Memory and Forgetting: NBSE Class 12 Education

Summary

Memory is our mind’s ability to hold on to information and experiences. It allows us to remember our friends, family, and things that happened long ago. This gives us a sense of connection between our past and present. Memory involves four main steps. The first is learning or registering new information. The second is retention, which is storing that information. The third is recall, which means bringing the information back to mind. The fourth is recognition, which is identifying something when you see it again.

There are different ways to learn and remember things. Learning with breaks in between is often more effective than trying to learn everything at once. We can also use special tricks to help us remember, such as making a word from the first letter of each item in a list. When we learn something, it creates a ‘memory trace’ in our brain. This is like making a footprint in the sand. A deep footprint will last a long time, just as a strong memory does. A weak footprint will fade away, just like a weak memory. We can measure how well we have retained something by trying to recall it, recognize it, or see how quickly we can relearn it.

Information moves through different stages in our memory. First, it enters our sensory memory for just a fraction of a second. If we pay attention to it, the information moves to our short-term memory. This holds a small amount of information for about thirty seconds. It is like a temporary notepad for things like a phone number you are about to use. If we keep rehearsing or thinking about the information, it can be moved to our long-term memory. This is a vast storage space for information that we can keep for years, like facts we learned in school or memories of special events.

Forgetting is a normal process and is the opposite of remembering. Sometimes we forget because the memory trace, or the ‘footprint’, fades away over time if we do not use the memory. This is called decay. We also forget because of interference, which is when other memories get in the way of the one we are trying to recall. For example, learning a new song might make it hard to remember the words to an old one. People may also forget unpleasant or painful experiences because they do not wish to remember them. Other things like poor health, strong emotions, or being in a completely different environment can also make it difficult to remember.

Very Short Answer Questions

1. Expand the terms: (a) LTM (b) STM

Answer: (a) LTM stands for Long-Term Memory.

(b) STM stands for Short-Term Memory.

2. What is recall?

Answer: Recall is the third factor of memory. It means the presentation of any past experience in the form of an image or language in the conscious level of the mind. It involves the association of ideas.

3. What is memory?

Answer: According to Woodworth and Marquis, memory is mental power which consists of learning, retaining, and remembering what has previously been learnt. It is the special ability of our mind to store what we learn to recollect and reproduce it after some time, and is a complex process involving learning, retention, recall, and recognition.

4. List the different stages of memory.

Answer: According to the most acceptable model of memory, there are three major systems or stages of memory:

Sensory Memory
Short-Term Memory (STM)
Long-Term Memory (LTM)

5. Define forgetting.

Answer: According to Munn, forgetting is the loss, permanent or temporary, of the ability to recall or recognise something learned earlier.

6. State any two causes of forgetting.

Answer: Two causes of forgetting are:

Emotions: A rise in emotions like fear, anger, or love can lead to forgetting learned experiences. For example, a student who is afraid of a teacher may forget what has been learnt.
Poor Health: This prevents us from remembering the learnt material.

Short Answer Questions

1. How can forgetting be minimised?

Answer: Forgetting can be minimised by reducing interference. Since interference is a major cause of forgetting, one should try to reduce it as much as possible. Generally, the more similar the materials to be learned, the more likely they will produce interference. Thus, one should arrange studies so that similar subjects are not studied one right after the other. For example, if two languages have to be studied, they should be studied on different days.

Forgetting can also be minimised through distributed practice, which means learning material with a gap between trials and taking rest after a period of study. Instead of cramming all information at once, if a chapter is lengthy, it should be divided into parts and learned one part at a time.

Finally, repetition and continuous practice add to the effectiveness of memorisation. Intelligent repetition with full understanding helps in making learning effective and enduring, and things that are repeated and practiced frequently are remembered for a long time.

2. Discuss different types of memory with examples.

Answer: The different types of memory are:

Immediate Memory: This is also known as short-term memory. It is when an individual has to reproduce something immediately after learning it, so the time span is very less for the matter to be registered in the consciousness. The learned matter is forgotten rapidly. For example, we may first look at the seat number of our ticket, and once we sit down, we forget about it. In this type of memory, the retention time is very brief.

Short-term memory: This type is also called temporary memory and is not as short-lived as immediate memory. The information temporarily stored in short-term memory may last as long as thirty seconds even if the material is not being rehearsed. Some people can retain more information in short-term memories through a process called chunking, which groups information by coding it. For example, the number 143254376 can be remembered by listing it under three heads: 143, 254, 376.

Long-term memory: This is also known as permanent memory. Here, the individual learns and retains information for a very long period. There is an interval of time between learning and recall or reproduction. Permanent memory is involved in, for example, knowing our bank account number or phone number.

3. Explain the components of memory.

Answer: Memory is a mental ability that involves four different factors or processes. These components are:

Registration or Learning: This is the first factor in the process of memory. Learning is the acquisition of new information or experiences, which leads to the establishment of an association of ideas in the mind. This factor is the way to register the first impression of an object or idea, without which memorisation cannot take place.

Retention: This is the stage that follows learning, making the learning permanent. Retention is the inactive state of learned activity. The learning activity leaves a mark on the brain structure called a ‘Memory Trace’, which is imprinted on the Cerebral Cortex. This preservation of the memory trace is the retaining of the learning activity.

Recall: This is the third factor of memory. It means the presentation of any past experience in the form of an image or language in the conscious level of the mind. It involves the association of ideas.

Recognition: This is the fourth factor of memory. It is the capacity to be aware of a previous experience. If a person can identify an ‘object or idea’ at present of which he or she has a past experience, it is called ‘recognition’.

4. Enumerate with examples, the different ways in the process of memorising.

Answer: The different ways in the process of memorising are:

(a) Rote Memorisation: This is learning without understanding. Meaningful material is more easily learned than nonsense material. For example, it is easier to learn poetry than prose, and prose is easier to learn than disconnected words.

(b) Spaced v/s Mass Learning: In spaced learning, the learner is allowed rest during memorisation, following the principle of ‘work and rest’. In mass learning, the subject memorises the material in one sitting without any interval until it is mastered.

(c) Whole v/s Part Method of Learning: In the whole method, a poem, for example, is read again and again from start to finish. In the part method, the poem is broken down into parts or stanzas and then learned, which benefits slow learners and average students.

(d) Recitation: This is a method where the student reads a lesson a few times and then reviews it without the book by reciting the material learned. This helps in achieving permanent retention.

