Cortical and Subcortical Mechanisms of Orthographic Word-form Learning.

We examined the initial stages of orthographic learning in real time as literate adults learned spellings for spoken pseudowords during fMRI scanning. Participants were required to learn and store orthographic word forms because the pseudoword spellings were not uniquely predictable from sound to letter mappings. With eight learning trials per word form, we observed changes in the brain's response as learning was taking place. Accuracy was evaluated during learning, immediately after scanning, and 1 week later. We found evidence of two distinct learning systems-hippocampal and neocortical-operating during orthographic learning, consistent with the predictions of dual systems theories of learning/memory such as the complementary learning systems framework [McClelland, J. L., McNaughton, B. L., & O'Reilly, R. C. Why there are complementary learning systems in the hippocampus and neocortex: Insights from the successes and failures of connectionist models of learning and memory. Psychological Review, 102, 419-457, 1995]. The bilateral hippocampus and the visual word form area (VWFA) showed significant BOLD response changes over learning, with the former exhibiting a rising pattern and the latter exhibiting a falling pattern. Moreover, greater BOLD signal increase in the hippocampus was associated with better postscan recall. In addition, we identified two distinct bilateral brain networks that mirrored the rising and falling patterns of the hippocampus and VWFA. Functional connectivity analysis revealed that regions within each network were internally synchronized. These novel findings highlight, for the first time, the relevance of multiple learning systems in orthographic learning and provide a paradigm that can be used to address critical gaps in our understanding of the neural bases of orthographic learning in general and orthographic word-form learning specifically.

Disentangling the Impact of Bilingualism and SES in Literacy Skills of Language-Minority Bilingual Children and Monolingual Peers Exposed to French

In the present study, we aimed to disentangle the impact of bilingualism and socioeconomic status (SES) on literacy in language-minority bilingual children (LMBC) and monolinguals exposed to French. We also wanted to explore the role of these two factors on cognitive and language skills, i.e., verbal knowledge (VK), morphosyntactic comprehension (MC), and phonological short-term memory (PSTM), well known to be important predictors of literacy acquisition. We compared LMBC with low and medium-high SES, and monolinguals with low and medium-high SES. All the children attended Grades 3, 4, and 5. We found that LMBC underperformed monolinguals on VK and MC. Low SES children showed lower scores compared to medium-high SES children on VK, MC, and PSTM. With regard to literacy, LMBC underperformed monolinguals on text and irregular word reading. Low SES children underperformed medium-high SES children only in regular word reading and pseudoword spelling. As a whole, bilingualism had an effect on measures involving lexical components, while SES had a more widespread effect on cognitive and language skills. The results are discussed considering implications for research, clinical, and educational settings.

Pseudoword spelling: insights into sublexical representations and lexical interactions

ABSTRACT In this work we introduce a new tool for measuring English spelling-sound consistency, the PG Toolkit, which we use to conduct detailed analyses of pseudoword spellings that provide new insights into the nature of sublexical and lexical representations. There are several key findings: first, sound-spelling consistency measured at two different “grain sizes”, phonographeme and onset/rime, each explained unique variance in pseudoword spelling. Second, lexical skill was more related to pseudoword accuracy at the onset/rime level than at the phonographeme level, and individuals who chose more consistent mappings to spell pseudowords tended to have better lexical skill. Finally, no unique contribution of consistency in the reading direction (“feedback”) was found after controlling for consistency in the spelling direction. Taken together, the results validate the various measures provided by the PG Toolkit and establish new evidence that supports an interpretation of sublexical processes as operations over hierarchically-structured representations.

