研究了两个著名面孔（特里·沃根和西里尔·史密斯）内特征位移的影响。图像处理设备用于产生刺激，其中原始面部图像的特征被置换以形成许多修改的图像。这项技术首先由 Haig 在一项识别研究中报道，该研究调查了陌生面孔中特征位移的影响。在本实验中，进行了一项感知判断任务，其中向受试者展示了许多经过修改的面孔，并要求受试者判断这些面孔与原始图像有多么不同。对受试者比较判断的多维尺度分析揭示了涉及眼睛和嘴巴位移的二维解决方案。观察到这些特征（特别是眼睛）内的上/下和向内/向外位移之间存在明显的区别。对于这两张知名面孔，我们发现了类似的结果模式。这一结果表明，受试者对不同类型的特征位移（水平或垂直）产生的面部构造变化做出反应，而不是对特征本身的移动做出反应。最后，结果还表明，内部特征（嘴、眼睛、鼻子）的位移比外部面部特征（例如发际线）的位移更明显。
The effect of feature displacement within two well-known faces (Terry Wogan and Cyril Smith) was examined. Image processing equipment was used to produce stimuli in which the features of an original facial image were displaced to form a number of modified images. This technique was first reported by Haig, in a recognition study in which the effect of feature displacement within unfamiliar faces was investigated. In the present experiment a perceptual judgement task was carried out in which subjects were presented with a number of modified faces and asked to judge how dissimilar these were with respect to an original image. A multidimensional scaling analysis of the comparative judgements of the subjects revealed a two-dimensional solution involving displacement of the eyes and mouth. A clear division between up/down and inward/outward displacement within these features (particularly the eyes) was observed. A similar pattern of results was found for both well-known faces. This result indicates that subjects were responding to changes in the facial configuration produced by the different types of feature displacement (horizontal or vertical), as opposed to movement of the features per se. Finally, the results also indicate that the displacement of inner features (mouth, eyes, nose) was more noticeable than displacement of the outer facial features (eg hairline).