(e) Mnemonic devices: These are artificial associations made to associate ideas or material. For example, grouping helps to memorise easily. Memory improved by using artificial associates is called Mnemonics.

5. List two main differences between short term and long term memory.

Answer: Two main differences between short-term and long-term memory are:

The first difference is the duration of retention. Short-term memory holds information for brief periods, usually 30 seconds or less, and the information may last only as long as thirty seconds if not rehearsed. In contrast, long-term memory is for the retention of information for longer periods of time, allowing us to remember events that happened many years ago.

The second difference is the amount of information held. Short-term memory holds relatively small amounts of information. Long-term memory, on the other hand, is the memory system for the retention of large amounts of information.

6. What are the causes of forgetting?

Answer: The causes of forgetting are:

Faulty Memory Process: Sometimes, we encode only a portion of information as a gist, not the actual words or details. The constructive process during encoding can distort what is stored, and we remember these distortions. Our memory does not match the events as they actually occurred.
Interference: An important cause of forgetting is the interference of learned material. There are two kinds: proactive inhibition, where earlier learning interferes with later learning, and retroactive inhibition, where later learning inhibits the recall of earlier learning.
Retrieval Problems: Retrieval is necessary for recall. Without appropriate retrieval cues or remainders to direct the memory search to the right part of the long-term memory, the sought-for items may not be found, leading to forgetting.
Motivated Forgetting: This is a kind of forgetting where an individual intentionally forgets. The information is stored but the individual does not want those memories and represses them. Generally, people remember pleasant experiences more than unpleasant ones.
Amnesia: This refers to a loss of memory and is a kind of memory disorder. It can be psychological, caused by disturbances in encoding, storage, and retrieval, or biological, caused by abnormal functioning of the brain due to injury, drugs, or disease.

Long Answer Questions

1. Differentiate between recall and recognition.

Answer: Recall and recognition are two different factors of memory.

Recall is the third factor of memory and is a direct method of testing retention. It means the presentation of any past experience in the form of an image or language in the conscious level of the mind. Recall finds the object from the mind and depends on the mental condition and the memory trace formed. It is considered an active process. However, sometimes we are not able to recall, even when we know the matter, so this is the poorest retention score of all that is learnt.

Recognition is the fourth factor of memory and is the capacity to be aware of a previous experience. It means familiarity with something, or the ability to judge whether something is identical with a perceived experience on an earlier occasion. Recognition starts with the object given, whereas recall finds the object from the mind. It is easier to recognise than to recall, and recognition is better than recall as an index of retention. Recognition is more of a passive behaviour than an active process like recall.

2. What are the factors which are responsible for influencing one’s memory?

Answer: There are four different factors or processes in memory which are responsible for influencing it. They are:

Registration or Learning: This is the first factor of the process of memory. It is the acquisition of new information of experiences which leads to the establishment of the association of ideas in mind. This factor is the way to register the first impression of an object or idea without which memorisation cannot take place. Before remembering, it must be registered or learnt.

Retention: The process of learning involves the stage of retention, thus learning becomes permanent. Retention is the inactive state of learnt activity. The learning activity leaves a mark on the brain structure called a ‘Memory Trace’. This preservation of the memory trace in the brain is the retaining of the learning activity.
Recall: The third factor of memory is recall. It means the presentation of any past experience in the form of an image or language in the conscious level of the mind. It involves the association of ideas.
Recognition: Recognition is the fourth factor of memory. It is the capacity to be aware of a previous experience. If a person can identify an ‘object or idea’ at present of which he/she has a past experience, it is called ‘recognition’.

3. Suggest some steps to improve memory. Could it be sharpened? Justify.

Answer: Yes, memory can be improved. It is possible with little effort and almost anyone can improve his or her memory.

Memory consists of four factors: Registration or Learning, Retention, Recall, and Recognition. Improvement in any one or more of these constituents is likely to improve the memory as a whole. Out of these four, learning and recall can be improved by training. Actually, improvement in memory demands the necessary improvement in the techniques and methods of learning, the learning situation and environment, and the learners’ state of mind.

Some tips and techniques to enhance one’s memory are:

Intention to Learn: Firm determination or strong will to learn is required to achieve success. Materials read, heard, or seen without intention or mood are difficult to be remembered at later times.
Deep Processing: To learn something and enter information into long-term memory, you have to think about it. You need to consider its meaning and examine its relationship to information you already have. The retention of material is dependent directly upon the depth at which it has been processed.
Interest and attention: To learn something well and ensure its retention in long-term memory you have to put in conscious effort to attend to it carefully. A person who has no interest in what he learns will not give due attention to it and consequently will not be able to learn it.
Minimise interference: You should try to reduce interference as much as possible. You should arrange your studies so that you don’t study similar subjects one right after the other. For example, if you have to study two languages, study them on different days.
Distributed practice: While learning some material it is beneficial to learn it using distributed practice in which there is a gap between trials. If a chapter is lengthy, divide it into two or three parts and learn a part in one go. Do not try to cram all the information you want to memorise at once.
Using memory aids: People use various cues, indicators and signs to connect events. You can use visual imagery to remember objects and places. For example, you may remember a location by remembering several associated objects and places.
Shorthand codes: You can develop your own shorthand codes to memorise long lists of items. You can use the first letter of each word or item and construct a unique “word”. For example, to remember the seven constituents of light we use VIBGYOR.
Meaningfulness: If the subject matter taught to students is meaningful and it has been presented to them in an organised manner, it will be retained for a longer period of time.
Grouping and rhythm: Grouping and rhythm also help and facilitate learning and help in remembering. For example, a telephone number is learnt well when digits are grouped.
Repetition and recitation: Repetition and continuous practice add to the effectiveness of memorisation. Intelligent repetition with full understanding always helps in making learning effective and enduring.
Internal factors within the learner: His/her physical and mental health and state of mind at the time of learning as well as reproduction counts a lot to memory. Due attention should be given to the improvement of the student’s health—physical as well as mental.
Making use of SQ4R Techniques: This strategy for effective learning and memorisation involves Survey, Question, Read, Reflect, Recite and Recall, and Review.

