In this study, we performed a fine grained analysis of writing by children with a specific language impairment (SLI) and examined the contribution of oral language, phonological short-term memory (STM), nonverbal ability, and word reading to three writing constructs (productivity, complexity and accuracy). Forty-six children with SLI were compared with 42 children matched for chronological age, receptive vocabulary (N = 46) and reading decoding (N = 46) on a measure of narrative writing. The SLI group performed worse on all measures compared to children of a similar chronological age. The SLI group produced a greater proportion of orthographic spelling errors than children with similar receptive vocabularies, but were comparable to children matched for reading decoding. The children with SLI showed specific difficulties in the omission of whole words (e.g. auxiliary verbs and subject nouns) and omissions of grammatical morphology (e.g. past tense—ed) reflecting the difficulties shown in their oral language. Receptive grammar made a significant contribution to writing complexity and accuracy. Phonological fluency contributed to writing productivity, such as the production of diverse vocabulary, ideas and content and writing fluency. Phonological STM and word reading explained additional variance in writing accuracy over and above the SLI group’s oral language skills.  相似文献

This study investigated kindergarten, preschool, and first‐grade children who were typical or specific language impaired (SLI) to determine whether there were developmental differences in their phonological awareness abilities (i.e., syllable, onset/rime, phonemes). Results revealed a significant difference between children who were typical and children who were SLI on the sound‐segmentation tasks. The children who were typical were more effective at segmenting than were children who were SLI. Significant differences were also noted between the types of phonological task completed among participants. The combined data from this study revealed developmental trends in phonological awareness for the typical population. The developmental trend was not observed in the SLI population, however. Clinical implications are suggested. © 2010 Wiley Periodicals, Inc.  相似文献

Children with specific language impairments (SLI) have difficulties in producing written text. It was hypothesised that the constraints on writing in children with SLI were similar to typically developing younger children with the same level of vocabulary knowledge. Twenty‐three children with SLI (aged 10:5) were matched with 23 children for chronological age (CA) and 23 children for vocabulary levels (VC). Children with SLI performed significantly below their CA peers but not their VC peers on all aspects of writing including spelling. Regression analyses indicated that written text measures of spelling errors and oral language measures of vocabulary were significant predictors of writing products for both the children with SLI and their VC peers. This highlights the importance of oral and written language for the quality of children's written text and indicates that the writing of children with SLI was commensurate with their vocabulary and spelling levels. The results point to the role of both phonological and non‐phonological processes in written text production in struggling writers.  相似文献

The aim of this study was to determine if phonological processing deficits in specific reading disability (SRD) and specific language impairment (SLI) are the same or different. In four separate analyses, a different combination of reading and spoken language measures was used to divide 73 children into three subgroups: poor readers with average spoken language (SRD), poor readers with poor spoken language (SRD + SLI) and average readers with poor spoken language (SLI). These groups were compared on five phonological processing measures. The SRD group had deficits in neural representations of phonemes, phoneme discrimination, phoneme awareness and rapid naming. The SRD + SLI group had more severe deficits than the SRD group on half of these measures, as well as phonological short‐term memory. Children with SLI were free from phonological processing deficits. Thus, phonological processing deficits were the same or different in SRD and SLI, depending on how SRD and SLI were defined, and how phonological processing was measured.  相似文献

The purpose of this study was to examine the utility of the Spelling Sensitivity Score (SSS) beyond percentage correct scoring in analyzing the spellings of children with specific language impairment (SLI). Participants were 31 children with SLI and 28 children with typical language in grades 2–4. Spellings of individual words were scored using two methods: (1) percentage correct and (2) SSS. Children with SLI scored lower than children with typical language when spelling was analyzed with percentage correct scoring and with SSS scoring. In addition, SSS scoring highlighted group differences in the nature of spelling errors. Children with SLI were more likely than children with typical language to omit elements and to represent elements with an illegal grapheme in words, whereas children with typical language were more likely than children with SLI to represent all elements with correct letters.  相似文献

