This study examined the use of clitic pronouns by incipient bilingual Spanish-speaking 4- and 5-year-old children with and without language impairments. Incipient bilingualism refers to the initial stages of contact between two languages, when an individual still has only passive knowledge of a second language. The participants included 10 children with typical language development and 10 children with specific language impairment (SLI). The experimental task elicited clitic pronouns serving as direct objects with finite verbs (lo, la, los, and las). The children who had SLI used clitic pronouns less frequently than their age-matched peers and were less accurate in their use of gender agreement for clitics. No group differences were found for third person singular and plural verb inflections in the preterite tense. These results were compared to previous studies of Spanish- and Italian-speaking children with SLI.

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.

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.

The current study analysed article use in Spanish-speaking children with specific language impairment who are learning English as a second language. The SURFACE HYPOTHESIS account of specific language impairment was evaluated in relation to the use of articles in these children. Language samples were obtained from 15 Spanish-speaking children with language impairment and 15 with normal language, ages 5;0 to 7;1, matched by age, gender, and school. The percentage of article errors was tested between groups with a nonparametric analysis and an analysis of covariance with mean length of terminable unit as the covariate. Results revealed significant differences between groups on percent of article errors with and without MLTU as the covariate. Nonparametric statistics on percent of article error types indicated that most errors consisted of omissions and gender agreement substitutions. As predicted by the Surface Hypothesis, article errors were likely to occur in unstressed definite articles, suggesting that perceptual and prosodic processes have some impact on children's production of articles.

Target Article

The present investigation sought to evaluate patterns of article use in a group of monolingual Spanish-speaking children with specific language impairment (SLI). In particular, because of conflicting results reported in previous studies, it was of interest to discern specific types of nontarget responses and how these corresponded to what has been reported in other Spanish-speaking children with SLI. Eleven children with SLI and 11 age-matched peers participated in the study. Three different spontaneous speech samples were gathered from each child. In addition, an experimental task that assessed the children's use of articles with a variety of nouns was also administered to the children. The results of the study for both spontaneous speech and experimental data indicated that the children with SLI performed significantly poorer in their use of Spanish articles than their age-matched peers. Most of the nontarget responses consisted of omission of the target article. In contrast to a previous study by Restrepo and Gutiérrez–Clellen, the children did not present with deficits in noun phrase gender agreement. The gender errors that were observed appeared to be due to difficulties accessing the correct article form and not due to deficits in knowledge of the gender agreement paradigm. Possible theoretical explanations were explored suggesting that both processing and linguistic explanations, in particular optionality of determiners, could explain the observed patterns. Reasons for cross-study differences in error patterns are suggested, including relative phonological skill and language learning environment.

Mean Length Of Utterance

In earlier work, Italian-speaking children with specific language impairment (SLI) have been shown to exhibit a profile of grammatical morpheme difficulties that is quite different from the profile seen for English-speaking children with SLI. In the present study, this difference was confirmed using a wider range of grammatical morpheme types. A group of Italian-speaking children with SLI produced articles and third person plural verb inflections with lower percentages in obligatory contexts than a group of age controls and a group of younger controls matched for mean length of utterance (MLU). However, the children with SLI closely resembled the MLU controls in their production of noun plural inflections, third person copula forms, first person singular and plural verb inflections, and third person singular verb inflections. Errors on articles and copula forms were usually omissions whereas errors on verb inflections were usually productions of inappropriate finite inflections. Infinitives were seen in contexts requiring finite forms but they were not the dominant error type. Data from comprehension tasks raise the possibility that production factors were responsible for some of the differences seen. The findings of this study suggest that accounts of SLI are incomplete unless they assign a major role to the relative ease of identifying and interpreting the relevant data in the ambient language. The implications of these findings for current accounts of SLI are discussed.

And Function

Many English-speaking children with specific language impairment have unusual difficulty with grammatical morphemes such as past tense and third-person singular verb inflections and function words such as articles. Unfortunately, the source of this difficulty is not yet clear, in part because some of the possible contributing factors are confounded in English. In the present study, alternative accounts of grammatical morpheme difficulties were evaluated using children with specific language impairment who were acquiring Hebrew. We examined the grammatical morpheme production and comprehension of 15 Hebrew-speaking children with specific language impairment, 15 normally developing compatriots matched for age and 15 normally developing children matched for mean length of utterance in words. The results provided tentative support for the notion that grammatical morphemes are less difficult for children with specific language impairment if they take the form of stressed and/or lengthened syllables and if they appear in a language in which nouns, verbs, and adjectives must be inflected. The possibility that features such as person, number, and gender are missing from the underlying grammars of these children seems less likely.

