Criteria for identification of children as specifically language impaired (SLI) vary greatly among clinicians and researchers. Standardized psychometric discrepancy criteria are more restrictive and perhaps less sensitive to language impairment than is clinical judgment based on a child’s language performance in naturalistic contexts. This paper examines (a) differences in groups of preschool children clinically diagnosed as SLI who were and were not identified as SLI through standard psychometric discrepancy criteria, and (b) the validity of quantitative measures of mean length of utterance (MLU), syntax, and pragmatics derived from a spontaneous language sample as criteria for discriminating clinically diagnosed preschoolers from normally developing preschoolers. Spontaneous language data indicated that children clinically identified as SLI produced a significantly higher percentage of errors in spontaneous speech than normal children whether they met psychometric discrepancy criteria or not. Logistic regression analysis indicated that a combination of MLU, percent structural errors, and chronological age was the optimal subset of variables useful for predicting a clinical diagnosis of SLI. This combined criterion captured a larger proportion of the clinically identified SLI children than even the best psychometric discrepancy criteria.

A 3-year longitudinal study of the language performance of children from poverty was designed to address the problem of separating children with a specific language impairment (SLI) from low-scoring normal children in the borderline area on the continuum of language performance where normal ends and abnormal begins. Two approaches to definition were compared: an experimental approach (using story-retelling, rote-memory ability, and invented-morpheme learning) and a traditional approach (using standardized-test discrepancy scores). Results indicated that 6 of 34 children tracked from kindergarten through second grade appeared to be SLI at the end of the study. The best kindergarten predictor for the outcome status of these 6 children was a combination of the score on the Oral Vocabulary subtest of the TOLD-2P and the score on a combination of the experimental tasks. The best single kindergarten predictor of the academic status of the 15 children in the study who received academic remediation was story-retelling. Children’s scores on the experimental and standardized tests of language performance and nonverbal intelligence were profiled over the 3 years of the study, and patterns of change in many instances reveal the lifting of the early influences of poverty.

Spanish-speaking (SS) children with language impairment (LI) present with deficits in morphology and verb argument structure. These language areas may be useful for clinical identification of affected children. This study aimed to evaluate the discrimination accuracy of spontaneous language measures with SS preschoolers to tease out what combination of grammatical measure(s) were responsible for the LI deficits, and to determine the role of verb argument structure and syntactic complexity in identifying SS children with LI. Two sets of experiments were conducted on the spontaneous language samples of SS preschoolers with and without LI using discriminant function analyses. The study found that (a) mean length of utterance in words (MLUW) and ungrammaticality index in combination are fair to good discriminators of preschoolers with LI; (b) a morphology model combining correct use of articles, verbs, and clitics fairly discriminates LI children but may miss children whose language has limited syntactic complexity; and (c) semantic–syntactic complexity measures, such as MLUW, theme argument omissions, and ditransitive verb use, should be considered in the assessment of Spanish LI. The children who were bilingual and Spanish dominant in the study were classified as accurately as the Spanish-only children.

Similar Tendency

This study examined the characteristics of early lexical acquisition in children with specific language impairment. Sixteen unfamiliar words and referents were exposed across 10 sessions to language-impaired and normal children matched for level of linguistic development. Posttesting revealed similar comprehension-production gaps in the two groups of children. In addition, both groups showed greater comprehension and production of words referring to objects than words referring to actions. However, the language-impaired children's object word bias was not as marked as that of the normal children. For both groups, words containing initial consonants within the children's production repertoires were more likely to be acquired in production than words containing consonants absent from the children's phonologies. A similar tendency was not seen for comprehension.

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.

Many children are diagnosed as "specifically language-impaired" principally on the basis of their low scores relative to the norm on language measures. Yet it is often assumed that such children must suffer from a subtle disruption or defect in some peripheral or central mechanism that is involved in language learning. In this paper, an alternative view is offered: Many of these children may simply be limited in language ability in much the same way that others may be poor in musical, spatial, or bodily kinesthetic abilities.

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.

Several hypotheses have been offered to explain the grammatical morpheme difficulties observed in the speech of children with specific language impairment. Three of the accounts that could be evaluated in English were the focus of this study: the extended optional infinitive account, the implicit rule deficit account, and the surface account. Preschoolers with specific language impairment, a group of age controls, and a group of younger children matched for mean length of utterance were evaluated in their use of several theory-relevant grammatical morphemes. The findings revealed advantages for both the surface and extended optional infinitive hypotheses. In contrast, a test of the predictions based on the implicit rule deficit account suggested that the children studied here were not experiencing a deficit of this type.

Purpose Developmental language disorder (DLD), defined by low language performance despite otherwise normal development, can negatively impact children's social and academic outcomes. This study is the 1st to examine DLD in Vietnamese. To lay the foundation, we identified cases of DLD in Vietnam and explored language-specific characteristics of the disorder. Method Teacher ratings of 1,250 kindergarteners living in Hanoi, Vietnam, were used to recruit children with and without risk for DLD. One hundred four children completed direct measures of vocabulary and language sampling, and their parents completed in-depth surveys. We examined convergence and divergence across tasks to identify measures that could serve as reliable indicators of risk. Then, we compared performance on direct language measures across ability levels. Results There were positive associations between teacher and parent report and between report and direct language measures. Three groups were identified based on convergence across measures: DLD, some risk for DLD, and no risk. The DLD group performed lowest on measures of receptive and expressive vocabulary, mean length of utterance, and grammaticality. Although children with DLD exhibited a greater number of errors, the types of errors found were similar across DLD and No Risk groups. Conclusions Similar to rates found globally, 7% of the kindergarten population in Vietnam exhibited risk for DLD. Results highlight the importance of parent and teacher report and the value of multiple measures to identify DLD. We discuss potential clinical markers for DLD in the Vietnamese language and outline future directions.
