Finally it is the simple word, dissyllabic in most cases, which attracts the child's attention.

But for the motor centres also the same thing may be repeated; the child utters at the beginning simple or double sounds, as for example bl, gl, ch, an expression which the mother greets with joy; then distinctly syllabic sounds begin to manifest themselves in the child: ga, ba; and, finally, the dissyllabic word, usually labial: mama.

We say that the spoken language begins with the child when the word pronounced by him signifies an idea; when for example, seeing his mother and recognising her he says "mamma;" and seeing a dog says, "tettè;" and wishing to eat says: "pappa."

Thus we consider language begun when it is established in relation to perception; while the language itself is still, in its psycho-motor mechanism, perfectly rudimentary.

That is, when above the diastaltic arc where the mechanical formation of the language is still unconscious, the recognition of the word takes place, that is, the word is perceived and associated with the object which it represents, language is considered to have begun.

On this level, later, language continues the process of perfecting in proportion as the hearing perceives better the component sounds of the words and the psycho-motor channels become more permeable to articulation.

This is the first stage of spoken language, which has its own beginning and its own development, leading, through the perceptions, to the perfecting of the primordial mechanism of the language itself; and at this stage precisely is established what we call articulate language, which will later be the means which the adult will have at his disposal to express his own thoughts, and which the adult will have great difficulty in perfecting or correcting when it has once been established: in fact a high stage of culture sometimes accompanies an imperfect articulate language which prevents the æsthetic expression of one's thought.

The development of articulate language takes place in the period between the age of two and the age of seven: the age of perceptions in which the attention of the child is spontaneously turned towards external objects, and the memory is particularly tenacious. It is the age also of motility in which all the psycho-motor channels are becoming permeable and the muscular mechanisms establish themselves. In this period of life by the mysterious bond between the auditory channel and the motor channel of the spoken language it would seem that the auditory perceptions have the direct power of provoking the complicated movements of articulate speech which develop instinctively after such stimuli as if awaking from the slumber of heredity. It is well known that it is only at this age that it is possible to acquire all the characteristic modulations of a language which it would be vain to attempt to establish later. The mother tongue alone is well pronounced because it was established in the period of childhood; and the adult who learns to speak a new language must bring to it the imperfections characteristic of the foreigner's speech: only children who under the age of seven years learn several languages at the same time can receive and reproduce all the characteristic mannerisms of accent and pronunciation.