4. What are the different ways to minimise forgetting?

Answer: Forgetting can be minimised by adopting certain strategies that improve learning and retention. The different ways to minimise forgetting are:

Minimise interference: Interference is a major cause of forgetting. To reduce it, you should arrange your studies so that you don’t study similar subjects one right after the other. For example, if you have to study two languages, study them on different days.
Deep Processing: The retention of material depends on the depth at which it has been processed. To minimise forgetting, you should think about the information, consider its meaning, and relate it to existing knowledge. Greater rehearsal also reduces the chances of forgetting.
Ensure Interest and Attention: A person who has no interest in what he learns will not give due attention to it and will forget it. Therefore, to minimise forgetting, one must put in a conscious effort to attend to the material carefully.
Use Distributed Practice: Instead of cramming information all at once, it is beneficial to learn it using distributed practice, with gaps between trials. Taking rest after a period of study and dividing lengthy chapters into parts helps in better retention and minimises forgetting.
Engage in Repetition and Recitation: Repetition and continuous practice add to the effectiveness of memorisation. Things repeated and practiced frequently are remembered for a long time, thus minimising forgetting. Self-recitation is better and more time-saving than just reading and rereading because permanent retention is achieved.
Maintain Good Internal Factors: A learner’s physical and mental health and state of mind affect memory. To minimise forgetting, attention should be given to improving one’s health. A fresh mind is able to learn more and retain it for a longer time than a tired and dull one.

5. Discuss the causes related to storage failure for forgetfulness.

Answer: Storage failure, where information that has been stored in memory is lost, is a key reason for forgetfulness. The causes related to this failure include:

Theory of Decay: This theory suggests that forgetting is a process of the fading of learnt matter with the passage of time. Vivid impressions or memory traces created in the cerebral cortex fade away as time passes. This decay could be a result of the normal metabolic processes of the brain, which might cause the traces of material once learned to disintegrate gradually and eventually disappear altogether. This is also known as the Trace Decay Theory, which states that if learnt processes are not used for a long time, the traces get faded.
Interference of Association: According to this theory, forgetting is caused by the influence of intervening activities. When more and more memory traces are formed, some overlapping of traces can take place, resulting in obliteration and interference. This means one learning will interfere with or inhibit the memory process of another, leading to a failure to maintain the original stored information.
Amnesia: Amnesia refers to a loss of memory and occurs from a loss of what has already been stored. Biological amnesia is a type of storage failure caused by abnormal functioning of the brain. This abnormality may be due to causes such as a blow on the head, temporary disturbances in blood supply to the brain, certain drugs, brain diseases like Arteriosclerosis and Alzheimer’s disease, and chronic alcoholism. These problems can result in a profound memory loss, indicating a failure of the storage system.
Faulty Memory Process: Sometimes, distortions occur during the process of encoding information. A constructive process at work during encoding distorts what is stored in memory. In this case, what is stored is not an accurate representation of what really happened. This is a failure related to storage because the information itself is stored incorrectly from the beginning.

Registration or Learning
Retention
Recall
Recognition

39. Explain the difference between Rote Memorisation and meaningful learning.

Answer: Rote Memorisation is learning without understanding. In contrast, meaningful material is more easily learnt than nonsense material. If the subject matter taught is meaningful and presented in an organised manner, it will be retained for a longer period of time.

40. When is mass learning more effective than spaced learning?

Answer: Mass learning is effective when the pupils are very intelligent or are highly motivated.

41. Explain the ‘Whole v/s Part Method of Learning’ with an example.

Answer: The ‘Whole v/s Part Method of Learning’ involves two approaches. In the whole method, a task is learned by practicing it from start to finish repeatedly. For example, a poem is read again and again from start to finish. This method is suitable when the material is not very lengthy and is logically arranged.

In the part method, the task is broken down into smaller sections. For example, a poem is broken down into parts or stanzas, and each part is learnt separately before the whole content is mastered. This method benefits slow learners and is useful when the material is large and not well organised.

42. Why is self-recitation considered a better method of learning?

Answer: Self-recitation is considered a better and time-saving method of learning than just reading and rereading because permanent retention is achieved. Through self-recitation, the learner is able to detect his or her weakness and is able to rectify them. This way, the learner also knows his or her progress.

43. How can retention be measured? Name the three ways.

Answer: Retention can be measured in three ways:

Recall
Recognition
Relearning

44. Why is relearning considered the best method to measure retention?

Answer: Relearning is considered the best method to measure retention compared to recognition and recall methods. Even if we may not recall or recognise the material learnt once, if we learn it again, we can pick it up very soon, understand, and master it. A person may consume much less time and a reduced number of trials to relearn something, which indicates that retention has taken place.

45. Differentiate between immediate memory and short-term memory.

Answer: Immediate memory is when an individual has to reproduce something immediately after learning it, with a very brief retention time, causing the learnt matter to be forgotten rapidly.

Short-term memory is not as short-lived as immediate memory. Information temporarily stored in short-term memory may last as long as thirty seconds even if the material is not being rehearsed.

46. What is long-term memory? Provide an example.

Answer: Long-term memory, also known as permanent memory, is where an individual learns and retains information for a very long period of time. An example of permanent memory is knowing our bank account number or phone number.

47. What are the three major systems of memory in the accepted model?

Answer: According to the most acceptable model of memory, the three major systems of memory are:

Sensory Memory;
Short-Term Memory (STM), and
Long-Term Memory (LTM).

48. What is Sensory Memory? How long does a visual image last in it?

Answer: Sensory memory holds representations of sensory input for very brief periods of time, depending upon the modality involved.

A clear visual image of any object will last in sensory memory for about half a second after the stimulus is removed.

49. What is the role of rehearsal in transferring information to LTM?

Answer: Information from Short-Term Memory (STM) is often rehearsed. This rehearsal helps the transfer of that information from STM to Long-Term Memory (LTM). For example, if we keep dialling a telephone number repeatedly, the rehearsal pushes it to the long-term memory (LTM) storage.

50. Why is short-term memory also called “working memory”?

Answer: Short-term memory is also called “working memory” because it has been found that short-term storage is more than a passive “holding area.” It involves the active processing of information, which means that something active goes on during short-term memory.

51. List any four characteristics of a good memory.

Answer: A good memory has certain characteristics. They are:

When a person can easily and rapidly learn a material, it definitely shows a good memory as he is relating it to a material learnt earlier.
An individual with good memory means that he can retain the maximum amount of learnt material in his/her mind.
Another sign of good memory is easy recall.
Clear and quick recognition is a sure sign of good memory.

52. How does ‘Intention to Learn’ affect memory and retention?

Answer: A firm determination or strong will to learn is required to achieve success. When the same material is given to students, retention is greater in those who have a determination to learn compared to those who are unwilling. Materials read, heard, or seen without intention or mood are difficult to be remembered at later times.

