Memory and its types and Causes of Forgetting

Memory

Introduction
            Memory and forgetting are common phenomenon experienced by everybody. Life would have been happier if we would remember the most of what we learn. Learning itself is not enough but important thing is whether we remember or not. Memory has a great role to play in our learning and knowledge acquisition. Therefore it is important it is imperative for a teacher to know the dynamics of memory and forgetting so that he may understand the students better and help them by enhancing their memory resulting in better performance.

Definitions:
James Drever(1952)- “Memory is that characteristic which underlines all learning, the essential feature of which is reflection. In narrow sense it is recall and recognition.”
Woodworth and Marquis(1965)-  “Memory is mental power which consists in learning, retaining and remembering what has previously been learnt.”
Ryburn (1956)“The power that we have to store our experiences, and to bring them into the field of our consciousness some time after the experiences have occurred, it is termed as memory.”
            So memory is the capacity to retain the learnt material for a longer period of time and reproduce it through recognition or recall when it required.

How do we remember?

Atkinson and Schifrin developed the theory of storage and transfer model in which they explain how we remember. The process of memorization begins with the interaction of one’s sense organ with ones environment. Then it goes to sensory storage and pause for a second. There seems to be a sensory storage for each sense visual, auditory, smell, taste and touch. However visual and auditory storages system referred to as Iconic storage and Echoic storage. Other sense organs have also storage named as Heptic. The sensory information passing through sensory stores either disappears within a second or pass to short term store. Here information stays for about 20 seconds. In case short term store is able to hold information up to  up to 20 minutes then
It may go to the long term store. For transferring information from short term to long term one can use many control process. Rehearsal is one such activity and coding and other mental activities may aid long term memory. The stored as well as organized information in the long term store in the coded form is transferred back to the short term store where it is decoded and employed for responses as desired and ordered by the brain.
Components of Memory
            Memory involves four basic components or factors:
(1)Learning  (2) Retention or storage (3) Recall or retrieval  (4) recognition. These are all very closely related.
(1)Learning
            Chronologically learning precedes memory. It is the process of registering the impressions or acquiring new knowledge, skills, and attitudes and so on. The teacher has to be concerned about learning process to use very profitably various principles of remembering established by numerous experiments.
Meaningful learning:  Memorization is often done by the method of repetition. Repetition is absolutely necessary in the process of remembering. Children learn some words and rhymes without paying any attention to the meaning and significance of the material that has to be remembered. Hence attempt to be made to find out relationship among the different parts of the material itself. In other words the whole material is to be converted into a meaningful pattern with its various parts that fit together in a meaningful manner. Attempt should be made to relate the meaning and significance of the material with other things that we have learnt previously.
Sapaced and Unspaced learning: When trials are given without space or any break this space is called unspaced practice. Results indicate that there is a definite advantage in favour of spaced learning over unspaced learning method. Continuous study over a long period of time is not suitable to memorize the material.
Whole Vs Part Method of learning:  Experiments validate these two methods under different conditions. Meaning and organization favour whole method. Parts make a good sense in a whole than isolated. It also depends on the length of difficulty level of the material and also on the nature of learner, according to which part method is always superior for the children.
Part Progressive Method: In this method learning material is divided into different parts. First part is to be learnt then second and then first and second together then third then first second and third parts together and so on. It has some drawbacks also. Certain units get undue repetition whereas later units get fewer repetitions.
Mixed or Mediating Method: Difficult portions are selected in this method and the subject masters the difficulty first and then starts learning the material from the beginning through whole method till the second difficulty is reached. Again that difficulty is mastered and then material is learnt from the very beginning.
Repetition and recitation: From the view of performance of retention it has been found by experiments that the more we repeat, the better it is. Even after mastery over assignment it is advantageous to repeat the lesson a few more times in view of better retention.
Verbalization:  In the complex motor task, learning is facilitated by verbalization because it shows that motor skill is actually learnt as a pattern with both verbal and motor constituents. So learning proceeds much faster. So here learner should stress correct performance from the very beginning, space, accuracy and speed should be maintained.

