Psychotherapy, Hugo Münsterberg [dar e dil novel online reading txt] 📗

an impressiveness and dignity that every opposite thought disappears, while others throw out words which are forgotten. On the other hand, the readiness to accept suggestions is evidently also quite different with different individuals. From the most credulous to the stubborn, we have every degree of suggestibility, the one impressed by the suggestive power of any idea which is brought to his mind, the other always inclined to distrust and to look over to the opposite argument. Such a stubborn mind is indeed not only without inclination for suggestions, but it may develop even a negative suggestibility; whatever it receives awakens an instinctive impulse towards the opposite. Moreover we are all in different degrees suggestible at different times and under various conditions. Emotions reënforce our readiness to accept suggestions. Hope and fear, love and jealousy give to the impression and the idea a power to overwhelm the opposite idea, which otherwise might have influenced our deliberation. Fatigue and intoxicants increase suggestibility very strongly. To look out on a wider perspective, we may add at once that an artificial increase of suggestibility is all which constitutes the state of hypnotism.

At first, however, we want to understand the ordinary process of suggestion in that normal form in which it enters into every hour of our life and into every relation of our social intercourse. But if we begin to examine the structure of the process, we can no longer be satisfied with the vague reference to ideas and their opposites. What does it mean after all if we speak of opposite ideas? Can we not entertain any ideas peacefully together in our consciousness? From a logical standpoint, ideas may contradict each other, but that refers to their meaning. As mere bits of psychological experience, I may have any ideas together in my consciousness. I can think summer and winter or day and night or right and left or black and white or love and hate in one embracing thought. As mere mental stuff, the one idea does not interfere with the other. On the other hand, this is evident: I cannot will to turn to the right and to turn to the left at the same time. There may be a wrangling between those two impulses, but as soon as my will stands for the one, the other is really excluded. Any action which I am starting to do thus crowds out the impulse to the opposed action.

In the sphere of psychological facts, we have here indeed the only relation between two happenings which necessarily involves an opposition. We could never understand why one brain cell might not work together with any other brain cell, but we do understand that nature must provide for an apparatus by which the impulse to one action makes the impulse to the opposite action ineffective. There is no action which has not its definite opposite. The carrying out of any impulse involves the suppression of the contrary impulse, and the impulse not to do an action involves the suppression of the impulse to do it. When we spoke of the relations of mind and brain, we mentioned that such a corelation of mental centers indeed exists. Physiological experiments have demonstrated that the activity of those centers which stimulate a certain action reduce the excitability of those brain parts which awaken the antagonistic action. As far as the world of actions is concerned, the mechanism of the process of suggestion thus seems not inaccessible to a physiological understanding.

Various ideas of movements to be carried out are struggling for control in the cortex of the brain. That is the normal status which precedes any decision. The channels of motor discharge are open for both possibilities; we may turn to the right or to the left. Then the play of associations begins. A larger and larger circle of ideas surrounds the idea of the one and of the other goal. Those ideas awaken emotions. On the one side may call our duty and on the other side our pleasure. Larger and larger parts of the central content of our consciousness, of our own personality, become involved; our principles and maxims, our memories, our hopes and fears, enter into the battle until deeper strata of the idea of ourselves enter into a firm association with the one side, reënforcing, perhaps, the idea of the goal at the right. This opens wide the channels of discharge for the movement to the right and inhibits thereby the excitability of the center which leads to the opposite action. The channel of discharge to the movement towards the left becomes closed, the idea of that movement fades away and becomes inhibited: we are moving towards the right. The outcome was the product of our total personality.

