本研究探讨是否基于对象的注意选择取决于观察者的对象的意识，使用的对象定义的知觉完成。作为基于对象的注意力的指标，我们研究了同一对象的优势，观察者对线索对象内的目标的反应比非线索对象内的反应更快。同一物体优势在观察者没有注意到物体的条件下（无意视盲）没有被发现。另一方面，在观察者意识到物体的条件下，观察到了相同物体的优势。这些结果表明，对象表征的强度可以通过观察者的对象意识，从而影响基于对象的效果的发生。我们建议，注意力/注意力不集中（或意识/无意识）是分级的，观察者对对象的意识可能有助于提高其他噪声/低信号表示，以获得基于对象的效果。
This study examined whether object-based attentional selection depends on the observer's awareness of objects, using objects defined by perceptual completion. As an indicator of object-based attention, we studied the same-object advantage, where observers respond faster to a target within a cued object than within a noncued object. The same-object advantage was not found in the condition where observers were unaware of the objects (inattentional blindness). On the other hand, the same-object advantage was observed in the condition where observers were aware of the objects. These results suggest that the intensity of object representations can be influenced by observers’ awareness of objects, which affects the occurrence of object-based effects. We propose that attention/inattention (or awareness/unawareness) is graded and observers’ awareness of the objects might serve to boost an otherwise noisy/low signal representation for obtaining object-based effects.
