Articulatory-defective children's discrimination of their production errors.

Discrimination and production performance of seven severely misarticulating children was analyzed in terms of errors in distinctive features and phonemes. Their performance on the McDonald Deep Test of Articulation and a minimal pairs discrimination test was also compared to the performance of children without articulation errors on the same measures. The normal children performed equally well in production and discrimination. However, the articulatory-error children performed poorly on the production test but performed almost as well as the normal children on the discrimination test. A discrepancy in articulatory-error children's production and discrimination of their error phonemes was obtained. They discriminated features and phonemes they did not produce. Clinical relevance of these findings are discussed.
