ABSTRACTChildren with specific language impairment (SLI) often show more limited use of grammatical morphology than younger, normally developing children matched according to mean length of utterance (MLU). However, within groups of children with SLI, individual differences are seen in grammatical morpheme use. In this study, we examined the role of weak syllable use in explaining some of these differences. Employing two different languages – English and Italian - children with SLI were placed into pairs. The children in each pair showed similar MLUs; however, one member of the pair showed a greater use of particular function words. In each of the pairs examined in both languages, the children with the greater use of function words also showed a greater use of weak syllables that did not immediately follow strong syllables. The weak syllable productions of children showing a more limited use of function words in each pair seemed to be dependent on a strong syllable-weak syllable production sequence. This sequence appeared to be operative across several prosodic levels, as defined within the framework of prosodic phonology. Because weak syllables that follow strong syllables usually have longer durations than those that precede strong syllables, the findings might have a perceptual basis. However, the results raise the possibility that limitations in prosody can restrict the degree of grammatical morpheme use by children with SLI.

Italian-speaking children with specific language impairment (SLI) were compared to a group of younger control children in their use of auxiliary verbs, pronominal clitics, infinitives, present tense verb inflections, and articles. Differences favoring the control children were found for those morphemes that required the production of nonfinal weak syllables. On other grammatical morphemes, the two groups did not differ. A relationship was seen between the use of morphemes requiring nonfinal weak syllables and the use of nonfinal weak syllables that had no morpheme status. The findings are considered from the perspective of both prosodic production limitations and limitations in input processing.

Mean Length Of Utterance

The purpose of the present study was to examine the grammatical morphology and sentence imitation performance of two different groups of children with language impairment and to compare their performance with that of children learning language typically. Expressive use of tense-bearing and non-tenserelated grammatical morphemes was explored. Children with specific language impairment (SLI), with Down syndrome (DS), and with typical language development (TL) were matched on mean length of utterance (MLU). Performance was compared primarily on composite measures of tense, tense inflections, and nontense morphemes, as well as on the Sentences subtest of the Wechsler Preschool and Primary Scale of Intelligence—Revised (WPPSI-R; D. Wechsler, 1989). Exploratory analyses were completed on a set of 11 individual grammatical morphemes as a follow-up to the principal analyses. As predicted, the children with SLI performed significantly more poorly than the children with TL on all three composite measures. In addition, the DS group exhibited significantly weaker performance than did the TL group on the tense inflections and non-tense morpheme composites. Although there were no statistically reliable differences between the SLI and DS groups on any morpheme measure, the groups were not comparably weak in their use of the regular past, -ed; the irregular third person singular morphemes (e.g., has, does); the present progressive, -ing; or the use of modals. The SLI and DS groups both performed more poorly than did the TL group on the sentence imitation task.

Several competing proposals have been offered to explain the grammatical difficulties experienced by children with specific language impairment (SLI). In this study, the grammatical abilities of Swedish-speaking children with SLI were examined for the purpose of evaluating these proposals and offering new findings that might be used in the development of alternative accounts. A group of preschoolers with SLI showed lower percentages of use of present tense copula forms and regular past tense inflections than normally developing peers matched for age and younger normally developing children matched for mean length of utterance (MLU). Word order errors, too, were more frequent in the speech of the children with SLI. However, these children performed as well as MLU-matched children in the use of present tense inflections and irregular past forms. In addition, the majority of their sentences containing word order errors showed appropriate use of verb morphology. None of the competing accounts of SLI could accommodate all of the findings. In particular, these accounts—or new alternatives —must develop provisions to explain both the earlier acquisition of present tense inflections than past tense inflections and word order errors that seem unrelated to verb morphology.

Purpose This study investigated the relationship between 2 components of memory—phonological short-term memory (pSTM) and working memory (WM)—and the control of relative clause constructions in children with specific language impairment (SLI). Method Children with SLI and 2 control groups—an age-matched and a younger group of children with typical development—repeated sentences, including relative clauses, representing 5 syntactic roles and 2 levels of matrix clause complexity. The Working Memory Test Battery for Children was administered. Results All 3 groups showed significant associations between pSTM and both types of matrix clause construction. For children with SLI, significant associations emerged between (a) WM and more complex matrix clause constructions, (b) WM and relative clauses including a range of syntactic roles, and (c) pSTM and the least difficult syntactic role. In contrast, the age-matched control group could repeat almost all syntactic roles without invoking the use of either memory component. Conclusions The role of pSTM and WM in the production of relative clauses by children with SLI is influenced by the degree of difficulty of the structure to be recalled. In therapy, the effect of WM limitations can be minimized by approaching each structure within the context of a simple matrix clause.

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.

Passe Compose

ABSTRACTThis study examines inflectional abilities in French-speaking children with specific language impairment (SLI) using a verb elicitation task. Eleven children with SLI and age-matched controls (37–52 months) participated in the experiment. We elicited the passé composé using eight regular and eight irregular high frequency verbs matched for age of acquisition. Children with SLI showed dissimilar productive verb inflection abilities to control children (even when comparing participants with similar verb vocabularies and mean length of utterance in words). Control children showed evidence of overregularization and sensitivity to morphological structure, whereas no such effects were observed in the SLI group. Error patterns observed in the SLI group demonstrate that, at this age, they cannot produce passé composé forms in elicitation tasks, even though some participants used them spontaneously. Either context by itself might therefore be insufficient to fully evaluate productive linguistic abilities in children with SLI.

Selected discourse behaviors of children with specific language impairment (SU) presenting expressive (E:SLI) or combined expressive-receptive deficits (E-R:SLI) were compared to each other and to chronological age-mates and younger mean length of utterance (MLU)-matched children with normal-language skills. The two SLI subgroups varied from each other on specific measures of tum-taking and cohesion. These findings imply the need for future normative work with SLI subgroups differing in receptive skill, and indicate that, in the interim, pragmatic research with this population will need to consider potential effects of receptive language status when interpreting variations in outcomes for discourse-based variables.
