The Quality of Test Context and Contra-evidence as a Moderating Factor in the Belief Revision Process

In this study, we describe the influences of qualitative changes to the reasoning problem on the reasoning process. The first manipulation is the quality of the test context: A rule is learned in a certain context and contradicted in another. The belief in the rule is then measured in the learning context, the contradictory context, and a new context. The second manipulation is the quality of contradiction: The contradictory rule can neutralize or inverse the learned rule. Both qualitative changes influence the belief revision process.
