当视觉目标短暂地出现在包含视觉运动信息的显示器中时，目标的感知位置沿着其运动方向向前沿着被错误定位。这种现象被认为是由目标的瞬态起始信号和运动信息之间的相互作用引起的。然而，虽然瞬态起始和偏移信号对于我们的感知意识的建立是重要的，但是还没有研究瞬态偏移信号是否对于目标误定位也是有效的。在这里，我们表明，在感知位置发生的变化，包含一个时间上短暂的偏移信号在一个视运动（AM）显示的视觉目标。首先，水平AM，我们发现，虚幻的运动被认为是当一个静态的目标瞬时和反复眨眼在一个固定的位置。错觉运动的感知方向与AM刺激的方向相反。此外，我们证实，虚幻的运动经常被认为是当（1）偏心的目标是较大的，（2）偏移持续时间较长，（3）平滑AM被认为。错觉运动，除非AM刺激后的偏移信号，而错觉运动仍然发生时，AM刺激消失之前的偏移信号。此外，我们发现，误定位的目标的感知位置实际上发生在一个方向相反的AM。这些研究结果表明，一个瞬态偏移信号可以触发感知错误定位的静态视觉刺激的运动信息的相互作用，在postdictive的方式。
When a visual target briefly appears in a display containing visual motion information, the perceived position of the target is mislocalized forward along its direction of motion. This phenomenon is assumed to be caused by the interaction between the transient onset signal of the target and motion information. However, while transient onset and offset signals are important for the establishment of our perceptual awareness, it has not been examined whether transient offset signals could be also effective for target mislocalization. Here, we demonstrate that shifts in perceived position occurred for a visual target containing a temporally transient offset signal in an apparent motion (AM) display. First, with horizontal AM, we found that illusory motion was perceived when a static target transiently and repeatedly blinked at a fixed position. The perceived direction of the illusory motion was in counter-phase with that of the AM stimuli. Further, we confirmed that illusory motion was frequently perceived when (1) the eccentricity of the target was larger, (2) offset duration was longer, and (3) smoother AM was perceived. Illusory motion was not perceived unless AM stimuli were presented after the offset signal, while illusory motion still occurred when the AM stimuli disappeared before the offset signal. In addition, we found that mislocalization of the target’s perceived position actually occurred in a direction opposite to AM. These findings suggest that a transient offset signal could trigger perceptual mislocalization of static visual stimuli by interacting with motion information in a postdictive manner.
