Some stimuli may not be perceived at all, for example a nipple is presented but no suck occurs, as if the volume button for the mouth has been turned to "low." Other stimuli may elicit too great a response for the amount of stimuli presented, for example a light touch to the lip may result in excessive gagging, as if the volume button has been set on "high." These situations are known as "oral defensiveness."
