Two major hypotheses were investigated: 1) that preterm infants have an elevated sensory threshold leaving them relatively unavailable to stimulation and 2) that once the preterm is stimulated sufficiently to respond, he/she is largely unable to habituate to repeated stimulus presentations. Additionally, the reliability of responsiveness and habituation over a 24-hour period was assessed.Newborn infantsPremature infantsthesis32258589
