Models of overt attention

Formal models of overt attention have played an important role in motivating and interpreting studies of visual search and other tasks. This chapter briefly summarizes some general principles of attention, some general distinctions between models of overt attention, and some examples of existing models of overt attention in visual search, reading, free viewing, and interactive behaviors. Although many of these models have provided new insight into the factors that contribute to task performance, many are still in a formative stage. In the future, the most useful models will likely be those that take images as input, produce eye movements and decisions as output, apply to well-defined tasks, and explicitly represent the variation in early visual processing across the visual field.
