Training in phonemic segmentation: The effects of visual support

Two experimental studies examined the effects of different types of phonemic segmentation training on phonemic segmentation, reading and spelling. Children with learning disabilities, who were weak in phonemic segmentation, were trained with the use of diagrams and alphabet letters, with alphabet letters only, or with no visual support at all (the control condition). For this purpose three computer-assisted training programs were developed. In the first experiment, 48 children were assigned to one of the three programs. The training period lasted five weeks. Although in each training program the children improved their phonemic segmentation skill, there were no significant differences among the three training programs. This result may have been influenced by the different types of feedback that were provided in the three training programs. In a second experiment, therefore, these differences in feedback were eliminated and 49 different children were trained with the same three programs. The results of this experiment, however, were the same as those of the first experiment. The finding that visual support had no beneficial effects could therefore not be attributed to differences in explicit feedback. It was concluded that with these children, in contrast to preschoolers, phonemic segmentation training using visual support does not have any advantage over auditory training alone. The results of this study indicate that preschoolers and children with reading and spelling problems cannot be treated in the same way. It underlines the importance of further examination of the problems that poor readers and poor spellers encounter in grasping the structure of spoken language.     

Relations Between Children's Invented Spelling and the Development of Phonological Awareness

The objective of this study was to assess the impact on phonological skills of a training program that was intended to lead preschool children to move from prephonetic spellings to early phonemic spellings. The participants were 30 preschool children who were divided into two groups (experimental and control groups) that were equivalent in terms of the children's intelligence, the number of letters with which they were familiar and the nature of their invented spelling. The intervention proved effective, inasmuch as the children in the experimental group moved to early phonemic spellings, whereas those in the control group did not. This conceptual evolution entailed enhanced performance in phonemic classification, segmentation and deletion tests, in which the children in the experimental group displayed a degree of progress which differed significantly from that achieved by the members of the control group.     

On the interaction between phonological awareness and reading acquisition: It’s a two-way Street

We have investigated the reciprocal influence of reading acquisition and phonemic awareness. Using a between-grades quasi-experimental design, we have found that learning to read is the most important factor that accounts for the drastic improvement of phonemic segmentation skills during the first year of schooling. On the other hand, we found that improving phonemic skills in kindergarten facilitated reading acquisition in children at risk for developing reading disorders. We suggest that, for most children, exposure to the alphabet automatically triggers phonemic awareness, which is a necessary condition for efficient acquisition of reading. However, the emergence of phonemic awareness requires a previously developed sensitivity to phonology, which in some children may be absent. The present data suggest that, if phonological skills are absent, they may be developed in preschoolers by explicit training, thereby preventing failure in reading acquisition.     

Name-writing proficiency, not length of name, is associated with preschool children's emergent literacy skills

The goals of this study were twofold: first, to examine whether preschool children's name-writing proficiency differentiated them on other emergent reading and writing tasks, and second, to examine the effect of name length on preschool children's emergent literacy skills including alphabet knowledge and spelling. In study 1, a range of emergent literacy tasks was administered to 296 preschool children aged 4-5 years. The more advanced name writers outperformed the less advanced name writers on all emergent literacy measures. Furthermore, children with longer names did not show superior performance compared to children with shorter names. In study 2, four measures of alphabet knowledge and spelling were administered to 104 preschool children. Once again, the more advanced name writers outperformed the less advanced name writers on the alphabet knowledge and spelling measures. Results indicated that having longer names did not translate into an advantage on the alphabet knowledge and spelling tasks. Name writing proficiency, not length of name appears to be associated with preschool children's developing emergent literacy skills. Name writing reflects knowledge of some letters rather than a broader knowledge of letters that may be needed to support early spelling.     

Reversing letters and reading transformed text in dyslexia: A reassessment

The visual deficit hypothesis of development dyslexia has largely been abandoned because many of the phenomena that initially motivated it could not be replicated under controlled experimental conditions, while phonological processing deficits were found to provide a better explanation for the replicable phenomena. Nevertheless, many teachers and special educators continue to subscribe to the hypothesis that deficits of visual perception are a major cause of reading failure in dyslexia. As part of a larger family study, we reexamined the questions (1) whether probands and affected relatives in dyslexia families reverse easily confused letters more frequently under experimental conditions than normal readers from the same families, and (2) whether they show unusual facility in reading geometrically transformed text. The findings indicated that young dyslexia students reverse easily confused letters more often than normal readers. Reading group differences of letter reversal were significant in children from 7–10 years but not thereafter; and virtually no subject reversed letters when spelling whole words. Furthermore, dyslexic persons in every age group from 7–60 years actually took longer than normal readers to decode geometrically transformed text; and the time to decode transformed texts increased progressively with age after adolescence in both dyslexic persons and normal readers. Thus, reading group differences in decoding easily confused letters and reading geometrically transformed text do not support the visual deficit hypothesis and probably do not help to clarify the etiology of developmental dyslexia.     