53. Explain the quote: “Interest is the mother of attention…”.

Answer: The quote, “Interest is the mother of attention and attention is the mother of memory if you would secure memory, you must first catch the mother and the grandmother,” means that interest and attention are essential for useful learning and memorisation. A person who has no interest in what he learns will not give due attention to it and consequently will not be able to learn it. Therefore, to secure memory, one must first have interest (the grandmother), which leads to attention (the mother).

54. How can interference be minimised while studying?

Answer: Interference can be minimised by arranging studies so that similar subjects are not studied one right after the other. In general, the more similar the materials to be learned, the more likely they will produce interference. For example, if you have to study two languages, you should study them on different days.

55. How do ‘grouping and rhythm’ facilitate learning? Give an example.

Answer: Grouping and rhythm help and facilitate learning and remembering. For example, a telephone number is learnt well when digits are grouped. The number 567345234 can be easily memorised and recalled if we try to group it as 567,345,234. Similarly, rhythm also proves to be an aid in learning; for instance, children effectively learn multiplication tables in a sing-song fashion.

56. How do internal factors within a learner affect memory?

Answer: Internal factors such as a learner’s physical and mental health and state of mind at the time of learning and reproduction affect memory. A fresh mind is able to learn more and retain it for a longer time than a tired and dull one. Emotions also affect memory, so emotional tensions should be removed as far as possible. Regular sleep is also important as it helps in removing fatigue and monotony.

57. What is the difference between passive and active forgetting?

Answer: Passive or natural forgetting is the kind of forgetting in which there is no intention to forget on the part of an individual. One does not make any deliberate efforts, and with the lapse of time, one gradually forgets things experienced and learned earlier.

Active or morbid forgetting is when one deliberately tries to forget something. This kind of forgetfulness originates from repression, where painful experiences and bitter memories are deliberately pushed into the unconscious layer of the mind.

58. What is Motivated Forgetting?

Answer: Motivated forgetting is a kind of forgetting in which the individual intentionally forgets. The information stored can be retrieved, but the individual does not want those memories and will repress them. It is a psychological process whereby unpleasant or conflicting experiences are repressed and pushed into the unconscious because remembering them may cause anxiety.

59. What is the difference between psychological and biological amnesia?

Answer: Psychological amnesia takes place as a result of major disturbances in the process of encoding, storage, and retrieval.

Biological amnesia is caused by the abnormal functioning of the brain. This abnormality may be due to causes such as a blow on the head, temporary disturbances in blood supply to the brain, certain drugs, or brain diseases.

60. Explain the Trace Decay Theory of forgetting.

Answer: The Trace Decay Theory states that memory traces, also called engrams, are responsible for our memory and are formed in our neurological systems. According to this view, forgetting is a process of the fading of learnt matter with the passage of time. If the learnt processes are not used for a long time, the traces get faded. This fading or decay could be the result of the normal metabolic processes of the brain, which might cause the traces to disintegrate gradually and eventually disappear.

61. Explain the Repression Theory of forgetting.

Answer: The Repression Theory states that repression is a defensive mechanism. As explained by Freud in his theory of psychoanalysis, painful experiences and forbidden wishes are pushed into an unconscious state, and the individual does not want to remember them. Although they may try to come to the conscious level, they are pushed back or avoided consciously. This is a purposeful or motivated forgetting, where we forget memories that we do not want to remember.

62. What is childhood amnesia? What are its possible causes?

Answer: Childhood amnesia is the inability to retrieve childhood memories. One possible cause is that these memories are unpleasant and may cause feelings of guilt, hence they are repressed. Another reason may be due to differences in the ways of encoding. During childhood, experiences are encoded and stored in a non-verbal form, but as a child develops and learns language, information is stored in the verbal form. This difference leads to retrieval problems, making the child unable to recall childhood memories.

63. What is defensive amnesia? What are its characteristics?

Answer: Defensive amnesia is developed to defend self-respect and to overcome anxiety. A person suffering from this type of amnesia may forget his name, occupation, and names of relatives, but not basic habits like eating, drinking, and talking. This generally takes place when an individual is in a very critical situation that may cause damage to his self-respect. At times, a person in this condition may escape by running away to distant places, which is called fugue. This amnesia may last for weeks, months, or years.

64. Explain the first factor of memory, ‘Registration or Learning’, in detail.

Answer: Registration or Learning is the first factor in the process of memory. Learning is the acquisition of new information from experiences, which leads to the establishment of an association of ideas in the mind. This factor is the way to register the first impression of an object or idea, without which memorisation cannot take place. Before something can be remembered, it must be registered or learned. Learning requires time and has an economical use of time.

The most efficient methods of learning or memorising for effective long-term remembering are:

Rote Memorisation: This is learning without understanding. Meaningful material is easier to learn than nonsense material. For example, poetry is easier to learn than prose, and prose is easier than disconnected words. A logical sequence and systematic arrangement of ideas are important.
Spaced v/s Mass Learning: Spaced learning allows for rest during memorisation, following the principle of ‘work and rest’. Mass learning involves memorising material in one sitting without rest.
Whole v/s Part Method of Learning: In the whole method, material like a poem is read repeatedly from start to finish. In the part method, the material is broken into parts or stanzas, which are learned individually.
Recitation: This is a method where a student reads a lesson a few times and then reviews it without the book by reciting the material learned.
Mnemonic devices: These are artificial associations made to link ideas or material, helping to improve memory.

65. Compare and contrast Spaced learning with Mass learning.

Answer: In spaced learning, the learner is allowed some rest during memorisation. The subject is not required to memorise the assignment in one continuous time period, as intervals are provided. The principle of ‘work and rest’ is followed. In contrast, in mass learning, the subject has to memorise the assigned material at one sitting without any interval or rest until it is mastered.

Shorter study periods are better for young pupils and slow learners. Spaced learning benefits pupils of lower classes, especially when the motivation level is low or the material is complex and difficult to understand. Introducing periods of rest while studying helps in removing the monotony of long study periods, prevents attention from flagging, and avoids fatigue. Mass learning is effective when the pupils are very intelligent or are highly motivated. Both methods can be useful and effective in different situations, and success depends more on the individual’s abilities and the nature of the material than on the method itself.

66. Compare and contrast the ‘Whole method’ and ‘Part method’ of learning.

Answer: The ‘Whole method’ of learning involves reading material, such as a poem, again and again from start to finish. This method is suitable when the material is not very lengthy and is logically arranged. It generally uses less time compared to the part method.

