Semantic Distinction

Purpose The purpose of this study was to delineate differences between children with specific language impairment (SLI), typical age–matched (TAM) children, and typical younger (TY) children in learning and mastering an undisclosed artificial morphological rule (AMR) through exposure and usage. Method Twenty-six participants (eight 10-year-old children with SLI, 8 TAM children, and ten 8-year-old TY children) were trained to master an AMR across multiple training sessions. The AMR required a phonological transformation of verbs depending on a semantic distinction: whether the preceding noun was animate or inanimate. All participants practiced the application of the AMR to repeated and new (generalization) items, via judgment and production tasks. Results The children with SLI derived significantly less benefit from practice than their peers in learning most aspects of the AMR, even exhibiting smaller gains compared to the TY group in some aspects. Children with SLI benefited less than TAM and even TY children from training to judge and produce repeated items of the AMR. Nevertheless, despite a significant disadvantage in baseline performance, the rate at which they mastered the task-specific phonological regularities was as robust as that of their peers. On the other hand, like 8-year-olds, only half of the SLI group succeeded in uncovering the nature of the AMR and, consequently, in generalizing it to new items. Conclusions Children with SLI were able to learn language aspects that rely on implicit, procedural learning, but experienced difficulties in learning aspects that relied on the explicit uncovering of the semantic principle of the AMR. The results suggest that some of the difficulties experienced by children with SLI when learning a complex language regularity cannot be accounted for by a broad, language-related, procedural memory disability. Rather, a deficit—perhaps a developmental delay in the ability to recruit and solve language problems and establish explicit knowledge regarding a language task—can better explain their difficulties in language learning.

The present study investigated whether children with specific language impairment (SLI) differed from children with normal language learning in their ability to process binaural temporal information. The SLI group was matched with peers of the same chronological age, as well as peers with similar language age. All three subject groups were tested with measures of complex sound localization involving the precedence effect phenomenon. Subjects were required to track the apparent motion of a “moving” fused auditory image (FAI). Movement of the FAI was simulated by varying the delay incrementally between pairs of clicks presented, one each, from two matched loudspeakers placed on opposite sides of the child’s head. With this task, the SLI subjects’ performances were found to be similar to their language age-matched but chronologically younger peers. Both groups exhibited tracking skills that were statistically poorer than that of the chronologically age-matched group. Additional tests indicated this effect was not due to differences in motoric tracking abilities nor to the SLI subjects’ abilities to perceive small binaural time cues. Thus, children with SLI appear to be impaired in their ability to use binaural acoustic information in a dynamic ongoing fashion. The requirements for processing such nonlinguistic acoustic information in a “dynamic and ongoing” fashion may be similar to those involved in the ongoing processing of rapid changes in the temporal and spectral components of the speech chain.

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.

To examine patterns that might suggest etiologic subgroups of specific language impairment (SLI), information, including history of speech-language-learning (SLLD) problems in family members, was obtained on 53 children with SLI aged 4 to 9½ years. The results led to the generation of a number of hypotheses for future research. In particular, the findings suggested that family history is related to pattern of language performance. In comparison with children who had both expressive and receptive language deficits, children with deficits in only expressive language had a higher proportion of affected family members (.47 vs. .22), of affected mothers (.57 vs. .17), and of affected siblings (.53 vs. .27). These and other findings are discussed in terms of their consistency with other data, hypotheses relative to explanations of SLI, and their implications for further research.

Matched Samples

The aim of the present study was to use longitudinal data to provide a detailed profile of early word combinations by children with SLI. Three children with SLI were videotaped during mother-child interactions in the home over a 2-year period. The data obtained were compared to MLU-matched samples of normal language-learning children from Wells’ (1981) longitudinal database, which provided a control for the linguistic measures used in this study. A range of analyses were carried out on controlled data samples in order to determine how the children with SLI’s early utterances compared with those of MLU-matched normal language peers. The measures were specifically designed to assess the children’s use of verbs and verb morphology because recent research has suggested that verbs may play a central role in the acquisition process, and children with SLI may have particular problems with verbs. We found that children with SLI used verbs less frequently, nouns more frequently, and were more input-dependent than their MLU-matched peers. The children with SLI used verb bare stems incorrectly more often than their MLU-matched counterparts. However, further analyses showed that this high frequency of incorrect bare stems may be at least partly due to the fact that children with SLI have particular difficulties using auxiliaries. Furthermore, the proportion of verb use that consisted of General All Purpose (GAP) verbs for children with SLI was similar to that of the MLU-matched children. The above findings were compared with those from other relevant studies of lexical diversity in children with SLI, and the potential implications of these data for theories of SLI language development were discussed, particularly with reference to Marchman and Bates’ (1994) "critical mass" hypothesis.

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.

Comprehensive Intervention

Although they often have significant difficulties in other areas, most children with specific language impairment (SLI) have special difficulties with the understanding and use of grammar. Therefore, most of these children will require an intervention program that targets comprehension or production of grammatical form. Language interventionists are faced with the difficult task of developing comprehensive intervention programs that address the children's grammatical deficits while remaining sensitive to their other existing and predictable social, behavioral, and academic problems. The purpose of this article is to present and justify 10 principles that we regard as essential for planning adequate interventions for children with language-learning problems. These principles are relevant for all children with problems in the use of grammar, but they are especially appropriate for 3- to 8-year-old children with SLI. Although all of our examples are from English, the principles we have chosen are sufficiently broad to cut across many linguistic and cultural boundaries.

The Keynote Article is a very welcomed, timely, and incisive review article that examines theoretical and clinical implications of research on bilingual development and specific language impairment (SLI). Paradis provides a considered examination of the available evidence and takes into account a number of potential influencing factors. In particular, I want to commend her discussion of potential compensatory mechanisms that may play a role in bilingual development in SLI. This is often a neglected area in discussions concerning SLI. I also want to highlight that I agree wholeheartedly with her conclusion that the evidence to date “leans toward a positive attitude toward dual language learning for children with SLI who are in a supportive context for bilingualism.” This message is by no means universally accepted, nor is it put into action in therapeutic contexts across the United Kingdom and Europe. There is still much debate as to what type of advice should be given to parents and what the target language or languages of therapy should be (Harulow, 2008). This review article has therefore the potential not only to make a significant contribution to theory but also to practice.

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.
