The direct, retention, and transfer effects of repeated word and pseudoword reading were studied in a pretest, training, posttest, retention design. First graders (48 good readers, 47 poor readers) read 25 CVC words and 25 CVC pseudowords in ten repeated word reading sessions, preceded and followed by a transfer task with a different set of items. Two weeks after training, trained items were assessed again in a retention test. Participants either received phonics feedback, in which each word was spelled out and repeated; word feedback, in which each word was repeated; or no feedback. During the training, both good and poor readers improved in accuracy and speed. The increase in speed was stronger for poor readers than for good readers. The good readers demonstrated a stronger increase for pseudowords than for words. This increase in speed was most prominent in the first four sessions. Two weeks after training, the levels of accuracy and speed were retained. Furthermore, transfer effects on speed were found for pseudowords in both groups of readers. Good readers performed most accurately during the training when they received no feedback while poor readers performed most accurately during the training with the help of phonics feedback. However, feedback did not differentiate for reading speed or for effects after the training. The effects of repeated word reading were found to be stronger for poor readers than for good readers. Moreover, these effects were found to be stronger for pseudowords than for words. This indicates that repeated word reading can be seen as an important trigger for the improvement of decoding skills. 相似文献

In two reading level design experiments, matched groups of normal and poor readers were compared with regard to their use of phonological and orthographic information. Experiment 1 used a semantic decision task similar to the task described in the study of Jarvella & Snodgrass (1974). Experiment 1 was aimed to assess the way normal and poor readers, matched on reading level, automatically process phonological and orthographic incongruencies when comparing the singular and plural of nouns. Experiment 2 investigated the automatized processing of uppercase-lowercase letter incongruencies in a same-different task using words and pseudowords. It assessed the role of letter feature cues involved in the initial identification process. Experiment 1 demonstrated that poor readers needed more time for evaluating phonologically incongruent word pairs. No independent effect of orthographic incongruency was found. Experiment 2 showed that, if compared with reading age matched normals, poor readers had more problems with evaluating uppercase-lowercase incongruencies. This orthographic processing problem was particularly prominent when pseudowords were presented. It is concluded that poor readers not only have phonological processing problems, but also have difficulties at the orthographic processing level. 相似文献

The performance of 38 male third- and fourth-grade reading disabled/poor decoders and above-average readers/good decoders was compared on a series of six measures of phonological awareness, including tasks that required the ability to segment, blend, and manipulate phonemes. Performance on these tasks was also correlated with phonetic decoding of pseudowords. Significant but varying intercorrelations were obtained among tasks in both groups. For the poor decoders, deletion was the most highly correlated with the other tasks. However, all good decoders performed at ceiling level on this task. For the poor decoders, deletion was significantly correlated with phonetic decoding (r = .74 and r = .78 for timed and untimed decoding measures, respectively). While all good decoders had good phonological awareness, not all those with good phonological awareness were good decoders. The results suggest that tasks that require blending and manipulation of phonemes, in addition to segmentation, may predict decoding ability best. 相似文献

The effect of two training procedures on the improvement of reading accuracy in poor readers was examined in relation to their initial reading level. A randomized controlled trial was conducted with 60 poor readers. Poor readers were assigned to a control group that received no training, or one of two training conditions. One training concentrated on the words the children read correctly (successes), the other on the words they read incorrectly (failures). They repeatedly read bisyllabic Dutch words, half of the training words involving context-sensitive spelling rules (vowel degemination or consonant gemination). Some children repeatedly read their successes, others their failures. The training used a computerized flashcards format. The exposure duration of the words was varied to maintain the accuracy rate at a constant level. In general, children who received training improved their reading accuracy and reading speed of trained words, and reading accuracy of untrained words, more than the control group. Which training focus is superior, depends on the reading level of the child and the type of words used. For children with a low initial reading level, to improve reading accuracy of bisyllabic words that follow context-sensitive spelling rules, a training focus on failures was superior over a training focus on successes. For children with a high initial reading level, improvement of reading speed was largest in a training on successes. Evidently, the improvement of word reading skills depends both on the children’s level of reading competence and on the type of training. 相似文献

This study investigated qualitative differences in poor readers relative to normally achieving readers of the same reading level. Thirty-eight 9-year-old poor readers and forty 7- and 8-year-old reading-age-matched normally achieving readers from the United Kingdom were matched in phonemic processing and then given tests of memory span and visual discrimination of letter-like characters, were required to read different word types (regular, exception, and pseudoword), and were asked to complete a homophonic pseudoword test. The poor readers were worse at reading pseudowords compared to the controls, but this difference was unrelated to phonemic length of number of letters, or to the ease of producing analogies for the pseudowords. The results suggest that although there are no differences with reading-age controls in phonological processing, poor readers have worse grapheme-phoneme conversion skills and greater reluctance to relinquish the lexical route when appropriate. The results also showed that poor readers were slightly better at visual discrimination but had poorer memory spans. 相似文献

