Phonological skills and reading comprehension

In the present study the mainfocus is on the impact of phonologicalawareness on reading comprehension. The studyinvolved 1300 children in Grade 1. Syllableawareness, phoneme awareness, word decodingand reading comprehension were each assessedwith two or three subtests. The results wereanalyzed by structural modeling. Due to themarked skewness observed for some of themanifest variables, separate analyses wereperformed for students with average worddecoding performance and for students with poorword decoding. Both among average and poordecoders, phonological awareness had a directimpact on reading comprehension, indicatingthat phonological factors play an independentrole in the processing of text. One possibleway to explain this observation is that atleast two critical factors in comprehension,vocabulary and short-term memory, are bothdetermined in part by phonological ability. Itmight also be the case that phonologicalawareness partly reflects metacognitiveprocesses assumed to be involved in readingcomprehension.     

Phonological,visual and temporal processing in adults with and without reading disability

The primary goal of this study was to comparethree theoretical accounts of readingdisability (RD) by simultaneously studyingphonological, visual, and temporal processingskills. Adults with and without RD werecompared on measures of phonological processingwith the Auditory Analysis Test (AAT) and theWoodcock Reading Mastery Test (WRMT-R) WordAttack subtest. Visual processing was assessedwith the Useful Field of View test (UFOV®)and the Frequency Doubling Technology Perimeter(FDT). The Repetition Test was used toevaluate temporal processing skills. Adultswith RD evidenced poorer phonological andtemporal processing skills than did adultswithout RD, but no significant differencesbetween the groups were found in visualprocessing. Future research is needed toclarify the relations among phonological,visual, and temporal skills and the roles theyplay in RD. The trajectory and co-existence ofdeficits throughout development, as well as howspecifically such impairments affect reading,warrant further investigation.     

Early linguistic abilities and reading development: A review and a hypothesis

This article is concerned with aspects of phonological processing and linguistic awareness that may set the stage for initial reading development. The aims are first to provide a current review of phonological processes (both underlying and metaphonological) that have been found to be associated with initial reading achievement, secondly to present a new hypothesis relating differences in the nature of phonological representations in the lexicon to the development of phonological awareness and other phonological processes. The hypothesis is concerned withdistinctness of phonological representations, i.e. the separateness of phonological representations. Phonological representations of high distinctness are distinguished from other representations by many features. The distinctness hypothesis is compared to the lexical restructuring hypothesis which suggests that lexical representations gradually become increasingly segmental between one and eight years of age. Implications of each hypothesis (emphasizing the distinctness hypothesis) for the development of language abilities and reading are presented, along with suggestions regarding future research directions.     

Language specific speech perception and the onset of reading

In two studies the relationship between theonset of reading and language specific speechperception, the degree to which native speechperception is superior to non-native speechperception, was investigated. In Experiment 1with children of 4, 6, and 8 years, languagespecific speech perception occurred maximallyat 6 years and was positively related toreading ability for age and languagecomprehension level. In Experiment 2, with anexpanded range of ages and various stimulus andtask changes, the relationship between readingand language specific speech perception stillheld, and maximal language specific speechperception occurred around the onset of readinginstruction for three different sets of speechcontrasts, but not for a control set ofnon-speech contrasts. The results show thatlanguage specific speech perception is alinguistic rather than an acoustic phenomenon.Results are discussed in terms of early speechperception abilities, experience with oralcommunication, cognitive ability, readingability, alphabetic versus logographiclanguages, phonics versus whole word readinginstruction, and the effect of age versusinstruction.     

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.     

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.

Phonological processes as predictors of specific reading skills in children at risk for reading failure

Children at risk for reading disability were evaluated as kindergartners and again as first graders to determine (1) intercorrelations among phonological processing tasks and (2) the relationship of such tasks to word identification and word attack. With IQ controlled, there were no intercorrelations among measures of phonological awareness, phonetic recoding in working memory, and phonological recoding in lexical access. Thus, these results failed to substantiate the concept of a general phonological processing ability. Partial correlations controlling for IQ revealed no relationship between reading and phonological awareness or phonetic recoding in working memory. In contrast, lexical access measures were significantly, albeit moderately, correlated with word identification but not word attack. Word attack and word identification were predicted by different combinations of variables. These results suggest that lexical access ability is an important factor in reading acquisition and that different combinations of phonological processes may be related to different aspects of reading.This research was supported by PHS grant HD 21887 to Bowman Gray School of Medicine and by PHS Grant NS 19413 to UNC-Greensboro Subcontract to Bowman Gray School of Medicine.     

A reading-level match study of phonemic processes underlying reading disabilities in a transparent orthography

The current study examined the relationship in Spanish (i.e., a transparent orthography) between different levels of phonological awareness and reading disabilities. In addition, the strategies used by the children when they resolved phoneme segmentation and reversal tasks were analyzed. A sample of 133 subjects were selected and organized in three different groups: (1) A group of 45 reading-disabled children, (2) A comparison group of 44 normal readers matched in age with the reading disabled, and (3) A reading level match group of 44 younger normal readers at the same reading level as the reading disabled. Three phonological awareness tasks were used to measure levels of intrasyllabic and phonemic awareness. The reading disabled group was equivalent to the younger reading level-matched control group in the odd-word-out task. However, there were differences in the phonemic tasks (e.g., phoneme segmentation and reversal) because the reading disabled group performed more poorly than the younger children. Overall, the children matched in age with the reading disabled group were superior in all phonological awareness tasks. There were differences between the groups when the strategies used by the children were analyzed.     

