Psychotherapy by Hugo Münsterberg (world of reading .TXT) 📕

But if every belief is such a new motor setting, then we are evidently brought back to the mechanism which was essential for every suggestion of action on the one side and for every process of attention on the other side, namely, the mechanism of antagonistic movements. To prepare ourselves for one line of action means to close beforehand the channels of discharge for the opposite. The suggestible mind sees the man with a gun on the wayside because he is preparing himself in his expectation for the appropriate action; he is ready for the fight or ready to run away, and every line of the tree trunk is apperceived with reference to this motor setting. The smell, on the other hand, has disappeared under the influence of the suggestion because a new motor adjustment has set in, in which he is prepared to act as if there were no smell.

The difference between suggestion and attention lies thus only in this: the motor response in attention aims towards a fuller clearness of the idea, for instance, by fixating, listening, observing, searching; while the motor response in suggestion aims towards the practical action in which the object of the idea is accepted as real. In attention, we change the object in making it clearer; in suggestion, we change ourselves in adapting ourselves to the new situation in which we believe. If you consider attention as a psychophysical process open to physiological explanation, you have surely no reason to seek anything mysterious in the process of suggestion; and no new principle is involved, if we come from the effect of the smallest suggestive hint to the complex and powerful suggestions which overwhelm the whole personality.

The two great types of suggestion, the suggestion of actions and the suggestion of ideas, have now come nearer together since we have seen that the suggestion of ideas is really a suggestion of the practical acceptance of ideas, and that means, of a preparation towards a certain line of action. In the one case I suggest the idea of a certain action and this motor idea leads to the action itself, and in the other case I suggest a certain preparatory setting for action and that will lead to the appropriate action whenever the time for action comes. Every suggestion is thus ultimately a suggestion of activity. The most effective suggestion for an action results, of course, if both methods are combined, that is, if we suggest not only the will to perform the action, but at the same time the belief that the end of the action will be real. Suggestion reaches us usually from without. Yet there is again no new principle involved, when the new motor setting results from one's own associations and emotions. Then we speak of auto-suggestion. It is the same difference which exists between the attention called forth through an outer impression and the attention directed by our own will. Loud noise demands our attention, and even a whispered word may awaken associations which stir up the attention. In both cases the channels for adjustment become opened without our intention. But if we are expecting something of importance, if we start to watch a certain development and to find something which we seek, we open the channels by our own effort beforehand and produce our own settings thus through a voluntary attention. In this way suggestion too may start from without,—by a spoken word, by a movement, by a hint; or may start within us and may give us our caprices and our prejudices.

We must not neglect one other feature of the suggestion. Not every proposition to action or to belief can be called a suggestion. Essential too remains the other side of it, the overcoming of the resistance. A mere request, "Please hand me the book on the table," or a mere communication, "It rains," may produce and will produce the fit motor response, the movement towards handing over the book or opening of the umbrella, and yet there may be no suggestive element involved. We have a right to speak of suggestion only if a resistance is to be broken down, that is, if the antagonistic impulse, or the motor setting for the antagonistic action is relatively strong. If I say to the boy, "Hand me the book," when he was anxious to hide the book from my eyes and thus had the wish not to hand it to me and the tone of my request overwhelmed his own intention, then to be sure suggestion is at work. The stronger the resistance, the greater the degree of suggestive power which is needed to overcome the motor setting. If I say to the normal man, "It rains," while he sees the blue sky and the dry street, his impression will be stronger than my suggestion; but if he is suggestible and I tell him that it will rain, he may accept it and take an umbrella on his walk, even if no indication makes a change of weather probable. The present impression of the dry street was strong enough to resist the suggestion, the imaginative idea of that which is to be expected in the next hour was too weak, and was overwhelmed by the suggestion of the weather prophecy.

