Neural bases of reading fluency: A systematic review and meta-analysis.

Reading fluency, the ability to read quickly and accurately, is a critical marker of successful reading and is notoriously difficult to improve in reading disabled populations. Despite its importance to functional literacy, fluency is a relatively under-studied aspect of reading, and the neural correlates of reading fluency are not well understood. Here, we review the literature of the neural correlates of reading fluency as well as rapid automatized naming (RAN), a task that is robustly related to reading fluency. In a qualitative review of the neuroimaging literature, we evaluated structural and functional MRI studies of reading fluency in readers from a range of skill levels. This was followed by a quantitative activation likelihood estimate (ALE) meta-analysis of fMRI studies of reading speed and RAN measures. We anticipated that reading speed, relative to untimed reading and reading-related tasks, would harness ventral reading pathways that are thought to enable the fast, visual recognition of words. The qualitative review showed that speeded reading taps the entire canonical reading network. The meta-analysis indicated a stronger role of the ventral reading pathway in rapid reading and rapid naming. Both reviews identified regions outside the canonical reading network that contribute to reading fluency, such as the bilateral insula and superior parietal lobule. We suggest that fluent reading engages both domain-specific reading pathways as well as domain-general regions that support overall task performance and discuss future avenues of research to expand our understanding of the neural bases of fluent reading.

Do Oral and Silent Word-Reading Fluency Rely on the Same Cognitive-Linguistic Skills? Evidence from a Cross-Sectional Study in Greek.

Researchers tend to use oral- and silent-reading fluency measures interchangeably and to generalize research findings across reading modes, especially from oral to silent reading. In this study, we sought to examine if oral and silent word-reading fluency rely on the same cognitive-linguistic skills. Three hundred and forty-five Greek children (80 from Grade 2, 85 from Grade 4, 91 from Grade 6, and 89 from Grade 10) were assessed on measures of general cognitive ability, speed of processing, phonological awareness, rapid automatized naming, orthographic knowledge, articulation rate, and word-reading fluency (oral and silent). Results of hierarchical regression analyses revealed that phonological awareness was a unique predictor of both reading outcomes in Grade 2 and orthographic knowledge was a unique predictor of both reading outcomes in Grades 4, 6, and 10. However, rapid automatized naming predicted only oral word-reading fluency. These findings suggest that silent and oral word-reading fluency do not necessarily rely on the same cognitive-linguistic skills at the same grade level and we need to exercise some caution when we generalize the findings across reading modes.

Academic and behavior combined support: A single-case practice-based replication study.

The purpose of this research was to conduct a practice-based replication of Academic and Behavior Combined Support (ABC Support), a previously developed and experimentally evaluated supplemental intervention that merges a combined focus on reading fluency and academic engagement. In the present study, a school-based interventionist and data collector had access to implementation resources online and participated in virtual training and coaching. Four Grade 2 students received the ABC Support intervention for 6 weeks in their school. Students' oral fluency on training and non-training reading passages, as well as occurrence of engagement and disruptive behaviors during universal reading instruction, were measured repeatedly across baseline, intervention, and follow-up phases in a multiple-baseline design. In concert with prior empirical findings on ABC Support, analyses revealed improvement from baseline to intervention for both reading and behavior outcomes, as well as from baseline to follow-up assessments. Empirical contributions of the study are offered within the context of replication research and an implementation science perspective. We also emphasize the importance of telecommunication for practice-based research evaluation of interventions.

Incorporating calibration errors in oral reading fluency scoring.

Oral reading fluency (ORF) assessments are commonly used to screen at-risk readers and evaluate interventions' effectiveness as curriculum-based measurements. Similar to the standard practice in item response theory (IRT), calibrated passage parameter estimates are currently used as if they were population values in model-based ORF scoring. However, calibration errors that are unaccounted for may bias ORF score estimates and, in particular, lead to underestimated standard errors (SEs) of ORF scores. Therefore, we consider an approach that incorporates the calibration errors in latent variable scores. We further derive the SEs of ORF scores based on the delta method to incorporate the calibration uncertainty. We conduct a simulation study to evaluate the recovery of point estimates and SEs of latent variable scores and ORF scores in various simulated conditions. Results suggest that ignoring calibration errors leads to underestimated latent variable score SEs and ORF score SEs, especially when the calibration sample is small.

