Thesis title: Complex Decision Support for Older Adults:  Effects of Information Visualization on Decision Performance

Abstract: 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 examines the use of environmental supports to support complex decision-making for older adults. Two experiments are proposed; experiment 1 will assess information visualizations that reduce the working memory demands of the task. The second experiment will validate the efficacy of the information visualization in an older adult group. Findings from this study will be used to make recommendations for visualizations as complex decision support systems.
