Reading fluency is one of the basic processes of learning to read. Children begin to develop fluency when they are able to form orthographic representations of words, which provide direct, smooth, and fast reading. Dyslexic children of transparent orthographic systems are mainly characterized by poor reading fluency (Cuetos & Suárez-Coalla 2009; Spinelli, De Luca, Di Filippo, Mancini, Martelli, & Zoccolotti, 2005; Wimmer, 1993). Therefore, the main problem for these children could be the difficulty in developing orthographic representations of the words they read. The aim of this study was to test the ability of dyslexic Spanish-speaking children (whose native language is Spanish) to develop orthographic representations and determine if the context helps them. For this, two experiments were conducted with a group of 100 children, 7–12 years of age. The groups were comprised of 20 dyslexics, 40 chronological age-matched controls and 40 reading level-matched controls. In the first experiment, eight unfamiliar words (four short and four long) were presented six times within the context of a story. In the second experiment, eight pseudowords were presented on a computer and the children had to read them aloud. In both experiments, the reading and articulation times of experimental and control stimuli were compared, before and after the training. Children without dyslexia showed a decrease of the influence of length of word on reading speed, indicating a lexical reading, while for dyslexic children, the influence of length remained unchanged. These results appeared when the stimuli were presented in the context of a story as well as when presented in isolation. In short, our results describe that dyslexic children of transparent orthographic systems have problems in developing orthographic representations of words.  相似文献

This study examined word identification, phonological recoding efficiency, familiar word reading efficiency, orthographic choice for familiar words and serial naming speed as potential correlates of orthographic learning following silent reading in third‐grade children. Children silently read a series of short stories, each containing six repetitions of a different target non‐word. They subsequently read target non‐words faster than homophones and preferred target non‐words to homophones in an orthographic choice task, indicating that they had formed functional orthographic representations of the target non‐words through phonologically recoding them during silent story reading. Target non‐word orthographic choice was correlated with all measures bar non‐symbol naming speed. The association between phonological recoding efficiency and orthographic learning lends support to the hypothesis that self‐teaching occurs through phonological recoding even in silent reading. Our findings were not generally consistent with the view that serial naming speed assesses orthographic learning aptitude.  相似文献

Orthographic learning is one of the steps needed to achieve reading fluency. There are different variables that could influence the formation of orthographic representations. The aim of this study was to investigate the role of the previous semantic and phonological knowledge on the formation of orthographic representations. We used a decrease of the length effect as the measure of orthographic learning. We made a reading aloud task that utilised new words with Spanish children from third grade under three different conditions: with prior semantic and phonological training, with prior phonological training and without training. Results showed that knowing the meaning and the phonological form of the words facilitated the formation of orthographic representations, as the length effect was significantly lower than in the other conditions, and it also improved the children's reading performance.  相似文献

In this study the effect of repeated reading on the acquisition of orthographic knowledge was examined. Acquisition of orthographic knowledge was assessed by the effect of word length on reading speed. We predicted that the effect of length in a set of words and pseudowords would decrease after the repeated reading of these (pseudo)words. The study involved fourth and fifth grade dyslexic children, in addition to normal readers in second and fourth grade. Words and pseudowords ranged from four to six letters and were read 16 times. A length effect was found in the dyslexic and younger normal readers, but not in the older normal readers. The length effect did not change from pre‐test to post‐test, although a large overall improvement in reading speed was found in all groups. These results suggest that repeated reading did not alter the predominantly sub‐lexical reading procedure of the dyslexic and younger normal readers. Implications for the interpretation of the length effect and the notion of word‐specific orthographic knowledge are discussed.  相似文献