The study evaluated the effect of repeated reading on reading speed among 36 Finnish-speaking poor readers in Grades 4 to 6. A switching replications design was applied: Group A (n = 20) received training first, and during this period Group B (n = 16) acted as a control group. After a midpoint test, the design was switched. The training material consisted of syllables, which were practiced during 10 training sessions for a total of 50 times. The reading speed of the trained syllables increased more during training than during the control period. During training, the reading speed of pseudowords containing the trained syllables improved significantly. This improvement was found both in a computer task and in a list-reading task, which had a lower congruency with the training method than the computer task. Finally, training did not induce changes in a control (text reading) task that assessed general reading speed. 相似文献

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

Interventions combining phonically based reading instruction with phonological training are generally effective for children with reading (decoding) difficulties. However, a minority of children respond poorly to such interventions. This study explored the characteristics of children who showed poor response to reading intervention and aimed to improve their literacy and language skills via a new theoretically motivated intervention. Twelve 8‐year‐old treatment poor responders with severe and persisting reading difficulties participated. A 9‐week reading intervention incorporating reading, phonological and vocabulary training was implemented. Before the intervention began the children showed almost no progress over 6 months of regular classroom education, on measures of oral language and literacy. Over the intervention period improvements were made on measures of reading, phonological awareness and language skills, which were maintained 6 months later. Although the intervention was effective, it should be noted that most children remained poor readers and require ongoing remediation. 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

Two studies of second graders at risk for reading disability, which were guided by levels of language and functional reading system theory, focused on reading comprehension in this population. In Study 1 (n = 96), confirmatory factor analysis of five comprehension measures loaded on one factor in both fall and spring of second grade. Phonological decoding predicted accuracy of real-word reading; automatic letter naming predicted rate of real-word reading; accuracy and rate of both real-word reading (more so than decoding of pseudowords) and text reading predicted reading comprehension; and Verbal IQ also predicted reading comprehension. In Study 2 (n = 98), the treatment group (before/after school clubs receiving an integrated instructional approach that was supplementary to the general reading program) improved significantly more in phonological decoding and state standards for reading fluency than the control group (general reading program that had some code instruction but emphasized comprehension). The rate of phonological decoding explained 60.3% of real-word reading. Both treatment and control children improved significantly in reading comprehension, but controlling for pretreatment individual differences in oral vocabulary or in phonological decoding eliminated this effect. Taken together, the results of the two studies support two paths to reading comprehension: one from vocabulary and verbal reasoning, and one from written language that has multiple links between subskills: (a) alphabetic principle --> phonological decoding, (b) automatic phonological decoding --> accurate real-word reading, (c) automatic letter coding ---> automatic word reading, and (d) automatic word reading --> fluent text reading. Instructional implications of both paths and the links within the written language are discussed. 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

In this paper we present an overview of a computer program directed toward the remediation of children's deficits in word recognition and phonological decoding. In the present studies, 138 children read stories on the computer, in their school, for a half hour per day during a semester. Children were trained to request synthetic-speech feedback (DECtalk) for difficult words by targeting the words with a mouse. Different groups received whole-word feedback, wherein targeted words were highlighted and spoken as a unit, or segmented feedback, wherein segments of words (onsets, rimes, or syllables) were sequentially highlighted and spoken by the computer, requiring the child to pay attention to and blend the segments. Both whole-word and segmented feedback resulted in almost twice the gains in standardized word recognition scores compared to control groups that spent an equal time in their normal remedial reading program. Most important, the computer-trained groups improved their phonological decoding of nonwords at about four times the rate of the control group. However, there was a significant interaction between level of deficit severity and optimal feedback condition. The most severely disabled readers showed the largest phonological decoding gains from syllable feedback, while the largest gains for the less severely disabled readers were from onset-rime feedback. The disabled readers' level of phonological awareness at pre-test was the strongest predictor for gains in word recognition and phonological decoding. Implications of the results for future training programs are discussed. 相似文献

