The importance of letter knowledge in the relationship between phonological awareness and reading

Previous correlational and experimental research has found a positive association between phonological awareness and reading skills. This paper provides an overview of studies in this area and shows that many studies have neglected to control for extraneous variables such as ability, phonological memory, pre‐existing reading skills and letter knowledge. The paper reports on the results of a longitudinal study that took account of these variables when examining the relationship between phonological awareness and reading for a group of children during their first two years at school. Children showed rhyme awareness before they began to read but were unable to perform a phoneme deletion task until after they had developed word‐reading skills. Concurrent and predictive correlations between phonological awareness scores and later reading were often significant and remained so after adjusting for verbal ability or phonological memory. Controlling for letter knowledge, however, reduced most correlations to nonsignificant levels.

A Cross-Linguistic Comparison of Children Learning to Read in English and Dutch.

The authors report on a cross-linguistic investigation of the reading skills of 6- to 11-year-old children of English (an opaque orthography) and of Dutch (a transparent orthography). Dutch children were relatively more accurate and faster than English children of the same age at reading words and nonwords and also faster to complete phoneme deletion tasks, but the language differences were smaller than expected and modified by age. The predictors of individual differences in reading were similar in the 2 languages; phoneme awareness (as measured by accuracy and response time measures) was a significant predictor of reading, whereas rapid naming of colors, animals, and objects was not. The authors conclude that phoneme awareness is a predictor of individual differences in reading skill in transparent as well as opaque orthographies.

The dissociation of word reading and text comprehension: Evidence from component skills

In this paper, we discuss the relative contribution of several theoretically relevant skills and abilities in accounting for variance in both word reading and text comprehension. We present data from the first and second waves of a longitudinal study, when the children were 7 to 8 years, and 8 to 9 years old. In multiple regression analyses, we show that there is a dissociation between the skills and abilities that account for variance in word reading, and those that account for variance in text comprehension. The pattern of results is very similar at both time points. Significant variance in comprehension skill is accounted for by measures of text integration, metacognitive monitoring, and working memory. By contrast, these measures do not account for variance in word reading ability, which was best accounted for by a phoneme deletion task. The implications of these findings for our understanding of the development of reading ability, children’s problems in text comprehension and for remediation will be discussed.

Alphabetic and nonalphabetic L1 effects in English word identification: a comparison of Korean and Chinese English L2 learners

Different writing systems in the world select different units of spoken language for mapping. Do these writing system differences influence how first language (L1) literacy experiences affect cognitive processes in learning to read a second language (L2)? Two groups of college students who were learning to read English as a second language (ESL) were examined for their relative reliance on phonological and orthographic processing in English word identification: Korean students with an alphabetic L1 literacy background, and Chinese students with a nonalphabetic L1 literacy background. In a semantic category judgment task, Korean ESL learners made more false positive errors in judging stimuli that were homophones to category exemplars than they did in judging spelling controls. However, there were no significant differences in responses to stimuli in these two conditions for Chinese ESL learners. Chinese ESL learners, on the other hand, made more accurate responses to stimuli that were less similar in spelling to category exemplars than those that were more similar. Chinese ESL learners may rely less on phonological information and more on orthographic information in identifying English words than their Korean counterparts. Further evidence supporting this argument came from a phoneme deletion task in which Chinese subjects performed more poorly overall than their Korean counterparts and made more errors that were phonologically incorrect but orthographically acceptable. We suggest that cross-writing system differences in L1s and L1 reading skills transfer could be responsible for these ESL performance differences.

Relation of dialect to phonological processing: African American Vernacular English vs. Standard American English

Standard American English (SAE) and African American Vernacular English (AAVE) dialects differ in emphasis and use of word-final consonant sounds, with some consonants and clusters that are fully pronounced in SAE reduced or absent in AAVE. In two studies, SAE and AAVE speakers (age 7–11) completed phoneme deletion tasks in which the position of the deleted phoneme was varied. In general, SAE speakers performed better on word-final deletions than on word-initial deletions, whereas AAVE speakers performed better on word-initial deletions than on word-final deletions. Also, phoneme deletion performance tended to correlate more strongly with reading ability among SAE speakers than among AAVE speakers. Implications for phonological reading instruction and for the use of phonological screeners to identify at-risk readers are discussed.

Phonological awareness and musical aptitude

The relationship between phonological awareness and musical aptitude in pre‐school children was examined. In Experiment 1, Turkish children, and in Experiment 2, American children performed various phoneme deletion tasks with words in their respective native languages and with pseudo‐words. They also did initial and final tone deletion tasks with snippets of melodies. Because none of these children knew how to read, both tasks were presumed to depend largely on pure auditory skills. In general, success in the different phoneme deletion tasks reflected the characteristics of the specific languages with which the children were familiar. In addition, in both experiments, children in the high musical aptitude group did much better on all tasks than those in the low musical aptitude group, showing that success in manipulating linguistic sounds was related to awareness of distinct musical sounds.

