Features Of Language Impairment Research Articles

Language outcomes of children with cerebral palsy aged 5 years and 6years: a population-based study.

To examine the frequency, range, and features of language impairment in a community sample of children with cerebral palsy (CP) aged 5 to 6years. Children with CP born between 2005 and 2007 were identified through the Victorian Cerebral Palsy Register. Eighty-four participants were recruited, representing 48% of the contacted families. The recruited sample was representative of non-participants. Participants completed standardized measures of receptive and expressive language, and non-verbal cognition. Language impairment was identified in 61% (51/84) of participants. Twenty-four per cent (20/84) were non-verbal. Co-occurring receptive and expressive language impairment was common (37/84, 44%). Isolated receptive (6/84, 7%) and expressive (4/84, 5%) impairments occurred relatively infrequently. At a group level, verbal and non-verbal participants demonstrated deficits across language subdomains (i.e. semantics, syntax, morphology), rather than in single domains. Cognitive impairment and Gross Motor Function Classification System levels IV and V were associated with higher rates of language impairment (odds ratio [OR] 15.2, 95% confidence interval [CI] 3.2-71.8 and OR 8.5, 95% CI 1.8-40.3 respectively). Only cognition was independently associated with language impairment when both of these factors were considered within a multivariable model. Language impairment was common in 5-year-old and 6-year-old children with CP, affecting three out of five children. Participants were impaired across linguistic subdomains indicating a generalized language deficit. Findings suggest most children would benefit from a clinical language assessment. To target services effectively, subgroups of individuals with CP at greatest risk for language impairment need to be identified.

Dialectal grammatical differences in oral narratives of school-aged Indigenous Australian children

Purpose: Children's oral language samples are regularly analysed in order to describe levels of language development and develop learning goals. However, diagnostic interpretation of language samples from Indigenous Australian children is problematic due to overlap between features of Aboriginal English and features of language impairment in the mainstream non-Indigenous population. Limited studies explore the use of Aboriginal English and its diagnostic impact. This research, therefore, describes the grammatical features of language samples from one group of Indigenous Australian children.Method: Participants were 19 children aged 8;1–13;4 from the same school in a regional city with 100% Indigenous enrolment. The Test of Narrative Language was administered, eliciting three oral narratives, and features of Aboriginal English grammar were coded.Result: Dialect density was highly variable and greater in the Verb Phrase than in the Noun Phrase or Clause Structure. High teacher ratings of oral language ability aligned with lower measures of dialect density and higher grammatical accuracy for Standard Australian English. Grammatical accuracy was frequently higher for Aboriginal English than Standard Australian English.Conclusion: Over-identification of language impairment was identified as a risk when evaluating the language ability of Indigenous Australian children.
