The initial stage of visual selection is controlled by top-down task set: new ERP evidence
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.
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.
