Fifteen Portuguese children with dyslexia, aged 9–11 years, were compared with reading and chronological age controls with
respect to five indicators related to the phonological deficit hypothesis: the effects of lexicality, regularity, and length,
implicit and explicit phonological awareness, and rapid naming. The comparison between groups indicates that Portuguese children
with dyslexia have a phonological impairment which is revealed by a developmental deficit in implicit phonological awareness
and irregular word reading (where younger reading level controls performed better than dyslexics) and by a developmental delay
in decoding ability and explicit phonological awareness (where dyslexics matched reading level controls). These results are
discussed in relation to the idea that European Portuguese is written in an orthography of intermediate depth. 相似文献

This study investigated the reading and reading-related skills of 15 French-speaking adults with dyslexia, whose performance
was compared with that of chronological-age controls (CA) and reading-level controls (RL). Experiment 1 assessed the efficiency
of their phonological reading-related skills (phonemic awareness, phonological short-term memory, and rapid automatic naming
(RAN)) and experiment 2 assessed the efficiency of their lexical and sublexical (or phonological) reading procedures (reading
aloud of pseudowords and irregular words of different lengths). Experiment 1 revealed that adults with dyslexia exhibited
lower phonological reading-related skills than CAs only, and were better than RL controls on the RAN. In experiment 2, as
compared with RL controls, only a deficit in the sublexical reading procedure was observed. The results of the second experiment
replicated observations from English-language studies but not those of the first experiment. Several hypotheses are discussed
to account for these results, including one related to the transparency of orthographic systems. 相似文献

The phonological-core variable-orthographic differences (PCVOD) model [van der Leij, & Morfidi (2006). Journal of Learning Disabilities, 39, 74–90] has been proposed as an explanation for the heterogeneity among dyslexic readers in their profiles of reading-related
subskills. The predictions of this model were investigated in a sample of 72 Dutch secondary school students (dyslexics and
controls). First, the PCVOD assumption was confirmed that phonological processing and orthographic competence are independent
contributors to the prediction of reading fluency and spelling. Among the phonological processing tasks, phonological recoding
explained substantial unique variance, but not phonemic awareness or rapid serial naming. Next, the dyslexic readers were
divided into two subgroups based on high (ORTH+) and low levels (ORTH−) of orthographic competence. Both subgroups performed below controls on all measures tapping phonological processing, reading
and spelling but the ORTH+ group performed as well as non-disabled controls on Dutch and English orthographic choice. As predicted by the model, there
were no differences between the subgroups on the tasks that depend on phonological processing, with or without reading. There
were differences on Dutch word reading fluency and spelling. Furthermore, the ORTH+ subgroup outperformed ORTH− on tasks demanding speeded word processing such as ‘flashed’ presentation. This finding was independent of lexicality (words
or pseudowords), language (Dutch or English) or response mode (lexical decision or typing), but restricted to silent reading.
This supports the view that the ORTH+ subgroup is better at identifying larger orthographic units. There was no indication of differences between the subgroups
in reading experience. Our data, therefore, support the PCVOD model.

This study aimed to identify predictors of single word spelling performance in children using a novel test containing regular words, irregular words and pseudowords. We assessed reading ability, letter-sound knowledge, phonological awareness (PA) and rapid automatised naming (RAN) in children aged 4–12 years (N = 641). Mixed model analyses with hierarchical nested data were conducted with Year_group (Yr R to Yr 6) included as a factor, PA and RAN as predictors, and reading and letter-sound knowledge as covariates. For irregular word spelling, PA and RAN were significant predictors, but the associations were dependent upon the year the children attended. Interestingly, for regular words and pseudowords PA was not significantly related. For pseudowords, only RAN was a significant predictor and only in Yr 2. We argue that a better understanding of spelling development can be achieved using tools that distinguish between regular and irregular words and pseudowords, as different processes seem to be associated with the different types of letter string across the variable levels of spelling experience. 相似文献

