Parallels between the reading and spelling deficits of two subgroups of developmental dyslexics

The spelling errors of third graders who fit phonological andsurface profiles of developmental dyslexia were analyzed, alongwith the errors of younger (reading level matched) andchronologically age matched non-dyslexic comparison groups. InStudy 1, errors were analyzed as phonologically constrained,unconstrained, or inaccurate and as either orthographicallyacceptable or unacceptable. Study 2 extended the errorclassification system to nonword spellings. The main finding wasthat different types of dyslexics produced different types oferrors. Both studies found that children produced spelling errorsconsistent with their type of dyslexia. The phonological groupshowed poor knowledge of phoneme-grapheme correspondences,consistent with the existence of a phonological deficit. Thesurface group's spelling error profile differed from thephonological group and closely resembled the younger normalcomparison group. This pattern is consistent with other evidencethat surface dyslexia represents a general delay in acquiringliteracy skills. The studies provide converging evidence, from aspelling task, that developmental dyslexia is a non-homogeneouscategory consisting of at least two major subtypes with distinctetiologies and behavioral sequelae.     

Spelling difficulties in Spanish-speaking children with dyslexia / Dificultades de escritura en niños españoles con dislexia

In addition to reading difficulties, a significant proportion of developmental dyslexics have spelling problems, which persist into adulthood. Studies carried out in languages with opaque orthographies have found that dyslexics frequently make phonological substitutions when spelling and have difficulties in developing orthographic representations of irregular words. Those errors seem to derive from an excessive use of phonological codes when writing. Minimal research in Spanish (relatively transparent orthography) about the relationship between dyslexia and spelling difficulties has been carried out to date. In this study, 19 Spanish-speaking developmental dyslexics (from 7 to 11 years old) and 28 controls (from 6 to 11 years old, distributed in two groups, one matched for age and the other for reading level with the dyslexics) performed a dictation task of 80 stimuli with different levels of orthographic consistency, in order to discover the codes they use in the writing process. Results showed that Spanish children with dyslexia made significantly more spelling errors, especially among the ruled and irregular words. These findings are consistent with the idea that these children have difficulties in developing orthographic representations and use phonological codes more frequently than non-dyslexics, resulting in phonologically plausible errors when writing irregular words. These results have important implications for the treatment of spelling difficulties in children with dyslexia, highlighting the need to focus on the correct acquisition of grapheme-phoneme conversion rules as well as the development of appropriate orthographic representations.     

Phonological spelling errors in the writing of dyslexic adolescents

Spelling researchers in the past have disagreed about the meaning of spelling errors for the diagnosis of dyslexia. Many studies have reported that spelling errors of individuals with dyslexia are similar to those of younger children but that they are not deviant or unusual. In this study, spelling errors from the spontaneous writing of 19 adolescents with a history of reading problems and persistent spelling difficulties were analyzed. The poorer spellers in this group made more errors than the better spellers on certain phonological and morphophonological constructions. Specifically, the poorer spellers made a disproportionately large number of errors in their representation of liquid and nasal consonants, especially after vowels, and their spellings of inflections -ed and -s. Even though poor spellers might eventually learn to spell with reasonable phonetic accuracy, their spelling appears to be marked by persistent, intractable difficulties representing specific phonological and morphophonological features of words.     

Morphology and spelling in French students with dyslexia: the case of silent final letters

Spelling is a challenge for individuals with dyslexia. Phoneme-to-grapheme correspondence rules are highly inconsistent in French, which make them very difficult to master, in particular for dyslexics. One recurrent manifestation of this inconsistency is the presence of silent letters at the end of words. Many of these silent letters perform a morphological function. The current study examined whether students with dyslexia (aged between 10 and 15 years) benefit from the morphological status of silent final letters when spelling. We compared, their ability to spell words with silent final letters that are either morphologically justified (e.g., tricot, “knit,” where the final “t” is pronounced in morphologically related words such as tricoter, “to knit” and tricoteur “knitter”) or not morphologically justified (e.g., effort, “effort”) to that of a group of younger children matched for reading and spelling level. Results indicated that the dyslexic students’ spelling of silent final letters was impaired in comparison to the control group. Interestingly, morphological status helped the dyslexics improve the accuracy of their choice of final letters, contrary to the control group. This finding provides new evidence of morphological processing in dyslexia during spelling.     

Do dyslexics misread a ROWS for a ROSE?

Insufficient knowledge of the subtle relations between words’ spellings and their phonology is widely held to be the primary limitation in developmental dyslexia. In the present study the influence of phonology on a semantic-based reading task was compared for groups of readers with and without dyslexia. As many studies have shown, skilled readers make phonology-based false-positive errors to homophones and pseudohomophones in the semantic categorization task. The basic finding was extended to children, teens, and adults with dyslexia from familial and clinically-referred samples. Dyslexics showed the same overall pattern of phonology errors and the results were consistent across dyslexia samples, across age groups, and across experimental conditions using word and nonword homophone foils. The dyslexic groups differed from chronological-age matched controls by having elevated false-positive homophone error rates overall, and weaker effects of baseword frequency. Children with dyslexia also made more false-positive errors to spelling control foils. These findings suggest that individuals with dyslexia make use of phonology when making semantic decisions both to word homophone and non-word pseudohomophone foils and that dyslexics lack adequate knowledge of actual word spellings, compared to chronological-age and reading-level matched control participants.     

