Abstract

With the exponential growth of Internet technology, the notion of users' cognition when navigating such a vast information space has gained prominence. Studies suggest that metaphors can serve as effective tools to scaffold users' mental modeling processes. However, how users conceive of the metaphorical aid (as opposed to simply how they perceive it) remains questionable. Cognitive style, or the user's preferred way of information processing, has thus been posited as a possible factor affecting the success of the metaphorical approach in a hypermedia environment. This study explores the effects of visual metaphors and cognitive styles on users' learning performances in terms of structural knowledge and feelings of disorientation. The results indicate that a visual metaphor could improve the quality of mental formation, yet simultaneously increase users' mental load during navigation. In addition, cognitive style is a crucial factor that can significantly affect users' learning performance.
