ABSTRACTTwenty-five children with specific language impairment (SLI; age 5 years, 3 months [5;3]–8;2), 50 typically developing children (3;3–8;2), and 31 normal adults participated in three eye-tracking experiments of spoken language comprehension that were designed to investigate the use of verb information during real-time sentence comprehension in Spanish. In Experiment 1, participants heard sentences like El niño recorta con cuidado el papel (The boy trims carefully the paper) in the presence of four depicted objects, only one of which satisfied the semantic restrictions of the verb recorta (e.g., paper, clock, fox, and dinosaur). Eye movements revealed that children with SLI, like other groups, were able to recognize and retrieve the meaning of the verb rapidly enough to anticipate the upcoming semantically appropriate referent, prior to actually hearing the noun phrase el papel (the paper). Experiments 2 and 3 revealed that for all groups of participants, anticipatory eye movements were also modulated by the semantic fit of the object serving as the patient/theme of the verb. Relatively fine-grained semantic information of a verb was computed fast enough even by children with SLI to result in anticipatory eye movements to semantically appropriate referents. Children with SLI did differ from age-matched controls, but only slightly in terms of overall anticipatory looking at target objects; the time course of looking between these groups was quite similar. In addition, no differences were found between children with SLI and control children matched for mean length of utterance. Implications for theories that characterize SLI are discussed.

Processing Task

In this study we examined the influence of working memory on the off-line and real-time sentence comprehension/processing of children with specific language impairment (SLI). A total of 12 children with SLI, 12 normally developing children matched for chronological age (CA), and 12 children matched for receptive syntax (RS) completed three tasks. In the working memory task, children recalled as many words as possible under three processing load conditions varying in the number of mental operations (i.e., no load, single load, dual load). In the off-line comprehension task, children listened to linguistically nonredundant and redundant sentences. In the real-time sentence processing task, children monitored sentences for the occurrence of a target word appearing at the beginning, middle, or end of a test sentence and pushed a response pad as quickly as possible upon hearing the target. In the memory task, SLI children recalled fewer words in the dual-load condition relative to CA peers, who showed no condition effect. The SLI and RS groups performed similarly overall; however, both groups recalled fewer words in the dual-load condition than in the other conditions. In the off-line task, the SLI group comprehended fewer sentences of both types relative to the CA controls and fewer redundant sentences relative to themselves and to the RS controls. A significant correlation between working memory and sentence comprehension was found for the SLI group and control groups. For the on-line task, between-group analyses revealed that the SLI group yielded an overall slower word recognition reaction time than the CA and RS groups. Working memory and sentence processing were not correlated for any group. Results were interpreted to suggest that SLI children have a more limited functional working memory capacity than their CA peers. Children with SLI also appear to have greater difficulty managing their working memory resources relative to both age peers and younger children when performing a conventional off-line sentence comprehension task but not a real-time sentence processing task.

Purpose Given the complexity of sentence processing and the specific problems that children with specific language impairment (SLI) experience, we investigated the time course and characteristics of semantic processing at the sentence level in Dutch preschoolers with SLI. Method We measured N400 responses to semantically congruent and incongruent spoken sentences (e.g., “My father is eating an apple/*blanket”) in a group of 37 Dutch preschoolers with SLI and in a group of 25 typically developing (TD) peers. We compared the time course and amplitude of the N400 effect between the two groups. Results The TD group showed a strong posterior N400 effect in time windows 300–500 ms and 500–800 ms. In contrast, the SLI group demonstrated only a reliable N400 effect in the later time window, 500–800 ms, and did not show a stronger presence at posterior electrodes. Conclusion The findings suggest that the neuronal processing of semantic information at sentence level is atypical in preschoolers with SLI compared with TD children.

Rate Interaction

Purpose Decay of memory traces is an important component of many theories of working memory, but there is conflicting evidence on whether the rate of decay differs for individuals with specific language impairment (SLI) as compared to peers with typical language. The authors tested the hypothesis that adults with SLI have a slower decay rate. Method Twenty adults with SLI, ages 18–27 years, and 23 age-matched peers identified target words in sentences. Sentences were presented at normal and slow rates. Participants separately judged whether a picture and sentence matched in meaning as a measure of sentence processing efficiency. Results After controlling for sentence processing efficiency, the group with SLI was slower to detect words in sentences. Response times for the group with SLI increased less in the slow condition as compared to the group with typical language, resulting in a Group × Presentation Rate interaction. Conclusions The Group × Presentation Rate interaction is consistent with a slower lexical decay rate for adults with SLI, but differences in the ability to manage interference could not be ruled out. The findings suggest that decay rate differences may play a role in the working memory limitations found in individuals with SLI.

Purpose This study examined sentence comprehension in children with specific language impairment (SLI) in a manner designed to separate the contribution of cognitive capacity from the effects of syntactic structure. Method Nineteen children with SLI, 19 typically developing children matched for age (TD-A), and 19 younger typically developing children (TD-Y) matched according to sentence comprehension test scores responded to sentence comprehension items that varied in either length or their demands on cognitive capacity, based on the nature of the foils competing with the target picture. Results The TD-A children were accurate across all item types. The SLI and TD-Y groups were less accurate than the TD-A group on items with greater length and, especially, on items with the greatest demands on cognitive capacity. The types of errors were consistent with failure to retain details of the sentence apart from syntactic structure. Conclusions The difficulty in the more demanding conditions seemed attributable to interference. Specifically, the children with SLI and the TD-Y children appeared to have difficulty retaining details of the target sentence when the information reflected in the foils closely resembled the information in the target sentence.

ABSTRACTThis study investigates whether number dissimilarities on subject and object DPs facilitate the comprehension of subject- and object-extracted centre-embedded relative clauses in children with Grammatical Specific Language Impairment (G-SLI). We compared the performance of a group of English-speaking children with G-SLI (mean age: 12;11) with that of two groups of younger typically developing (TD) children, matched on grammar and receptive vocabulary, respectively. All groups were more accurate on subject-extracted relative clauses than object-extracted ones and, crucially, they all showed greater accuracy for sentences with dissimilar number features (i.e., one singular, one plural) on the head noun and the embedded DP. These findings are interpreted in the light of current psycholinguistic models of sentence comprehension in TD children and provide further insight into the linguistic nature of G-SLI.

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.
