Computer speech-based remediation for reading disabilities: the size of spelling-to-sound unit in a transparent orthography

This study was designed to assess the effects of four reading-training procedures for children with reading disabilities (RD) in a transparent orthography, with the aim of examining the effects of different spelling-to-sound units in computer speech-based reading. We selected a sample of 83 Spanish children aged between 7 years 1 month and 10 years 6 months (M = 105.2, SD = 7.8) whose pseudoword reading performance was below the 25th percentile and IQ > 90. The participants were randomly assigned to five groups: (a) the whole-word training group (WW) (n = 17), (b) the syllable training group (S)(n = 16), (c) the onset-rime training group (OR) (n = 17), (d) the phoneme training group (P) (n = 15), and (e) the untrained control group (n = 18). Children were pre- and post-tested in word recognition, reading comprehension, phonological awareness, and orthographic and phonological tasks. The results indicate that experimental groups who participated in the phoneme and syllable conditions improved their word recognition in comparison with the control group. In addition, dyslexics who participated in the phoneme, syllable, and onset-rime conditions made a greater number of requests during computer-based word reading under conditions that required extensive phonological computation (low frequency words and long words). Reading time, however, was greater for long words in the phoneme group during computer-based reading. These results suggest the importance of training phonological processes in improving word decoding in children with dyslexia who learn in a consistent orthography.     

A Comparison of Phonological Awareness Skills in Early French Immersion and English Children

This 2-year study examined the effects of early second language exposure on phonological awareness skills. Syllable, onset-rime and phoneme awareness skills of 72 anglophone children attending English or French immersion programs in primary and grade 1 were investigated. Three-way mixed ANOVAS revealed the following effects and interactions. In terms of grade effect, grade 1 students performed significantly better than primary students on phoneme and onset-rime tasks. A stimulus language effect was observed for the three levels of phonological awareness. All children performed better on English tasks than on French ones. Interaction effects of stimulus language by program were revealed for phoneme as well as syllable tasks. Posthoc analyses revealed that French students performed better on English phoneme and syllable tasks than on French, while English students performed better than French immersion students on French syllable tasks. Correlational analyses revealed significant relationships between reading and phoneme and onset-rime phonological awareness tasks regardless of program of instruction (English, French immersion) or language of reading test (English, French). Syllable awareness was only significantly correlated with the French non-word reading task for the French immersion students.     

Phoneme awareness is a better predictor of early reading skill than onset-rime awareness

We present the results of a short-term longitudinal study. Children in the early stages of learning to read (5 and 6 year olds) were administered three different tasks (deletion, oddity, and detection) tapping awareness of four phonological units (initial phoneme, final phoneme, onset, and rime). Measures of phoneme awareness were the best concurrent and longitudinal predictors of reading skill with onset-rime skills making no additional predictive contribution once phonemic skills were accounted for. The findings are related to recent controversy over the role of large versus small phonological units as predictors of children's reading skills.     

语音意识的不同成分在汉语儿童英语阅读学习中的作用

研究一测查了74名小学三、五年级儿童辨别、删除汉语和英语音节、首音-韵脚、音位等不同语音成分的能力以及英语单词阅读,考察语音意识不同成分与英语阅读学习的关系及母语语音意识的作用途径.研究二测查了83名英语阅读较差和73名英语阅读一般及以上儿童的英语语音删除和单词认读能力,考察阅读水平对于语音意识作用的调节效应.结果表明:(1)英语首音-韵脚意识对英语阅读具有显著的独立贡献;(2)汉语首音-韵脚意识和声调意识分别对英语单词认读和假词拼读具有显著的独立贡献,二者通过英语首音-韵脚意识的中介发挥作用;(3)阅读水平具有显著的调节作用.首音-韵脚意识是正常儿童阅读的有效预测变量,而音节意识是低水平儿童阅读的有效预测变量.上述结果与有关语音意识各成分在英语为母语儿童阅读学习中作用的研究结果不同,提示第二语言的学习具有特殊性,母语经验影响着个体第二语言学习的过程.     

