| Abstract: | Describes 2 experiments in which visual and/or auditory location precues preceded visual or auditory targets. 30 observers were required to judge the location of the targets. Conditions were such that involuntary, stimulus-driven (SD) attention shifts were the only ones likely to occur and give rise to cueing effects. It was found that visual precues affected response time to localize both visual targets and auditory targets, but auditory precues affected only the time to localize auditory targets. Moreover, when visual and auditory cues conflicted, visual cues dominated in the visual task but were dominated by auditory cues in the auditory task. Results suggest that involuntary SD attention shifts might be controlled by a modality-specific mechanism for visual tasks, whereas SD shifts of auditory attention are controlled by a supramodal mechanism.
