Abstract
Our previous four papers are based on the change in exposure frequencies by an experimental method. On the other hand, this study is concerned with a possibility of the mere exposure effect exhibited in a daily life situation. After a blue judo uniform was approved by International Judo Federation (IJF) in October, 1997, we studied whether the mere exposure effect appears in case of a blue judo uniform among judo team students in three universities who have more exposure of judo uniform. Also we studied a change in preference for the colored judo uniform among non-judo team students in a university and a college who have less exposure of judo uniform, before and after the Sydney Olympic.
Among judo team students, preference for women's blue judo uniform is increased with the passage of time, this is the mere exposure effect, while a great change in preference for a blue judo uniform was not seen among non-judo team students.
