Abstract

Visual sensitivity can be heightened in the vicinity of an appropriate pre-cue. Experiments with multiple, non-informative pre-cues suggest that this facilitation should not be attributed to focal attention. The number of simultaneously appearing pre-cues seems to be irrelevant; contrast thresholds are lowest for targets that appear in a pre-cued position. Here, we report that pre-cues become less effective when they and the target are delivered to different eyes. We conclude that the mechanism responsible for heightened sensitivity has largely monocular input.
