Components of phonological awareness

The factorial structure underlying different types of tasks within the domain of phonological awareness was examined in two studies. Large sample sizes allowed for sensitive differentiation of constructs. In the first study, 128 preschool children without any experience of formal reading instruction were tested with a battery of tasks intended to tap various aspects of phonological awareness: rhyme recognition, syllable counting, initial-phoneme matching, initial-phoneme deletion, phoneme blending, and phoneme counting. Three basic components were extracted in a principal component analysis: a phoneme factor, a syllable factor and a rhyme factor. Cross-tabulations indicated considerable dissociation between performance on phoneme, syllable, and rhyme tasks. The structural relationships were replicated on a much larger sample (n=1509) in the second study. Subjects in this study were one year older and were attending grade 1 thus providing an opportunity to test their reading achievement. Multiple regression analyses demonstrated that the phonemic factor was by far the most potent predictor. However, the rhyming factor made an independent (although small) contribution to explaining the reading variance. Among the phonemic tasks, phoneme identification proved to be the most powerful predictor.     

Training phonological awareness: a study to evaluate the effects of a program of metalinguistic games in kindergarten

A phonological awareness program was evaluated in a small-scale study using thirty eight children from three intact kindergarten classes at an American school on the outskirts of London. The average age of the children was five years four months. There was one experimental class and two control classes. The experimental class received a Danish training program of metalinguistic games and exercises. One control class used a kindergarten reading and writing program called Success in Kindergarten Reading and Writing which incorporates phonological awareness skills, but in an informal way. The other control class followed the normal kindergarten program. The results showed that the children in the experimental group and the Success in Kindergarten group had significantly greater gains in reading and spelling measures given at the end of the year. They also did better on six of the metalinguistic tests, with the experimental group showing significantly greater gains in all the tests of phoneme awareness than the other two groups. The implications of a formal versus informal phonological awareness training program are discussed.     

The effects of morphological versus phonological awareness training in kindergarten on reading development

The aim of this study was toinvestigate the long-term effects of twodifferent training programs in kindergarten onreading development. One group received aprogram focusing on the phonological structureof words, while a second group received aprogram focusing on morphology. Both groupsalso had some print exposure focusing onphonological or morphological elementsrespectively. During their last pre-schoolyear, participants received training for 30minutes per week for a total of 17 weeks. Acontrol group received no intervention but wasregularly visited by the researcher and hadextensive print exposure. Both trained groupsshowed improvements in phonological,morphological and reading skills in comparisonto the Control Group. The effects of trainingvaried according to mother's educational level:Children of relatively highly educated mothersentered the pre-school training with betterdeveloped metalinguistic abilities thanchildren of less well educated mothers.Significant interactions between the groups andthe mother's educational level, for some of theschool reading measures, indicated thatdifferent training programs had differenteffects on different groups of children.Children of poorly educated mothers profitedthe most from metaphonological training whilechildren of highly educated mothers profitedthe most from metamorphological training.     

Phonemic awareness,naming, visual symbol processing,and reading

This study examined differences between adequate and poor readers in phonemic awareness, rapid continuous and confrontation naming, and visual symbol processing. It also investigated which of these skills make independent contributions to word recognition, pseudoword reading, and reading comprehension. Subjects were 170 school referrals of average intelligence, aged 6 to 10 years. The strongest differentiators of adequate and poor readers, with IQ and reading experience controlled, were phonemic awareness, naming speed for letters and pictured objects, and visual symbol processing. Letter naming speed made the largest independent contribution to word recognition, phonemic awareness to pseudoword reading, and object naming speed to reading comprehension. Confrontation picture naming accounted for minimal variance in reading skills, when IQ was controlled. It was concluded that tasks of naming speed, phonemic awareness, and visual symbol processing are valuable components of a diagnostic battery when testing children with possible reading disability.     

Distinctive patterns of relationship of phonological awareness and working memory with reading development

The purpose of this study was to assess the contributions of specific components of verbal and nonverbal working memory and of phonological awareness to the prediction of reading achievement. One hundred and three children from grades 1, 2, and 3 were administered a measure of phonological awareness, four measures of working memory, four measures of academic achievement, and a measure of verbal intelligence. Separate multiple regression analyses controlling for the effects of age, sex and verbal intelligence showed that tests of verbal memory and of direct recall significantly predicted reading and spelling achievement whereas tests of backward recall significantly predicted only pseudoword identification. Phonological awareness was also found to relate significantly to reading and spelling achievement even when working memory was partialled out. Thus, phonological awareness and measures of working memory predicted specific and significant amounts of variance in reading and spelling achievement. Further, none of these measures were specifically related to arithmetic achievement. The specific roles of phonological awareness and working memory in reading development are examined in the discussion.     

