Infants in newborn intensive and convalescent care units are exposed to large amounts of sensory stimulation of various sorts. Although infants in these units do not lack visual, auditory, and tactile stimulation, they receive relatively infrequent coordinated sensory experiences. Furthermore, there is no diurnal rhythmicity in physical and social stimulation across days.
新生儿重症监护病房和康复护理病房的婴儿会接触到大量各种各样的感官刺激。虽然这些病房的婴儿并不缺乏视觉、听觉和触觉刺激，但他们获得的协调感官体验相对较少。此外，在数天内，身体和社交刺激不存在昼夜节律。
