Effects of fluency, oral language, and executive function on reading comprehension performance

Reading disability (RD) typically consists of deficits in word reading accuracy and/or reading comprehension. While it is well known that word reading accuracy deficits lead to comprehension deficits (general reading disability, GRD), less is understood about neuropsychological profiles of children who exhibit adequate word reading accuracy but nevertheless develop specific reading comprehension deficits (S-RCD). Establishing the underlying neuropsychological processes associated with different RD types is essential for ultimately understanding core neurobiological bases of reading comprehension. To this end, the present study investigated isolated and contextual word fluency, oral language, and executive function on reading comprehension performance in 56 9- to 14-year-old children [21 typically developing (TD), 18 GRD, and 17 S-RCD]. Results indicated that TD and S-RCD participants read isolated words at a faster rate than participants with GRD; however, both RD groups had contextual word fluency and oral language weaknesses. Additionally, S-RCD participants showed prominent weaknesses in executive function. Implications for understanding the neuropsychological bases for reading comprehension are discussed.

Reading disorders in primary progressive aphasia: A behavioral and neuroimaging study

Previous neuropsychological studies on acquired dyslexia revealed a double dissociation in reading impairments. Patients with phonological dyslexia have selective difficulty in reading pseudo-words, while those with surface dyslexia misread exception words. This double dissociation in reading abilities has often been reported in brain-damaged patients, but it has not been consistently shown in patients with neurodegenerative diseases.In this study, we investigated reading impairments and their anatomical correlates in various neurodegenerative diseases. First, we performed a behavioral analysis to characterize the reading of different word types in primary progressive aphasia (PPA). Then, we conducted a voxel-based morphometry neuroimaging study to map the brain areas in which gray matter volume correlated with the accurate reading of exception and pseudo-words.The results showed a differential pattern of exception and pseudo-word reading abilities in different clinical variants of PPA. Patients with semantic dementia, a disorder characterized by selective loss of semantic memory, revealed a pattern of surface dyslexia, while patients with logopenic/phonological progressive aphasia, defined by phonological loop deficits, showed phonological dyslexia. Neuroimaging results showed that exception word reading accuracy correlated with gray matter volume in the left anterior temporal structures, including the temporal pole, the anterior superior and middle temporal and fusiform gyri, while pseudo-word reading accuracy correlated with left temporoparietal regions, including the posterior superior and middle temporal and fusiform gyri, and the inferior parietal lobule.These results suggest that exception and pseudo-word reading not only rely upon different language mechanisms selectively damaged in PPA, but also that these processes are sustained by separate brain structures.

Reading Success

Reading Success is an individualized teacher-guided literacy program proven for 663 students who experienced difficulty with reading. The students had learning disabilities, mild mental retardation, and behavior challenges; were at risk for school failure; or were transitioning from speaking Spanish to English and experiencing literacy problems. Pupil progress data, as measured by progress over time in various reading curricula, reflected student gains of a half year to more than 3 years per year of instruction. Monthly curricular progress data ranged from 0.03 to 6.80 months’ gain per month of instruction. Many students showed equivalent gains on standardized informal reading inventories, with some passing a statewide test for the first time. Thirty-five special education students returned to regular education programs. All students received the basic lesson, reflecting reading research-based practices. Some students received specialized interventions that focused on three critical reading behaviors (word reading accuracy, reading speed, reading comprehension) and written language (composition, mechanical skills).

Code-oriented instruction for kindergarten students at risk for reading difficulties: a replication and comparison of instructional groupings

The purposes of this study were to replicate previous research on phonics-based tutoring in kindergarten and to compare treatment effects for students who received individual instruction compared to instruction in dyads. Thirty classroom teachers from 13 urban elementary schools referred at-risk students for participation. Students who met screening criteria were quasi-randomly assigned, within classroom, to one of three conditions: individual tutoring (n = 22), tutoring in dyads (n = 32), or no tutoring (n = 22, classroom instruction only). Twenty-one paraeducators provided 18 weeks of explicit instruction in phonemic skills and the alphabetic code to students during the latter half of kindergarten. Multilevel model results showed that tutored students outperformed non-tutored controls on posttest measures of phonological awareness, word reading accuracy, oral reading fluency, spelling, and comprehension. However, no significant differences were found between the two tutored groups on any measure, suggesting that code-oriented tutoring for pairs of students is a viable alternative to the gold standard of individual instruction.

