| Outline of Final Research Achievements |
In this study, we focused on effects of abstraction of instance space in rule discovery. We revealed that (1) abstraction of each instance contributes to find a rule underlying a huge instance space. In particular, (2) focusing on superficial features of each instance was dominant in the early phase of problem solving and decreased toward the middle phase, while focusing on structural features tended to increase from the middle phase to the late phase. Moreover, self-reflection reflecting on their own actions increased at the last phase of problem solving. This implies that self-reflection becomes possible after the abstract understanding of each instance has progressed. Finally, (3) we verified that the abstraction of each instance facilitates searching for the instance space by constructing and simulating a cognitive model for searching for a large amount of an instance space.
