The purpose of this study was to evaluate children with specific language impairment (SLI) and their proficiency with the use of prepositions. Ten children with SLI were compared to 10 younger, normally developing children matched for mean length of utterance and 10 children matched for age. Each child was asked to produce 24 sentences containing locative (in, on) and dative (to) prepositions. Responses were coded for omission or word selection errors for the target prepositions. It was hypothesized that children with SLI would make more errors than the typically developing children. Omission errors would support a difficulty with syntax because of the role prepositions play in case marking. Word selection errors would support a deficit in the area of semantics. The results confirmed that children with SLI made more errors than the control group. The children with SLI made more errors in the selection of dative prepositions, indicating a difficulty linking the semantics of prepositions and verbs.

Mean Length Of Utterance

Spanish-speaking preschoolers with specific language impairment (SLI) were compared to typically developing same-age peers (TD-A) and younger typically developing children matched for mean length of utterance (TD-MLU) in terms of their use of grammatical morphology in spontaneous speech. The children with SLI showed high levels of accuracy on present tense and past tense (preterite) verb inflections. However, their use of definite articles and direct object clitics was significantly more problematic than for either the TD-MLU or the TD-A children. Substitutions and omissions were observed, especially in contexts requiring plural articles and clitics. Many of the details of the observed Spanish SLI profile were predicted by Wexler's (Extended) Unique Checking Constraint (EUCC) proposal. Remaining details in the data could be accommodated by making additional assumptions within the same general linguistic framework as the EUCC. Some of the differences between the findings from Spanish and those from previous studies on related languages such as Italian suggest the need for clinical assessment and intervention procedures that are shaped as much by language-specific details as by the language's typology.

Mean Length Of Utterance

The lexical diversity of children with specific language impairment (SLI) (ages 3 years 7 months to 7 years 3 months) was compared to that of normally developing same-age peers and younger normally developing children matched according to mean length of utterance in words (MLUw). Lexical diversity was calculated from spontaneous speech samples using D, a measure that uses repeated calculations of type-token ratio (TTR) to estimate how TTR changes as the speech samples increase in size. When D computations were based on 250-word samples, developmental differences were apparent. For both children with SLI and typically developing children, older subgroups showed higher D scores than younger subgroups, and subgroups with higher MLUws showed higher D scores than subgroups with lower MLUws. Children with SLI did not differ from same-age peers. At lower MLUw levels, children with SLI showed higher D scores than younger typically developing children matched for MLUw. The developmental sensitivity of D notwithstanding, comparisons using 100-utterance samples, in which the number of lexical tokens varied as a function of the children's MLUws, and comparisons between 250- and 500-word samples revealed the possible influence of sample size on this measure. However, analysis of the effect sizes using smaller and larger samples revealed that D is not affected by sample size to the degree seen for more traditional measures of lexical diversity.

Studies of children with specific language impairment (SLI) often include 2 comparison groups of typically developing children—a group matched according to age and a group matched according to mean length of utterance (MLU). In these studies, both groups of typically developing children often perform better than the SLI group. For many of these investigations, grammatical morpheme use constitutes the dependent measure. The use of grammatical morphemes requires longer utterances than the failure to use these morphemes. If children with SLI show less use of grammatical morphemes than typically developing children matched for MLU, shouldn't they produce some other detail of language more frequently than the MLU-matched group¿ In this article, the authors report 2 studies showing that such offsetting effects are not necessary in principle, given the nature of MLU. The implications of these findings are discussed.

The focus of this study was the use of grammatical morphology by Spanish-speaking preschoolers with specific language impairment (SLI). Relative to both same-age peers and younger typically developing children with similar mean lengths of utterance (MLUs), the children with SLI showed more limited use of several different grammatical morphemes. These limitations were most marked for noun-related morphemes such as adjective-agreement inflections and direct object clitics. Most errors on the part of children in all groups consisted of substitutions of a form that shared most but not all of the target’s grammatical features (e.g., correct tense and number but incorrect person). Number errors usually involved singular forms used in plural contexts; person errors usually involved third person forms used in first person contexts. The pattern of limitations of the children with SLI suggests that, for languages such as Spanish, additional factors might have to be considered in the search for clinical markers for this disorder. Implications for evaluation and treatment of language disorders in Spanish-speaking children are also discussed.

PurposeLipreading and its cognitive correlates were studied in school-age children with typical language development and delayed language development due to specific language impairment (SLI).MethodForty-two children with typical language development and 20 children with SLI were tested by using a word-level lipreading test and an extensive battery of standardized cognitive and linguistic tests.ResultsChildren with SLI were poorer lipreaders than their typically developing peers. Good phonological skills were associated with skilled lipreading in both typically developing children and in children with SLI. Lipreading was also found to correlate with several cognitive skills, for example, short-term memory capacity and verbal motor skills.ConclusionsSpeech processing deficits in SLI extend also to the perception of visual speech. Lipreading performance was associated with phonological skills. Poor lipreading in children with SLI may be, thus, related to problems in phonological processing.

Purpose This study examined sentence comprehension in children with specific language impairment (SLI) in a manner designed to separate the contribution of cognitive capacity from the effects of syntactic structure. Method Nineteen children with SLI, 19 typically developing children matched for age (TD-A), and 19 younger typically developing children (TD-Y) matched according to sentence comprehension test scores responded to sentence comprehension items that varied in either length or their demands on cognitive capacity, based on the nature of the foils competing with the target picture. Results The TD-A children were accurate across all item types. The SLI and TD-Y groups were less accurate than the TD-A group on items with greater length and, especially, on items with the greatest demands on cognitive capacity. The types of errors were consistent with failure to retain details of the sentence apart from syntactic structure. Conclusions The difficulty in the more demanding conditions seemed attributable to interference. Specifically, the children with SLI and the TD-Y children appeared to have difficulty retaining details of the target sentence when the information reflected in the foils closely resembled the information in the target sentence.

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.

Discriminant function analysis was employed to determine if grammatical morpheme production could be used to classify preschool-age children with specific language impairment (SLI) and children with typically developing language skills. Three variables were included in the discriminant analysis: a finite verb morpheme composite, a noun morpheme composite, and mean length of utterance in morphemes. The children with SLI and age-matched controls were discriminated with high levels of accuracy, though the three variables did not yield identical classifications. Across two samples of typically developing children and children with SLI, the verb morpheme composite showed sensitivity exceeding 85% and specificity of 100%. In light of these results and growing evidence that problems with finite verb morphology continue into the school years in children with SLI, the verb morpheme composite was considered to hold promise as a clinical marker for SLI.
