This film provides descriptive documentation of variations in oral behavior in infants under 24 weeks of age. Infants are shown at different stages, moving their arms and legs, placing fingers, toes, and other objects in their mouths, licking items, grabbing a ring suspended above them, and biting a sterling silver cup. Behavior prior to feeding and after feeding is shown, with variations in infant response. The film shows that the degree of differentiation in mouth movements depends on neuromuscular maturation, different kinds of oral behavior, and individual modifications, which are a reflection of "feeling states." The film is intended for professional persons interested in developmental psychology and also as a teaching aid for students engaged in behavior observations.
The National Library of Medicine believes this item to be in the public domain. (More information)