We combined independently the word length and word frequency to examine if the difficulty of reading material affects eye movements in readers of German, which has high orthographic regularity, comparing the outcome with previous findings available in other languages. Sixteen carefully selected German-speaking dyslexic children (mean age, 9.5 years) and 16 age-matched controls read aloud four lists, each comprising ten unrelated words. The lists varied orthogonally in word length and word frequency: high-frequency, short; high-frequency, long; low-frequency, short; low-frequency, long. Eye movements were measured using a scanning laser ophthalmoscope (SLO). In dyslexic children, fixation durations and the number of saccades increased both with word length and word frequency. The percentage of regressions was only increased for low-frequency words. Most of these effects were qualitatively similar in the two groups, but stronger in dyslexic children, pointing to a deficient higher-level word processing, especially phonological deficit. The results indicate that reading eye movements in German children are modulated by the degree of difficulty, and orthographic regularity of the language can determine the nature of modulation. The findings suggest that, similar to Italian but unlike English readers, German children prefer indirect sub-lexical strategy of grapheme-phoneme conversion.  相似文献

Spanish-speaking children learn to read words printed in a relatively transparent orthography. Variation in orthographic transparency may shape the architecture of the reading system and also the manifestation of reading difficulties. We tested normally developing children and children diagnosed with reading difficulties. Reading accuracy was high across experimental conditions. However, dyslexic children read more slowly than chronological age (CA)-matched controls, although, importantly, their reading times did not differ from those for ability-matched controls. Reading times were significantly affected by frequency, orthographic neighbourhood size and word length. We also found a number of significant interaction effects. The effect of length was significantly modulated by reading ability, frequency and neighbourhood. Our findings suggest that the reading development of dyslexic children in Spanish is delayed rather than deviant. From an early age, the salient characteristic of reading development is reading speed, and the latter is influenced by specific knowledge about words.  相似文献

The self‐teaching hypothesis suggests that knowledge about the orthographic structure of words is acquired incidentally during reading through phonological recoding. The current study assessed whether visual processing skills during reading further contribute to orthographic learning. French children were asked to read pseudowords. The whole pseudoword letter string was available at once for half of the targets while the pseudoword's sub‐lexical units were discovered in turn for the other half. Then memorisation of the targets’ orthographic form was assessed. Although most pseudowords were accurately decoded, target orthographic forms were recognised more often when the pseudowords entire orthographic sequence was available at once during the learning phase. The whole‐word presentation effect was significant and stable from third to fifth grades. This effect was affected neither by target reading accuracy nor by target reading speed during the learning phase. Results suggest that beyond recoding skills, the ability to process the entire orthographic letter string at once during reading contributes to efficient orthographic learning.  相似文献

Two randomised control experiments examined spelling outcomes in a repeated measures design (pre‐test, post‐tests; 1‐day, 1‐month follow‐up, 5‐month follow‐up), where students learned Spanish irregular words through (1) immediate feedback using self‐correction, (2) visual imagery where children imagine and represent words using movement, and (3) copying words. The two control groups engaged in reading and dictation. We expected that methods with kinesthetic components and segmentation of stimuli would yield better orthographic representations in memory. Results showed that orthographic errors on Spanish irregular words diminish when children receive self‐correction instruction. Imagery and copy instruction also reduce these errors, but less consistently. Five months later, self‐correction group maintained their advantage in spelling compared with students who read or performed dictation. Experiment 2 replicated the spelling instruction effects and showed large effects on children who had hardly received any spelling instruction in Spanish. Results indicate that research‐based practices can significantly improve spelling outcomes in primary children.  相似文献

ABSTRACT

Variations in the accuracy and stability of a word’s spelling can be used to gauge the quality of its underlying orthographic representation. The Lexical Quality Hypothesis (LQH) contends that words with higher quality cognitive representations should be accessed more efficiently than those with lower quality representations. If this is the case, deviations in spelling accuracy and stability should be reflected in differences in reading times. Here, 90 teenage participants read 30 words; reading times were recorded. After a 2-week delay, the students spelled these same words 3 times each to gain a measure of orthographic quality. In line with the LQH, faster reading speeds were observed for words with higher spelling accuracy and stability, even for words that were not always spelled perfectly. To our knowledge, our findings provide the first empirical support for the notion that orthographic quality exists along a continuum, both within and across individuals.  相似文献

