Abstract

Face images depicting the same individual can differ substantially from one another. Ecological variation in pose, expression, lighting, and other sources of appearance variability complicates the recognition and matching of unfamiliar faces, but acquired familiarity leads to the ability to cope with these challenges. Among the many ways that face of the same individual can vary, some images are judged to be better likenesses of familiar individuals than others. Simply put, these images look more like the individual under consideration than others. But what does it mean for an image to be a better likeness than another? Does likeness entail typicality, or is it something distinct from this? We examined the relationship between the likeness of face images and the similarity of those images to average images of target individuals using a set of famous faces selected for reciprocal familiarity/unfamiliarity across US and UK participants. We found that though likeness judgments are correlated with similarity-to-prototype judgments made by both familiar and unfamiliar participants, this correlation was smaller than the correlation between similarity judgments made by different participant groups. This implies that while familiarity weakens the relationship between likeness and similarity-to-prototype judgments, it does not change similarity-to-prototype judgments to the same degree.

不正常:面部相似并不等同于与熟悉的面部原型相似。
描绘同一个人的面部图像彼此之间可能存在很大差异。姿势、表情、光线和其他外观变化来源的生态变化使对陌生面孔的识别和匹配变得复杂,但获得的熟悉性导致应对这些挑战的能力。同一个人的脸可以有很多不同的方式,其中一些照片被认为比其他照片更像熟悉的人。简单地说,这些图像看起来比其他图像更像被考虑的个体。但是,一个图像比另一个图像更像是什么意思呢?相似意味着典型性,还是与之截然不同?我们研究了面部图像的相似性和这些图像与目标个体平均图像的相似性之间的关系,使用了一组在美国和英国参与者中选择的著名面孔作为相互熟悉/不熟悉的对象。我们发现,尽管熟悉和不熟悉的参与者做出的相似性判断与原型相似性判断相关,但这种相关性小于不同参与者群体做出的相似性判断之间的相关性。这意味着,虽然熟悉程度削弱了相似性和相似性到原型判断之间的关系,但它并没有在相同程度上改变相似性到原型判断。
