Speech-to-text intervention to support text production among students with writing difficulties: a single-case study in nordic countries. Disabil Rehabil Assist Technol 2024:1-20. [PMID: 38776244 DOI: 10.1080/17483107.2024.2351488] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Accepted: 04/30/2024] [Indexed: 05/24/2024]
Abstract
Studies report that speech-to-text applications (STT) may support students with writing difficulties in text production. However, existing research is sparse, shows mixed results, and lacks information on STT interventions and their applicability in schools. Therefore, this study aimed to investigate whether a systematic and intensive assistive technology intervention focusing on STT can improve text production. A modified multiple-baseline across-subject design was used involving eight middle school students, four Norwegian and four Swedish. Their STT-produced narrative texts were collected during and after the intervention and the productivity, accuracy, and text quality were analysed. Keyboarding was the baseline control condition. The results demonstrated that seven of the eight students increased text productivity and that the proportion of word-level accuracy was maintained or improved. The use of punctuation progressed in participants with poor baseline skills. Most students' STT-produced texts had at least a similar ratio of meaningfulness and text quality as keyboarding. However, the magnitude of the changes and development patterns varied, with three students showing the most notable impacts. In conclusion, this study's intervention seemed beneficial in initially instructing STT, and the progress monitoring guided individually adapted future interventions such as balancing productivity and formal language aspects. Removing the spelling barrier with STT provided an opportunity for students to improve their higher-order skills, such as vocabulary diversity and overall text quality. Furthermore, visible progress, such as the ability to produce longer texts, might motivate continued STT usage. However, such development may not always be immediate.

Twice-exceptionality unmasked: A systematic narrative review of the literature on identifying dyslexia in the gifted child. DYSLEXIA (CHICHESTER, ENGLAND) 2024; 30:e1763. [PMID: 38232949 DOI: 10.1002/dys.1763] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/10/2023] [Revised: 11/03/2023] [Accepted: 01/04/2024] [Indexed: 01/19/2024]
Abstract
In this systematic narrative review, we synthesised the small existing body of research on children who are gifted and dyslexic (G-D) in order to investigate the claim that G-D students have a unique profile, characterised by well-masked word-level reading and spelling difficulties. Our focus was on both the cognitive and academic profiles of this subgroup of twice-exceptional (2e) children and the assessment protocols used to identify them. Findings suggest that despite having processing deficits associated with dyslexia, G-D students' gifted strengths, especially those relating to oral language, may enable them to compensate for their reading difficulties, at least to an extent that they fail to meet standard diagnostic criteria. However, G-D students also perform poorly on word-level reading, reading fluency and spelling tasks when compared with both control groups and their gifted, non-dyslexic peers, providing clear evidence of impaired achievement. Findings from this review highlight the need for (a) a more nuanced approach to the assessment of students presenting with highly discrepant profiles and (b) future research into both the cognitive and academic profiles and the instructional needs of this highly able yet poorly understood group of students, whose potential may be masked and thus underestimated in the school setting.

Revisiting the definition of dyslexia. ANNALS OF DYSLEXIA 2024:10.1007/s11881-023-00295-3.

Abstract
The International Dyslexia Association definition of dyslexia was updated 20 years ago and has been referenced frequently in research and practice. In this paper, researchers from the Florida Center for Reading Research consider the components of the definition and make recommendations for revisions. These include recognizing the persistence of word-reading, decoding, and spelling difficulties, acknowledging the multifactorial causal basis of dyslexia, clarifying exclusionary factors, and denoting comorbidity with other developmental disorders. It is also suggested that the academic and psychosocial consequences of dyslexia be highlighted to reinforce a preventive service delivery model. Lastly, the inclusion of dyslexia within a specific learning disability category is supported.