Cross-linguistic studies suggest that the orthographic system determines the reading performance of dyslexic children. In opaque orthographies, the fundamental feature of developmental dyslexia is difficulty in reading accuracy, whereas slower reading speed is more common in transparent orthographies. The aim of the current study was to examine the extent to which different variables of words affect reaction times and articulation times in developmental dyslexics. A group of 19 developmental dyslexics of different ages and an age-matched group of 19 children without reading disabilities completed a word naming task. The children were asked to read 100 nouns that differed in length, frequency, age of acquisition, imageability, and orthographic neighborhood. The stimuli were presented on a laptop computer, and the responses were recorded using DMDX software. We conducted analyses of mixed-effects models to determine which variables influenced reading times in dyslexic children. We found that word naming skills in dyslexic children are affected predominantly by length, while in non-dyslexics children the principal variable is the age of acquisition, a lexical variable. These findings suggest that Spanish-speaking developmental dyslexics use a sublexical procedure for reading words, which is reflected in slower speed when reading long words. In contrast, normal children use a lexical strategy, which is frequently observed in readers of opaque languages.  相似文献

The present study investigated whether orthographic depth can increase the bias towards multi-letter processing in two reading-related skills: visual attention span (VAS) and rapid automatized naming (RAN). VAS (i.e., the number of visual elements that can be processed at once in a multi-element array) was tested with a visual 1-back task and RAN was measured in a serial letter naming task that introduced a novel manipulation (some letter sequences formed frequent words). Spanish-Basque and French-Basque bilingual children were tested at early (30 children in 1st and 2nd grade), and more advanced (24 children in 3rd, 4th and 5th grade) stages of reading acquisition to investigate whether they would be differently biased towards multi-letter processing due to reading in two shallow (Spanish, Basque), or a deep and a shallow (French, Basque) orthography. The French-Basque bilinguals, who read in a deep orthography, were expected to rely on larger orthographic units in reading and thus to be more biased towards multi-letter processing in both tasks. This was expected to be reflected by: (a) a uniform distribution of attention across letter strings in the VAS task, and (b) a greater interference of the embedded words on letter-by-letter naming in RAN, leading to longer naming times. The expected group differences were observed in the more advanced readers, with French-Basque bilinguals showing a wider distribution of VAS across letter strings and longer naming times in RAN.  相似文献

The majority of naturalistic reading occurs within passages. Therefore, it is important to understand how reading in context affects the division of labor between semantic and orthographic processing. However, it is difficult to compare the cognitive processes elicited by reading in context and lists because of the perceptual differences that define them. In 2 experiments, undergraduate students read 72 different words divided across three conditions (context, semantic-list, and orthographic-list). Participants then completed a memory task that was used to estimate either the semantic processing (surprise recall; Experiment 1) or orthographic processing (word stem completion; Experiment 2) elicited during reading. In both experiments, memory performance for words read in context more closely resembled words read in the semantic-list condition and differed greatly from those read in the orthographic-list condition. We interpret these results as showing that contextual reading biases the division of labor toward semantic processing and away from orthographic processing.  相似文献

We examined whether young children acquire orthographic knowledge during structured adult-led storybook reading even though minimal viewing time is devoted to print. Sixty-two kindergarten children were read 12 storybook “chapters” while their eye movements were tracked. Results indicated that the children quickly acquired initial mental graphemic representations of target nonwords. This learning occurred even though they focused on the target nonwords approximately one fourth of the total time while viewing the pages. Their ability to acquire the initial orthographic representations of the target nonwords and their viewing time was affected by the linguistic statistical regularities of the words. The results provide evidence of orthographic learning during structured storybook reading and for the use of implicit linguistic statistical regularities for learning new orthographic word forms in the early stages of reading development.  相似文献

In the current research the performance of children with and without reading disabilities was compared on a single word naming task. An analysis was carried out of the frequency and form of naming errors produced by the groups when naming real words and nonwords in a transparent orthography such as Spanish. A sample of 132 (45 normal readers, 87 reading disabled) Spanish children aged 9–10 years were selected, and an experiment was carried out to investigate if students with reading disabilities would have particular difficulties in naming words under conditions that require extensive phonological computation. While the children were performing the naming task, we recorded what they read to subsequently analyse the form, as well as the frequency, of naming errors as a function of lexicality, word frequency, word length and positional frequency of syllables. Disabled readers made more errors in nonwords, low frequency words and long nonwords. The findings support the hypothesis that poor phonological skills are a characteristic of reading disabled children.  相似文献

