Goal-driven attentional capture by invisible colors: evidence from event-related potentials
Ansorge, Ulrich and Kiss, Monika and Eimer, Martin (2009) Goal-driven attentional capture by invisible colors: evidence from event-related potentials. Psychonomic Bulletin and Review 16 (4), pp. 648-653. ISSN 1069-9384.
We combined event-related brain potentials (ERPs) and behavioral measures to test whether subliminal visual stimuli can capture attention in a goal-dependent manner. Participants searched for visual targets defined by a specific color. Search displays served as metacontrast masks for preceding cue displays that contained one cue in the target color. Although this target-color cue was spatially uninformative, it produced behavioral spatial cuing effects and triggered an ERP correlate of attentional selection (i.e., the N2pc component). These results demonstrate that target-color cues captured attention, in spite of the fact that cue localization performance assessed in separate blocks was at chance level. We conclude that task-set contingent attentional capture is not restricted to supraliminal stimuli, but is also elicited by visual events that are not consciously perceived.
