Altering the brain circuits for reading through intervention: A magnetic source imaging study.

Intervention-related changes in spatiotemporal profiles of regional brain activation were examined by whole-head magnetoencephalography in 15 children with severe reading difficulties who had failed to show adequate progress to quality reading instruction during Grade 1. Intensive intervention initially focused on phonological decoding skills (for 8 weeks) and, during the subsequent 8 weeks, on rapid word recognition ability. Clinically significant improvement in reading skills was noted in 8 children who showed "normalizing" changes in their spatiotemporal profiles of regional brain activity (increased duration of activity in the left temporoparietal region and a shift in the relative timing of activity in temporoparietal and inferior frontal regions). Seven children who demonstrated "compensatory" changes in brain activity (increased duration of activity in the right temporoparietal region and frontal areas, bilaterally) did not show adequate response to intervention. Nonimpaired readers did not show systematic changes in brain activity across visits. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The Development of Reading in Children Who Speak English as a Second Language.

Patterns of reading development were examined in native English-speaking (L1) children and children who spoke English as a second language (ESL). Participants were 978 (790 L1 speakers and 188 ESL speakers) Grade 2 children involved in a longitudinal study that began in kindergarten. In kindergarten and Grade 2, participants completed standardized and experimental measures including reading, spelling, phonological processing, and memory. All children received phonological awareness instruction in kindergarten and phonics instruction in Grade 1. By the end of Grade 2, the ESL speakers' reading skills were comparable to those of L1 speakers, and ESL speakers even outperformed L1 speakers on several measures. The findings demonstrate that a model of early identification and intervention for children at risk is beneficial for ESL speakers and also suggest that the effects of bilingualism on the acquisition of early reading skills are not negative and may be positive.

Development of word reading fluency and spelling in a consistent orthography: An 8-year follow-up.

In a longitudinal study, development of word reading fluency and spelling were followed for almost 8 years. In a group of 115 students (65 girls, 50 boys) acquiring the phonologically transparent German orthography, prediction measures (letter knowledge, phonological short-term memory, phonological awareness, rapid automatized naming, and nonverbal IQ) were assessed at the beginning of Grade 1; reading fluency and spelling were tested at the end of Grade 1 as well as in Grades 4 and 8. Reading accuracy was close to ceiling in all reading assessments, such that reading fluency was not heavily influenced by differences in reading accuracy. High stability was observed for word reading fluency development. Of the dysfluent readers in Grade 1, 70% were still poor readers in Grade 8. For spelling, children who at the end of Grade 1 still had problems translating spoken words into phonologically plausible letter sequences developed problems with orthographic spelling later on. The strongest specific predictors were rapid automatized naming for reading fluency and phonological awareness for spelling. Word recognition speed was a relevant and highly stable indicator of reading skills and the only indicator that discriminated reading skill levels in consistent orthographies. Its long-term development was more strongly influenced by early naming speed than by phonological awareness. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Phonological processing skills and the Reading Recovery Program.

Sought to determine whether the Reading Recovery Program would be more effective if systematic instruction in phonological recoding skills were incorporated into the program. First-grade at-risk readers were divided into 3 matched groups of 32 children each; a modified Reading Recovery group, a standard Reading Recovery group, and a standard intervention group. The children in the modified Reading Recovery group received explicit code instruction involving phonograms. Results indicated that, although both Reading Recovery groups achieved levels of reading performance required for discontinuation of the program, the modified Reading Recovery group reached these levels of performance much more quickly. Results further indicated that the children selected for Reading Recovery were particularly deficient in phonological processing skills and that their progress in the program was strongly related to the development of these skills.

Predicting Improvement After First-Grade Reading Difficulties: The Effects of Oral Language, Emergent Literacy, and Behavior Skills.

This study investigated the role of early literacy and behavioral skills in predicting the improvement of children who have experienced reading difficulties in 1st grade. The progress of 146 low-income children whose reading scores in 1st grade were below the 30th percentile was examined to determine (a) how the poorest readers in 1st grade progressed in reading achievement through 4th grade and (b) which emergent literacy and behavioral skills measured in kindergarten predicted differential 4th grade outcomes. Results indicated that the divergence between children who improved and those who did not was established by the end of 2nd grade. Further, individual linguistic skills and behavioral attributes measured in kindergarten contributed substantively to this difference. Implications for intervention timing and educational policy are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The Odds of Becoming a Precocious Reader of Finnish.

The authors examined the developmental relations between language acquisition and emergence of reading prior to formal literacy instruction. Sixty-one Finnish-speaking children were followed up once a year from infancy to school start (1 year 0 months-7 years 3 months). Before entering first grade, 43% of the children were classified as emergent readers and 30% as precocious readers. The readers had displayed more rapid vocabulary, inflectional, and metaphonological development than their agemates. Increased awareness of sound patterns emerged well before word reading. However, the striking growth spurt in phonemic awareness can be regarded more as a consequence of than a precursor to reading. The findings suggest that early mastery of words and word inflections increases the likelihood of becoming aware of sound patterns in words.