Phonological Awareness and Reading Proficiency in Adults with Profound Deafness

This study investigated differences in the phonological knowledge and reading skill of deaf adults using three experimental conditions that tested sensitivity to syllables, rhyme, and phonemes. Analysis of response latencies and accuracy in the three awareness tasks demonstrated that skilled deaf readers had superior phonological awareness skill to that of less-skilled readers and showed less reliance on orthography when making their phonological judgments. Rhyme had greater independent predictive strength than syllable or phoneme awareness for reading comprehension. Phoneme awareness did not contribute independently to either reading comprehension or word reading, but it did independently predict application of grapheme-phoneme correspondences.     

Paired-associate learning, phoneme awareness, and learning to read

We report two studies examining the relations among three paired-associate learning (PAL) tasks (visual-visual, verbal-verbal, and visual-verbal), phoneme deletion, and single-word and nonword reading ability. Correlations between the PAL tasks and reading were strongest for the visual-verbal task. Path analyses showed that both phoneme deletion and visual-verbal PAL were unique predictors of a composite measure of single-word reading and of irregular word reading. However, for nonword reading, phoneme deletion was the only unique predictor (and visual-verbal PAL was not a significant predictor). These results are consistent with the view that learning visual (orthography) to phonological mappings is an important skill for developing word recognition skills in reading and that individual differences in this ability can be tapped experimentally by a PAL task.     

It doesn't matter whether onset and rime predicts reading better than phoneme awareness does or vice versa

Hulme et al. argue against our hypothesis that there are two routes from onset and rime awareness to reading: an indirect route whereby onset-rime awareness feeds into the development of phoneme awareness which in turn affects children's reading, and a direct route by which onset-rime awareness makes an independent contribution to children's reading. The evidence that Hulme et al. present against this hypothesis is not convincing, partly because our hypothesis actually predicts most of their results and partly because of weaknesses in the design of Hulme et al.'s study and in the unusual procedures that they employed.     

The growth of reading skills in children with Down Syndrome

There appears to be a close and probably causal relationship between early variations in phoneme skills and later reading skills in typically developing children, though the pattern in children with Down Syndrome is less clear. We present the results of a 2-year longitudinal study of 49 children with Down Syndrome (DS) and 61 typically developing (TD) control children with similar initial levels of reading skill. Phoneme awareness and vocabulary were strong concurrent predictors of initial levels of reading skill in both groups. However, longitudinally phoneme awareness was a predictor of the growth of reading skills in TD children but not in children with DS. There was a very high degree of longitudinal stability in reading skills in children with DS, and initial levels of reading skills seemed to be highly constrained by general language skills, as indexed by vocabulary knowledge, in this population. We conclude that reading development in children with DS shows similarities and differences to the pattern observed in TD children and that phoneme awareness appears to be a less powerful influence on the development of reading skills in children with DS.     

Onsets and rimes in a phonologically transparent orthography: differences between good and poor beginning readers of Dutch.

This study investigates whether beginning readers of Dutch develop onset-rime units when these units are emphasized in their reading method, even when the orthography is transparent at the grapheme-phoneme level. The speed of naming intact pseudowords (wot) was compared with the speed of naming pseudowords with an onset-rime (w ot) or body-coda (wo t) segmentation. Whereas body-coda items consistently slowed down naming for both good and poor readers, the onset-rime effect covaried with reading skill: it changed from inhibitory for good readers to facilitatory for poor readers. Two alternative explanations are proposed.

Effects of orthographic transparency on reading and phoneme awareness in children learning to read in Wales

The relationship between the development of reading skills and the consistency of the orthography (writing system) is investigated in a study that examines reading acquisition in children living in Wales. Performance of children learning to read Welsh (a transparent alphabetic orthography) on tests of reading and phoneme detection was compared with the performance of children learning to read English (an opaque alphabetic orthography). The children were tested during their second year of formal reading instruction at school when they were aged between 5 and 6 years, and again one year later. The children learning to read in Welsh performed significantly better at reading both real words and nonwords than children learning to read in English. The English readers made fewer phonologically based reading errors. The Welsh readers also performed better on a phoneme awareness task. These findings support the claim that children learn to read more quickly in a transparent orthography, and provide further evidence that the consistency of the orthography influences the initial adoption of different strategies for word recognition.     

