Ansorge, Ulrich and Kiss, Monika and Worschech, Franziska and Eimer, Martin (2011) The initial stage of visual selection is controlled by top-down task set: new ERP evidence. Attention, Perception and Psychophysics 73 (1), pp. 113-122. ISSN 1943-3921.Full text not available from this repository.
Salient visual singleton stimuli produce spatial cueing effects indicative of attentional capture only when they match current task sets, suggesting that capture is subject to top-down control. However, such task-set contingent capture effects could be associated with the top-down controlled disengagement of attention from non-matching stimuli that follows their initial bottom-up salience-driven selection. Using the N2pc component as an event-related potential marker of attentional capture, we demonstrate that top-down task set already controls the initial rapid selection of salient visual singleton stimuli prior to any subsequent attentional disengagement. These findings provide new evidence for the primacy of top-down control over bottom-up salience in attentional capture.