In the ‘Part method’ of learning, the material is broken down into parts or stanzas, which are then learned individually. This method benefits slow learners and average students. The learner is motivated each time they master a part, and the whole content is slowly mastered. The part method can be used even when the material is large and not well organised.

67. Explain the process of retention and the concept of the ‘Memory Trace’.

Answer: The process of learning involves the stage of retention, which makes learning permanent. Retention is the inactive state of a learned activity. A learning activity leaves a mark on the brain structure, and this mark is called a ‘Memory Trace,’ which is imprinted on the Cerebral Cortex. The preservation of this memory trace in the brain constitutes the retaining of the learning activity.

This can be compared to footprints made on the sand. The deeper the trace, the longer the retention, while weak traces slowly fade away. While memory can be improved, the depth of the trace or retention is difficult to improve by practice because the traces that are made depend on genetic inheritance.

68. Explain the three ways in which retention can be measured: recall, recognition, and relearning.

Answer: Retention can be measured in three ways: recall, recognition, and relearning.

Recall is a direct method of testing retention where the capacity to recall and reproduce is tested. We can recall matter only if we have retained it, for example, when writing a test. However, sometimes we are unable to recall even when we know the matter, so it is considered the poorest retention score of all that is learned.

Recognition is a widely used method where a response is given from which the pupil has to pick out or recognise the correct answer. This ability to recognise the correct answer helps measure the power of retention. It has a higher score of testing retention than the recall method and puts less strain on the child, as seen in multiple-choice questions.

Relearning is a method where, even if we cannot recall or recognise learned material, we can pick it up, understand, and master it very soon if we learn it again. A student who has learned lessons perfectly may be unable to recall them months later, but upon relearning, they can grasp and reproduce everything with ease and in much less time than the first time. This reduction in time and trials indicates that retention has taken place.

69. Describe the three stages of memory: Sensory, Short-Term, and Long-Term Memory.

Answer: Memory is not a single system; it has more than one distinct system. According to the most acceptable model, there are three major systems or stages of memory: Sensory Memory, Short-Term Memory (STM), and Long-Term Memory (LTM).

Sensory Memory holds representations of sensory input for very brief periods. For instance, a clear visual image of an object will last in sensory memory for about half a second after the stimulus is removed. There are different sensory registers for each of the senses.

Short-Term Memory (STM) holds relatively small amounts of information for brief periods, usually 30 seconds or less. This is the memory system we use when we look up a phone number and dial it. Short-term storage is not just a passive “holding area” but involves active processing of information, which is why it is also called “working memory.”

Long-Term Memory (LTM) is the memory system for the retention of large amounts of information for longer periods. It is the system that permits us to remember events that happened many years ago, yesterday, or last year. LTM allows us to remember factual information, making it possible to learn different subjects, appear for examinations, and communicate with others, bringing continuity and meaning to our life.

70. How does information move from Sensory Memory to Long-Term Memory? Explain the role of attention and rehearsal.

Answer: Information moves successively through the three memory systems—Sensory Memory, Short-Term Memory (STM), and Long-Term Memory (LTM)—if attention is given to the material. If attention, or focused awareness, is not given, the information does not move further into the system.

Information in the sensory memory enters short-term memory when it becomes the focus of our attention. If we do not pay attention to the incoming sensory information, the material fades and quickly disappears. This is known as “selective attention.” The information from STM is then often rehearsed. This rehearsal helps the transfer of that information from STM to LTM. When we pay attention to a piece of information and engage in active rehearsal, the material is stored in the long-term memory (LTM).

71. Explain any four techniques that can be used to improve one’s memory.

Answer: Four techniques that can be used to improve memory are:

Deep Processing: If you want to learn something and enter it into long-term memory, you have to think about it. You need to consider its meaning and examine its relationship to information you already have. The retention of material depends directly on the depth at which it has been processed. Deeper processing also refers to the rehearsal of material, and greater rehearsal increases the chances of recalling it later.
Distributed practice: It is beneficial to learn material using distributed practice, where there is a gap between trials. One should take rest after a period of study. If a chapter is lengthy, it should be divided into two or three parts, learning one part at a time before moving to the next. One should not try to cram all the information at once.
Using memory aids: People use various cues, indicators, and signs to connect events, which facilitates remembering. You can use visual imagery to remember objects and places. For example, to remember the location of a new place, you can remember it by associating it with a nearby cinema hall or a signal post.
Shorthand codes: You can develop your own shorthand codes to memorise long lists of items by using the first letter of each word to construct a unique “word”. For example, to remember the seven constituents of light, we use VIBGYOR. During school days, the shorthand code “BHAJSA” was used to remember the order of Mughal emperors: B for Babar, H for Humayun, A for Akbar, J for Jahangir, S for Shahjahan, and A for Aurangzeb.

72. Explain the SQ4R technique for effective learning and memorisation.

Answer: The SQ4R technique was developed by Thomas Robinson for effective learning and memorisation. The steps are:

Survey: Initially, the material to be remembered is surveyed quickly to get an idea of what is going to be remembered.
Question: In this step, the learner asks himself/herself questions like why, what, when, where, and who concerning the material surveyed in the first step.
Read: The material is then read for mental comprehension and to learn the answer to the questions raised in the second step.
Reflect: The information given in the required material is organised and made meaningful by linking it with previous knowledge, comparing and contrasting the facts, correlating the information with other similar facts, concepts, and principles, and attempting to make use of the material in solving simulated problems.
Recite and Recall: The information provided in the material is remembered through recitation and recall, both orally and in writing.
Review: In the final stage, the material needs to be actively reviewed.

73. Explain the Theory of Interference as a factor influencing forgetting, including its two types.

Answer: The Theory of Interference suggests that forgetting is not caused just by the fading away of memory traces, but by the influence of intervening activities. This theory has two types of interference:

Retroactive interference: In this type, new learning works backwards and interferes with old learning. The learning of new material makes it difficult to recall previously learned information.
Proactive Inhibition or Interference: In this type, what we have learned previously interferes with new learning. Our ability to recall what we have learned is reduced by experiences that were previously learned. Forgetting in our daily life is more often due to proactive interference.

74. What is amnesia? Explain the different kinds of psychological amnesia.

Answer: The term “amnesia” refers to a loss of memory. It is a kind of memory disorder that occurs from a loss of what has already been stored. One type of amnesia is psychological amnesia, which takes place as a result of major disturbances in the process of encoding, storage, and retrieval.

