The alphasyllabary of Kannada comprises more than 400 symbols called akshara; each symbol is visuo-spatially complex with a consistent representation at the dual levels of the syllable and the phoneme.
We investigated reading difficulties in Kannada among 8–12 year old children by conducting a between-groups followed by a
case series analysis. We compared the children with reading difficulties with same age competent readers and younger readers
who were similar in language level, matched on measures of vocabulary, syntactic processing, and morphological processing.
Reading difficulties were characterized by poor akshara knowledge. Concomitant impairments were in syllable and phoneme level
phonological skills, in rapid naming and in oral language skills. The case series analysis highlighted the variability of
profiles among poor readers with the most common impairments being in akshara knowledge and phonological processing. Sub-groups
of poor readers showed additional deficits in oral language, rapid naming, and visual processing skills. Together our findings
indicate that the core deficit associated with reading difficulty in the alphasyllabary of Kannada is in the phonological
domain. However, accompanying deficits in related skills, including visual processing, can further inhibit reading attainment.
The findings from this study support a multifactorial model of reading development. 相似文献

The present study examined factors that influence the process of learning to read in a second language. The Hebrew reading
comprehension skills of 68 Russian-speaking children (mean age 7 years 6 months) were screened at the start of Grade 2. From
this sample, 40 participants were selected: 20 successful learners and 20 unsuccessful learners. These two groups were then
tested on a wide range of language skills (e.g., phonological processing, vocabulary, syntactic and morphological awareness)
in both languages (Hebrew and Russian) and reading skills in Hebrew (e.g., reading speed and accuracy).
Two factors, level of spoken Hebrew and phonological awareness deficits in both languages, were significant. Phonological
awareness difficulties constituted the key factor associated with poor decoding whereas insufficient mastery of spoken Hebrew
was important in the case of reading comprehension. An interesting dissociation was also found in our poor readers between
impaired phonological awareness and other unimpaired phonological processing abilities such as oral pseudoword repetition
and working memory. These findings suggest that, in addition to poor spoken L2 proficiency, poor readers are characterized
more by a metalinguistic rather than a linguistic deficit in their native tongue. 相似文献

Whereas many studies point to a positive relationship between phonological skills and reading in English, little is known about these relationships for children learning to read in a morphemic orthography such as Chinese. The aim of this study was to examine the relationships among reading ability, phonological, semantic and syntactic skills in Chinese. The participants were 196 grade 1 to grade 4 Chinese children in Hong Kong. A word recognition task in Chinese was developed and children who scored in the lowest quartile were classified as poor readers. The children were administered phonological tasks (tone and rhyming discrimination), semantic tasks (choosing similar words and sentences meanings), a syntactic task (oral cloze), and a working memory task. The results showed that word recognition was highly correlated with phonological skills and semantic processing, and was only moderately related to syntactic knowledge and working memory. Poor readers showed a significant lag in the development of these skills with the most significant problems at the phonological and semantic levels. Phonological skills are important to the acquisition of reading skills in both Chinese and English. 相似文献

The purpose of this study was to determine whether children with dyslexia, that is, children whose reading levels were significantly lower than would be predicted by their IQ scores, constituted a distinctive group when compared with poor readers, that is, children whose reading scores were consistent with their IQ scores. The performance of children with dyslexia, poor readers, and normally achieving readers was compared on a variety of reading, spelling, phonological processing, language, and memory tasks. Although the children with dyslexia had significantly higher IQ scores than the poor readers, these two groups did not differ in their performance on reading, spelling, phonological processing, or most of the language and memory tasks. In all cases, the performance of both reading disabled groups was significantly below that of nondisabled readers. The findings were similar whether absolute difference or regression scores were used. Reading disabled children, whether or not their reading is significantly below the level predicted by their IQ scores, experience significant problems in phonological processing, short-term and working memory, and syntactic awareness. On the basis of these data, there does not seem to be a need to differentiate between individuals with dyslexia and poor readers. Both of these groups are reading disabled and have deficits in phonological processing, verbal memory, and syntactic awareness. 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 determine the components of working memory (WM) that underlie less skilled readers' comprehension and word recognition difficulties. Performance of 3 less skilled reading subgroups---children with reading disabilities (RD) in both word recognition and comprehension; children with comprehension deficits only; and children with low verbal IQ, word recognition, and comprehension (poor readers)--was compared to that of skilled readers on WM, short-term memory (STM), processing speed, executive, and phonological processing measures. Ability group comparisons showed that (a) skilled readers outperformed all less skilled readers on measures of WM, updating, and processing speed; (b) children with comprehension deficits only outperformed children with RD on measures of WM, STM, phonological processing, and processing speed; and (c) children with RD outperformed poor readers on WM and phonological processing measures. A hierarchical regression analysis showed that (a) subgroup differences on WM tasks among less skilled readers were moderated by a storage system not specific to phonological skills, and (b) STM and updating contributed significant variance to WM beyond what was contributed by reading group classification. The latter finding suggested that some differences in storage and executive processing emerged between skilled and less skilled readers that were not specific to reading. 相似文献

