Word reading fluency is a key component in the process of reading. In order to understand its acquisition it is crucial to conduct longitudinal studies. The aim of this work was to describe the development of word recognition in Spanish, considering accuracy and speed, from a longitudinal perspective. A group of 31 children were followed for six years. Reading performance was assessed with a list of 72 stimuli in which lexicality, frequency and length were manipulated. Results show that initial gains in reading accuracy occurred very rapidly. However, the growth of reading speed was found to be more difficult and complex, and automatic word recognition remains low at the end of Grade 6. Low frequency, long words were the most difficult stimuli. High stability in reading speed was observed and it was a relevant indicator that differentiates between good and poor readers. The findings also highlighted the need to develop training programs with the specific aim of improving word reading fluency throughout primary education.  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

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

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

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

Italian developmental dyslexic readers show a striking length effect and have been hypothesised to rely mostly on nonlexical reading. Our experiments tested this hypothesis by assessing whether or not the deficit underlying dyslexia is specific to lexical reading. The effects of lexicality, word frequency and length were investigated in the same group of children in four separate experiments. Although dyslexics were slower and less accurate than skilled readers and had large length effects, they showed lexicality and word frequency effects in both reading aloud and lexical decision. In a cross‐experiment comparison, we show that a single global factor explains a large proportion of the difference in reading performance between dyslexic and skilled readers. This factor may indicate a deficit at a prelexical level of analysis. Lexical activation seemed spared in the dyslexic children based on the effects of lexicality and frequency. These findings contrast the hypothesis that Italian dyslexics primarily engage in nonlexical reading.  相似文献

The measure words correct per minute (WC/M) incorporates a measure of accurate aloud word reading and a measure of reading speed. The current article describes two studies designed to parse the variance in global reading scores accounted for by reading speed. In Study I, reading speed accounted for more than 40% of the reading composite score variance in 4th‐, 5th‐, and 10th‐grade students. In Study II, reading speed accounted for more than 30% of the reading/language arts composite score variance of fourth‐ and fifth‐grade students. Across both studies, when reading speed was combined with words read correctly and converted to WC/M the additional variance accounted for was less than 10% with one exception, fourth‐grade students' reading/language arts scores. These findings are consistent with various theories regarding reading speed, provide direction for future researchers, and may assuage those concerned that WC/M is primarily a measure of aloud, accurate word reading (i.e., word calling). © 2010 Wiley Periodicals, Inc.  相似文献

The development of word reading and word spelling was examined in French speaking children initially instructed either by a phonic or a whole-word method. Second, fourth and sixth graders were administered to reading and spelling tests in which grapho-phonological regularity, frequency, length and lexicality were manipulated. The results showed that in both curricula, reading and spelling acquisition can be characterized by a parallel increase in the use of sub-lexical correspondences and in the reliance on word-specific information. Contrary to a simple view of lexical development according to which the use of analytical knowledge and the use of word-specific knowledge correspond to two different cognitive processes that develop independently from each other, whole-word children did not appear to rely more on whole-word knowledge. On the contrary, and paradoxically, grade 2 whole-word children tended to use analytical correspondences to a greater extent than their peers. In later development, reading matched phonic and whole-word groups did not differ from each other. It is argued that the results support the hypothesis that the acquisition of sub-lexical correspondences constitutes a necessary step in the acquisition of reading and spelling. We conclude that the analytic comparison of different curricula provides a naturalistic tool for the study of the dynamics of development.  相似文献

This is an individual case study combined with subject sampling which compared the reading performance of good and poor Brazilian 4th grade children with Scottish children of equivalent reading competence and age range. A measure of efficient performance -- low error rates and fast vocal reaction-times for correct responses to words (of varying familiarity, regularity and length) and non-words (of varying length) -- was obtained and used as a basis for the identification of inefficiencies among the subjects whose results were outside the main range. Competent reading in Brazilian Portuguese and Scottish showed similarities in regard to time processing and error rates for the reading of words and non-words and mainly differed in terms of the generality of the regularity effect and of the rate of letter processing of words and for non-words. In what concerns impaired reading, in both nationalities there were examples of pure phonological dyslexia and of impairments affecting both lexical and non-lexical processes with a bias to the phonological pattern. In contrast to the Scottish sample, no cases of predominant morphemic dyslexia nor ambiguous cases were found among the Brazilians.  相似文献

