The sucking movements of infants were analysed by means of a physiological methods. It was particularly aimed at clarifying the properties which control the regulating system of the sucking movements. The nutritive sucking rhythms of human infants were found to be regulated by the food intake system, while the non-nutritive sucking rhythms were controlled by the respiratory and vocal system. By means of the respiratory and vocal system peculiar properties of development and growth are germinated in human infants which are unknown in other mammals.<BR>In consideration of the above it is believed that the period of non-nutritive sucking bridges the gap from the state of wakeful activity to the state of restfulness and sleep. When pre-verbal communication comes into existence which establishes the relationship between the subject and its surrounding world non-nutritive sucking movements are no longer observed.