Mediators of working memory and reading in a sample of children with reading difficulty: The roles of phonemic awareness and rapid automatized naming.

Working memory (WM) has been consistently linked to reading. However, the mechanism(s) linking WM to reading remain unclear. WM may indirectly exert an effect onto reading through mediators such as phonemic awareness (PA) and/or rapid automatized naming (RAN). In a sample of children with reading difficulty (n = 117), separate mediation analyses tested direct and indirect (through PA and RAN) effects of WM on untimed word decoding and recognition (i.e., basic reading skills) and timed word decoding and recognition (i.e., reading fluency). WM exerted a direct effect on basic reading skills and reading fluency. For basic reading skills, there was a significant indirect effect of WM on reading through the mediation of PA (but not through RAN). By contrast, for reading fluency, there was a significant indirect effect of WM on reading through the mediation of RAN (but not through PA). Findings reinforce the importance of WM, PA, and RAN for broad reading skills, while offering a mechanistic explanation for why poor PA and/or RAN may differentially lead to reading difficulty.

The Relationships of Oral Reading Fluency at Word, Sentence, and Passage Levels and Reading Comprehension in Chinese.

This study aims to expand our understanding of the relations of oral reading fluency at word, sentence, and passage levels to reading comprehension in Chinese-speaking secondary school-aged students. In total, 80 participants (46 males and 34 females) ranging from 13 to 15 years old joined this study and were tested on tasks of oral reading fluency at three levels, reading comprehension, and nonverbal IQ. Our results showed a clear relationship from fluency at the level of the word to the sentence and then the passage in oral reading fluency as well as both the direct and indirect importance of word-level oral reading fluency in reading comprehension. Only the indirect effect from word-level oral reading fluency to reading comprehension through passage-level oral reading fluency was significant. Our findings suggest that sentence-level oral reading fluency is the crucial component to reading comprehension in Chinese. Additionally, recognition of the potential value of unique features, such as syntactic awareness and word segment accuracy, that happen at the sentence level should be integrated into instructional activities for reading.

Localized alterations in cortical thickness and sulcal depth of the cingulo-opercular network in relation to lower reading fluency skills in children with dyslexia.

The traditional models of reading development describe how language processing and word decoding contribute to reading comprehension and how impairments in word decoding, a defining feature of dyslexia, affect reading comprehension outcomes. However, these models do not include word and sentence reading (contextual reading) fluency, both of which engage executive functions, with notably decreased performance in children with dyslexia. In the current study, we compared cortical thickness and sulcal depth (CT/SD) in the cingulo-opercular (CO) executive functions brain network in children with dyslexia and typical readers and examined associations with word vs. contextual reading fluency. Overall, CT was lower in insular regions and higher in parietal and caudal anterior cingulate cortex regions in children with dyslexia. Children with dyslexia showed positive correlations between word reading fluency and CT/SD in insular regions, whereas no significant correlations were observed in typical readers. For sentence reading fluency, negative correlations with CT/SD were found in insular regions in children with dyslexia, while positive correlations with SD were found in insular regions in typical readers. These results demonstrate the differential relations between word and sentence reading fluency and anatomical circuitry supporting executive functions in children with dyslexia vs. typical readers. It also suggests that word and sentence reading fluency, relate to morphology of executive function-related regions in children with dyslexia, whereas in typical readers, only sentence reading fluency relates to morphology of executive function regions. The results also highlight the role of the insula within the CO network in reading fluency. Here we suggest that word and sentence reading fluency are distinct components of reading that should each be included in the Simple View of Reading traditional model.

The effect of attention shifting on Chinese children's word reading in primary school.

BACKGROUND: This study explored the effects of attention shifting on Chinese children's word reading. OBJECTIVE: The sample consisted of 87 fourth-grade children from Shaoxing City, China. METHODS: The students completed measures of the attention shifting task, reading accuracy test, reading fluency test, and rapid automatized naming test. RESULTS: The results showed that reading fluency was significantly correlated with attention shifting scores, specifically with tag1 and tag6 (ps < 0.05). The reading accuracy score was also significantly correlated with tag6 (p < 0.05). According to the regression analysis of attention shifting on word reading, even when controlling for rapid automatic naming, attention shifting significantly affected word reading fluency at approximately 600 ms (p = .011). Attention shifting did not affect children's word reading accuracy. SHORT CONCLUSION: These findings suggest that attention shifting is significantly associated with children's word reading. Educators should focus on developing children's attention shifting to improve their word reading ability.

