3. THE RESEARCH, ITS OBJECTS AND METHODS:
These general orientation tests for a norm and its pathological variation were the basis upon which I proceeded on broader lines with a further and more exhaustive investigation with the following points in view:
To what extent is visualization weak?
Is it weaker in the worst cases?
Is it less and less weak as cases appear less severe?
Is it the same for past, present and future memories?
Is visualization equally at fault in all sensory areas of the cortex?
Do cases approach normal visualization processes in proportion as they progress in their cure? and
Lastly, numerous other minor queries presented themselves.
All these questions were answered in the following research, which after thus much orientation found a more complete and final form.
In order to answer these questions I formulated the following series of tests to the number of twenty-four in all, and asked them in series to nineteen stutterers, making almost four hundred tests:
1. Speech:
Say, Today is sunny.
The dog ran across the street.
Submarines will sink all the steamers.
2. Motor:
Do you dance?
Did you ever skate?
Would you sew for a living?
3. General Sensory:
How does a pinch feel?
Did you ever get hurt?
What would you like to do if it was very hot next summer?
4. Hearing: (Eyes closed)
Do you hear anything?
Did you ever hear a rooster crow?
What sounds would you like to hear next summer?
5. Sight: (Eyes closed)
What do you see now?
What did you see yesterday?
What would you like to see next summer?
6. Smell: (Eyes closed) (Pen to nose)
Do you smell anything?
What have you told by smell?
What would you like to smell next summer?
7. Taste: (Eyes closed)
Do you taste anything?
What have you been able to tell by the taste?
What would you like to taste next summer?
8. Muscle Sense: (Eyes closed)
Put one arm up; the other like it.
Put one arm up, down; the other like it.
How would you hold a hand to read from it?
This long series of questions with careful introspection tests upon the content of consciousness constituted then my main research in the field of stuttering. Perhaps further details in explanation of the questions chosen is unnecessary. Three or more questions on introspection were asked at each test.
4. FINAL DETAILED RESULTS are found in the following conclusions as drawn from 1440 answers.
In our average conversation a visual picture is created before we begin utterance. Severe stutterers never visualize at all. In direct proportion that these cases become less severe, does visualization increase in frequency, strength and continuation in consciousness before and during utterance.
When severe stutterers are free from spasms they visualize, and when they stutter they do not visualize.
When mild cases are free from spasms, they visualize, and when they stutter they fail to visualize.
In a word, when visualization is present stuttering is absent; when visualization is absent stuttering is present.
This is true not only of EACH UTTERANCE, in most cases, but is true of severe as well as mild forms as a whole.
Stutterers gain in visualization as they approach cure.
For past, present and future memories: visualization is slightly more frequent for past and future.
Therefore stuttering is an indication of absent or weak visualization either in isolated words, occasional stutterers, mild stutterers or the severest type, either before or during speech, or both.
The slump, then, in personality which I showed last year as the main thing in stuttering as its cause and condition, is thus found by further psychological analysis, to be a slump in the power to consciously visualize.
By personality I mean as mentioned above the composite of collaborative activities that lie between the low sensory repository areas and the low motor expression areas. In other words, personality includes all those collaborative processes that lie between the sensory intake areas and the motor output areas; in a word, any unexpressed use the mind makes of its intake. Conscious visualization is a part of personality processes, then. In my last year's paper([1]) the whole matter was left vague. Here something definite and constant is found. In other words the psychoanalytical method revealed no conscious subconscious cause. Granted there is room here to "interpret" (or create according to Freudian mechanisms) a definite subconscious complex, a step which I could not feel justified in taking; I leave this to better psychoanalysts than I. For me to twist stutter phenomena to comply to a theoretical complex is unscientific to say the least. But the psychological method—as represented by this paper—shows a definite constant cause for all the phenomena of stuttering.
FAULTY VISUALIZATION EXPLAINS ALL PHENOMENA:
Upon this basis of an involved visualization all the intricate phenomena of stuttering may be explained. Let us take some of these up in detail.
THE START. Visualization processes are a matter of growth through exercise and development and use from the sensory area mostly of the eye. If these processes in their early start and evolution receive a setback through the treatment of people in the environment, such as interruptions of their early speech efforts, constant inattention of those to whom they speak, and persistent refusal by older people to answer questions propounded or the allowing of the little one to ask the same question without hopes of answer for a great number of times, these visualization processes receive a setback. This kind of treatment in the home is one of the chief causes of the slump of visualization processes. Another cause is hearing other stutterers interrupt their own visualization processes as they stutter; and still other minor causes may be almost any psychic trauma; these traumata, such as an operation, an accident or a severe illness, are sufficient to bring to the surface or intensify a growing lack of visualization that has been started by bad environment long before.
THE DEVELOPMENT OF STUTTERING. When the habit of visualization is lessened, the action upon speech is the same as the withdrawal of an inhibiting or regulating reflex arc.
It is thus that visualization processes act like reflex inhibition. When visualization is present a higher inhibition arc is functioning and we have a normal speech as a consequent reflex expression. When and in proportion as visualization is absent this higher inhibition arc is not functioning; and the speech thus uncontrolled flies away in spasms which we call stutter. It should be called an exaggerated or uninhibited speech reflex.