Training phonemic segmentation ability with a phonemic discrimination intervention in second- and third-grade children with reading disabilities

The present study examined the possibility that phonemic discrimination training could improve the phonemic segmentation ability of children with reading disabilities. Half of the 32 children with reading disabilities (14 male and 4 female second graders and 10 male and 4 female third graders, with mean ages of 99.2 and 109.7 months, respectively) deficient in phonemic segmentation skills were assigned to the training group, while the other half acted as a nontrained control group. The trained children were successful at significantly improving their performance on the phonemic segmentation task. The control group made no improvement. Requiring children with reading disabilities to make discriminations concerning phonemic information may have helped them discover properties of the phoneme that they previously did not know.     

Frequency analyses of prephonological spellings as predictors of success in conventional spelling

The present study explored how children's prephonological writing foretells differential learning outcomes in primary school. The authors asked Portuguese-speaking preschool children in Brazil (mean age 4 year 3 months) to spell 12 words. Monte Carlo tests were used to identify the 31 children whose writing was not based on spellings or sounds of the target words. Two and a half years later, the children took a standardized spelling test. The more closely the digram (two-letter sequence) frequencies in the preschool task correlated with those in children's books, the better scores the children had in primary school, and the more preschoolers used letters from their own name, the lower their subsequent scores. Thus, preschoolers whose prephonological writing revealed attentiveness to the statistical properties of text subsequently performed better in conventional spelling. These analytic techniques may help in the early identification of children at risk for spelling difficulties.     

The role of invented spelling on learning to read in low-phoneme awareness kindergartners: a randomized-control-trial study

The goal of the present intervention research was to test whether guided invented spelling would facilitate entry into reading for at-risk kindergarten children. The 56 participating children had poor phoneme awareness, and as such, were at risk of having difficulty acquiring reading skills. Children were randomly assigned to one of three training conditions: invented spelling, phoneme segmentation, or storybook reading. All children participated in 16 small group sessions over 8 weeks. In addition, children in the three training conditions received letter-knowledge training and worked on the same 40 stimulus words that were created from an array of 14 letters. The findings were clear: on pretest, there were no differences between the three conditions on measures of early literacy and vocabulary, but, after training, invented spelling children learned to read more words than did the other children. As expected, the phoneme-segmentation and invented-spelling children were better on phoneme awareness than were the storybook-reading children. Most interesting, however, both the invented spelling and the phoneme-segmentation children performed similarly on phoneme awareness suggesting that the differential effect on learning to read was not due to phoneme awareness per se. As such, the findings support the view that invented spelling is an exploratory process that involves the integration of phoneme and orthographic representations. With guidance and developmentally appropriate feedback, invented spelling provides a milieu for children to explore the relation between oral language and written symbols that can facilitate their entry in reading.     

An investigation of four hypotheses concerning the order by which 4-year-old children learn the alphabet letters

This study tested four complementary hypotheses to characterize intrinsic and extrinsic influences on the order with which preschool children learn the names of individual alphabet letters. The hypotheses included: (a) own-name advantage, which states that children learn those letters earlier which occur in their own names, (b) the letter-order hypothesis, which states that letters occurring earlier in the alphabet string are learned before letters occurring later in the alphabet string, (c) the letter-name pronunciation effect, which states that children learn earlier those alphabet letters for which the name of the letter is in the letter's pronunciation, and (d) the consonant-order hypothesis, which states that children learn earlier those letters for which corresponding consonantal phonemes are learned early in phonological development. Participants were 339 four-year-old children attending public preschool classrooms serving primarily low-income children. Children's knowledge of each of the 26 alphabet letters was assessed, and these data were tested for the four hypotheses using a linear logistic test model (LLTM). Results from the LLTM confirmed all four hypotheses to show that the order of letter learning is not random, in that some letters hold an advantage over other letters to influence their order of learning. Implications for educational policy and practice are discussed.     

Knowledge of the alphabet and explicit awareness of phonemes in pre-readers: The nature of the relationship

This study was carried out to examine the extent to which preschool children are aware of the phonemic structure of the spoken word and to investigate how they acquire that knowledge. The four year old non-readers carried out a battery of takss designed to assess product name reading ability, knowledge of the alphabet, rhyme skills and explicit phonemic awareness ability. There was evidence that they generally acquired knowledge of the alphabet before they showed explicit phonemic awareness ability. Fixed order regression analyses showed that ability to read and write the alphabet generally accounted for unique variance in phoneme awareness and product name reading ability over and above that accounted for by rhyme skills but that rhyme ability accounted for no unique variance beyond that accounted for by alphabet knowledge. Further analyses showed that alphabet knowledge also contributed unique variance to product name reading ability over and above that accounted for by phonemic awareness ability but that the reverse was not the case. It was hypothesised that many preschool non-readers may start to gain an insight into the phonemic structure of the spoken word by becoming aware of the connection between the sounds of letters in environmental print and the sounds of the spoken word.     

