scholarly journals Do nonword repetition errors in children with specific language impairment reflect a weakness in an unidentified skill specific to nonword repetition or a deficit in simultaneous processing?

Double Deficit

This Commentary supports Gathercole's (2006) proposal on a double deficit in children with specific language impairment (SLI). The author suggests that these children have a limited phonological storage combined with a particular problem of processing novel speech stimuli. According to Gathercole, there are three areas of skill contributing to memory for nonwords: general cognitive abilities, phonological storage, and an unidentified skill specific to nonword repetition. The focus of this Commentary is to examine whether these children's nonword repetition performance is influenced by an unidentified skill or some other processes. An alternative hypothesis is that the nonword repetition errors observed in children with SLI are related to one of their main weaknesses, to their difficulties in simultaneous processing of information. Evidence for this argument comes from our recent studies: from error analyses data and from findings on nonword repetition with stimuli that included meaningful parts (monosyllabic real words).

Purpose: The purpose of this study was to determine whether specific language impairment (SLI) and dyslexia are distinct developmental disorders. Method: Study 1 investigated the overlap between SLI identified in kindergarten and dyslexia identified in 2nd, 4th, or 8th grades in a representative sample of 527 children. Study 2 examined phonological processing in a subsample of participants, including 21 children with dyslexia only, 43 children with SLI only, 18 children with SLI and dyslexia, and 165 children with typical language/reading development. Measures of phonological awareness and nonword repetition were considered. Results: Study 1 showed limited but statistically significant overlap between SLI and dyslexia. Study 2 found that children with dyslexia or a combination of dyslexia and SLI performed significantly less well on measures of phonological processing than did children with SLI only and those with typical development. Children with SLI only showed only mild deficits in phonological processing compared with typical children. Conclusions: These results support the view that SLI and dyslexia are distinct but potentially comorbid developmental language disorders. A deficit in phonological processing is closely associated with dyslexia but not with SLI when it occurs in the absence of dyslexia.

Repetition Task

In this study, the authors compare the production of internal codas and branching onsets in four groups of children learning French: monolingual typically-developing children ( n = 12), bilingual typically-developing children ( n = 61), monolingual children with Specific Language Impairment ( n = 17) and bilingual children with Specific Language Impairment ( n = 20). Their elicited productions were collected using a nonword repetition task (LITMUS-NWR-French), containing 71 nonwords with different syllable types. Except for typically-developing monolingual children, all children performed significantly better on branching onsets than on internal codas. Moreover, the repair strategies used in erroneous productions also indicate that children had more difficulties with internal codas: all the cases of metathesis affecting a target internal coda resulted in the production of a branching onset whereas the contrary was not observed. The differences in the rates of target-like production and the patterns of metathesis of these two structures suggest that internal codas are more difficult than branching onsets for children learning French.

Performance Profiles

Many English-speaking children with specific language impairment have been found to be especially weak in their use of grammatical morphology. In a separate literature, many children meeting the same subject description have shown significant limitations on tasks involving the perception of rapid acoustic changes. In this study, we attempted to determine whether there were parallels between the grammatical morphological limitations of children with specific language impairment and their performance profiles across several perceptual contrasts. Because most English grammatical morphemes have shorter durations relative to adjacent morphemes in the speech stream, we hypothesized that children with specific language impairment would be especially weak in discriminating speech stimuli whose contrastive portions had shorter durations than the noncontrastive portions. Results from a group of eight children with specific language impairment with documented morphological difficulties confirmed these predictions. Several possible accounts of the observed morphology-perception parallels are offered.

Syntactic Development

In this paper, the issue of language impairment is set in a broader perspective of individual differences. Two aspects of language development are identified in which the discrepancies between domains of language and/or cognitive development often observed in specific language impairment (SLI) children occur naturally as a consequence of individual variation in rate of development together with relative independence of specific domains. In the first case, concerning bound morphemes versus syntactic development, research with precocious children complements data from language-impaired children in demonstrating that morphology is the component of language most tied to general language learning ability. In the second case, the definition of specific language impairment as a distinct etiology on the basis of discrepancy between language and nonverbal cognitive development (the "Cognitive Hypothesis") is shown to lead to an invalid prediction. Children with SLI do not show a distinctive response to language intervention, relative to children with even profiles of language and nonverbal cognitive abilities.
