The study of responses to sensory stimulation in the newborn by controlled techniques
facilitates insight into regulatory functions. These are dependent upon behavioral
state and may vary with the sensory modality tested. 50 newborns were investigated.
During regular sleep habituation to optic and exteroceptive stimuli occurred, measurable
as progressive diminution of the blink reflex. Simultaneously discriminative abilities
and their limitations became evident.
