For example, patients speak of an aunt and later, without noting the mistake, call her “my mother,” or designate a husband as a “brother.” In this way they attract my attention to the fact that they have “identified” these persons with each other, that they have placed them in the same category, which for their emotional life signifies the recurrence of the same type. Or, a young man of twenty years presents himself during my office hours with these words: “I am the father of N. N., whom you have treated--pardon me, I mean the brother; why, he is four years older than I.” I understand through this mistake that he wishes to express that, like the brother, he, too, is ill through the fault of the father; like his brother, he wishes to be cured, but that the father is the one most in need of treatment. At other times an unusual arrangement of words, or a forced expression, is sufficient to disclose in the speech of the patient the participation of a repressed thought having a different motive. Hence, in coarse as well as in finer speech disturbances, which may, nevertheless, be subsumed as “speech-blunders,” I find that it is not the contact effects of the sound, but the thoughts outside the intended speech, which determine the origin of the speech-blunder, and also suffice to explain the newly formed mistakes in speech. I do not doubt the laws whereby the sounds produce changes upon one another; but they alone do not appear to me sufficiently forcible to mar the correct execution of speech. In those cases which I have studied and investigated more closely they merely represent the preformed mechanism, which is conveniently utilized by a more remote psychic motive. The latter does not, however, form a part of the sphere of influence of these sound relations. _In a large number of substitutions caused by mistakes in talking there is an entire absence of such phonetic laws._ In this respect I am in full accord with Wundt, who likewise assumes that the conditions underlying speech-blunders are complex and go far beyond the contact effect of the sounds. If I accept as certain “these more remote psychic influences,” following Wundt’s expression, there is still nothing to detain me from conceding also that in accelerated speech, with a certain amount of diverted attention, the causes of speech-blunder may be easily limited to the definite law of Meringer and Mayer. However, in a number of examples gathered by these authors a more complicated solution is quite apparent. In some forms of speech-blunders we may assume that the disturbing factor is the result of striking against obscene words and meanings. The purposive disfigurement and distortion of words and phrases, which is so popular with vulgar persons, aims at nothing else but the employing of a harmless motive as a reminder of the obscene, and this sport is so frequent that it would not be at all remarkable if it appeared unintentionally and contrary to the will.
