Severity of specific language impairment predicts delayed development in number skills
No full textThe extent to which mathematical development is dependent upon language is controversial. This longitudinal study investigates the role of language ability in children's development of number skills. Participants were 229 children with specific language impairment (SLI) who were assessed initially at age 7 and again 1 year later. All participants completed measures of psycholinguistic development (expressive and receptive), performance IQ, and the Basic Number Skills subtest of the British Ability Scales. Number skills data for this sample were compared with normative population data. Consistent with predictions that language impairment would impact on numerical development, average standard scores were more than 1 SD below the population mean at both ages. Although the children showed improvements in raw scores at the second wave of the study, the discrepancy between their scores and the population data nonetheless increased over time. Regression analyses showed that, after controlling for the effect of PIQ, language skills explained an additional 19 and 17% of the variance in number skills for ages 7 and 8, respectively. Furthermore, logistic regression analyses revealed that less improvement in the child's language ability over the course of the year was associated with a greater odds of a drop in performance in basic number skills from 7 to 8 years. The results are discussed in relation to the interaction of linguistic and cognitive factors in numerical development and the implications for mathematical education
Memory and Language in Middle Childhood in Individuals with a History of Specific Language Impairment
No full textThis 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) peers were administered sentence repetition, phonological short term memory (PSTM) and grammatical morphology tasks. Children with a history of SLI were divided into four subgroups: specific language impairment, non-specific language impairment, low cognition with resolved language and resolved. Performance on the sentence repetition task was significantly impaired in all four subgroups of children with a history of SLI when compared to their age peers. Regression analyses revealed grammatical knowledge was predictive of performance for TD children and children with a history of SLI. However, memory abilities were significantly predictive of sentence repetition task performance for children with a history of SLI only. Processes involved in sentence repetition are more taxing of PSTM for individuals with a history of SLI in middle childhood in a way that does not appear to be the case for TD children. © 2013 Hesketh, Conti-Ramsden
Social Difficulties and Victimization in Children with SLI at 11 Years of Age
No full textSpecific language impairment is sometimes thought to be associated with concurrent difficulties in the area of social and behavioral development (N. Botting & G. Conti-Ramsden, 2000; D. P. Cantwell & L. Baker, 1987; M. Fujiki, B. Brinton, & C. Todd, 1996; S. Redmond & M. Rice, 1998). The present study follows a group of 242 children, initially studied at age 7 years when they attended language units in England, and assesses their social and behavioral status at age 11 years. In total, 64% of the children were found to have scores on the Rutter behavioral questionnaire (M. Rutter, 1967) of 9 or above (clinical threshold); 34% scored over the threshold for the Strengths and Difficulties questionnaire (R. Goodman, 1997); and 39% scored below average on the Peer Competence subscale of the Harter Perceived Competence Scale (S. Harter & R. Pike, 1984). On further analysis, these generalized difficulties were characterized mainly by poor social competence. In addition, 36% of the cohort were at risk of being regular targets for victimization compared to 12% of a comparison sample of typically developing peers. Few associations were found between social outcome and other measures, including nonverbal intelligence, overall linguistic skill, gender, and longitudinal measures taken previously. Importantly, however, pragmatic language difficulties measured on the Children's Communication Checklist (D. V. M. Bishop, 1998) were most strongly related to poor social outcome and to expressive language related to victimization
Achieving international consensus for the prevention of orthopaedic wound blistering: results of a Delphi survey
No full textThis article presents the results of an international 2 stage Delphi survey carried out via e-mail to achieve consensus as to the most effective postoperative wound management to prevent blistering and other complications. Seventeen prospective participants were invited to be members of the Delphi Panel of which 13 agreed to be involved. The panel suggested that an ideal wound dressing would conform easily to the wound, be easy to apply and remove, allow for swelling and minimise pain on removal. Participants were in agreement that the primary wound dressing should be left in situ for as long as possible, providing there was no excessive oozing or signs of infection. The authors recognise that the Delphi Panel was relatively compact; however, the study arguably provides some useful data that can be used to identify the consequences of wound blistering and important factors that need to be considered when choosing a wound dressing to prevent blistering
The relation between receptive grammar and procedural, declarative, and working memory in specific language impairment
No full textWhat memory systems underlie grammar in children, and do these differ between typically developing children and children with specific language impairment (SLI)? Whilst there is substantial evidence linking certain memory deficits to the language problems in children with SLI, few studies have investigated multiple memory systems simultaneously, examining not only possible memory deficits but also memory abilities that may play a compensatory role. This study examined the extent to which procedural, declarative, and working memory abilities predict receptive grammar in 45 primary school aged children with SLI (30 males, 15 females) and 46 typically developing (TD) children (30 males, 16 females), both on average 9;10 years of age. Regression analyses probed measures of all three memory systems simultaneously as potential predictors of receptive grammar. The model was significant, explaining 51.6% of the variance. There was a significant main effect of learning in procedural memory and a significant group x procedural learning interaction. Further investigation of the interaction revealed that procedural learning predicted grammar in TD but not in children with SLI. Indeed, procedural learning was the only predictor of grammar in TD. In contrast, only learning in declarative memory significantly predicted grammar in SLI. Thus, different memory systems are associated with receptive grammar abilities in children with SLI and their TD peers. This study is, to our knowledge, the first to demonstrate a significant group by memory system interaction in predicting grammar in children with SLI and their TD peers. In line with Ullman’s Declarative/Procedural model of language and Procedural Deficit Hypothesis of SLI, variability in understanding sentences of varying grammatical complexity appears to be associated with variability in procedural memory abilities in TD children, but with declarative memory, as an apparent compensatory mechanism, in children with SLI
Frequency of educational computer use as a longitudinal predictor of educational outcomes in young people with specific language impairment
No full textComputer use draws on linguistic abilities. Using this medium thus presents challenges for young people with Specific Language Impairment (SLI) and raises questions of whether computer-based tasks are appropriate for them. We consider theoretical arguments predicting impaired performance and negative outcomes relative to peers without SLI versus the possibility of positive gains. We examine the relationship between frequency of computer use (for leisure and educational purposes) and educational achievement; in particular examination performance at the end of compulsory education and level of educational progress two years later. Participants were 49 young people with SLI and 56 typically developing (TD) young people. At around age 17, the two groups did not differ in frequency of educational computer use or leisure computer use. There were no associations between computer use and educational outcomes in the TD group. In the SLI group, after PIQ was controlled for, educational computer use at around 17 years of age contributed substantially to the prediction of educational progress at 19 years. The findings suggest that educational uses of computers are conducive to educational progress in young people with SLI
Bullying risks of 11-year-old children with specific language impairment (SLI): Does school placement matter?
No full textIn addressing an issue rarely explored in research literature, the prevalence and severity of the risk of being bullied at school was measured in 100 children with specific language impairment (SLI). Participants attended a range of different educational placement types and these were compared for bullying risk. Furthermore, the risk encountered by children with SLI was compared with that of normally developing age-matched peers. Each participant completed a questionnaire and it was found that 36% of participants with SLI considered themselves at risk of being bullied in school compared with only 12% of the normally developing cohort. No statistically significant difference was found between the risk experienced by participants with SLI attending mainstream education and that by participants attending special education placements. Possible explanations for the results are offered and the relevance of the findings in the context of optimizing the educational experience of children with SLI is highlighted