Effective Reading Comprehension Instruction: Examining Child x Instruction Interactions.

This study examined the effect of 3rd-grade language arts instruction on growth in children's reading comprehension skills and the degree to which the impact of instruction depended on the language and reading skills children brought to the classroom. Classrooms were observed in the fall, winter, and spring, and language arts activities were coded using multiple dimensions of instruction. Overall, the effect of instruction depended on children's fall reading comprehension scores. Children with average to low fall reading comprehension scores achieved greater growth in classrooms with more time spent on teacher-managed reading comprehension instructional activities but demonstrated less growth in classrooms with more time spent on child-managed reading comprehension activities. Research and classroom instruction implications are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Early identification of reading difficulties using heterogeneous developmental trajectories.

Serious conceptual and procedural problems associated with current diagnostic methods call for alternative approaches to assessing and diagnosing students with reading problems. This study presents a new analytic model to improve the classification and prediction of children's reading development. Growth mixture modeling was used to identify the presence of 10 different heterogeneous developmental patterns. In all, 411 children in kindergarten through Grade 2 from 3 elementary schools in Texas were administered measures of phonological awareness, word recognition, and rapid naming skills 4 times a year. The mean ages were 5.8 years (SD = 0.35) for the kindergartners, 6.9 years (SD = 0.39) for Grade 1, and 8.0 years (SD = 0.43) for Grade 2; the percentage of boys was 50%. The results indicate that precursor reading skills such as phonological awareness and rapid naming are highly predictive of word reading (word recognition) and that developmental profiles formed in kindergarten are directly associated with development in Grades 1 and 2. Students identified as having reading-related difficulties in kindergarten exhibited slower development of word recognition skills in subsequent years of the study.

Effects of Intensive Reading Remediation for Second and Third Graders and a 1-Year Follow-Up.

Second- and 3rd-grade children with poor word-level skills were randomly assigned to 8 months of explicit instruction emphasizing the phonologic and orthographic connections in words and text-based reading or to remedial reading programs provided by the schools. At posttest, treatment children showed significantly greater gains than control children in real word and nonword reading, reading rate, passage reading, and spelling, and largely maintained gains at a 1-year follow-up. Growth curve analyses indicated significant differences in growth rate during the treatment year, but not during the follow-up year. Results indicate that research-based practices can significantly improve reading and spelling outcomes for children in remedial programs.

Increasing Reading Comprehension and Engagement Through Concept-Oriented Reading Instruction.

Based on an engagement perspective of reading development, we investigated the extent to which an instructional framework of combining motivation support and strategy instruction (Concept-Oriented Reading Instruction--CORI) influenced reading outcomes for third-grade children. In CORI, five motivational practices were integrated with six cognitive strategies for reading comprehension. In the first study, we compared this framework to an instructional framework emphasizing Strategy Instruction (SI), but not including motivation support. In the second study, we compared CORI to SI and to a traditional instruction group (TI), and used additional measures of major constructs. In both studies, class-level analyses showed that students in CORI classrooms were higher than SI and/or TI students on measures of reading comprehension, reading motivation, and reading strategies.

Brain mechanisms for reading and language processing in spina bifida meningomyelocele: A combined magnetic source- and structural magnetic resonance imaging study.

Objective: The development of the ability to process spoken and written language depends upon a network of left hemisphere temporal, parietal, and frontal regions. The present study explored features of brain organization in children with spina bifida meningomyelocele (SBM) and shunted hydrocephalus, who commonly present with precocious development of word reading skills and preservation of vocabulary and grammar skills. Method: Eight children with SBM were compared with 15 IQ and reading-level matched, typically developing controls on MRI-based morphometric and Magnetic Source Imaging-derived neurophysiological profiles. Results: Children with SBM showed reduced magnetic activity in left inferior parietal regions during spoken word recognition and pseudoword reading tasks. We also noted reduced surface area/volume in inferior parietal and posterior temporal regions in SBM and increased gray matter volumes in left middle frontal regions and gyral complexity in left posterior temporal and inferior parietal regions. Conclusions: A complex pattern of changes in cortical morphology and activation may serve as evidence for structural and functional brain reorganization ensuring preservation of language and decoding abilities in children with SBM.

Morphological awareness: A key to understanding poor reading comprehension in English.