Equating Oral Reading Fluency Scores: A Model-Based Approach.

Words read correctly per minute (WCPM) is the reporting score metric in oral reading fluency (ORF) assessments, which is popularly utilized as part of curriculum-based measurements to screen at-risk readers and to monitor progress of students who receive interventions. Just like other types of assessments with multiple forms, equating would be necessary when WCPM scores are obtained from multiple ORF passages to be compared both between and within students. This article proposes a model-based approach for equating WCPM scores. A simulation study was conducted to evaluate the performance of the model-based equating approach along with some observed-score equating methods with external anchor test design.

Executive functions underlie word reading and reading fluency in Chinese children with attention deficit/hyperactivity disorder, reading disabilities, and comorbid attention deficit/hyperactivity disorder and reading disabilities.

The current study examined the executive function (EF) deficits and their roles in reading in one hundred and four Cantonese-speaking children with typical development, reading disabilities (RD), ADHD, and comorbid ADHD and RD (ADHD + RD). Children's EF and reading skills were measured. Analysis of variance results showed that all children with disorders manifested deficits in verbal and visuospatial short-term and working memory and behavioral inhibition. Moreover, children with ADHD and ADHD + RD also exhibited deficits in inhibition (IC and BI) and cognitive flexibility. These findings demonstrated that the EF deficits in Chinese children with RD, ADHD, and ADHD + RD are similar to those in their counterparts using alphabetic languages. However, children with ADHD + RD displayed more severe deficits in visuospatial working memory compared to children with RD and ADHD, which was inconsistent with that observed in children using alphabetic languages. Regression analysis results showed that verbal short-term memory was a significant predictor for both word reading and reading fluency in children with RD and ADHD + RD. Moreover, behavioral inhibition significantly predicted reading fluency in children with ADHD. These findings also agreed with previous studies. Collectively, the results of the current study showed that the EF deficits and their roles in reading found in Chinese children with RD, ADHD, and ADHD + RD are mainly consistent with children using alphabetic languages. However, more studies are still needed to confirm these findings, especially comparing the severity of working memory among these three disorders.

Educators should focus on developing children's attention shifting to improve their word reading ability.

Does early exposure to spoken and sign language affect reading fluency in deaf and hard-of-hearing adult signers?

Introduction: Early linguistic background, and in particular, access to language, lays the foundation of future reading skills in deaf and hard-of-hearing signers. The current study aims to estimate the impact of two factors - early access to sign and/or spoken language - on reading fluency in deaf and hard-of-hearing adult Russian Sign Language speakers. Methods: In the eye-tracking experiment, 26 deaf and 14 hard-of-hearing native Russian Sign Language speakers read 144 sentences from the Russian Sentence Corpus. Analysis of global eye-movement trajectories (scanpaths) was used to identify clusters of typical reading trajectories. The role of early access to sign and spoken language as well as vocabulary size as predictors of the more fluent reading pattern was tested. Results: Hard-of-hearing signers with early access to sign language read more fluently than those who were exposed to sign language later in life or deaf signers without access to speech sounds. No association between early access to spoken language and reading fluency was found. Discussion: Our results suggest a unique advantage for the hard-of-hearing individuals from having early access to both sign and spoken language and support the existing claims that early exposure to sign language is beneficial not only for deaf but also for hard-of-hearing children.

Reading fluency as the bridge between decoding and reading comprehension in Chinese children.

Purpose: Reading fluency has been considered an essential component of reading comprehension, but it is yet to be examined in a reading model in a non-alphabetic writing system. This study investigated whether reading fluency could be identified as a separate construct from decoding and examined the unique role of reading fluency in the Simple View of Reading (SVR). Method: A total of 342 Cantonese-speaking Chinese children in grades 3-5 were recruited to participate in the study. They were assessed on word reading accuracy and fluency, morphological awareness, vocabulary knowledge, and reading comprehension. Results: The confirmatory factor analysis results confirmed that reading fluency is a separate factor from decoding, linguistic comprehension, and reading comprehension. Furthermore, the structural equation modeling results revealed that reading fluency is a significant predictor of reading comprehension and a mediator between decoding and reading comprehension in the extended SVR model. Conclusion: The findings extended previous research in alphabetic languages and supported reading fluency as the bridge between decoding and reading comprehension. The present study highlighted the importance of reading fluency in Chinese reading acquisition in a theoretical framework.

