This paper explores the relationship between speech and spelling in a single-case study of developmental dyslexia. JM, a developmental dyslexic with a well-documented history of speech, reading and spelling difficulties, was examined when he was 13–14 years old. He still had subtle articulation difficulties causing some disfluency and his use of phonetic voicing was atypical. We argue that these difficulties were recapitulated in his spelling where he was more sensitive to the prosodic aspects of words than normal spellers, exhibiting a strong tendency to spell accurately words which are stressed on the first, rather than the second syllable. He also had more difficulty with phonetic voicing and spelling errors reflected this uncertainty. Thus, when word-specific (orthographic) spelling information is unavailable, JM, like all spellers, must make use of phonological spelling strategies. In his case, these are compromised because of underlying phonological speech problems. It is argued that, while young children make use of a phonological frame on which to organize orthographic information, dyslexics, like JM, who have inadequate phonological representations, are unable to do so. This has a detrimental effect on their acquisition of spelling. 相似文献

The role of spelling recognition was examined in word reading skills and reading comprehension for dyslexic and nondyslexic children. Dyslexic and nondyslexic children were matched on their raw word reading proficiency. Relationships between spelling recognition and the following were examined for both groups of children: verbal ability, working memory, phonological measures, rapid naming, word reading, and reading comprehension. Children’s performance in spelling recognition was significantly associated with their skills in word reading and reading comprehension regardless of their reading disability status. Furthermore, spelling recognition contributed significant variance to reading comprehension for both dyslexic and nondyslexic children after the effects of phonological awareness, rapid naming, and word reading proficiency had been accounted for. The results support the role of spelling recognition in reading development for both groups of children and they are discussed using a componential reading fluency framework. 相似文献

Early interactive processes of development in reading, spelling and implicit and explicit phonological awareness were assessed in a group of children at four time-points as they progressed through their first three years in school. Exploratory causal path analyses were used to investigate the contribution of each ability to the subsequent growth of skill in reading, spelling and phonological awareness. The resultant structural models demonstrate a role of spelling in the early stages of reading acquisition, as well as differential contributions of implicit and explicit phonological awareness to both reading and spelling. They also suggest a developmental cascade from implicit to explicit phonemic awareness in the normal acquisition of phonological knowledge and associated skills. In the early formulative stages of reading implicit phonemic awareness and reading act reciprocally to build skill in each other. But, as ability in word recognition improves, implicit phonemic awareness plays a diminished role in reading. This pattern of initial reciprocal influence and later dissociation is repeated in the relationship between implicit phoneme awareness and spelling. Explicit phonemic awareness is an important factor in the first stages of spelling development but only emerges later as a significant contributor to reading. The early influence of explicit phoneme awareness on spelling, in conjunction with the major contribution of spelling to beginning reading, indicates that experience in spelling promotes the use of a phonological strategy in reading. Within a developmental context, explicit phoneme awareness initially appears to grow out of an implicit appreciation of the overall sound properties of words. Thereafter, ability to identify and segment phonemes develops independently of implicit phonemic awareness and plays an increasingly important role in the further growth of reading and spelling. 相似文献

This paper investigates Spanish dyslexic spelling abilities: specifically, the influence of syllabic linguistic structure (simple vs consonant cluster) on children's spelling performance. Consonant clusters are phonologically complex structures, so it was anticipated that there would be lower spelling performance for these syllabic structures than in simple ones, because of the poor phonological processing of dyslexic children. The participants were 31 dyslexic children, 31 chronological age‐matched children and 31 reading level‐matched children. A dictation task with words and pseudowords (with and without consonant clusters) was used. Word lexical frequency was controlled. The results show that the spelling of consonant clusters presents difficulties for dyslexic spelling performance despite this structure being orthographically consistent. Dyslexic children present a higher performance difference in items with consonant clusters than in simple items, compared with typically developing children. The work raises questions about the items used for the identification of dyslexic children's difficulties. 相似文献