Differences in the correlates of reading accuracy and speed in young Dutch readers

In this study the differential relationships of phonological awareness and rapid naming (serial and discrete) with reading accuracy and speed were examined. Participants were 52 Dutch second grade children. Measures of phonological awareness, serial rapid naming (objects and digits) and discrete rapid digit naming were administered. Also, various aspects of reading ability were measured: reading accuracy and speed for words and nonwords, and text reading fluency. The results indicated that second grade Dutch children were not fully accurate readers. A clear dissociation was found between phonological awareness and serial rapid naming, the former being mainly related to reading accuracy and the latter to reading speed. However, both were related to text reading fluency. A dissociation was also observed between serial and discrete rapid digit naming. The latter was particularly associated with word reading speed. The implications for the interpretation of cross-linguistic studies on the correlates of reading are discussed.

Using precision teaching to increase the fluency of word reading with problem readers

This study describes the effectiveness of a brief intervention aimed at increasing the rate (frequency) of reading common English words for five pupils who were experiencing problems with reading. The intervention employed frequency-building procedures aimed at increasing the rate at which the children could read words accurately, and precision teaching (PT) to monitor the effectiveness of the intervention. The children in the treatment as usual (TAU) condition received the standard reading support during the same period. All of the pupils’ were tested at pre- and post-intervention on the frequency at which they could read words accurately, and all were given a standardised reading test. Following intervention the outcome measures for fluency were taken: maintenance, endurance, application, and stability. All five of the PT children increased their rate of accurate word reading, and two made significant gains on the standardised tests of reading; however, the TAU children did not improve on any of the measures. The study provides additional evidence supporting the effectiveness of PT and frequency-building procedures, and that successful intervention need not require expensive or time-consuming resources.

Do children who acquire word reading without explicit phonics employ compensatory learning? Issues of phonological recoding, lexical orthography, and fluency

Two studies were conducted across three countries to examine samples of beginning readers without systematic explicit phonics who had reached the same level of word reading accuracy as comparison samples with high and moderate explicit phonics. Had they employed any compensatory learning to reach that level? Four hypotheses of compensatory learning or performance were tested on the samples, all of which represented the lower half of the normative distribution of word reading accuracy. The two samples without explicit phonics received teaching that centered on story text reading and some receptive phonics that arose from this text reading. They did not compensate by relatively greater use of a larger psycholinguistic grain size in the form of rime units. Nor did they compensate by trading off comprehension for text word reading accuracy. In a microtraining study, they showed no compensation in proficiency of initial learning of lexical orthographic representations. For all samples, this initial learning was less effective with spelling than reading training trials. In reading text, the samples without explicit phonics did not compensate by trading off speed for accuracy, or comprehension. On the contrary, they read text faster than the explicit phonics samples. The extra classroom instruction time available to them for text reading, with the consequential extra exposure and practice of word reading, would explain this result.

The relationship between attention, executive functions and reading domain abilities in attention deficit hyperactivity disorder and reading disorder: a comparative study

Co-morbidity of attention deficit hyperactivity disorder (ADHD) and reading disorder (RD) is frequent. The objective of this investigation was to assess the potential uniqueness of co-morbid ADHD + RD and extend existing findings to the Hebrew language. A parallel group design with post-hoc analysis of group differences was employed comparing four groups of children (19 ADHD, 17 RD, 27 ADHD + RD, and 23 controls) on reading measures, attention and executive functions (EF) as well as functions of phonemic awareness and rapid naming. Forward stepwise regressions were run in order to delineate significant relationships between phonemic awareness, rapid naming, attention and EF with outcome variables of reading. The co-morbid group shared the basic characteristic impairments in attention and executive functions with the pure ADHD group and in reading domain functions with the pure RD group. In addition, this group showed unique deficits in rapid naming and a more severe impairment in working memory. Forward stepwise regression pointed to associations between executive functions and word reading accuracy in children with ADHD, in contrast to associations between linguistic functions and word accuracy in non-ADHD. The combination of cognitive deficits in the subgroup of children with both ADHD and RD and the relationship between accuracy in word decoding and executive functions shown for the ADHD groups point to a distinct clinical profile of the co-morbid condition. Attention and EF should be considered in the diagnosis of RD and in the remediation protocol.

The relationship between phonological awareness and word reading accuracy in Oriya and English: A study of Oriya‐speaking fifth‐graders

This study investigated the relationships between phonological awareness and reading in Oriya and English. Oriya is the official language of Orissa, an eastern state of India. The writing system is an alphasyllabary. Ninety‐nine fifth grade children (mean age 9 years 7 months) were assessed on measures of phonological awareness, word reading and pseudo‐word reading in both languages. Forty‐eight of the children attended Oriya‐medium schools where they received literacy instruction in Oriya from grade 1 and learned English from grade 2. Fifty‐one children attended English‐medium schools where they received literacy instruction in English from grade 1 and in Oriya from grade 2. The results showed that phonological awareness in Oriya contributed significantly to reading Oriya and English words and pseudo‐words for the children in the Oriya‐medium schools. However, it only contributed to Oriya pseudo‐word reading and English word reading for children in the English‐medium schools. Phonological awareness in English contributed to English word and pseudo‐word reading for both groups. Further analyses investigated the contribution of awareness of large phonological units (syllable, onsets and rimes) and small phonological units (phonemes) to reading in each language. The data suggest that cross‐language transfer and facilitation of phonological awareness to word reading is not symmetrical across languages and may depend both on the characteristics of the different orthographies of the languages being learned and whether the first literacy language is also the first spoken language.

