The mind works in a similar manner as a computer. This |
|
|
is in the manner in which it stores information which it |
|
|
finds as important in ways similar to files. This memory |
|
|
is not always perfect, and its function diminishes as |
|
|
people get older. Memory can be defined as a process |
|
|
whereby information on our experiences is stored which |
|
|
we then recover when we recollect them. We often forget |
|
|
things, and this is normal. But some ways in which |
|
|
things are forgotten are an indication of more serious |
|
|
problems. For instance, experiencing difficulties in |
|
|
finding the way home or forgetting such a basic thing as |
|
|
using the telephone can indicate serious problems. |
|
|
Neurologists have divided memory into two divisions: |
|
|
short term memory or STM, also known as working memory, |
|
|
and long term memory or LTM. Short term memory works |
|
|
like the virtual memory in a computer, as it remembers |
|
|
the information in use. Studies have shown that most |
|
|
people put between five and nine items in their short |
|
|
term memories at any given time. Trying to remember more |
|
|
than that causes forgetfulness of some items. In STM, |
|
|
the cerebral cortex of the brain recognizes nerve |
|
|
messages from organs such as the eyes and ears, as well |
|
|
as the touch sensors. The sensory memory holds this |
|
|
sensory stimulus for a fraction of a second. If the |
|
|
individual pays attention to this image for a period of |
|
|
eight consecutive seconds, the stimulus is encoded into |
|
|
the short term memory, failure to which the image is |
|
|
lost. Thereafter, the memory is stored in something |
|
|
similar to an electronic tape loop. When something |
|
|
similar to the completion of a loop is made, one of |
|
|
three things may take place: One, the information can be |
|
|
repeated, either silently or aloud, or it can go into |
|
|
long term memory, or, lastly, the information can be |
|
|
lost. |
|
|
Long term memory is the part of our memory having |
|
|
unlimited capacity for storing information and it can be |
|
|
for an extended period of time. The LTM represents three |
|
|
kinds of memory: 1) procedural memory, which is memory |
|
|
that represents skill learning motor or learning such as |
|
|
tying your shoelace. 2) Declarative memory which is a |
|
|
memory for facts. It acquires memories, such as names |
|
|
and dates, fast and loses them fast as well. 3) Remote |
|
|
memories are memories that were collected early, and |
|
|
which form the basis of more recent memories. This kind |
|
|
of memory is therefore easily changed or lost. |
