Abstract
Several evidences revealed that visuo-spatial working memory related to some cognitive performance. In this study, we examined effect of display size on performance of visuo-spatial working memory task for young and older participants.
In Experiment 1, we examine the age difference of the effects of stimuli size on the same normal size monitor for spatial working memory. In Experiment 2, we examine the age differences of the effects of display size using the large and the small monitor for spatial working memory.
Experiment 1 suggested that the recall performance of the small stimuli condition was higher than the large stimuli condition among young participants. In older participants, there were no effects of stimuli size. In Experiment 2, there were main effects of age (Young > Older) and monitor size (Large monitor > Small monitor), but no main effect of retention time.
The small size stimuli enhanced spatial memory performance. But, the effects of small stimuli for spatial working memory were not observed among older adults. The large monitor can improve spatial memory performance and visuo-spatial cognitive processing in both age groups. This result is discussed in terms of the distinctiveness on the large display.
