Abstract
The purpose of this study was to investigate the relationships between salient dimensions employed in interpersonal perception by individual perceivers and some personality variables (self concept and needs). 299 undergraduates were asked to rate 8 role persons on 20 bipolar scales of personality traits. Perceptual dimensions were obtained by the analysis after Carroll & Chang's (1970) INDSCAL model. About a month later, Self-Differential Scale (Nagashima et al., 1966) and KG-SIV (Gordon & Kikuchi, 1975) were administered to the subjects. The former has been used to assess one's self concept, and the latter to examine personal values and needs.
The major findings were as follows:
1. The dimensions extracted from INDSCAL solution of personality rating data were highly similar to those of the previous study (Hayashi, 1979). These dimensions were interpreted as (1) dynamism and general evaluative bias, (2) social desirability, and (3) intimacy.
2. There are some individual differences. Subject's interpersonal cognitive structure, measured by differential weights he or she gave to the dimensions, was stable over 7 weeks.
3. Each individual's salient dimensions were related to his or her self concept in a curvilinear manner. In addition, these dimensions were closely related to perceivers' personal values and needs.
4. Significant sex differences were found in the relationships mentioned above.
