Stimulus and motoric influences on visual habituation to facial stimuli at 3 months
Research has shown that the short-term reliability of 3-month-olds' visual behavior is lower than that of older infants. The present study examined whether reliability might be improved under more constrained stimulus conditions, and explored the contribution of infants' motor development to visual habituation and subsequent discrimination measures. Twenty-two 3-month-olds were seen for 2 visual habituation-discrimination sessions 1 week apart in which stimulus features were more constrained than in a previously conducted comparable study. The test-retest reliability across these 2 testings was better than that reported previously, suggesting that stimulus factors may be a critical factor in the reliability of young infants' visual behavior. Additionally, shorter fixations and more shallow habituation decrements were also strongly and consistently associated with advanced motor development. © 1987.
