Abstract: | A number of recent studies have indicated that newborns can learn to recognize mother's face within a few hours of birth. Two of the present authors suggested that a simple auto-associative net might explain that rapid learning. This paper reports three experiments in which the newborn's ability to recognize a learned face over three transformations was tested. The transformations were: (1) a photonegative transformation, (2) a size change and (3) rotation in the third dimension of visual space. Existing auto-associative nets cannot maintain identification across these transformations. The newborns succeeded with all three. An alternative proposal based on the idea that there is a built-in specification of the true shape of a face in the frontal parallel plane is outlined. These data present a challenge not only to associationist theories but also to their main rival, differentiation theory. |
