This study was designed to explore the effects of transient attention-the stimulus-driven component of spatial attention - on the perceived duration of a brief visual event. Observers had to compare the duration of two disks presented successively within a single trial. The disks' location and duration varied independently. One of these disks, the "attended disk", was preceded by an attentional cue indicating the disk's location, attracting transient attention in advanced to the disk location. This attentional cue was either a typical onset cue (Experiments 1, 2, and 4) or a singleton cue (Experiment 3) that minimized the differences between the cues. The other disk, the "neutral disk", was cued with a neutral cue that did not convey information regarding the disk location. We found that the attraction of transient attention to the location of the attended disk prolonged its perceived duration, but only when compared to brief nonattend stimuli.
