The same-object benefit, that is faster and/or more accurate performance when two target properties to be identified appear on one object than when each of the properties appear on different objects, has been a robust and theoretically important finding in the study of attentional selection. Indeed, the same-object benefit has been interpreted to suggest that attention can be used to select objects and perceptual groups rather than unparsed regions of visual space. In the present studies we report and explore a different-object benefit, that is faster identification performance when two target properties appear on different objects than when they appear on a single object. The results from the three experiments suggest that the different-object benefit was the result of mental rotation and translation strategies that subjects performed on objects in an effort to determine whether two target properties matched or mismatched. These image manipulation strategies appear to be performed with similar but not with dissimilar target properties. The results are discussed in terms of their implications for the study of object-based attentional selection.
同客体优势，即在识别两个目标属性时，当这两个属性出现在一个客体上比出现在不同客体上时，表现得更快和/或更准确，这是注意力选择研究中一个稳健且具有理论重要性的发现。事实上，同客体优势被解释为表明注意力可用于选择客体和知觉群组，而非视觉空间中未解析的区域。在本研究中，我们报告并探究了异客体优势，即当两个目标属性出现在不同客体上比出现在单个客体上时，识别表现更快。三个实验的结果表明，异客体优势是被试对客体执行心理旋转和平移策略的结果，目的是确定两个目标属性是匹配还是不匹配。这些图像操纵策略似乎是针对相似而非不相似的目标属性执行的。我们从这些结果对基于客体的注意力选择研究的意义方面进行了讨论。
