本研究将对象审查范式（Kahneman、Treisman 和 Gibbs，1990）与方格阴影错觉相结合，以便对比对象亮度与亮度对特定对象预览效果的影响。为此，我们在四个实验中操纵了对象的亮度和信息丰富的背景场景给出的照明量。与之前的研究一致，当对象呈现在统一颜色的背景上并且在对象之间切换亮度时，没有特定于对象的预览优势。相比之下，当对象呈现在为亮度切换提供解释的方格阴影幻觉背景上时，观察到可靠的特定于对象的预览优势。这表明，通过对象审查范式测量的对象对应性可能会受到场景引起的、感知到的对象表面亮度的影响。我们重复了这一发现，此外还表明，如果对象被视为背景场景的一部分，则场景上下文只会影响特定于对象的预览效果。
The present study combines the object-reviewing paradigm (Kahneman, Treisman, & Gibbs, 1990) with the checkershadow illusion in order to contrast the effects of objects’ luminance versus lightness on the object-specific preview benefit. To this end, we manipulated objects’ luminance and the amount of illumination given by an informative background scene in four experiments. In line with previous studies, there was no object-specific preview benefit when objects were presented on a uniformly colored background and luminance switched between objects. In contrast, when objects were presented on the checkershadow illusion background which provided an explanation for the luminance switch, a reliable object-specific preview benefit was observed. This suggests that object correspondence as measured by the object-reviewing paradigm can be influenced by scene-induced, perceived lightness of objects’ surfaces. We replicated this finding and moreover showed that the scene context only influences the object-specific preview benefit if the objects are perceived as part of the background scene.
