血液型ステレオタイプ形成におけるプロトタイプとイグゼンプラの役割 The roles of prototype and exemplar in the formation of the "blood type stereotype"
This study investigates the roles that two types of information-prototype and exemplar-play in the formation of "blood type stereotypes." The result of a questionnaire study (with 112 college students) confirmed hypotheses concerning the role played by these two types of information. A substantial discrepancy was found between the subjects' beliefs about the blood type-relevant personality traits and the commonly and publicly assumed blood type traits. There also found a substantial variation in subjects' beliefs in this respect. It was found that the exemplar information played an important role, at least among some respondents, in the formation of the "blood type stereotype," such that subjects generalized their personality traits as the traits typical to people with the blood type of their own. The other respondents, on the other hand, seemed to have formed the "blood type stereotype" by adopting the prototypical personality traits commonly believed to characterize people of their blood type.
