每当视觉流突然受到眼球运动、眨眼、遮蔽或闪光的干扰时，视觉系统就需要检索当前目标的新位置并重建事件的时间以跨越中断。此过程可能会引入位置和计时误差。我们在这里报告，当干扰是由眼球运动（众所周知）或正如我们现在展示的掩蔽引起的时，在三种不同范式的人类受试者中都会出现非常相似的错误。我们认为，眼球运动对位置和时间、空间和时间压缩以及位移的扫视抑制的特征影响是中断和随后重新连接的结果，并且当视觉输入被屏蔽而没有任何眼球运动时也可以看到。我们的数据表明，压缩和抑制效应不仅仅是眼部运动活动的产物，而且可以是对应过程的属性，该对应过程将视觉输入中断中的感兴趣目标联系起来，无论其来源是什么。
Whenever the visual stream is abruptly disturbed by eye movements, blinks, masks, or flashes of light, the visual system needs to retrieve the new locations of current targets and to reconstruct the timing of events to straddle the interruption. This process may introduce position and timing errors. We here report that very similar errors are seen in human subjects across three different paradigms when disturbances are caused by either eye movements, as is well known, or, as we now show, masking. We suggest that the characteristic effects of eye movements on position and time, spatial and temporal compression and saccadic suppression of displacement, are consequences of the interruption and the subsequent reconnection and are seen also when visual input is masked without any eye movements. Our data show that compression and suppression effects are not solely a product of ocular motor activity but instead can be properties of a correspondence process that links the targets of interest across interruptions in visual input, no matter what their source.
