Environmental factors contributing to using spelling in communication: Perceptions of literate aided communicators.

The aim of this interpretive qualitative study was to explore how environmental factors influence the transition from relying solely on graphic symbols to using spelling in face-to-face communicative interactions, from the perspective of literate adults with speech and motor impairments who use augmentative and alternative communication (AAC). Fourteen adults either chose to submit a written story with weekly email follow-up, took part in interviews conducted via Zoom1, or chose to communicate solely by email. Researchers analyzed data using Charmaz's (2014) constructivist grounded theory approach. The analysis yielded three themes explaining environmental factors relevant to the transition from using graphic symbols to spelling in communication: (a) access to AAC systems and services; (b) knowledgeable and supportive communication partners who have high expectations; and (c) opportunities to learn reading, writing, and spelling. Supportive factors included providing sufficient time for spelling in communicative interactions, structured learning opportunities for practice and independence, opportunities to learn through socially meaningful interactions and having print-rich and language-rich activity settings. Slow speed in navigating graphic symbols and lack of ability to express an exact message were motivational reasons for participants to use spelling in communicative interactions. The interaction among environmental factors and person-related characteristics warrants further investigation.

Spelling development of children with and without reading difficulties throughout elementary grades: evidence from the Greek orthography.

The purpose of this longitudinal study was to examine the development of spelling in a large sample (N = 503, boys: N = 219) of Greek-speaking children with (N = 41) and without (N = 462) reading difficulties. Children were initially tested in Grades 2-4 and then at five consecutive measurement points over a 3-year period, focusing on how initial reading ability, grade, and gender may moderate the rate of spelling growth. Individual growth curve modeling revealed continuous growth of spelling performance in the total sample, although the growth rate decreased over time for children first tested in Grades 3-4. Spelling growth rate was also significantly slower among children with reading difficulties between Grades 2-4 and 3-5. The two reading groups displayed similar growth rates between Grades 4 and 6. Spelling growth rates did not vary significantly with gender. Overall, our study highlights the persistence of spelling difficulties even after 6 years of systematic teaching in children with reading difficulties. The severe and persistent spelling deficits of Greek-speaking children with reading difficulties may be attributed to the rich morphological system of the Greek language, the intermediate Greek orthographic transparency (in the direction of writing), and their limited experience with print.

From spelling to reading: An intervention program with children at risk of reading failure.

This study aimed to assess the impact of an interactive spelling program on reading acquisition of children at risk of developing reading difficulties as well as to assess its effect on spelling and phonemic awareness. From an initial pool of 144 first-grade children attending four Portuguese primary schools, 53 children with low performances in letter knowledge and phonemic awareness tasks, and considered by their teachers to be at risk of developing reading difficulties, were selected. These children were randomly assigned to three groups: an experimental group that underwent an interactive spelling program, a comparison group that underwent a phonological awareness program, and a control group that underwent a copying program. The programs, conducted in pairs, comprised 12 sessions lasting 20 to 30 min twice a week. The pretest and posttest included word reading, word spelling, and phonemic awareness assessments. Data analysis showed that the spelling group significantly outperformed the other groups across all measures except in the phonemic awareness task, where there were no differences with the phonological group. The word copying group consistently yielded the lowest results. Unlike the other two groups, the posttest results of the experimental group also reached the class average in word reading. For ethical reasons, after the final assessments the control group underwent a version of the interactive spelling program. This study suggests that spelling activities can contribute significantly to reading acquisition and can serve as a valuable pedagogical tool to proactively address challenges in learning to read.

Spelling principles matter: An ERP study investigating the processing of different types of pseudohomophones.

