In daily life, however, we are
usually required to discriminate
among similar members of a
class. The infant must learn its
parentsΓÇÖ faces, the child must
learn to read, the zookeeper
must learn to differentiate the
monkeys, and so on. By dint of
necessity, then, whether or not
we are consciously aware of
doing so, we begin to attend to
the subtle nuances or details.
Naturally, when we do so, the
perception changes in the
direction of greater specificity
and precision. Once that
happens, we acquire a family of
slightly different memories
rather than merely the one
undifferentiated memory we
had at the outset. We can then
make separate associations to
each of theseΓÇöΓÇôfor example, a
name. If at this point, when
looking at twins, we notice
that one has a wide nose and
high cheekbones whereas the
other has a narrower nose and
lower cheekbones, we can say
that we perceive the twins
differently.
If this reasoning is correct,
attention is a very important
factor in perception and we
will return to this topic in
more detail shortly. The claim
is not merely that we can bring
this or that object, all of which
are perceived, into the center
stage of awareness. The claim is
that such a manipulation of
attention affects perception
itself.