Self-efficacy for writing and written text quality of upper secondary students with and without reading difficulties. Front Psychol 2023; 14:1231817. [PMID: 37809318 PMCID: PMC10557487 DOI: 10.3389/fpsyg.2023.1231817] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Accepted: 08/07/2023] [Indexed: 10/10/2023] Open
Abstract
Introduction Self-efficacy for writing (SEW) and reading ability are some of several factors that may be related to the quality of written text that students produce. The aim of the current study was (1) to explore the variation in SEW and written text quality in L1-Swedish and L2-English among upper secondary students with different reading profiles in L1 (typical reading vs. reading difficulties) and with different study backgrounds (SB1year or SB2years = one or two years of studies of Swedish and English, respectively), and in the next step (2) to explore if individual variations in L1-reading and SEW may explain variation in written text quality. Methods Participants were 100 upper secondary students (aged 17-18) with different reading profiles operationalized as typical reading and reading difficulties. Data consisted of screening for word recognition and reading comprehension, text quality results from argumentative L1- and L2-writing tasks, school information on study background in Swedish/English, and students' responses from an online survey about SEW. Results As to SEW results, an ANOVA revealed significant main effects for reading profile and study background in L1, but in L2 there was only a significant main effect for reading profile. Written text quality results indicated that there was a significant interaction effect between reading profile and study background in L1, indicating that the significant main effect for reading profile on written text quality was influenced by the group of students with reading difficulties and SB1year. There was a significant main effect for reading profile and study background on written text quality in L2. Students with reading difficulties and SB1year were the most vulnerable group, and they had the lowest scores in L1/L2 SEW and written text quality in L1 and L2. Multiple regression results indicated that word recognition and SEW contributed significantly to L1-text quality, and word recognition, reading comprehension, and SEW contributed significantly to L2-text quality. Thus, this study sheds light on the under-researched area of L1/L2 SEW and text quality of students with reading difficulties at the level of upper secondary school. Discussion Pedagogical implications are discussed and highlight the need for writing instruction across subjects in upper secondary school and for extra writing support/scaffolding for students with reading difficulties and shorter study background in the language subjects L1 (Swedish) and L2 (English).

Reading-to-Writing Mediation model of higher-order literacy. Front Psychol 2023; 14:1033970. [PMID: 37457074 PMCID: PMC10349349 DOI: 10.3389/fpsyg.2023.1033970] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2022] [Accepted: 05/30/2023] [Indexed: 07/18/2023] Open
Abstract
Introduction Writing difficulties frequently manifest comorbidly with reading challenges, and reading is implicated in particular acts of writing, such as reviewing and editing. Despite what is known, however, there remain significant barriers to understanding the nature of reading-writing relations, as few studies are comprehensive in the number and types of literacy skills evaluated. This study consists of a secondary data analysis of two studies employing structural equation modeling (SEM) to evaluate relations among reading and writing components skills independently, using the Direct and Inferential Mediation Model (DIME) of reading comprehension and Not-so-Simple View of Writing (NSVW) as theoretical frameworks. Methods We examine relations between reading and writing components from these models with a sample of upper elementary students with/at-risk for learning disabilities (n = 405). Lower-order components included word reading, vocabulary, handwriting and spelling. Higher-order components included background knowledge, reading strategies, inferencing, planning, editing, and revision. The literacy outcomes were oral and silent reading fluency, reading comprehension, and writing quality and productivity. We systematically build a Reading-to-Writing Mediation (RWM) model by first merging the DIME and NSVW components in a direct effects model (Aim 1), expanding the joint model to include reading and writing fluency (Aim 2), evaluating indirect effects between DIME and NSVW component skills (Aim 3), and finally, evaluating indirect effects with reading and writing fluency (Aim 4). Results The findings suggest that higher order fluency and comprehension skills are differentially related to writing activities and products. Discussion The pattern of results helps elucidate the mechanisms of how various reading and writing skills transfer and relate. The results have implications for targeted and implicit instruction in multicomponent interventions and the use of screeners to identify areas of risk.

Abstract
Different studies have demonstrated that people with dyslexia have difficulties in acquiring fluent reading and writing. These problems are also evident when they learn a second language. The aim of our study was to investigate if there is a linguistic transfer effect for writing in children with dyslexia when they face tasks in English (L2), as well as the possible influence of other linguistic skills (spelling, vocabulary and reading) in English (L2) and in Spanish (L1). Participants completed a series of tasks both in Spanish and English: a picture naming task, a word reading task, a word spelling task, and a written composition of which we analysed its quality through different variables provided by the Coh-metrix software. Our results revealed that children with dyslexia show similar or parallel performance in written composition in both languages, which could imply a language transfer effect from L1 and L2. Besides, basic language skills are related to the characteristics of written composition to a greater extent in English than in Spanish, suggesting the impact of these on the quality of written composition.