Do readers with autism make bridging inferences from world knowledge?

Individuals with autism frequently show impairments in text reading comprehension. This often is attributed to poor ability to draw inferences during reading and to inadequate access to relevant knowledge. The current study tested this hypothesis by measuring the time taken to read the same question, relating to either physical or social world knowledge, when it was either relevant or irrelevant to the bridging inference evoked by a preceding two-sentence vignette. In the study, 16 normally developing adolescents and 16 adolescents with autism were matched on word reading accuracy, chronological age, and vocabulary but differed significantly in text comprehension. A strong priming effect was found, robust over participants and over items; participants read those questions that were relevant to the inference evoked by the vignette faster than they read those questions that were irrelevant, and no interaction with group membership or type of knowledge was found. This indicates that readers with autism, just like controls, were activating appropriate world knowledge primed by implicit inferences while reading the vignettes. Thus, the comprehension problems in these readers cannot be attributed to an inability to make implicit inferences or to draw on relevant world knowledge. Instead, we suggest that these problems must be sought at a higher level of text processing.

Assessment matters: Issues in the measurement of reading comprehension

The Neale Analysis of Reading Ability (NARA; Neale, 1997) is a widely used assessment of reading comprehension and word reading accuracy. Spooner, Baddeley, and Gathercole (2004) questioned the suitability of the NARA for identifying children with specific reading comprehension deficits. Aims and methods. An evaluation of the NARA measurement of word reading and reading comprehension level was undertaken in relation to models of reading ability. Appropriate control measures were considered. The strengths and weaknesses of different forms of reading comprehension were also evaluated. Previous research into reading comprehension difficulties using the NARA has adopted satisfactory control measures in relation to word reading ability. There are limitations associated with all the considered forms of reading comprehension assessment. If administered and interpreted appropriately, the NARA is an effective instrument for researchers and practitioners who need to assess both word reading accuracy and reading comprehension and to identify children with a dissociation between these two aspects of reading.

Profiles of children with specific reading comprehension difficulties

Children with fluent and accurate word reading in the presence of poor text comprehension are impaired on a wide range of reading-related tasks. This study investigated the consistency of skill impairment in a sample of poor comprehenders to identify any fundamental skill weakness that (i) might be associated with poor text comprehension, and (ii) might lead to depressed reading development. An additional aim was to determine whether reading comprehension difficulties are associated with more general educational difficulties. Twenty-three poor comprehenders and 23 good comprehenders with age-appropriate word reading accuracy were assessed when aged 8 years. Concurrent reading and language performance and reading, educational attainment and reasoning skills 3 years later are reported. The following skills were assessed when aged 8 years: word reading, text comprehension, vocabulary, syntax, cognitive ability, working memory, comprehension subskills. Listening comprehension, SAT scores and reasoning scores at 11 years are also reported. There was no evidence for any fundamental skill weaknesses in the population of poor comprehenders at Time 1. However, poor vocabulary skills led to impaired growth in word reading ability and poor general cognitive ability led to impaired growth in comprehension. Poor comprehenders obtained lower SAT scores than did the good comprehenders at 11 years. These findings indicate that a single underlying source of poor comprehension is unlikely. Poor comprehenders are at risk of generally poor educational attainment, although weak verbal or cognitive skills appear to affect the reading development of poor comprehenders in different ways.

The role of prosodic sensitivity in children's reading development

While the critical importance of phonological awareness (segmental phonology) to reading ability is well established, the potential role of prosody (suprasegmental phonology) in reading development has only recently been explored. This study examined the relationship between children's prosodic skills and reading ability. Hierarchical multiple regression analyses examined the unique contribution of word‐level and phrase‐level prosodic skills to the prediction of three concurrent measures of reading ability in 81 fourth‐grade children (mean age 9.3 years). After controlling for phonological awareness and general rhythmic sensitivity, children's prosodic skills predicted unique variation in word‐reading accuracy and in reading comprehension. Phrase‐level prosodic skills, assessed by means of a reiterative speech task, predicted unique variance in reading comprehension, after controlling for word reading accuracy, phonological awareness and general rhythmic sensitivity. These results add to the growing body of evidence of the importance of prosodic skills in reading development.