But this result would have been different, if from the start the channels of discharge had not been equally open for both possible movements, and if thus the relative resistance to the impulse had not been equal on both sides. If, for instance, we had gone from the given point frequently to the left, as a result of the habit and training, the impulse to the left would have found less nervous resistance. The channels would have become widened by the repetition and the opposite channels would have been somewhat closed by the lack of use. Or if instead of such previous habit, we should see at the decisive moment others turning to the left, the impression would have become the starting point for a reaction of mere instinctive imitation. While we might not have followed that imitative impulse at once, yet the channels would have been widened, the discharge in the direction would have been prepared by it, the resistance would have been lowered and the chances for the opposite movement would have been decreased. Those people who moved to the left gave us by their action the same kind of an impulse which they would have furnished if they had begged us with words, or if they had ordered us to follow them with authoritative firmness. In each of these cases, the influence would have amounted to a suggestion. Whether we watched the movements of other people or whether their words made an impression on us, in either case the way became prepared for a certain line of action and therefore the way for the opposite action became blocked. The final outcome was thus no longer an entirely free play of motor ideas, but there was a little inequality in play. The one had from the start a better chance, the other was from the start laboring under difficulties. The suggestion of actions is thus nothing but making use of the antagonistic character in the nervous paths which start from the motor centers. That all such phrases as the opening and the closing, the widening and blocking, of channels of discharge are only metaphors hardly needs special emphasis. Instead of such comparisons, we ought rather to think of chemical processes which offer various degrees of resistance to the propagation of the nervous excitement.

We see from here the direction in which many psychotherapeutic efforts must lie, efforts which are entirely within the limits of the daily normal experience, and belong to the medical practice of every physician, yes, to the helpful influence of every man in practical life. The intemperate man may suffer from his inability to resist his desire for whiskey. The idea of his visit to the saloon finds the channels of discharge open. We argue with him, we tempt him by attractions which lead to other ways, we suggest to him that he spend those evening hours perhaps with friends or with books for which we awaken his interest; we do it as impressively as we can, we appeal to his friendly feeling for us; and if again the hour comes in which the desire for the artificial stimulation sets in with a motor impulse towards the bottle, the channels for discharge have now been blocked. The idea of the opposite action arises, it associates itself with the emotions which we stirred up in his mind, it associates itself with the respect for the adviser, and thus new clusters of thought reënforce that idea of action which we suggested, and this opposite line of action now finds a minimum resistance because our appeal has opened beforehand the gate. The desire for the book works itself out into action while the desire for the cup finds increased resistance.

Just this is the kind of suggestion with which we correct faulty action everywhere in our social circle; and yet small steps lead on from here to the case where perhaps the desire for alcohol has reached that pathological intensity in which the equilibrium is entirely disturbed and cannot be repaired without suggestions of a much more powerful character, given in a state of artificially increased suggestibility—in hypnotism. The principle of opening certain channels of discharge for the purpose of closing the opposite channels remains in the extreme case the same as in the more ordinary cases. The impulse to drink is a positive one, but the principle is not different where the impulse is negative. A friend who comes from the quiet country may feel unable to pass the busy square of the city. The fear of an accident holds back his steps, he cannot give the impulse to walk through the crowded rush of vehicles. Now either by words of advice, by persuasion or by showing the way, we may apply our suggestion, we open the channels of discharge for the necessary movements and thus decrease the excitability of those centers in which nervous fear was playing. And again small steps lead from here to the case of the psychasthenic sufferer whose phobia does not allow him to cross any square and where reënforced suggestion has to break open the ways for the walking movement when the square is reached.

Thus we are not far from a causal understanding of suggestive influences wherever actions are concerned, where movements are to be reënforced or to be suppressed and where antagonism of the motor paths is involved. But that does not seem to lead us nearer to the much larger group of states in which the whole suggestive process concerns apparently the interplay of ideas alone, where not actions but impressions are controlled by suggestion, where not impulses but thoughts are strengthened or inhibited. Here lies the real psychophysical problem which has been by far too much neglected in scientific psychology and has almost been hidden and made to disappear in the wonderful accounts of the hypnotists. But all those mysterious stories as to the achievements of suggestion cannot help so long as we do not understand the working of the process, and we shall have the better chance to understand it the more we keep away from the uncanny and mysterious results which refer to the most complex conditions, and rather seek to analyze the state in its simplest forms and compare it with other simple mental processes. The psychology of suggestion has suffered too much by the fascination which its most complex forms exert on a trivial curiosity.

Yet the problem of suggestion in the field of ideas stands after all not isolated. Instead of connecting it with the weird reports of mystic influence from man to man, let us rather link it with the simple experience of attention. There is no pulse-beat of our life in which attention does not play its little rôle. But does not attention share with suggestion the characteristic feature that some contents of consciousness are reënforced and others are suppressed? This negative, this suppressing character of attention is not a chance by-product, it is most essential. There is no attention without it. If I am studying, I do not hear the
