Studies of the Sucking Reflex

A second area in which habituation and sensitization responses have been the subject of extensive investigation is the sucking reflex exhibited by human infants. When the cheeks or lips of a young child are touched with a nipple or finger, the infant will automatically begin sucking. In a study designed to explore how various stimuli affect this reflex, it was shown that babies respond much more vigorously to a bottle nipple than to the end of a piece of rubber tubing. In addition, repeated presentation of a bottle nipple causes an increase in sucking response, whereas repeated stimulation with rubber tubing causes a decrease in sucking. The sensitized or elevated response to a rubber nipple is a result of activation of the state system, which increases the baby's awareness and readiness to respond. Sensitization, however, does not occur when the baby is stimulated with rubber tubing, and instead the child habituates to this stimulus.