RAN as a predictor of reading skills,and vice versa: results from a randomised reading intervention

Although phonemic awareness is a well-known factor predicting early reading development, there is also evidence that Rapid Automatized Naming (RAN) is an independent factor that contributes to early reading. The aim of this study is to examine phonemic awareness and RAN as predictors of reading speed, reading comprehension and spelling for children with reading difficulties. It also investigates a possible reciprocal relationship between RAN and reading skills, and the possibility of enhancing RAN by intervention. These issues are addressed by examining longitudinal data from a randomised reading intervention study carried out in Sweden for 9-year-old children with reading difficulties (N?=?112). The intervention comprised three main elements: training of phonics, reading comprehension strategies and reading speed. The analysis of the data was carried out using structural equation modelling. The results demonstrated that after controlling for autoregressive effects and non-verbal IQ, RAN predicts reading speed whereas phonemic awareness predicts reading comprehension and spelling. RAN was significantly enhanced by training and a reciprocal relationship between reading speed and RAN was found. These findings contribute to support the view that both phonemic awareness and RAN independently influence early phases of reading, and that both are possible to enhance by training.     

Visual processing of pictures and letters in alphabet books and the implications for letter learning

Alphabet books as studied in this research typically highlight one letter per page combined with a depiction of a word that begins with the letter (e.g., a bear illustrates B). This study tests whether children’s letter knowledge improves as a result of alphabet book sharing and how the visual processing of pictures and letters affects learning from repeated alphabet book readings. The study is designed as a randomized control trial in which participants were assigned to one of two experimental groups (N = 30) or a control group (N = 15). Half of the experimental group received version A in which the letters A–L were illustrated with anthropomorphic figures and the letters M–Z with objects. Half received version B in which the letters A–L were illustrated with objects and the letters M–Z with anthropomorphic figures. Mean age of the children was 57.6 months (SD = 3.6). While sharing the alphabet book we registered children’s eye movements in the first and fourth (last) reading session. Alphabet book reading stimulated letter knowledge although the make-up of the alphabet book moderated the effects. Relatively more visual attention to pictures of anthropomorphic figures interfered with learning letters from alphabet book sharing. Visual attention to letters also predicted letter knowledge and learning. Only a small part of each letter attracted children’s attention and the briefer their fixations on this distinctive area, the more letters they knew at the pretest and were able to learn from alphabet book sharing.     

Learning While Testing

Abstract

This study investigated the performance of preschool and kindergarten children with visual discrimination exercises drawn from reading readiness materials prior to visual discrimination training. The exercises contained three sources of stimuli: representations of objects, letters, and words. Results indicate that many preschoolers and most kindergartners measured possess the skills necessary to successfully perform visual discrimination exercises. The 8s were able to discriminate representations of objects and letters equally well; however, word stimuli were significantly harder to discriminate than either representations of objects or letters. Results indicate that visual discrimination training should be provided to pre-readers on a selected basis.     

Explicit Instruction in Decoding Benefits Children High in Phonemic Awareness and Alphabet Knowledge

This article reports a study of 32 children who had been trained to a high level in phonemic awareness and alphabet knowledge over a 12-week period at preschool. During their first 6 weeks in kindergarten, these phonemically aware children were taught to read 10 real words, using either decoding and encoding techniques or a whole word method. At posttesting the children taught by the decoding and encoding method were superior in reading and writing both novel real words and pseudowords, compared to the whole word group. The results support the contention that explicit instruction in decoding is helpful even when children have high levels of phonemic awareness.     

The impact of invented spelling on phonemic awareness

The objective of this study was to assess the impact of a training programme, designed to make preschool-age children's invented spelling evolve, on their phonemic awareness. The participants were 90 children who were divided into 3 experimental and 3 control groups based on the nature of their invented spelling. Children's phonemic skills were evaluated in a pre-test and a post-test. In between the experimental groups underwent the training program. The experimental groups achieved greater progress in the phonemic tests than the control groups. The training's impact on those tests differed depending on the level of the children's invented spelling.     