The different kinds of psychological amnesia are:

Childhood amnesia: This may be caused by the inability to retrieve unpleasant childhood memories, which may be repressed due to feelings of guilt. Another reason may be the differences in encoding; during childhood, experiences are encoded in a non-verbal form, but as a child learns language, information is stored in a verbal form, leading to retrieval problems.
Dream amnesia: Every individual experiences dreams but is often unable to recall their contents because many dreams are in a disguised form, so there are no cues to bring them to memory.
Defensive amnesia: This is developed to defend self-respect and overcome anxiety. A person with this amnesia may forget their name, occupation, and relatives, but not basic habits like eating or drinking. It often occurs in critical situations that may damage self-respect. Sometimes, a person may run away to a distant place, a condition called fugue. This amnesia can last for weeks, months, or years.

75. What is biological amnesia? What are its causes and different types?

Answer: Biological amnesia is caused by the abnormal functioning of the brain. This abnormality may be due to causes such as a blow on the head, temporary disturbances in blood supply to the brain, certain drugs like marijuana and alcohol, brain diseases, and other damages to the brain. These problems can result in transient global amnesia, which is a profound memory loss where all stored information is lost and no new memories can be formed.

There are two types of such amnesia:

Anterograde amnesia: This is the inability to store new information from after the incident.
Retrograde amnesia: This involves the forgetting of past memories from before the incident.

Other conditions like chronic alcoholism can cause brain damage leading to Korsakoff syndrome, where memory loss is predominant. Arteriosclerosis, Senile dementia due to age, and Alzheimer’s disease also result in amnesia.

76. Discuss the main theories that explain why we forget.

Answer: There are several theories that explain why forgetting occurs. The main theories are:

The Trace Decay Theory: This theory suggests that memory traces, also called engrams, are responsible for our memory and are formed in our neurological systems. If these learned processes are not used for a long time, the traces get faded. According to this theory, the lapse of time is responsible for forgetting.
Theory of Inhibition or Interference: This theory states that for material to remain in memory, it must form memory traces in the brain. As we learn and experience more, more memory traces are formed, and some overlapping of these traces can occur, resulting in obliteration and interference. Here, one learning will interfere with or inhibit the memory process of another. There are two types: retroactive inhibition, where new learning interferes with old memories, and proactive inhibition, where previous learning interferes with new learning.
The Repression Theory: This theory views repression as a defensive mechanism. As explained by Freud, painful experiences and forbidden wishes are pushed into an unconscious state because the individual does not want to remember them. Although they may try to come to the conscious level, they are pushed back or avoided consciously. This is a purposeful or motivated forgetting of memories we do not want to remember, such as the name of a teacher who severely punished a student.

77. What are the four factors of memory? Explain each factor in detail with relevant examples.

Answer: Memory is a mental ability in which different types of processes are involved. There are four different factors or processes in memory: Registration or Learning, Retention, Recall, and Recognition.

Registration or Learning is the first factor in the process of memory. It is the acquisition of new information or experiences which leads to the establishment of the association of ideas in the mind. This factor is the way to register the first impression of an object or idea, without which memorisation cannot take place. Before remembering, something must be registered or learnt.

Retention is the second factor. The process of learning involves the stage of retention, thus learning becomes permanent. Retention is the inactive state of learnt activity. The learning activity leaves a mark on the brain structure called a ‘Memory Trace’, which is imprinted on the Cerebral Cortex. This preservation of the memory trace in the brain is the retaining of the learning activity. This can be compared to footprints made on the sand; the deeper the trace, the longer the retention, while weak traces slowly fade away. Retention can be measured through recall, recognition, and relearning.

Recall is the third factor of memory. It means the presentation of any past experience in the form of an image or language in the conscious level of the mind. It involves the association of ideas. For example, upon seeing a car on the roadside, a person may remember the name of its owner because the car owner is known to the person. Recall depends on the mental condition and the memory trace formed.

Recognition is the fourth factor of memory. It is the capacity to be aware of a previous experience. If a person can identify an ‘object or idea’ at present of which he or she has a past experience, it is called ‘recognition’. It means familiarity with something and the ability to judge whether something is identical with a perceived experience on an earlier occasion. For example, when we meet a person, we may recognise that person’s face but may not be able to recall his name. It is easier to recognise than to recall.

78. Discuss the various efficient methods of learning or memorising that can lead to better retention.

Answer: The most efficient methods of learning or memorising that would yield the best results for remembering effectively for a long time are as follows:

Rote Memorisation: This is learning without understanding. Yet meaningful material is more easily learnt than nonsense material. It is easier to learn poetry than prose, and prose is easier to learn than disconnected words. Thus, a logical sequence is important, along with the systematic arrangement of ideas. However, mechanical learning must be avoided as it is less effective.
Spaced v/s Mass Learning: In spaced learning, the learner is allowed some rest during memorisation, following the principle of ‘work and rest’. The subject is not required to memorise the assignment in one continuous time period. In mass learning, the subject has to memorise the material at one sitting without any interval. Spaced learning is better for young pupils, slow learners, or when the material is complex, as it helps remove monotony and avoid fatigue. Mass learning is effective when pupils are very intelligent or highly motivated.
Whole v/s Part Method of Learning: In the whole method, a poem, for example, is read again and again from start to finish. This method is suitable when the material is not very lengthy and is logically arranged. In the part method, the poem is broken down into parts or stanzas and then learnt. This benefits slow learners and average students, as the learner is motivated each time they master a part. This method can be used even when the material is large and not well organised.
Recitation: This is the best method of learning, where the student reads the lesson a few times and then reviews it without the book by reciting the material learnt. Self-recitation is better and more time-saving than just reading and rereading because it helps achieve permanent retention. The learner can detect and rectify their weaknesses and know their progress.
Mnemonic devices: Grouping helps in memorising easily. When material does not have natural grouping, artificial associations are made to associate the ideas. Memory which is improved by the use of artificial associates is called Mnemonics. This allows things to be learnt verbatim without understanding them.

