase in these aspects with respect to one's own traits. It was suggested that by employing both these analytic procedures, an enhanced understanding of self-concept might be facilitated.