The aim of the study was to elucidate the nature and efficiency of the strategies that readers with phonological dyslexia
use for temporary retention of written words in Working Memory (WM). Data was gathered through a paradigm whereby participants
had to identify serially presented written (target) words from within larger word pools according to their presentation order,
with word pools containing code-specific distracter (CSD) words and non-code-specific distracter (NCSD) words. Analyses focused
on three aspects of performance: (1) false recognition of target words; (2) correct recognition of target words; and (3) retention
of word presentation order. Participants were readers with diagnosed phonological dyslexia (n = 20, mean grade level = 9.05 [0.89]) and a control group of regular readers (n = 25, mean grade level = 9.00 [0.76]). Results provide direct evidence that the dyslexic readers and the regular readers
used essentially different memory coding strategies for the temporary retention of written words, with the former predominantly
relying on a visual strategy and the latter on a phonological strategy. Findings further pinpointed a notably impoverished
ability of the dyslexic readers to retain word presentation order. The implication of these findings is discussed in relation
to theories predicting the acquisition and mastery of reading.

We investigated the initial development of reading and spelling in European Portuguese. First-graders, tested in February
and June, had to read and spell words and pseudowords. In February there were regularity and graphemic complexity effects,
indicating that these children relied on grapheme–phoneme conversion. The lexicality effect found in spelling, in June, suggest
that by the end of first grade these children had begun to construct an orthographic lexicon. However, lexical addressing
is not inconsistent with phonological mediation as regularization errors increased between the sessions. Additionally, the
previously reported similarity in global performance of Portuguese and French beginning readers may conceal processing differences
that are related to specific characteristics of the corresponding orthographic codes.

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

We assessed the reading and reading-related skills (phonemic awareness and phonological short-term memory) of deaf children fitted with cochlear implants (CI), either exposed to cued speech early (before 2 years old) (CS+) or never (CS-). Their performance was compared to that of 2 hearing control groups, 1 matched for reading level (RL), and 1 matched for chronological age (CA). Phonemic awareness and phonological short-term memory were assessed respectively through a phonemic similarity judgment task and through a word span task measuring phonological similarity effects. To assess the use of sublexical and lexical reading procedures, children read pseudowords and irregular words aloud. Results showed that cued speech improved performance on both the phonemic awareness and the reading tasks but not on the phonological short-term memory task. In phonemic awareness and reading, CS+ children obtained accuracy and rapidity scores similar to CA controls, whereas CS- children obtained lower scores than hearing controls. Nevertheless, in phonological short-term memory task, the phonological similarity effect of both CI groups was similar. Overall, these results support the use of cued speech to improve phonemic awareness and reading skills in CI children. 相似文献

In addition to reading difficulties, a significant proportion of developmental dyslexics have spelling problems, which persist into adulthood. Studies carried out in languages with opaque orthographies have found that dyslexics frequently make phonological substitutions when spelling and have difficulties in developing orthographic representations of irregular words. Those errors seem to derive from an excessive use of phonological codes when writing. Minimal research in Spanish (relatively transparent orthography) about the relationship between dyslexia and spelling difficulties has been carried out to date. In this study, 19 Spanish-speaking developmental dyslexics (from 7 to 11 years old) and 28 controls (from 6 to 11 years old, distributed in two groups, one matched for age and the other for reading level with the dyslexics) performed a dictation task of 80 stimuli with different levels of orthographic consistency, in order to discover the codes they use in the writing process. Results showed that Spanish children with dyslexia made significantly more spelling errors, especially among the ruled and irregular words. These findings are consistent with the idea that these children have difficulties in developing orthographic representations and use phonological codes more frequently than non-dyslexics, resulting in phonologically plausible errors when writing irregular words. These results have important implications for the treatment of spelling difficulties in children with dyslexia, highlighting the need to focus on the correct acquisition of grapheme-phoneme conversion rules as well as the development of appropriate orthographic representations. 相似文献

This study was intended to help clarify the nature of dyslexia in Spanish. A sample of 30 children, 8 to 16 years old, participated
in this study. Dyslexic children were compared to two control groups, a chronological age-matched control group and a reading
level-matched control group. Measures included nonword and pseudohomophone reading (phonological procedure), homophone choice
(orthographic procedure), and phonological awareness tasks (syllabic, intrasyllabic, and phonemic level). For each task, accuracy
(error percentage) and performance time were measured. Results showed a deficit in the dyslexic group on all the tasks, which
was more evident when time was considered. With the results consistent with studies in other transparent orthographies such
as Italian and German, speed problems seem to be more evident and relevant than accuracy problems in Spanish dyslexic children.

