Effects of age‐related decline of visual attention, working memory and planning functions on use of IT‐equipment

Abstract

The effects of age-related decline of cognitive functions, such as visual attention, working memory and planning functions on use of IT-equipment were investigated. Older participants (n = 34; aged 65-73 years) were divided into two groups based on AIST-cognitive aging test (AIST-CAT) scores. They were then asked to purchase a reserved seat for the Japanese bullet train, using a ticket vending machine. The results showed that: (a) the decline in visual attention caused a disruption in searching for objects on the screen; (b) the decline in working memory interrupted maintaining subgoals; and (c) information related to subgoals; and the decline in planning function, interrupted constructing and maintaining a behavior sequence for operating a ticket vending machine. These results indicate that the age-related decline of cognitive functions is differentially related to problems with using IT-equipment.j pr_438 201..215Key words: cognitive aging, visual attention, working memory, planning function, usability for older adults.In the past decade much of the equipment we use in our daily life has become increasing dependent on computerized information technology (IT). Technology generally adds a variety of functions to basically simple equipment. For example, computerized televisions provide a greater variety of information than traditional televisions that receive only broadcast or cable programming. However, it is not necessarily the case that computerized equipment (referred to as IT-equipment) is easy to use for all people. This is particularly relevant with regard to older users. In fact, previous studies have reported that older adults experience a variety of difficulties in using

62‐3: Invited Paper: Human Interface Design in Transition from Automated Driving to Manual Driving

“…The driving style and skill cannot be changed temporarily, and they are promoted by driving experience (exposure time in real road and traffic conditions) and education / training. The physical and cognitive characteristics are mainly influenced by the driver's age [7]. The dynamic factors are driver's physical and mental states, including attentional resource allocation toward the dynamic driving task.…”

Adaptive problem solving

“…That is, people vary on many of these cognitive components, notably executive control, working memory capacity, monitoring of attention to relevant information, and speed and accuracy of perceptual-motor-cognitive operations (Baddeley, 2007;Demetriou, Mouyi and Spanoudis, 2008;John and Kieras, 1996;Wiley and Jarosz, 2012;Wüstenberg et al, 2015). Some of these cognitive constraints may systematically vary by age and culture (Suto and Kumada, 2010).…”

Editorial: Special issue on cognitive aging, safety, and quality of life

“…For instance, Suto's paper attempts to directly link the decline of some aspects of cognitive functioning with aging to the barriers and failures that people experience when trying to use some equipment (Suto & Kumada, 2010). Similarly, but from the perspective of practitioners in cognitive engineering, Hara's paper demonstrates that the kinds of problems older people have in using IT equipment can be solved by changing the informational designs of the equipment by drawing on the analyses of cognitive psychology (Hara & Kashimura, 2010).…”
