Mitroff等人的研究发现了OSPBs效应量反映的客体运动方式与主观报告结果相分离的现象，并以两可刺激情景或实体性原则违背假设对该现象作了解释。本文以3个实验与其研究进行了商榷。结果表明，两可刺激情景与实体性违背均不能解释上述分离现象（实验1）；其实验范式中混入了距离因素（实验2与实验3）和方位朝向因素（实验1）。基于本研究的结果，笔者认为Mitroff等人的OSPBs效应是由距离效应和方位倾斜效应所致，即可能主要反映了基于空间的选择性注意的影响，而不能以客体表征连续性加以解释。

It is widely accepted that Object Files（OFs） are mid- level representations which mediate our conscious perception of persisting objects. However, Mitroff et al. （2005）have suggested the divergence between the conscious percepts of ＂which went where＂ in dynam- ic ambiguous displays and the analogous correspon- dence computed by the Object File system; though the movements of the objects were explicitly ＂streamed＂, the OFs manifested otherwise （i. e. ＂bounced＂）. The result challenged the OFs as mid- level representations in visual perception. However, their findings still remain questionable. To explore this issue, three experiments were conducted in the present study. It was revealed that ambiguous dis- plays and violation of solidity constraints which Mitroff et al. proposed were not proper explanations for the divergence （Exp. 1）. Further investigation showed that Mitroff et al.＇ s results may be confounded by distance（ Exp. 2 and Exp. 3） that the target stimulus was closer to ipsi-lateral previewed stimulus than to the eontra-lateral one, and orienta- tion（ Exp. 1）. Based on the findings of the present study, the author argued that OSPBs effect cannot be fully accounted for by the object representation continuity; rather it is vulnerable to the space-based selective attention. Thus, researchers need to be cautious while distinguishing ＂pure OSPBs＂ from ＂illu- sory OSPBs＂.
