了解面部识别的发展起源一直是各种方法的许多研究的目标。经验预期机制(早期部分),例如知觉缩小,以及终生经验(晚期部分)对面部处理的贡献仍然难以捉摸。通过调查不同年龄的圈养黑猩猩(这是一种罕见的案例,该物种一生都以不同的经验水平接触非同种面孔),我们可以理清面孔识别的发育组成部分。我们发现,在年轻黑猩猩中,区分黑猩猩优于人类面孔的优势,反映了早期成分的主要贡献,该早期成分推动感知系统朝着同种形态发展;而在老年黑猩猩中,人类优于黑猩猩面孔的优势,反映了沿着所暴露的面部的关键维度塑造感知系统的主要晚期成分。我们使用计算模型模拟早期和晚期成分的贡献,并以数学方式描述底层功能。
Understanding the developmental origins of face recognition has been the goal of many studies of various approaches. Contributions of experience-expectant mechanisms (early component), like perceptual narrowing, and lifetime experience (late component) to face processing remain elusive. By investigating captive chimpanzees of varying age, a rare case of a species with lifelong exposure to non-conspecific faces at distinctive levels of experience, we can disentangle developmental components in face recognition. We found an advantage in discriminating chimpanzee above human faces in young chimpanzees, reflecting a predominant contribution of an early component that drives the perceptual system towards the conspecific morphology, and an advantage for human above chimpanzee faces in old chimpanzees, reflecting a predominant late component that shapes the perceptual system along the critical dimensions of the face exposed to. We simulate the contribution of early and late components using computational modeling and mathematically describe the underlying functions.
