Types of Memory + Procedural Memory + Declarative Memory

TYPES OF MEMORY
Memory and memories have been defined or classified in different ways. Established is that there are two main types of memory, namely 'procedural memory' with information about how to proceed when doing something, and 'declarative memory' which contains what we know.
Both procedural and declarative memories are long-term memories and we also have a working (short-term) memory which enables the brain to evaluate the mass of incoming information and select what is to be retained and memorised and what is to be rejected.
Distinctions have been drawn also between different kinds of memory and memories, such as semantic (verbal), episodic (events as part of a sequence), eidetic (detailed mental images) and visual (images as seen). In addition to what we see, we also remember other sensory information such as sounds, smells, tastes and what we touch.

Procedural Memory
This memory stores information about how to proceed when doing something, stores information such as how to drive a car, play football or play an instrument.
This type of memory is long-lasting. The memories are actions, habits or skills which are learned by repetition and which can be changed by many repetitions, by training. {11, 14}

Declarative Memory
This is long-term memory and it contains all you have experienced or learned, all the information gained by you from childhood onwards.
No one really knows where this enormous database is located but it seems that each type of component memory is located in a kind of memory location of its own.

Associating Memories and their Components
Suppose we remember a person saying something. The component parts of this memory, components such as shape of face, sound of voice, colour of hair, are stored in different locations. They are associated with each other, cross-indexed if you like, so that a memory can be recalled from remembering just one of its components. Component memories are continually being associated with other old or new component memories, enormously increasing the range and flexibility of what can be recalled.
And so we may be able to recall a person's name by remembering the colour of his hair, or the shape of his face.

Working Memory
The working memory enables the brain to evaluate the mass of incoming information and select what is to be retained and memorised and what is to be rejected.

External Memory
In addition we have the vast mass of externally prepared and stored information which is accumulating. It has accumulated ever since people told stories to their young who in turn retold them to later generations and ever since writing was invented and the printed word accumulated, followed by pictures, photographs, films and videos, television and computerised manipulation of text and images. All of which spread and proliferated together with corresponding search (recall, retrieval, associating and selecting) procedures.

STORED INFORMATION (PERCEIVED CONTENT)
Much of what we are storing includes semantic information, that is information which consists of words and is about words, information relating to what words mean and imply.
And images, that is scenes, including events and sequences of events, and their components.
Including what happened, when it happened and the sequence in which it happened. People with an eidetic (image-retaining) memory remember images, often clearly and in detail <1>. "Many, if not all, young children apparently do normally see and remember eidetically, but this capacity is lost to most as they grow up. What is in young children an apparently general capacity has become a remarkable rarity in adults." {6} The information one receives may be fact or fiction, right or wrong, intended to inform or to mislead, understood or misunderstood. Even so, what is stored is the perceived content of the received information.

LEARNING (MEMORISING) AND UNDERSTANDING
Rose defines an animal's learning by "learning is a response by an animal to a novel situation such that, when confronted subsequently with a comparable situation, the animal's behaviour is reliably modified in such a way as to make its response more appropriate" {6} <3>
Pointing out that human memory is very different from that of a non-human animal, Rose says that "procedural memory dominates the lives of non-human animals, ... but declarative memory profoundly shapes our every act and thought." Our memory includes a verbal memory which "means the possibility of learning and remembering without manifest behaviour."

But our memory consists of much more than just verbal memories.
Continually associating new information with older information, and older information with other older information, is much more than random cross-referencing.
It is because of the meaningful way in which we associate over such large volumes of stored information, that the process of associating amounts also to the seeking of meaningful associations. So to me it seems that all the information we take in and retain results in a more comprehensive view and deeper understanding of the world in which we live, of our social organisation and physical environment. Thus, in the end, at some time and in some way, the information we have taken in affects and changes what we do, changes our behaviour.

INSTINCTS AND INSTINCTIVE BEHAVIOUR
We saw that instincts are an innate form of behaviour, that is a form of behaviour which is not learned but which the animal performs from birth, without being trained to do so.
Behaviour relating to survival of a species, such as attack, defence and sexual behaviour, is instinctive and responses are automatic. Territory is acquired by force and defended. Might is right.

CONSCIOUS BEHAVIOUR: LEARNING AND EVALUATING, MEMORY AND MEMORISING

As mammals evolved from reptiles, there evolved the ability for storing new experiences as they happen and so creating a store of experience-based memories.

