Abstract
An important finding in the field human-computer interaction and psychology is that differences in spatial ability may be responsible for individual differences in performance on computer-based tasks. However, methodological issues plague many studies examining spatial abilities and computer-based task performance. This presentation reports two studies that are being conducted. The first study was designed to resolve two main issues important for understanding spatial abilities and computer-based task performance. In this study, spatial ability and spatial demand of the task are manipulated. The study was designed to examine the relationship between spatial ability and computer-based task performance in older adults. The second study explicitly examines older adults' performance in a computer task and how it is related to spatial ability.
