Study of the Emergence of Sensory Self-awareness in Premature Newborns Using the Rooting Reflex

The procedure consists of brief perioral tactile stimulation. The procedure is filmed in order to record and evaluate the response of the newborn to the stimulation. During the same intervention, each newborn will receive external stimulation (the experimenter repeatedly and regularly touches the corner of the infant's mouth slowly with the tip of his index finger) followed by facilitated self-stimulation (the experimenter will place the newborn's elbow close to his body, allowing him to touch his face alone with his hand). There will also be an initial phase and a final 30-second phase in which the newborn is observed without any stimulation.
