Visual search. Attention.

Abstract

Discusses visual search tasks where the object is visible in the current field of view. The author discusses paradigmatic issues, such as accuracy methods, interpretation of search results, and the description of search performance. The author next describes the properties of preattentive processing, the processing of stimuli that occurs before attention is deployed to an item in a search task. The author then discusses the use of preattentive information by subsequent processes, including stimulus-driven and user-driven processes.