(2)Retention
            This is ability to store information and remember. The process of retaining appears to be passive but is not wholly so. A good amount of mental activity goes on in connection with the process of retention. The ability to retain seems largely determined by genetic constitution. The decline of retention in old age is due to decline of the functioning of the brain.
Curve of Retention
(3)Recall
            We learn in order to recall  when we need. Failure to recall learned material would mean that our learning process has not been useful and effective. Recall is more difficult than learning. Recall is greatly affected by emotions and motivation both at the time of learning and subsequently.
(4)Recognition
            Parallel to recall, recognition is another factor in the process of memory. Recognition is awareness of previous experience it is complete familiarity without any mistake. Recognition is rather a type of experience than a sort of behavior. Recognition is simpler and more reliable too. For good retention recall and recognition go side by side. Recognition may appear to be passive behaviour. But in fact, recognition may also is an active process where perceptual process comes into play.

Measurement of retention Memory
            Psychologists have developed four methods to study the process of remembering.
1. Recall Method: In this method a person is required to reproduce what he had learnt in the past such as reproduction during examination. Here students are shown some words and after seeing them they are asked to reproduce as many as words possible.
2. Relearning Method:   Here subject is asked to relearn the already learnt material. The difference between the number of trials and time taken in two occasions of learning is considered to be the index of retention. This index is often referred to as saving score. It is because time and trials are saved in the second learning.
3. Recognition Method: Recognition means distinction between seen and unseen. When we take multiple choice questions in the examination we recognize the correct answer out of the choice given.
4. Reproduction: Here learner is asked to reproduce what he had learnt in the past exactly and correctly. The retention is measured on the basis of errors made by the learner in the reproduction. Lesser the number of mistakes higher will be the retaining power of the learner.

Types of Memory
            Depending on the nature of learning tasks and age, nature and capacity of learner, memory could be of different categories.
1. Short term Memory: Short term memory  does not  lasts for more than few seconds long situated in the prefrontal cortex. It lets the individual keep several things in mind at the same time. For instance, conversation enables one to remember the beginning of a sentence until speaker gets the end.
2. Long Term Memory: It represents our general knowledge about the working of the world, and is located in the angular gyrus. The memory of words, symbols, corporate trademarks are unforgettable.  Even though not used for years, they will not fade away. Habit memory is the function of the body and is related with motor mechanism. Once learnt how to ride bicycle, drive a car or swim, it is likely that those are not forgotten.
3. Remote Memory: It is the life time accumulation of data a wide variety of topics. It is spread around the cerebral cortex. It seems to diminish with age. The decline could be retrieval problem.
4. Rote memory: Result of rote learning by children they remember without understanding.
5. Episodic Memory: this is the memory of specific personal experiences.
6. Sensory Memory: Sensory impressions retain that knowledge.
·        Auditory Memory-- Memory of auditory impressions.
·        Visual Memory – Memory of visual impressions.
·        Tactual Memory – Memory of touch is rich in blind
·        Olfactory Memory--Memory of Smell
·        Gustatory Memory—Memory of Tastes


Memory Improvement techniques
             These are a few memory improvement techniques useful for the learners.
1. Will to learn: There must be strong determination or will to learn effectively and successfully.
2. Interest and Attention: Interest and attention are essential for useful learning and memorization. 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.
3. Over learning: If subject matter is properly learnt then the retention will be high.
4. Meaningfulness: If the subject matter taught to students is meaningful and it has been presented to them in an organinsed manner, it will be retained for longer period of time.
5. Following the Principle of association: A thing never should be learnt in an isolated manner. An effort should be made to connect it  with previous learning on the one hand and with as many related things possible on the other.
6. Grouping and rhythm: grouping and rhythm also help and facilitate learning and help in remembering. For example telephone no. is learnt better when digits are grouped. Children learn the multiplication table by rhythmic recitation.
7. Using as many sense as possible: Senses are said to be the gateways of knowledge and it has also been found that things are better learnt and remembered when they are presented through more than one senses.
8. Learner’s   internal factors: The attention should be given to the student’s physical and mental well being. His emotions should be trained and emotional tensions removed as far as possible.
9. Provisions for change and Proper rest: Adequate provision for rest, sleep and variety in the work should be made as this helps to relieve fatigue and monotony.
10. Repetition and recitation: Finally repetition and continuous practice add to the effectiveness of memorization. Intelligent repetition with full understanding always helps the making learning effective and enduring and things repeated and practiced frequently are remembered for a long time.
11. Making use of SQ4R Techniques: Thomas Robinson developed this strategy for effective learning and memorization.
·        Survey: Initially the material to be remembered is surveyed quickly and get an idea of what is going to be remembered.
·        Question: In this step the learner asks himself 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 organized  and made meaningful by linking it with the 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 needed to be actively reviewed.
12. Making use of mnemonics: This system makes use of the use of visual imagery to provide useful association and connections for remembering the required materials. Ex. Peg word method tells us how the counting is learnt with the help of rhythmic association of places like one is a gun; two is a shoe and so on. There are other methods also like key word method a word is remembered through a key word, initial letter strategy.