Vocabulary Diversity in Personal Narratives Produced in Response to the Global TALES Protocol in Dutch-Speaking Students with and without Dyslexia

Introduction: This study examines whether there are differences in expressive vocabulary between participants with and without dyslexia in personal narratives in response to the Global TALES protocol. Methods: 22 monolingual Dutch-speaking participants aged 11–16 with dyslexia and 22 age and gender-matched peers without dyslexia were assessed on measures of decoding, reading comprehension, and spelling of words, pseudowords, verbs, and sentences. The participants also produced personal narratives in response to the six prompts contained in the Global TALES protocol. We analyzed the personal narratives for expressive vocabulary and counted the total number of different words (TNDW). Results: The study revealed a significant relationship between TNDW and reading comprehension (r = 0.45, p = 0.002, BF₁₀ = 17.70), spelling words (r = 0.42, p = 0.005, BF₁₀ = 8.93), and spelling and writing conventions in sentences (r = 0.37, p = 0.016, BF₁₀ = 3.11). The Global TALES protocol was successful in eliciting personal narratives in the Dutch-speaking participants with and without dyslexia. Participants with dyslexia used fewer different words (M = 192.27, SD = 64.37; 95% CI: [151.84–232.71]) compared to peers without dyslexia (M = 265.50, SD = 116.28; 95% CI: [225.06–305.93]; F(1, 42) = 6.68; p = 0.013; η² = 0.14). When we compared the probability of models, Bayesian factors revealed moderate evidence for group differences in TNDW (BF = 3.94). Conclusion: Our findings indicate that older school-age participants with dyslexia may lag behind their peers in expressive vocabulary in a personal narrative discourse task that is relevant to everyday functioning. The results of this study highlight the relationship between expressive vocabulary and reading comprehension and the importance of the assessment of spoken language skills in children with dyslexia. Reading problems might lead to less advanced spoken language, which in turn may negatively affect the expressive vocabulary growth in individuals with dyslexia.

Predictors of adult spelling in an orthography of intermediate depth

Abstract What is the hallmark of a good speller? Spelling is a critical component in learning to become literate, but how it works in literate adults remains poorly explored. We examined word and pseudoword spelling in 214 adults in relation to general cognitive abilities, vocabulary, reading history, reading performance, phonological processing and rapid automatized naming. We conducted hierarchical multiple regression analyses to uncover predictors of spelling performance and compared a subsample of good and poor spellers to identify patterns of cognitive and language abilities associated with high vs. low spelling ability. In the regression model under test, which progressed from general cognitive and language abilities to specific reading-related skills, the most important predictor for word spelling was vocabulary, and for pseudoword spelling phonological processing (phoneme deletion). The model explained 20% of word spelling, and 8% of pseudoword spelling, variance. Good spellers outperformed poor spellers in reading connected text and pseudowords, and in phonological processing; poor spellers typically had a history of reading difficulties but similar levels of cognitive ability, word reading and RAN performance. Overall, our findings indicate that adult spelling relies more strongly on word knowledge than on reading proficiency and that, as in literacy acquisition, good phonology-related abilities are a hallmark of proficient adult spellers.

Orthographic Knowledge and Clue Word Facilitated Spelling in Children With Developmental Language Disorder.

Purpose This study investigated the orthographic knowledge and how orthographic and phonological information could support children with developmental language disorder (DLD) to make more accurate spelling attempts. Method Children with DLD (N = 37) were matched with chronological age-matched (CAM) children and language age-matched children. These children completed specific and general orthographic knowledge tasks as well as spelling task conditions with either no clue word (pretest), a phonological clue word, or an orthographic clue word. Results Children with DLD were significantly less accurate in their specific orthographic knowledge, compared with CAM children, but had similar scores for general orthographic knowledge to CAM children. Children with DLD and both controls had significantly higher spelling scores in the orthographic clue word condition compared with a pretest pseudoword spelling task. Conclusions Children with DLD acquire the general knowledge of a written language's orthography but, possibly through less print exposure, have less well-represented word-specific orthographic knowledge. Moreover, children with DLD are able to extract the orthographic features of a clue word and employ these to produce more accurate spellings. These findings offer support for a spelling intervention approach based on orthography.

