Did you ever think
that hearts could look be so varied?
And these don't even include
the chocolate hearts we eat!
Most
people can easily recognize these hearts even though they differ in
color, size, orientation, are distorted, overlapping or broken up into
pieces
or
sections. However, individuals who
have perceptual difficulties may not
recognize that these are indeed
all hearts.
Children who demonstrate
perceptual
difficulties may have difficulty
with
puzzles, discriminating different shapes and learning how to read
and write.
Adults who have developmental disabilities, experienced
brain injury, a stroke,
develop dementia or other conditions which
impact brain function may also
demonstrate visual perceptual
difficulties. Some of the specific visual perceptual
skills which
occupational
therapists evaluate are as follows:
Position
in Space- is the ability to
recognize
which direction a shape is
facing and which shapes are
facing the
same direction. For example, which of
these letters are facing in the
same direction as this b ?
d
d
b d
b d
Children
who have
difficulty with
"position in space" discrimination may have
frequent letter reversals
when reading and writing. These hearts are approximately
facing
in the same position in space.
Form
Constancy discrimination
involves recognizing that a shape is the same
even if it is bigger,
smaller, darker, lighter, colored in, an outline or rotated to have
a
different
orientation. Children need to recognize that shapes and letters are the
same in different situations. Many of the hearts above
differ in several attributes,
yet we still recognize them as
hearts. These are all the same hearts regardless
of size or orientation.
Visual Closure discrimination
involves recognizing that
something is the
same even if part is hidden or incomplete. This
enables us to read someone's
handwriting even if the t's
are not
crossed. "Visual closure"
discrimination is
important while doing jig saw puzzles and you
can probably visualize the end
result even before all the pieces are
put in place.You probably know what
shapes these are even though the
lines and pictures are
incomplete.
Figure
ground discrimination
helps us to
discriminate the important details
such as finding the toddler on the
crowded beach. Children who have difficulty
in"figure ground"
discrimination may have difficulty finding a school supply
inside a messy desk or a specific math problem on
a busy page. These hearts
have distracting backgrounds that make
them a bit trickier to
perceive.
Visual Memory How
many of the
hearts up above can you
describe without
scrolling back up? Visual memory is a factor
when
children are required to learn
new skills such as spelling words.