This longitudinal study investigated growth in reading-related skills between Grade 1 and 4 for language minority (LM) learners and their native English-speaking classmates from similarly low socioeconomic backgrounds (N = 166). Growth trajectories were compared by language background and by Grade 4 reading difficulties, with the goal of informing decisions about how early LM learners can undergo screening for risk of reading difficulties. As a group, LM learners demonstrated weaknesses in vocabulary and oral comprehension and strengths in phonological awareness that were apparent in Grade 1 and consistent through Grade 4. LM learners also demonstrated early strengths in letter-word identification but fell far below national norms by Grade 4. The subset of LM learners with word reading difficulties demonstrated major weaknesses in vocabulary, oral comprehension, phonological awareness, and working memory, whereas LM learners with specific reading comprehension difficulties demonstrated major weaknesses in vocabulary and oral comprehension; these weaknesses were apparent in Grade 1 and consistent through Grade 4, suggesting the importance of early assessment and intervention.  相似文献

The present study addresses the distinction between specific (SLI) and nonspecific (NLI) language impairment at an etiological level by estimating the relative genetic and environmental contributions to language impairment in children with SLI and NLI. Drawing on a large longitudinal twin study, we tested a sample of 356 four-and-a-half-year-old children with low language ability and their twin partners at home on a range of language and nonverbal measures. For children whose language and nonverbal abilities were both low (NLI), genetic influence on language impairment was moderate and shared environmental influence was substantial. A similar pattern emerged for children whose language difficulties occurred in apparent isolation (SLI), although there was a trend for the genetic effects to be smaller for SLI than for NLI: Group heritability was .18 for SLI and .52 for NLI. Probandwise cross-concordances were suggestive of some genetic overlap between these two groups, but not with a subgroup of children with more severe cognitive delay.  相似文献

The relationship between specific subtypes of speech language impairment (SLI) and concomitant social competence and behavioral adjustment was investigated. Teachers and parents completed behavior ratings of SLI preschoolers enrolled in a language‐based intervention program and preschoolers without language impairment, including the Parent‐Child Rating Scale (P‐CRS), Teacher‐Child Rating Scale (T‐CRS), and Social Competence and Behavior Evaluation Scale (SCBE). Teacher and parent ratings were analyzed across four SLI subtypes: expressive, receptive, pragmatic, and articulation. Results confirmed that children with greater language impairments had significantly more behavioral problems and poorer social competence than those children with articulation‐only disorders and children without any impairments, and these results were observed in both home and school environments. SLI children had particular difficulty with task orientation, assertiveness, peer social skills, and frustration tolerance, and were more likely to be dependent and isolated in the classroom. Implications for assessment and intervention of SLI children were discussed. © 2005 Wiley Periodicals, Inc. Psychol Schs 42: 373–387, 2005.  相似文献

Children identified as normal or as specifically language impaired (SLI) were given speech, language, and intelligence testing on a longitudinal basis. Fourteen normal and 29 SLI children between the ages of 4 1/2 and 8 years were tested at Time 1. They were retested three to four years later when they were 8 to 12 years old. The results indicated that both the normal and the SLI children continued to develop skills in receptive and expressive language and speech articulation across the 3- to 4-year period intervening between evaluations. Overall, however, the SLI children appeared to develop language skills at a slower than normal rate and 80% of them remained language impaired at Time 2. In addition, the majority of the SLI children manifested reading impairment at Time 2, while none of the normal children did so. The implications for the educational management of SLI children are discussed. Research supported by the March of Dimes, Grant #12-84.

This study investigated the role of cognitive and language skills as predictors of early literacy skills in children with Specific Language Impairment. A range of cognitive and linguistic skills were assessed in a sample of 137 eight-year-old children with SLI at the beginning of the school year, and 6 months later on word decoding and reading comprehension. The cognitive and linguistic measures revealed four factors that were called language, speech, short-term memory, and phonological awareness. Structural equation modeling showed word decoding to be predicted by speech, short-term memory, and phonological awareness, whereas reading comprehension was predicted by word decoding skills and short-term memory. It can be concluded that in children with SLI variations in early word decoding are mostly determined by speech abilities and short-term memory, and to a lesser extent by phonological awareness. Moreover, reading comprehension turns out to be highly dependent on word decoding and short-term memory.  相似文献

