Abstract: | Conceptual system as a cognitive-developmental variable in personality has been assumed to relate to different cognitions of self and others and of interpersonal relations at each developmental stage. The assumed relationship between conceptual system and some personality variables was studied in a group of students (N = 85). The “This-I-Believe” test (TIB) [Harvey, O. J. System structure, adaptability and creativity. In O. J. Harvey (Ed.), Experience, structure, and adaptability. New York: Springer, 1966.] for assessing the developmental stage of the conceptual system was administered together with personality scales for traits assumed important in socialization. A modified TIB scoring procedure was used. Highly significant differences in personality were obtained by a MANOVA, using conceptual system for classification. One dimension accounted for discrimination. Measures assumed to relate to sensitivity for and conformity to a social environment contributed most to the discrimination. |