WordSword: An Efficient Online Word Reading Assessment for Global English.

The development of efficient and reliable online assessments has become increasingly important in the digital era. We developed a 10-min online word reading assessment of global English based on the existing paper-and-pencil version of our English silent word reading test. The test includes two parts, namely, random word recognition and contextual word reading. A total of 889 participants (437 children and 392 adults; 62.7% female) took part in the study. They were from various regions including mainland China, Hong Kong SAR, Macau SAR, Poland, the United States, and the Philippines. Reliability and validity analyses on various demographics samples (by age and country/region of origin) demonstrated that the WordSword Test is highly reliable and valid (e.g., the correlation of this test with other English reading measures were above .80). Education level was positively correlated with test performance, while the correlations between age and test performance were not consistent. Ninety-seven children participants also took the paper-and-pencil version of the WordSword Test. The correlation between performances on the online and paper-and-pencil versions of the test was .879, one year apart. With more children and adults taking the WordSword Test, we ultimately hope to establish norms by area, grade level, and age.

Development of reading fluency and metacognitive knowledge of reading strategies during reciprocal teaching: do these changes actually contribute to reading comprehension?

The study examined the effect of reciprocal teaching on students' reading comprehension, reading fluency, and metacognitive knowledge of reading strategies, especially among students with learning difficulties. The special focus was to assess how the increase in reading fluency and metacognitive knowledge during the intervention contributes to the reading comprehension outcome. The sample consisted of 301 Grade 3 students, of whom 77 had learning difficulties. Analyzes of (co)variances were used for estimating the effects of reciprocal teaching on the development of reading comprehension, reading fluency, and metacognitive knowledge. Multigroup path analysis was used for testing the effect of increase in reading fluency and metacognitive knowledge on reading comprehension. We found reciprocal teaching had a positive effect on reading comprehension, especially for students with learning difficulties. Reading fluency and metacognitive knowledge improved significantly, but similarly in both the intervention and control groups. However, the increase in metacognitive knowledge only contributed to reading comprehension in the intervention group, not in the control group. The study sheds light on the cognitive and metacognitive mechanisms underlying students' reading comprehension process, emphasizing metacognitive knowledge and especially the systematic practice of reading strategies as key factors in improving reading comprehension.

Reading-to-Writing Mediation model of higher-order literacy.

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.

Understanding variation in prospective poor decoders: A person-centred approach from kindergarten to Grade 2.

In the present study, we aimed to clarify variation in prospective poor decoders by studying the development of their word decoding skills during the first 1½ years of formal reading education and their unique pre-reading profiles before the onset of formal reading education. Using structural equation modelling and a factorial mixed model analysis of variance (ANOVA), we found autoregression and growth in the word decoding efficiency of prospective poor decoders (n = 90) and matched prospective adequate decoders (n = 90) in first and second grade. However, the gap between the two groups widened over time. Next, we zoomed in on the group of poor decoders by retrospectively studying their individual variation regarding cognitive and linguistic pre-reading skills. Using latent profile analysis, we found three distinct pre-reading profiles: (1) Poor PA, Letter Knowledge, RAN, and Verbal STM; (2) Poor PA and Letter Knowledge; and (3) Poor RAN. Together, these findings suggest that reading difficulties emerge at the intersection of multiple risk factors which can be detected in kindergarten, and that these reading problems persist throughout early reading education.