Levels of phonological awareness in preliterate and literate Spanish-speaking children

Evidence of phonological awareness levels usually comes from English-speaking children. The evidence in Spanish is scarce. The present study examined the phonological awareness of syllables, onsets–rimes, and phonemes, extending the Treiman and Zukowski (1991) results to preliterate and literate Spanish-speaking children. The sample comprised preschoolers, kindergarteners and first-graders. Children found syllables easier than onset–rime units, and onset–rime units easier than phoneme units (Experiments 1 and 2). Preliterate children found ending units easier than beginning units. However, literate children were best at initial linguistic units, particularly initial syllables. Results on the phonological awareness task and on the masked priming lexical decision task support that the phonological awareness development is sensitive to the orthographic units used by children from the time they begin to read (Experiment 3). For all children, initial continuant consonants were easier than stop consonants.     

Phonological skills and comprehension failure: A test of the phonological processing deficit hypothesis

Shankweiler and colleagues argue that text comprehensionproblems in young children arise from phonological processingdifficulties. Their work has focused on children with poor wordreading ability. We investigated this hypothesis for children whoexperience comprehension difficulties in the presence of age-appropriate word reading skills. We found that good and poorcomprehenders performed comparably on various measures ofphonological processing and differed on a task that made greaterdemands on working memory, Bradley and Bryant's odd-word-outtask. In a final study, hierarchical regression analyses supportedthis distinction: the odd-word-out task was a strong predictor ofreading comprehension performance even after IQ, vocabulary and single word reading had been controlled for, but a lessmemory-dependent phonological task was not. These studiessupport previous work which indicates that poor comprehenders'problems arise from higher-level processing difficulties.     

The role of phonological and syntactic awareness in second-language reading: The case of Spanish-speaking learners of French

Spanish-speaking learners of French, aged 9 to 11 years old, were tested after approximately 7months of French instruction to explore the contribution of phonological and syntactic awareness in L2 in 4 components of L2 reading, taking oral competence in L2 andreading in L1 into account. Phonological tasksin L2 better explain decoding. Word recognitionthrough the visual route is best explained bythe corresponding ability in L1. Sentencecomprehension is best explained by oralcompetence in L2, although it is stronglycorrelated with syntactic awareness. Finally,text comprehension is explained by thecorresponding ability in L1, althoughcorrelations with syntactic awareness and oralcompetence are strong. Theoretical implicationsare derived from these findings, and questionsrelative to the subjects' age and level ofbilingualism as well as methodological issuesare discussed.     

Morphological analysis,phonological analysis and learning to read French: a longitudinal study

This paper presents a longitudinal study, from kindergarten to secondgrade, which aims to examine the relationship between morphologicalanalysis, phonological analysis and learning to read. Three phonologicalawareness tasks, five derivational and four inflectional subtests wereadministered to fifty children at each of the three levels. Evolution ofperformance was analyzed through the three years. Data showed that withthe exception of two subtests, performance increased from kindergarten tofirst grade and from first grade to second grade, without reaching ceilingperformance in second grade, at least for morphological subtests. Linksbetween morphological and phonological analyses were very strong: inparticular, syllable segmentation was highly correlated with themorphological subtests in kindergarten while phonemic segmentation wascorrelated with morphological subtests in first and second grade. Therewere also strong links between morphological analysis and reading.Regression analyses showed that while phonological awarenessexplained a major part of variance in first grade, both phonologicaland morphological scores explained significant part of variance of bothdecoding and comprehension reading scores in second grade. Thus, thislongitudinal study contributes to the evidence of a link between bothphonological and morphological analysis and learning to read French.     

Letter names, letter sounds and phonological awareness: an examination of kindergarten children across letters and of letters across children

In this study 149 kindergarten children were assessed for knowledge of letter names and letter sounds, phonological awareness, and cognitive abilities. Through this it examined child and letter characteristics influencing the acquisition of alphabetic knowledge in a naturalistic context, the relationship between letter-sound knowledge and letter-name knowledge, and the prediction of Grade 1 phonological awareness and word identification from these variables. Knowledge of letter sounds was better for vowels and for letters with consonant–vowel names than for those with vowel–consonant names or names bearing little relationship to their sounds. However, there were anomalies within each category reflecting characteristics of the individual letters. Structural equation modelling showed that cognitive ability, comprising receptive vocabulary, non-verbal reasoning, rapid automatized naming of colours, and phonological memory significantly contributed to alphabetic knowledge and phonological awareness. In turn, letter-name knowledge but not phonological awareness predicted letter-sound knowledge and subsequent reading skill.This research was supported by a grant from the Social Sciences and Humanities Research Council of Canada to the first author.

