Abstract

To make their system quickly usable, designers often build interfaces that reflect well-known manual activities. Demonstrates how undergraduates use their mental models for print encyclopedias to develop minimal proficiency with various electronic encyclopedias. Lower performance levels in the electronic systems are due to additional cognitive load required to adapt and develop mental models for the new systems. For the fact retrieval questions used in these relativley small data bases, the hypertext encyclopedia required less cognitive load than the 2 traditional Boolean-based systems. Adaptive designs that provide multiple system images are encouraged to support more comprehensive user understanding and more varied tasks
