Sage Journals: Discover world-class research

Abstract

The purpose of this investigation was to determine the effects of a person's cognitive style and the presence of emergent features in displays on performance in information integration and focused attention tasks. Cognitive style was assessed using Kagan's Matching Familiar Figures Test and performance was measured for each task type. It was predicted that when task demands required the observer to integrate information from different display locations (integrated task), impulsives would perform better than reflectives. Conversely, when the observer had to attend to single elements (focused task), reflectives would be better than impulsives. The display configured with an emergent feature was hypothesized to produce fewer errors and shorter response times for both focused and integrated tasks. Results showed that both tasks were aided by the configural design, eliciting shorter response times, and that this was true regardless of cognitive style. Implications of the results for display design are discussed.