Early phonological and lexical markers of reading disabilities

Phonological and lexical characteristics of 30-month-old children’s spontaneous language samples were examined as indicators of later reading outcome. Participants were 27 children, 10 children with reading disability and 17 children without reading disability. Of the non-disabled readers, 7 were at high familial risk for reading disability, and 10 came from families with no history of reading difficulties. Children later identified as reading disabled at second grade and beyond demonstrated narrower lexical diversity and simpler phonological forms as compared to the normal reading participants. Implications of reduced phonological complexity in the productive lexicons of reading disabled children are discussed.     

Structural invariance in the associations of naming speed,phonological awareness,and verbal reasoning in good and poor readers: A test of the double deficit hypothesis

The associations of multiple measures of speeded naming, phonological awareness, and verbal intelligence with word reading were examined in 51 poor readers and 74 good readers in third and fourth grade. Structural equation modeling was used to determine the extent to which these two groups exhibited structurally invariant patterns of associations among the constructs. Results revealed that for poor readers, both speeded naming and phonological awarencess were significantly associated with word reading, but verbal intelligence had no association with it. In contrast, for good readers, phonological awareness and verbal intelligence were significantly associated with word reading, but naming speed was not. Findings are discussed in light of the double deficit hypothesis.     

Persistence of phonological awareness deficits in older children with dyslexia

Three groups of children with dyslexia, with mean age 8, 13 and 17 years, together with three groups of normally achieving children matched for age and IQ with the dyslexic groups, undertook tests of sound categorization and phoneme deletion. The design allowed comparison not only across chronological age but also across reading age. The children with dyslexia performed significantly worse even than their reading age controls on both tasks. Indeed, overall performance of the 17 year old children with dyslexia was closest, but inferior, to that of the 8 year old controls. Since the sound categorization task was designed to minimize working memory load, the results extend previous findings on the phonological awareness deficits in dyslexia by dissociating the deficit from memory load and by showing that it persists at least into late adolescence.     

Why the timing deficit hypothesis does not explain reading disability in adults

It has been proposed that the phonological coredeficit that is linked to reading failure hasas its underlying cause a deficit in temporalprocessing. In a multivariate investigationdesigned to examine the temporal processingdeficit hypothesis, thirty reading-disabled(RD) adults, thirty-two normally achievingadults and thirty-one normally achievingchildren (reading-level controls) wereadministered a comprehensive battery thatincluded a wide range of timing tasks, inaddition to reading and phonological measures. Although adults with RD displayed overallperformance that was below that of normallyachieving adults on most of the timing tasks,their performance was not differentiallyinfluenced by rate of stimulus presentation. Although the RD adults displayed the typicalpattern of impaired phonological awareness andpseudoword reading relative to reading-levelmatched children, the reading-disabled adultsoutperformed the children on the timing tasks. Finally, with the exception of continuousnaming, the timing tasks shared little variancewith phonological sensitivity and contributedlittle unique variance to word reading. Although these findings undermine the timingdeficit hypothesis, they do provide evidencefor the involvement of naming deficits inreading disability.     

Developing phonological awareness and word recognition skills: A two-year intervention with low-income,inner-city children

Low-income, inner-city children were involved in a two-year intervention delivered in the regular classroom by regular classroom teachers to develop phonological awareness and word recognition skills. For the treatment children, an 11-week phoneme awareness program in kindergarten was followed by a first grade reading program (extended to grade 2 for some children) that emphasized explicit, systematic instruction in the alphabetic code. Control children participated in the school district's regular basal reading program. Both groups participated in a phonetically-based spelling program mandated by the district. At the end of grade 1, treatment children (n = 66) significantly outperformed control children (n = 62) on measures of phonological awareness, letter name and letter sound knowledge, and three measures of word recognition, and reached marginal significance (0.056) on a fourth. They also significantly outperformed the control children on two measures of spelling. One year later, at the end of grade 2, the treatment children (n = 58) significantly outperformed the control children (n = 48) on all four measures of word recognition. For the groups as a whole, there were no differences on the one measure of spelling readministered at the end of grade 2. However, there were significant differences in spelling between the treatment (n = 16) and control children (n = 13) who remained in the bottom quartile of spellers at the end of grade 2 when partial credit was given for phonetically correct spelling, and significant differences in reading favoring these treatment children on all four measures of word recognition.     

