  As mentioned above, Piaget (1954) proposed that sensorimotor coordinations gradually lead to construction of the object concept. Establishing these coordinations between different modes of perceptual experience—vision and touch, for example—would take time, and Piaget proposes that it is not until the child is 18–24 months that these coordinations have been constructed. Meltzoff &amp; Moore 1977 provide counter-evidence to this claim. This study shows that newborn infants can imitate the facial movements of an experimenter, clearly revealing the coordination of their own movements (along with the attendant feelings of their muscles) and their visual perception of the experimenter’s facial movements. The following video links (Ferrari et al. 2006,  videos S1 and S2) provide some evidence that newborn rhesus macaques have this ability as well. Insofar as these coordinations of different modes of perceptual experience are present at birth in humans and in monkeys, they simply could not be the products of learning.
