Acquisition of reading and written spelling in a transparent orthography: Two non parallel processes?

Reading and written spelling skills for words and non-words of varying length and orthographic complexity were investigated in normal Italian first and second graders. The regularity and transparency of the mapping between letters and phonemes make Italian orthography an unlikely candidate for discrepancies between reading and spelling to emerge. This notwithstanding, the results showed that reading accuracy is significantly better than spelling. The difference is particularly striking in first graders, but it is still evident in 2nd graders, though most strongly on non-words. The data show that reading and written spelling are non parallel processes and that the developmental asynchrony reflects a partial structural independence of the two systems.     

Subtypes of reading disability in a shallow orthography: a double dissociation between accuracy-disabled and rate-disabled readers of Hebrew

Whereas most English language sub-typing schemes for dyslexia (e.g., Castles & Coltheart, 1993) have focused on reading accuracy for words varying in regularity, such an approach may have limited utility for reading disability sub-typing beyond English in which fluency rather than accuracy is the key discriminator of developmental and individual differences in reading ability. The present study investigated the viability of an accuracy/fluency-based typology in a regular orthography, pointed Hebrew. We sought evidence of true or “hard” accuracy/rate subtypes in the strict (double dissociation) sense of selective impairment on only one dimension in the presence of normal levels of performance on the other dimension. In a nationally representative sample of fourth graders, we were able to identify a specific accuracy-disabled sub-group as well as an equally specific rate-disabled subgroup. Validating this subdivision, we show that the nature of reading performance in these subgroups and their converging cognitive/linguistic profiles are unique and distinctive on variables other than the measures used to define them. While the rate-specific disability appeared to reflect a general deficit in speed of processing affecting reading rate, and rapid automatized naming of print-related material, the accuracy-only disability subgroup displayed selective deficits in phonological awareness and morphological knowledge. Biosocial, demographic, and instructional factors, furthermore, did not explain the sub-group differences. It appears that both these subtypes are equally prevalent each counting close to 10% of the population.     

Correlates of early reading performance in a transparent orthography

A cross-sectional study was conducted with 83first – and 81 fourth graders at the end of theschool year to examine factors accounting forearly reading performance in Finnish, atransparent orthography with a clear mapping ofphonemes onto graphemes. Measures for bothgrades included reading comprehension, phonemeawareness, and object- and digit naming.Additionally measures of skills in morphology,spelling and a screening battery wereadministered to the first graders. The sets ofmeasures accounted for 56% of the variance inreading performance in first grade and 64% infourth grade. Phoneme awareness was stronglyrelated to reading performance and spelling atthe end of first grade, but only forless-skilled readers in fourth grade. Theseresults suggest a larger role for phonemeawareness for children learning a transparentorthography than has been suggested in earlierstudies. At the same time, listeningcomprehension contributed more strongly tofirst-grade reading performance than has beenreported for children learning to readEnglish.     

The role of letters and syllables in typical and dysfluent reading in a transparent orthography

The role of letters and syllables in typical and dysfluent second grade reading in Finnish, a transparent orthography, was assessed by lexical decision and naming tasks. Typical readers did not show reliable word length effects in lexical decision, suggesting establishment of parallel letter processing. However, there were small effects of word syllable structure in both tasks suggesting the presence of some sublexical processing also. Dysfluent readers showed large word length effects in both tasks indicating decoding at the letter-phoneme level. When lexical access was required in a lexical decision task, dyslexics additionally chunked the letters into syllables. Response duration measure revealed that dysfluent readers even sounded out the words in phoneme-by-phoneme fashion, depending on the task difficulty. This letter-by-letter decoding is enabled by the transparent orthography and promoted by Finnish reading education.

Semantic effects as a function of reading skill in word naming of a transparent orthography

The highly transparent Turkish orthography was employed to examine imageability in relation to level of skill in two experiments. In experiment 1, previously skilled readers (n = 24)named 40 high frequency and 40 low frequency words manipulatedfactorially with imageability. A significant main effect was onlyfound for frequency. In experiment 2, a total of 44 adult Turkishreaders (16 very skilled and 28 skilled) named the same stimulias in experiment 1. The results showed an expected main effectfor skill and frequency. However, whilst the main effect forimageability was nonsignificant, a 2-way interaction of skill byimageability and a 3-way interaction of skill by imageability byfrequency were found to be significant. Very skilled readersnamed high imageable low frequency words significantly fasterthan matched low imageable low frequency words. Insofar as poorreaders are concerned the results are contradictory to previousfindings in English whilst data from highly skilled participantsare in line with those reported for skilled readers for English.Implications of these findings on the existing literature arediscussed.     