Spelling in any writing system is governed by fundamental principles. We examined the processing of two types of pseudohomophones constructed from words whose spellings are based on different principles - on the traditional principle of writing, requiring memorization of their spelling, and on the morphological principle, allowing the determination of their spelling from another word with the same morpheme (root) to examine the dependence of the occurrence of orthography-phonology conflict on spelling principles. Event-related potentials were recorded from 22 volunteers during silent reading. Pseudohomophones based on the morphological principle increased the N400 amplitude, emphasizing semantic and morphological processing importance. The P600 component showed significant effects for differentiating words and pseudohomophones based on the traditional principle, predominantly indicating the involvement of memory and reanalysis processes. Source reconstruction demonstrates that both pseudohomophones activate the left inferior frontal gyrus. However, pseudohomophones based on the traditional principle additionally activate the right and left postcentral gyrus, indicating the involvement of additional areas in the differentiation process. The earlier differences for stimuli based on the morphological principle indicate access to smaller units (morphemes), whereas stimuli based on the traditional principle require whole word processing. Our findings underscore the significant role of spelling principles in orthographic processing.

Which skills underlie French-speaking children's lexical spelling acquisition in elementary school? Insight from a cross-sectional exploratory network study from Grade 1 to Grade 5.

Learning to spell in an inconsistent orthographic system is a true challenge for primary school children. Previous empirical studies have highlighted three main skills involved in this learning process: phonological skills, morphological skills, and children's sensitivity to graphotactic regularities. However, the literature shows contradictions in the exact nature of the contribution of each skill at different stages of the learning process. So, the aim of our study was to test the contribution of this set of skills in the acquisition of lexical spelling as a function of children's grade level. For this purpose, we assessed these dimensions in a cross-sectional sample of 1101 French-speaking children from Grade 1 to Grade 5. The analyses were conducted using data-driven exploratory network modeling. The results showed (a) a predominant role of phonological skills at the beginning of learning, which tends to decrease with advancing schooling; (b) an increasing contribution of morphological skills from Grade 1 to Grade 5 with a drop in Grade 4, which is the only contribution that continues to increase in Grade 5; and (c) a contribution of the sensitivity to graphotactic regularities that tends to be stable until Grade 4 before decreasing in Grade 5. Our findings show the importance of all three skills in a dynamic process in learning to spell. The implications of these results are discussed in light of the integration of multiple patterns model of learning to spell.

A comparison of two user-friendly methods to identify and support correction of misspelled medications.

Objective: To identify and support correction of misspelled medication names recorded as free text, we compared the relative effectiveness of two user-friendly methods, used without reliance on clinical knowledge. Methods: Leveraging the SAS® COMPGED function, fuzzy string search programs examined 1.8 million medication records from 183,600 World Trade Center General Responder Cohort monitoring visits conducted in New York and New Jersey between 7/16/2002 and 3/31/2021, producing replicable generalized edit distance scores between the reported and correct spelling. Scores < 120 were selected as optimal and compared to Stedman's 2020 Plus Medical/Pharmaceutical Spell Checker first suggested word, used as the comparative standard because it employs both spelling and phonetic similarities to suggest matching words. We coded each methods' results as identifying or not identifying the medications within each visit. Results: Most types of medications (94.4 % anxiety, 98.4 % asthma and 94.6 % ulcer/gastroesophageal reflux disease) were correctly spelled. Cross tabulations assessed the agreement (anxiety 99.9 %, asthma 99.6 % and 98.4 % ulcer/ gastroesophageal reflux disease), false positive (respectively 0.02 %, 0.03 % and 2.0 %) and false negative (respectively 1.9 %, 0.5 % and 1.0 %) values. Scores < 120 occasionally correctly identified medications missed by the spell checker. We observed no difference in medication misspellings across socio-economically and culturally diverse patient characteristics. Conclusions: Both methods efficiently identified most misspelled medications, greatly minimizing the review and rectification needed. The fuzzy method is more universally applicable for condition-specific medications identification, but requires more programming skills. The spell checker is inexpensive, but benefits from modest programming skills and is only available in some languages.

The English Sublexical Toolkit: Methods for indexing sound-spelling consistency.

