Non-word repetition and grammatical morphology: normative data for children in their final year of primary school.

It is likely that tests of phonological short-term memory (non-word repetition) and grammatical morphology (past tense, third-person singular) are clinical markers for specific language impairment (SLI). The study provides normative data on three specific tests covering the aforementioned areas for 100 children attending the final year of primary schooling (10-11 year olds). Data from typically developing age controls can be used to provide a benchmark against which to compare the ability of language-impaired children. This is particularly important given that the transition from primary to secondary schooling is a key stage in a child's education.
