在先前的研究中，我们发现一些物体识别过程会影响图形-背景组织。我们已经提出，这些对象识别过程中的边缘（或轮廓）检测到的视觉处理，而不是在区域。与这个提议相一致的是，物体识别对图形-背景组织的影响以前在描绘不同亮度区域的图片和立体图中都观察到过，但在随机点立体图中没有观察到，在随机点立体图中，边缘在处理后期出现（Peterson &吉布森，1993）。在本实验中，我们研究了其他两种类型的轮廓轮廓和主观轮廓，使物体识别的图形背景组织的影响。对于这两种类型的轮廓，我们观察到一种模式的效果类似于最初获得的亮度边缘。这些实验的结果是有价值的，以区分不同的观点的机制介导的对象识别的影响，图形-背景组织。此外，在实验1和实验2中，固定区域被认为是图比nonfixed区域，这表明固定位置必须包括在变量之间的图形-背景组织。
In previous research, replicated here, we found that some object recognition processes influence figure-ground organization. We have proposed that these object recognition processes operate on edges (or contours) detected early in visual processing, rather than on regions. Consistent with this proposal, influences from object recognition on figure-ground organization were previously observed in both pictures and stereograms depicting regions of different luminance, but not in random-dot stereograms, where edges arise late in processing (Peterson & Gibson, 1993). In the present experiments, we examined whether or not two other types of contours-outlines and subjective contours-enable object recognition influences on figure-ground organization. For both types of contours we observed a pattern of effects similar to that originally obtained with luminance edges. The results of these experiments are valuable for distinguishing between alternative views of the mechanisms mediating object recognition influences on figure-ground organization. In addition, in both Experiments 1 and 2, fixated regions were seen as figure longer than nonfixated regions, suggesting that fixation location must be included among the variables relevant to figure-ground organization.
