Abstract
Kudo, Y. (2003) considered a new way of explaining “example effects”, that is, the effect in which example used when teaching rules influence post-test scores, and showed that “example effects” can be explained by example-based induction. The purpose of this study is to investigate the remaining problems in Kudo’s study. Subjects were explicitly taught a rule of hay fever, using the example of cherry or Japanese cedar. The main results were as follows: Whether subjects could extract the rule or not, “example effects” occurred in post-test. Not all “example effects” could be explained by example-based induction.
