| Abstract | Despite the computational difficulty, adults easily recognize faces with incredibly high sensitivity and specificity across novel changes in viewing conditions. Mature face representations are invariant to identity-preserving changes (e.g., changes in expression or viewing angle) while intolerant to identity-transforming changes (e.g., changes in texture, age, and gender). Yet, due to constraints in testing newborn subjects, the origins of these characteristics remain unknown. Are highly sensitive, specific, and generative face representations the product of extensive visual experience, or do genes build neural machinery that generates sensitive, specific, and generative face representations from the onset of experience with faces? To probe the nature of the first face representation created in the newborn mind, we reared newborn chickens for one week in a virtual reality chamber that contained no objects except a single virtual human face (the “Virtual Parent”). Immediately after, the chickens were tested for one week on their ability to discriminate between the Virtual Parent and a set of distractor faces. Distractors were identical to the Virtual Parent, with the exception of a single dimension (e.g., changes in texture, structure, inversion, and expressions). Subjects were able to distinguish the Virtual Parent from distractors that differed in texture, age, gender, and inversion, but not distractors that differed in feature configuration or facial expression. Further, subjects were able to recognize the Virtual Parent across novel changes in head orientation (i.e., view direction), indicating that subjects built invariant face representations. These results show that the first face representation built by the newborn visual system can be sensitive, specific, and generative. |