Many UK children with severe and persistent language impairment (SLI) attend local mainstream schools. Although this should provide an excellent language-learning environment, opportunities may be limited by difficulties in sustaining time-consuming, child-specific learning activities; restricted co-professional working, and the complex classroom environment.
Two language intervention studies in mainstream Scottish primary schools showed children with SLI receiving intervention from speech and language therapists (SLTs) or their assistants made more progress in expressive language than similar children receiving intervention from education staff. Potential reasons for this difference are sought in the amount of tailored language-learning activity undertaken; how actively school staff initiated contact with SLTs; and the language demands of the classroom. Tailored language learning appears to be a differentiating factor.
A language support model, reflecting views of teachers and SLTs about encouraging language development for children with SLI within the ecology of the mainstream primary classroom, is also outlined.  相似文献

We examined the efficacy of 20 weeks of individual supplemental phonics-based instruction for language minority (LM) and non-LM first graders. Students were designated LM if the primary home language was not English (otherwise non-LM). Those performing in the bottom half of their classroom LM/non-LM group in letter knowledge and phonological awareness were randomly assigned to treatment and control conditions. Treatment included alphabetics, decoding, and oral reading practice. Results showed that treatment students (n?=?93) outperformed controls (n?=?94) on 5 of the 6 posttests; however, LM students exhibited lower treatment response on passage reading fluency. Pretest word reading did not moderate treatment response, and LM students with greater baseline vocabulary showed greater treatment response on posttest word reading and spelling.  相似文献

This study examined (1) whether working memory and higher-level languages skills—inferencing and comprehension monitoring—accounted for individual differences among Chinese children in Chinese reading comprehension, after controlling for age, Chinese word reading and oral language skills, and (2) whether children with specific language impairment (SLI) or dyslexia showed deficits in these skills. Eighty-two Cantonese Chinese-speaking children between the age of 7; 8–9; 5 were assessed. Regression analyses on the full sample offered support for the first question. The children were also classified into four groups: Typically-developing (TD; N = 34), specific language impairment-only (SLI-only; N = 18), SLI-dyslexia comorbid (SLI-D; N = 22) and dyslexia-only (D-only; N = 8). Pair-wise comparisons focusing on the second question revealed that both the SLI-only and the D-only group performed worse than the TD group in reading comprehension after controlling for age and nonverbal intelligence. The SLI-only and the D-only group showed a different profile of deficits: only the SLI-only group performed worse than the TD group in working memory, comprehension monitoring, and inferencing. The SLI-D comorbid group did worse than the SLI-only, but not the D-only group, in reading comprehension. The SLI-D comorbid group did not do worse than either single diagnosis group in the higher-level language skills associated with reading comprehension. These findings suggested adopting different intervention approaches for reading comprehension difficulties in children with SLI versus children with dyslexia.  相似文献

Given the research that suggests the social use of language is the latest developing aspect of language, it was hypothesized that children with speech/language impairment (SLI) are particularly susceptible to social interaction difficulties, resulting in diminished social competence. This hypothesis was explored with SLI and non‐language‐impaired (NLI) 4‐ and 5‐year‐old children by gathering measures of social problem solving ability (as rated by teachers, parents, and peers), emotion knowledge, and language development. Results provided partial support for the hypothesis above. Speech/language‐impaired children were rated significantly lower on parent ratings of self‐control and higher in internalizing behaviors, and lower on teacher ratings of assertiveness, than the NLI controls. There were no differences noted on peer sociometric ratings or mutual friendships. However, SLI children scored lower on a stereotypical test of emotional knowledge, while scoring similarly to NLI controls on a nonstereotypical test. A test of language development (TELD‐2) differentiated the SLI and NLI groups, both expressively and receptively. In addition, the TELD‐2 indicated a significant difference in semantic processing errors, but not syntax errors, between the two groups. The differential effects of speech/language impairment on the development of social competence were explored. © 2004 Wiley Periodicals, Inc. Psychol Schs 41: 313–321, 2004.  相似文献

Recent research has found that the acquisition of theory of mind (ToM) is delayed in children with specific language impairment (SLI). The present study used a battery of ToM and visual perspective taking (VPT) tasks to investigate whether the delayed acquisition of ToM in children with SLI is associated with delayed VPT development. Harris' (1992, 1996) simulation theory predicts that the development of VPT will be delayed. Participants were 20 children with SLI (M=62.9 months) and 20 typically developing children (M=61.2 months) who were matched for nonverbal ability, gender, and age. The results supported Harris' theory and a role for language in ToM and VPT development.  相似文献

