Interactive Choice

This talk at the Judgment & Decision Making Conference 2008 explores the research need for creating solutions and dynamic decisions in web-based experiments. The focus is on generating web-pages "on the fly", without using AI, through a predefined process and format/style. The cost/benefit trade-off and alternative methods of presenting stimuli are discussed.

Building Interactive Choice • Focus of talk • Research need → application • Research question: creating solutions, dynamic decisions • Web-pages generated “on the fly” • Not AI • Predefined process and format/style • Server application • Cost/benefit trade off • “If you can dream it, you can build it”(Weninger, 2005)
