Risk markers for SLI: a study of young language-learning children.

چکیده
BACKGROUND Adequate assessment of 'normal variation' versus 'abnormal status' is particularly difficult for clinicians working with young children who are under 5 years of age and who present with slow language development. There is therefore clinical motivation to identify possible key difficulties (or 'risk markers') that may distinguish children who are likely to have specific language impairment (SLI) from the variation observed in younger, normally developing children. AIMS The issue of 'risk markers' for SLI was explored. It is well known that the issue of markers is controversial. The view presented here is that a risk marker represents a symptom with no assumption about whether the symptom reflects a single cause or that this symptom alone identifies the disorder. METHODS AND PROCEDURES The performance of 32 children with SLI was compared with that of 32 younger normal language-learning children on four potential risk marker tasks: non-word repetition, digit recall, past tense provision and plural marking. OUTCOMES AND RESULTS The findings suggest that processing markers, particularly non-word repetition, have the potential for indicating SLI risk. In particular, children who fall in the bottom quarter of the normal distribution in non-word repetition (performance below the 25th centile) appear to be at risk of SLI. CONCLUSIONS Although these results need to be interpreted cautiously, the evidence is thought to warrant the use of non-word repetition tasks in clinical practice.

Learning trajectories for speech motor performance in children with specific language impairment.
UNLABELLED Children with specific language impairment (SLI) often perform below expected levels, including on tests of motor skill and in learning tasks, particularly procedural learning. In this experiment we examined the possibility that children with SLI might also have a motor learning deficit. Twelve children with SLI and thirteen children with typical development (TD) produced complex non...

Introduction: Students with specific language impairment (SLI) have many difficulties in producing coherent written texts The goal of this study was to investigate and compare the management of cohesion in the written production of individuals with SLI and their normal peers in terms of density and diversity of connectives, the density of punctuation marks (periods and commas) and density and d...
متن کاملSpecific language impairment as a period of extended optional infinitive.
English-speaking children with specific language impairment (SLI) are known to have particular difficulty with the acquisition of grammatical morphemes that carry tense and agreement features, such as the past tense -ed and third-person singular present -s. In this study, an Extended Optional Infinitive (EOI) account of SLI is evaluated. In this account, -ed, -s, BE, and DO are regarded as fini...

This study tested the procedural deficit hypothesis of specific language impairment (SLI) by comparing children's performance in two motor procedural learning tasks and an implicit verbal sequence learning task. Participants were 7- to 11-year-old children with SLI (n = 48), typically developing age-matched children (n = 20) and younger typically developing children matched for receptive gramma...

This study re-explored the nature of verbal short-term memory (STM) deficits in children with specific language impairment (SLI), by distinguishing item and serial order STM processes. Recent studies have shown serial order STM capacity to be a critical determinant of language development, relative to item STM. In Experiment 1, 12 children with SLI, 12 age-matched children and 12 language-match...
