Inner speech as a learned skill

Three experiments are reported which address the problem of defining a role for inner speech. Experiments 1 and 2 establish that inner speech is acquired by normally developing readers between the ages of 8 and 11, and that both slow and fast readers show a similar pattern of acquistition, but do so at a different rate from normal readers. We suggest that the development of inner speech accompanies a strategy of reading aloud “with expression”; and that it is a manifestation of the need to prestructure oral utterances. These will thus contain the lexical items visible on the page within an appropriate prosodic envelope. Both segmental and suprasegmental phonemes contribute to meaning of spoken and, by analogy, written language. Experiment 3 showed that children at this critical point in learning to read comprehended text better when certain prosodic features were made visible on the text. Prosodic restructureing may thus be an important skill acquired by young readers as they progress toward fluent, silent adult reading.
