Older adults are faced with complex decision tasks that impose high working memory demands. A representative task is choosing a prescription drug plan from a multitude of options that must be evaluated along many factors. The combined effect of the quantity of complex information, and reduced working memory capacity puts older adults at a disadvantage. However, research with younger adults suggests that the working memory burden of decision tasks can be reduced using well-designed, graphical decision aids (i.e., environmental supports). The current study examined the use of environmental supports to support complex decision-making for older adults. Two experiments were conducted; …

Sixty-one adults between the ages of 54 and 88 (52% female) participated in a second phase in which neuropsychological tasks were administered to assess three cognitive domains; memory, learning, and executive functioning. …
