Objective: To
investigate visual habituation behavior of normal infants，to know
whether the function of infants' brain could be understood and anticipated
by means of behavior of habituation.
Methods: 538 normal
infants aged 0-3 years were exposed to a redundant visual stimulus repeated
6 times and novel one at 10-second intervals. Electronic control and
simultaneous camcorder system was applied to record infants' fixation time
to each stimulus. Response decrement and response recovery was calculated.
Results: The infants'
fixation time decreased gradually over 6 repeated trials
and recovered when a novel stimulus was given. Younger infants looked at the
stimuli longer than the older infants. The rate of response decrement as
well as response recovery increased with age.
Conclusion: As more
mature infants habituate more efficiently, it is anticipated that
habituation behavior can be used as an indicator to differentiate infants'
brain function.