Reading and spelling error analysis of native

This study was an investigation of reading and spelling errors of dyslexic Arabic readers (n=20) compared with two groups of normal readers: a young readers group, matched with the dyslexics by reading level (n=20) and an age-matched group (n=20). They were tested on reading and spelling of texts, isolated words and pseudowords. Two research questions were the focus of this study: What are the reading and spelling profile errors of dyslexic native Arabic speakers? What is the effect of the Arabic orthography on these types of errors? The results of the reading error analysis revealed a clear contribution of the uniqueness of the Arabic orthography to the types of errors made by the three different groups. In addition, the error profiles of the dyslexic readers were similar to the error profiles made by the younger reading-level-matched group in percentages and in quality. The most prominent types of errors were morphological and semiphonetic, which highlighted the contribution of the Arabic orthography to these types of errors. Consistently, the profile of the spelling errors was similar in percentages and quality among the dyslexics and the reading-level-matched group but different from the age-matched group on the spelling measures. The analysis of the spelling errors revealed that the dominant type of error was mostly phonetic due to the limited orthographic lexicon. In addition, the Arabic orthography also contributed to these types of errors because many spelling mistakes were made due to poor knowledge of the spelling rules. The results of the reading and spelling errors are discussed from a reading development point of view. Further, two models are suggested, one for reading and one for spelling, to illustrate the cognitive processes that underlie the reading and spelling mistakes in this type of orthography.     

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.     

What do spelling errors tell us? Classification and analysis of errors made by Greek schoolchildren with and without dyslexia

In this study we propose a classification system for spelling errors and determine the most common spelling difficulties of Greek children with and without dyslexia. Spelling skills of 542 children from the general population and 44 children with dyslexia, Grades 3–4 and 7, were assessed with a dictated common word list and age-appropriate passages. Spelling errors were classified into broad categories, including phonological (graphophonemic mappings), grammatical (inflectional suffixes), orthographic (word stems), stress assignment (diacritic), and punctuation. Errors were further classified into specific subcategories. Relative proportions for a total of 11,364 errors were derived by calculating the opportunities for each error type. Nondyslexic children of both age groups made primarily grammatical and stress errors, followed by orthographic errors. Phonological and punctuation errors were negligible. Most frequent specific errors were in derivational affixes, stress diacritics, inflectional suffixes, and vowel historical spellings. Older children made fewer errors, especially in inflectional suffixes. Dyslexic children differed from nondyslexic ones in making more errors of the same types, in comparable relative proportions. Spelling profiles of dyslexic children did not differ from those of same-age children with poor reading skills or of younger children matched in reading and phonological awareness. In conclusion, spelling errors of both dyslexic and nondyslexic children indicate persistent difficulty with internalizing regularities of the Greek orthographic lexicon, including derivational, inflectional, and word (stem) families. This difficulty is greater for children with dyslexia.

Spelling errors in adults with a form of familial dyslexia

We compared the spelling errors on the WRAT II made by adults (N = 24) with an apparent autosomal dominant form of dyslexia to those made by their normal adult relatives (N = 17) and by spelling-age matched normal controls (N = 17) using a computerized error evaluation program (SEEP). The normal adult relatives were significantly better than the dyslexics in both reading and spelling, but did not differ in age, education, or IQ. SEEP evaluated each error independently for both phonological and orthographic accuracy at 2 levels of complexity. Each level of complexity was analyzed separately using a 3 X 2 (group X dimension) analysis of variance. The main finding of interest was a significant group X dimension interaction effect at the complex level, which indicated that the dyslexics had a qualitatively different profile across the 2 dimensions than either normal group who had parallel profiles. The dyslexics performed like the younger normal group on the complex phonological dimension but like the adult normal group on the complex orthographic dimension. These results indicate a dissociation in this form of familial dyslexia between these 2 dimensions of spelling development, and suggest that these dyslexics may fit the subtype of dysphonetic or phonological dyslexia. The implications of these results for the underlying cognitive deficit in this form of dyslexia are discussed.     

Children with dyslexia are slow writers because they pause more often and not because they are slow at handwriting execution

It is commonly assumed that children with dyslexia are slower at handwriting than other children. However, evidence of slow handwriting in children with dyslexia is very mixed. Thirty-one children with dyslexia, aged 9 years, were compared to both age-matched children and younger spelling-ability matched children. Participants completed an alphabet-writing task and a composition task on the surface of a digital writing tablet. Children with dyslexia wrote the same amount of letters per minute in the alphabet task but wrote fewer words per minute when composing their texts than children of the same age. Crucially, no differences were found between children with dyslexia and their same age peers for speed of handwriting execution, measured by the tablet, when writing the alphabet or composing their texts. However, children with dyslexia were found to pause within their compositions as often as the spelling ability matched group. Thus handwriting execution is not impaired in children with dyslexia. The slow writing that is typical of children with dyslexia is due to pausing more often when composing and is related to spelling ability. This may reflect processing problems in response to high cognitive load through having to contend with spelling and composing concurrently.     