Difficulties in reading and language skills which persist from childhood into adult life are the concerns of this article.
The aims were twofold: (1) to find measures of adult reading processes that validate adults’ retrospective reports of difficulties
in learning to read during the school years, and (2) to search for indications of basic deficits in phonological processing
that may point toward underlying causes of reading difficulties. Adults who reported a history of difficulties in learning
to read (n=102) were distinctly disabled in phonological coding in reading, compared to adults without similar histories (n=56). They were less disabled in the comprehension of written passages, and the comprehension disability was explained by
the phonological difficulties. A number of indications were found that adults with poor phonological coding skills in reading
(i.e., dyslexia) have basic deficits in phonological representations of spoken words, even when semantic word knowledge, phonemic
awareness, educational level, and daily reading habits are taken into account. It is suggested that dyslexics possess less
distinct phonological representations of spoken words.

Reading,syntactic, and working memory skills of bilingual Portuguese-English Canadian children 总被引：1，自引：0，他引：1
The purpose of the study was to examine the nature of language, memory, and reading skills of bilingual students and to determine the relationship between reading problems in English and reading problems in Portuguese. The study assessed the reading, language, and memory skills of 37 bilingual Portuguese-Canadian children, aged 9–12 years. English was their main instructional language and Portuguese was the language spoken at home. All children attended a Heritage Language Program at school where they were taught to read and write Portuguese. The children were administered word and pseudoword reading, language, and working memory tasks in English and Portuguese. The majority of the children (67%) showed at least average proficiency in both languages. The children who had low reading scores in English also had significantly lower scores on the Portuguese tasks. There was a significant relationship between the acquisition of word and pseudoword reading, working memory, and syntactic awareness skills in the two languages. The Portuguese-Canadian children who were normally achieving readers did not differ from a comparison group of monolingual English speaking normally achieving readers except that the bilingual children had significantly lower scores on the English syntactic awareness task. The bilingual reading disabled children had similar scores to the monolingual reading disabled children on word reading and working memory but lower scores on the syntactic awareness task. However, the bilingual reading disabled children had significantlyhigher scores than the monolingual English speaking reading disabled children on the English pseudoword reading test and the English spelling task, perhaps reflecting a positive transfer from the more regular grapheme phoneme conversion rules of Portuguese. In this case, bilingualism does not appear to have negative consequences for the development of reading skills. In both English and Portuguese, reading difficulties appear to be strongly related to deficits in phonological processing. 相似文献

Ameliorating Early Reading Failure by Integrating the Teaching of Reading and Phonological Skills: The Phonological Linkage Hypothesis 总被引：15，自引：0，他引：15
We present a longitudinal intervention study of children experiencing difficulties in the early stages of learning to read. Our subjects, 7-year-old poor readers, were divided into 4 matched groups and assigned to 1 of 3 experimental teaching conditions: Reading with Phonology, Reading Alone, Phonology Alone, and a Control. Although the Phonology Alone group showed most improvement on phonological tasks, the Reading with Phonology group made most progress in reading. These results show that interventions to boost phonological skills need to be integrated with the teaching of reading if they are to be maximally effective in improving literacy skills. 相似文献

The purpose of this study was to investigate the hypothesis that the manner in which a reading disability is defined will influence the conclusions that are made about the characteristics of the disability. To test this hypothesis, learning disabled and normally achieving children, aged 6 to 14, were administered tasks measuring grammatical, shortterm memory, phonological, reading, and visual-spatial skills. The poor readers were divided into groups of poor readers with
These children were compared with children who had normal reading scores. Children with deficits in phonics and/or word recognition scored significantly below normal on all the cognitive tests, except some of the visual-spatial tasks. Reading comprehension difficulties were characterized by average phonics, word recognition, and language skills but below average scores on some memory tasks. Slow readers had cognitive profiles similar to the normal children. The presence of a deficit in phonics and/or word recognition constituted the basis of the most serious impairment of language and memory functioning. Reading disabled children, defined in this manner, appear to be reasonably homogeneous in regard to the presence of language and memory problem. There does not appear to be evidence for a distinctive non-language impaired subtype within this type of reading disability. Children with low comprehension scores and/or slow readers did not have language problems. The definition of a reading disability appears to determine the subtypes and characteristics of reading disability that will emerge. 相似文献

