通过三个实验研究了对象表征在对象替代掩蔽（OSM）中的作用。当一个非常稀疏的掩模与目标刺激同时出现时，目标首先偏移，使掩模在显示中停留一段时间，就会发生OSM。结果证实了先前的说法，即OSM存在一个可隔离的对象级组件，并表明如果在偏移之前，目标可以表示为与掩模不同的对象，则可以保护目标免受OSM的影响。当掩模以滑动过目标（实验1）、独立于目标的抖动（实验2）或与目标不同的颜色（实验3）呈现时，OSM被减少或消除。这表明OSM反映了基本的更新过程，允许感知对象身份的连续性而不是变化。
Three experiments were conducted to investigate the role of object representations in object substitution masking (OSM). OSM occurs when a very sparse mask is presented simultaneously with a target stimulus and the target offsets first, leaving the mask to linger in the display for some time. Results confirm earlier claims that there is an isolatable object-level component to OSM and indicate that a target can be protected from OSM if, prior to offsetting, it can be represented as a distinct object from the mask. When the mask was presented as sliding past the target (Experiment 1), as jiggling independently of the target (Experiment 2), or in a different color from the target (Experiment 3), OSM was reduced or eliminated. This suggests that OSM reflects basic updating processes that allow the perception of continuity of object identity over change.