We used structural equation modeling to investigate sources of individual differences in oral reading fluency in a transparent orthography, Russian. Phonological processing, orthographic processing, and rapid automatized naming were used as independent variables, each derived from a combination of two scores: phonological awareness and pseudoword repetition, spelling and orthographic choice, and rapid serial naming of letters and digits, respectively. The contribution of these to oral text-reading fluency was evaluated as a direct relationship and via two mediators, decoding accuracy and unitized reading, measured with a single-word oral reading test. The participants were “good” and “poor” readers, i.e., those with reading skills above the 90th and below the 10th percentiles (n = 1344, grades 2–6, St. Petersburg, Russia). In both groups, orthographic processing skills significantly contributed to fluency and unitized reading, but not to decoding accuracy. Phonological processing skills did not contribute directly to reading fluency in either group, while contributing to decoding accuracy and, to a lesser extent, to unitized reading. With respect to the roles of decoding accuracy and unitized reading, the results for good and poor readers diverged: in good readers, unitized reading, but not decoding accuracy, was significantly related to reading fluency. For poor readers, decoding accuracy (measured as pseudoword decoding) was related to reading fluency, but unitized reading was not. These results underscore the importance of orthographic skills for reading fluency even in an orthography with consistent phonology-to-orthography correspondences. They also point to a qualitative difference in the reading strategies of good and poor readers. 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 effect of two training procedures on the development of reading speed in poor readers is examined. One training concentrates on the words the children read correctly (successes), the other on the words they read incorrectly (failures). Children were either informed or not informed about the training focus. A randomized controlled trial was conducted with 79 poor readers. They repeatedly read regularly spelled Dutch consonant?Cvowel?Cconsonant words, some children their successes, others their failures. The training used a computerized flashcards format. The exposure duration of the words was varied to maintain an accuracy rate at a constant level. Reading speed improved and transferred to untrained, orthographically more complex words. These transfer effects were characterized by an Aptitude-Treatment Interaction. Poor readers with a low initial reading level improved most in the training focused on successes. For poor readers with a high initial reading level, however, it appeared to be more profitable to practice with their failures. Informing students about the focus of the training positively affected training: The exposure duration needed for children informed about the focus of the training decreased more than for children who were not informed. This study suggests that neither of the two interventions is superior to the other in general. Rather, the improvement of general reading speed in a transparent orthography is closely related to both the children??s initial reading level and the type of words they practice with: common and familiar words when training their successes and uncommon and less familiar words with training their failures. 相似文献

One explanation for the relationship between serial rapid naming (SRN) and reading is that SRN affects the temporal proximity
of the phonological activation of the letters in a word, which, in turn, influences the acquisition of orthographic knowledge.
To test this hypothesis, a group of Dutch first grade children was trained in the rapid serial naming of letter sounds. In
addition, a no-training control group and a serial addition training group were included. Various measures of SRN and of reading
were administered to evaluate the effect of the training. Before the training, we found a symbol-specific relationship between
SRN and reading: the relationship of reading with letter-sound naming was higher than its relationship with number naming.
The training of serial letter-sound naming was not successful. In contrast, the serial addition training was highly effective.
We conclude that it might be difficult to quickly improve the serial rapid naming of letter sounds in beginning readers. 相似文献

The purpose of this project was to examine group- and individual-level responses by struggling adolescents readers (6th–8th grades; N = 155) to three different modalities of the same reading program, Reading Achievement Multi-Component Program. The three modalities differ in the combination of reading components (phonological decoding, spelling, fluency, comprehension) that are taught and their organization. Latent change scores were used to examine changes in phonological decoding, fluency, and comprehension for each modality at the group level. In addition, individual students were classified as gainers versus non-gainers (a reading level increase of a year or more vs. less than 1 year) so that characteristics of gainers and differential sensitivity to instructional modality could be investigated. Findings from both group and individual analyses indicated that reading outcomes were related to modalities of reading instruction. Furthermore, differences in reading gains were seen between students who began treatment with higher reading scores than those with lower reading scores; dependent on modality of treatment. Results, examining group and individual analyses similarities and differences, and the effect the different modalities have on reading outcomes for older struggling readers will be discussed. 相似文献

This study explores early stages of reading acquisition, specifically therelation of phoneme blending and letter recoding to individual differencesin word decoding. The hypothesis was that facility in letter recoding andaccuracy of phoneme blending are substantial components of word decodingin beginning readers but not for skilled reading and that reliance onphoneme-sized decoding of words would dissipate as reading proficiencyincreased. In four studies we examined the ability to recode letters, blendphonemes and decode words in four groups of Dutch children (early Grade1, N = 130, older Grade 1, N = 81, Grade 3, N = 54 and a group of children witha reading lag, N = 356). Phoneme blending was only related to the readingability of beginning Grade 1 children. By the end of Grade 1 ability to blendphonemes did not differentiate reading capacity, nor for older children inGrade 3 and reading disabled children. Letter recoding was related to worddecoding in all four studies, although the strength of that relation diddwindle as reading skill level increased. The results of the study appearconsistent with self teaching hypothesis and other theories that imply atransient role of explicit phonological recoding in word identification. 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

The double-deficit hypothesis acknowledges both phonological processing deficits and serial naming speed deficits as two dimensions associated with reading disabilities. The purpose of this study was to examine these two dimensions of reading as they were related to the reading skills of 29 Spanish average readers and poor readers (mean age 9 years 7 months) who met the criteria for either single phonological deficit (PD), double deficit (DD), or no deficit. DD children were the slowest readers and had the weakest orthography processing skills. No significant differences were found between PD and DD groups on word and pseudoword reading. Word reading and reading comprehension skills were average or above average in the three studied groups. As in previous studies in transparent orthographies, word reading was not a salient problem for Spanish poor readers, whereas for the DD group, reading speed and orthographic recognition skills were significantly affected. 相似文献
