I had the opportunity to take a social gerontology class a few years
ago, that was mostly aimed at students who might be working with
senior citizens, with an aging population, etc. But there were some
really great resources the instructor brought in that made me realize
how important it is to look at exhibits or programs from the point of
view of a specific audience.
One of my favorite parts of the class was an exercise that was led by
a woman from the local Council on Aging. We were handed out various
set of glasses (that ranged from slightly scratched, to mostly
blacked out) to simulate different vision problems. We put cotton
balls in our ears. We tied a string around our ankles to impose a
shorter gait. And we put on latex gloves to simulate the loss of
touch sensitivity. In the context of the exercise (of us being in a
senior "daycare", with a snotty, condescending "aide" to help us), I
remember how frustrated I got very quickly. At being expected to sign
a check when I couldn't even see the signature line, at being told to
"hurry along" when I could only take steps that were a foot apart. It
gave me a very different outlook on the point of view of a person
with some physical challenges.
We also had an exercise that simulated the type of hearing loss that
is common - not of overall volume decrease but of a decrease in
hearing the upper frequencies (where consonant sounds hang out!).
This meant that turning up a volume dial did nothing to increase
comprehension. Just try figuring out what someone is saying if you
can only hear vowels.
Other considerations that were brought up were to have adequate
access to seating (for resting) and restrooms.
The last thing that comes to mind dealt with vision changes - that
led to certain colors standing out less (again, not a problem of
turning up a volume, because only certain frequencies were affected).
This category also included leaving more time for dark-adaptation and
light-adaptation (since the eyes get slower at this as we age), and
planning times of day for certain programs because of decreased night
vision (and a harder time driving at night).
Taken all together, these changes describe a person who may not even
be up and about, but as a set of things to keep in mind, they may
make a difference for aging visitors.
On a final (and maybe more positive) note, I did my term paper for
the class on a researcher named Paul Baltes, who studied cognitive
changes of aging brains. Although computational speed was decreasing
on average, some of his research showed that wisdom was increasing
with age for many people. How exactly to harness or engage an
increasingly wise mind is a tough question, and I remember wondering
how this might be taken advantage of with programs that looked at
this aspect of human reasoning.