The structure of phonological awareness in European Portuguese: A study of preschool children

The importance of phonological awareness for the future learning of written language has been widely recognized, but there is still some debate as to whether syllabic, intrasyllabic, and phonemic awareness are independent skills or manifestations of the same general skill. Consequently, the objective of this study was to test the independence of phonological awareness at the syllable, rhyme, and phoneme levels. The study involved the participation of 256 children in their last year of preschool. The children completed 18 phonological awareness tasks. Three models were tested: a one-factor model (phonological awareness), two-factor model (supraphonemic unit awareness and phonemic awareness) and three-factor model (syllabic, intrasyllabic, and phonemic awareness). The results indicated that the three-factor model had the best fit, suggesting the relative independence of syllable, rhyme, and phoneme awareness. These results have important implications for assessing and intervening in sound sensitivity and identification skills in the preschool period.     

Levels of phonological awareness and learning to read

The paper reports studies of segmentation performance by a Nursery group of children, who had not yet started to learn to read, and by Primary 1 and 2 groups, who were in the early stages of learning by a standard method of whole word acquisition combined with letter-sound learning. Rhyme and alliteration production tasks were applied, together with segmentation tasks requiring division of monosyllabic words or non-words of simple or complex structure into two parts, three parts, or as many parts as possible. Performance was related to the hierarchical model of the syllable which distinguishes a two-dimensional (2D) level (onset/rime), a three-dimensional (3D) level (initial consonants, vowel, terminal consonants) and many-dimensional (nD) level (phonemes). The hypothesis that phonological awareness (PA) normally develops down the hierarchy, from larger to smaller units, predicts that segmentation ability should emerge in the sequence 2D 3D nD. In practice, the reverse of this order was found. The results are discussed in relation to theories of the relationship between literacy development and the different levels of PA.     

The relationship between phonological awareness and the development of orthographic representations

A training study was conducted to investigatethe relationship between phoneme segmentationability and the development of orthographicrepresentations. Five-year-old children withvarying degrees of phoneme segmentationability were taught to read ten new words byrepeated presentation of the words onflashcards. It was found that those childrenwho were most well equipped to perform phonemesegmentation tasks acquired this new readingvocabulary significantly faster than those whowere less phonemically aware. A series ofpost-tests was implemented to discover thenature of the internal orthographicrepresentations which the children had createdfor the words learned. The results of thesepost-tests demonstrated that the children whowere most phonemically aware had alsointernalised the most detailed orthographicrepresentations, despite needing fewerlearning trials. Salient letters fororthographic storage were predictable from thechildren's phoneme segmentation abilities. This paper provides strong support for thethesis that phonemic awareness is related toorthographic storage as well as alphabeticreading techniques.     

Developmental changes in the contributions of phonological processing skills to Chinese character reading and arithmetic

This study examined the associations of phonological processing skills with reading and arithmetic ability in Chinese kindergartners (Mage = 5.56 years), third graders (Mage = 9.72 years), and fifth graders (Mage = 11.75 years) (N = 413) of Han descent. The results showed that phonological awareness and rapid automatized naming (RAN) showed stronger relations than phonological memory with reading and arithmetic across grades. Furthermore, the associations of phonological awareness and RAN with reading were much stronger in kindergartners than in primary school children, whereas their relationships with arithmetic remained stable across grades. Among phonological skills, phonological awareness has a unique influence on arithmetic that is independent of Chinese character reading in third-graders and kindergartners. In contrast, RAN uniquely explained the variation in arithmetic skills in fifth graders when reading was statistically controlled for. These findings have important implications for understanding the co-development of reading and arithmetic across grades and raise the possibility of training in phonological awareness and/or RAN to help children at risk for learning disabilities.     

Screening of phonological awareness in the early elementary grades: an IRT approach

The purpose of the present study was to explore the possibilities for the assessment of growth in phonological awareness of children in kindergarten and first grade. Phonological awareness was measured using four sets of items involving rhyming, phoneme identification, phoneme blending, and phoneme segmentation. The results of an exploratory factor analysis and analyses conducted within the framework of item response theory showed one latent ability to underlie the different sets of items, which nevertheless differed in difficulty. Analyses in terms of the children’s ability further showed the phonological awareness measures to be sensitive to growth. The amount of information supplied by the different sets of items depended on the children’s level of ability. The conclusion that it is possible to accurately monitor the development of children’s phonological awareness in the early elementary grades appears to be justified, and this possibility opens up new perspectives for the early screening for reading problems and dyslexia.