Abstract
Dyslexic children have impairments in working memory and manual dexterity. Studies have shown that when cognitive development has deficits, motor development is often impaired, indicating a strong interconnection between both domains, and the possibility of interference with each other's proper functioning. Thus, a new literature review is necessary to understand which components of working memory and manual dexterity are affected in dyslexic children and the possible relationship between them. This review aimed to perform a systematic review and meta-analysis to analyze both skills in dyslexic children. The protocol was carried out according to the criteria established by PRISMA being registered at PROSPERO under number CRD 42021238901. Six literature databases were searched to locate studies published between 2001 and 2021: EMBASE, ERIC, ISI Web of Science, PubMed, PsycINFO, and Scopus. 21 studies met the inclusion criteria. The findings suggest that dyslexic children have significantly poorer visuospatial and verbal working memory with more impairments in the phonological loop. No significant differences were found in manual dexterity.

Co-Occurrence of Reading and Writing Difficulties: The Application of the Interactive Dynamic Literacy Model. JOURNAL OF LEARNING DISABILITIES 2022; 55:447-464.

Abstract
This article presents the application of the interactive dynamic literacy (IDL) model (Kim, 2020b) toward understanding difficulties in learning to read and write. According to the IDL model, reading and writing are part of communicative acts that draw on largely shared processes and skills as well as unique processes and skills. As such, reading and writing are dissociable but interdependent systems that have hierarchical, interactive, and dynamic relations. These key tenets of the IDL model are applied to the disruption of reading and writing development to explain co-occurrence of reading-writing difficulties using a single framework. The following hypotheses are presented: (a) co-occurrence between word reading and spelling and handwriting difficulties; (b) co-occurrence of dyslexia with written composition difficulties; (c) co-occurrence between reading comprehension and written composition difficulties; (d) co-occurrence of language difficulties with reading difficulties and writing difficulties; (e) co-occurrence of reading, writing, and language difficulties with weak domain-general skills or executive functions such as working memory and attentional control (including attention-deficit/ hyperactivity disorder [ADHD]); and (f) multiple pathways for reading and writing difficulties. Implications are discussed.

Abstract
Background In this study, we aimed to evaluate the efficacy of chromagen lenses and compare the pre- and post-intervention outcomes among individuals with non-ocular conditions such as dyslexia and Irlen syndrome and ocular conditions such as color vision deficiency (CVD) and cone-rod dystrophy (CRD). Methodology This prospective cohort study was conducted from 2016 to 2021 among cases (seven years or older) who were diagnosed with dyslexia, Irlen syndrome, CVD, or CRD. Participants were given a short questionnaire to read, followed by asking direct questions regarding medical health history, ocular history, eyeglasses prescription, and a full orthoptics evaluation. The main outcomes were the improvement in reading speed, reading accuracy, and visual stress. Results A total of 156 patients were included in this study; 110 patients with dyslexia, 19 with Irlen syndrome, 16 with CVD, and 11 with CRD. The findings showed that the reading speed and accuracy were improved in 96.34% of patients with dyslexia and 78.9% of patients with Irlen syndrome. The use of a chromagen lens was significantly associated with visual stress improvement in 89.8% of patients (p = 0.02). Photosensitivity was significantly improved after wearing the chromagen lenses in patients with CVD (87.5%) and CRD (63.6%). Conclusions The study findings showed a positive impact of chromagen lenses on reducing visual stress, including reading speed and accuracy, in patients with dyslexia and Irlen syndrome. Photosensitivity improved in patients with Irlen syndrome and CRD. Color vision was enhanced in patients with CVD. However, further studies are required to investigate the predictors of improvement and assess the long-term efficacy of chromagen lenses on daily activities and learning skills.

Promoting Handwriting Fluency for Preschool and Elementary-Age Students: Meta-Analysis and Meta-Synthesis of Research From 2000 to 2020. Front Psychol 2022; 13:841573.

