Language impairment (LI) in school-age children is less explored than in younger children, particularly in languages other than English. Emergentist theorists emphasize effects of frequency of words and morpho-syntactic patterns (token/type frequency) on language processing. No studies have investigated frequency effects in morpho-syntactic error detection or correction, which are common measures of metalinguistic awareness. Aims: 1) Contribute to knowledge about LI in Swedish-speaking school-age children, 2) Investigate effects of frequency on error detection/correction, and 3) Discuss the metalinguistic demands of these tasks. Ten-year-olds with LI or typical development (TD) participated in error detection (NLI=10, NTD=30) and correction (nLI=8, NTD=30). TD children also participated in error repetition (control experiment, n=29). Sentences were presented in headphones. Target sentences contained errors that characterize the expressive language of Swedish pre-school children with LI: the infinitive instead of past-tense for regular/irregular verbs, and the omission of the indefinite article in common/neuter gender noun phrases (NPs). Target verbs and nouns were of either high or low frequency (HF/LF). Children with LI had weaker detection and correction results than TD children. Error detection results showed an error type by group interaction, indicating that children with LI had specific residual processing difficulties of the target structures compared to a singular/plural control error. Both groups were affected by frequency: LF verbs were associated with fewer detected and corrected errors, and more accurate repetitions compared to HF verbs. Errors involving irregular verbs were more difficult to correct (but not to detect) than those involving regular verbs. There were no effects of noun frequency on accuracy, but neuter NPs (with lower type frequency) were associated with fewer detected errors compared to common NPs. NP errors were easier to correct than to detect for both groups. The results indicated that error detection involves less explicit metalinguistic awareness than error correction and repetition. For correction, LF words and past-tense errors seem to demand more explicit awareness than HF words and NP errors. The results may help explain the variability often seen in the morpho-syntactic performance of children with LI. Effects of frequency are important to consider when assessing grammatical/metalinguistic ability.
