Awareness of the internal phonological structure of words is a causal factor in success with the alphabetic principle in word recognition. However, findings with the Lindamood Auditory Conceptualization (LAC) Test reveal 25–30% of the population show deficiency in a subtle component of phonological awareness termed comparator function. We argue that this comparator function—an ability to hold the phoneme and/or syllable segments of two phonological structures in mind and compare and represent any variations in the number, identity, or order of their segments—is a primary sensory-cognitive function underlying the secondary function of self-correction in word recognition and spelling. And since word recognition correlates highly with comprehension, comparator function also indirectly impacts this basic purpose for reading. We suggest that the needs of many individuals, including educators themselves, for development and refinement of phonological awareness/comparator function may be misdiagnosed and underaddressed unless more sensitive measures of phonological awareness are used. The consequence of inadequate assessment/remediation of these deficiencies in educators is that they may be less able to assess and address these deficiencies in their students. Standard phonics instruction is known to be ineffective in developing phonological awareness for many individuals. However, phonological deficits can be addressed both preventively and remedially using procedures that are fundamentally different from typical phonics instruction.  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

We examined whether akshara knowledge, phonological awareness, phonological memory, and RAN predict variability in word and nonword reading skills in Grade 1–4 children (N?=?200) learning to read Sinhala. Hierarchical regression analyses showed that akshara knowledge had the strongest unique association with both word and nonword reading accuracy across grades. Akshara knowledge and RAN predicted word and nonword reading fluency. The impact of phonological memory and syllable awareness on reading was mostly mediated by akshara knowledge, and phoneme awareness was not uniquely associated with word reading skills in any grade. These results suggest that there are multiple cognitive correlates of accurate and fluent word reading in Sinhala, and akshara knowledge is the most important predictor of learning to read words. The findings have implications for the literacy acquisition, development, and instruction in alphasyllabaries.

This study compared the early reading development of five‐year‐old children who were learning to read either English (an opaque orthography) or Welsh (a shallow orthography). The children were being educated in Welsh and English‐speaking primary schools in Wales during their first year of formal reading instruction. Teaching methods in both schools emphasised phonics. The reading, letter recognition and phonological awareness skills of the children were tested at three points in the year (November 1998, March 1999 and June 1999). By March, the children who were learning to read in Welsh were performing better than the English‐speaking group at word recognition. The English‐speaking children showed some improvement in their ability to read regular words across the three test phases, but no significant improvement in their ability to read irregular words. The children learning to read in Welsh also performed better on a phoneme counting task in March and June than the English‐speaking children. Both groups performed similarly on tests of letter recognition throughout the year. The results suggest that a transparent orthography facilitates reading acquisition and phoneme awareness skills from the earliest stages of reading development onward.  相似文献

The phonological awareness (PA), vocabulary, and word reading abilities of 19 children with cochlear implants (CI) were assessed. Nine children had an implant early (between 2 and 3.6 years) and 10 had an implant later (between 5 and 7 years). Participants were tested twice over a 12-month period on syllable, rhyme, and phoneme awareness (see James et al., 2005). Performance of CI users was compared against younger hearing children matched for reading level. Two standardized assessments of vocabulary and single word reading were administered. As a group, the children fitted early had better performance outcomes on PA, vocabulary, and reading compared to hearing benchmark groups. The early group had significant growth on rhyme awareness, whereas the late group showed no significant gains in PA over time. There was wide individual variation in performance and growth in the CI users. Two participants with the best overall development were both fitted with an implant late in childhood.  相似文献

Phonological awareness is a strong predictor of children's progress in literacy acquisition. There are different ways of segmenting words into sound sequences – syllables, phonemes, onset-rime – and little is known about whether these different levels of segmentation vary in their contribution to reading and writing. Does one of them – for example, phoneme awareness – play the major role in learning to read and spell making the other phonological units irrelevant to the prediction of reading? Or do different levels of analysis make independent contributions to reading and spelling?