Orthographic Knowledge, and Reading and Spelling: A Longitudinal Study in an Intermediate Depth Orthography.

Orthographic knowledge is an important contributor to reading and spelling. However, empirical research is unclear about its long-lasting influence along with literacy development. We examined whether reading and spelling benefitted from an independent contribution of lexical and sublexical orthographic knowledge in European Portuguese, an intermediate depth orthography. This was investigated longitudinally from Grade 2 to 5 with two cohorts of Portuguese children, using common measures of orthographic knowledge, and word and pseudoword reading and spelling tasks. Regression analyses showed that lexical orthographic knowledge assessed at the beginning of Grade 2 predicted word reading at the beginning of Grade 3 (p < .05, variance explained = 6%), word spelling at the end of Grade 2 (p < .05, variance explained = 6%) and pseudoword spelling at the beginning of Grade 3 (p < .05, variance explained = 8%). They also revealed that lexical orthographic knowledge assessed at the beginning of Grade 4 predicted word spelling at the end of Grade 4 (p < .001, variance explained = 21%). Differently, sublexical orthographic knowledge evaluated at the beginning of Grade 2 and of Grade 4 only contributed to pseudoword spelling at the beginning of Grade 3 (p < .01, variance explained = 12%), and to pseudoword reading at the end of Grade 5 (p < .01, variance explained = 9%), respectively. Therefore, orthographic knowledge predicted spelling more often and earlier than reading. Furthermore, the results suggest that the influence of orthographic knowledge may vary during literacy development and, along with findings from other studies, that this influence at the lexical level may depend on orthographic consistency.

Pseudoword spelling ability predicts response to word spelling treatment in acquired dysgraphia

ABSTRACT Although rehabilitation of acquired dysgraphia can be quite effective, identifying predictors of responsiveness to treatment is useful for prognosis and individualization of treatment protocols. This study examined whether various features of treatment response were predicted by the integrity of one or more of the central cognitive components of spelling: orthographic long-term memory, orthographic working memory, and phoneme-grapheme conversion. Twenty dysgraphic individuals received 12 weeks of bi-weekly, individualized, lexically-based spelling rehabilitation using a spell-study-spell paradigm. Linear multiple regression modelling examined whether the type and severity of the dysgraphic deficit, assessed before rehabilitation, predicted the magnitude and rate of improvement, generalization to untrained items and maintenance of treatment gains. The results revealed that pseudoword spelling accuracy – indexing the integrity of the phoneme-grapheme conversion system – was the only factor examined that significantly predicted the rate of accuracy gains for trained words as well as the extent of generalization to untrained words. Pre-treatment pseudoword spelling accuracy also predicted retention of gains for trained and untrained words at 3-month follow-up. These findings reveal that the integrity of the phoneme-grapheme conversion system prior to dysgraphia rehabilitation may play a key role in rehabilitation-driven recovery, even when the treatment approach targets lexical rather than pseudoword spelling processes.

English Word and Pseudoword Spellings and Phonological Awareness: Detailed Comparisons From Three L1 Writing Systems.