The Relationship of Oral Reading Fluency Endurance to Comprehension in an Intermediate Depth Orthography / [La relación entre la resistencia en la fluidez lectora y la comprensión en una ortografía de profundidad intermedia]

One-minute oral reading fluency (ORF) tests are widely used, but concerns have been raised regarding whether readers are able to maintain their performance if asked to read for a larger period. The main goals of this study were to investigate whether students are able to maintain their ORF performance in a three-minute task and whether scores measured at one and at three minutes are equally good predictors of the performance in a standardized reading comprehension measure. The sample was composed of 159 Portuguese primary school students (grades 2-4). The results suggested that the number of words read correctly (WRC) declined across reading time and that three-minute mean score underestimated fluency in all grade levels compared to a one-minute reading score. The WRC measured either at one minute or using a three-minute average score was an equal predictor of reading comprehension in all grades. Implications for theory and practice are discussed.(AU)

Las pruebas de fluidez lectora de un minuto son muy utilizadas, pero se ha planteado la preocupación de si los lectores son capaces de mantener su rendimiento si se les pide que lean durante un período más largo. Los objetivos principales de este estudio han sido investigar si los estudiantes son capaces de mantener su rendimiento de fluidez lectora en una tarea de tres minutos y si las puntuaciones medidas a uno y a tres minutos son igualmente predictoras del rendimiento en una medida estandarizada de comprensión lectora. La muestra estaba compuesta por 159 alumnos portugueses de primaria (2º a 4º curso). Los resultados sugieren que el número de palabras leídas correctamente (PLC) disminuyó a lo largo del tiempo de lectura y que la puntuación media a los tres minutos subestimó la fluidez en todos los cursos en comparación con la puntuación de un minuto de lectura. El PLC medido ya sea en un minuto o utilizando una puntuación media de tres minutos fue un predictor igual de la comprensión lectora en todos los cursos. Se discuten las implicaciones para la teoría y la práctica.(AU)

Influence of letter shape on readers' emotional experience, reading fluency, and text comprehension and memorisation.

Introduction: The amount of educational material delivered to pupils and students through digital screens is increasing. This method of delivering educational materials has become even more prevalent during the COVID-19 pandemic. To be as effective as possible, educational material must be properly designed not only in terms of content, but also in terms of form, e.g., the typeface. The present study investigated the effect of letter shape on readers' feelings of pleasantness during reading, reading fluency, and text comprehension and memorisation. Methods: To find out whether age influences the effects of typeface shape on reading measures, we divided the participants into a group of less experienced readers (children) and more experienced readers (adults). Both groups read texts in eight different typefaces: four of them were round or in rounded shape, and four were angular or in pointed shape. With an eye-tracker, the reading speed and the number of regressive saccades were recorded as measures of reading fluency and changes in pupil size as an indicator of emotional response. After reading each text, the participants rated the pleasantness of the typeface, and their comprehension and memorisation of texts were checked by asking two questions about the text content. Results: We found that compared to angular letters or letters in pointed shape, round letters or letters in round shape created more pleasant feelings for readers and lead to a faster reading speed. Children, as expected, read more slowly due to less reading experiences, but, interestingly, had a similar number of regressive saccades and did not comprehend or remember the text worse than university students. Discussion: We concluded that softer typefaces of rounder shapes should be used in educational materials, as they make the reading process easier and thus support the learning process better for both younger and adult readers. The results of our study also showed that a comparison of findings of different studies may depend on the differences among the used letter shapes.

Translation and cultural adaptation of the HELPS Reading Fluency Program into Brazilian Portuguese: A report of systematic adaptation processes and initial evidence of efficacy.

Introduction: Across multiples languages, research demonstrates the important relationship between reading fluency and comprehension. Put simply, a fluent reader has greater attention and memory resources to use higher-order functions in reading, resulting in better comprehension of text. Some reading fluency interventions have shown positive results in improving students' text reading fluency and comprehension; however, this research has predominantly been conducted with English-speaking students. For instance, until this report, a comprehensive search revealed only one prior study that evaluated an intervention strategy designed to improve students' reading fluency in Brazilian Portuguese and no prior studies evaluated an intervention program with that population of students. Methods: The main goals of this two-part project were to (a) systematically translate, culturally adapt, and pilot test the Helping Early Literacy with Practice Strategies (HELPS) reading fluency program for use in Brazilian Portuguese (referred to as, HELPS-PB); and (b) conduct a preliminary quasi-experimental study of the HELPS-PB program with 23 students in grades 3 to 5 who needed a reading fluency intervention. Results and Discussion: This report documents the processes and successful adaptation of existing English- and Spanish-versions of HELPS into a new HELPS-PB program. It also offers preliminary evidence showing that students receiving HELPS-PB significantly improved their text reading fluency comparted to students in a control group. Implications for research, practice, and the adaptation of reading fluency programs into other languages are discussed.
