Introduction to Memory

Introduction to Memory What Is Memory? How Memories Are Formed? How Long Do Memories Last? Why we forget? What are noted problem with memory? Using Memory Organising Memory Processes Of Memory Anatomy Of Memory Tips To Improve Memory

What is Memory?

What is Memory? Memory refers to the processes that are used to acquire, store, retain, and later retrieve information. There are three major processes involved in memory that are encoding, storage , and retrieval . Human memory involves the ability to both preserve and recover information we have learned or experienced. As we all know, however, this is not a flawless process . Sometimes we forget or misremember things. Sometimes things are not properly encoded in memory in the first place.

How long do memories last?

How Long Do Memories Last? Some memories are very brief , just seconds long, and allow us to take in sensory information about the world around us. Short-term memories are a bit longer and last about 20 to 30 seconds. These memories mostly consist of the information we are currently focusing on and thinking about. Some memories are capable of enduring much longer, lasting days, weeks, months, or even decades. Most of these long-term memories lie outside of our immediate awareness, but we can draw them into consciousness when they are needed.

Why we forget?

Why we forget? Forgetting is a common problem that can have both minor and serious consequences. Why and how do we forget information? One of today's best known  memory  researchers,   Elizabeth Loftus , has identified four major reasons why people forget: R etrieval failure. I nterference. F ailure to store. M otivated forgetting.

Why we forget? R etrieval failure. One possible explanation of retrieval failure is known as D ecay theory . According to this theory, a memory trace is created every time a new theory is formed. Decay theory suggests that over time, these memory traces begin to fade and disappear. If​ the information is not retrieved and rehearsed , it will eventually be lost. I nterference. I nterference theory suggests that some memories compete and interfere with other  memories . When information is very similar to other information that was previously stored in memory, interference is more likely to occur. There are two types of interference Proactive interference  is when an old memory makes it more difficult or impossible to remember a new memory. Retroactive interference  occurs when new information interferes with your ability to remember previously learned information

Why we forget? F ailure to store Sometimes, losing information has less to do with forgetting and more to do with the fact that it never made it into long-term memory in the first place. Encoding failures  sometimes prevent information from entering long-term memory. M otivated forgetting. Sometimes we may actively work to forget memories, especially those of traumatic or disturbing events or experiences. Painful memories can be upsetting and anxiety-provoking , so there are times we may desire to eliminate them. The two basic forms of motivated forgetting are  suppression , which is a conscious form of forgetting, and repression , an unconscious form of  forgetting

Problems with memory

Problems Associated with Memory Memory problems can be as: Minor Annoyances like forgetting where you left your bike keys. Major Diseases like Alzheimer's and other kinds of dementia. Mental health condition: Memory is also a key element in certain mental health conditions . P ost-traumatic stress disorder . M ajor depression .

Using Memory

Using memory To use the information that has been encoded into memory, it first has to be retrieved. There are many factors that can influence how memories are retrieved such as the type of information being used and the retrieval cues that are present. Of course, this process is not always perfect . Have you ever felt like you had the answer to a question right at the tip of your tongue , but you couldn’t quite remember it? This is an exampl e of a perplexing memory retrieval problem known as lethologica or the tip-of-the-tongue phenomenon .

Organising Memory

Organising Memory The ability to access and retrieve information from long-term memory allows us to actually use these memories to make decisions, interact with others, and solve problems. But how is information organized in memory? One way of thinking about memory organization is known as the semantic network model. This model suggests that certain triggers activate associated memories. A memory of a specific place might activate memories about related things that have occurred in that location.

Organising Memory Some ways to Organise Memory Are: Steady Improvement Trust Your Memory Believe In Yourself Face Facts Map Your Memories

Processes Of Memory

Processes Of Memory There are three processes of Memory: Encoding, Storage, and Retrieval. All three of these processes determine whether something is remembered or forgotten.

Encoding: “Processing information into memory is called Encoding”. Automatically Remembered- e.g Where ate lunch yesterday? Pay Attention To Remember- e.g Deep study to remember course contents.

Types of Encoding There are several different ways of encoding verbal information: Structural or Visual Encoding : Focuses on what words look like. Phonemic or Acoustic Encoding : Focuses on how words sound. Semantic Encoding : Focuses on the meaning of words.

Storage After information enters the brain, it has to be stored or maintained. To describe the process of storage, many psychologists use the three-stage model proposed by Richard Atkinson and Richard Shiffrin . According to this model, information is stored sequentially in three memory systems: sensory memory, short-term memory, and long-term memory.

Retrieval “Retrieval is the process of recalling stored information from memory. Basically it is getting information out of your long term memory and returning it to your conscious mind”.

