摘要：

We investigated the organization of arousal and attention processes in 138 neurologically at-risk neonates by studying visual preferences when the infants were in 3 arousal conditions: less aroused (after feeding while swaddled), more aroused-internal (before feeding while unswaddled), and more aroused-external (after feeding while swaddled with 8-Hz visual stimulation before each trial). The stimuli were unpatterned light panels illuminated at temporal frequencies of 1, 2, 4, and 8 Hz. Four brain insult groups were defined by cranial ultrasonography and brainstem auditory evoked response tests. There were no differences in looking preferences in the 2 more aroused conditions. A previously reported interaction between arousal level and stimulus frequency was replicated, with infants preferring faster frequencies when arousal was decreased. Brain insult reduced this interaction by shifting preference functions when less aroused toward less stimulation.
