Premature infant behavior: an ethological study in a special care nursery.

Abstract

The Social and Sensory Environment Studies of very low birthweight infants have quantified the amount and quality of social interaction with staff and parents and described the sound environment in an incubator. The present study concerns preterm infant behavior and reactions to these stimuli with particular reference to approach and withdrawal and vocalization. Among the findings are that while intermittent vocalization increases, infant cry decreases over the first three weeks in the incubator. Approach activities take place with some consistency whereas withdrawal differs from child to child. The ethnographic focus on interactive components of the intensive care experience documents the process of intersubjective development for the purpose of locating and isolating points of vulnerability in language and cognitive skills of infants born at very low birthweight.