Abstract
Handwriting is a complex activity that involves continuous interaction between lower-level handwriting and motor skills and higher-order cognitive processes. It is important to allocate mental resources to these high-order processes since these processes place a great demand on cognitive capacity. This is possible when lower-level skills such as transcription are effortlessness and fluent. Given that fluency is a value in virtually all areas of academic learning, schools should provide instructional activities to promote writing fluency from the first stages of learning to write. In an effort to determine if teaching handwriting enhances writing fluency, we conducted a systematic and meta-analytic review of the writing fluency intervention literature. We selected 31 studies: 21 true and quasi-experimental studies, 4 single-group design, 3 single-subject design, and 3 non-experimental studies, conducted with K-6 students in a regular school setting. A total of 2,030 students participated in these studies. When compared to no instruction or non-handwriting instructional conditions, teaching different handwriting intervention programs resulted in statistically significant greater writing fluency (ES = 0.64). Moreover, three specific handwriting interventions yielded statistically significant results in improving writing fluency, when compared to other handwriting interventions or to typical handwriting instruction conditions: handwriting focused on training timed transcription skills (ES = 0.49), multicomponent handwriting treatments (ES = 0.40), and performance feedback (ES = 0.36). There were not enough data to calculate the impact of sensory-motor and self-regulated strategy handwriting interventions on writing fluency. The significance of these findings for implementing and differentiating handwriting fluency instruction and guiding future research will be discussed.

Abstract
In recent years, evidence has been provided that individuals with dyslexia show alterations in the anatomy and function of the auditory cortex. Dyslexia is considered to be a learning disability that affects the development of music and language capacity. We set out to test adolescents and young adults with dyslexia and controls (N = 52) for their neurophysiological differences by investigating the auditory evoked P1–N1–P2 complex. In addition, we assessed their ability in Mandarin, in singing, their musical talent and their individual differences in elementary auditory skills. A discriminant analysis of magnetencephalography (MEG) revealed that individuals with dyslexia showed prolonged latencies in P1, N1, and P2 responses. A correlational analysis between MEG and behavioral variables revealed that Mandarin syllable tone recognition, singing ability and musical aptitude (AMMA) correlated with P1, N1, and P2 latencies, respectively, while Mandarin pronunciation was only associated with N1 latency. The main findings of this study indicate that the earlier P1, N1, and P2 latencies, the better is the singing, the musical aptitude, and the ability to link Mandarin syllable tones to their corresponding syllables. We suggest that this study provides additional evidence that dyslexia can be understood as an auditory and sensory processing deficit.

Abstract
In Saudi Arabia, the COVID-19 pandemic forced students with dyslexia to complete their learning through online applications, like their peers without dyslexia. This study explores the influence of assistive technology (AT) on improving the visual perception (VP) and phonological processing (PhP) abilities of students with dyslexia. Three learning applications were used (Google Classroom, Zoom, and Quizlet) as AT platforms. A quantitative approach was adopted based on a quasi-experimental design. Single-subject experimental methods were used to examine the influence of AT on improving students' VP, PhP, and frequency of access (FA). Fourteen students with dyslexia who were selected as participants through purposeful sampling were divided into two experimental groups based on gender. The results showed that AT influenced the VP, PhP, and FA in both experimental groups. Girls scored higher than boys in VP, PhP, and FA, and a positive correlation was found between VP and PhP with AT applications among girls and boys. A simple linear regression analysis showed that a significant and positive relationship exists between FA and the VP and PhP abilities of students with dyslexia through AT applications.

Abstract
Background: In school, children are required to perform a range of
handwriting tasks. The writing needs to be legible to the child and other readers. The aim
of this study was to examine handwriting legibility across different writing tasks and to
explore which components might predict overall handwriting legibility. Methods: This was a secondary analysis of data from 148 school-aged children
across writing scripts obtained from the Detailed Assessment of Speed of Handwriting:
copying-best, copying-quickly and free-writing. Results: Results showed that letter formation was the major predictor of the
total HLS score, and significant differences in handwriting legibility were found across
the three tasks. Conclusions: The HLS is a practical tool that can benefit occupational
therapists who work in schools by assessing handwriting legibility across different
handwriting tasks.

Abstract
The purpose of this study was to investigate New Jersey educators' dyslexia knowledge and misconceptions, professional development perceptions and needs, and perceived preparedness regarding teaching students with dyslexia. A second purpose was to investigate what factors predicted New Jersey educators' knowledge about dyslexia. A total of 705 in-service educators completed a survey about their dyslexia knowledge, perceived preparedness, and professional development perceptions. Participants had accurate overall knowledge about dyslexia, but some prevailing misconceptions were still present. The greatest predictor of dyslexia knowledge was years of experience in working with students with dyslexia. Reading specialists, educators with greater perceived preparedness and those educators who had training in multi-sensory approaches to instruction had significantly more dyslexia knowledge than other educators. Approximately half of the participants felt prepared to teach students with dyslexia and that working with students with dyslexia prepared them the most. Participants perceived that multi-sensory approaches were the most effective professional development and their undergraduate education was the least effective. Most participants were in support of further professional development on the topic of dyslexia. Implications for in-service educators' professional development and future research directions are discussed.

