Complex Decision Support For Older Adults: Effects Of Information Visualization On Decision Performance, Margaux Price Dec 2010

Complex Decision Support For Older Adults: Effects Of Information Visualization On Decision Performance, Margaux Price

All Theses

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; …


A Multilevel Model Of Minority Opinion Expression And Team Decision-Making Effectiveness, Guihyun Grace Park, Richard D. Deshon Sep 2010

A Multilevel Model Of Minority Opinion Expression And Team Decision-Making Effectiveness, Guihyun Grace Park, Richard D. Deshon

Research Collection School of Social Sciences

The consideration of minority opinions when making team decisions is an important factor that contributes to team effectiveness. A multilevel model of minority opinion influence in decision-making teams is developed to address the conditions that relate to adequate consideration of minority opinions. Using a sample of 57 teams working on a simulated airport security-screening task, we demonstrate that team learning goal orientation influences the confidence of minority opinion holders and team discussion. Team discussion, in turn, relates to minority influence, greater decision quality, and team satisfaction. Implications for managing decision-making teams in organizations are discussed.


So Many Choices, So Little Time: Religiosity And The Stress Of Making Decisions, Joshua David Boeke Aug 2010

So Many Choices, So Little Time: Religiosity And The Stress Of Making Decisions, Joshua David Boeke

Undergraduate Honors Thesis Collection

Numerous studies have appeared in the literature demonstrating that religiosity and mental health are positively related. However, although investigators have identified several variables that partially mediate the effects of religiosity on mental health, much of this relationship remains unexplained. The goal of this survey study was to examine to what extent religious individuals experience better mental health outcomes because they experience less stress when making decisions. Specifically, this study evaluated whether religious individuals reduce the number of decision alternatives they consider when making decisions, which in turn should make decision making easier and reduce decision-making stress. Participants were asked to …


Hidden Consequences Of The Group Serving Bias: Causal Attributions And The Quality Of Group Decision Making, Jack Goncalo, Michelle M. Duguid May 2010

Hidden Consequences Of The Group Serving Bias: Causal Attributions And The Quality Of Group Decision Making, Jack Goncalo, Michelle M. Duguid

Jack Goncalo

A long stream of research in attribution theory suggests that groups are biased toward attributing their success to factors that are internal to their group. However, the existing research has confounded two types of attributions that are both internal to the group, but theoretically distinct: (1) Attributions that differentiate between the contributions made by each individual group member and (2) attributions that focus on the group as a whole. This dichotomy is important because, drawing on theories of social influence, we predict that different types of attributions will have different consequences for the quality of group decision making. In experiment …


Resolving Incomparability, David Pinkowski Jan 2010

Resolving Incomparability, David Pinkowski

Legacy Theses & Dissertations (2009 - 2024)

When confronted with an important choice between two very different options, an agent often will be at a loss as to how to decide between them. This is often true even if the agent has a good understanding of the pros and cons of each option, and even if she is committed to something like "the best overall decision for me." One way to analyze this situation is to assert that the options are incomparable for the agent. Incomparability arises when, for two options, it seems that one is neither better nor worse than, nor equal to, the other. If …


A Multiple Cue Threshold Learning Model Of Selection And Detection : Balancing Judgmental Accuracy With Threshold Learning, April M. Roggio Jan 2010

A Multiple Cue Threshold Learning Model Of Selection And Detection : Balancing Judgmental Accuracy With Threshold Learning, April M. Roggio

Legacy Theses & Dissertations (2009 - 2024)

Selection and detection problems represent some of the most challenging decision making tasks, especially in the fields of health and medicine. In a population of pregnant women, who is a candidate for a cesarean delivery? Does this mammogram indicate the presence of cancer? Should antibiotics be prescribed for this illness? We must judge