This work introduces the English Sublexical Toolkit, a suite of tools that utilizes an experience-dependent learning framework of sublexical knowledge to extract regularities from the English lexicon. The Toolkit quantifies the empirical regularity of sublexical units in both the reading and spelling directions (i.e., grapheme-to-phoneme and phoneme-to-grapheme) and at multiple grain sizes (i.e., phoneme/grapheme and onset/rime unit size). It can extract multiple experience-dependent regularity indices for words or pseudowords, including both frequency indices (e.g., grapheme frequency) and conditional probability indices (e.g., grapheme-to-phoneme probability). These tools provide (1) superior estimates of the regularities that better reflect the complexity of the sublexical system relative to previously published indices and (2) completely novel indices of sublexical units such as phonographeme frequency (i.e., combined units of individual phonemes and graphemes that are independent of processing direction). We demonstrate that measures from the toolkit explain significant amounts of variance in empirical data (naming of real words and lexical decision), and either outperform or are comparable to the best available consistency measures. The flexibility of the toolkit is further demonstrated by its ability to readily index the probability of different pseudowords pronunciations, and we report that the measures account for the majority of variance in these empirically observed probabilities. Overall, this work provides a framework and resources that can be flexibly used to identify optimal corpus-based consistency measures that help explain reading/spelling behaviors for real and pseudowords.

Preschool emergent literacy skills as predictors of reading and spelling in Grade 2 and the role of migration background in Germany.

Children's emergent literacy skills are essential for the development of later literacy abilities and school success. However, children with migration background often show poorer language skills in the majority language and are at a greater risk of developing literacy deficits. In addition, there is evidence for the predictive role of emergent literacy skills in reading comprehension, but there has been relatively little research concerning the association between preschool emergent literacy skills and word reading and spelling in Germany, especially for children with migration background. This study examines the associations of emergent literacy skills (vocabulary, phonological awareness [PA], letter knowledge, and rapid naming) with word reading and spelling from kindergarten to the end of Grade 2 and evaluates the role of migration background (i.e., use of the majority or minority language at home) in these associations. Data from 187 preschool children were obtained before school entry (Mage = 63.58 months, SD = 4.45). The results show that vocabulary and letter knowledge were strong predictors of word reading, whereas letter knowledge and PA were significant predictors of spelling. Furthermore, children's migration background was negatively associated with preschool vocabulary and PA. For children with migration background, vocabulary was a significant predictor of word reading, whereas letter knowledge was the best predictor of word reading for children without migration background. The results reflect the complexity of language development and the relevance of emergent literacy skills as predictors for word reading and spelling. Specific interventions should be developed to promote children's literacy abilities.

Oral language predictors of word reading and spelling: A cross-linguistic comparison in bilingual and monolingual children.

The current study investigated linguistic predictors of word reading and spelling skills in a cross-linguistic comparison (French vs. Italian) in heritage bilinguals (HBs) and their monolingual peers. The sample included 265 children (French: n = 113; 67 monolinguals and 46 HBs; Italian: n = 152; 82 monolinguals and 70 HBs) attending Grades 3, 4, and 5 while performing oral language, reading, and spelling tasks. The battery included verbal knowledge, morphosyntactic comprehension, nonword repetition, word reading (speed and accuracy), and spelling tasks. Results showed that for reading speed, there were no main effects of single predictors, but a significant interaction of morphosyntactic comprehension by language of schooling emerged. For reading accuracy, there was a main effect of verbal knowledge and syntactic comprehension, with a significant interaction of verbal knowledge and language of schooling. Finally, spelling accuracy was predicted only by linguistic status. The results suggest different pathways for word reading and spelling, with oral language skills' main role in reading accuracy and linguistic status's main role in spelling skills, possibly hindered by linguistic exposure and lexical access. Discussions are focused on potential implications for multilingual settings and cross-linguistic research.

White matter associations with spelling performance.

