A standard facial-caricaturing algorithm was applied to a three-dimensional representation of human heads. This algorithm sometimes produced heads that appeared 'caricatured'. More commonly, however, exaggerating the distinctive three-dimensional information in a face seemed to produce an increase in the apparent age of the face--both at a local level, by exaggerating small facial creases into wrinkles, and at a more global level via changes that seemed to make the underlying structure of the skull more evident. Concomitantly, de-emphasis of the distinctive three-dimensional information in a face made it appear relatively younger than the veridical and caricatured faces. More formally, face-age judgments made by human observers were ordered according to the level of caricature, with anticaricatures judged younger than veridical faces, and veridical faces judged younger than caricatured faces. These results are discussed in terms of the importance of the nature of the features made more distinct by a caricaturing algorithm and the nature of human representation(s) of faces.
一种标准的面部 caricaturing 算法被应用于人类头部的三维表示。该算法有时会生成看起来像“漫画化”的头部。然而，更常见的情况是，夸大面部独特的三维信息似乎会使面部的表观年龄增加——在局部层面，通过将小的面部皱纹夸大成长皱纹，以及在更全局的层面，通过一些似乎使头骨的基础结构更明显的变化。与此同时，对面部独特三维信息的弱化使其看起来比真实和漫画化的面部相对更年轻。更正式地说，人类观察者做出的面部年龄判断根据漫画化程度进行排序，反漫画化的面部被判断为比真实面部年轻，真实面部被判断为比漫画化面部年轻。这些结果将根据漫画化算法使更明显的特征的性质以及人类对面部的表征性质进行讨论。