Background and aims Impaired production of third person accusative pronominal clitics is a signature of language impairment in French-speaking children. It has been found to be a prominent and persistent difficulty in children and adolescents with specific language impairment. Previous studies have reported that many children with autism spectrum disorder also have low performance on these clitics. However, it remains unclear whether these difficulties in children with autism spectrum disorder are due to structural language impairment or to pragmatic deficits. This is because pragmatics skills, notoriously weak in children with autism spectrum disorder, are also needed for appropriate use of pronouns. Use of pronouns without clear referents and difficulty with discourse pronouns (first and second person), which require taking into account the point of view of one’s interlocutor (perspective shifting), have frequently been reported for autism spectrum disorder. Methods We elicited production of nominative, reflexive and accusative third and first person pronominal clitics in 19 verbal children with autism spectrum disorder (aged 6–12, high and low functioning, with structural language impairment, or with normal language) and 19 age-matched children with specific language impairment. If pragmatics is behind difficulties on these elements, performance on first-person clitics would be expected to be worse than performance on third person clitics, since it requires perspective shifting. Furthermore, worse performance for first person clitics was expected in the children with autism spectrum disorder compared to the children with specific language impairment, since weak pragmatics is an integral part of impairment in the former, but not in the latter. More generally, different error patterns would be expected in the two groups, if the source of difficulty with clitics is different (a pragmatic deficit vs. a structural language deficit). Results Similar patterns of relative difficulties were found in the autism spectrum disorder language impairment and specific language impairment groups, with third person accusative clitics being produced at lower rates than first-person pronouns and error patterns being essentially identical. First-person pronouns did not pose particular difficulties in the children with autism spectrum disorder (language impairment or normal language) with respect to third-person pronouns or to the children with specific language impairment. Performance was not related to nonverbal intelligence in the autism spectrum disorder group. Conclusions The elicitation task used in this study included explicit instruction, and focus on perspective shifting (both visual and verbal), allowing for potential pragmatic effects to be controlled. Moreover, the task elicited a variety of types of clitics in morphosyntactic contexts of varying complexity, providing ample opportunities for employment of perspective shifting, which may have also curtailed perseveration of third person over first person. These properties of the task allowed for the grammatical nature of children’s difficulties with third-person accusative clitics to emerge unambiguously. Implications Assessment of structural language abilities in children with autism spectrum disorder requires careful consideration of task demands. The influence of pragmatic abilities on structural language performance can be circumvented by making the pragmatic demands of the task explicit and salient. Filtering out this potential influence on structural language performance is fundamental to understanding language profiles in children with autism spectrum disorder and thus which children could benefit from which kinds of language intervention.

Over Time

Purpose The current study tested whether the difficulties of children with specific language impairment (SLI) in skill acquisition are related to learning processes that occur while practicing a new skill or to the passage of time between practice and later performance. Method The acquisition and retention of a new complex grapho-motor symbol were studied in 5-year-old children with SLI and peers matched for age and nonverbal IQ. The children practiced the production of the symbol for 4 consecutive days. Retention testing took place 10 days later. Results Children with SLI began each practice day slower than their peers but attained similar levels of performance by its end. Although they increased their performance speed within sessions more than their peers, they did not retain their learning as well between sessions. The loss in speed was largest in the 10-day retention interval. They were also less accurate, but accuracy differences decreased over time. Between-session group differences in speed could not fully be accounted for based on fine motor skills. Conclusions In spite of effective within-session learning, children with SLI did not retain the new skill well. The deficit may be attributed to task forgetting in the presence of delayed consolidation processes.

Causal Pathway

Purpose Early language and speech acquisition can be delayed in twin children, a twinning effect that diminishes between 4 and 6 years of age in a population-based sample. The purposes of this study were to examine how twinning effects influence the identification of children with language impairments at 4 and 6 years of age, comparing children with specific language impairment (SLI) and nonspecific language impairment (NLI); the likelihood that affectedness will be shared within monozygotic versus dizygotic twin pairs; and estimated levels of heritability for SLI and NLI. Twinning effects are predicted to result in elevated rates of language impairments in twins. Method The population-based twin sample included 1,354 children from 677 twin pairs, 214 monozygotic and 463 dizygotic, enrolled in a longitudinal study. Nine phenotypes from the same comprehensive direct behavioral assessment protocol were investigated at 4 and 6 years of age. Twinning effects were estimated for each phenotype at each age using structural equation models estimated via diagonally weighted least squares. Heritabilities were calculated for SLI and NLI. Results As predicted, the twinning effect increased the percentage of affected children in both groups across multiple language phenotypes, an effect that diminished with age yet was still not aligned to singleton age peers. Substantial heritability estimates replicated across language phenotypes and increased with age, even with the most lenient definition of affectedness, at −1 SD . Patterns of outcomes differed between SLI and NLI groups. Conclusions Nonverbal IQ is not on the same causal pathway as language impairments. Twinning effects on language acquisition affect classification of 4- and 6-year-old children as SLI and NLI, and heritability is most consistent in the SLI group. Clinical practice requires monitoring language acquisition of twins to avoid misdiagnosis when young or a missed diagnosis of language impairments at school entry.