The relationship of rapid serial naming and word reading in normally developing readers: An exploratory model

Even though researchers have established that rapid serial naming (RSN), or the ability to name within a restricted category of visual stimuli quickly, is a significant predictor of word reading, the predictive nature of RSN is not well understood. To investigate the relationship of RSN and other variables thought to contribute to beginning word reading (phonological awareness, orthographic knowledge, memory span, processing speed, and articulation), a preliminary/exploratory model of word reading was developed and then tested by path analysis. Results indicated that no variable in the model could fully `explain' RSN; processing speed, but not articulation, contributed to RSN performance. RSN and orthographic knowledge were significantly related, but this relationship was due to the effects of processing speed. In terms of their unique contributions to the variance in word reading, RSN, phonological awareness, and orthographic knowledge were independent of each other. While these results pertain only to normal readers and are preliminary in nature, they may provide a basis for a clear interpretation of similar studies conducted with both normal and dyslexic readers.     

The relation between reading ability and morphological skills: Evidence from derivational suffixes

The English orthography represents both phonemes and morphemes, implying that sensitivity to each of these units could play a role in the acquisition of decoding skills. This study offers some new evidence about sensitivity to morphemes and the decoding skills of American children in grades three to six. It focuses on knowledge of derivational suffixes, which is examined with sentence completion and sentence acceptability tasks that manipulate the suffixes in real words (e.g., electric, electricity) and nonsense derived forms (e.g., froodly, froodness). Both written and spoken materials are considered over the course of two experiments in which the children also received various reading tests, as well as tests of phonological awareness, vocabulary and intelligence. The results indicate that knowledge of derivational suffixes increases with grade level, along with decoding ability and phoneme awareness. Path analyses further reveal that, although there is a consistent correlation between performance on the derivational suffix materials and phoneme awareness and decoding ability, performance on the derivational suffix materials makes an independent and increasing contribution to decoding ability throughout the higher elementary grades.     

Phonological knowledge and naming ability in children with reading disability

Children who are poor readers have difficulty naming pictured objects. Their naming difficulty could be a result of inadequate representations of the phonology of words, inadequate processing of those representations, or both. In this study, third-grade good and poor readers were tested on object naming, and, in cases of naming failure, forced-choice recognition tasks were used to probe their knowledge of the phonology of the object names. The two reading groups showed no differences in their ability to select the initial phonemes or rhymes of object names they had not produced spontaneously. Moreover, initial phoneme prompts were helpful for both reading groups. The children differed, however, in their ability to produce words after being given rhyme information. The results indicated that, except in the ability to manipulate explicitly phonological information, the poor readers; performance was qualitatively similar to that of the good readers. It is suggested that training in phonological analysis may help poor readers overcome the deficiencies in establishing and processing phonological representations that lead to their quantitative deficit in object naming.     

Phonological awareness predicts activation patterns for print and speech

Using fMRI, we explored the relationship between phonological awareness (PA), a measure of metaphonological knowledge of the segmental structure of speech, and brain activation patterns during processing of print and speech in young readers from 6 to 10 years of age. Behavioral measures of PA were positively correlated with activation levels for print relative to speech tokens in superior temporal and occipito-temporal regions. Differences between print-elicited activation levels in superior temporal and inferior frontal sites were also correlated with PA measures with the direction of the correlation depending on stimulus type: positive for pronounceable pseudowords and negative for consonant strings. These results support and extend the many indications in the behavioral and neurocognitive literature that PA is a major component of skill in beginning readers and point to a developmental trajectory by which written language engages areas originally shaped by speech for learners on the path toward successful literacy acquisition.

Phonological processing and emergent literacy in younger and older preschool children

Phonological awareness, phonological memory, and phonological access to lexical storage play important roles in acquiring literacy. We examined the convergent, discriminant, and predictive validity of these phonological processing abilities (PPA) in 389 3-, 4-, and 5-year-old children. Confirmatory factor analysis supported the validity of each PPA as separate from general cognitive ability and separate from each other. Multigroup structural equation modeling (SEM) with mean structure demonstrated that older preschoolers have better developed latent PPA than younger preschoolers but that the structure of PPA is equivalent. RAN was found uniquely associated with letter knowledge and text discrimination in younger preschoolers, and PA was found uniquely associated with word reading skills in older preschoolers. Finally, general cognitive ability was only indirectly associated with emergent literacy via PPA. These results highlight the importance of PPA in the early literacy development of English-speaking preschool children.     

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.     

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.     

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.     

Investigating reading development in atypical populations: The case of Williams syndrome

This paper presents a review of currentknowledge concerning the reading skills ofchildren and adults with Williams syndrome. The paper begins by highlighting themethodological issues surrounding research onreading in atypical populations and discussesthe issue of comparison groups. It proceeds toreview evidence from studies that havedescribed the reading profile observed inWilliams syndrome in relation to the documentedcognitive and linguistic profile, andspecifically examines the relationship betweenreading and phonological skills. The paperadvocates a more dynamic developmental approachto the study of reading in atypical populations.     

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.