The stutter, then, is merely the externalization of an exaggerated reflex of motor speech, exaggerated through the loss of the inhibitory action of a more or less weakened visualization process.
Not only does this explain the phenomena at large but seems to be a satisfactory explanation for all its intricate, minute details. Some examples may, perhaps, be welcome at this point. I say to two stutterers: "Tell your first name." One of them stutters and the other one does not. On furthering questioning, it is found that the one who did not stutter visualized, and the one who did stutter did not visualize.
CONCRETE: These conditions are also seen when stutterers talk about concrete and abstract matters or when they promulgate some important plea that cannot be visualized. On concrete matters that can be easily visualized the stuttering is gone; and on abstract matters where visualization is hard, the stuttering again appears.
ANGER: In anger, when an intense visual picture is presented and occupies the mind, there is then no stuttering, and also in other similar situations there are periods when the individual is abandoned to some visual concept which acts in the same manner.
SINGING: We all know that stutterers can sing without stuttering. The process here is a similar one; only that there is held up over the speech before utterance an auditory image of a melody in place of the visual image as held in normal speech. This auditory image may be more easily applicable as supplying the needed inhibition reflex arc than the visual because it is nearer to the speech area.
PRAYER: For the same reason prayer is uttered without stuttering when there is faith enough in a God to hold an image of Him during utterance. There may also be other images held during prayer.
FAMILIAR SIGHTS: Familiar sights are less stuttered upon than the detailing of situations that are less familiar and therefore can be less well visualized. This is also true of sights that have been recently seen or that have been repeatedly seen, or that in some other way have been made intense as pictures in the visual field.
AS CURE PROCEEDS: In the process of recovery where visualization is seen to increase as the stutter decreases, there is another illustration where this visualization attitude explains the whole situation. I have taken a severe stutterer and told him a story that could be well pictured, got him to work up the pictures properly by several complicated processes (which we will not consider now) and when he had them well in hand, I have seen him stand up and relate the story from beginning to end with little or no stuttering If at any point he would trip up, the inevitable confession would be that at that point he dropped the picture, or, in other words, the visualization could not be held over in its inhibitory action; and therefore the stutter came. On further request to hold it over that point, the same passage would be again expressed smoothly if he succeeded in holding the picture.
This constancy, this presence and absence of the picture, its presence to make smooth talk and its absence to cause stuttering, is so constant at every turn of the situation, that I would offer it as a new interpretation of all these phenomena. I know of no other interpretation that can EXPLAIN EVERYTHING UNDER ONE HEAD as does this absence, weakness or interruption of visualization processes.
TERMINOLOGY. We have found in our orientation tests that in a vague way the visualization was at fault. We have also found in normal individuals that a marked visualization was an automatic process that preceded speech, and lasted during utterance; and we have found in the long series of stutterers that visualization is entirely absent in severe cases; that it is weak in milder forms; that it is intermittent in most cases, and that on words that are smooth it always appears, and in occasional stutter it is as occasionally absent.
We have also found that the form of visualization common in normal speech is the visualization of eye sensations; that in unusual situations we may have visualizations from other sense areas, such as the ear, taste or smell, but these are the RARE EXCEPTION.
From all this data it would naturally follow that some sort of term is needed to designate this condition. Last year I probed to find such a term without much success.
At present I see no reason why it should not be called an Asthenia; it is surely the weakening of a mental process that is strong in normal individuals. The evidence here presented shows that. I doubt whether there is any marked pathological change, since the individual may be educated out of it; but this does not necessarily follow as proven with my dog in Berlin.[2] As a general designation, then, I should consider Asthenia as apropos.
One objection to this is that the weakness is by this terminology lacking in localization. Our data above has shown us that the location of the trouble is visual; that is, it is situated about a centre of sensory registration that deposits data from the eye; this must naturally then be located somewhere in or near the cuneus. We could therefore add to the terminology this idea of a minute localization and call it a Centre Asthenia.
Some may prefer to carry the matter one step farther and add the name of the centre in which this weakness is located, but I fear if I take this step and complete my terminology by the word "Visual Centre Asthenia," it will, as such, not cover quite all the cases, for I find that sometimes the visualization is absent in other areas as well, and also the holding of an emotion of pleasure or pain and of other dominating mental attitudes that are sometimes visualized would not, therefore, be included. I would therefore retract the broader claim in order to place the term on a conservative basis and call the essence of the lesion simply no more or less than a Centre Asthenia. As well as visual Asthenia, the following terms might be considered as applicable: collaborative centre asthenia; imaginative centre asthenia; visual creative centre asthenia; picture producing centre asthenia. We say neurasthenia when the trouble is not in the nerves as such, so much as it is in the collaborative centres. More of this later. Here in stuttering the trouble is also collaborative, and we can be still more definite than that and say the trouble is with the collaboration of visualization. So if I were forced, however, to choose one term from all these, my choice would be "Visual Centre Asthenia." This indicates a new and rational treatment. But of this later.
SUMMARY: Psychoanalysis reveals stuttering as some vague trouble in the personality[1]. Psychological Analysis shows stuttering is an absent or weak visualization at the time of speech. This new concept of stuttering as faulty visualization may be called Visual Centre Asthenia. This lack or weakness in visualization accounts for all the numerous phenomena of stuttering in severe, medium, or mild cases. A new treatment is indicated.
