This research examined four-month-old infants' use of featural information
(shape or color and pattern) to segregate a display into two adjacent piece
s. The infants were shown displays consisting of two objects that were the
same or different in shape and that were decorated with either similar or d
ifferent surface markings such that featural information could suggest that
the two portions were either connected or not. Three displays were created
that allowed the comparison of infants' use of shape information and color
and pattern information. The results suggest that, at four months of age,
infants are more likely to use shape differences than color and pattern dif
ferences to find object boundaries. The results are discussed in the contex
t of infants' learning about the utility of different sources of informatio
n for predicting object boundary locations.