A cohort of 92 children was followed through sixth grade to investigate the relationship of preschool skills and first grade
phonological awareness to reading and spelling. In particular, the focus was on the changing roles of letter naming, orthographic
awareness, and phonological processing in prediction, as reading experience increased. Preschool letter naming was a consistently
significant predictor of reading vocabulary, reading comprehension, and spelling at each grade level, but the preschool orthographic
task contributed most to reading comprehension and spelling at the higher grades. Conversely, the contribution of the first
grade phonemic awareness measures to reading skills dropped sharply after third grade, although they continued to contribute
to spelling prediction. When preschool precursors of phonological processing were examined, letter naming was found to be
a predictor of first and third grade phonemic awareness. Findings confirm the importance of letter naming as a predictor and
of the role of phonemic awareness in early reading acquisition, but also highlight the contribution of orthographic processing
skills to later reading. 相似文献

The present study was designed to investigate the influence of syntactic complexity on sentence comprehension in Hebrew. Participants were 40 native Hebrew-speaking 5th grade dyslexic and normally reading children aged 10–11 years. Childrens syntactic abilities were tested by three experimental measures: syntactic judgment, a sentence-picture matching task, and a sentence correction task. Each task consisted of sentences composed of five syntactic constructions varying in the level of syntactic complexity (active, passive, conjoined, object-subject relative, and subject-object relative). The length of sentences and the number of propositions in the sentences were controlled. In addition, a wide range of the childrens reading and general abilities (e.g., reading comprehension, phonological awareness, and working memory) was examined. The results indicated that dyslexic readers were less accurate and slower than good readers in all reading tasks and in the tasks on sentence comprehension. The findings suggest that the factor of syntactic complexity seems to be a relatively independent aspect of sentence comprehension. This aspect of sentence comprehension is probably not affected in dyslexic readers. Rather, processing deficit related to phonological and memory impairments of dyslexic children and their ability to process syntactic information is responsible for the difficulties in sentence comprehension. 相似文献

In this paper we apply a developmental model of reading to the question of dyslexic subtypes. Groups of normal readers (n=40)
and dyslexic children (n=50), matched on reading level and IQ, were given a comprehensive test battery measuring level of
development of visual, phonological, and orthographic skills. As a group, dyslexics deviated from normal readers of equivalent
reading achievement primarily in phonological skills (spelling-to-sound translation and phonemic analysis), although limited
differences in knowledge of word-specific spellings were also observed. Dyslexics were superior to the younger normal readers
in visual processing of print. Analysis of individual data by reference to the reading level control group revealed three
major subgroups: a group with a specific deficit in phonological processing of print (52 percent), a group with deficits in
processing both the phonological and orthographic features of printed words (24 percent), and a group with phonological deficits
in language (8 percent). The remainder of the sample (16 percent) had specific deficits in visual or orthographic processing
of print, in spelling, or did not differ from the control group. The data support the view that most developmental dyslexics
have a specific language disorder involving some aspect of phonological processing. However, small subgroups with very different
configurations of reading and nonreading difficulties may exist as well.

Characteristics of spelling development and spelling error patterns were examined in 100 schoolchildren (aged 7 to 15 years)
previously identified as dyslexic with specific phonological weaknesses. Within a severely restricted range, spelling development
generally followed a normal course despite wide individual variation. The group was divided using two different spelling criteria:
(1) global spelling stage, and (2) a split based on the number of spelling confusions involving phonetically similar consonants.
Comparisons using either criterion led to the conclusion that better spellers are also better readers and are more skilled
in phoneme manipulation. Regression analyses suggested that measures of phonemic segmenting and manipulation make independent
contributions to the acquisition of word reading. Phoneme segmenting explained significant variance only when students were
subdivided according to errors in coding confusable consonants. Implications for instruction are considered. 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.

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

This study examined whether the characteristic reading speed impairment of German dyslexic children results from a general skill-automatization deficit sensu Nicolson and Fawcett (1990) or from more specific deficits in visual naming speed and phonological skills. The hypothesized skill-automatization deficit was assessed by balancing, peg moving, and visual search. Rapid "automatized" naming tasks served as measures of impaired visual naming speed, and the phonological deficit was assessed by speech perception, phonological sensitivity, and phonological memory tasks. Dyslexic German children and age-matched control children (all boys) were tested at the end of Grade 2 and as participants of a longitudinal study also at the beginning of Grade 1. No evidence for a skill-automatization deficit was found, as the dyslexic children did not differ at all on the balancing tasks and little on the other nonverbal skill tasks. However, the dyslexic children showed impaired visual naming speed and impaired phonological memory performance that were observed not only in Grade 2 but also before learning to read. Overall, the findings support the conclusion that, even in regular orthographies, difficulties in learning to read are due to a phonological deficit and not to a general skill-automatization deficit. 相似文献

