To examine the role of different cognitive processes in accounting for the slower naming times of children with specific language impairment (SLI) relative to peers with no language impairment (NLI), three tasks designed to stress different types of processing were administered: naming pictures with the signal to respond presented at various delay intervals, naming following different durations of exposure to identical and unrelated primes, and vocally responding to nonlinguistic stimuli. Children with SLI, aged 4 to 9.5 years, were significantly slower than their NLI age peers on naming and on responding to nonlinguistic stimuli, but the effect of delay interval before naming and of duration of prime exposure before naming was similar for both groups. Results suggested that speed of naming is related to the slower nonlinguistic response processing of children with SLI and not to speed of their linguistic or perceptual processing. To examine differences in processing that might relate to pattern of language performance we examined responses of two subgroups of SLI. The subgroup of children whose language problems involved expressive but not receptive skills was not significantly slower than their NLI peers. The children whose problems involved both expressive and receptive language were significantly slower, but this was influenced by age. Findings are discussed in terms of language performance, age, task variables, and a generalized rate-limiting factor.

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.

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.

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.

Verb Inflections

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.

Purpose The goal of this study was to provide guidance to clinicians on early benchmarks of successful word learning in an interactive book reading treatment and to examine how encoding and memory evolution during treatment contribute to word learning outcomes by kindergarten children with specific language impairment (SLI). Method Twenty-seven kindergarten children with SLI participated in a preliminary clinical trial using interactive book reading to teach 30 new words. Word learning was assessed at 4 points during treatment through a picture naming test. Results The results indicate that the following performance during treatment was cause for concern, indicating a need to modify the treatment: naming 0–1 treated words correctly at Naming Test 1; naming 0–2 treated words correctly at Naming Test 2; naming 0–3 treated words correctly at Naming Test 3. In addition, the results showed that encoding was the primary limiting factor in word learning, but memory evolution also contributed (albeit to a lesser degree) to word learning success. Conclusion Case illustrations demonstrate how a clinician's understanding of a child's word learning strengths and weaknesses develop over the course of treatment, substantiating the importance of regular data collection and clinical decision-making to ensure the best possible outcomes for each individual child.

Mean Length Of Utterance

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.

The Impact

The impact of specific language impairment (SLI) on the acquisition of literacy and numeracy skills has been well researched. In contrast little has been written on its impact on the third core subject in the National Curriculum (NC) of science and this article describes a preliminary investigation into the scientific reasoning skills of children with SLI in comparison with those of typically developing (TD) children. In individual assessment sessions 11 pairs of target children with SLI and control TD children in the Key Stage (KS) 2 age span (ages 7–11 years) undertook a series of scientific reasoning tasks appropriate to their age involving receptive and expressive language skills. The children with SLI had for the most part significantly more difficulty with expressive language tasks (ELTs) than the TD children, in spite of the provision of scaffolding, and there was some evidence that they also had greater difficulty with the production of causal connectives, e.g. because, so. However, there was no difference between the two groups on receptive language tasks (RLTs) when scaffolding was used. Some possible implications for pedagogy are considered in light of these findings, and problems in matching children with SLI and TD controls are discussed.