Albanian is an Indo-European language with a shallow orthography, in which there is an absolute correspondence between graphemes and phonemes. We aimed to know reading strategies used by Albanian disabled children during word and pseudoword reading. A pool of 114 Kosovar reading disabled children matched with 150 normal readers aged 6 to 11?years old were tested. They had to read 120 stimuli varied in lexicality, frequency, and length. The results in terms of reading accuracy as well as in reading times show that both groups were affected by lexicality and length effects. In both groups, length and lexicality effects were significantly modulated by school year being greater in early grades and later diminish in length and just the opposite in lexicality. However, the reading difficulties group was less accurate and slower than the control group across all school grades. Analyses of the error patterns showed that phonological errors, when the letter replacement leading to new nonwords, are the most common error type in both groups, although as grade rises, visual errors and lexicalizations increased more in the control group than the reading difficulties group. These findings suggest that Albanian normal children use both routes (lexical and sublexical) from the beginning of reading despite of the complete regularity of Albanian, while children with reading difficulties start using sublexical reading and the lexical reading takes more time to acquire, but finally both routes are functional.  相似文献

In this study subjects were presented with a series of letter strings and required to either make a lexical decision about each one or to judge the number of syllables present. The factors manipulated were lexicality (word/nonword), word frequency (high/low), syllables (one/two), and array length (4, 5, 6 letters). The results showed that neither task was affected by number of syllables. Lexical decision times were influenced by word frequency and lexicality but not affected by array length or number of syllables. Syllable judgments were found to be significantly quicker for four- and six-letter words compared with five-letter words. Implications of these results in relation to the processing demands of lexical decision and syllable judgment tasks are discussed.  相似文献

This study investigated the phonological contribution during visual word recognition in child readers as a function of general reading expertise (third and fifth grades) and specific word exposure (frequent and less‐frequent words). An intermodal priming in lexical decision task was performed. Auditory primes (identical and unrelated) were used in order to directly activate phonological codes independently of orthographic processing. Overall, the results revealed a widespread phonological priming effect in both grades. There was a significant interaction between grade, priming condition and frequency, revealing that the impact of frequency on identity priming differed between grades. In third grade, the results indicated that the priming effect was greater for less‐frequent than for frequent words. In fifth grade, priming effects were similar for both frequent and less‐frequent words. These findings indicate that print and speech processing systems are interconnected in young readers. Moreover, phonological codes play an important role in word recognition throughout reading development.  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

Tests of a model of the expected relationships between language abilities and reading achievement measures from the beginning of kindergarten through third grade are discussed. At kindergarten, more global language abilities influenced early, wholistic measures of reading achievement, including letter and number naming. At Grade 1, these earlier accomplishments had a direct effect on word recognition, but a second direct effect was also apparent for word and pheneme segmentation measured in kindergarten. Comprehension at Grade 1 was influenced primarily by word recognition abilities at the same time. At Grade 2, comprehension influenced word recognition; at Grade 3, word recognition and comprehension were essentially independent. These findings are considered in the context of Frith's three-phase hypothesis of reading acquisition. A rationale for testing the potential of training in auditory segmentation to modulate the effects of developmental dyslexia is presented.  相似文献

Effects of word and morpheme familiarity on reading of derived words   总被引：1，自引：0，他引：1  
The purpose of this study is to examine factors that influence students’ reading of derived words. Recent research suggests that the lexical quality of a derived word depends on the familiarity of the word, its morphemic constituents (i.e., base word and affixes), and the frequency with which the base word appears in other words (i.e., members of the same word family or family frequency). On the premise that better and more experienced readers have higher quality lexical representations, we explore the extent to which accuracy of reading derived words by 4th and 6th graders is related to measures of familiarity, including derived and base word frequencies, family size, average family frequency, and word length. The results of an exploratory factor analysis indicated that these measures formed two factors, one representing morphemic constitution and the second representing exposure to the word family; both factors accounted for significant variance in the students’ derived word reading. Comparisons of sets of derived words contrasted on familiarity properties showed that performance on derived words, overall, is better for 6th than 4th graders and for good than poor readers. On the measures of family frequency and family size, there were significant discrepancies between grade level and reading ability and frequency characteristics. These add support to the view that morphemic analysis and wide reading experience contribute to derived word reading.  相似文献