The role of compound awareness in Chinese children’s vocabulary acquisition and character reading 总被引：1，自引：0，他引：1
This study examined compound awareness in relation to Chinese children's vocabulary acquisition and character reading. Two
aspects of compound awareness were investigated: the ability to identify the head of a compound noun and the ability to construct
a new compound word from familiar morphemes. The compound awareness tasks, along with rapid automatized naming (RAN) and phonological
awareness tasks, were administered to 29 first graders and 30 second graders in Mainland China. Results show that (1) compound
awareness develops relatively early among Chinese children and improves with age, (2) compound awareness explains unique variance
in vocabulary and character reading, after controlling for age, RAN, and phonological awareness, and (3) the contribution
made by compound awareness to vocabulary is much larger than the contribution made by phonological awareness. These results
demonstrate that compound awareness plays a central role in Chinese children's literacy development, particularly in vocabulary
acquisition.

The rationale for the study was that if dyslexic and garden-variety poor readers differ in reading-related cognitive skills, there is justification for believing dyslexia to be a distinct entity. Subjects were 110 children aged 6 to 10 years, divided into groups of dyslexic poor readers varying in verbal IQ, garden-variety poor readers, and good readers. Findings suggest that there are valid grounds for believing that dyslexia is a separate entity from garden-variety poor reading, and that it is found among children at all verbal IQ levels. Poor phonological awareness and nonword reading, in relation to normal readers, were shared by dyslexic and garden-variety poor readers. Deficits unique to dyslexic poor readers were problems in both automatic visual recognition and phonological recoding of graphic stimuli. The study supports the phonological-core variable-difference model of Stanovich (1988) in that both dyslexic and garden-variety poor readers showed phonological processing deficits, but they were more extensive in dyslexics. 相似文献

The main purpose of this paper was to see whether dual-route models of spelling, developed within the context of opaque languages and supported mainly by the spelling patterns of acquired dysgraphics, could account for the misspellings of Spanish children of different educational levels. Sixty children (20 second, 20 fourth and 20 eighth graders) were dictated 216 verbal stimuli. Half of these stimuli were words and the other half were matched nonwords. The dependent variable was the number of errors made. Words were controlled for frequency, length and regularity. Results show that second graders rely heavily on phonological mediation with:
Eighth graders, on the other hand, show the complementary pattern of results and, consequently, seem to use a lexical strategy (via the graphemic output lexicon). The only deviant result in this group is a significant regularity effect, although the degree of this effect is smaller than in second graders. Fourth grade children show an intermediate pattern. A qualitative analysis (error types) also supports predictions made by the dual-route models. Some final considerations are proposed to explain the regularity effect in eighth graders and, based on the pattern of phonological errors, the possibility of a functional interdependence of both strategies of spelling. 相似文献

A flash card computer program designed to increase decoding speed in reading was evaluated with a sample of 55 eight- to twelve-year-old Dutch poor readers by using a pretest-training-posttest control group design. The reading level of the poor readers was comparable to the reading level of normal readers in grade two. After 8 weeks of practicing (twice a week) for 30 minutes per session, children in the training group showed substantial improvements in decoding speed not only on pseudowords directly practiced during the training, but also in untrained pseudowords and in existing words. The no-training control group did not improve in decoding speed from pre- to posttest. The results, furthermore, indicate that syllable-bound processes play a role in phonological decoding in Dutch, and that the flash card method used in this study stimulates poor readers to decode letter strings into syllabic units, which leads to an increase in decoding speed. The role of the syllable in phonological decoding and the potential of a specific flash card technique as a means to improve decoding skills of poor readers are discussed. 相似文献