It is clear that the whole suggestive effect, being one of a new motor setting, depends thus entirely on the equilibrium of the personality which receives the suggestion. Every element which reaches the mind through sense organs or through associations must have influence in helping the one or the other side, that is, in opening the channels of action in the suggested direction or in the antagonistic one. The results appear surprising only if we forget how endlessly complex this psychomotor apparatus really is. If we disregard this complexity we may easily have the feeling that one person has an unexplainable influence over another, as if the will of the one could control in a mysterious way the will of the other. But as soon as we see that every action is the result of the coöperation of hundreds of thousands of psychomotor impulses which are in definite relation to antagonistic energies, and that the result depends upon the struggling and balancing of this most complex apparatus, then we understand more easily how outer influences may help the one or the other side to preponderance: as soon as the balance turns to the one side, a completely new adjustment must set in. And we understand especially that there is nowhere a sharp demarcation line between receiving communications and receiving suggestions. By small steps suggestion shades over into the ordinary exchange of ideas, propositions, and impressions, just as attention shades over into a neutral perception.

To be suggestible means thus to be provided with a psychophysical apparatus in which new propositions for actions close easily the channels for antagonistic activity. Such an apparatus carries with it the disadvantage that the personality may too easily be guided contrary to his own knowledge and experience. He will be carried away by every new proposition and will accept beliefs which his own thoughts ought to reject. On the other hand, it has the advantage that he will be open to new ideas, be ready to follow good examples, never stubbornly close his mind to the unaccustomed and the uncomfortable. It is easy to determine the degree of suggestibility. Take this case. I draw on the blackboard of a classroom two circles of an equal size, and write in the one the number fourteen and in the other the number eighty-nine, and ask the children which is the larger circle. The suggestible ones will believe that the circle with the higher number in it is really larger than the other, the unsuggestible children will follow the advice of their senses and call both equal, and there may be a few children with negative suggestibility who would call the circle with the higher number the smaller circle. What happened to the suggestible ones was that the higher number brought about a motor attitude which faced that whole complex as being more imposing and this new motor setting was with them strong enough to overcome the motor adjustment which the circles alone produced. Such experiments of the psychological laboratory can be varied a thousandfold, and it might not be unwise to introduce them into many practical fields. Everybody knows for instance how much may depend upon the suggestibility of the witness in court. The suggestible witness believes himself to have seen and heard what the lawyer suggests. The memory picture which such a witness has in mind offers, of course, much less resistance to the opposite action and attitude and belief than the immediate impression. If I show the witness a colored picture of a room and close the book and ask him whether there were three or four chairs in the picture and whether the curtain was green or red, the suggestible man will decide for one or the other proposition, even if there were only two chairs and a blue curtain. The perception would have resisted the suggestion, the fading memory image cannot resist it. Thus suggestibility is really a practical factor in every walk of life. And it is in the highest interests of psychotherapy that this intimate connection between suggestion and ordinary talk and intercourse, between suggestion and ordinary choice of motives, between suggestion and attention be steadily kept in view and that suggestion is not transformed into a kind of mysterious agency.

To be sure, the importance of suggestion for psychotherapy is not confined to these suggestive processes of daily life. They play a rôle there, as we shall see, and we shall claim that even the mere presence of the physician may have its suggestive power and so may every remedy which he applies. But no doubt many of his suggestive effects depend on a power which far transcends the suggestions of our daily life. Yet the psychologist must insist again that no new principle is involved, that even in the strongest forms of suggestion, in hypnotism, nothing depends upon any special influence emanating from the mind of the hypnotizer or upon any special power flowing over from brain to brain; but that everything results from the change of equilibrium in the psychomotor processes of the hypnotized, and thus upon the interplay of his own mental functions. All that is needed is a higher degree of suggestibility than is found in the normal life. In a more suggestible mind even the direct sense impressions may be overwhelmed by the proposition for an untrue belief and the strongest desires may yield to the new propositions of action. This library may then become a garden where the hypnotized person picks flowers from the floor, and the wise man stands on one leg and repeats the alphabet, if the hypnotizer asks him to do so. Let us consider at first this extreme case. By a few manipulations I have brought a man into a deep hypnotic state. He is now unable to resist any suggestion, either suggestion of impulse or suggestion of belief, and as every one of the hypnotic phenomena can be explained in this way, we may claim that the hypnotic state is in its very nature a state of reënforced suggestibility. Whether I say, "You will not move your arm," or whether I say, "You cannot move your arm," awakening in the one case the impulse to the suppression of the movement, in the other case the
