Sentence imitation as a marker of SLI in Czech: disproportionate impairment of verbs and clitics.

Purpose: The authors examined sentence imitation as a potential clinical marker of specific language impairment (SLI) in Czech and its use to identify grammatical markers of SLI.

Method: Children with SLI and the age- and language-matched control groups (total N = 57) were presented with a sentence imitation task, a receptive vocabulary task, and digit span and nonword repetition tasks. Sentence imitations were scored for accuracy and error types.