Spelling in Adults: The Combined Influences of Language Skills and Reading Experience

One hundred and twelve university students completed 7 tests assessing word-reading accuracy, print exposure, phonological sensitivity, phonological coding and knowledge of English morphology as predictors of spelling accuracy. Together the tests accounted for 71% of the variance in spelling, with phonological skills and morphological knowledge emerging as strong predictors of spelling accuracy for words with both regular and irregular sound-spelling correspondences. The pattern of relationships was consistent with a model in which, as a function of the learning opportunities that are provided by reading experience, phonological skills promote the learning of individual word orthographies and structural relationships among words.

Teacher-Education Students' Reading Abilities and their Knowledge about Word Structure

This study focused on teacher-education students taking a special-education language-arts course in which information about English word structure was taught. The relationship between students' component reading-related abilities and their performance on three measures of word-structure knowledge, before and after course instruction about word structure, was examined. Students' word reading accuracy and spelling ability, but not their general language abilities or reading speed, influenced their acquisition of word-structure knowledge. Specific patterns of results varied by word-structure task and by time (pre-vs. posttest); however, even students with strong component reading abilities performed at fairly low levels on the word-structure knowledge tasks at pretest, and course instruction influenced students' knowledge acquisition as much as or more than their component abilities did. Findings support the need to provide word-structure information in teacher preparation and suggest that it may sometimes be useful to assess different types of knowledge separately.

Unlocking the Nature of the Phonological–Deep Dyslexia Continuum: The Keys to Reading Aloud Are in Phonology and Semantics

Abstract It has been argued that normal reading and acquired dyslexias reflect the role of three underlying primary systems (phonology, semantics, and vision) rather than neural mechanisms dedicated to reading. This proposal is potentially consistent with the suggestion that phonological and deep dyslexia represent variants of a single reading disorder rather than two separate entities. The current study explored this possibility, the nature of any continuum between the disorders, and the possible underlying bases of it. A case series of patients were given an assessment battery to test for the characteristics of phonological and deep dyslexia. The status of their underlying phonological and semantic systems was also investigated. The majority of participants exhibited many of the symptoms associated with deep dyslexia whether or not they made semantic errors. Despite wide variation in word and nonword reading accuracy, there was considerable symptom overlap across the cohort and, thus, no sensible dividing line to separate the participants into distinct groups. The patient data indicated that the deep-phonological continuum might best be characterized according to the severity of the individual's reading impairment rather than in terms of a strict symptom succession. Assessments of phonological and semantic impairments suggested that the integrity of these primary systems underpinned the patients' reading performance. This proposal was supported by eliciting the symptoms of deep-phonological dyslexia in nonreading tasks.

Associated Reading Skills in Children with a History of Specific Language Impairment (SLI)

A large cohort of 200 eleven-year-old children with Specific Language Impairment (SLI) were assessed on basic reading accuracy and on reading comprehension as well as language tasks. Reading skills were examined descriptively and in relation to early language and literacy factors. Using stepwise regression analyses in which age and nonverbal IQ were controlled for, it was found that a single word reading measure taken at 7 years was unsurprisingly a strong predictor of the two different types of reading ability. However, even with this measure included, a receptive syntax task (TROG) entered when reading accuracy score was the DV. Furthermore, a test of expressive syntax/narrative and a receptive syntax task completed at 7 years entered into the model for word reading accuracy. When early reading accuracy was excluded from the analyses, early phonological skills also entered as a predictor of both reading accuracy and comprehension at 11 years. The group of children with a history of SLI were then divided into those with no literacy difficulties at 11 and those with some persisting literacy impairment. Using stepwise logistic regression, and again controlling for IQ and age, 7 years receptive syntax score (but not tests of phonology, expressive vocabulary or expressive syntax/narrative) entered as a positive predictor of membership of the ‘no literacy problems’ group regardless of whether early reading accuracy was controlled for in step one. The findings are discussed in relation to the overlap of SLI and dyslexia and the long term sequelae of language impairment.

Parsimonious Reading Models: Identifying Teachable Subskills

Parsimonious models of word recognition and reading comprehension were validated in a sample of third-grade readers. Word recognition was modeled as phonological awareness, decoding skill, and word processing rate. This model demonstrated the importance of unitization of letter clusters for efficient word reading. A curvilinear relation between word-processing rate and word recognition was also shown, and is interpreted as evidence that word-processing speed in excess of the rate necessary for adequate processing is not predictive of more accurate word reading. Reading comprehension was shown to be an additive model consisting of decoding and listening-comprehension skills. Results of the reading-comprehension model are consistent with the findings of Dreyer and Katz (1992) and Tiu, Thompson, and Lewis (2003). The word-recognition and reading-comprehension models demonstrate that the attainment of complex reading skills are associated with the development of expertise in more basic subskills of reading. These subskills can be taught to students by teachers who understand the complexities of the reading process.
