Vocate: written and inner speech

the functional and structural features of written speech . . . have . . . one important aspect; they inevitably lead to a considerable development of inner speech. Delaying the direct revelation of speech connections, inhibiting them and showing increased requirements for the preliminary speech act not being revealed at once by training, written speech produces such a rich development of inner speech as could not have a place in the earlier phases of development. Therefore, neuropathologists are not working at random when, desiring to investigate the possibilities of inner speech, they turn to the nature of the written speech of their patients.