Our study investigated whether syllable and phoneme awareness make independent contributions to reading and spelling in Greek. Four measures were used: syllable awareness, phoneme awareness, reading and spelling. Analyses of variance showed that Greek speaking children found it easier to analyse words into syllables than phonemes, irrespective of the influence of task variables such as position of the phonological element, word length, and placement of stress in the word. Regression analyses showed that syllable and phoneme awareness make significant and independent contributions to learning written Greek. We conclude that phonological awareness is a multidimensional phenomenon and that the different dimensions contribute to reading and writing in Greek.

A large battery of reading related skills were orally administered to 111 4-year old and 118 5-year old Korean kindergartners, who were also tested on reading of regular and irregular Korean Hangul words. In regression equations, speeded naming was uniquely associated with reading of both regular and irregular words. In contrast, only the three measures of phonological awareness at the levels of phoneme onset, coda, and syllable uniquely explained Hangul regular word recognition, whereas only morphological awareness consistently explained irregular word recognition. Results suggest somewhat different cognitive demands for reading of regular and irregular words, based on the dual-route model, in Korean Hangul.  相似文献

This paper reports 3 studies comparing thereading and phonological skills of childrenwith Down syndrome (DS) and younger normallydeveloping children of similar reading level.In Study 1, the two groups did not differ insight word or nonword reading, but the childrenwith DS did marginally less well on syllablesegmentation, rhyme and phoneme detectiontasks. Group differences in syllable andphoneme awareness appeared attributable todifferences in verbal ability (BPVS, vocabularyknowledge); however, a significant impairmentin rhyme detection remained in an analysis ofsub-groups equated in vocabulary knowledge. Thedeficit in rhyme observed in DS was replicatedin Studies 2 and 3 using simplified tests ofrhyme judgement, with the majority of childrenwith DS performing at chance on the rhymemeasures. In contrast, the two groups did notdiffer in their ability to detect phonemes inany of the 3 studies and performed above chancein initial phoneme detection and alliterationjudgement tasks, although the identification offinal phonemes was at a much lower level. Correlational analyses indicated a relationshipbetween phonological skills and reading inboth groups. However, for children with DS,letter-sound knowledge did not predict readingwhereas it did for normal controls. It issuggested that children with DS do not possessfull phoneme awareness; although they canidentify initial phonemes in words, they do notunderstand phoneme invariance and may rely lesson phonological skills for reading thancontrols.  相似文献

There is a consensus that dyslexia is on a continuum with normal reading skill and that dyslexics fall at the low end of the normal range in phonological skills. However, there is still substantial variability in phonological skill among dyslexic children. Recent studies have focused on the high end of the continuum of phonological skills in dyslexics, identifying a “surface” dyslexic, or “delayed” profile in which phonological skills are not out of line with other aspects of word recognition. The present study extended this work to a longitudinal context, and explored differences among subgroups of dyslexics on a battery of component reading skills. Third grade dyslexics (n=72) were classified into two subgroups, phonological dyslexics and delayed dyslexics, based on comparisons to younger normal readers at the same reading level (RL group). The children were tested at two points (in third and fourth grade). The results revealed that the classification of dyslexics produced reliable, stable, and valid groups. About 82 percent of the children remained in the same subgroup category when retested a year later. Phonological dyslexics were lower in phoneme awareness and expressive language. Delayed dyslexics tended to be slower at processing printed letters and words but not at rapid automatic naming of letters, and relied more heavily on phonological recoding in reading for meaning than did phonological dyslexics. A subset of the delayed dyslexics with the traditional “surface dyslexic” pattern (relatively high pseudoword and low exception word reading) was also identified. The surface subgroup resembled the RL group on most measures and was not very stable over one year. The results are discussed in light of current models of dyslexia and recent subgrouping schemes, including the Double-Deficit Hypothesis.  相似文献

