In the flash-lag effect (FLE) a moving object is perceived ahead of a stationary stimulus flashed in spatial alignment. Several explanations have been proposed to account for the FLE and its dependence on a variety of psychophysical attributes. Here, we show that a simple feed-forward network reproduces the standard FLE and several related manifestations, such as its modulation by stimulus luminance, trajectory, priming, and spatial predictability. A minimal set of elements, based on plausible neuronal mechanisms, yields a unified account of these visual illusions and possibly other perceptual phenomena.
在闪光滞后效应（FLE）中，一个移动的物体被感知为在空间上对齐闪现的静止刺激之前。已经提出了几种解释来解释FLE及其对各种心理物理属性的依赖性。在这里，我们表明一个简单的前馈网络可以再现标准的FLE和几种相关表现，例如其受刺激亮度、轨迹、启动和空间可预测性的调制。基于合理的神经元机制的一组最小元素，对这些视觉错觉以及可能的其他感知现象给出了统一的解释。
