采用同异辨别任务，研究了4只虎皮鹦鹉（Melopsittacusundulatus）的面孔知觉。反应时间被视为成对面孔之间相似性的衡量标准，并通过多维缩放进行分析，以揭示面孔之间的相似性模式。测试自然面孔的感知，以确定哪些特征在感知上是突出的。颜色、斑纹图案、虹膜暗度和瞳孔大小与观察到的面部相似性模式相对应。虎皮鹦鹉的脸之间的差异更显着比斑胸草雀的脸之间的差异，和虎皮鹦鹉的脸是感知不同的其他鸟类物种的脸。这些实验的结果为理解这些信号在协调社会行为中的作用方式提供了基础。
Perception of faces by 4 budgerigars (Melopsittacus undulatus), a species of small parrot, was studied with a same-different discrimination task. Reaction times were taken as a measure of the similarity between pairs of faces and analyzed with multidimensional scaling to reveal patterns of similarity among the faces. The perception of natural faces was tested to determine which characteristics were perceptually salient. Color, patterns of markings, darkness of the iris, and size of the pupil corresponded to the observed patterns of similarity among the faces. Differences among budgerigar faces were more salient than differences among zebra finch faces, and budgerigar faces were perceptually distinct from the faces of other avian species. The results from these experiments provide a basis for understanding the ways in which these signals function in the coordination of social behaviors.
