5. The results of Kelly and colleagues’ research on specialized face processing in infancy showed that during the
first year
a. the ability to recognize own-race faces was retained, while the ability to individuate other-race faces was
reduced — demonstrating a pattern of perceptual narrowing.
b. the ability to recognize and individuate own-race and other-race faces was reduced — demonstrating a
pattern of perceptual narrowing.
c. the ability to recognize own-race faces was lost, while the ability to individuate other-race faces was
increased — demonstrating a pattern of perceptual constancy.
d. the ability to recognize and individuate own-race and other-race faces was lost — demonstrating a pattern of
perceptual constancy.
