Attentional capture by masked colour singletons
Ansorge, Ulrich and Horstmann, G. and Worschech, Franziska (2010) Attentional capture by masked colour singletons. Vision Research 50 (19), pp. 2015-2027. ISSN 0042-6989.
We tested under which conditions a colour singleton of which an observer is unaware captures attention. To prevent visual awareness of the colour singleton, we used backward masking. We find that a masked colour singleton cue captures attention if it matches the observer’s goal to search for target colours but not if it is task-irrelevant. This is also reflected in event-related potentials to the visible target: the masked goal-matching cue elicits an attentional potential (N2pc) in a target search task. By contrast, a non-matching but equally strong masked colour singleton cue failed to elicit a capture effect and an N2pc. Results are discussed with regard to currently pertaining conceptions of attentional capture by colour singletons.