Several researchers have shown that invented spelling activities in kindergarten foster preschool children’s early literacy skills. However, few studies have assessed its impact on learning to read and write in the first year of primary school. Our goal was to analyse the impact of an invented spelling programme with kindergarteners on their literacy skills until the end of Grade 1. A follow-up study was conducted with 45 five-year-old Portuguese children attending two classes of two schools in Lisbon. The teaching effect was controlled as children from each class were randomly assigned into two groups (experimental/control) — equivalent on letter knowledge, cognitive abilities and phonological awareness. The participants were assessed in kindergarten with a pre-test, immediate post-test and delayed post-test (spelling; reading; phonemic awareness) and at the end of Grade 1 (spelling; reading). The experimental group participated in invented spelling sessions, while control children participated in storytelling activities. Data analysis revealed statistically significant differences between the two groups. The experimental group scored higher, not only in kindergarten but also in the follow-up year for all literacy measures. 相似文献

In an opaque orthography like English, phonological coding errors are a prominent feature of dyslexia. In a transparent orthography like Spanish, reading difficulties are characterized by slower reading speed rather than reduced accuracy. In previous research, the reading speed deficit was revealed by asking children to read lists of words. However, speed in list reading sums the time required to prepare an utterance, reaction time (RT), with the time required to say it, response duration (RD). Thus, the dyslexic speed deficit in transparent orthographies could be driven by slow RTs, by slow RDs, or both. The distinction is especially important if developmental readers rely on phonological coding to achieve lexical access because the whole word would have to be encoded before it could be identified. However, while the factors that affect reading RT have been extensively investigated, no attention has been paid to RD. We studied the performance of typically developing and dyslexic Spanish children in an oral reading task. We analysed the impact of word frequency and length on reading accuracy, RT, and RD. We found that accuracy, RT, and RD were affected by word frequency and length for both control and dyslexic readers. We also observed interactions between effects of reader group—dyslexic, typically developing (TD) younger or TD older readers—and effects of lexicality, frequency, and word length. Our results show that children are capable of reading aloud using lexical and sub-lexical coding processes in a transparent orthography. 相似文献

This study examined the nature of the relationship between phonemic awareness and reading and spelling development and focused particularlyon the development of early self-directed writing. The spontaneous writing attempts of 44 first-graders were followed on 6 test occasions from the start of grade 1 (7 years) until the middle of grade 2. The children were divided into 2 groups, one group (N = 21) with a high level of phonemic awareness on entry into grade 1 (HPA) and one group (N = 23) with a low level on entry (LPA). The connection between level of inventedspelling used in the self-directed writing and later reading andspelling achievement in grades 1 and 2 was investigated. The results showed remarkable differences between the two groups. Level of invented spelling at Time 1 was highly predictive of both reading and spelling achievement at the end of grades 1 and 2, but only for the HPA group. With Time of Mastery regarding phonemic spelling as the independent variable and reading and spelling at the end of grade 2 as the dependent variable, regressions analysis indicated strong direct effects of early phonemic spelling upon later reading and spelling development, but only for the LPA children. The two groups showed different patterns of development in learning to read and spell during grades 1 and 2. 相似文献

The simultaneous auditory processing skills of 17 dyslexic children and 17 skilled readers were measured using a dichotic listening task. Results showed that the dyslexic children exhibited difficulties reporting syllabic material when presented simultaneously. As a measure of simultaneous visual processing, visual attention span skills were assessed in the dyslexic children. We presented the dyslexic children with a phonological short-term memory task and a phonemic awareness task to quantify their phonological skills. Visual attention spans correlated positively with individual scores obtained on the dichotic listening task while phonological skills did not correlate with either dichotic scores or visual attention span measures. Moreover, all the dyslexic children with a dichotic listening deficit showed a simultaneous visual processing deficit, and a substantial number of dyslexic children exhibited phonological processing deficits whether or not they exhibited low dichotic listening scores. These findings suggest that processing simultaneous auditory stimuli may be impaired in dyslexic children regardless of phonological processing difficulties and be linked to similar problems in the visual modality. 相似文献

