REPRESENTATION

Sensation and Perception, as considered in the preceding chapter, are what are called by psychologists "Processes of Presentation." By Presentation is meant the direct offering to the consciousness of mental images or objects of thought. If there were no faculty of the mind capable of retaining and re-presenting to the consciousness the impression or record of Perception, we could never progress in knowledge, for each percept would be new each time it was presented and there would be no recognition of it as having been previously perceived, nor would there be any power to voluntarily recall any percept previously acquired. In short, we would be without that power of the mind called Memory.

But, fortunately for us as thinkers, we possess the power of Representation; that is, of reproducing past perceptions and experiences in the shape of mental images or pictures, "in the mind's eye," so to speak, which relieves us of the necessity of directly and immediately perceiving an object each time we desire or are required to think of it. The processes whereby this becomes possible are called the processes of Representation, for the reason that by them past experiences of Perception are re-presented to the consciousness.

The subject of Representation is closely bound up with that of Memory. Strictly speaking, Representation may be said to be one phase of Memory; Association of Ideas another; and the authorities prefer to treat the whole subject under the general head of Memory. We have written a work on "Memory" which forms one of the volumes of the present series, and we have no intention, or desire, to repeat here the information given in that work. But we must consider the subject of Representation at this point in order to maintain the logical unity of the present general subject of Thought-Culture. The student will also notice, of course, the close relation between the processes of Representation and those of the Imagination, which we shall consider in other chapters of this work.

Memory has several phases, the usual classification of which is as follows: (1) Impression; (2) Retention; (3) Recollection; (4) Representation, and (5) Recognition. Each phase requires the operation of special mental processes. Impression is the process whereby the impressions of Perception are recorded or stamped upon the subconscious field of mentality, as the impress of the die upon the wax. Retention is the process whereby the subconsciousness retains or holds the impressions so received. Recollection is the process by which the mind re-collects the impressions retained in the subconsciousness, bringing them again into consciousness as objects of knowledge. Representation is the process whereby the impressions so re-collected are pictured or imaged in the mind. Recognition is the process whereby the mind recognizes the mental image or picture so re-presented to it as connected with its past experience.

As we have stated, we have considered the general subject of Memory in another volume of this series and, therefore, shall not attempt to enter into a discussion of its general subject at this place. We shall, accordingly, limit ourselves here to a brief consideration of the phase of Representation and its cultivation.

Representation, of course, depends upon the preceding phases of Memory known as Impression, Retention and Recollection. Unless the Impression is clear; unless the Retention is normal, there can be no Representation. And unless one recollects there can be no Representation. Recollection (which is really a re-collection of percepts) must precede Representation in the shape of mental images or pictures. Recollection re-collects the mental materials out of which the image is to be constructed. But, as Brooks says: "It is not to be assumed that knowledge is retained as a picture; but that it is recreated in the form of a picture or some other mental product when it is recalled." The process is analogous to the transmutation of the sound-waves entering the receiver of a telephone, into electrical-waves which are transmitted to the receiver, where they are in turn re-transmuted to sound-waves which enter the ear of the listener. It will be seen at once that there is the closest possible relation between the processes of Representation and those of Memory—in fact, it is quite difficult to draw a clear line of division between them. Some make the distinction that Representation furnishes us with an exact reproduction of the past; while Imagination combines our mental images into new products. That is, Representation merely reproduces; while Imagination creates by forming new combinations; or Representation deals with a reproduction of the Actual; while Imagination deals with the Ideal.

Wundt speaking of this difficult distinction says: "Psychologists are accustomed to define memory images as ideas which exactly reproduce some previous perception, and fancy images as ideas consisting of a combination of elements taken from a whole number of perceptions. Now memory images in the sense of this definition simply do not exist.... Try, for instance, to draw from memory some landscape picture which you have only once seen, and then compare your copy with the original. You will expect to find plenty of mistakes and omissions; but you will also invariably find that you have put in a great deal which was not in the original, but which comes from landscape pictures which you have seen somewhere else."

While we generally speak of Representation picturing the recollected percepts, still, we must not make the mistake of supposing that it is concerned with, or limited to, only mental pictures. We are able to represent not only visual percepts but also sounds, smells, tastes or feelings, often so vividly that they appear as almost actually existent. We may also even represent, symbolically the processes of reasoning, mathematical operations, etc. In short nearly, if not all experiences which are possible in Presentation are also possible in Representation.

The phase of Representation, in the processes of Memory, is of course subject to the general laws of the Cultivation of Memory which we have stated in detail in our previous volume on that subject. But there are some special points of development and cultivation which may be considered briefly in this place. In the first place the importance of Attention and clear Perception, as necessary precedents for clear Representation, may be emphasized. In order to form clear mental images of a thing we must have perceived it clearly in the first place. The advice regarding the use of the Attention and Perception given in preceding chapters need not be repeated here, but special attention should be directed toward them in connection with the processes of Representation. If we wish to cultivate the Representative faculties, we must begin by cultivating the Presentative faculties.

Then again we must remember what we have said elsewhere about the facts of development through (1) Use; and (2) Nourishment, in all mental faculties. We must begin to use the faculties of Representation in order to exercise them. We must give them nourishment in the shape of objects of mental food. That is to say we must furnish these faculties with materials with which they may grow and develop, and with exercise in order to strengthen the mental-muscle and also to give the faculties the opportunity to "acquire the knack." The exercises and methods recommended in our chapter on Perception will furnish good material for the Representative faculties' growing requirements. By perceiving the details of things, one is able to reproduce clear mental images of them. In studying an object, always carry in your mind the fact that you wish to reproduce it in your mind later. In fact, if you have the opportunity, let your mind "repeat it to itself" as soon as possible after the actual occurrence and experience. Just as you often murmur to yourself, or else write down, the name of a person or place which you have just heard, in order that you may recollect it the better thereafter, so it will be well for you to "mentally repeat" to yourself the experiences upon which you wish to exercise your Representative faculties.

As to the matter of development and cultivation by Use, we would advise that you begin gradually to train your mind to reproduce the experiences of the day or week or month, at intervals, until you feel that you are developing a new power in that direction. Tonight, if you try you will find that you can reproduce but a very small part of today's happenings with any degree of clearness. How clearly can you image the places you have been, the appearances of the people you have met, the various details of persons and things which you perceived during the experiences of the day? Not very clearly, we dare say. Try again, and you will find that you will be able to add new details. Keep it up until you feel tired or think that you have exhausted all the possibilities of the task. Tomorrow, try it again, and you will find that the second day's experiences are more clearly reproduced in your mind. Each day should find you a little more advanced, until you get to a place where the normal degree of power is attained, when the advance will be slower.

Then, at the end of the week, review its experiences. Do the same the following week. At the end of the month, take a hasty mental trip over the month's experiences. And so on. Exercise, in moderation, along these lines will work wonders for you. Not only will it develop the Representation, but your powers of observation and your general memory will be found to be improved. And, moreover, in "chewing the mental cud" you will think of many things of interest and importance in connection with your work, etc., and your general mental efficiency will be increased for the faculties of the mind are interdependent and share benefits with each other.
