ABSTRACT: 56 4-mo old long- and short-looking infants were habituated
to a visual form from which 50% of the contour
was removed. Ss were tested for recognition of the visual form
with paired comparison trials in which 2 other 50%-degraded
visual forms were simultaneously presented. One of the 2 degraded
forms presented was a novel form, and the other was
comprised of the "complementary contour" (i.e., the contour not
previously shown) of the degraded habituation stimulus,
thereby testing the Ss' recognition of a form across stimuli
that shared no common contour. Only Ss with shorter attentional
fixation durations recognized forms when tested this way. Results
suggest that some infants are capable of generalizing from
one complementary image to another; the observation of this ability
in only short-looking Ss being consistent with previous
suggestions of differences in visual encoding as a function of
individual differences in fixation duration. ((c) 1997
