The research method used is "high-amplitude sucking," where changes in an infant's sucking behavior (such as increased sucking rate) are used to infer the infant's preferences or perceptual abilities. In this scenario, the infant's sucking behavior controls the auditory stimulus, which is a characteristic of the high-amplitude sucking method.
