暴露和先天神经网络对同种和非特异性面孔加工的各自影响尚不清楚。虽然暴露在物体和面部识别的发展中的重要性一般是有据可查的，但明确比较不同物种面部识别的研究显示了物种特异性效应。例如，每天暴露在人类面孔下的实验室猴子比人类更善于区分猴子，这表明暴露的作用可能不是影响跨物种识别的唯一因素。在本研究中，作者研究了来自两个灵长类中心的黑猩猩（Pan troglodytes）的同种和非同种面孔识别，这两个中心提供了不同的黑猩猩和人类面孔暴露。研究人员发现，在研究中心的黑猩猩中，那些对人类面孔的接触比对黑猩猩面孔的接触更多的黑猩猩，在辨别人类面孔方面比在辨别黑猩猩面孔方面做得更好。另一个研究中心的黑猩猩没有表现出同样的效果。一个计算模拟，以评估人类图片和黑猩猩图片之间的平均相似性。这两个类别具有可比性。黑猩猩的得分与相似系数呈显著相关。总体而言，结果表明，曝光是一个关键的决定因素，同种和非同种面孔识别。
The respective influences of exposure and inborn neural networks on conspecific and nonconspecific face processing remain unclear. Although the importance of exposure in the development of object and face recognition in general is well documented, studies explicitly comparing face recognition across species showed a species-specific effect. For instance, laboratory monkeys exposed daily to human faces were better at discriminating monkeys than humans, suggesting that the role of exposure may not be the only factor affecting cross-species recognition. In the present study, the authors investigated conspecific and nonconspecific face recognition in chimpanzees (Pan troglodytes) from 2 primate centers that provided different exposure to chimpanzee and human faces. The authors showed that the chimpanzees from the center providing more exposure to human faces than to chimpanzee faces were better at discriminating human faces than they were at discriminating chimpanzee faces. The chimpanzees from the other center did not show the same effect. A computational simulation was developed to evaluate the average similarities among human pictures and among chimpanzee pictures. Both categories were comparable. Chimpanzees' scores were significantly correlated with the similarity coefficients. Overall, the results show that exposure is a critical determinant in conspecific and nonconspecific face recognition.