Phoneme awareness and pathways into literacy: A comparison of German and American children

Where American kindergartners are taughtletters and letter sounds, Germankindergartners are not; where American firstand second graders receive an eclectic blend ofwhole language, whole word and phonics-basedapproaches, their German counterparts aretaught by an intensive synthetic phonicsapproach. As a probe to the consequences ofthese pedagogical differences on the emergenceof phoneme awareness, this study administeredtwo tests of phoneme awareness tokindergarten-, first- and second-grade childrenin Germany and America, along with readingtests, the digit span test and a test of RANcolor naming ability. The American kindergartenchildren excelled on a phoneme identityjudgement and a phoneme deletion task that theGerman kindergartners found difficult. Theiradvantage held equally whether the manipulatedsound was a syllable onset or the initial partof a consonant cluster. The first and secondgraders surpassed the kindergartners in bothcountries; however, the German first and secondgraders equaled their American peers on bothtasks and both types of units. In addition,the German children were more accurate decodersof pseudowords by the end of second grade, andthe association between phoneme awareness andGerman decoding ability was weaker. Anincreased emphasis on phonics and the greatertransparency of the German alphabet arediscussed as possible factors in the decodingexcellence of the German second graders and itsdecreased association with phoneme awareness.The contrast between the American and Germankindergartners and the equivalence of the firstand second graders in the two countries areconsistent with a view that phoneme awarenessdevelops primarily as a product of literacyexposure.

The Relation between Phonological Awareness and Working Memory

Previous research has failed to show a relation between children's working memory and performance on the phonological sound categorization task (M. J. Snowling, C. Hulme, A. Smith, & J. Thomas, 1994). However, the test used to assess working memory in that experiment was more comparable to a short-term memory task, which assesses storage capacity, than to a working memory task, which has both storage and processing components. In the present study, we compared the predictive power of both types of memory tasks on 2 measures of phonological awareness, the sound categorization task and a phoneme deletion task, in 7- and 8-year-olds (mean age = 8 years 1 month). The children's reading ability was also assessed. Fixed-order multiple-regression analyses showed that the sound categorization task has a higher working memory demand than the phoneme deletion task: Working memory predicted independent variance in performance only on the sound categorization task. The short-term memory task did not account for significant independent variance in performance on either of the measures of phonological awareness.

Linguistic precocity and the development of reading: The role of extralinguistic factors

ABSTRACTThe language and literacy skills of 21 children (aged 6;6), who were selected for linguistic precocity at age 1;8, are reported here. Verbal abilities remained high, and in contrast to the findings at 4;6 (reported in Crain-Thoreson & Dale, 1992), reading achievement is now at a superior level. Overall, the results are consistent with a two-phase model of reading development, in which the second phase is more closely related to language ability than the first. Phonological awareness, as indexed by a phoneme deletion task, appears to emerge as a consequence, rather than a cause, of early reading. There also appears to be a complex relationship among early interest in reading, instruction, and reading development. Differences in child interest in books and book reading may evoke variation in literacy-relevant experiences.

Teaching prereading skills with a talking computer

The phonological awareness skills of nonreaders were trained using an oddity task (e.g., which word in the series ‘sit’, ‘fit’, ‘cat’ has the odd sound in its middle position). As training progressed, the basis of the oddity decision was shifted from rhyming, to consonant onsets, to consonant and vowel phonemes. The words were spoken by a DECtalk speech synthesizer. One of the experimental groups was given printed as well as computer generated speech feedback while the other was given just computer speech feedback. The alternative training control group based their oddity decisions on meaning rather than sound and was also given just computer speech feedback. Only children with low letter-sound knowledge showed pre-test to post-test gains in performance on a rhyming task compared to the control group, and these gains were not influenced by print feedback. In contrast, only children with high letter-sound knowledge, who were given print feedback during learning, showed pre-test to post-test gains in performance on a phoneme deletion task compared to the control group. These results indicate that a combination of high letter-sound knowledge and print feedback facilitates awareness of phonemes among children who cannot yet read or spell, but awareness of rimes is not facilitated by either high letter-sound knowledge or print feedback. Although consistent with bi-directional, causal models of phonological awareness and literacy, these results indicate that the definition of literacy employed by such models may require expansion. This new definition should include proto-literacy — knowledge of letter-sound and other print-sound relationships that are learned before becoming literate and that may influence the acquisition of awareness of some sub-syllabic units of speech.

Phonological awareness and spelling in normal children and dyslexics: The case of initial consonant clusters

We investigated phonological awareness and spelling skills among normal readers and spellers in Grades 1 and 2 and among dyslexics who scored at the same level as the normals on a standardized spelling test. Both normal children and dyslexics had difficulty with consonants in word-initial clusters in a phoneme recognition task and a phoneme deletion task. Also, both groups of children had trouble producing legal spellings of syllables with initial clusters, sometimes failing to represent the second consonants of the clusters. The dyslexics' phonological awareness and spelling skills were poorer than those of the younger normal children, but the two groups showed similar patterns of performance.

Processing Strategies in a Phoneme Deletion Task

The present study explores the factors underlying competence in a difficult consonant deletion task, using a sample of nine-year-old children whose development had been followed from the age of four. In particular it examines the factors governing use of phonological and orthographic strategies in the deletion task, and the relations between strategy use, current reading and spelling ability, and earlier phonological awareness skills. Processes in consonant deletion are then mapped on to current dual-route models of reading and spelling.