Spelling is a fundamental literacy skill facilitating word recognition and thus higher-level reading abilities via its support for efficient text processing (Adams, 1990; Joshi et al., 2008; Perfetti and Stafura, 2014). However, relatively little work examines second language (L2) spelling in adults, and even less work examines learners from different first language (L1) writing systems. This is despite the fact that the influence of L1 writing system on L2 literacy skills is well documented (Hudson, 2007; Koda and Zehler, 2008; Grabe, 2009). To address this shortcoming, this study collected data on real word spelling, pseudoword spelling, and phonological awareness (elision) abilities from 70 participants (23 native speakers; 47 ELLs with alphabetic, abjad, and morphosyllabic L1s). Analyses compared performance on real word and pseudoword spelling between L1 English speakers and ELLs, and additionally among the non-native-speaker L1 groups (categorized into alphabet, abjad, and morphosyllabary groups). Similar comparisons were made across groups for performance on phonological awareness. Further, correlations were calculated between phonological awareness and real word spelling and between phonological awareness and pseudoword spelling, separately for L1 English speakers and the various ESL groups. Spelling accuracy on real words and pseudowords as well as phonological awareness skill differed between native speakers and ESL speakers, and also varied by the ESL speakers’ L1 writing system. Theoretically interesting patterns emerged in the spelling data. For example, the morphosyllabic L1 speakers had strong real word spelling (better than the other ESL groups) but greatly decreased pseudoword accuracy (a drop of 59% in accuracy). Although alphabetic L1 speakers had low spelling accuracy in terms of strict scoring, they had lower rates of errors per item, highlighting the importance of scoring approach for shaping the conclusions that are drawn. Error rates also revealed vowels to be more problematic than consonants, particularly in abjad L1 speakers. The results demonstrate that L2 spelling abilities, phonological awareness, and the relationships among them vary by L1 writing system, and that differing approaches to scoring and analysis may lead to varying conclusions.

‘I didn’t even know one of the conventions before’: Explicit EFL spelling instruction and individual differences

This study examined the impact of explicitly teaching orthographic conventions on the spelling of 92 Hebrew speaking strong versus struggling English as a foreign language (EFL) ninth grade students who had been studying English for three to four hours a week since third grade. Additionally, English spelling self-efficacy was examined and participants reflected on program impact. Experimental English real and pseudo-word spelling tests and spelling self-efficacy were administered. All students improved across lessons with stronger students reaching higher grades for each of the conventions. Results found both intervention groups improved for experimental real and pseudo-word spelling but not for standardized English spelling. Self-efficacy increased for all participants following the intervention program. Struggling EFL students reflected that the lessons had been beneficial. They would have preferred to have been taught more lessons, have longer lessons, have the conventions taught at a slower pace, and recommended teaching conventions from a younger age. Most of the strong students noted that the newly acquired knowledge generalized to their English vocabulary acquisition, their reading, writing, as well as their pronunciation.

Cognitive and language performance predicts effects of spelling intervention and tDCS in Primary Progressive Aphasia

Predictors of treatment effects allow individual tailoring of treatment characteristics, thereby saving resources and optimizing outcomes. Electrical stimulation coupled with language intervention has shown promising results in improving language performance in individuals with Primary Progressive Aphasia (PPA). The current study aimed to identify language and cognitive variables associated with response to therapy consisting of language intervention combined with transcranial direct current stimulation (tDCS). Forty individuals with PPA received written naming/spelling intervention combined with anodal tDCS or Sham, using a between-subjects, randomized design, with intervention delivered over a period of 3 weeks. Participants were assessed using a battery of neuropsychological tests before and after each phase. We measured letter accuracy during spelling of trained and untrained words, before, immediately after, 2 weeks, and 2 months after therapy. We used step-wise regression methods to identify variables amongst the neuropsychological measures and experimental factors that were significantly associated with therapy outcomes at each time-point. For trained words, improvement was related to pre-therapy scores, in RAVLT (5 trials sum), pseudoword spelling, object naming, digit span backward, spatial span backward and years post symptom onset. Regarding generalization to untrained words, improvement in spelling was associated with pseudoword spelling, RAVLT proactive interference, RAVLT immediate recall. Generalization effects were larger under tDCS compared to Sham at the 2-month post training measurement. We conclude that, for trained words, patients who improve the most are those who retain for longer language skills such as sublexical spelling processes (phoneme-to-grapheme correspondences) and word retrieval, and other cognitive functions such as executive functions and working memory, and those who have a better learning capacity. Generalization to untrained words occurs through improvement in knowledge of phoneme-to-grapheme correspondences. Furthermore, tDCS enhances the generalizability and duration of therapy effects.

