Cognitive style and field knowledge in complex design problem solving: A comparative case study of design decision support systems

Other Titles

Abstract

Cognitive differences in how people perceive and process information have been broadly studied in the fields of education and psychology. Previous findings show that comprehension is optimized when information presentation aligns with the cognitive abilities and preferences of an individual. On the other hand, the possession of field knowledge has also been studied to influence learning outcome and perception. This paper aims to understand the effects of individual’s information processing styles and field knowledge on design decision-making, specifically focusing on designer learning and user experience. Two distinct decision support systems interfaces were developed to better examine the effect using a mixed model design. A total of 48 college students participated in the quantitative study and interacted with the two different interfaces of a satellite design system in a randomized order. Then a representative subset of data samples was selected for further qualitative analysis. Results show significant impacts of field knowledge and visual processing style on learning and user experience as well as behavioral differences between different user groups. Potential interaction effects with the design support system interface type and cognitive styles were also observed.
