As this impulsive articulation develops it becomes complicated by a distinctly intentional element. The child hears the sounds he produces and falls in love with them. From this moment he begins to go on babbling for the pleasure it brings. We see the germ of such a pleasure-seeking babbling in the protracted iterations of the same sound. The first reduplications and serial iterations, _a-a_, _ma-ma_, etc., may be due to physiological inertia, the mere tendency to move along any track that happens to be struck, the very same tendency which makes a prosy speaker go on repeating himself. At the same time there is without doubt in these infantile iterations a rudiment of self-imitation. That is to say, the child having produced a sound, as _na_ or _am_, impulsively proceeds to repeat the performance in order to obtain a renewal of the sound-effect. This renewed impulse may be supposed further to bring with it a germ of the pleasure of iteration of sound, or assonance. The addition of a simple rhythmic character to the series of sounds is a further indication of its pleasure-seeking character. Indeed we have in this infantile ‘la-la-ing’ more a rudiment of song and music than of articulate speech. The rude vocal music of savages consists of a similar rhythmic threading of meaningless sounds in which as in this infantile song changes of feeling reflect themselves. We may best describe this infantile babbling then as voice-play and as rude spontaneous singing, the utterance of a mood, indulged in for the sake of its own delight, and serving by a happy arrangement of nature as a preliminary practice in the production of articulate or linguistic sounds. _Transition to Articulate Speech._ Let us now seek to understand how this undesigned trying of the articulate instrument passes into true significant articulation, how this speech-protoplasm develops into the organism that we call language. And here the question at once arises: Does the child tend to utilise the sounds thus acquired as signs apart from the influence of education, that is to say, of the articulate sounds produced by others and impressed as signs upon his attention? The question is not easy to answer owing to the early development of the imitative impulse and to the constant and all-pervading influence of education in the nursery. Yet I will offer a tentative answer.
