Goetzinger (1968)

Charles Goetzinger conducted an experiment using the mere-exposure effect on his class at Oregon State University. Goetzinger had a student come to class in a large black bag with only his feet visible. The black bag sat on a table in the back of the classroom. Goetzinger's experiment was to observe if the students would treat the black bag in accordance to Zajonc's mere-exposure effect. His hypothesis was confirmed. The students in the class first treated the black bag with hostility, which over time turned into curiosity, and eventually friendship. This experiment confirms Zajonc's mere-exposure effect, by simply presenting the black bag over and over again to the students their attitudes were changed, or as Zajonc states "mere repeated exposure of the individual to a stimulus is a sufficient condition for the enhancement of his attitude toward it".
