Yeshurun and Levy (2003) [Transient spatial attention degrades temporal resolution. Psychological Science, 14, 225 -231.] have suggested that visual attention enhances the activation of the parvocellular system and thus delays the perceived offset of a stimulus. We tested this assumption in a spatial cueing paradigm in which participants responded to stimulus offset. Consistent with this assumption, offset reaction time (RT) was prolonged for attended compared to unattended stimuli. For onset RT, however, we confirmed the well-known spatial cueing effect that attention speeds up the detection of stimulus onset. The results provide direct evidence for the proposal made by Yeshurun and Levy.
耶舒伦和利维（2003年）[《瞬时空间注意会降低时间分辨率。心理科学》，第14卷，第225 - 231页]提出，视觉注意会增强小细胞系统的激活，从而延迟对刺激的感知消失。我们在一个空间线索范式中对这一假设进行了测试，在该范式中参与者对刺激消失做出反应。与这一假设一致，与未被注意的刺激相比，被注意刺激的消失反应时（RT）延长了。然而，对于刺激开始的反应时，我们证实了众所周知的空间线索效应，即注意会加快对刺激开始的检测。这些结果为耶舒伦和利维提出的观点提供了直接证据。
