Visual Displays: The Continuing Investigations of the Highlighting Paradox

Previous research has suggested that making certain items visually salient, or highlighting, can speed performance in a visual search task. But designers of interfaces cannot always easily anticipate a user's target, and highlighting items other than the target can be associated with performance decrements. three experiments were performed which demonstrated that people's performance in a visual search task is differentially sensitive to highlighting's predictiveness of target location. That sensitivity depends upon the proportion of instances in which highlighting actually predicts target location. A cognitive model constructed using the ACT-R architecture inferred that people evaluate and adjust their visual search behavior at a very small level of the task. / pages 71-83 and 88-95 are missing from hard copy of text