A longitudinal investigation of the double dissociation between reading and spelling deficits: the role of linguistic and executive function skills

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.     

Evidence for the early emergence of the simple view of reading in a transparent orthography

The main aim of the present study was to empirically test the emergence of the Simple View of Reading (SVR) in a transparent orthography, and specifically in Greek. To do so, we examined whether the constituent components of the SVR could be identified in young, Greek-speaking children even before the beginning of formal reading instruction. Our investigation focused on Kindergarten children and examined the dissociation of decoding-related and language comprehension skills using Exploratory Factor Analysis. All children were administered a battery of decoding-related and comprehension measures. The analysis demonstrated that comprehension and decoding-related measures loaded as distinct factors in young Greek-speaking children and that the two factors were weakly correlated. The present findings provide important support for the validity of the SVR framework as a model of reading skills acquisition in a language with a transparent orthography, such as Greek.     

Orthographic processing is a key predictor of reading fluency in good and poor readers in a transparent orthography

We used structural equation modeling to investigate sources of individual differences in oral reading fluency in a transparent orthography, Russian. Phonological processing, orthographic processing, and rapid automatized naming were used as independent variables, each derived from a combination of two scores: phonological awareness and pseudoword repetition, spelling and orthographic choice, and rapid serial naming of letters and digits, respectively. The contribution of these to oral text-reading fluency was evaluated as a direct relationship and via two mediators, decoding accuracy and unitized reading, measured with a single-word oral reading test. The participants were “good” and “poor” readers, i.e., those with reading skills above the 90th and below the 10th percentiles (n = 1344, grades 2–6, St. Petersburg, Russia). In both groups, orthographic processing skills significantly contributed to fluency and unitized reading, but not to decoding accuracy. Phonological processing skills did not contribute directly to reading fluency in either group, while contributing to decoding accuracy and, to a lesser extent, to unitized reading. With respect to the roles of decoding accuracy and unitized reading, the results for good and poor readers diverged: in good readers, unitized reading, but not decoding accuracy, was significantly related to reading fluency. For poor readers, decoding accuracy (measured as pseudoword decoding) was related to reading fluency, but unitized reading was not. These results underscore the importance of orthographic skills for reading fluency even in an orthography with consistent phonology-to-orthography correspondences. They also point to a qualitative difference in the reading strategies of good and poor readers.     

Dyslexia speed problems in a transparent orthography

This study was intended to help clarify the nature of dyslexia in Spanish. A sample of 30 children, 8 to 16 years old, participated in this study. Dyslexic children were compared to two control groups, a chronological age-matched control group and a reading level-matched control group. Measures included nonword and pseudohomophone reading (phonological procedure), homophone choice (orthographic procedure), and phonological awareness tasks (syllabic, intrasyllabic, and phonemic level). For each task, accuracy (error percentage) and performance time were measured. Results showed a deficit in the dyslexic group on all the tasks, which was more evident when time was considered. With the results consistent with studies in other transparent orthographies such as Italian and German, speed problems seem to be more evident and relevant than accuracy problems in Spanish dyslexic children.

The double deficit hypothesis in the transparent Finnish orthography: a longitudinal study from kindergarten to Grade 2

We examined the double deficit hypothesis (Wolf & Bowers, 1999) and literacy development in a longitudinal dataset of 1,006 Finnish children who were nonreaders at school entry. A single phonological awareness (PA) deficit was a predictor of pseudoword spelling accuracy and reading fluency, and a single rapid automatized naming (RAN) deficit was a predictor of reading fluency. The group with both PA and RAN deficits experienced the most extensive reading and spelling difficulties. However, all groups included both poor and average Grade 2 readers and spellers. Poor letter knowledge and vocabulary, task avoidance, attention difficulties, hyperactivity, and lack of teaching at home were additional risk factors for reading and spelling problems, but their impact varied depending on the presence of PA and RAN deficits.     

