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 clongated, 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.
我们报告了两项实验，结果表明改变面部特征的配置会改变对面部椭圆形孔径的感知：随着正视图面部照片中的眼睛和嘴巴垂直移向面部边界，椭圆形看起来越来越细长、更高且更窄；当眼睛和嘴巴移向鼻子时，椭圆形看起来越来越圆、更短且更宽。当面部在椭圆形内呈现直立且主要面部特征（眼睛、鼻子和嘴巴）处于其正确相对位置时，这种形状错觉会最大化。这些结果表明，对面部配置的处理会影响与面部共享视觉空间的几何形状的感知。文中还讨论了这种错觉是面部特有的，还是更一般几何错觉的特殊情况。
