title: The role of salience in localized attentional interference.
abstract: Observers were cued to attend to two discs from an array and made a discrimination of a target presented within one of the discs. In Experiments 1 and 2, the relative attentional salience of the two attended items was manipulated via the cues (size changes in Experiment 1; size and color changes in Experiment 2). In Experiment 3, the relative salience was manipulated via the luminance contrast of the items themselves. In Experiment 4, relative attentional salience was controlled through a probability manipulation. In all experiments, target performance improved with the relative salience of the target, as well as with increased spatial separation between the two items. This localized interference between cued items varied with visual field. Results are discussed in the context of competition-based models of attentional selection.
