为了研究轮廓曲率极性，我们比较了严格凸区域（圆形图形）与严格凹区域（圆孔）。我们测试了视觉搜索凹面和凸面之间的不对称性。我们发现，提供一个预览的背景有利于搜索凹（洞）比它没有搜索凸（数字），凸的数字，更近的目标更快地作出反应。然而，重要的是，我们没有找到任何支持凹目标本质上更突出的假设。我们的结论是，以前的研究结果在文献中，这已被用来表示优先处理的凹部，由于其增加的显着性，更有可能的结果，早期计算的部分结构的凹部的基础上。
To study contour curvature polarity, we compared strictly convex regions (circular figures) with strictly concave regions (circular holes). We tested for an asymmetry between visual searches for concavities and those for convexities. We found that providing a preview of the background benefited search for concavities (holes) more than it did search for convexities (figures) and that for convex figures, nearer targets were responded to more quickly. Importantly, however, we failed to find any support for the hypothesis that concave targets are inherently more salient. We conclude that previous findings in the literature, which have been taken to indicate preferential processing of concavities, due to their increased salience, are more likely the result of an early computation of part structure based on concavities.
