Abstract

This study was intended to investigate the effect of social roles (senior and junior role in high school) in the perception of social events, in which senior and junior were opposed to each other. Thus, four experimental conditions was manipulated ; senior perspective contraction condition, junior perspective contraction condition, senior perspective expansion condition, junior perspective expansion condition. As a result, the perceptual dimensions to the social events were changed by the manipulations of perspective contraction or expansion. That is, in perspective contraction condition, the subjects judge events on the evaluative dimension, but, in perspective expansion condition, they judge thoes on the descriptive dimension. Thus, in the former, according to thier roles, they made a biased judgement of liklihood, causality, responsibility, impression formation of events. However, in the latter, this tendancy was reduced.
