Sound-based language play in four language-impaired subjects

The production of sound-based language play in four language-impaired subjects was investigated. A battery of metalinguistic tests, incorporating the production of poems, nursery rhymes, alliteration and rhyme, was designed to assess the subjects' sound-based language play. The subjects' performance on these tests was compared with their performance on a battery of standardised language tests. Results indicated that the language-impaired subjects did not successfully involve themselves in sound-based language play. Furthermore, a decrease in sound-based language play was observed with an increase in the extent of the language impairment. Hence, a positive correlation was found between poor language competence and deficient metalinguistic skills. Diagnostic, therapeutic and theoretical implications are discussed.
