| Abstract: | Recognition latency for reporting which of two possible target letters was present in an otherwise empty field was measured in conditions in which distance, but not direction, relative to the fixation point was validly cued, invalidly cued, or uncued in advance. The cues indicated that the letter could occur either just inside or outside of a circle of one degree radius centered on the fixation point. The results indicated marginally significant benefits for valid cues and significant costs for invalid cues for distance from fixation relative to the no-cue control condition. The results are consistent with a model that allows attention to be distributed over broad regions of foveal and parafoveal vision, rather than necessarily being restricted to specific foci or narrow regions. |
