Previous research [Fisher, D. L., & Tan, K. C. (1989). Visual displays: The highlighting paradox. Human Factors, 31(1), 17–30] suggested that making certain items visually salient, or highlighting, can speed performance in visual search tasks. But interface designers cannot always anticipate users’ intended targets, and highlighting non-target items can lead to performance decrements. An experiment presented suggests that people attend to highlighting less than what an algebraic visual search model of highlighted displays [Fisher, D. L., Coury, B. G., Tengs, T. O., & Duffy, S. A. (1989). Minimizing the time to search visual displays: The role of highlighting. Human Factors, 31(2), 167–182] predicts. Users adjust their visual search strategies by probability-matching to their visual environment. An ACT-R [Anderson, J. R., Bothell, D., Byrne, M. D., Douglass, S., Lebiere, C., & Quin, Y. (2004). An integrated theory of the mind. Psychological Review, 111, 1036–1060] model reproduced the major effects of the experiment and suggests that learning in this task occurs at very small cognitive and time scales.
