现在有相当多的证据表明，当刺激在眼球跳动开始之前或之后闪现时，空间被压缩了。在这里，我们报告了两个连续的眼周视觉（而不是听觉）刺激之间的短时间间隔也被低估了，表明感知时间的压缩。我们更惊讶的是，在扫视前的一个关键时间间隔内，感知到的时间顺序一直是颠倒的。空间压缩和时间压缩的时间过程非常相似，这表明两者都是由一种共同的神经机制介导的，这可能与扫视时许多视觉区域的接受区发生的预测性变化有关。
There is now considerable evidence that space is compressed when stimuli are flashed shortly before or after the onset of a saccadic eye movement. Here we report that short intervals of time between two successive perisaccadic visual (but not auditory) stimuli are also underestimated, indicating a compression of perceived time. We were even more surprised that in a critical interval before saccades, perceived temporal order is consistently reversed. The very similar time courses of spatial and temporal compression suggest that both are mediated by a common neural mechanism, probably related to the predictive shifts that occur in receptive fields of many visual areas at the time of saccades.
