The spatiotemporal dynamics of visual-spatial attention
pp. 51-66
Abstract
The vast majority of research on visual-spatial attention has examined the allocation of attention to locations away from the point of fixation, tacitly assuming that we frequently detect, identify, and act upon objects that we have not fixated. In natural visually guided behavior, however, this does not appear to be how attention operates. Instead, shifts of attention away from fixation are generally used to find regions that are likely to contain useful information and are therefore good targets for eye movements. Once the eyes have been shifted to a location, it is necessary to adjust the size of the attended region around fixation to encompass the fixated object and filter out surrounding objects, a role of attention that has received little empirical investigation. This chapter reviews evidence for the role of attention in finding appropriate saccade targets and discusses the largely unstudied role of attention in shrinking or expanding around the currently fixated object. The ability to dynamically adjust these processes depending on the nature of the current visual input is emphasized.
