Converging developmental studies stress the importance for infant development of early behaviors, starting from the fetal stage. Nevertheless, many aspects of the underlying mechanisms required to perform these behaviors are still unclear. In this paper, we propose that these behaviors are the result of a process of self-organization guided by a principle of sensorimotor integration based on sensory restrictions. To examine the early developmental scenario, two types of simulations based on musculoskeletal body models are conducted. We show that sensory information flow triggers two important developmental transitions. First, in the fetus model, hand-face contact behaviors are induced by the nonuniform distribution of tactile sensors. Second, in the infant model, hand regard behaviors facilitating self-observation of the hand are induced by the nonuniform visual resolution. Our results suggest that sensory restrictions could drive the development of behaviors in an embodied and self-organized manner.
