This phenomenon has been designated as paradoxical and contrary to all experience. For it is known that emotionally accentuated things are better retained in memory than indifferent things. This is quite true, but it does not hold for the _linguistic_ expression of an emotionally accentuated content. On the contrary, one very easily forgets what he has said under emotion, one is even apt to contradict himself about it. Indeed, the efficacy of cross-examinations in court depends on this fact. The reproduction method therefore serves to render still more prominent the complex stimulus. In normal persons we usually find a limited number of false reproductions, seldom more than 19-20 per cent., while in abnormal persons, especially in hysterics, we often find from 20-40 per cent. of false reproductions. The reproduction certainty is therefore in certain cases a measure for the emotivity of the test-person. * * * * * By far the larger number of neurotics show a pronounced tendency to cover up their intimate affairs in impenetrable darkness, even from the doctor, so that he finds it very difficult to form a proper picture of the patient's psychology. In such cases I am greatly assisted by the association experiment. When the experiment is finished, I first look over the general course of the reaction times. I see a great many very prolonged intervals; this means that the patient can only adjust himself with difficulty, that his psychological functions proceed with marked internal frictions with _resistances_. The greater number of neurotics react only under great and very definite resistances; there are, however, others in whom the average reaction times are as short as in the normal, and in whom the other complex indicators are lacking, but, despite that fact, they undoubtedly present neurotic symptoms. These rare cases are especially found among very intelligent and educated persons, chronic patients who, after many years of practice, have learned to control their outward behaviour and therefore outwardly display very little if any trace of their neuroses. The superficial observer would take them for normal, yet in some places they show disturbances which betray the repressed complex.
