The object updating hypothesis of object substitution masking proposes that the phenomenon arises when the visual system fails to individuate target and mask at the level of object token representations. This hypothesis is tested in two experiments using modifications of the dot mask paradigm developed by Lleras and Moore (2003). Target-mask individuation is manipulated by the presentation of additional display items that influence the linking apparent motion seen between a target and a spatially separated mask (Experiment 1), and by the use of placeholders that maintain the target object's presence during mask presentation (Experiment 2). Results in both cases are consistent with the updating hypothesis in showing significantly reduced masking when the conditions promoted target-mask individuation. However, in both experiments, some masking was still present under conditions of individuation, an effect we attribute to attentional capture by the mask.
客体替换掩蔽的客体更新假说认为，当视觉系统无法在客体标记表示的层面上区分目标和掩蔽时，就会出现这种现象。本假说在两个实验中得到了检验，实验使用了由 Lleras 和 Moore（2003）开发的点掩蔽范式的修改版本。通过呈现额外的显示项目来操纵目标-掩蔽的区分，这些项目会影响到在目标和空间分离的掩蔽之间看到的连接似动（实验 1），并通过使用占位符在掩蔽呈现期间保持目标物体的存在（实验 2）。这两种情况下的结果都与更新假说一致，表明当条件促进目标-掩蔽区分时，掩蔽显著减少。然而，在两种情况下，在区分条件下仍存在一些掩蔽，我们将这种效应归因于掩蔽的注意力捕获。
