Information Visualization Techniques and Decision Style: The Effects in Decision Support Environments

The importance of individual characteristics has been emphasized in the human computer interaction and information visualization (IV) literature. However, decision style, which is recognized as one of the key individual cognitive differences that affects system success, has received little attention in these areas. This study aims to examine how decision style, IV techniques and task complexity affects decision performance and user preferences in a managerial decision support environment. The study adopted an experimental method, based on within-participants design approach. The results showed that there were significant differences in decision performance between IV techniques, individual differences and task. The results suggest that decision style moderates the relationship between IV techniques and performance. The findings have important implications for the DSS designers, and provide important research issues for future work. Keywords Decision Style, Information Visualization, D...
