This paper investigates the relationship between phonological processing and reading ability amongst grade 4 and grade 5 Arabic
speaking children in Egypt. In addition to measuring reading level, the study assessed the children’s ability to identify
rhymes, delete individual phonemes from words, retain and manipulate sequences of digit names and rapidly access verbal labels.
Further literacy and literacy-related tasks required children to decode novel letter strings, to distinguish similar words,
to identify words within letter chains and to correctly spell dictated text. A non-verbal ability measure was also included
to allow comparisons to be made between a group of poor readers with good non-verbal skills (dyslexics) with a control group
of chronological-age-matched normal readers with equivalent average scores on the non-verbal task. Results indicated relationships
between literacy ability, decoding and phonological processing within this cohort, as well as identifying differences between
dyslexic and control groups that suggest Arabic dyslexics show signs of poor phonological skills. The study supports the view
that Arabic dyslexic children have impairments in the phonological processing domain. 相似文献

Repetition priming was used to examine whether children with dyslexia bias a lexical–semantic pathway when reading words aloud. For the dyslexic group (n = 18, age 9.4–11.8 years), but not for age‐matched controls (n = 18, age 9.2–12.4 years), reaction times when naming pictures were faster after naming the corresponding word. A reading age‐matched control group (n = 24, age 6.8–8.9 years) showed similar priming effects to the children with dyslexia. The magnitude of repetition priming was greater for children with dyslexia with poor nonword reading and slower picture naming. Assuming repetition priming of picture naming is contingent on accessing lexical phonology via semantics, the results suggest less‐skilled normal and disordered readers show a stronger bias towards a lexical– semantic pathway during word reading than skilled readers, and the severity of the phonological representations deficit modulates the strength of that bias in children with dyslexia. 相似文献

Parents of dyslexic children encounter many difficulties in understanding and accepting their children’s disability. This
affects the child’s self-image and the way s/he copes (Hallahan and Kauffman 1991; Einat 2003). The goal of this study was to develop VR immersive simulated states. The simulation was designed to help the parents of
dyslexic children experience the kind of errors their children make when reading. Two groups of parents of dyslexic children
participated in this experiment, an experimental group (N = 37), which experienced ten 3D worlds simulating different kinds of reading errors, and a control group (N = 30), that watched a movie describing and explaining similar errors. All the subjects were administered a cognitive questionnaire
(Shavit 2005) before and after the intervention. In addition, the participants in the experimental group were interviewed before and after
the intervention. The results indicate that experiencing a variety of simulated types of dyslexia with virtual reality can
bring about improvement in parents’ awareness of the dyslexic child’s cognitive experiences, and that this improvement is
significantly greater than that achieved by watching a film about dyslexia. 相似文献

Phonological and lexical characteristics of 30-month-old children’s spontaneous language samples were examined as indicators
of later reading outcome. Participants were 27 children, 10 children with reading disability and 17 children without reading
disability. Of the non-disabled readers, 7 were at high familial risk for reading disability, and 10 came from families with
no history of reading difficulties. Children later identified as reading disabled at second grade and beyond demonstrated
narrower lexical diversity and simpler phonological forms as compared to the normal reading participants. Implications of
reduced phonological complexity in the productive lexicons of reading disabled children are discussed. 相似文献

There is a consensus that dyslexia is on a continuum with normal reading skill and that dyslexics fall at the low end of the
normal range in phonological skills. However, there is still substantial variability in phonological skill among dyslexic
children. Recent studies have focused on the high end of the continuum of phonological skills in dyslexics, identifying a
“surface” dyslexic, or “delayed” profile in which phonological skills are not out of line with other aspects of word recognition.
The present study extended this work to a longitudinal context, and explored differences among subgroups of dyslexics on a
battery of component reading skills. Third grade dyslexics (n=72) were classified into two subgroups, phonological dyslexics and delayed dyslexics, based on comparisons to younger normal
readers at the same reading level (RL group). The children were tested at two points (in third and fourth grade). The results
revealed that the classification of dyslexics produced reliable, stable, and valid groups. About 82 percent of the children
remained in the same subgroup category when retested a year later. Phonological dyslexics were lower in phoneme awareness
and expressive language. Delayed dyslexics tended to be slower at processing printed letters and words but not at rapid automatic
naming of letters, and relied more heavily on phonological recoding in reading for meaning than did phonological dyslexics.
A subset of the delayed dyslexics with the traditional “surface dyslexic” pattern (relatively high pseudoword and low exception
word reading) was also identified. The surface subgroup resembled the RL group on most measures and was not very stable over
one year. The results are discussed in light of current models of dyslexia and recent subgrouping schemes, including the Double-Deficit
Hypothesis. 相似文献

