The role of spatial abilities and age in performance in an auditory computer navigation task

Area of Science:

• Human-Computer Interaction
• Cognitive Psychology
• Gerontology

Background:

• Age-related declines in cognitive abilities can affect computer task performance.
• Previous research focused on visual computer interfaces, overlooking non-visual interactions.
• Spatial ability is a potential mediator of age-related performance differences.

Purpose of the Study:

• To investigate the relationship between spatial ability and performance in a non-visual computer-based navigation task.
• To determine if spatial ability predicts performance in interactive voice response systems across different age groups.

Main Methods:

• 196 participants aged 18-91 completed a simulated interactive voice response system task.
• Participants also underwent assessments of attention, working memory, and spatial abilities.
• Statistical analyses controlled for attention and working memory to isolate the effect of spatial ability.

Main Results:

• Age-related differences in spatial ability significantly predicted performance in the non-visual navigation task.
• This predictive relationship remained significant even after accounting for attention and working memory.
• Spatial ability emerged as a key factor influencing performance in non-visual computer interactions.

Conclusions:

• Spatial ability is crucial for effective performance in non-visual computer-based tasks.
• Findings suggest that spatial skills may underlie age-related disparities in technology adoption and use.
• Understanding these cognitive underpinnings can inform the design of more accessible technologies for all ages.