Retrieval Cues “ Retrieval Cues are stimuli that help the process of retrieval”. Associations : Because the brain stores information as networks of associated concepts, recalling a particular word becomes easier if another, related word is recalled first. This process is called Priming. Context : People can often remember an event by placing themselves in the same context they were in when the event happened. Mood : If people are in the same mood they were in during an event, they may have an easier time recalling the event.

Methods of Retrieval There are two main methods of retrieving memories: Recognition : It is the association of something with something previously experienced. It involves comparing new information with information stored in memory. Recall : It is the retrieval of information from the memory without any cue. It involves remembering a fact, event or other information which is not currently physically present.

Anatomy of Memory The main parts of the brain involved in memory are: Amygdala Hippocampus Cerebellum Thalamus Prefrontal Cortex

Amygdala Plays role in formation of new memories,memory consolidation and modify the strength of emotional content of memories. Hippocampus Hippocampus plays a critical role in the formation, organization, and storage of new memories as well as connecting certain sensations and emotions to these memories. Cerebellum The cerebellum plays a role in processing procedural memories, such as how to play the piano Thalamus Thalamus plays a crucial role in sustaining short-term memory and also plays role in working memory. Prefrontal Cortex The prefrontal cortex appears to be involved in remembering semantic tasks.

Tips To Improve Memory

Tips To Improve Memory No matter how great your memory is, there are probably a few things you can do to make it even better. Jot it down Attach Meaning to it Repeat it Avoid Cramming Utilise Mnemonics Devices

Factors of Memory

Factors of Memory Learning : Memory depends upon learning. It is not possible to keep memorized any thing without learning. Learning mechanically have significance in learning. by understanding and learning Retention : Keeping the learnt things in the rain is its retention. If the retention power of a person is weaken, his related memory also weaken. There are found individual difference in the retention power

Factors of Memory Recall Remembering a prior experience is its recall. Recall is such a mental process by which we bring to our present consciousness the past incidents and experiences without presenting a physical stimuli. Recall classified into two: Natural or Dispositional : Natural recall occurs by itself when we let the thought flow freely, any thought can come to the mind. Reflective or Deliberative : here the thOught occur to the mind on making effort. recall the answer pertaining to the question given to the question paper. Eg. student

Factors of Memory a. Ability to retain: • This depends upon good memory traces left in the brain by past experiences. b. Good health: A person with good health can retain the learnt material better than a person with poor health. c. Age of the learner: Youngsters can remember better than the aged. d. Maturity: Very young children cannot retain and remember complex material.

Factors of Memory e. Will to remember: Willingness to remember helps for better retention. f. Intelligence: • More intelligent person will have better memory than a dull person, g. Interest: • If a person has more interest, he will learn and retain better. h. Over learning: Experiments have proved that over learning will lead to better memory. i. Speed of learning: • Quicker learning leads to better retention,

Factors of Memory j. Meaningfulness of the material: Meaningful materials remain in our memory for longer period than for nonsense material, k. Sleep or rest: Sleep or rest immediately after learning strengthens connections in the brain and helps for clear memory.

Types of Memory

Types of Memory There are Three types of memory: Sensory Memory(fraction) Short term Memory(STM) Long term Memory(LTM)

Sensory Memory Based upon fractions of seconds Brief Memory First stage of Memory Store info. For very brief period

Short Term Memory(STM) Second stage of multistore memory Duration of STM between 15-30 Second Capaciy about 7 items Working Memory Can be transferred to LTM

Long Term Memory(LTM) Brain’s sytem for storing managing and retrieving information More complex than STM Includes life experiences Store info. Over an extended period Refers as life time memory

Types of STM and LTM STM : Woking Memory Auditory/Verbal Memory Visual-Spatial Memory LTM Implicit Memory Explicit Memory Autobiographical Memory

Types of STM : Working Memory : Subpart of short term memory Temporarily stores, organizes and manipulates informaion

Auditory/Verbal Memory: Linked with audio-verbal senses Ability to listen info. presented orally Encoding verbal info. Repeting immediately

Visual-Spatial Memory : Involves visual sense Ability to recall shapes, colors and places and movement Skill helps children in learning

Types of LTM : Implicit Memory : Remembered unconsiously and effortlessly Effects thoughts and behaviour Allow someone to do things in repeating manner E.g: childhood memories even in old age

Subtypes of Implicit Memory Procedural Memory : Recall of how to perform an action,task or skills

Explicit Memory : Concious , Intentional, and, Remembring of information

Subtypes of Explicit Memory : Declarative Memory : Recall of factual info. Such as dates ,word, faces and concepts E.g: Remebring the rule of last game currently happened It is divided in two subtypes: 1: Episodic Memory 2:Semantic Memory

1: Episodic Memory 2:Semantic Memory 1: Episodic Memory : Recall of personal experience E.g : remebring what happened in your B’da party or baseball game 2: Semantic Memory : Recall of general facts E.g : Remebring the Capital of UK & batting average of S. Tendulkar