Phonological processing skills and deficits in adult dyslexics 总被引:13,自引:0,他引:13
This article presents 4 experiments aimed at defining the primary underlying phonological processing deficit(s) in adult dyslexia. 5 phonological processes, all involving spoken language, were studied: phoneme perception, phoneme awareness, lexical retrieval of phonology, articulatory speed, and phonetic coding in verbal short-term memory. 2 differently ascertained adult dyslexic groups, familial dyslexics (n = 15) and clinic dyslexics (n = 15), were the subjects in each experiment. These dyslexic groups were chosen because deficits that persist until adulthood and that are found in differently ascertained dyslexic groups are more likely to be primary. Each dyslexic group was compared to 2 control groups, chronological age (CA) controls who were similar in age and sex, and younger reading age (RA) controls who were similar in reading age and sex. The main finding was a clear deficit in phoneme awareness in both dyslexic groups, with each dyslexic group performing significantly worse than both CA and RA controls. Moreover, performance on the 2 phoneme awareness tasks together uniquely accounted for substantial variance in nonword reading. The clinic but not the familial dyslexics appeared to have an additional deficit in verbal short-term memory. No clear deficits were found in either dyslexic group in phoneme perception, lexical retrieval, or articulatory speed. 相似文献

There are not enough reading tests standardized on adults who have very low literacy skills, and therefore tests standardized
on children are frequently administered. This study addressed the complexities and problems of using a test normed on children
to measure the reading comprehension skills of 193 adults who read at approximately third through fifth grade reading grade
equivalency levels. Findings are reported from an analysis of the administration of Form A of the Gray Oral Reading Tests—Fourth
Edition (Wiederholt & Bryant, 2001a, b). Results indicated that educators and researchers should be very cautious when interpreting test results of adults who have
difficulty reading when children’s norm-referenced tests are administered. 相似文献

The main objective of the present study was to examine the contribution of phonological and orthographic skills to Persian
reading and spelling. The Persian language is of interest because it has very consistent grapheme-to-phoneme correspondences,
but somewhat inconsistent phoneme-to-grapheme correspondences. Reading, spelling, phonological, and orthographic skills were
tested in a sample of 109 monolingual Persian students (mean age = 8;1, SD = 4 mo) attending Grade 2 in Iran. The results
showed that although monolingual Persian children relied both on phonological and orthographic skills, phonological skills
were a strong predictor for both reading and spelling. Another objective of the study was to compare children’s spelling performance
in terms of phoneme-to-grapheme (PG) consistencies. As expected, children spelled PG-consistent words more accurately than
PG-inconsistent words. Moreover, they relied more on orthographic skills for spelling PG-inconsistent words than for spelling
PG-consistent words. The results are discussed in terms of the differential effect of orthographic consistency on reading
and spelling. 相似文献

The effects of reading a CD-ROM storybook on children’s early literacy were examined as a function of their age group and
the number of times they used the software. The investigation was carried out on 214 children: 108 pre-kindergarten children
(aged 4:2 to 5:3) and 106 kindergarten children (aged 5:3–6:4). This population included 107 girls and 107 boys. The children
in each group were randomly assigned to one of three groups. The first intervention group was afforded three CD-ROM storybook
reading sessions. The second group was afforded five reading sessions and the third group served as a control and was afforded
the regular kindergarten program. Pre- and post-intervention early literacy measures included vocabulary, word recognition
and phonological awareness. No age group differences were found between the children’s early literacy progress after using
the software and no interaction was found between age group and the number of reading sessions. Children from both age groups
exhibited a similar level of story comprehension. Children who used the software five times exhibited greater progress in
word meaning than those who used it three times and children in both of these groups did better than the control group. Children
who used the software five times exhibited greater progress in word reading and phonological awareness than children in the
control group. Implications for future research and education are discussed. 相似文献

The present study retrospectively examined early difficulties with phonological coding and phonemic segmentation of German children who after four years in school were diagnosed as dyslexic. German, in comparison to English, exhibits rather simple and straight-forward grapheme-phoneme correspondences, and the initial teaching approach was phonics oriented. Despite these favorable circumstances for the acquisition of phonological coding, the majority of the later dyslexic children had particular difficulties with the accurate reading of nonwords and of unfamiliar words after about seven months of reading instruction. However, there were enormous differences between the dyslexic children. Two of them were completely unable to blend phonemes into pronunciations, another seven were slow and error prone decoders, and three children had slow and laborious pronunciation assembly as the core problem. The majority of the later dyslexic children also exhibited phonemic segmentation deficits as tested with a nonword spelling task and a phoneme reversal task. In correspondence with findings from older German dyslexic children, the early difficulties with accurate phonological coding and phonemic segmentation were no longer found at the end of grade four. Children then suffered from very slow reading and poor spelling. In general, the difficulties of German dyslexic children emphasize the phonological impairment account of dyslexia. More specifically, these findings suggest that the assembly of letter sounds into pronunciations is particularly affected in the early phase of learning to read a consistent orthography. 相似文献

