Blink and you won't miss it: The preview benefit in visual marking survives internally generated eyeblinks

摘要

People are able to ignore old (previewed) stimuli in order to prioritize the processing of newly appearing items-the preview benefit (D. G. Watson & G. W. Humphreys, 1997, "Visual marking: Prioritizing selection for new objects by top-down attentional inhibition of old objects," Psychological Review, Vol. 104, pp. 90-122). According to the inhibitory visual marking account, this is achieved by the top-down and capacity-limited inhibition of old stimuli already in the field, which leads to a selection advantage for new items when they appear. In contrast, according to the abrupt luminance onset account (M. Donk & J. Theeuwes, 2001, "Visual marking beside the mark: Prioritizing selection by abrupt onsets," Perception & Psychophysics, Vol. 63, pp. 891-900), new items capture attention automatically simply because they generate luminance onset signals. Here, we demonstrate that new items can be partially prioritized over old items even when they appear during an eyeblink and so have no unique luminance transients associated with their appearance. Overall, the findings suggest that both the inhibition of old items and attention capture by luminance changes contribute to time-based selection.