Computer-based learning of spelling skills in children with and without dyslexia

Our spelling training software recodes words into multisensory representations comprising visual and auditory codes. These codes represent information about letters and syllables of a word. An enhanced version, developed for this study, contains an additional phonological code and an improved word selection controller relying on a phoneme-based student model. We investigated the spelling behavior of children by means of learning curves based on log-file data of the previous and the enhanced software version. First, we compared the learning progress of children with dyslexia working either with the previous software (n = 28) or the adapted version (n = 37). Second, we investigated the spelling behavior of children with dyslexia (n = 37) and matched children without dyslexia (n = 25). To gain deeper insight into which factors are relevant for acquiring spelling skills, we analyzed the influence of cognitive abilities, such as attention functions and verbal memory skills, on the learning behavior. All investigations of the learning process are based on learning curve analyses of the collected log-file data. The results evidenced that those children with dyslexia benefit significantly from the additional phonological cue and the corresponding phoneme-based student model. Actually, children with dyslexia improve their spelling skills to the same extent as children without dyslexia and were able to memorize phoneme to grapheme correspondence when given the correct support and adequate training. In addition, children with low attention functions benefit from the structured learning environment. Generally, our data showed that memory sources are supportive cognitive functions for acquiring spelling skills and for using the information cues of a multi-modal learning environment.     

Alphabetic access route in beginning reading acquisition in Portuguese: The role of letter-name knowledge

The present study investigates Ehri's (Ehri & Wilce 1985; Scott & Ehri 1990) hypothesis that knowledge of the alphabet enables children to learn to read by processing and storing letter-sound relations in words. In particular, it examines whether letter-name knowledge facilitates the learning of spellings in which the names of one or more letters can be heard in the pronunciation of the words. Preschool children who could not read any word out of context were divided into two groups on the basis of their ability to name the letters of the alphabet: one group knew the names of the letters while the other did not. Both groups were taught to read two types of simplified spellings: visual spellings, that is, spellings whose letters did not correspond to sounds in the pronunciations of the words but which were visually more salient (e.g., X_QKO for the word cerveja), and phonetic spellings, that is, spellings whose letters corresponded to sounds in the pronunciation of the words (e.g., CRVA for the word cerveja). In all phonetic spellings, the name of at least one letter could be clearly heard in the pronunciation of the words. Results corroborated Ehri's hypothesis. The children who did not know the names of the letters learned to read the visual spellings more easily than the phonetic ones. On the other hand, the children who knew the names of the letters showed the opposite pattern, that is, they learned the phonetic spellings more easily than the visual ones.     

Contributions of Emergent Literacy Skills to Name Writing, Letter Writing, and Spelling in Preschool Children

The purpose of this study was to examine which emergent literacy skills contribute to preschool children's emergent writing (name-writing, letter-writing, and spelling) skills. Emergent reading and writing tasks were administered to 296 preschool children aged 4-5 years. Print knowledge and letter-writing skills made positive contributions to name writing; whereas alphabet knowledge, print knowledge, and name writing made positive contributions to letter writing. Both name-writing and letter-writing skills made significant contributions to the prediction of spelling after controlling for age, parental education, print knowledge, phonological awareness, and letter-name and letter-sound knowledge; however, only letter-writing abilities made a significant unique contribution to the prediction of spelling when both letter-writing and name-writing skills were considered together. Name writing reflects knowledge of some letters rather than a broader knowledge of letters that may be needed to support early spelling. Children's letter-writing skills may be a better indicator of children's emergent literacy and developing spelling skills than are their name-writing skills at the end of the preschool year. Spelling is a developmentally complex skill beginning in preschool and includes letter writing and blending skills, print knowledge, and letter-name and letter-sound knowledge.     

What type of computer-assisted exercise supports young less skilled spellers in resolving problems in open and closed syllable words?

Dutch bisyllabic words containing open and closed syllables are particularly difficult to spell for children. What kind of support in spelling exercises improves the spelling of these words the most? Two extensions of a commonly used dictation exercise were tested: less skilled spellers in grade 2 (n = 50; 7 years and 10 months) either received explicit syllabic segmentation cues or received spelling cues by means of a visual preview. Comparisons between pre-, post-, and retention tests of spelling skill showed that extra syllabic cues did not show a significant improvement beyond normal spelling dictation and that visual preview was most effective as compared to the other types of training. The findings suggest that word-specific knowledge can effectively be improved by exposure to the correct letter pattern during exercises in spelling and seems to result in lasting improvement of word-specific orthographic representations, at least for 5 weeks.     

The proper name as starting point for basic reading skills

Does alphabetic-phonetic writing start with the proper name and how does the name affect reading and writing skills? Sixty 4- to 5½-year-old children from middle SES families with Dutch as their first language wrote their proper name and named letters. For each child we created unique sets of words with and without the child’s first letter of the name to test spelling skills and phonemic sensitivity. Name writing correlated with children’s knowledge of the first letter of the name and phonemic sensitivity for the sound of the first letter of the name. Hierarchical regression analysis makes plausible that both knowledge of the first letter’s name and phonemic sensitivity for this letter explain why name writing results in phonetic spelling with the name letter. Practical implications of the findings are discussed.
