Theory
on How Memory Functions

Scientists don’t entirely grasp how
the memory organizes. They can’t predict what occurs while recalling a memory. The
brain’s organization and storage of memories have been an infinite journey for
cognitive researchers for decades but have enough theories to formulate
educated guesses regarding the subject.

According to Mohs (2007), the process
of memory starts with encoding, then progress its way to storage and finally,
retrieval. Formation of memory begins specifically through sensory and
perception, and requires paying attention.

            It
will be then stored in short term memory which is known to have small
capacities. Essential learning may be transported to long term memory,
especially when used frequently. Long term memory is known to store unlimited
memories that make it easier to recall when needed. Experts find difficulty in identifying
the difference between true forgetting and failed retrieval of specific
information stored in the long term memory.

Theory
about the Relationship between Short term memory and Long term memory *

 

According to Alison Preston, upgrading
short term memory to long term memory need the help of time have to be
unforgettable for it to become permanent or stay longer in a person’s memory.
Memories have different values.

As memories combine in the storage of
memory it will undergo changes, the longer memories are, the more it becomes
blurry. But if one event have other connections to newer memories, there is a
possibility that these memories will stay longer and still become intact inside
the memory storage.

The process of transferring short term
to long term memory and spreading information through the neurons depends on
the hippocampus (Preston, 2007). The movement of neurons is responsible for
filtering the memories being pushed inside the memory storage. If the neuron
can communicate with another neuron, then there is a possible way for the
memory to have the unforgettable factor and become long term after being in the
short term area. Having the same information on memory to another memory can
help recalling the other one. As time passes, the systems supporting the cells
will become brittle. A person may remember a particular memory but not as clear
as before.

To prove this idea, Preston set old
people who developed dementia or Alzheimer’s disease as an example of memories
fading away through time. There are many ways to prevent this kind of
situations. One important way is to have a good amount of sleep, water and
exercise. Drinking supplements like vitamins to strengthen memory can also
help. Having a good and healthy lifestyle can affect the cells inside a
person’s brain to function well and be able to restore more memories.

 

Theory of Forgetting *

            Why
do people forget their past memories? Many studies are conducted regarding this
topic and different theories have been made such as fading caused by time and
the other is that the memory somehow failed to be retrieved. Experts developed
a theory about forgetting short and long term memory.

The brain’s capacity finds it
difficult to grasp small details at once as suggested by the displacement
theory. The old memories decay and replaced by the newer ones. According to
Murdocks (1962) the short term memory fades due to replacement by the newer
ones or decays because of staying too long over a period of time.

            However,
interference theory says that long term memory can be interfered by the other
memories so it will obliterate the original path of one particular memory.
That’s why doubt sometimes occur when recalling a past memory from a long time
ago. Because of this the information from the original memory will become
edited and not have an assurance. There are two ways of interference that can
cause forgetting. One is proactive interference, where you can learn other
informations because it will flourish other informations that is inside your
mind. The second one is the retroactive interference. Where you will fully
forgot your memory because of your current memory. For example when you have a
new phone number, you will have to memorize it, and because you have another
number, you will not need to remember your past number. It will be forgotten
because you created a new one.