79. Explain the different types of memory (Immediate, Short-term, Long-term) with suitable examples for each.

Answer: Individuals differ in their power of memorisation and are said to possess different types of memory. Some important types are:

Immediate Memory: This is also known as short term memory. This memory is used when the individual has to reproduce something immediately after learning it, so the time span is very less for the matter to be registered in the consciousness. The learnt matter is forgotten rapidly. For example, we may first look at the seat number of our ticket, and once we sit down, we forget about it. In this type of memory, the retention time is very brief.
Short-term memory: This type of memory is also called temporary memory and is not as short-lived as immediate memory. The information temporarily stored in short-term memory may last as long as thirty seconds even if the material is not being rehearsed. Some people can retain more information in short-term memories by a process called chunking, which groups information by coding it. For example, the number 143254376 can be remembered better by listing it under three heads: 143, 254, 376.
Long-term memory: This is also known as permanent memory. Here, the individual learns and retains information for a very long period of time. There is an interval between learning and recall or reproduction. Thus, permanent memory is involved in activities like knowing our bank account number or a phone number that we have retained for a long time.

80. What are the signs of a good memory? Discuss in detail the various tips and techniques to improve memory.

Answer: A person who can remember more of a learnt material than others is said to have a good memory. Good memory has certain characteristics, which are its signs. They are:

When a person can easily and rapidly learn a material, it definitely shows a good memory as he is relating it to a material learnt earlier.
An individual with good memory means that he can retain the maximum amount of learnt material in his/her mind.
Another sign of good memory is easy recall. The capacity to bring forth the image or language for use in the present situation, or easy reproduction of a learnt material to achieve a purpose, is a mark of good memory.
Clear and quick recognition is a sure sign of good memory.
Utility or serviceability is a sign of good memory. Remembering past situations and also trying to forget irrelevant things point towards good memory.

Almost anyone can improve their memory with little effort. Here are some tips and techniques to enhance memory:

Intention to Learn: A firm determination or strong will to learn is required. Retention is greater in students who have a determination to learn compared to those who are unwilling. Materials read, heard, or seen without intention are difficult to remember later.
Deep Processing: To enter information into long-term memory, you have to think about it, consider its meaning, and relate it to existing knowledge. The retention of material depends on the depth at which it has been processed and rehearsed.
Interest and attention: To learn something well, you have to put in a conscious effort to attend to it carefully. A person with no interest will not give due attention and will not be able to learn. As the saying goes, “Interest is the mother of attention and attention is the mother of memory”.
Minimise interference: Interference is a major cause of forgetting. The more similar the materials to be learned, the more likely they will interfere. You should arrange your studies so that you don’t study similar subjects one right after the other.
Distributed practice: It is beneficial to learn material using distributed practice, with a gap between trials. Take rest after a period of study. If a chapter is lengthy, divide it into parts and learn one part at a time.
Using memory aids: People use cues, indicators, and signs to connect events. You can use visual imagery to remember objects and places. For example, you may remember a new location by associating it with a nearby cinema hall or a signal post.
Shorthand codes: You can develop your own shorthand codes to memorise long lists. For example, to remember the seven constituents of light, we use VIBGYOR. To remember the order of Mughal emperors, we developed the shorthand code “BHAJSA” where B is for Babar, H for Humayun, and so on.
Meaningfulness: If the subject matter is meaningful and presented in an organised manner, it will be retained for a longer period.
Grouping and rhythm: These help in learning and remembering. For example, a telephone number is learnt well when digits are grouped, like 567,345,234. Children learn multiplication tables effectively in a sing-song fashion.
Repetition and recitation: Repetition and continuous practice add to the effectiveness of memorisation. Intelligent repetition with full understanding helps in making learning effective and enduring.
Internal factors within the learner: The learner’s physical and mental health and state of mind at the time of learning affect memory. Due attention should be given to improving the student’s health. Emotions should be trained, and regular sleep helps in removing fatigue.
Making use of SQ4R Techniques: This strategy for effective learning involves:
- Survey: Quickly survey the material to get an idea of what is to be remembered.
- Question: Ask questions like why, what, when, where, and who concerning the material.
- Read: Read the material for mental comprehension and to answer the questions.
- Reflect: Organise the information by linking it with previous knowledge and comparing facts.
- Recite and Recall: Remember the information through oral and written recitation and recall.
- Review: Actively review the material in the final stage.

81. What is forgetting? Discuss the various factors that influence forgetting.

Answer: Forgetting is very common to us all and is the opposite of remembering. It is the inability to recall previously learnt material. Forgetting occurs only when some learning has taken place; if there is no learning, there is no forgetting. Thus, forgetting and remembering are two sides of the same coin. According to Aristotle, forgetting is the fading of an original experience with the passage of time, arising from disuse. Munn defines it as the loss, permanent or temporary, of the ability to recall or recognise something learned earlier. In this way, forgetting is the opposite of remembering and is essentially a failure in the ability to reproduce.

The factors that influence forgetting are:

Theory of Decay: This view suggests that forgetting is a process of the fading of learnt matter with the passage of time. The vivid impressions created in the cerebral cortex fade away as time passes, possibly due to normal metabolic processes of the brain that cause the memory traces to disintegrate.
Interference of Association or Theory of Interference: This theory states that forgetting is caused not by the fading of traces but by the influence of intervening activities.
- Retroactive interferences: Here, new learning works backwards and interferes with old learning.
- Proactive Inhibition or Interference: Here, what we have learnt previously interferes with new learning. Our ability to recall what we have learnt is reduced by experiences previously learnt.
Theory of Repression or Motivated Forgetting: This is a psychological process where unpleasant or conflicting experiences are repressed and pushed into the unconscious and forgotten. This is done because remembering the experiences may cause anxiety. For example, we may want to forget people who have hurt us or loved ones whom we will never see again.
Emotions: A rise in emotions like fear, anger, or love can lead to forgetting learned experiences. For example, a student who is afraid of a teacher may forget what has been learnt.
Change of Stimulus Conditions: We may have learnt something in a specific environment but forget it in a changed environment. For example, we can deliver a speech well at home but are unable to speak in front of an audience.
Poor Health: This prevents us from remembering learnt material.

82. Discuss the different kinds of forgetting and their causes, including interference and retrieval problems.

Answer: There are two kinds of forgetting:

Passive or Natural Forgetting: This is the kind of forgetting in which there is no intention to forget on the part of an individual. One does not make any deliberate efforts. In a quite normal way, with the lapse of time, one gradually forgets many things experienced and learned earlier.
Active or Morbid Forgetting: This is also known as abnormal forgetting. In this type, one deliberately tries to forget something. This kind of forgetfulness, as explained by Freud, originates from repression. Under this process, painful experiences and bitter memories are deliberately pushed into the unconscious layer of the mind.

