If, however, a constancy is
based on an inference process,
as is probably the case in size
perception, experience may
play a role in its genesis. To
determine whether or not the
constancy of a perception is
innate, experiments must be
constructed that rule out
experience as a factor. One way
of doing so is to test animals or
infants at birth or shortly
thereafter; a more drastic way
is to test more mature animals
that have been prevented from
learning about the visual
world, usually by eliminating
their vision or pattern vision at
birth. Both methods have
inherent difficulties: One
might think that infants and
many animals are not mature
enough to test at birth, since
they are not capable of
locomotion or of learning to
discriminate between objects of
differing sizes or lightnesses,
while early deprivation of
vision may cause severe
deterioration of the visual
nervous system and prevent
normal maturation.
