Description

Inhibition of return (IOR) is a cognitive mechanism to bias attention from returning to previously engaged items. While aging models have proposed deficits within select inhibitory domains, older adults have demonstrated preserved IOR functioning in previous studies. The purpose of the present study was to determine whether IOR associated with objects showed the same age patterns as IOR associated with locations. Both young and older adults produced significant location-based IOR in static and dynamic paradigms. In contrast, young adults produced object-based IOR in a dynamic paradigm, whereas older adults failed to produce significant object-based effects. The findings provide partial support for unique age-related inhibitory patterns associated with anterior and posterior attention systems.
