Abstract

In an aged society, easy-to-use information devices are necessary. In order to develop information devices which elderly adults can use easily, it is important to bring out characteristics of elderly adults in using information devices based on their cognitive functions. In this study, the authors focus on a relation between memory function and exploration behavior in a hierarchical menu while learning process. An experiment is conducted with eight elderly adults and eight young adults. In this experiment, a hierarchical menu composed based on the library classification, not actual hierarchical menus, is used in order to eliminate differences of knowledge about information devices between elderly and young adults. As a result, it seems that decrease of episodic memory increases a possibility of improper selections in the hierarchical menu when doing the same operations as previous operations.