Multiple neurocognitive processes are involved in the highly complex task of producing written words. Yet, little is known about the neural pathways that support spelling in healthy adults. We assessed the associations between performance on a difficult spelling-to-dictation task and microstructural properties of language-related white matter pathways, in a sample of 73 native English-speaking neurotypical adults. Participants completed a diffusion magnetic resonance imaging scan and a cognitive assessment battery. Using constrained spherical deconvolution modeling and probabilistic tractography, we reconstructed dorsal and ventral white matter tracts of interest, bilaterally, in individual participants. Spelling associations were found in both dorsal and ventral stream pathways. In high-performing spellers, spelling scores significantly correlated with fractional anisotropy (FA) within the left inferior longitudinal fasciculus, a ventral stream pathway. In low-performing spellers, spelling scores significantly correlated with FA within the third branch of the right superior longitudinal fasciculus, a dorsal pathway. An automated analysis of spelling errors revealed that high- and low- performing spellers also differed in their error patterns, diverging primarily in terms of the orthographic distance between their errors and the correct spelling, compared to the phonological plausibility of their spelling responses. The results demonstrate the complexity of the neurocognitive architecture of spelling. The distinct white matter associations and error patterns detected in low- and high- performing spellers suggest that they rely on different cognitive processes, such that high-performing spellers rely more on lexical-orthographic representations, while low-performing spellers rely more on phoneme-to-grapheme conversion.

Modeling Item-Level Spelling Variance in Adults: Providing Further Insights into Lexical Quality.

Purpose: The lexical quality (LQ) hypothesis predicts that a skilled reader's lexicon will be inhabited by a range of low- to high-quality items, and the probability of representing a word with high quality varies as a function of person-level, word-level, and item-specific variables. These predictions were tested with spelling accuracy as a gauge of LQ. Method: Item-response based crossed random effects models explored simultaneous contributions of person-level (e.g., participant's decoding skill), word-level (e.g., word's transparency rating), item-specific (e.g., participant's familiarity with specific word), and person-by-word interaction predictors (e.g., decoding by transparency rating interaction) to the spelling of 25 commonly misspelled irregular English words in 61 undergraduate university students (M = 19.4 years, 70.49% female, 39.34% Hispanic, 81.97% White). Results: Substantial variance among individuals in item-level spelling accuracy was accounted for by person-level decoding skill; item-specific familiarity, proportion of schwas correctly represented, and correctly identifying the word from its mispronunciation; and an interaction of transparency rating by general decoding skill. Conclusions: Consistent with the LQ hypothesis, results suggest that one's ability to form a high-quality lexical representation of a given word depends on a complex combination of person-level abilities, word-level characteristics, item-specific experiences, and an interaction between person- and word-level influences.

Computer-Assisted or Instructor-Led Reading Instructions of Portuguese Words with Orthography Difficulties

This article presents the findings of a study comparing a computer-assisted teaching program to traditional instructor-led teaching for elementary school children. The study evaluated reading and writing skills and employed a group design. Results showed that both teaching approaches were effective in improving reading performance, with slightly better gains in the instructor-led version. Both conditions facilitated learning transfer to new words with spelling difficulties, although the computer-assisted condition demonstrated higher generalization in final tests. Motivational and attentional factors, easily addressed by instructors but challenging in computer programs, were highlighted. The instructor-led condition's personalized feedback and differential consequences potentially contributed to the observed differences in learning gains. Individual differences in learners' input and performance were emphasized, suggesting the need for program adaptations. The advantages of computer-assisted teaching, such as scalability and individualized pacing, were discussed, along with the need for further refinements and automation. Strategies for enhancing teaching sequence flexibility and reducing the instructor's decision-making burden were proposed. The study contributes valuable insights into computer-assisted reading instructions for children with spelling difficulties, emphasizing their benefits and areas for improvement. The research underscores the importance of designing effective technology-mediated interventions and provides guidance for future developments in this field. (AU)

The challenge of remote treatment in neuropsychological intervention for reading and spelling in dyslexia: A prospective observational cohort study.

Telemedicine approaches have proved to be valuable solutions for the delivery of treatment for many health-related issues, and crucial during the pandemics. Nonetheless, the efficacy of such Web-based practices in developmental dyslexia needs to be thoroughly evaluated. To this aim, the effects of a multi-componential program for neuropsychological intervention in dyslexia delivered as an outpatient program were compared with those obtained with a remotely delivered, Web-based treatment, based on the same methodological principles and delivered with the same duration and intensity. The treatment-related changes obtained with a combination of visual hemisphere-specific stimulation and training of visual-spatial attention through action video games, were compared to those obtained through remote treatment via the Tachidino Web-based platform. Both treatments had a duration of 4 weeks. The same battery of reading and phonemic awareness tests was delivered in presence, before and after treatment, as well as at 6-months follow-up. User satisfaction was assessed through parents and user questionnaires. Both treatments were significantly and similarly effective in improving reading speed, reading accuracy, and writing accuracy. No reduction in the effects was observed after treatment discontinuation. The Web-based treatment may thus offer a valid alternative to in-person intervention, optimizing the flexibility, capillary diffusion and cost-effectiveness of intervention.

