This study reports on the sensitivity of sentence repetition as a marker of specific language impairment (SLI) in different subgroups of children in middle childhood and examines the role of memory and grammatical knowledge in the performance of children with and without language difficulties on this task. Eleven year old children, 197 with a history of SLI and 75 typically developing (TD) peer...

We introduce a new approach that we call sequential linear interpolation (SLI) for approximating multidimensional nonlinear functions. The SLI is a partially separable grid structure that allows us to allocate more grid points to the regions where the function to be interpolated is more nonlinear. This approach reduces the mean squared error (MSE) between the original and approximated function ...

Audiovisual speech perception of children with specific language impairment (SLI) and children with typical language development (TLD) was compared in two experiments using /aCa/ syllables presented in the context of a masking release paradigm. Children had to repeat syllables presented in auditory alone, visual alone (speechreading), audiovisual congruent and incongruent (McGurk) conditions. S...

BACKGROUND Specific language impairment (SLI) is diagnosed when language is significantly below chronological age expectations in the absence of other developmental disorders, sensory impairments or global developmental delays. It has been suggested that gesture may enhance communication in children with SLI by providing an alternative means to convey words or extend utterances. However, gestur...

PURPOSE This study examined the types, frequencies, and distribution of speech disruptions in the spoken narratives of children with specific language impairment (SLI) and their age-matched (CA) and language-matched (LA) peers. METHOD Twenty 4th-grade children with SLI, 20 typically developing CA children, and 20 younger typically developing LA children were included in this study. Speech dis...

Sixteen children (17 age mates, 17 vocabulary mates) with specific language impairment (SLI) participated in two studies. In the first, they named fantasy objects. All groups coined novel noun-noun compounds on a majority of trials but only the SLI group had difficulty ordering the nouns as dictated by semantic context. In the second study, the children described the meaning of conventional nou...

This study investigated verbal working memory capacity in children with specific language impairment (SLI). The task employed in this study was the Competing Language Processing Task (CLPT) developed by Gaulin and Campbell (1994). A total of 40 school-age children participated in this investigation, including 20 with SLI and 20 normal language (NL) age-matched controls. Results indicated that t...

This study examines the comprehension and production of subject and object relative clauses (SRCs, ORCs) by children with Specific Language Impairment (SLI) and their typically developing (TD) peers. The purpose is to investigate whether relative clauses are problematic for Danish children with SLI and to compare errors with those produced by TD children. Eighteen children with SLI, eighteen TD...

Conversational indices of language impairment were used to investigate similarities and differences among children with Attention-Deficit/Hyperactivity Disorder (ADHD), children with Specific Language Impairment (SLI) and children with typical development (TD). Utterance formulation measures (per cent words mazed and average number of words per maze) differentiated the ADHD group from the SLI a...

Specific Language Impairment (SLI) is a heritable neurodevelopmental disorder diagnosed when a child has difficulties learning to produce and/or understand speech for no apparent reason (Bishop et al., 2012). The verbal difficulties of children with SLI have been largely documented, and a growing number of studies suggest that these children may also have difficulties in processing non-verbal c...
