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.
人们能够忽略旧的(预视)刺激,以便优先处理新出现的项目——这就是预视效益(D.G.沃森和 G.W.汉弗莱斯,1997,“视觉标记:通过自上而下的对旧物体的注意抑制来优先选择新物体”,《心理评论》,第 104 卷,第 90-122 页)。根据抑制性视觉标记理论,这是通过已经在视野中的旧刺激的自上而下的、容量有限的抑制来实现的,这导致新出现的项目具有选择优势。相比之下,根据突然的亮度起始理论(M.唐克和 J.特乌韦斯,2001,“标记旁的视觉标记:通过突然的起始来优先选择”,《感知与心理物理学》,第 63 卷,第 891-900 页),新的项目会自动吸引注意力,仅仅是因为它们产生了亮度起始信号。在这里,我们证明,即使新的项目出现在眨眼期间,并且没有与它们的出现相关的独特的亮度瞬变,它们也可以部分优先于旧的项目。总的来说,这些发现表明,旧项目的抑制和亮度变化引起的注意力捕获都有助于基于时间的选择。