This paper describes a 2-year longitudinal study of 76 initially prereading children. The study examined the relationships between phonological awareness (measured by tests of onset and rime, phonemic segmentation and phoneme deletion), verbal working memory and the development of reading and spelling. Factor analyses showed that the verbal working memory tests which were administered loaded on two distinct but highly related factors, the first of which,simple repetition, involved the repetition of verbal items exactly as spoken by the experimenter, whereas the second,backwards repetition, involved repetition of items in reverse order. Factor analyses also showed that, whist the phonological awareness variables consistently loaded on the backwards repetition factor at the beginning and end of Grade 1, by Grade 2 the phonological awareness variables loaded on a separate factor which also included sentence repetition. Results of multiple regression analyses, with reading and spelling as a compound criterion variable, indicated that phonological awareness consistently predicted later reading and spelling even when both simple and backwards repetition were controlled. In contrast, verbal working memory did not consistently predict reading and spelling across testing times. Whilst there was some indication that verbal working memory, especially backwards repetition, measured during Grade 1 did predict reading and spelling in Grade 2, these effects were no longer evident when all three phonological variables were controlled. Nevertheless, with 4 individual reading and 2 individual spelling measures as the criterion variables, it was shown that phonological awareness was not quite such a consistent predictor of reading and spelling: it was most highly related to reading pseudowords and spelling real words; but it was not so highly related to spelling pseudowords, apparently because the processing demands of the task for the young children in the study were extremely high. Given the importance of verbal working memory for the completion of phonological awareness, reading and spelling tasks, in particular for spelling pseudowords, the findings are interpreted as providing some support for a theoretical position which posits that both phonological awareness and verbal working memory contribute to the early stages of literacy acquisition. Whilst the findings suggest some support for a general underlying phonological ability, there is also evidence that, as children learn to read and write, verbal working memory and phonological awareness become more differentiated. 相似文献

Reading disability (RD) typically consists of deficits in word reading accuracy and/or reading comprehension. While it is
well known that word reading accuracy deficits lead to comprehension deficits (general reading disability, GRD), less is understood
about neuropsychological profiles of children who exhibit adequate word reading accuracy but nevertheless develop specific
reading comprehension deficits (S-RCD). Establishing the underlying neuropsychological processes associated with different
RD types is essential for ultimately understanding core neurobiological bases of reading comprehension. To this end, the present
study investigated isolated and contextual word fluency, oral language, and executive function on reading comprehension performance
in 56 9- to 14-year-old children [21 typically developing (TD), 18 GRD, and 17 S-RCD]. Results indicated that TD and S-RCD
participants read isolated words at a faster rate than participants with GRD; however, both RD groups had contextual word
fluency and oral language weaknesses. Additionally, S-RCD participants showed prominent weaknesses in executive function.
Implications for understanding the neuropsychological bases for reading comprehension are discussed.

This study examined (1) the potential influence of oral language characteristics of two languages that bilingual children
acquire on their PA and (2) the relationship of PA in L1 with PA and literacy skills in L2, using data from Korean–English
bilingual children. Thirty three Korean–English bilingual children, composed of two subsamples from two different locations/bilingual
programs, participated in the study. The findings showed that the sample of bilingual children from two bilingual programs
differed in their mean performances on intrasyllabic phonological awareness in Korean (i.e., rime awareness and body awareness).
Furthermore, children’s Korean rime awareness, but not body awareness, was positively related to their phonological awareness
and literacy skills in English. Finally, these children’s phonological awareness in Korean made a positive contribution to
English decoding skills even after controlling for their English sight word reading skills. The results are discussed in light
of interlingual influence on bilingual children’s phonological awareness.

This study examined the relationship between morphological awareness and reading comprehension in English among Spanish-speaking
English language learners (ELLs) followed from fourth through fifth grade. Students’ ability to decompose derived words while
reading was assessed using an experimental task. Multiple regression analyses were used to investigate the contribution of
performance on this task to reading comprehension above and beyond word reading skills, phonological awareness, and breadth
of vocabulary knowledge. The relationship between morphological awareness and reading comprehension was found to strengthen
between fourth and fifth grade, and in fifth grade, morphological awareness was found to be a significant predictor of reading
comprehension. The findings were robust across two measures of reading comprehension and two methods of scoring the experimental
task of morphological awareness, and thus support the inclusion of derivational morphology in a model of the English reading
comprehension of Spanish-speaking ELLs.

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