A systematic review on the use of technology to enhance the academic achievements of children with attention deficit hyperactivity disorder in language learning.

This review investigates the use of technology for children and adolescents with Attention Deficit Hyperactivity Disorder and their academic achievements in language learning, as well as their attitudes towards technology use. The goal is to integrate this information in order to learn how technology is provided to this population regarding first and second language learning, and also how effective and appropriate its use is and how it is perceived by stakeholders in the learning process. A systematic review was conducted, and after the final screening process, 15 studies were analysed, the majority of which were about first language learning (n = 11). Most studies found that technology use has a positive impact on students' language skills and that students tend to find it more motivating and engaging. While these technologies seem to be promising tools for improving skills, further studies must be conducted, especially in the field of second language learning.

Orthography-phonology consistency in English: Theory- and data-driven measures and their impact on auditory vs. visual word recognition.

Research on orthographic consistency in English words has selectively identified different sub-syllabic units in isolation (grapheme, onset, vowel, coda, rime), yet there is no comprehensive assessment of how these measures affect word identification when taken together. To study which aspects of consistency are more psychologically relevant, we investigated their independent and composite effects on human reading behavior using large-scale databases. Study 1 found effects on adults' naming responses of both feedforward consistency (orthography to phonology) and feedback consistency (phonology to orthography). Study 2 found feedback but no feedforward consistency effects on visual and auditory lexical decision tasks, with the best predictor being a composite measure of consistency across grapheme, rime, OVC, and word-initial letter-phoneme. In Study 3, we explicitly modeled the reading process with forward and backward flow in a bidirectionally connected neural network. The model captured latent dimensions of quasi-regular mapping that explain additional variance in human reading and spelling behavior, compared to the established measures. Together, the results suggest interactive activation between phonological and orthographic word representations. They also validate the role of computational analyses of language to better understand how print maps to sound, and what properties of natural language affect reading complexity.

Phonological Awareness and Rapid Automatized Naming: The Mediating Effect of Word Reading and Spelling in Children with Developmental Dyslexia, Attention Deficit Hyperactivity Disorder, and Mild Intellectual Disability.

INTRODUCTION: In learning to read, children learn to integrate orthographic, phonological, and semantic codes into highly specified and redundant lexical representations. The aim is to test a proposed model for the relationship between phonological awareness (PA) and rapid automatized naming (RAN) as mediated by word reading (WR) and spelling (SP) in children with developmental dyslexia (DD), attention deficit hyperactivity disorder (ADHD), and mild intellectual disability (ID). METHODS: The relation between PA and RAN was found to be mediated by WR and SP in children with DD, ADHD, and mild ID. Three groups of children were included: DD children (N = 70), ADHD children (N = 68), and ID children (N = 69). This is a quantitative correlational, cross-sectional study investigating the strength and direction of relationships among proposed variables. RESULTS: The relation between PA and RAN was found to be mediated by WR and SP. Based on their correlation analysis, the researcher concluded that there are significant correlations between PA, RAN, WR, and SP. PA correlates positively with RAN and SP. RAN correlates positively with WR and SP. CONCLUSION: The study extended our knowledge of the relationship between PA and RAN as mediated by WR and SP in children with DD, ADHD, and mild ID. In practice, this is conducive to promote the utilization of "PA" and "RAN" so as to improve the early literacy skills (WR and SP) among children with DD, ADHD, and mild ID.

Spelling monosyllabic English words.