Reading is not merely "language by eye." Rather, it builds fundamentally on primary language processes. For hearing readers, this means that spoken language processes, including phonological processes, are critical to high achievement in reading. We examine the implications of this fact for deaf readers by considering the relationship between language and reading and by reviewing the research on the use of phonology by deaf readers. The research, although mixed in its results, suggests that the use of phonology is associated with higher levels of reading skill among deaf readers. We examine related questions, including the additional semantic and visual strategies available to deaf readers, how some deaf readers gain access to the spoken structure of language, and implications for how to improve reading achievement. 相似文献

Previous research has indicated a relationship between reading ability and the integrity of certain phonological processing skills--skills that operate on the sound structure of language. This study shows how the deficient phonological processing skills of poor beginning readers can impair their comprehension of spoken phrases and sentences that are disambiguated by prosodic cues (i.e., pitch, stress, and pause). Following a brief summary of the available research literature, two new experiments are reported to illustrate that poor readers do not interpret certain sentences as accurately as good readers do, because they are less able to hold phonological material temporarily in working memory. Further insight into the basis of these differences between good and poor readers is provided by two additional pieces of evidence: The differences between good and poor readers are analogous to those between older and younger children readers, and the performance of poor readers tends to resemble that of younger children reading at their same level (i.e., reading-ability-matched controls). Apparently, good and poor readers tend to differ in the rate at which they develop phonological processing skills. 相似文献

This study aimed to determine whether the reading skills of third‐grade schoolchildren are associated with their preferences for semantic, phonological, and shape competitors (images or printed words) after being exposed to a spoken critical word. Two groups of children participated: skilled readers and less‐skilled readers. Through a language‐mediated visual search, children's fixations on the three competitors and a distractor were measured. When looking at images, both groups of readers preferred to look at the semantic competitor. When reading words, both groups showed a preference for the phonological competitor, but only skilled readers were sensitive to semantic information. These results suggest that early reading skills influence access to different types of representations in response to hearing a word, and they confirm the existence of a cascaded activation of information retrieval in childhood. 相似文献

One goal of this longitudinal study was to examine whether the predictors of reading skills in Grade 3 would differ between English as a second language (ESL) students and native English-speaking (L1) students. Phonological processing, syntactic awareness, memory, spelling, word reading, and lexical access skills were assessed in kindergarten and in Grade 3. The results indicated that in kindergarten, the ESL group had significantly lower scores on phonological processing, syntactic awareness, spelling, and memory for sentences tasks. However, in Grade 3, the ESL group performed in a similar way to the L1 group except on the syntactic awareness task. The combination of the two kindergarten measures, memory for sentences and Oral Cloze, and the combination of phonological processing and letter identification all contributed equally to predicting the L1 students' word-reading skills. However, for ESL students, letter identification and phonological processing made much larger contributions to predicting Grade 3 reading ability. Another goal of this study was to assess the procedures used to identify reading disability in the ESL and L1 student sample. Performance on two measures—letter identification and phonological awareness in kindergarten—predicted whether students would be classified in Grade 3 as at risk or having typical reading development for the ESL and L1 groups. The ESL children developed strong reading skills, and their status as ESL speakers did not put them at risk for reading difficulties in Grade 3. ESL students were not at any particular risk for reading difficulties after 4 years in Canadian schooling with an adequate balanced literacy program. 相似文献

This study examined phonological awareness at the level of phonemes and rhyme and related this to nonword naming ability. Poor readers were compared with 11 year old chronological-age controls and 8 year old reading-age controls. The poor reader group was impaired for chronological age in all tasks, and impaired for reading age at nonword naming and phoneme deletion. The poor readers' rhyming skills, however, were commensurate with reading age. Individual variation was observed together with exceptions to the group findings; most poor readers performed within the range of the reading-age controls on the phonological tasks and in nonword naming. Dissociations in phonological skills were evident, including indications that intact awareness of rhyme may not be a prerequisite for the development of phoneme awareness. Furthermore, phoneme awareness correlated significantly with poor readers' word and nonword reading ability, whereas rhyming skill did not. Therefore, phoneme awareness may be more important than rhyming skill in understanding reading disorders. 相似文献