A primitive animal's memory seems to be largely procedural. Both procedural and declarative memories are long-term memories, but declarative memory is located and used in a different way.

Human beings are learning all the time, memorising information and then recalling it when it is required.
What is being memorised includes what we are taught, what happens to us and to others and any lessons learned as a result. And when it happened and the sequence in which it happened. Including also the meaning of words and what is implied. And in addition we have the vast mass of externally prepared and stored information which is accumulating at an accelerating pace.

Massive volumes of information are being received. The incoming information is evaluated and we memorise only information which seems to matter. Some is retained, the rest rejected. Retained short-term (working) memories are converted to long-term memories. So only a part of the incoming information is retained and stored, that is memorised, so becoming available for recalling later when required.
Aspects of memories <9> are stored in different locations. Aspects such as colour, shape, event, phrase, place, time, date. Aspects like shape of face, sound of voice, colour of hair.
Memories are associated, crossindexed if you like, with their different aspects and can be recalled by recalling an aspect associated with the memory one wishes to recall. Component memories are continually being associated with other old or new component memories, enormously increasing the range and flexibility of what can be recalled. A process which continually keeps available memory components which relate to those of current interest, and memory components which are more frequently used than others.


Human beings store memories by means of changed neural pathways, by means of persistent modifications to the structure of neurons and their synaptic connections, by means of biochemical changes. {6} <3>
So we are strengthening neural pathways or associations by frequently using or recalling them, weakening memory components which are not being used.
Hence using neural pathways holds memories at higher, more easily accessible levels of memory, makes them more readily available. Infrequently recalled memories would seem to be overlaid by more frequently used ones, seem to be reduced to lower levels of awareness, of accessibility.

ICOMMUNICATING NON-VERBALLY: CONVEYING INFORMATION BY USING IMAGES

Instinctive Behaviour
Subconscious Behaviour (Functioning)
Memorising

Instinctive Behaviour
Dreaming trains animals and human beings in instinctive responses and then keeps instinctive behaviour fully trained.
Dreaming does so by generating situations which require responses of the fight, flight, affection kind. A dream produces a corresponding response which, however, is not translated into action as the dreamer's body is normally paralysed by the mind for duration of dreaming (REM) sleep.
Frequent replaying strengthens corresponding neural pathways and so trains the individual to respond and to respond quickly.

Subconscious Behaviour (Functioning)
As mammals evolved from reptiles, the added functions included organs such as the autonomic nervous system for the automatic control of body functions, of functions such as digestion, the fluid balance, body temperature and blood pressure.
A key finding of this report is that the right hemisphere of the human brain is able to communicate by using images with the brain's older and more primitive component organs which have no verbal skills. And this enables us to communicate intentionally (that is 'consciously') with our autonomic nervous system and ask it by visualising to control body functions and to affect our body's immune system. Any or all our senses can be included when visualising.
Clinical trials have shown remarkable success in areas such as the treatment of cancer and heart disease. Communicating with one's autonomic nervous system by visualising is a conscious activity.
Hence it is possible to direct and use the mind's subconscious maintenance and control capabilities, and so enable environmental experience and knowledge to be applied for one's benefit. That is, one's knowledge and experience can be consciously applied towards modifying the mind's subconscious control of body functions for the benefit of the individual.

Memorising
It is while REM sleeping that dreams are generated and that we appear to be filing away (memorising) memories for later use. Much of dreaming may then be the creating and recalling of associations. As the night progresses this process seems to become more intuitive, delving deeper into stored memories and associations, associating with earlier memories and their aspects, tending to go back in time towards childhood.
Becoming more intuitive by going through likely or apparently associated filed images or other stored memory components (aspects) in their different locations.
In this way keeping long-term memories intact and relevant by continually associating and reassociating their various parts. So we are strengthening neural pathways or associations by frequently using or recalling them.
This process at the same time would seem to weaken those memory components we are not thinking about or which are not being used.