Phonemic and prosodic awareness are both phonological processes that operate at different levels: the former at the level of the individual sound segment and the latter at the suprasegmental level across syllables. Both have been shown to be related to word reading in young readers. In this study we examine how these processes are differentially related to reading monosyllabic and multisyllabic words. Participants were 110 children in grades four and five who were asked to read monosyllabic and three- and four-syllable words matched for frequency. Phonemic awareness was assessed via a phoneme elision task; prosodic awareness was assessed by a task asking participants to identify the syllable bearing primary stress in a spoken word. Results showed that phonemic and prosodic awareness were independent predictors of short word reading, and both phonological factors made independent contributions to multisyllabic word reading, showing that phonemic and prosodic awareness are complementary but not redundant processes. Only prosodic awareness survived control for simple decoding ability in the reading of long words, suggesting that suprasegmental phonology gives added value to our understanding of reading multisyllabic words.  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

The present study examined cross-linguistic relationships between phonological awareness in L1 (Hebrew) and L2 (English) among normal (N = 30) and reading disabled (N = 30) Hebrew native speaking college students. Further, it tested the effect of two factors: the lexical status of the stimulus word (real word vs. pseudoword) and the linguistic affiliation of the target phoneme (whether it is within L1 or L2) on phonological awareness. Three parallel experimental phonological awareness tasks were developed in both languages: phoneme isolation, full segmentation, and phoneme deletion. As expected, the results revealed lower levels of phonological awareness in the L2 than in the L1, and in the reading disabled than in the normal reader group. The lexical status of the target word was a reliable factor predicting individual differences in phonological awareness in L2. It was also found that the linguistic affiliation of the target phoneme was a reliable factor in predicting L2 phonological awareness performance in both reader groups. The results are discussed within the framework of phonological representation and language-specific linguistic constraints on phonological awareness.  相似文献

The current study examined the contribution of cross-language phonological and morphological awareness to reading acquisition in bilingual children. Participants were 140 children (M age = 8.26 years) between Grades 1–4 who learned Chinese as their first language and English as their second language. Awareness of phoneme, onset-rime, compound structures and polysemy (i.e. words with multiple meanings) were measured using conceptually comparable tasks in both languages. Oral vocabulary, single word reading, and reading comprehension were also assessed. Path analysis revealed significant direct effects from Chinese rime awareness to both English word reading and reading comprehension. English phoneme awareness also had a significant direct effect on Chinese word reading. There was a significant direct effect from Chinese polyseme identification to English reading comprehension. Awareness of compound structure in one language also had indirect effects on reading outcomes in the other language via within-language compound structure awareness. These finding provided evidence for bi-directional cross-language phonological and morphological transfer in Chinese–English bilingual reading acquisition.  相似文献

This study investigated the phonological skills of university students who were unexpectedly poor spellers relative to their word reading accuracy. Compared with good spellers, unexpectedly poor spellers showed no deficits in phonological memory, selection of appropriate graphemes for phonemes in word misspellings and nonword spellings, and phoneme awareness. In contrast, poor readers–poor spellers performed worse than the other groups at all but the last of these tasks. Although unexpectedly poor spellers misread nonwords more often than good spellers and took longer to begin pronouncing long, difficult-to-spell words, they took no longer to begin pronouncing shorter words and the names of corresponding pictures. The difficulty with reading nonwords and long words was thus interpreted as arising at the stage of identifying and parsing the orthographic input rather than phonological retrieval. The findings indicate that unexpectedly poor spellers of the type studied here do not have a mild phonological deficit.  相似文献

This study examined the relative contribution of letter-name knowledge and phonological awareness to literacy skills and the relationship between letter-name knowledge and phonological awareness, using data from Korean-speaking preschoolers. The results revealed that although both letter-name knowledge and phonological awareness made unique contributions to literacy skills (i.e., word reading, pseudoword reading, and spelling), letter-name knowledge played a more important role than phonological awareness in literacy acquisition in Korean. Letter-name knowledge explained appreciably greater amount of variance and had larger effect sizes in literacy skills. Furthermore, children with greater syllable, body (e.g., segmenting cat into ca-t), and phoneme awareness had higher levels of letter-name knowledge. In particular, children’s syllable awareness and body awareness were positively associated with their letter-name knowledge, even after controlling for children’s phoneme awareness. These results suggest that Korean children’s awareness of larger phonological units (i.e., syllable and body) in addition to phoneme awareness may mediate the relationship between letter-name knowledge and literacy acquisition in Korean, in contrast with previous findings in English that have demonstrated a positive relationship only between phoneme awareness and letter-name knowledge, and the hypothesis that phoneme awareness mediates the relationship between letter-name knowledge and literacy acquisition.  相似文献

