当物体的碎片线画相对于随机定向线条的背景移动时，先前隐藏的物体可以与背景分离并因此进入意识。在这种运动形状范式中，物体的感知在运动停止后短暂持续，这表明意识中绑定感知的维持。这项研究调查了对识别至关重要的物体特征的操纵如何影响绑定过程和物体在意识中的维持。总体而言，我们发现识别时间较长的物体（即缺少顶点的物体）在意识中保持的时间仍然较长。我们认为，这种效应是通过额外的精细处理来调节的，这些处理需要结合这些难以识别的形式，从而产生更强大和更稳健的表示。这些表征更容易被维持在意识中，这表明精细机制对于意识表征的重要作用。 (C) 2007 Elsevier Inc. 保留所有权利。
When a fragmented line-drawing of an object moves relative to a background of randomly oriented lines, the previously hidden object can be segregated from the background and consequently enters awareness. In this shape-from-motion paradigm, the percept of the object briefly persists after the motion stops, demonstrating the maintenance of a bound percept in awareness. This study investigated how the manipulation of object features that are crucial to recognition influences both the binding process and the maintenance of objects in awareness. Overall, we found that objects that took longer to recognize (i.e., objects missing their vertices) were nonetheless maintained in awareness for longer. We argue that this effect is mediated by additional elaborative processing that is required to bind these less recognizable forms, which generates stronger and more robust representations. These representations are then more easily maintained in awareness, suggesting an important role of elaborative mechanisms for conscious representations. (C) 2007 Elsevier Inc. All rights reserved.
