"The attempt to repress from consciousness into the unconscious certain trends of thought or emotions, usually of a sexual nature, is the chief mechanism in stammering." This is the only place in the article where Dr. Coriat expresses any doubt as to the universal validity of his theory for all cases of stuttering. But I consider this merely as a slip of the tongue or pen, because in the other portions of the paper the conclusion concerning the sexual basis of stammering is unqualifiedly made general, and I find that even on the very next page, at the conclusion of the paragraph of which the sentence just quoted is the beginning, there occurs the statement that "the fear in stammering is a deflection of the repressed sexual impulse or wish." With this beginning Dr. Coriat proceeds to explain: "Thus the repressed thought, because of fear of betrayal, comes in conflict with the wish to speak and not to betray (the secret through words[5]). Hence, the hesitation in speech arises and as the repressed thoughts gradually are forced into the unconscious, there finally develops the defective speech automatism, either stammering or a spastic aphonia. This arises in childhood after the child has learned to speak." [5] Words in parentheses mine but taken from Dr. Coriat's paper; for explanatory purposes. Moreover, "the hesitation of stammerers on certain words or letters is due to disturbing complexes. The stammering does not cause the inhibition, it is the inhibition which is at the bottom of the stammering." "Two types of stimuli lead to stammering, either internal conflicts, or external instigators which throw these conflicts into activity. The internal conflicts are either conscious or unconscious fear of betrayal (and therefore a wish to retain a secret), and this mental attitude leads to the dread of speaking, a genuine conversion of morbid anxiety into defective speech. . . . The external stimuli act like dream instigators, for instance the fear of speaking to relatives or to intimate friends may be based upon the fear that the unconscious wishes may be discovered and this stimulates the unconscious anxiety, whereas with strangers, speech is free, because the dread of discovery is absent." "Thus," says Dr. Coriat, "the beginning of stammering in early childhood . . . is caused by the action of unconscious repressed thoughts upon the speech mechanism, the repressed thought obtruding itself in speech." In brief it is contended by Dr. Coriat that the stammering arises as a defense or compensation mechanism, the object of which is to keep from consciousness certain painful memories and undesirable thoughts, in order that they may not be betrayed in speech. In fact, as Dr. Coriat says, "all stammering, with its hesitation, its fear, its disturbing emotions, is a kind of an association test in everyday life and not a phonetic disturbance. It is a situation phobia, the same as phobias of open or closed places."
