一条中央沙洲与两条侧翼沙洲交替出现，可导致中央沙洲消失。最近有人提出，这种掩蔽效应可以解释为对象介导的更新：从中央酒吧的信息被整合到两侧的代表，导致不仅消失的中央酒吧作为一个单独的对象，但也感知的侧翼在其真实的位置和中央酒吧的位置之间的明显运动。这一解释表明，中心杆的可见性应该取决于那些影响物体表征的构建和维护的因素。因此，只要中间条和侧翼之间的时间间隔足以解释一个物体从一个位置移动到另一个可能位置的场景，那么中间条和侧翼之间的分离不应影响可见性。我们发现，如果中央棒和侧翼棒之间的时间间隔既不太短也不太长，即使在大的分离，中央棒也变得不可见。这些发现是不一致的传统帐户的循环侧掩蔽显示在当地的抑制机制。
A central bar repeatedly presented in alternation with two flanking bars can lead to the disappearance of the central bar. Recently it has been suggested that this masking effect could be explained by object-mediated updating: the information from the central bar is integrated into the representation of the flankers, leading not only to the disappearance of the central bar as a separate object, but also to the perception of the flankers in apparent motion between their real position and the position of the central bar. This account suggests that the visibility of the central bar should depend on the same factors as those that influence the construction and maintenance of object representations. Therefore separation between central bar and flankers should not influence visibility as long as the time interval between them is adequate to make an interpretation of the scene in terms of one object moving from one location to the other possible location. We found that if the time interval between the central bar and the flankers is neither too short nor too long, the central bar becomes invisible even at large separations. These findings are inconsistent with traditional accounts of the cycling lateral masking displays in terms of local inhibitory mechanisms.
