Age-related differences in spatial ability have been suggested as a mediator of age-related differences in computer-based task performance. However, the vast majority of tasks studied have primarily used a visual display (e.g., graphical user interfaces). In the current study, the relationship between spatial ability and performance in a non-visual computer-based navigation task was examined in a sample of 196 participants ranging in age from 18 to 91. Participants called into a simulated interactive voice response system and carried out a variety of transactions. They also completed measures of attention, working memory, and spatial abilities. The results showed that age-related differences in spatial ability predicted a significant amount of variance in performance in the non-visual computer task, even after controlling for other abilities. Understanding the abilities that influence performance with technology may provide insight into the source of age-related performance differences in the successful use of technology.
Keywordsinteractive voice response systems; aging; cognitive abilities; interface In light of evidence that cognitive abilities play an important role in the performance of everyday activities (e.g., Diehl, Willis, & Schaie, 1995), researchers have attempted to identify and measure the influence of cognitive abilities on a wide variety of activities (e.g., Czaja et al., 2006;Kelley & Charness, 1995;Sharit, Czaja, Nair, & Lee, 2003). One such ability, spatial ability, has been shown to be predictive of performance on a wide variety of everyday tasks such as way finding, map reading and computer tasks such as text-editing, spreadsheet usage, map-and computer-based information search tasks, even when other more general ability factors are controlled (for a review, see Pak, Rogers, & Fisk, 2006). Spatial ability is generally defined as the ability to perceive and transform visual patterns (Ekstrom, French, Harman, & Dermen, 1976). In studies examining spatial ability and computer-based information search, measures of spatial ability (e.g., paper folding, cube comparison) show significant relationships © 2008 Elsevier Ltd.
