Effect of Positive and Negative Instances on Rule Discovery: Investigation Using Eye Tracking

Abstract

This study investigates how participants reject an initial rule when they face positive and negative instances of an initial rule. Using eye movement data, we analyzed a perspective that indicated the type of rules that participants consider. The results show that, only in negative instances, participants considered rules from the perspective that they used for finding and confirming the initial rule. We concluded that, when participants face negative instances, they tried to change the initial rule peripherally to explain them. This appeared in the form of a longer consideration from an initial perspective in negative instances.
