some adjacent association in his hysterics. If he pricked the anæsthetic hand of the patient without his noticing the prick, he thought of "points"; if the anæsthetic finger was moved, he thought of "sticks" or "columns." When the anæsthetic hand, concealed from the patient's sight by a screen, writes "Salpêtrière," she sees in front of her the word "Salpêtrière" in white writing on a black ground. This recalls the experiments above referred to of Guinon and Sophie Waltke.
We thus find in our subject, at a time when there was nothing to indicate the later phenomena, rudimentary automatisms, fragments of dream manifestations, which imply in themselves the possibility that some day more than one association would creep in between the perception of the dispersed attention and consciousness. The misreading shows us, moreover, a certain automatic independence of the psychical elements. This occasionally expands to a more or less fleeting dispersion of attention, although with very slight results which are never in any way striking or suspicious; this dispersedness approximates to that of the physiological dream. The misreading can be thus conceived as a prodromal symptom of the later events; especially as its psychology is prototypical for the mechanism of somnambulic dreams, which are indeed nothing but a many-sided multiplication and manifold variation of the elementary processes reviewed above. I never succeeded in demonstrating during my observations similar rudimentary automatisms. It would seem that in course of time the states of dispersed attention, to a certain extent beneath the surface of consciousness, at first of low degree have grown into these remarkable somnambulic attacks; hence they disappeared during the waking state, which was free from attacks. So far as concerns the development of the patient's character, beyond a certain not very extensive ripening, no remarkable change could be demonstrated during the observations lasting nearly two years. More remarkable is the fact that in the two years since the cessation (complete?) of the somnambulic attacks, a considerable change in character has taken place. We shall have occasion later on to speak of the importance of this observation.
Semi-Somnambulism.—In S. W.'s case the following condition was indicated by the term semi-somnambulism. For some time after and before the actual somnambulic attack the patient finds herself in a state whose most salient feature can best be described as "preoccupation." She only lends half an ear to the conversation around her, answers at random, often gets absorbed in all manner of hallucinations; her face is solemn, her look ecstatic, visionary, ardent. Closer observation discloses a far-reaching alteration of the entire character. She is now serious, dignified; when she speaks her subject is always an extremely serious one. In this condition she can talk so seriously, forcibly and convincingly, that one is tempted to ask oneself if this is really a girl of fifteen and a half. One has the impression of a mature woman possessed of considerable dramatic talent. The reason for this seriousness, this solemnity of behaviour, is given in her explanation that at these times she stands at the frontier of this world and the other, and associates just as truly with the spirits of the dead as with living people. And, indeed, her conversation is usually divided between answers to real objective questions and hallucinatory ones. I call this state semi-somnambulism because it coincides with Richet's own definition. He[25] says: "La conscience de cet individu persiste dans son intégrité apparente, toutefois des opérations très compliquées vont s'accomplir en dehors de la conscience sans que le moi volontaire et conscient paraisse ressentir une modification quelconque. Une autre personne sera en lui qui agira, pensera, voudra, sans que la conscience, c'est à dire le moi réfléchi conscient, aît la moindre notion."
Binet[26] says of this term: "Le terme indique la parenté de cet état avec le somnambulisme véritable, et en suite il laisse comprendre que la vie somnambulique qui se manifeste durant la veille est réduite, déprimée, par la conscience normale qui la recouvre."
Automatisms.
Semi-somnambulism is characterised by the continuity of consciousness with that of the waking state and by the appearance of various automatisms which give evidence of an activity of the subconscious self, independent of that of consciousness.
Our case shows the following automatic phenomena:
(1) Automatic movements of the table.
(2) Automatic writing.
(3) Hallucinations.
1. Automatic Movements of the Table.—Before the patient came under my observation she had been influenced by the suggestion of "table-turning," which she had first come across as a game. As soon as she entered the circle there appeared communications from members of her family which showed her to be a medium. I could only find out that, as soon as ever her hand was placed on the table, the typical movements began. The resulting communications have no interest for us. But the automatic character of the act itself deserves some discussion, for we may, without more ado, set aside the imputation that there was any question of intentional and voluntary pushing or pulling on the part of the patient.
As we know from the investigations of Chevreul,[27] Gley, Lehmann and others, unconscious motor phenomena are not only of frequent occurrence among hysterical persons, and those pathologically inclined in other directions, but they are also relatively easily produced in normal persons who show no other spontaneous automatisms. I have made many experiments on these lines, and can confirm this observation. In the great majority of instances all that is required is enough patience to put up with an hour of quiet waiting. In most subjects, motor automatisms will be obtained in a more or less high degree if contra-suggestions do not intervene as obstacles. In a relatively small percentage the phenomena arise spontaneously, i.e. directly under the influence of verbal suggestion or of some earlier auto-suggestion. In this instance the case is powerfully affected by suggestion. In general, the particular predisposition is subject to all those laws which also hold good for normal hypnosis. Nevertheless, certain special circumstances are to be taken into account, conditioned by the peculiarity of the case. It is not a question of a total hypnosis, but of a partial one, limited entirely to the motor area of the arm, like the cerebral anæsthesia produced by "magnetic passes" for a painful spot in the body. We touch the spot in question employing verbal suggestion or making use of some existing auto-suggestion, using the tactile stimulus which we know acts suggestively, to bring about the desired partial hypnosis. In accordance with this procedure, refractory subjects can be brought easily enough to an exhibition of automatism. The experimenter intentionally gives the table a slight push, or, better, a series of rhythmic but very slight taps. After a short time he notices that the oscillations become stronger, that they continue although he has interrupted his own intentional movements. The experiment has succeeded, the subject has unsuspectingly taken up the suggestion. By this procedure much more is obtained than by verbal suggestion. In very receptive persons and in all those cases where movement seems to arise spontaneously, the purposeful tremulous movements,[28] not perceptible by the subject, assume the rôle of agent provocateur.
In this way persons who, by themselves, have never obtained automatic movements of a coarse calibre, sometimes assume the unconscious guidance of the table-movements, provided that the tremors are strong and that the medium understands their meaning. In this case the medium takes control of the slight oscillations and returns them considerably strengthened, but rarely at exactly the same instant, generally a few seconds later, in this way revealing the agent's conscious or unconscious thought. By means of this simple mechanism there may arise those cases of thought-reading so bewildering at first sight. A very simple experiment, that succeeds in many cases even with unpractised persons, will serve to illustrate this. The experimenter thinks, say, of the number four, and then waits, his hands quietly resting on the table, until he feels that the table makes the first inclination to announce the number thought of. He lifts his hands off the table immediately, and the number four will be correctly tilted out. It is advisable in this experiment to place the table upon a soft thick carpet. By close attention the experimenter will occasionally notice a movement of the table which is thus represented.
