Dissertation Abstract
One of the problems studied in HCI research is the design of interfaces that improve the speed of information retrieval. Based on research findings in the areas of information systems and cognitive psychology, this dissertation proposes that information processing can be improved by designing interfaces supporting associative cognitive processing. The research is based on dual-processing theories which collectively posit that some information is processed using a fast information-processing mode (associative processing), while other types of information are processed using a slow information processing mode (symbolic processing). The proposed model will be validated using a series of laboratory experiments. Results of study 1 suggest that color can be successfully used in interface design to increase information retrieval performance speed. Study 2 is set to explore the usefulness of associations for information processing under time pressure in emergency response systems. Future studies are proposed to examine the use of personalization to further enhance the performance benefits obtained through associative processing.