Remediation of a serious lack in reading fluency often takes the form of repeated reading exercises. The present study examines whether transfer of training effects to untrained (neighbour) words can be enhanced by training with an orthographic focus as compared with emphasising semantics. The effect of oral versus silent reading during training is studied as well. Two groups of reading‐disabled children (mean age=7 years, 11 months) were given repeated reading training with limited exposure duration (350 ms) in which 15 target words were repeated 20 times in exercises focused on either orthography (N=26) or semantics (N=25). The children were required to either read the target words aloud or perform the exercises silently, but this requirement appeared to have no effect on the training results. The results show that untrained neighbour words benefited more from training targets with an orthographic focus than from exercises with a semantic emphasis.  相似文献

Despite compelling evidence that analogy skills are available to beginning readers, few studies have actually explored the possibility of identifying individual differences in young children's analogy skills in early reading. The present study examined individual differences in children's use of orthographic and phonological relations between words as they learn to read. Specifically, the study addressed whether general analogical reasoning, short‐term memory and domain‐specific reading skills explain 5‐ to 6‐year‐olds' reading analogies (n=51). The findings revealed an orthographic analogy effect accompanied by high levels of phonological priming. Single‐word reading and use of visual analogies predicted young children's orthographic and phonological analogies in the regression analyses. However, different findings emerged from exploring profiles based on individual differences in reasoning skill. Indeed, when individual differences in composite scores of orthographic and phonological analogy were examined, group membership was predicted by word reading and early phonological knowledge, rather than general analogical reasoning skills. The findings highlight the usefulness of exploring individual differences in children's analogy development in the early stages of learning to read.  相似文献

Two experiments were conducted to compare the development of orthographic representations in children learning to read English and Greek. Nonsense words that either shared both orthography and phonology at the level of the rhyme with real words (comic-bomic), phonology only (comic-bommick), or neither (dilotaff) were created for each orthography. Experiment 1 compared children’s reading of bisyllabic and trisyllabic nonsense words likebomic vs.bommick, taffodil vs.tafoddyl, and found a significant facilitatory effect of orthographic rhyme familiarity for English only. Experiment 2 compared children’s reading of trisyllabic nonsense words that either shared rhyme phonology with real words (tafoddyl) or did not (dilotaff). Significant facilitation in reading accuracy was found for shared rhyme phonology in English, with a significant speed advantage in Greek. These results are interpreted in terms of the level of phonology that is represented in the orthographic recognition units being developed by children who are learning to read more and less transparent orthographies.  相似文献

The present study used a mediated priming paradigm to examine whether developmental differences exist in the integration of semantic information with orthographic and phonological information during visual word recognition. In Experiment 1, we found that the integration of semantics with phonology and orthography differed among third‐grade, sixth‐grade and college students: orthographically based mediated inhibition effects were found in third‐grade children, whereas phonologically based mediated inhibition effects were found in sixth‐grade children and college students. A second experiment was performed with adults to test the hypothesis that the orthographically based mediated inhibition effect observed with young children was due to deficits in orthographic processing. When stimulus quality was manipulated within the mediated priming paradigm, orthographically based mediated inhibition effects were found when targets were dim, whereas phonologically based mediated inhibition effects were found when targets were bright. Taken together, these results suggest that the allocation of activation during reading may depend on the processing demands of the word recognition system.  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

The visual attention (VA) span deficit hypothesis was found successfully to account for variability in developmental dyslexia (Bosse, Tainturier & Valdois, 2007). We conducted a cross‐sectional study on 417 typically developing children from first, third and fifth grades examining the role of VA span on the development of reading skills. A battery including reading, phoneme awareness and VA span tasks was administered. Results show that VA span predicts variations in learning to read independent of the influence of phoneme awareness. Moreover, whereas the specific influence of VA span on pseudoword reading declines from first to third grade, VA span has a significant and sustained influence across grades for the irregular words. In addition to phoneme awareness, the VA span contributes to reading performance from the beginning of literacy instruction, suggesting that it might have a long‐term influence on specific orthographic knowledge acquisition.  相似文献
