This study is concerned with characteristics of short-term memory (STM) in children with specific language impairment (SLI). The linguistic requirements of the test procedure, the characteristics of the test materials, and the development of linguistic representations were considered. Two experimental tasks were used: a verbal-repetition and a picture-pointing procedure. The tasks used auditory presentation and were designed to explore different underlying processes during immediate recall. The linguistic characteristics of the test materials were designed to explore the influence of semantic, lexical, and phonological factors on STM. Six SLI children (aged 6:1 to 9:6) (years:months) were individually matched on comprehension and expression of language to 17 younger children (age 3:4 to 6:5). Both groups were differentially influenced by the materials as a function of the test procedure. In general, both group and individual analyses found no significant difference between the performance of the SLI children and language-age (LA) controls. The implications of the results in relation to previous findings from investigations of STM and the underlying cause of SLI in children are discussed.

Audiovisual Stimuli

School-age children with specific language impairment (SLI) and age-matched controls were tested for immediate recall of digits presented visually, auditorily, or audiovisually. Recall tasks compared speaking and pointing response modalities. Each participant was tested at a level that was consistent with her or his auditory short-term memory span. Traditional effects of primacy, recency, and modality (an auditory recall advantage) were obtained for both groups. The groups performed similarly when audiovisual stimuli were paired with a spoken response, but children with SLI had smaller recency effects together with an unusually poor recall when visually presented items were paired with a pointing response. Such results cannot be explained on the basis of an auditory or speech deficit per se, and suggest that children with SLI have difficulty either retaining or using phonological codes, or both, during tasks that require multiple mental operations. Capacity limitations, involving the rapid decay of phonological representations and/or performance limitations related to the use of less demanding and less effective coding and retrieval strategies, could have contributed to the working memory deficiencies in the children with SLI.

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.

Cognitive Correlates

PurposeLipreading and its cognitive correlates were studied in school-age children with typical language development and delayed language development due to specific language impairment (SLI).MethodForty-two children with typical language development and 20 children with SLI were tested by using a word-level lipreading test and an extensive battery of standardized cognitive and linguistic tests.ResultsChildren with SLI were poorer lipreaders than their typically developing peers. Good phonological skills were associated with skilled lipreading in both typically developing children and in children with SLI. Lipreading was also found to correlate with several cognitive skills, for example, short-term memory capacity and verbal motor skills.ConclusionsSpeech processing deficits in SLI extend also to the perception of visual speech. Lipreading performance was associated with phonological skills. Poor lipreading in children with SLI may be, thus, related to problems in phonological processing.

Interference Study

ABSTRACTIn picture naming, semantic context words produce either facilitation or inhibition, depending on their relationship to the target-picture name. This study used the picture–word interference task to examine facilitative effects of associates (the word carrot paired with a picture of rabbit) and inhibitory effects of coordinates (mouse paired with a rabbit) in children and adults. Experiment 1 with adults (N = 44) documented robust associate and coordinate effects with either auditory or visual presentation of interfering words. Experiment 2 used auditory presentation of interfering words with children (N = 44, 6 years, 10 months to 11 years, half with typical development, half with specific language impairment). Children showed significant facilitation from associates but no reliable coordinate interference effect. The strength of the associative priming effect in children was correlated with their language abilities (Peabody Picture Vocabulary Test and Clinical Evaluation of Language Fundamentals scores). The results indicate the dominant role of association in facilitating word retrieval in speech production in children. In children with specific language impairment, lexical access gains weaker support from networks of associations in semantic memory.
