1	The Effects of Alternative Presentation Formats on Biases and Heuristics in Human Decision Making Van Dyke, Thomas P. (Thomas Peter) 05 1900 (has links) The purpose of this research was to determine whether changes in the presentation format of items in a computer display could be used to alter the impact of specific cognitive biases, and to add to the knowledge needed to construct theory-based guidelines for output design. The problem motivating this study is twofold. The first part of the problem is the sub-optimal decision making caused by the use of heuristics and their associated cognitive biases. The second part of the problem is the lack of a theoretical basis to guide the design of information presentation formats to counter the effects of such biases. An availability model of the impact of changes in presentation format on biases and heuristics was constructed based on the findings of a literature review. A six-part laboratory experiment was conducted utilizing a sample of 205 student subjects from the college of business. The independent variable was presentation format which was manipulated by altering the visual salience or visual recency of items of information in a visual computer display. The dependent variables included recall, perceived importance, and the subjects' responses to three judgment tasks. The results clearly demonstrate that changes in presentation format can be used to alter the impact of cognitive biases on human decision making. The results also provide support for the availability model, with the exception of the proposed influence of learning style. Learning style was found to have no significant impact on decision making whether alone or in combination with changes in presentation format. The results of this investigation demonstrate that by using our knowledge of cognitive processes (e.g., the visual salience effect, the visual recency effect, and the availability heuristic), presentation formats can be altered in order to moderate the effects of certain biases and heuristics in human decision making. An understanding of these results may be useful in improving DSS design. Business presentations. Computer graphics. Decision making. Prejudices.

2	Communicating science : developing an exhibit with scientists and educators Lemagie, Emily 28 October 2011 (has links) Outreach is a small, but significant component to modern research. Developing an exhibit for public display can be an effective way to communicate science to broad audiences, although it may be a less familiar method to scientists than writing papers or giving presentations. I outline the process of developing an interactive exhibit for outreach, and evaluate and discuss the effectiveness of a computer exhibit designed to communicate estuary currents and scientific modeling using Olympia Oyster restoration in the Yaquina Bay estuary as a theme. I summarize the results of this project in three primary recommendations: 1) exhibit developers should be deliberate in the decision to use a computer and only select this media if it is determined to be the best for communicating exhibit learning outcomes, 2) the design of visualizations to convey research results should be carefully modified from their scientific forms to best meet the exhibit learning outcomes and expectations of the exhibit audience, and 3) scientists should play an integral role in the development of scientific content-based exhibits, but their expertise, and the range of expertise from other members of the exhibit development team, should be strategically utilized. / Graduation date: 2012 Exhibit Exhibit Development Exhibit Design Education Marine Education Marine Interpretation Science Interpretation Informal Science Environmental Interpretation Environmental Outreach Science Education Communicating Science Estuary Interpretation Communication Outreach Science Outreach Free-Choice Learning Informal Education Informal Science Estuary Education Museum Exhibit Interactive Kiosk Computer Exhibit Computer Interface Interactive Touchscreen Kiosk Marine Science Exhibit Computer Display Interactive Exhibit Interactive Visualization Current Simulation Scientific Model Numerical Model Estuary Science Visitor Center Marine Science Center Visitor Behavior Museum Hatfield Marine Science Center Science Center Emily Lemagie Oregon Sea Grant Education Kiosk Educational Kiosk Computer Kiosk Science Communication Touchscreen Interface Backwards Design Tidulator Museum exhibits -- Oregon -- Newport Hatfield Marine Science Center