Children's early spelling attempts (invented spellings) and underlying component skills were evaluated in a sample (N = 115) of 5-year-old children. Letter-sound knowledge and phoneme awareness were shown to be important predictors of invented spelling performance in this age group. The results also showed associations between invented spelling and measures of orthographic awareness and morphological processing. The findings support the view that invented spelling is a developmentally complex and important early literacy skill that involves phonemic awareness, letter sound knowledge, and other oral language skills and orthographic knowledge.  相似文献

The present 4-year longitudinal study examined preschool predictors of Grade 1 dyslexia status in a Chinese population in Hong Kong where children started learning to read at the age of three. Seventy-five and 39 Chinese children with high and low familial risk respectively were tested on Chinese word reading, oral language skills, morphological awareness, phonological skills, rapid naming, and print-related skills from age 4 to 6 and a standardized dyslexia test at age 7. Results showed that children of the high risk group performed significantly worse than the low risk group in Chinese literacy, phonological awareness, and orthographic skills at age 7. All the children with dyslexia had word reading difficulties in at least one preschool year. Results of the logistic regression showed that preschool verbal production, syllable deletion, and letter naming were the best predictors of dyslexia outcome at age 7. As in alphabetic languages, preschool oral language skills like verbal production, phonological skills, and print-related skills are the most significant predictors of children’s later reading difficulties.  相似文献

This study examined the importance of morphological awareness in Korean–English biliteracy acquisition. English is an opaque orthographic system, in which letters and sounds have indirect correspondences. Korean Hangul, on the other hand, is a transparent orthographic system where there are direct letter-sound correspondences. Sixty-five children from Grades 2 to 4 were tested on a set of comparable Korean and English tasks tapping into oral vocabulary, phonemic awareness, morphological awareness, real word reading, and passage reading comprehension. Results showed that morphological awareness explained a significant amount of variance in word reading and reading comprehension within both Korean Hangul and English, suggesting that morphological awareness is important not only in an opaque orthography but also in a transparent orthography. Furthermore, morphological awareness in one language uniquely predicted a significant amount of variance in reading real words in the other language, suggesting that morphological awareness facilitates word reading across different orthographies.  相似文献

Research suggests that children with specific language impairment (SLI) have processing limitations; however, the mechanisms involved have not been well defined or investigated in a theory-guided manner. The theory of constructive operators was used as a framework to explore processes underlying limited processing capacity in children with SLI. Mental attentional capacity, mental attentional interruption, and 2 specific executive functions (shifting and updating) were examined in 45 children with SLI and 45 children with normally developing language, aged 7 to 12 years. The results revealed overall group differences in performance on measures of mental attention, interruption, and updating, but not shifting. The findings supported the premise that mental attention predicted language competence, but that this relationship was mediated partially by updating.  相似文献

The authors used a large sample of children (N ≈ 7,400) participating in the Early Childhood Longitudinal Study--Kindergarten Cohort (ECLS-K) to estimate kindergarten children's academic achievement growth trajectories in reading and mathematics. The authors were particularly interested in whether the growth trajectories of children with learning disabilities (LD) or speech language impairments (SLI)--as well as those of other groups of children--were consistent with a cumulative or compensatory developmental cycle. Both LD and SLI children displayed significantly lower levels of kindergarten reading achievement than nondisabled children. However, and over the subsequent 5 years of elementary school, only children with SLI lagged increasingly behind nondisabled peers in their reading skills growth. The authors observed a different pattern for mathematics achievement. Children with LD, but not SLI, lagged increasingly behind nondisabled children in their mathematics skills growth. The authors also observed some consistency in "poor-get-poorer" effects across reading and mathematic achievement for additional population subgroups. Those kindergarten children who were from lower socioeconomic status families, who were African American, and who more frequently displayed learning-related behavior problems initially had lower levels of reading and mathematics achievement and also lagged increasingly behind in their acquisition of these skills over time. Some groups of children, including those with SLI, experience a cumulative rather than a compensatory cycle of achievement growth.  相似文献