Foregrounded Beauty: A Brief Analysis of Cummings’ Typical Poems from the Perspective of Stylistics

E. E. Cummings is one of the representatives of American modern experimental poets whose poems are well-known for the unique style. Cummings endeavors to make his poems be different from other poets’. He broke the traditional way of writing poems, invented in the changing of lines of the poem and the spelling of the words in the poem, thus to make his personal poem style distinctive. Therefore, standing on the stylistic point of view, this paper makes a brief analysis on Cummings’ typical poems from foregrounding perspective.     

Effectiveness of computer-based treatment for dyslexia in a clinical care setting: outcomes and moderators

The clinical effectiveness of a treatment for children with dyslexia was examined, as well as the moderating impact of plausible cognitive and socio-economic factors on treatment success. Results revealed that the treatment group accrued significant greater gains than the control group in reading and spelling skills. The treatment group obtained a level of reading accuracy and spelling that was comparable with the normative mean. Post-treatment levels of reading rate were comparable to the lower bound of the normal range. Treatment effectiveness was robust against individual differences, except for a moderating impact of phonological memory and rapid automatized naming.     

Phonological skill,lexical decision and letter report performance in good and poor adult spellers

Two groups of undergraduate students, matched for reading skill but differing in spelling ability, participated in three experiments with the aim of exploring the causes of differences in spelling skill in this population. In the first experiment participants were presented with a range of tasks to investigate the possibility that the poor spellers had poorer phonological abilities than the good spellers. No significant differences were observed. In Experiment 2, a lexical decision task was used. The words in the task differed in orthographic neighbourhood size (N) and frequency. Analysis of the latencies revealed effects of frequency and N, but the effect of spelling group was not significant and neither was the interaction with N. Analysis of the errors revealed that the poor spellers made significantly more errors than the good spellers. In Experiment 3 participants were asked to identify the letters in briefly presented words and non‐words. There was a significant effect of stimulus type in favour of words. Poor spellers made more errors in the task than the good spellers, although the difference was restricted to non‐words. Finally, an analysis of the errors made in spelling to dictation by the two groups was carried out. This revealed that the poor spellers were more likely than the good spellers to make errors that were not phonologically plausible and that differed markedly from the target. Overall, the results are interpreted in terms of a partial orthographic representations explanation of poor spelling in good readers.     

Spelling of Deaf Children Who Use Cochlear Implants

The spellings of 39 profoundly deaf users of cochlear implants, aged 6 to 12 years, were compared with those of 39 hearing peers. When controlled for age and reading ability, the error rates of the 2 groups were not significantly different. Both groups evinced phonological spelling strategies, performing better on words with more typical sound–spelling correspondences and often making misspellings that were phonologically plausible. However, the magnitude of these phonological effects was smaller for the deaf children than for hearing children of comparable reading and spelling ability. Deaf children with cochlear implants made the same low proportion of transposition errors as hearing children. The findings indicate that deaf children do not rely primarily on visual memorization strategies, as suggested by previous studies. However, deaf children with cochlear implants use phonological spelling strategies to a lesser degree than hearing peers.     

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.     

Adolescent Weak Decoders Writing in a Shallow Orthography: Process and Product

It has been hypothesized that students with dyslexia struggle with writing because of a word-level focus that reduces attention to higher level textual features (structure, theme development). This may result from difficulties with spelling and/or difficulties with reading. Twenty-six Norwegian upper secondary students (M = 16.9 years) with weak decoding skills and 26 age-matched controls composed expository texts by keyboard under two conditions: normally and with letters masked to prevent them reading what they were writing. Weak decoders made more spelling errors and produced poorer quality text. Their inter-key-press latencies were substantially longer preword, at word end, and within word. These findings provide some support for the word-level focus hypothesis, although we found that weak decoders were slightly less likely to engage in word-level editing. Preventing reading did not affect differences between weak decoders and controls, indicating that their reduced fluency was associated with production rather than reading difficulties.

Spelling in Children With Dyslexia: Analyses From the Treiman-Bourassa Early Spelling Test

We examined the oral and written spelling performance on the Treiman-Bourassa Early Spelling Test (Treiman & Bourassa, 2000a) of 30 children with serious reading and spelling problems and 30 spelling-level-matched younger children who were progressing normally in learning to read and spell. The 2 groups' spellings were equivalent on a composite measure of phonological and orthographic sophistication, representation of the phonological skeleton of the items, and orthographic legality. The groups showed a similar advantage for words over nonwords on the phonological skeleton and orthographic legality measures. The children with dyslexia and the comparison children also showed an equivalent advantage for written over oral spelling on the composite and phonological skeleton measures. Further analyses revealed that children with dyslexia made many of the same linguistically based errors as typically developing children but also pointed to some subtle differences between the groups. Overall, the spelling performance of children with dyslexia appears to be quite similar to that of normally progressing younger children.
