Theories of object recognition have emphasized the information conveyed by shape information, whereas theories of face recognition have emphasized properties of superficial features. In the experiments reported here we used novel technology to investigate the relative contributions of shape and superficial colour information to simple categorization decisions about the sex and 'race' of faces. The results show that both shape and colour provide useful information for these decisions; shape information was particularly useful for race decisions while colour dominated sex decisions. When both sources of information were combined, the dominant source depended on viewpoint, with angled views emphasizing the contribution of shape and the full-face view colour. The results are discussed within the context of theories of face recognition and their implications for telecommunication applications are considered.
物体识别理论强调形状信息所传达的内容，而人脸识别理论则强调表面特征的属性。在本文所报告的实验中，我们使用新技术来研究形状和表面颜色信息对关于面部性别和“种族”的简单分类决策的相对贡献。结果表明，形状和颜色都为这些决策提供了有用信息；形状信息在种族决策中特别有用，而颜色在性别决策中占主导地位。当两种信息源结合时，主导信息源取决于视角，倾斜视角强调形状的贡献，正面视角则强调颜色的贡献。我们将在人脸识别理论的背景下讨论这些结果，并考虑它们对电信应用的影响。