Visual and phonological determinants of misreadings in a transparent orthography

Growth of word reading skills was examined in first and second year Italian school children by analysis of the pattern of reading errors. The study was designed to investigate the role of visual vs phonological similarities as causes of misreadings in a transparent orthography. The selection of reading material was tailored to permit a meaningful cross-language comparison with pre-existing findings on English-speaking children. The results showed that, in Italian as in English, spatially-related errors (such as confusingb andd) constituted a minor proportion of the total errors. Errors on vowel and consonant letters that are not spatially confusable accounted for the greater proportion of the total. Moreover, the co-occurrence of spatial and phonological confusability resulted in appreciably more errors than when either occurred without the other. Vowel position in the syllable had no systematic effect on errors. In beginning readers of Italian, consonant errors outnumbered vowel errors by a wide margin; the reverse pattern was found in previous studies on English-speaking children at the same level of schooling. It is proposed that differences between Italian and English in the phonological structure of the lexicon and in the consistency of grapheme-phoneme correspondences account in large part for the differences in quantity and distribution of the errors.     

The relation between morphological awareness and reading and spelling in Greek: a longitudinal study

The aim of this longitudinal study is to examine the contribution of morphological awareness to the prediction of reading and spelling in Greek. The target group (N = 404) consisted of children, aged 6–9 years at the start of the project, who learn literacy in Cyprus. Because there are no standardized measures of morphological awareness for Greek Cypriot children, morphological awareness measures were developed and validated. A concurrent analysis of the first wave of data collection showed that morphological awareness made a unique contribution to the prediction of reading and spelling in Greek. The longitudinal analyses showed that morphological awareness predicted performance in reading eight months later, even after partialling out grade level, verbal intelligence, phonological awareness and initial scores in reading and spelling. This study makes theoretical, empirical and practical educational contributions. It shows the long term and specific relation of morphological awareness with reading in Greek and establishes the plausibility of a causal link between morphological awareness and reading, which must be tested in further research using intervention methods. In practice, this study contributes valid measures for assessing morphological awareness in Greek as well as a new measure of spelling skill.     

The relationship between the phonological strategies employed In reading and spelling

This paper summarises a longitudinal study which examined the relationship between the abilities of young children to read and spell phonologically. Empirical evidence of Bryant and Bradley (1980) and Cataldo and Ellis (1988) to show that children acquire the ability to use a phonological strategy for spelling before the ability to use an equivalent strategy for reading is confirmed. Implications for the teaching of reading are discussed.     

Learning a transparent orthography at five years old: reading development of children during their first year of formal reading instruction in Wales

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.     

Invented spelling activities in small groups and early spelling and reading

Our aim was to assess the impact of an invented spelling programme conducted in small groups on children’s written language acquisition in Portuguese. We expected the experimental group to have better post-test results than the control group in spelling and reading. Participants were 160 preschool-age children who were randomly divided into an experimental and a control group. Their age, cognitive ability, knowledge of letters and phonological abilities were controlled. Children’s spelling and reading were evaluated in a pre- and a post-test. In-between, experimental group participated in an invented spelling programme in small groups and the control group in story readings. The experimental group showed better results in spelling and reading in the post-test than the control one. Different dynamics occurred in the small groups which had different impacts on children’s acquisitions. These results provide empirical support for the proposal that invented spelling should be incorporated into early literacy instruction.     

Lexical priming of nonword spelling in the regular orthography of Italian

In pronounced contrast to English, Italian orthography contains extremely regular sound-to-spelling correspondences and therefore Italian words could, in principle, be spelled perfectly correctly using nonlexical phoneme-to-grapheme conversion rules alone. If this were so, then there should be no lexical influence upon nonword spelling. However, the present experiment reports lexical priming effects for two inconsistently spelled segments in Italian words: Italian participants were more likely to spell the nonword tece as TECIE if they had just heard the word specie rather than pece and were more likely to spell the nonword cuodo as QUODO if they had heard the word quota rather than cuoco. These results suggest that Italian, despite its regular orthography, is not spelled purely nonlexically. It is argued that a dual-route model of spelling production can be applied to Italian.     

The development of spelling knowledge and its role in reading acquisition and reading disability

In contrast to the hypothesis that dyslexics possess phonological deficits that are neurological in origin, I suggest that the source of the deficit is primarily experiential--that dyslexics exhibit phonological deficits because they have not learned to read and spell in a way that develops their spelling knowledge so that it penetrates and comes to symbolize their phonological knowledge. Evidence from normal reading and spelling development as well as from comparisons of dyslexic and nondyslexic readers is offered to support this thesis.