Three experiments investigated the effects of rime consistency on reading and spelling among developing readers ranging in
age from 7 to 11 years. Experiment 1 found that children read words with inconsistent feedforward mappings between orthography
and phonology (O → P) less accurately than consistent words. OP consistency interacted with chronological age, word frequency
and age-of-acquisition (AoA). The effect of OP consistency on reading was larger for younger children than for older children
and OP consistency had an effect for low frequency words and late-acquired words only. Experiment 2 found an effect of feedforward
consistency between phonology and orthography (P → O) on children’s spelling but no interaction between PO consistency and
AoA. Experiment 3 showed that the effects of feedforward consistency are independent of feedback consistency. Our results
challenge models of reading and spelling that assume feedforward consistency effects are influenced by the frequency of exposure
to words only and we suggest that interactions between consistency and AoA depends on the ratio of consistent to inconsistent
OP mappings. 相似文献

The purpose of the present study was to examine the predictive value of a dynamic test of English and French lexical specificity on at-risk reading classification in 13 at-risk and 44 not at-risk emerging English (L1)–French (L2) bilingual Grade 1 children (M = 75.87 months, SD = 3.18) enrolled in an early French immersion program in Canada. Lexical specificity was assessed with a computerized word learning game in which children were taught new English (e.g., “foal” and “sole”) and French (e.g., bac “bin” and bague “ring”) word pairs contrasted by minimal phonological differences. The results indicated that the dynamic test of lexical specificity in English contributed significantly to the prediction of children’s French at-risk reading status at the end of Grade 1 after controlling for French phonological awareness and nonverbal reasoning skills. However, French lexical specificity did not predict children’s reading risk classification in French after controlling for French phonological awareness. Thus, it may be feasible to identify at-risk status in emerging bilinguals using dynamic measures in their stronger language. 相似文献

This paper presents the results of a follow‐up study of reading difficulties among Spanish‐speaking Latin American children of low socioeconomic background (SES) over four school years. The research started with a group of 93 children with reading difficulties (RD) by 2nd and 3rd grade teachers in four schools and a control group of 63 children without reading difficulties (ND), belonging to the same schools. Both groups were equivalent in age, grade, gender and SES. All children were tested on reading decoding and comprehension, reading and writing pseudo‐words, verbal abilities, visual perception, phonological processing, and the WISC‐R. Neither SES nor IQ accounted significantly for the reading difficulties in the RD group. The most predictive variables of the final reading level in the RD group were phonological processing, verbal abilities, and the initial level of decoding. After four years, 17% of the initial RD children had reached an average level of reading, but 11% of this group remained with severe reading difficulties and may be considered as dyslexic children. The RD children who became average readers were not significantly different from the control group in verbal abilities, nor in phonological processing. Nevertheless, they were significantly different in terms of IQ scores. The neuropsychological characteristics of the children with severe reading difficulties appear similar to those found in children with dyslexia in more developed countries. 相似文献

This study examined the extent to which observed teaching practices and self-reported teacher stress predict children’s learning
motivation and phonological awareness in kindergarten. The pre-reading skills of 1,268 children were measured at the beginning
of their kindergarten year. Their learning motivation and phonological awareness were assessed in the following spring. Questionnaires
measuring teacher stress were filled out by 137 kindergarten teachers. A pair of trained observers used the Classroom Assessment
Scoring System (Pianta et al. 2008) to observe 49 kindergarten teachers from the whole sample on their emotional support, classroom organization, and instructional
support. The results of multilevel modeling showed that low teacher stress and high classroom organization predicted high
learning motivation in children and that the children’s learning motivation contributed to their level of phonological awareness.
Moreover, children’s learning motivation mediated the association between teacher stress and children’s phonological awareness.
The results emphasize the importance of teachers’ pedagogical well-being and classroom organizational quality for children’s
learning motivation. 相似文献

The question posed in the current study is whether software alone is a sufficient tool for supporting young children’s emergent
writing. We researched the effect of reading an electronic book (e-book) on kindergarten children’s emergent word writing
with and without adult support. Ninety-six 5 to 6 years old children from low socioeconomic status (SES) families were randomly
assigned to one of three groups (32 children each): (1) independently reading the e-book; (2) reading the e-book with adult
support; (3) receiving the regular kindergarten program (control). Each intervention group received four e-book reading sessions.
The children’s emergent literacy was assessed before and after the intervention and included letter-name recognition, phonological
awareness and emergent word writing. Reading the e-book with adult assistance supported the children’s phonological awareness
and emergent word writing more significantly than reading the e-book without support and more than the control group. Reading
the e-book without adult support did not differ from the control group. Furthermore, the children’s initial emergent literacy
level and reading the ebook with adult assistance contributed the most to the children’s emergent word writing. Educational
implications are discussed. 相似文献

