Most of the studies in long-range apparent movement have been concerned with the psychophysical properties in central vision. However, apparent movement in peripheral vision is not clearly understood. This study focuses on the properties of the perception of apparent movement between central and peripheral vision. The results show that judgements of apparent movement in central vision indicate high performance at less than 4 degrees of spatial separation, and that judgements in peripheral vision indicate high performance at greater than 4 degrees. Evoked potentials associated with long-range apparent movement were also measured, and topographic maps were constructed to evaluate the active areas corresponding to visual apparent movement. The topographic maps show that the central regions are activated above 300 msec after the onset of the second apparent-movement stimulation. The results suggest that visual apparent movement occurs in the visual association area, or at higher levels in the central nervous system.
大多数关于长程表观运动的研究都集中在中央视觉的心理物理学特性上。然而，人们对周边视觉中的表观运动还没有清晰的理解。本研究聚焦于中央视觉和周边视觉之间表观运动感知的特性。结果表明，中央视觉中表观运动的判断在空间分离小于4度时表现出高性能，而周边视觉中的判断在大于4度时表现出高性能。还测量了与长程表观运动相关的诱发电位，并构建了地形图以评估与视觉表观运动对应的活跃区域。地形图显示，在第二次表观运动刺激开始后300毫秒以上，中央区域被激活。结果表明，视觉表观运动发生在视觉联合区或中枢神经系统的更高水平。
