由于物体和自运动在自然视觉条件下是普遍存在的，因此理解人类视觉系统如何实现对运动物体的相对清晰的感知是视觉感知中的基本问题。几项研究表明，在正常观看条件下，短暂呈现的静止刺激的可见持续时间约为120 ms。基于这种可见光的持续时间，我们可以预期移动的物体看起来非常模糊。然而，在人类视觉中，运动中的对象通常看起来相对清晰和清晰。我们认为，在动态观看的形式清晰度是通过掩蔽，感知分组和运动计算之间的协同作用，在retinotopic和非retinotopic表示。我们还认为，在掩蔽观察到的解离是必不可少的创造和维持这种协同作用。
Because object and self-motion are ubiquitous in natural viewing conditions, understanding how the human visual system achieves a relatively clear perception for moving objects is a fundamental problem in visual perception. Several studies have shown that the visible persistence of a briefly presented stationary stimulus is approximately 120 ms under normal viewing conditions. Based on this duration of visible persistence, we would expect moving objects to appear highly blurred. However, in human vision, objects in motion typically appear relatively sharp and clear. We suggest that clarity of form in dynamic viewing is achieved by a synergy between masking, perceptual grouping, and motion computation across retinotopic and non-retinotopic representations. We also argue that dissociations observed in masking are essential to create and maintain this synergy.