Abstract
Research suggests that executive function, motivation, transcription, and composition processes are implicated in the writing quality and productivity of children with and without learning difficulties. However, numerous components embedded within these constructs create both conceptual and empirical challenges to the study of written expression. These challenges are reflected in the writing research by way of poor delineation of constructs and insufficient distinction among domain general resources (e.g. working memory) versus processes related to the academic domain of writing (e.g. pre-planning), as well as among lower- (e.g. handwriting) and higher-order (e.g. editing) writing-specific processes. The current study utilizes the Not-so-Simple View of Writing (NSVW) as an organizing framework for examining the relations among multiple components, correlates, and attributes of writing in a sample of struggling readers/writers (n = 402) in grades 3-5. Data were collected on measures of (a) handwriting, spelling, planning, revision, and editing, derived from the Test of Oral Written Language (TOWL-4), (b) executive function derived from the NIH Examiner, and (c) motivation/self-efficacy derived from the Student Contextual Learning Scale. Structural equation modeling was utilized to test direct and indirect relations in the NSVW model. Results showed generally moderate correlations among observed/latent variables and found support for relations among writing-specific processes. Domain-general resources (executive function and motivation/self-efficacy) were related to spelling directly and indirectly to writing. Domain-specific processes (handwriting, spelling, planning, editing, and revision) were related to writing. The results have implications for explicit instruction of writing processes and for future research on empirical models.

Abstract
Background About 6.2 million adults in Germany cannot read and write properly despite attending school for several years. They are considered to be functional illiterates (FI). Since the ability to read and write is crucial for being employed and socially accepted, we developed a special literacy training to overcome these deficits. Methods In this study, we investigate training-related changes in intrinsic functional connectivity (iFC) at rest in a group of 20 FI and 20 adult normal readers using resting state functional magnetic resonance imaging (rsfMRI). We used independent component analysis (ICA) to define different networks. Results Before training, the between group analysis showed increased iFC in FI in a left-fronto-parietal network (LFPN; anterior insula, medial frontal cortex, lateral and frontal parietal regions) and in the Basal Ganglia network (BGN: thalamus, caudate, putamen, pallidum, amygdala, supplementary motor cortex and cingulate gyrus). Furthermore, the Visual Network-1 (VN1; temporal occipital fusiform gyrus, lateral occipital cortex, occipital pole, lingual gyrus, thalamus) showed decreased iFC in FI. After training the FI group showed reversal of the “hyperconnectivity” in middle frontal gyrus and in the frontal orbital cortex and between supramarginal gyrus and the BGN. Furthermore, functional connectivity increased in FI VN1 (lateral occipital cortex, insular cortex). These changes in connectivity correlated with gains in reading speed and spelling accuracy. Conclusions These findings show that poor reading and writing abilities are associated with abnormalities in iFC in several brain areas subserving cognitive processes important for reading. Intensive literacy training induces changes in the functional connectivity between and within neural networks important for literacy skills.

What Speech-Language Pathologists Need to Know About Dyslexia. Lang Speech Hear Serv Sch 2018; 49:759-761. [DOI: 10.1044/2018_lshss-dyslc-18-0098] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2018] [Accepted: 10/21/2018] [Indexed: 11/09/2022] Open
Abstract
Purpose
The purpose of this clinical forum is to provide a broad survey of up-to-date, evidence-based information about dyslexia that can be readily applied to clinical practice by speech-language pathologists. Topics include (a) theoretical and clinical frameworks for understanding dyslexia in relation to other language-based communication disorders, (b) the neurobiological basis of dyslexia, (c) the current state of dyslexia legislation, (d) issues around identification of dyslexia, (e) and evidence-based reviews of instruction for reading and writing.
Conclusion
Though there have been numerous papers written on the topic of dyslexia, this clinical forum is unique in that it is the only combination of articles to focus on dyslexia with the speech-language pathologist in mind.