We conducted a megastudy to examine the spelling of American English monosyllables with typewritten responses. We related both sublexical and lexical/semantic factors to spelling accuracy and reaction time (RT) for the first keypress and response duration for spelling 1,856 monophonic monosyllables. We found that (a) each of 13 predictor variables was significantly related to performance for at least one measure, (b) orthographic length was unrelated to the first key RT, but did relate to accuracy and response duration, (c) sound-spelling and spelling-sound consistency was related to performance, and in particular, onset consistency related to accuracy and first key RT, but was unrelated to response duration, (d) contextual diversity was consistently related to performance across all measures, and (e) age of acquisition (AoA) was related to all measures, but was related more to the first key RT than response duration. The results indicate that people begin the spelling process once they identify the first letter, and they continue to process the spelling pattern as the response unfolds. These results are best explained by a parallel-distributed-processing framework.

Do letters matter? The influence of spelling on acoustic duration.

The present article describes a modified and extended replication of a corpus study by Brewer (2008. Phonetic reflexes of orthographic characteristics in lexical representation. Tucson, AZ: University of Arizona PhD thesis) which reports differences in the acoustic duration of homophonous but heterographic sounds. The original findings point to a quantity effect of spelling on acoustic duration, i.e., the more letters are used to spell a sound, the longer the sound's duration. Such a finding would have extensive theoretical implications and necessitate more research on how exactly spelling would come to influence speech production. However, the effects found by Brewer (2008) did not consistently reach statistical significance and the analysis did not include many of the covariates which are known by now to influence segment duration, rendering the robustness of the results at least questionable. Employing a more nuanced operationalization of graphemic units and a more advanced statistical analysis, the current replication fails to find the reported effect of letter quantity. Instead, we find an effect of graphemic complexity. Speakers realize consonants that do not have a visible graphemic correlate with shorter durations: the /s/ in tux is shorter that the /s/ in fuss. The effect presumably resembles orthographic visibility effects found in perception. In addition, our results highlight the need for a more rigorous approach to replicability in linguistics.

Are children with early literacy difficulties at risk for anxiety disorders in late childhood?

The present study examined whether literacy difficulties in both grades 2 and 3 are associated with social and generalized anxiety within the school environment in grade 5 and if children with different literacy difficulties differ in anxiety levels compared to typically developing children in grade 5 after controlling for inattention. Sixty-nine Greek children with literacy difficulties and fifty-two children with typical literacy development were assessed at the beginning of grade 2 and at the end of grade 3 on standardized literacy measures (reading accuracy, text-reading fluency, reading comprehension, and spelling). In grade 5, teachers were asked to rate their children's social and generalized anxiety levels and inattentive behavior in the school context. Results of one-way ANCOVAs showed that children with literacy difficulties were experiencing more social anxiety than typically developing children. Furthermore, children with both reading and spelling difficulties, but not those with single reading or spelling difficulties, had more social anxiety. These findings suggest that there is a close connection between early literacy difficulties and social anxiety in upper elementary grades and particularly among children with both reading and spelling difficulties. Implications for both teachers and other professionals who support children's socioemotional development will be discussed.

Written language preservation in glioma patients undergoing awake surgery: The value of tailored intra-operative assessment.

Written language is increasingly important, as contemporary society strongly relies on text-based communication. Nonetheless, in neurosurgical practice, language preservation has classically focused on spoken language. The current study aimed to evaluate the potential role of intra-operative assessments in the preservation of written language skills in glioma patients undergoing awake surgery. It is the first feasibility study to use a standardized and detailed Written language battery in glioma patients undergoing awakening surgery. Reading and spelling were assessed pre- and post-operatively in eleven patients. Intra-operatively, 7 cases underwent written language assessment in addition to spoken object naming. Results show that reading and spelling deficits may arise before and after glioma surgery and that written language may be differently affected than spoken language. In our case series, task-specific preservation of function was obtained in all cases when a specific written language skill was monitored intra-operatively. However, the benefits of intra-operative testing did not always generalize, and non-monitored written language tasks may not be preserved. Hence, when a specific written language skill needs to be preserved, to facilitate return to work and maintain quality of life, results indicate that intra-operative assessment of that skill is advised. An illustrative case report demonstrates how profile analyses can be used pre-operatively to identify cognitive components at risk and intra-operatively to preserve written language abilities in clinical practice.
