Abstract : This report describes achievement in four areas: (1) Guided Search 3.0 (GS3) is the third generation of the Guided Search model of visual search behavior. It models new visual search data and proposes a relationship between covert deployment of attention and overt eye movements. (2) Research documents the effect of eccentricity in visual search, shows the interaction of those effects with other visual and non-visual loads, and incorporates eccentricity effects into GS3. (3) A retrospective analysis of 2500 search sessions provides an unprecedented statistical picture of human search behavior. (4) Research shows that published inferences based on individual differences in search performance must be evaluated with great caution. These differences prove to be statistically unreliable. Nevertheless, with proper methods, it is possible to find reliable individual differences in visual search.
