In many insane persons only the disconnected remains or ruins of their stock of words are left, so that their speech resembles that of the child at a certain stage. _Dysphrasia of the Feeble-minded._--The child at first reacts only upon strong impressions, and that often indolently and clumsily and with outcry; later, upon impressions of ordinary strength, without understanding--laughing, crowing, uttering disconnected syllables. So the patient reacts either upon strong impressions only, and that indolently, bluntly, with gestures that express little and with rude words, or he still reacts upon impressions of ordinary strength, but in flat, silly, disconnected utterances. _Dysphrasia of Idiots._--Children have command at the beginning of no articulate sounds; then they learn these and syllables; after this also words of one syllable; then they speak short words of more than one syllable and sentences, but frequently babble forth words they have heard without understanding their meaning, like parrots. Imbeciles also frequently command only short words and sentences or monosyllabic words and sounds, or, finally, they lack all articulate sound. Many microcephalous idiots babble words without understanding their meaning, like little children. _Echo-speech or Echolalia_ (_Imitative Reflex Speech_).--Children not yet able to frame a sentence correctly like to repeat the last word of a sentence they have heard; and this, according to my observations and researches, is so general that I am forced to call this echolalia a physiological transition stage. Of long words said to them, the children usually repeat only the last two syllables or the last syllable only. The feeble-minded also repeat monotonously the words and sentences said by a person in their neighborhood without showing an awakened attention, and in general without connecting any idea with what they say. (Romberg.) _Interjectional Speech._--Children sometimes have a fancy for speaking in interjections. They express vague ideas by single vowels (like _ae_), syllables (e. g., _na_, _da_), and combinations of syllables, and frequently call out aloud through the house meaningless sounds and syllables. D and W are as yet undeveloped. Often, too, children imitate the interjections used by members of the family--_hop!_ _patsch_, _bauz!_ an interjectional echolalia. Many deranged persons express their feelings in like manner, in sounds, especially vowels, syllables, or sound-combinations resembling words, which are void of meaning or are associated merely with obscure ideas (Martini). Then D is connected with M only through L and S, and so through _i_ and _e_.