Getting ready for reading: A follow‐up study of inner city second language learners at the end of Key Stage 1

Background: A previous study (Stuart, 1999) showed that early phoneme awareness and phonics teaching improved reading and spelling ability in inner‐city schoolchildren in Key Stage 1, most of whom were learning English as a second language. Aims: The present study, a follow‐up of these children at the end of Key Stage 1, addresses four main questions: (1) Are these improvements maintained to the end of Key Stage 1? (2) Are different patterns of cognitive process evident in the word recognition skills of phonics trained versus untrained children? (3) Do the phonics trained children now also show a significant advantage in reading comprehension? (4) Are there differences in amount of reading, in self‐concept as readers and in oral vocabulary development between phonics trained and untrained children? Relationships between reading and spelling ages and Key Stage 1 SATs levels are also explored. Sample: Data are reported from 101 seven‐year‐olds (85 of whom were second language learners) remaining from the original 112 children reported on previously. Method: Children were tested on four standardized tests of reading, spelling and vocabulary, and on a further six experimental tests of phoneme segmentation, grapheme‐phoneme correspondence knowledge, regular, exception and nonword reading, author recognition and reading self‐concept. Results: Lasting influences of early phoneme awareness and phonics teaching on phoneme awareness, grapheme‐phoneme correspondence knowledge, word reading and spelling were found. Part of the previously untrained group had now received structured phonics teaching, and were therefore treated as a third (late trained) group. Early and late‐trained groups showed similar levels of attainment and similar cognitive processing patterns, which were different from the untrained group. However, there were no influences of training on reading comprehension, self‐concept or oral vocabulary. Conclusions: Early phoneme awareness and phonics training efficiently accelerates the word recognition and spelling skills of first and second language learners alike. However, this is not sufficient to bootstrap the development of language comprehension in the second language learners. Further research is needed into the kinds of language teaching that will best develop their oral and written language comprehension.     

The relationship between morphological awareness and reading comprehension in Spanish‐speaking children

In the last decades, a series of studies has explored the role of morphological awareness on reading comprehension. Path analysis studies performed in English have shown that morphological awareness benefits reading comprehension both directly and indirectly, through word decoding. This issue has seldom been explored in Spanish. The aim of this study was to replicate in Spanish the results previously found in English. We used path analysis to assess three alternative models of the relationship between morphological awareness, word decoding and reading comprehension in 4th grade Spanish‐speaking children. Contrary to English, we found that morphological awareness benefits reading comprehension only directly. We conclude that in Spanish, in which accurate and fluent pronunciation of written words can be achieved through grapheme‐to‐phoneme conversion rules, morphological awareness does not help the correct pronunciation of words. Thus, morphological awareness is not relevant for word decoding in Spanish but is related to reading comprehension since this type of morphological knowledge provides access to the semantic and syntactic information of new words.     

ACQUISITION OF BLENDING SKILLS: COMPARISONS AMONG BODY-CODA,ONSET-RIME,AND PHONEME BLENDING TASKS

Following research on phonological awareness development, this study explores children's acquisition of blending skills using three types of stimuli: body-coda, onset-rime, and phonemes. The results demonstrated that kindergarten children consistently gained proficiency for blending body-coda stimuli prior to onset-rime stimuli and phonemes. The results are interpreted to support an instructional process where blending is treated as a generalizable skill, and children work with the simplest material first. Thus, our proposition is that children be trained to blend body-codas first, then progress to more phonologically difficult blending tasks such as onset-rimes and phonemes.     

