我们报告的两项实验表明，改变面部特征的配置会改变对面部开窗的椭圆形光圈的感知：当正面面部照片的眼睛和嘴巴垂直向面部边界移动时，椭圆形显得越来越拉长、更高和更窄；当眼睛和嘴巴向鼻子移动时，椭圆形会显得越来越圆、越来越短、越来越宽。当面部在椭圆形内直立时，并且主要面部特征（眼睛、鼻子和嘴巴）出现在正确的相对位置时，这种形状错觉会最大化。这些结果表明，面部配置的处理可以影响与面部共享视觉空间的几何形状的感知。讨论了这种错觉是特定于面部的还是更一般的几何错觉的特殊情况。
We report two experiments indicating that varying the configuration of face features changes perception of an oval aperture windowing the face: as the eyes and mouth of a frontal-view face photograph are moved vertically toward face boundaries, the oval appears increasingly elongated, taller, and narrower; when eyes and mouth are moved toward the nose, the oval appears increasingly rounder, shorter, and wider. This shape illusion is maximised when faces appear upright within the oval, and major face features (eyes, nose, and mouth) appear in their correct relative locations. These results establish that processing of a face configuration can affect perception of a geometric shape that shares visual space with a face. Whether the illusion is face-specific or a special case of a more general geometric illusion is discussed.