ADAPTING TO THE ENVIRONMENT: CHANGING INSTINCTIVE BEHAVIOUR


A key feature which distinguishes mammals from the reptiles from which they evolved would seem to be that the mammalian brain contains organs for the experience-based recognition of danger and for responding to this according to past experience. And for some conscious feelings about events.
Millions of neural pathways connect the organs which generate experience-based memories, and also those which generate conscious feelings with associated behavioural response patterns, to the reptilian parts of the mammalian brain.
It seems that feelings such as attachment, anger and fear have emerged with associated behavioural response patterns, and that behaviour is less rigidly controlled by instincts.
So it seems that instinctive behaviour can be modified by feelings of care and affection and also by experience, particularly when repeated frequently.
Neural pathways are created and strengthened by being used, others weakened by not being used. We react accordingly and it seems as if memories are being created which modify instinctive behavioural responses.
It also seems that instinctive behaviour has to be controlled, and modified according to the environment in which we find ourselves, in every generation, and that the mammalian and human parts of the brain play a major part in this.

ADAPTING TO THE WORLD IN WHICH WE LIVE: CHANGING BEHAVIOUR PATTERNS

We adapt to the world in which we live in much the same way. What happens to us and what we do, and what happens as a result, changes neural pathways. A trace is left, neural pathways are changed, memories are formed. Playing is one way of learning how to behave, of learning about social co-operation and conflict, about family relations and about bringing up a family. From infant through child and adolescence to being an adult, we go through a long period in which we learn through playing and by experience. And learning by experience and by gaining knowledge continues while we are alive.
Social responsibility, the caring, giving and sharing with others, the taking on of responsibility for others, including conflict management, can be and is being taught.
What human beings do, what happens to us, is also memorised if thought relevant. These memories can be recalled when required and in this way will affect our future behaviour. Additionally we also absorb information from external memory, from the mass of information now available to us from sources external to ourselves. And the action we take, what we do, depends on evaluating the situation, what we know and how we feel about it. The outcome itself is evaluated and becomes part of our memories.
It seems that on the whole people may not be able to recall feelings, that most people can only recall how they felt about something at the time. Each new experience adds to our knowledge and plays a part in shaping our view of the community and society in which we live, of the world at large, and helps to determine our behaviour.

EVALUATION AND UNDERSTANDING

Behaviour of the primitive animals from which human beings evolved is instinctive. Which means that behaviour relating to survival, such as attack, defence or sexual, is automatic. Territory is acquired by force and defended. Might is right.
The mammalian brain includes the older reptilian brain and is linked to it. With the mammalian brain emerged feelings such as attachment, fear and anger together with associated behavioural response patterns. Mammalian behaviour is less rigidly controlled by instincts. The human brain includes the mammalian brain and human emotional responses depend on neuronal pathways which link the right hemisphere to the mammalian brain.
It takes human beings many years to bring up their children and it is the right hemisphere which is concerned with a wide range of emotions and feelings of care and affection for the young and for the family, and then for other people and the community.
For human beings, primitive (reptilian) instinctive urges and behaviour are overlaid by mammalian care and affection for one's young and human care and affection for one's family and community. Behaviour is aimed at survival of the young and of the family, and then is for the good of family, other people, community.


The right hemisphere is linked to the primitive older part of the brain which has no verbal, semantic or reasoning ability and so functions subconsciously (below the level of consciousness). Hence the right hemisphere communicates with the 'subconscious' functions of the older part of the brain by using images. Communicating by using images is fast.
And so the right hemisphere communicates using images and has highly developed spatial abilities, is intuitive and imaginative, is concerned with emotions and feelings. Speech, that is thinking and communicating by using words, seems to have evolved later. The left hemisphere communicates by using words, has highly developed verbal and semantic abilities, is logical and systematic, concerned with matters as they are. Images may be described, or transformed into a narrative, by the left hemisphere.

Hence behaviour is not only determined by feelings but also by knowledge, understanding and reason.
So the human brain includes the processing and memorising of images and of their components, and the development of language and corresponding mental processing connected with memory and memorising. It also includes a wide range of emotions, of feelings, of care and affection, and the capability for objective and logical thinking and evaluation. And the later development of written languages and artificial images. We are continually gaining information by learning, by reading or studying, learning from the experiences of others, gaining verbal information and pictorial images from external memory. The mind evaluates this incoming information and decides what is to be retained and memorised, rejecting the remainder. Information about what has been happening to oneself is treated in the same way.
And when something is happening to oneself, when one is doing something or planning to do something, we recall relevant information from memory, add other available information, and before taking action we evaluate all the information we now have. What happens as a result of the action we took is again evaluated and memorised for later use.

Hence behaviour is not only determined by feelings but also by knowledge, understanding and reason.
