Human beings possess a remarkable ability to recognise familiar faces quickly and without apparent effort. In spite of this facility, the mechanisms of visual recognition remain tantalisingly obscure. An experiment is reported in which image processing equipment was used to displace slightly the features of a set of original facial images to form groups of modified images. Observers were then required to indicate whether they were being shown the "original" or a "modified" face, when shown one face at a time on a TV monitor screen. Memory reinforcement was provided by displaying the original face at another screen position, between presentations. The data show, inter alia, the very high significance of the vertical positioning of the mouth, followed by eyes, and then the nose, as well as high sensitivity to close-set eyes, coupled with marked insensitivity to wide-set eyes. Implications of the results for the use of recognition aids such as Identikit and Photofit are briefly discussed.
人类拥有一种非凡的能力，能够迅速且毫不费力地识别熟悉的面孔。尽管具备这种能力，但视觉识别机制仍然极其模糊。本文报告了一项实验，其中使用图像处理设备对一组原始面部图像的特征进行轻微移位，以形成修改后的图像组。然后，当在电视监视器屏幕上一次显示一张面孔时，要求观察者指出他们看到的是“原始”面孔还是“修改后”的面孔。在每次展示之间，通过在另一个屏幕位置显示原始面孔来提供记忆强化。数据尤其表明，嘴巴的垂直位置、其次是眼睛、然后是鼻子具有非常高的重要性，同时对两眼间距近高度敏感，而对两眼间距宽则明显不敏感。本文简要讨论了这些结果对诸如组合照片拼图和面部合成照片等识别辅助工具使用的影响。