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

This study investigated the relationships between phonological awareness and reading in Oriya and English. Oriya is the official language of Orissa, an eastern state of India. The writing system is an alphasyllabary. Ninety‐nine fifth grade children (mean age 9 years 7 months) were assessed on measures of phonological awareness, word reading and pseudo‐word reading in both languages. Forty‐eight of the children attended Oriya‐medium schools where they received literacy instruction in Oriya from grade 1 and learned English from grade 2. Fifty‐one children attended English‐medium schools where they received literacy instruction in English from grade 1 and in Oriya from grade 2. The results showed that phonological awareness in Oriya contributed significantly to reading Oriya and English words and pseudo‐words for the children in the Oriya‐medium schools. However, it only contributed to Oriya pseudo‐word reading and English word reading for children in the English‐medium schools. Phonological awareness in English contributed to English word and pseudo‐word reading for both groups. Further analyses investigated the contribution of awareness of large phonological units (syllable, onsets and rimes) and small phonological units (phonemes) to reading in each language. The data suggest that cross‐language transfer and facilitation of phonological awareness to word reading is not symmetrical across languages and may depend both on the characteristics of the different orthographies of the languages being learned and whether the first literacy language is also the first spoken language.  相似文献

The utility of teaching reading using rime-based readingstrategies with prereaders was examined. Two experiments are presentedthat studied the effects of a rime-based reading program with FirstNations prereaders; one experiment with Shuswap kindergartners andthe other with Heiltsuk Grade 1 children. Rhyming, phoneme identity,letter-sound knowledge, phonological working memory, First Nationslanguage speaking ability, and reading were measured. In the Shuswapgroup, the reading program increased the abilities that werespecifically taught, rhyming, initial phoneme identity, letter-sounds,and word reading by rime-analogy, compared to the control group.Children also developed abilities that were not specifically taught,final phoneme identity and reading by letter recoding, and could use therime-analogy strategy to read words with unfamiliar rime endings.Phonological working memory remained unchanged. The Heiltsuk childrengained in reading compared to a Grade 1 comparison group. Pretestletter-sound knowledge and rhyming were related to later reading butphoneme identity and First Nations language ability were not. Progressin phonological awareness and word reading can be enhanced in prereadersby adding experience with rime-based strategies to the readingprogram.  相似文献

Phonological coding, measured by the oral reading of nonwords, and orthographic coding, measured by the discrimination of words from homophonic nonwords (e.g., rane, rain), were compared for pairs of older children with reading disabilities (RD) and younger nondisabled readers matched on word recognition. Phonological coding was substantially lower for most children with RD, indicating a unique developmental deficit in phonological coding rather than an equal developmental lag across all component reading skills. Data from identical and fraternal twins indicated that the phonological coding deficit of the children with RD was highly heritable and accounted for most of the heritable variance in their word recognition deficits. The deficits of the twins with RD in segmental language skills (rhyming and phoneme segmentation) were related to the heritable variance in their phonological coding deficits. Orthographic coding was not significantly heritable, and it accounted for much of the environmental variance in word recognition deficits. Implications of the results for the remediation of reading disability are discussed.  相似文献

We studied the relationship between rapid serial naming (RSN) and orthographic processing in Russian, an asymmetrically transparent orthography. Ninety-six students (M age = 13.73) completed tests of word and pseudoword reading fluency, spelling, orthographic choice, phonological choice, phoneme awareness (PA), and RSN. PA was a better predictor of orthographic skills and pseudoword reading accuracy than RSN, which accounted for more variance in word and pseudoword reading fluency. Controlling for pseudoword reading fluency washed out RSN’s contribution to word reading fluency. These results extend previous findings questioning the role of RSN as an index of orthographic processing skills and support the idea that RSN taps into automaticity/efficiency of processing print-sound mappings.  相似文献