The present study investigated the associations of visual-spatial attention with word reading fluency and spelling in 92 third grade Hong Kong Chinese children. Word reading fluency was measured with a timed reading task whereas spelling was measured with a dictation task. Results showed that visual-spatial attention was a unique predictor of speeded reading accuracy (i.e., the total number of words read correctly divided by the total number of words read in a timed reading task) but not reading speed (i.e., the number of words read correctly in the same task) after controlling for age, non-verbal intelligence, morphological awareness, phonological awareness, orthographic knowledge, and rapid automatized naming. Visual-spatial attention also explained unique variance in word spelling measured with a dictation task after the same control variables. The findings of the present study suggest that visual-spatial attention is important for literacy development in Chinese children.  相似文献

Thai, a tonal language, has its own distinctive alphabetic orthography. The study investigates reading and spelling development in Thai children, with an aim of examining the grain size that is predominantly used when reading and spelling. Furthermore, word and nonword lists were developed to examine the acquisition of the complex system of vowels and tone rules in Thai. Reading and spelling of words and nonwords were assessed in 60 Thai children ranging in age from 7 to 9 years 8 months from Grade(s) 1, 2, and 3. A lexicality effect was found for both reading and spelling. Spelling lagged behind reading in the Grade 1 children. Development rapidly increased between the youngest Grade 1 children and the older Grade 2 and 3 children. For word reading there were significantly more lexical errors than phonological errors. Beginning readers appear to predominantly use a larger lexico-syllabic grain size to read Thai.  相似文献

The study reports 2 lexical decision experiments on below average readers' sensitivity to Basic Orthographic Syllabic Structure (BOSS) of Taft in visual word recognition. In Experiment 1, 20 words and 20 pseudo words with BOSS and non-BOSS conditions (e.g., tractOR, tracTOR; BLUNDin, BLUNdin) were presented on a microcomputer screen to 75 grades 4, 5, and 6 poor readers divided into poor reading/spelling subgroups. ANOVA of the correct reaction time scores shows significant main effects for grade, reading/spelling subgroup and lexicality with both word and pseudo word BOSS condition being the most discriminating. Experiment 2 provides a stronger test for the BOSS parsing principle with 48 items of correctly affixed real words (e.g., reTURN), pseudo-affixed words (e.g., ENTer), and incorrectly affixed pseudo words (e.g., AVOIDer) presented on the microcomputer screen for lexical decision. The target subjects were 20 grade 6 and 22 grade 7 below average readers compared with 23 above average chronological age control readers in each of the same grades 6 and 7. ANOVA results of the correct RT scores show significant main effects for reding level and affixation condition with the correctly affixed BOSS condition being the most discriminating. Taken together, the 2 experiments suggest that children are sensitive to the BOSS parsing principle and this could be used in promoting word knowledge.  相似文献

We develop and test a dual-route model of genetic effects on reading aloud and spelling, based on irregular and non-word reading and spelling performance assessed in 1382 monozygotic and dizygotic twins. As in earlier research, most of the variance in reading was due to genetic effects. However, there were three more specific conclusions: the first was that most of the genetic effect is common to both regular and irregular reading. In addition to this common variance evidence was found for distinct genes influencing the acquisition of a lexicon of stored words, and additional genetic effects influencing the acquisition of grapheme–phoneme correspondence rules. The third conclusion, from a combined model of reading and spelling, is that reading and spelling have a common genetic basis. Models that did not distinguish lexical and non-lexical performance fit significantly worse than dual route genetic models. An implication of the research is that models of reading, whether connectionist or dual-route, must allow for the genetic independence of neurological processes underlying the decoding of non-words and irregular words.  相似文献

Speed, accuracy, and types of errors in decoding lists of words and pseudo words and performance in two phonemic awareness tasks were assessed for German and American children in the first and second grades. German children were significantly better than American children only in pseudo word decoding measures across grades. Between group analyses showed that American children committed more vowel and word substitution errors in both decoding accuracy tasks than German children. Word substitution errors were more likely in word decoding than in pseudo word decoding for children in both languages. Within group analyses indicate that variance in decoding errors and speed accounted for by word substitution versus nonword and vowel versus consonant errors differed dependent on grade and whether real or pseudo words were read. Results suggest successful reading in English depends upon more complex grapheme to phoneme correspondence rules than does reading in German.  相似文献