The study evaluated a substantially updated version of Orton's (1937) classical idea of a significant relatonship in dyslexic children between cerebral lateralization and their word decoding deficits. Attentional lateralization was examined under the assumption that covert spatial attention when directed contralaterally interacts with ageinvariant cerebral asymmetries for receptive speech. Thirty dysphonetic dyslexic children were compared to 30 younger normal readers who were matched to the dyslexics in reading comprehension. The children were tested in left ear (LE) and right ear (RE) directed attention dichotic listening (DAD), and in pseudoword decoding, word recognition, reading comprehension, spelling, arithmetic, and in general intelligence (IQ). Group comparisons in DAD failed to show any differences, confirming the mounting evidence that dyslexia is not related to incomplete lateralization. Entering the DAD scores of the dyslexics (LE first, LE second, RE first, RE second) as predictors of achievement revealed that, independently of chronological age (CA) and IQ, their ability to recall items from the LE first produced a negative regression which predicted 42 percent of the variance in pseudoword decoding. Selective report from the LE also produced small but significant negative correlations with visual recognition of real words and spelling; but no relationship to reading comprehension. IQ was related to reading comprehension and to the ability to shift attention from the LE to the RE. Eventhough the dyslexics were lateralized normally, weak lateralization was related specifically to phonological word decoding, a core deficit in dyslexia. However, unlike Orton's concept, these findings suggest that dyslexics suffer from exuberant right hemisphere processing in response to spatial attentional demands that, in turn, interferes transcallosally with the development of the sound-symbol representations that are required for fluent reading. Lateralization, per se, is unaffected by the disorder. 相似文献

Children with dyslexia are believed to have very poor phonological skills for which they compensate, to some extent, through relatively well-developed knowledge of letter patterns. We tested this view in Study 1 by comparing 25 dyslexic children and 25 younger normal children, chosen so that both groups performed, on average, at a second-grade spelling level. Phonological skill was assessed using phoneme counting and nonword spelling tasks. Knowledge of legal and illegal letter patterns was tested using a spelling choice task. The dyslexic children and the younger nondyslexic children performed similarly on all the tasks, and they had difficulty, for the most part, with the same linguistic structures. Supporting the idea that older dyslexics spellings are quite similar to those of typical beginners, we found in Study 2 that experienced teachers could not differentiate between the two groups based on their spellings. 相似文献

In addition to an intrinsic difficulty in reading and spelling, one of the defining characteristics of dyslexia is an enduring and pervasive difficulty in phonological coding, such that dyslexic readers find it particularly challenging to process and manipulate the constituent sounds of a language. Coexistent with this finding is the evidence that some dyslexic readers also demonstrate subtle sensory coding problems in the visual and auditory domains. Few theories have been proposed to unite these different findings within a coherent model of reading. Here the evidence for visual, auditory and phonological coding problems in dyslexia is briefly reviewed, and a hypothesis is proposed for how adequate early sensory coding may be intrinsic to phonological awareness and subsequent reading ability. In this hypothesis, a cortical network is assumed that incorporates the visual, auditory and phonological skills of reading. The visual sub‐component of the network is mediated by the dorsal visual pathway, which is responsible for the accurate spatial encoding of letters, words and text. The auditory component of the network in pre‐readers is intrinsic to the development of phonological sensitivity, and then grapheme‐phoneme assimilation as reading skills develop. In this hypothesis, some of the symptoms of dyslexia may result from subtle problems in the encoding of both visual and auditory information and their role in maintaining the synchronicity of the reading network. 相似文献

Although phonemic awareness is a well-known factor predicting early reading development, there is also evidence that Rapid Automatized Naming (RAN) is an independent factor that contributes to early reading. The aim of this study is to examine phonemic awareness and RAN as predictors of reading speed, reading comprehension and spelling for children with reading difficulties. It also investigates a possible reciprocal relationship between RAN and reading skills, and the possibility of enhancing RAN by intervention. These issues are addressed by examining longitudinal data from a randomised reading intervention study carried out in Sweden for 9-year-old children with reading difficulties (N?=?112). The intervention comprised three main elements: training of phonics, reading comprehension strategies and reading speed. The analysis of the data was carried out using structural equation modelling. The results demonstrated that after controlling for autoregressive effects and non-verbal IQ, RAN predicts reading speed whereas phonemic awareness predicts reading comprehension and spelling. RAN was significantly enhanced by training and a reciprocal relationship between reading speed and RAN was found. These findings contribute to support the view that both phonemic awareness and RAN independently influence early phases of reading, and that both are possible to enhance by training. 相似文献
