Abstract

In this digital era, the gap between the elderly and younger generations in their use of computer-based technology is wide, and many researchers in behavioural and social sciences, along with educators, welfare workers, and policy makers, are concerned about this disturbing phenomenon. However, it is not clear whether this discrepancy is due to a lack of previous access to information technology or declining mental ability in the course of aging. The purpose of this chapter is to consider the aged subpopulation’s needs and their ability to use digital technology from the perspectives of human cognitive architecture and the principles of instructional design guided by cognitive load theory. The authors focus on the following critical issues: a) the evolution and formation of human cognitive architecture, b) cognitive functioning as influenced by aging, c) compatibility between elderly people’s available mental resources and the cognitive requirements of digital equipment, and d) guidelines for human-computer multimedia interactions derived from the accumulated experimental evidence on effective instructional design and delivery.
