在闪滞错觉中，与灰对齐的运动物体被认为在运动方向上被偏移。灰烬。在“闪-拖”错觉中，a. ash在附近运动的方向上定位错误。在“闪跃”错觉中，移动物体（如颜色）外观的短暂变化在随后的运动方向上被错误定位。最后，在Frohlich错觉中，突然出现的运动物体的起始位置在随后的运动方向上是错误的。在一系列实验中，我们证明了对所有这些错觉的统一解释：感知定位受到查询触发后大约80毫秒内收集的运动信号的影响。这些演示排除了“延迟差异”和异步特征绑定模型，在这些模型中，对象出现在它们的实际位置，但在时间上没有对齐。相反，这里探索的错觉最好被理解为由运动信号引起的定位偏差。我们认为运动偏倚的存在是因为它允许视觉系统通过回顾性地“推动”物体更接近其真实的物理位置来解释神经处理延迟，我们提出了探索运动敏感神经元活动动态更新位置的神经机制的方向。
In the flash-lag illusion, a moving object aligned with a. ash is perceived to be offset in the direction of motion following the. ash. In the "flash-drag'' illusion, a. ash is mislocalized in the direction of nearby motion. In the "flash-jump'' illusion, a transient change in the appearance of a moving object ( e. g., color) is mislocalized in the direction of subsequent motion. Finally, in the Frohlich illusion, the starting position of a suddenly appearing moving object is mislocalized in the direction of the subsequent motion. We demonstrate, in a series of experiments, a unified explanation for all these illusions: Perceptual localization is influenced by motion signals collected over similar to 80 ms after a query is triggered. These demonstrations rule out "latency difference'' and asynchronous feature binding models, in which objects appear in their real positions but misaligned in time. Instead, the illusions explored here are best understood as biases in localization caused by motion signals. We suggest that motion biasing exists because it allows the visual system to account for neural processing delays by retrospectively "pushing'' an object closer to its true physical location, and we propose directions for exploring the neural mechanisms underlying the dynamic updating of location by the activity of motion-sensitive neurons.
