神经对重复刺激的反应通常会减弱，这种效应被称为重复抑制。我们在这里展示了重复对主观持续时间的平行影响，即使刺激呈现得太快，无法进行明确的时间判断。当一个短暂的视觉刺激(例如，一个字母、一个单词、一个物体或一张脸)在不同的位置连续闪光时，由于视觉的持久性，几个刺激似乎同时出现--我们称之为扩散效应。关键的是，与每次闪光使用不同的刺激相比，重复闪光相同的刺激时同时出现的刺激更少，这表明视觉的持久性(因此主观持续时间)因可预测的刺激而收缩。这些短时间尺度的实验表明，主观持续时间是在意识前和内隐加工水平上计算的，从而改变了视觉场景的时间解释。此外，这些发现提出了一种新的、即时的重复抑制缺陷诊断测试，例如在精神分裂症中发现的缺陷。
Neural responses to a repeated stimulus typically diminish, an effect known as repetition suppression. We here demonstrate what appear to be parallel effects of repetition on subjective duration, even when stimuli are presented too rapidly for explicit temporal judgments. When a brief visual stimulus (e.g., a letter, word, object, or face) was serially flashed in different locations, several stimuli appeared to be present simultaneously due to persistence of vision—we term this the Proliferation Effect. Critically, fewer stimuli were perceived to be simultaneously present when the same stimulus was flashed repeatedly than when a different stimulus was used for each flash, indicating that persistence of vision (and hence subjective duration) shrinks for predictable stimuli. These short-timescale experiments demonstrate that subjective durations are computed at a preconscious and implicit level of processing, thereby changing the temporal interpretation of visual scenes. Further, these findings suggest a new, instant diagnostic test for deficits in repetition suppression, such as those found in schizophrenia.