The causes of forgetting are:

Faulty Memory Process: Sometimes we listen to many details but encode only a portion of the information as a gist, not the actual words. This distorted information is what gets stored. We then remember the distortions, which is not an accurate representation of what happened, making us think we have forgotten.
Interference: An important cause of forgetting is the interference of learnt material. There are two kinds:
- Proactive inhibition: This occurs when earlier learning interferes with later learning and inhibits the recall of new material. For example, when trying to remember the names of people met at a party yesterday, we might recall the names of people we met last week instead.
- Retroactive inhibition: This is the inhibition of earlier learning and recall by later learning. For example, a student who learnt about motivation last week and perception this week may find that points about perception come to mind when trying to recall information about motivation.
Retrieval Problems: Retrieval is necessary for recall. Without appropriate retrieval cues or remainders to direct the memory search to the correct part of the Long-Term Memory (LTM), the sought-for items stored in LTM may not be found, which leads to forgetting.
Motivated Forgetting: This is a kind of forgetting in which the individual intentionally forgets. The information is stored and can be retrieved, but the individual does not want those memories and represses them. People generally remember pleasant experiences more than unpleasant ones.
Amnesia: This refers to a loss of memory. It is a memory disorder that occurs from a loss of what has already been stored. It can be psychological, caused by disturbances in encoding, storage, and retrieval, or biological, caused by abnormal brain functioning due to a head injury, drugs, or brain diseases.

83. Describe the complete model of memory, from sensory input to long-term storage, explaining the function of each stage.

Answer: Memory is not a single system but has more than one distinct system. According to the most acceptable model, there are three major systems of memory: Sensory Memory, Short-Term Memory (STM), and Long-Term Memory (LTM). Information moves successively through these three systems if attention is given to the material. If attention is not given, the information does not move further into the system.

The first stage is Sensory Memory. It holds representations of sensory input for very brief periods, depending on the sense involved. For example, a clear visual image of an object will last in sensory memory for about half a second after the stimulus is removed. If we do not pay attention to the incoming sensory information, the material fades and quickly disappears.

The second stage is Short-Term Memory (STM). When information in the sensory memory becomes the focus of our attention, it enters short-term memory. STM holds relatively small amounts of information for brief periods, usually 30 seconds or less. This is the memory system we use when we look up a phone number and dial it. If we are connected on the first try, the number is forgotten. STM is not just a passive holding area but involves active processing of information, which is why it is also called “working memory”.

The third stage is Long-Term Memory (LTM). Information from STM is often rehearsed, and this rehearsal helps transfer the information to LTM. LTM is the memory system for the retention of large amounts of information for longer periods. It is the system that permits us to remember events that happened many years ago, as well as factual information for learning subjects and appearing for examinations. It brings continuity and meaning to our life.

84. Discuss in detail the processes and factors involved in memory.

Answer: Memory is the special ability of our mind to store what we learn to recollect and reproduce it after some time. It is crucial in our life because it helps build bridges in the flow of experiences and allows us to have a sense of continuity. Several experts have defined memory.

Stout: “Memory is the ideal revival so far as ideal revival is merely reproductive. This productive aspect of ideal revival requires the object of past experiences to be re-instated as far as possible in the order and manner of their original occurrence”.
James Drever: “Memory is that characteristic which underlines all learning, the essential feature of which is reflection. In a narrow sense it is recall and recognition”.
Woodworth and Marquis: “Memory is mental power which consists of learning, retaining, and remembering what has previously been learnt”.
Ryburn: “The power that we have to store our experiences, and to bring them into the field of our consciousness sometimes after the experiences have occurred, it is termed as memory”.
Guilford: “Memory is the retention or storage of information in any form”.
F’iedsetal: “Memory is the ability to retain and reproduce impressions once perceived”.

Memory is a mental ability in which different types of processes are involved. There are four different factors or processes in memory:

Registration or Learning: This is the first factor of the process of memory. Learning is the acquisition of new information or experiences which leads to the establishment of the association of ideas in mind. This factor is the way to register the first impression of an object or idea, without which memorisation cannot take place.
Retention: The process of learning involves the stage of retention, thus learning becomes permanent. Retention is the inactive state of learnt activity. The learning activity leaves a mark on the brain structure, called a ‘Memory Trace’, which is imprinted on the Cerebral Cortex. This preservation of the memory trace is the retaining of the learning activity. The deeper the trace, the longer the retention. Retention can be measured through recall, recognition, and relearning.
Recall: The third factor of memory is recall. It means the presentation of any past experience in the form of an image or language in the conscious level of the mind. It involves the association of ideas. Recall depends on the mental condition and the memory trace formed.
Recognition: Recognition is the fourth factor of memory. It is the capacity to be aware of a previous experience. If a person can identify an ‘object or idea’ at present of which he or she has a past experience, it is called ‘recognition’. It is easier to recognise than to recall.

There are different types of memory that individuals possess. Some important types are:

Immediate Memory: This is also known as short-term memory. This memory is when the individual has to reproduce immediately after learning something. The time span is very less for the matter to be registered in the consciousness, and the learnt matter is forgotten rapidly. The retention time is very brief.
Short-term memory: This type of memory is also called temporary memory. It is not as short-lived as immediate memory. The information temporarily stored may last as long as thirty seconds even if the material is not being rehearsed. Some people can retain more information through a process called chunking, which groups information by coding it.
Long-term memory: This is also known as permanent memory. Here the individual learns and retains the information for a very long period of time. There is an interval of time between learning and recall or reproduction.

Memory is not a single or unitary system; it has more than one distinct system. According to the most acceptable model, there are three major systems or stages of memory: Sensory Memory, Short-Term Memory (STM), and Long-Term Memory (LTM).

Sensory Memory: This stage holds representations of sensory input for very brief periods, depending on the modality involved. A clear visual image of any object will last in sensory memory for about half a second after the stimulus is removed.
Short-Term Memory (STM): This is the first stage where information moves if attention is given. It holds relatively small amounts of information for brief periods, usually 30 seconds or less. This system is also called “working memory” as it involves active processing of information, not just passive holding.
Long-Term Memory (LTM): This is the second stage. It refers to the memory system for the retention of large amounts of information for longer periods. It permits us to remember events that happened many years ago and allows us to remember factual information.

Information moves successively through these three systems if attention is given to the material. If attention is not given, information does not move further into the system.
