The relationship between representation of a person and evaluative impression of that person was investigated by presenting two stimulus persons, each by six trait adjectives, to subjects of the impression group, memory group, and category group. The representation was measured by two kinds of RTs and the amount of recall, and the evaluative impression by ratings on S-D items. When subjects' representation of a stimulus person contained less information for impression ratings, the resulting impression was stable and consistent with the implicit personality theory. As the amount of the information increased in the order of the impression, category, and memory groups, however, the stability of the impression ratings declined even for the same stimulus person.
