When a Gabor moves in one direction in the visual periphery while its internal texture moves in the orthogonal direction, its perceived direction can deviate from its physical direction by as much as 45° or more. Lisi et al. showed that immediate saccades go to the physical location of double-drift targets, whereas delayed saccades primarily go to their perceived locations. Here, we investigated whether the apparent motion seen from the offset of a double-drift stimulus to the onset of a later target probe originates from the perceived or physical location of the double-drift stimulus. We find that apparent motion proceeds away from the perceived position of the double-drift stimulus at all temporal delays. This suggests that apparent motion is computed in perceptual rather than retinotopic coordinates.

表观运动是在感知坐标中计算的


当 Gabor 在视觉外围沿一个方向移动而其内部纹理沿正交方向移动时，其感知方向可能会偏离其物理方向多达 45° 或更多。丽丝等人。结果表明，立即扫视会前往双漂移目标的物理位置，而延迟扫视主要会前往其感知位置。在这里，我们研究了从双漂移刺激的偏移到稍后目标探针的开始所看到的表观运动是否源自双漂移刺激的感知或物理位置。我们发现，在所有时间延迟下，表观运动都远离双漂移刺激的感知位置。这表明视运动是在知觉坐标而不是视网膜专题坐标中计算的。
