目前的研究旨在调查3个月大婴儿对自己和其他物种的偏好。这些婴儿的眼球运动被记录在视觉偏好范式中，以评估他们在与其他物种的面孔相比时是否表现出对自己物种的面孔的偏好。研究人员使用了人类和猴子的脸，这些脸等同于所有低级知觉特征。我们的结果表明，3个月大的婴儿更喜欢人脸，这表明在与特定类别的人脸进行3个月的视觉体验后，人脸感知系统变得特定于物种。眼球跟踪结果还显示，人们的注视更多地集中在人脸的眼睛区域，这支持了他们在保持视觉注意力方面的重要性的概念。
The current study aimed at investigating own- vs. other-species preferences in 3-month-old infants. The infants' eye movements were recorded during a visual preference paradigm to assess whether they show a preference for own-species faces when contrasted with other-species faces. Human and monkey faces, equated for all low-level perceptual characteristics, were used. Our results demonstrated that 3-month-old infants preferred the human face, suggesting that the face perception system becomes species-specific after 3 months of visual experience with a specific class of faces. The eye tracking results are also showing that fixations were more focused on the eye area of human faces, supporting the notion of their importance in holding visual attention.
