视觉估计亚秒持续时间的神经机制尚不清楚，但闪烁间隔的视周低估可能为这些机制的本质提供线索。在这里，我们发现，简单地降低闪光可见性，特别是瞬态信号的可见性，也会引起人类观察者类似的时间低估。我们的研究结果表明，弱瞬态反应不能触发对时间异步的适当检测，导致同时性的感知增加和明显的时间压缩。
The neural mechanisms underlying visual estimation of subsecond durations remain unknown, but perisaccadic underestimation of interflash intervals may provide a clue as to the nature of these mechanisms. Here we found that simply reducing the flash visibility, particularly the visibility of transient signals, induced similar time underestimation by human observers. Our results suggest that weak transient responses fail to trigger the proper detection of temporal asynchrony, leading to increased perception of simultaneity and apparent time compression.
