A Study of the Intellectual Ability of the Aged - The Relationship between the Degree of Difficulty and Performance -

Abstract

In this study, the intellectual ability of the aged was measured and the relationship between the degree of difficulty and performance of tasks comparatively assessed with the results for younger people. The aged group showed lower performance in both the “rate of achievement” and the “rate of correct answers” given. However, the “rate of correct answers” with the “verbal language comprehension” test in the aged dropped significantly less as the degree of difficulty increased than with the younger group.
