Recently, Yeshurun and Levy (Psychol Sci 14:225-231, 2003) have provided evidence for the notion that visual attention impairs the temporal resolution of the visual system. Specifically, the detection of a temporal gap within a visual stimulus was impaired when a cue directed attention towards the spatial location of the stimulus. As this negative cueing effect is important to constrain theories about visual attention, we further investigated this novel effect and assessed whether it truly reflects an attentional effect. Experiment 1 examines whether the negative cueing effect is due to local temporal interference, and Experiments 2 and 3 investigate whether it reflects a luminance confound. The complete pattern of results argues against these alternatives and thus further strengthens the conclusion of Yeshurun and Levy (Psychol Sci 14: 225-231, 2003).
最近，叶舒伦和利维（《心理科学》14:225 - 231，2003年）为视觉注意力会损害视觉系统的时间分辨率这一观点提供了证据。具体而言，当一个线索将注意力引向视觉刺激的空间位置时，对视觉刺激中时间间隔的检测就会受到损害。由于这种负面线索效应对于限制有关视觉注意力的理论很重要，我们进一步研究了这种新效应，并评估它是否真的反映了一种注意力效应。实验1检验负面线索效应是否是由于局部时间干扰引起的，实验2和实验3则研究它是否反映了亮度混淆。完整的结果模式反驳了这些替代解释，从而进一步强化了叶舒伦和利维（《心理科学》14: 225 - 231，2003年）的结论。