Literacy development beyond early schooling: a 4-year follow-up study of Croatian

The purpose of this study was to investigate literacy development beyond the early school years. We investigated mean-level and rank-order changes in two reading (word decoding speed and reading comprehension) and two spelling (word and pseudoword spelling accuracy) tasks during a 4-year period from beginning to the later grades of elementary school, and examined whether rank-order changes in literacy skills could be predicted from verbal working memory, phonological awareness, and morpho-syntactic awareness. The sample consisted of Croatian speaking children, poor (n = 50) and good (n = 61) readers. Croatian is a language with a highly transparent orthography but a rather complex grammar. Word decoding speed and word spelling accuracy improved significantly over the study period, word decoding speed more so among good than among poor readers, supporting the Matthew effect hypothesis. Literacy skills were moderately stable, with the highest stability coefficients obtained for word decoding speed, and the lowest for pseudoword spelling. The predictors of rank-order changes varied across literacy outcomes, but did not differ for poor and good readers. Morpho-syntactic awareness predicted rank-order development of all outcomes except for word spelling. Phonological awareness predicted rank-order development of reading comprehension and word spelling. Verbal working memory predicted rank-order development of word spelling only, and at a low level. The finding that the more language related cognitive variables, i.e., morpho-syntactic and phonological skills, were stronger predictors of literacy development than working memory, for both poor and good readers, suggests remedial focus on these more predictive variables.

Spelling of Pseudowords and Real Words in Dutch-Speaking Children With and Without Dyslexia

The purpose of this study was to explore the spelling knowledge and skills of elementary school children with and without dyslexia who speak Dutch, a language with a relatively transparent orthography. Children in Grades 2–6 completed real and pseudoword spelling dictation tasks. Spelling performance was compared in 218 children with (n = 55) and without (n = 163) dyslexia. There was a medium effect size for morphological, phonological, combined, and etymological spelling skills for differences between students with and without dyslexia. In addition, spelling real words resulted in medium effect sizes, whereas spelling pseudowords resulted in small effect sizes. Children without dyslexia performed above the mean for the entire sample in Grade 4, whereas same-age peers with dyslexia did so 2 years later. Even so, Dutch-speaking children with dyslexia continued to have difficulty spelling words requiring phonological skills and spelling pseudowords even up to Grade 6. Clinicians are encouraged to be aware of the importance of the choice of spelling items in the assessment of dyslexia. The use of pseudowords appears to be helpful in older children to identify spelling problems.

The Role of Morphological and Phonological Awareness in the Early Development of Word Spelling and Reading in Typically Developing and Disabled Arabic Readers.

The study is a cross-sectional developmental investigation of morphological and phonological awareness in word spelling and reading in Arabic in reading-accuracy disabled (RD) children and in age-matched typically developing (TR) controls in grades 1-4 (N=160). Morphological awareness tasks targeted the root and word pattern derivational system of Arabic, in both the oral and the written modalities. Phonological awareness employed a variety of orally administered segmentation and deletion tasks. The results demonstrated early deficits in morphological awareness, besides deficits in phonological awareness, in RD children as compared with typically developing controls, as well as in word and pseudoword spelling and reading (voweled and unvoweled). While phonological awareness emerged as the strongest predictor of reading, morphological awareness was also found to predict unique variance in reading, and even more so in spelling, beyond phonological awareness and cognitive skills. The results demonstrate the early emergence of morphological awareness deficits, alongside phonological deficits in Arabic RD, as well as the role of morphological processing in early reading and spelling. These findings reflect the centrality of derivational morphology in the structure of the spoken and the written Arabic word. Copyright © 2017 John Wiley & Sons, Ltd.

Learning to spell in a language with transparent orthography: Distributional properties of orthography and whole-word lexical processing.

