THE DISCOVERY OF THE CHILD
Let O stand for the ear; L for the group of motor organs used
for the words which make up language; £7 for the auditory centre
of speech; and M for the motor centre. The paths 0U"and ML
are peripheral, the first centripetal and the second centrifugal; the
path UM is an intercentral connecting tract.
The centre U9 in which are formed the auditory images of
words, may be subdivided into three, as indicated in the figure 2.
Sounds are realized at Su9 syllables at Si, and words at P.
That separate centres for sounds and syllables may be formed
is confirmed by the pathology of language, in which in certain
forms of centrosensory partial failure of speech the patients can
no longer pronounce anything more than sounds, or sounds and
Small children are at first particularly sensitive to the simple
sounds of language with which, especially with S, the mother
fondles and calls for their attention, whilst later on the child
is sensitive to syllables, with which also his mother caresses him,
saying, " ba, ba, puf, tuf".
Finally, the simple word which attracts the attention of the
child is generally a dissyllable.
