The rise of the multiracial population has been met with a growing body of research examining multiracial face perception. A common method for creating multiracial face stimuli in past research has been mathematically averaging two monoracial "parent" faces of different races to create computer-generated multiracial morphs, but conclusions from research using morphs will only be accurate to the extent that morphs yield perceptual decisions similar to those that would be made with real multiracial faces. The current studies compared race classifications of real and morphed multiracial face stimuli. We found that oval-masked morphed faces were classified as multiracial significantly more often than oval-masked real multiracial faces (Studies 1 and 2), but at comparable levels to unmasked real multiracial faces (Study 2). Study 3 examined factors that could explain differences in how morphs and real multiracial faces are categorized and pointed to the potential role that unusualness/distinctiveness might play.
多民族人口的增加引发了大量研究，这些研究旨在探究多民族的面部感知。在过去的研究中，一种常见的创建多民族面部刺激的方法是通过数学平均两种不同种族的单种族“父母”面孔，以创建计算机生成的多民族变形，但是使用变形进行研究的结论只有在变形产生的感知决策与使用真实多民族面孔做出的决策相似的情况下才准确。当前的研究比较了真实和变形的多民族面部刺激的种族分类。我们发现，椭圆形掩蔽的变形面孔被归类为多民族的频率明显高于椭圆形掩蔽的真实多民族面孔（研究 1 和 2），但与未掩蔽的真实多民族面孔的水平相当（研究 2）。研究 3 探讨了可以解释变形和真实多民族面孔分类差异的因素，并指出不寻常/独特性可能发挥的作用。
