Ja. Bowey et Mc. Debhal, SELECTIVELY PROMPTING SPEECH REPAIRS IN STAGE-I TO STAGE-V - A TECHNIQUE FOR INVESTIGATING EARLY METALINGUISTIC ABILITIES, Journal of psycholinguistic research, 23(3), 1994, pp. 267-275
When children aged from 1;6 to 3;6 made errors in relation to targeted
morphemes within grammatically obligatory contexts, a prompt of ''Par
don? '' was given. Morpheme repair rates increased with linguistic pro
ficiency, and with target morpheme mastery The selective use of prompt
ed repairs appears to be a useful technique for assessing rudimentary
abilities to monitor grammatical form within very young children.
