Overview of the eye-tracking task. The central stimulus was presented during a variable interval ranging from 800 to 1700 ms. In the gap condition (A), the central stimulus was extinguished before the onset of the peripheral stimulus during a period ranging from 120 to 200 ms. In the uncued overlap condition (B), the central stimulus remained on screen after the onset of the peripheral stimulus. In the cued overlap condition (C), auditory alerting cues were presented at variable time intervals ranging between 500 and 0 ms before the onset of the peripheral stimulus on 50% of the overlap trials. Participants completed 60 trials (20 gap, 20 uncued overlap, 20 cued gap).
