(ITP-16) Forgetting: Nature, causes, theories and disorders
Abstract: This article provides a comprehensive
overview of forgetting, including its nature, causes, and related disorders.
Forgetting is the inability to retrieve previously stored information from the
memory, and it can happen due to various factors such as decay, interference,
and retrieval failure.The
article also explores various theories of forgetting, including decay theory,
interference theory, and retrieval failure theory. Additionally, forgetting can
be a symptom of disorders such as amnesia, Alzheimer's disease, and dementia.
The article also provides techniques to improve memory retention, such as
rehearsal, chunking, association, and visualization. Furthermore, factors such
as age, stress, sleep deprivation, and medication can also influence
forgetting. Finally, when forgetting becomes a problem, seeking professional
help is important, as forgetting can be a symptom of depression, anxiety, and
ADHD.
Have you ever forgotten something important, like a friend's
birthday or a meeting with your professor? Or perhaps you have struggled to
recall an answer during a test, even though you studied extensively for it.
These experiences are common and frustrating, but they are also part of a
natural process known as forgetting.
What is forgetting?
Forgetting is the inability to retrieve information that was
previously stored in the memory. This can happen for various reasons, including
decay, interference, and retrieval failure. Decay refers to the gradual fading
of memory traces over time. Interference happens when new information
interferes with the retrieval of older information. Retrieval failure occurs
when we are unable to access stored information due to inadequate cues or
context.
Causes of Forgetting
written in Theories:
Various theories have been proposed to explain the causes of
forgetting. Here are some of the most prominent theories and their authors:
a.
Decay Theory by
Ebbinghaus: This theory suggests that forgetting occurs due decay. Decay
is the fading of memory traces over time. If we do not use or reinforce the
memory traces, they will eventually be deleted.
b.
Interference Theory by
Muller and Pilzecker: This theory suggests that forgetting occurs
due to interference from other memories. Interference occurs when new
information interferes with the retrieval of older information. Interference can
happen in two ways:
·
Retroactive interference: new information
interferes with the retrieval of old information.
·
Proactive interference: old information
interferes with the retrieval of new information.
c.
Retrieval Failure
Theory by Tulving and Thomson: This theory suggests that forgetting
occurs due to Retrieval failure. Retrieval failure happens when we are unable
to retrieve information due to inadequate cues or context. This can happen when
we lack the necessary information or cues to access a particular memory.
d.
Motivated Forgetting
Theory by Sigmund Freud: This theory suggests that forgetting occurs
when we repress or suppress unpleasant or unwanted memories to protect
ourselves from psychological harm.
e.
Encoding Failure
Theory by Craik and Lockhart: This theory suggests that forgetting
occurs due to inadequate encoding of information. If we do not encode
information properly, it will not be stored in the memory.
Understanding these theories can help us better understand the nature of forgetting and develop strategies to improve memory retention.
Disorders related to forgetting
Forgetting can also be a symptom of various disorders, such
as:
- Amnesia: Amnesia
is a condition where an individual is unable to remember past events or
form new memories. It can be caused by head injuries, strokes, or
degenerative diseases.
·
Retrograde amnesia is a type of amnesia where
a person is unable to remember events that occurred before the onset of
amnesia.
·
Anterograde amnesia, on the other hand, is a
type of amnesia where a person is unable to form new memories after the onset
of amnesia.
- Alzheimer's
Disorder: Alzheimer's Disorder is a progressive brain disorder
that affects memory, thinking, and behavior. It is the most common cause
of dementia in older adults.
- Dementia:
Dementia is a general term for a decline in cognitive function that
interferes with daily life. It can be caused by various conditions,
including Alzheimer's disease, Parkinson's disease, and Huntington's
disease.
How to improve memory retention
Although forgetting is a natural process, there are various
techniques that can improve memory retention, such as:
- Rehearsal:
Rehearsal involves repeating information to reinforce memory traces.
- Chunking:
Chunking involves grouping information into smaller units to make it
easier to remember.
- Association:
Association involves linking new information to existing knowledge or
memories.
- Visualization:
Visualization involves creating mental images to aid memory retention.
Factors of Forgetting: Forgetting can be
influenced by various other factors such as age, stress, sleep deprivation, and
medication.
·
As we age, our memory and ability to retain new
information may decline.
·
Stress and sleep deprivation can also affect
memory, as they can interfere with the encoding and consolidation of new
information in the memory.
·
Certain medications such as tranquilizers,
sedatives, and antihistamines can also affect memory and lead to forgetting.
Forgetting is not always bad: It is important
to note that forgetting is not always a bad thing. In fact, forgetting can be a
useful process that helps us filter out irrelevant information and focus on
what is important. Forgetting also allows us to update our knowledge and adapt
to new situations.
Professional help for Forgetting: When
forgetting becomes a problem and interferes with daily life, it is important to
seek professional help. Forgetting can be a symptom of various disorders such
as depression, anxiety, and ADHD. These conditions can affect memory and lead
to forgetting, along with other symptoms such as difficulty concentrating, low
mood, and anxiety.
Conclusion:
In summary, forgetting is a natural process that can occur
due to various reasons. Memory is a complex system that can be influenced by
various factors. Understanding the causes of forgetting and the techniques to
improve memory retention can help in retaining important information. However,
when forgetting becomes a problem and interferes with daily life, it is
important to seek professional help.