Representing written vowels in university students with dyslexia compared with normal hebrew readers
The study investigates dyslexic and normal Hebrew readers’ perception of words containing a vowel letter in different orthographic
and morphological contexts. In the first experiment, 72 undergraduate education students (half diagnosed with reading disabilities
and half normal readers) were asked to judge pointed words with different morphological structures with and without the grapheme
W. Half of the words had consistent (obligatory) W and half had inconsistent (optional) W. In the second experiment, the same
procedure was repeated using the same words without pointing marks. Response latencies and accuracy were measured. In both
experiments, dyslexic readers did less well than normal readers. They had lower scores on accurate lexical decisions and they
took more time over these decisions. They also exhibited some deviant patterns, indicating that they cannot make use of orthographic
and morphological cues that are available to normal readers, especially in the pointed experiment. Processing pointed words
placed a heavier cognitive burden on the dyslexic readers. These findings are in line with other studies of adult dyslexic
reader/writers, and support a reading / spelling processing model, which claims that internal orthographic representations
of words are increasingly strengthened with each exposure during reading, but not all graphemes are strengthened equally.
The general implication is that the ambiguities that exist in the relationships between orthography, phonology, and morphology
underlie spelling knowledge, and are particularly difficult for dyslexic readers. 相似文献

The main hypotheses addressed in the research were (1) whether imprecision in the phonological representations of lexical
items underlies the impaired expressive naming abilities of disabled readers, and (2) whether weak verbal memory might mediate
the relationship between naming and reading skills. From samples of 93 first graders and 67 fourth graders, extreme groups
of good and poor readers were identified and compared on measures of receptive vocabulary, expressive naming, acceptability
judgments for variants of object names, imitation and correction of naming errors by another speaker, pseudoword repetition,
and long-term memory. Performance was generally better by older than younger students and by good than poor readers at each
age, with little interaction between grade and reader group. The results indicated that for both good and poor readers, imprecise
phonological knowledge, especially about long words, contributed to children’s difficulties on all naming tasks. Memory differences,
however, appeared to play only a minor role in explaining the strong association between naming and reading. 相似文献

An important element of learning to read and write at school is the ability to define word boundaries. Defining word boundaries
in text writing is not a straightforward task even for children who have mastered graphophonemic correspondences. In children’s
writing, unconventional word segmentation has been observed across a range of languages and contexts with more occurrences
of hyposegmentation (failure to separate two or more written words with a space) than hypersegmentation (written words are
split into more than one segment). However, it is still unclear how frequent these errors are and the relationships of these
written error patterns to the child’s development in oral language, spelling and reading remains relatively unexplored. To
address these issues, unconventional written lexical segmentations in Brazilian Portuguese children’s text production during
their first years at primary school (Year 1 to Year 3) were examined in relation to different cognitive and linguistic measures
and patterns of spelling errors. Results reveal that in Portuguese the establishment of word boundaries in written text is
not explained by visuospatial skills or limitations in processing resources (working memory). In contrast higher occurrences
of hyposegmentation patterns were associated with lower levels of reading, vocabulary, verbal ability and morphological awareness
whereas hypersegmentations were rarer and related to lower levels of reading and morphological awareness and typically only
occurred in the initial stages of learning to write (Year 1). Occurrences of hyposegmentations as well as hypersegmentations
were also related to spelling errors which reflected children’s poor phonological skills. 相似文献

Children’s skill at recoding graphemes to phonemes is widely understood as the driver of their progress in acquiring reading
vocabulary. This recoding skill is usually assessed by children’s reading of pseudowords (e.g., yeep) that represent “new words.” This study re-examined the extent to which pseudoword reading is, itself, influenced by orthographic
rimes (e.g., eep) of words of the child’s reading vocabulary, during the development of reading skill. In Study 1, children with word reading
levels of 6–10 years read matched pseudowords that do and do not share an orthographic rime with words of their reading vocabularies.
Study 2 was conducted to further examine such a comparison for children of the 6- to 8-year word reading levels. There was
a small and constant advantage of shared lexical orthographic rimes for children with reading levels 6–8 years but from 8
to 10 years that advantage increased significantly, as expected by Ehri’s phase account of word reading development. The pseudoword
reading of children learning to read English involves use of lexical orthographic components as well as context-free recoding
of graphemes to phonemes. This implies a qualification to the common interpretation of pseudoword reading as a measure of
context-free grapheme–phoneme recoding. Such a measure should use selected pseudowords that do not share orthographic rime
units or other multigrapheme components with words of the children’s reading vocabularies. 相似文献