Forgetting
            Forgetting is much common to all. It is opposite of remembering. Much of what has been learnt is subjected to forgetting with the passage of time. For instance a poem you have learnt in your elementary school might have been forgotten at least partially. This is the inability to recall previously learnt materially is essential aspect of learning process.
Definitions:
Munn(1967)- “Forgetting is the loss, permanent or temporary, of the ability to recall or recognize something learned earlier.”
Drever(1952) -  “ Forgetting means failure  at any time to recall an experiences, when attempting to do so, or to perform an action previously learned.”
Cause of Forgetting
             There are  two kinds of forgetting 1. Normal forgetting  2. Abnormal forgetting
1)Normal forgetting is the result of different types of cause;
        i.            The trace decay theory: With the lapse of time what is learnt is forgotten. Older the   experience the weaker its memory. With the passage of time, through disuse, the memory of impressions of what we learn  gets weaker and finally fades away  ex. Mathematical formulae, however well learned if never used  or reviewed  might be forgotten.
      ii.            Interference: There is a possibility of overlapping of the learnt material. Forgetting by interference is a case of retention amnesia, as here it is the stability  and existence of memory traces that are disturbed. Experiments have shown definite evidence in favour of sleep or rest as a condition helping better retention. Crowded learning, unspaced learning does not yield good results.
    iii.            Retroactive and Proactive inhibitions: Inhibition means checking or causing to withhold. It has been found that if one period of learning ‘A’  is immediately followed by another effort at learning ‘B’ which is similar material, there is a great deal  of inhibition when any one has to be recalled. While recalling ‘A’ if ‘B’ material interferers it is retroactive inhibition. While recalling ‘B’ if ‘A’ material interferes it is proactive inhibition. If the materials are dissimilar, through learned one after another, inhibition is less.
   iv.            No meaning: If the learning is not meaningful forgetting occurs as it does not give scope for the development of relationships.
     v.            Inadequate impressions: Inadequate impressions at the time of learning leads to forgetting.Overlearned lessons are better retained.
   vi.            Lack of interest: Lack of interest in the learning material leads to forgetting.
 vii.            Mental and physical ill health: Mental and physical ill health sets in physical and mental fatigue and affects learning.
viii.            Motivated forgetting: Unpleasant events are to be forgotten soon to participate in the present.

2) Abnormal forgetting: Abnormal forgetting may result from external causes such as a severe injury to the brain due to accident or otherwise retention amnesia. Abnormal forgetting also may be due to repression of certain parts or details or certain experiences involving guilt, shame or frustration which are not palatable to the main stream of conscious mind.

Educational Implications
The teacher should design his methodology of teaching according to the theories of memory and forgetting. Following suggestions could be helpful in enhancing their memory.
¨ Awareness of the different memory levels of children.
¨ Knowing and understanding the student and helping him to  overcome the traumatic experiences and unwanted feelings
¨ Creation of conducive environment  and condition for learning
¨ Utilizing as many sense possible
¨ Occasional test of memory
¨ Use of memory enhancing techniques.

Conclusion
            Remembering is a process of developing association and sustaining the same by practice. There are memories pertaining to different sensory modalities. Memory has four part processes such as learning, retention, recall and recognition. Adaptation of sound method of learning such as recitation, distributed practice, studying as a whole would ensure good retention. Improvement of memory is possible by better organization of the material, developing interest in the subject and also removing distractions. Sometimes forgetting is blessing in disguise because one need not remember things that are no more needed.

Review Questions
1. What is the part process of learning?
2. Why is recitation preferred to repetition?
3. Why is distributed practice is better than massed practice?
4. Why does a person fail to recall?
5. What are the causes of forgetting?
6. What are short term and long term memory?