One of the most usual flaws that lead to literacy disability regards cognitive difficulties and alterations some children
present in the literacy process. Many studies have found alterations in phonological processing, more specifically in phonological
working memory (PWM) and phonological awareness (PA). Therefore, our aim was to identify alterations in skills of phonological
working memory, phonological awareness and language (semantic, syntactic and phonological aspects) of Brazilian children with
literacy disabilities (age 7–8). They were divided into two groups: (1) Group of Normal Literacy (NL); and (2) Group With
Literacy Disabilities (LD). The evaluation comprised tests that assessed general cognitive functions and the skills at stake.
The LD presented a poorer performance than the NL in the skills of PWM, PA and language aspects. The factor analysis showed
that these skills prevailed in differentiating the groups. Thus, children with literacy disabilities presented deficits in
phonological processing and language. These deficits seem to be a result of alterations of the phonological representations
and poor language skills that are prior to the literacy period. Consequently, we believe that the early identification of
these alterations can be very useful for the prevention of future literacy problems. 相似文献

To examine phonological core deficits and variable orthographic competence, Dutch poor readers were investigated as they began instruction in reading in English (at about 14 years of age). A subgroup of poor readers with good orthographic competence in English (Poor/Good) and a subgroup with poor orthographic competence in English (Poor/Poor) were identified. Verbal and reading tasks in Dutch and English were assessed twice within a 10-month interval, and the scores of the two measurements were combined to gain stability. For both subgroups, we found indications that phonological core deficits and variable differences in orthographic competence transferred across the two languages. However, the Poor/Good subgroup did not show the weaknesses in serial rapid naming and semantic fluency of the Poor/Poor subgroup in both languages. Moreover, the Poor/Good readers were relatively good in reading skills and verbal learning in English. They had a specific reading disability at the phonemic level but also had compensatory skills at the level of syllables and words that help them to acquire English as second language. In contrast, the Poor/Poor subgroup had a more general reading disability, most prominently present in L2. The results are discussed in terms of orthographic differences between Dutch and English, the phonological-core variable-differences model, and "subtypes" of dyslexia. 相似文献

The role of speed of processing, rapid naming, and phonological awareness in reading achievement 总被引：5，自引：0，他引：5

This study investigated the role of speed of processing, rapid naming, and phonological awareness in reading achievement. Measures of response time in motor, visual, lexical, grammatical, and phonological tasks were administered to 279 children in third grade. Measures of rapid object naming, phonological awareness, and reading achievement were given in second and fourth grades. Reading group comparisons indicated that poor readers were proportionally slower than good readers across response time measures and on the rapid object naming task. These results suggest that some poor readers have a general deficit in speed of processing and that their problems in rapid object naming are in part a reflection of this deficit. Hierarchical regression analyses further showed that when considered along with IQ and phonological awareness, speed of processing explained unique variance in reading achievement. This finding suggests that a speed of processing deficit may be an "extraphonological" factor in some reading disabilities. 相似文献

This study examined the contributions of phonological processing and oral language abilities to reading and reading disabilities in young children. Two approaches were taken. First, 604 participants were divided into good and poor readers on the basis of reading performance in second grade. Reading groups were then compared in terms of kindergarten phonological processing and other language abilities. In a second approach, multiple regression was employed to investigate the relative contributions of phonological processing and oral language abilities in predicting second-grade reading achievement across reading groups. Results indicated that over 70% of poor readers had a history of language deficits in kindergarten. Most of these children had problems in both phonological processing and oral language. Regression analyses further indicated that oral language and phonological processing abilities each accounted for unique variance in reading achievement. These results suggest that language-based theories of reading and reading disabilities must include both phonological processing and oral language abilities. 相似文献

The aim of the current study was to further explore the connection between verbal short-term recall and phonological processing for two purposes: (a) To investigate the basis of short-term memory deficits for children with reading disability, and (b) To further explore the origin of developmental verbal memory span increases.Using a variety of memory and phonological tasks, reading group comparisons were conducted testing third-grade good readers and poor readers, and developmental changes were studied with pre-kindergarten, first-grade and third-grade children. The main finding was that a strong relationship was observed between efficiency of phonological processes and capacity of verbal memory supporting the hypothesis that reducing phonological processing requirements in verbal short-term memory increases available resources for storage. No such relationship was found between phonological processing and nonverbal memory. This conclusion was supported by two findings: (a) The verbal short-term memory deficits in poor readers significantly correspond with less accurate phonological processing, and (b) Developmental increases in verbal STM are accompanied by more accurate and rapid execution of phonological tasks. 相似文献
