The single greatest misconception people have about memory
is that it works like a camera. That would imply that your brain
automatically creates objectively accurate records of everything
it experiences.
Nothing could be farther from the truth. In many cases, your brain
will not remember something until it has interpreted it in a personally
meaningful way. For the most part, remembering something demands
your full, active participation. “Objective memory” is an oxymoron.
Never underestimate your ability to forget. Your whole life —
at age 5, 15, 35 — you’ve demonstrated expert skill at forgetting
things, and you’ll remain that way until the end of your days.
How does it help to know that? For one thing, it changes the questions
you have to answer. Instead of asking “Why do I forget?” maybe
what you should really be asking is “Why do I remember?” That question
has many answers, but if you’re worrying about your memory the
simplest answer is probably this: because you paid attention.
The memory systems of concern here – the ones that most people
are concerned about – are ones that are accessible to consciousness.
Those are the memory systems that handle memories of facts about
the world (sometimes known as “knowledge”) and more personal memories
of doing a certain thing with a certain person at a certain time. The
older you get, the more knowledge you have, for the most part.
So why do people complain about their memory as they age?
In part because it becomes harder for the brain to learn and remember
new things. That seems surprising, in a way. After all, if you remember
things by interpreting them in a personally meaningful way, the more
experiences you have had in your life the easier it should be to
do that. The main reason it becomes harder to learn new things is
that your brain’s processing speed gradually slows. It becomes harder
to do more than one thing at once, so it’s easier to get confused.
Your brain may also become less flexible, so it’s harder to change
learning strategies in mid-stream. All these things mean it becomes
harder to focus.
There’s nothing you can do to change your brain’s processing speed.
So far, researchers haven’t found a way to upgrade your brain’s hard
drive the way you can do with a computer. But there’s a lot you can
do to increase your learning performance even if your processing
speed has slowed. It’s all in the techniques you apply. |
