我们的视觉系统在刺激消失后会短暂地保留一点痕迹。这种现象被称为图标记忆，其内容被认为与随后的视觉输入在时间上整合在一起，从而产生单一的合成表征。然而，关于象征性记忆和随后的视觉输入之间的时间整合问题，几乎没有达成共识。在这里，我们表明，图标记忆修改其内容取决于新产生的具有特定时间特征的单一表征的配置。在波根多夫错觉中，两个共线线段被一个中间的矩形视为非共线，当在线段呈现之前的50 ms到呈现线段之后的200 ms的时段内呈现该矩形时，观察到了该错觉。当矩形出现在线段后约100到150 ms时，错觉最为明显。此外，这种错觉是在运动对象的中心观察到的，但只有当线段呈现在矩形之前时才能观察到。这些结果表明，象征性记忆的内容在以时间锁定的方式被转换为意识知觉之前，容易受到后续视觉输入的调制影响，无论是在视网膜还是在非视网膜、以客体为中心的参照系中。
Our visual system briefly retains a trace of a stimulus after it disappears. This phenomenon is known as iconic memory and its contents are thought to be temporally integrated with subsequent visual inputs to produce a single composite representation. However, there is little consensus on the temporal integration between iconic memory and subsequent visual inputs. Here, we show that iconic memory revises its contents depending upon the configuration of the newly produced single representation with particular temporal characteristics. The Poggendorff illusion, in which two collinear line segments are perceived as non-collinear by an intervening rectangle, was observed when the rectangle was presented during a period spanning from 50 ms before to 200 ms after the presentation of the line segments. The illusion was most prominent when the rectangle was presented approximately 100 to 150 ms after the line segments. Furthermore, the illusion was observed at the center of a moving object, but only when the line segments were presented before the rectangle. These results indicate that the contents of iconic memory are susceptible to the modulatory influence of subsequent visual inputs before being translated into conscious perception in a time-locked manner both in retinotopic and non-retinotopic, object-centered frames of reference.
