Facial information is processed by our brain in such a way that we immediately make judgments about, for example, attractiveness or masculinity or interpret personality traits or moods of other people. The appearance of each facial feature has an effect on our perception of facial traits. This research addresses the problem of measuring the size of these effects for five facial features (eyes, eyebrows, nose, mouth, and jaw). Our proposal is a mixed feature-based and image-based approach that allows judgments to be made on complete real faces in the categorization tasks, more than on synthetic, noisy, or partial faces that can influence the assessment. Each facial feature of the faces is automatically classified considering their global appearance using principal component analysis. Using this procedure, we establish a reduced set of relevant specific attributes (each one describing a complete facial feature) to characterize faces. In this way, a more direct link can be established between perceived facial traits and what people intuitively consider an eye, an eyebrow, a nose, a mouth, or a jaw. A set of 92 male faces were classified using this procedure, and the results were related to their scores in 15 perceived facial traits. We show that the relevant features greatly depend on what we are trying to judge. Globally, the eyes have the greatest effect. However, other facial features are more relevant for some judgments like the mouth for happiness and femininity or the nose for dominance.

每个面部特征对我们感知和解释人脸的方式的影响

面部信息由我们的大脑处理，因此我们可以立即做出判断，例如是否具有吸引力或阳刚之气，或解释他人的性格特征或情绪。每个面部特征的出现都会影响我们对面部特征的感知。这项研究解决了测量五个面部特征（眼睛，眉毛，鼻子，嘴巴和下巴）的效果大小的问题。我们的建议是基于特征和基于图像的混合方法，它允许对分类任务中完整的真实面孔做出判断，而不是对影响评估的合成，嘈杂或局部面孔做出判断。使用主成分分析，会考虑到它们的全局外观来自动分类脸部的每个脸部特征。使用此过程，我们建立了一组简化的相关特定属性（每个属性描述一个完整的面部特征）来表征面部。通过这种方式，可以在感知到的面部特征与人们直觉认为的眼睛，眉毛，鼻子，嘴巴或下巴之间建立更直接的联系。使用此程序对一组92张男性面孔进行分类，结果与他们在15个感知的面部特征中的得分相关。我们表明，相关功能很大程度上取决于我们要判断的内容。在全球范围内，眼睛的影响最大。但是，其他面部特征与某些判断更相关，例如，嘴巴代表幸福和女人味，鼻子则代表优势。可以在感知到的面部特征与人们直觉认为的眼睛，眉毛，鼻子，嘴巴或下巴之间建立更直接的联系。使用此程序对一组92张男性面孔进行分类，结果与他们在15个感知的面部特征中的得分相关。我们表明，相关功能很大程度上取决于我们要判断的内容。在全球范围内，眼睛的影响最大。但是，其他面部特征与某些判断更为相关，例如，嘴巴代表幸福和女人味，鼻子则代表优势。可以在感知到的面部特征与人们直觉认为的眼睛，眉毛，鼻子，嘴巴或下巴之间建立更直接的联系。使用此程序对一组92张男性面孔进行分类，结果与他们在15个感知的面部特征中的得分相关。我们表明，相关功能很大程度上取决于我们要判断的内容。在全球范围内，眼睛的影响最大。但是，其他面部特征与某些判断更相关，例如，嘴巴代表幸福和女人味，鼻子则代表优势。我们表明，相关功能很大程度上取决于我们要判断的内容。在全球范围内，眼睛的影响最大。但是，其他面部特征与某些判断更相关，例如，嘴巴代表幸福和女人味，鼻子则代表优势。我们表明，相关功能很大程度上取决于我们要判断的内容。在全球范围内，眼睛的影响最大。但是，其他面部特征与某些判断更相关，例如，嘴巴代表幸福和女人味，鼻子则代表优势。