We examined how whole-word lexical information and knowledge of distributional properties of orthography interact in children's spelling. High- versus low-frequency words, which included inconsistently spelled segments occurring more or less frequently in the orthography, were used in two experiments: (a) word spelling; (b) lexical priming of pseudoword spelling. Participants were 1st-, 2nd-, and 4th-grade Italian children. Word spelling showed sensitivity to the distributional properties of orthography in all children: accuracy in spelling uncommon transcription segments emerged progressively as a function of word frequency and schooling. Lexical priming effects emerged as a function of age. When related primes contained an uncommon segment, 2nd- and 4th-graders preferred uncommon segments than common ones in spelling target pseudowords, thus inverting the response trend found in the control condition. A smaller but significant effect was present in 1st- graders, who, unlike 2nd- and 4th-graders, still preferred common segments, only slightly increasing the use of uncommon ones. A larger priming effect emerged for high-frequency primes than low-frequency ones. Results indicate that children learning to spell in a transparent orthography are sensitive to the distributional properties of the orthography. However, whole-word lexical representations are also used, with larger effects in more skilled pupils.

Comparing Bilingual to Monolingual Learners on English Spelling: A Meta-analytic Review.

This study reports on a meta-analysis to examine how bilingual learners compare with English monolingual learners on two English spelling outcomes: real-word spelling and pseudo-word spelling. Eighteen studies published in peer-reviewed journals between 1990 and 2014 were retrieved. The study-level variables and characteristics (e.g. sample size, study design and research instruments) were coded, and 29 independent effect sizes across the 18 retrieved studies were analysed. We found that bilinguals outperformed monolinguals on real-word spelling overall and more so in early grades, but monolinguals outperformed bilinguals on pseudo-word spelling. Further, bilinguals at risk for reading difficulties did better on real-word spelling than monolinguals at risk for reading difficulties. Having investigated systematic sources of variability in effect sizes, we conclude that in comparison with their monolingual peers, bilingual learners, especially those from alphabetic L1 backgrounds, are able to master constrained skills, such as English spelling, in the current instructional context.

NIVELES DE RESPUESTAS A UNA INTERVENCIÓN EN ORTOGRAFÍA

Este estudio se propuso analizar la respuesta de niños de 3er grado ante una intervención pedagógica destinada a promover la formación de representaciones ortográficas de palabras. Las palabras de entrenamiento contenían sílabas o morfemas ortográficamente complejos (con dos o más escrituras posibles). Luego de realizada la intervención se evaluó la escritura de las palabras de entrenamiento más un grupo de pseudopalabras no incluidas en la intervención pero que contenían las sílabas o morfemas incorporados a las palabras de entrenamiento. En base al desempeño en la escritura de palabras, se ubicó a los niños en grupos de alta o baja respuesta a la intervención. Se comparó a ambos grupos en la escritura de las pseudopalabras. Los resultados sugieren que los niños del grupo de alto nivel de respuesta tendieron a almacenar en mayor medida las unidades sub-léxicas presentes en las palabras de entrenamiento que el grupo de bajo nivel de respuesta.

Predicting Handwriting Difficulties Through Spelling Processes

This study examined whether spelling tasks contribute to the prediction of the handwriting status of children with poor and good handwriting skills in a cross-sectional study with 276 Spanish children from Grades 1 and 3. The main hypothesis was that the spelling tasks would predict the handwriting status of the children, although this influence would decrease with age due to a gradual automatization of handwriting skills. The results confirmed this hypothesis. Another interesting result was that the pattern of pseudoword and irregular word spellings as predictors of handwriting status changed from Grade 1 to Grade 3. In Grade 1, the pseudoword spelling task made a significant contribution, whereas the irregular word spelling task did not. The opposite pattern was found in Grade 3. These results may be a consequence of progressive acquisition of orthographic representations. The orthographic role of the task of writing the alphabet in order from memory in the prediction model was also analyzed. The writing of the alphabet in order from memory task made a significant contribution to the prediction of handwriting status of the children beyond the orthographic influence of spelling tasks. The additional effect of this task on the prediction of handwriting status is presumably due to the fact that this measure is based on fluency.