Age and schooling effects on early literacy and phoneme awareness

Previous research on age and schooling effects is largely restricted to studies of children who begin formal schooling at 6 years of age, and the measures of phoneme awareness used have typically lacked sensitivity for beginning readers. Our study addresses these issues by testing 4 to 6 year-olds (first 2 years of formal schooling in the United Kingdom) on a sensitive dynamic measure of phoneme awareness and tests of early literacy. There were significant effects of both age and schooling on the dynamic measure of phoneme awareness, word reading, spelling, and letter name knowledge, but there were no significant Age × Time interactions. This indicates that older children within this age group generally outperform their younger classmates (although they do not make faster progress) and that this advantage is developed prior to the start of school.     

Sensory processing, reading, IQ, and attention

Detection thresholds for two visual- and two auditory-processing tasks were obtained for 73 children and young adults who varied broadly in reading ability. A reading-disabled subgroup had significantly higher thresholds than a normal-reading subgroup for the auditory tasks only. When analyzed across the whole group, the auditory tasks and one of the visual tasks, coherent motion detection, were significantly related to word reading. These effects were largely independent of ADHD ratings; however, none of these measures accounted for significant variance in word reading after controlling for full-scale IQ. In contrast, phoneme awareness, rapid naming, and nonword repetition each explained substantial, significant word reading variance after controlling for IQ, suggesting more specific roles for these oral language skills in the development of word reading.     

Chicken or egg? Untangling the relationship between orthographic processing skill and reading accuracy

There is increasing evidence of a relationship between orthographic processing skill, or the ability to form, store and access word representations, and reading ability. Empirical research to date has not, however, clarified the direction of this relationship. We examined this question in a three-year longitudinal study of children from Grades 1 to 3. We included standard measures of orthographic processing skill, at both the lexical and sublexical level, and word reading accuracy, as well as controls of vocabulary, non-verbal reasoning, and phonological awareness. In all analyses, word reading predicted progress in acquiring orthographic processing skill, regardless of grade level or orthographic processing measure. In contrast, orthographic processing skill did not predict progress in word reading. Our results suggest that, between Grades 1 and 3, children acquire orthographic processing skill through their reading and that this ability, as characterized by the most common tasks used to date, does not play an independent role in supporting reading acquisition.     

Structure of preschool phonological sensitivity: overlapping sensitivity to rhyme,words, syllables,and phonemes

Phonological sensitivity is an important causal variable in reading acquisition; however, there is controversy concerning its nature. One view holds that sensitivity to various linguistic units reflects independent abilities, whereas another holds sensitivity to these units reflects one ability. We examined relations among sensitivity to words, syllables, rhymes, and phonemes in 149 older preschool children (4- and 5-year-olds) and 109 younger preschool children (2- and 3-year-olds) who completed eight measures of phonological sensitivity and measures of print knowledge. Confirmatory factor analyses of all combinations of word, syllable, rhyme, and phoneme factors found that a one-factor model best explained the data from both groups of children (CFIs >.98). Only variance common to all phonological sensitivity skills was related to print knowledge and rudimentary decoding. Findings support a developmental conceptualization of phonological sensitivity.     

Levels of phonological awareness in three cultures

This study focused on syllable phoneme onset levels of phonological awareness in relation to reading of Chinese and English in kindergarten and first-grade children from Xian (China), Hong Kong, and Toronto, cultures that differ substantially in approaches to reading instruction. English syllable awareness among native Chinese speakers was as good as or better than that among English speakers, indicating that the Chinese language may promote syllable-level awareness in children. Hong Kong children recognized significantly more words in both English and Chinese but were significantly poorer than the Xian children in both syllable and phoneme onset deletion tasks, suggesting that Pinyin training (given in Xian only) may promote phonological awareness even at the syllable level. In both Xian and Hong Kong, measures of syllable awareness consistently predicted Chinese character recognition better than did phoneme onset awareness. In contrast, English word recognition was predicted differently by syllable and phoneme onset awareness across cultures. These results underscore the roles of both language and writing system in understanding levels of phonological awareness.