This longitudinal study examined the performance of poor comprehenders on several reading-related abilities in the late elementary school years. We identified 3 groups of readers in Grade 5 who were matched on word reading accuracy and speed, nonverbal cognitive ability, and age: unexpected poor comprehenders, expected average comprehenders, and unexpected good comprehenders. We compared these groups in Grade 5 and, retrospectively, in Grade 3. The 3 groups performed similarly on phonological awareness, naming speed, and orthographic processing tasks but differed in morphological awareness, even when vocabulary was controlled statistically. Unexpected poor comprehenders performed more poorly than expected average comprehenders in morphological derivation at Grade 5 but not in Grade 3; in contrast, expected average comprehenders performed more poorly than unexpected good comprehenders at Grade 3, but these groups did not differ in Grade 5. Our findings suggest that poor morphological awareness contributes to reading comprehension difficulties and that children with different reading comprehension profiles may learn morphology at different rates.

Assessment and Early Instruction of Preschool Children at Risk for Reading Disability.

Preschool children at familial risk for reading disability were assessed on cognitive and linguistic variables and compared with preschoolers without familial risk. Risk children displayed performance profiles resembling those of older children with reading disability. Each group received intensive instruction in phonemic awareness and structured book reading. Instructed risk children made somewhat smaller gains than the nonrisk and required more teaching sessions to reach criterion. Rhyme and phoneme awareness predicted instruction outcome levels, and vocabulary and verbal short-term memory predicted number of teaching sessions to criterion. In kindergarten, the nonrisk group outperformed the risk group on reading and spelling, although the risk group reached grade-appropriate levels. At-risk children can be helped by appropriate preschool instruction, but they require more sustained teaching than nonrisk preschoolers.

Functional disruption of the brain mechanism for reading: Effects of comorbidity and task difficulty among children with developmental learning problems.

Objective: The study investigated the relative degree and timing of cortical activation associated with phonological decoding in poor readers. Method: Regional brain activity was assessed during performance of a pseudoword reading task and a less demanding, letter-sound naming task by three groups of students: children who experienced reading difficulties without attention problems (N = 50, RD) and nonreading impaired (NI) readers either with (N = 20) or without attention-deficit/hyperactivity disorder (ADHD; N = 50). Recordings were obtained with a whole-head neuromagnetometer, and activation profiles were computed through a minimum norm algorithm. Results: Children with RD showed decreased amplitude of neurophysiological activity in the superior temporal gyrus, bilaterally, and in the left supramarginal and angular gyri during late stages of decoding, compared to typical readers. These effects were restricted to the more demanding pseudoword reading task. No differences were found in degree of activity between NI and ADHD students. Regression analyses provided further support for the crucial role of left hemisphere temporoparietal cortices and the fusiform gyrus for basic reading skills. Conclusions: Results were in agreement with fMRI findings and replicate previous MEG findings with a larger sample, a higher density neuromagnetometer, an overt pseudoword reading task, and a distributed current source-modeling method.

Effects of preschool phoneme identity training after six years: Outcome level distinguished from rate of response.

Grade 5 children who had been trained in phoneme identity 6 years earlier in preschool were superior to untrained controls on irregular word reading; on a composite list of nonwords, regular words, and irregular words; and on a separate nonword test. Some of the trained children had become poor readers by Grade 5. These poor readers had made slow progress in achieving phonemic awareness in preschool even though they were eventually successful. In general, the rate at which trained children achieved phonemic awareness in preschool accounted for variance in school literacy progress in addition to that accounted for by the actual level of phonemic awareness achieved. Preschool instruction in phonemic structure had modest but detectable effects on later reading skill, but children who were slow to achieve phonemic awareness tended to be hampered in later reading growth.

The intriguing role of spanish language vocabulary knowledge in predicting English reading comprehension.

This study explored a holistic model of English reading comprehension among a sample of 135 Spanish-English bilingual Latina and Latino 4th-grade students This model took into account Spanish language reading skills and language of initial literacy instruction. Controlling for language of instruction, English decoding skill, and English oral language proficiency, the authors explored the effects of Spanish language alphabetic knowledge, fluency, vocabulary knowledge, and listening comprehension on English reading comprehension. Results revealed a significant main effect for Spanish vocabulary knowledge and an interaction between Spanish vocabulary and English fluency, such that faster English readers benefited more from Spanish vocabulary knowledge than their less fluent counterparts. This study demonstrates the existence of literary skills transfer from the 1st to the 2nd language, as well as limits on such transfer.

Early predictors of biliteracy development in children in French immersion: A 4-year longitudinal study.

English language predictors of English and French reading development were investigated in a group of 140 children who were enrolled in French immersion programs. Children were first tested in kindergarten, and their reading achievement was tested yearly in both English and French from Grades 1 to 3, with word-level and passage-level measures that assessed accuracy as well as fluency. Hierarchical linear modeling was used to examine which English variables predicted Grade 3 outcomes and growth rates in English and French, and to determine the set of predictors that accounted for the most variance in outcomes and growth rates in English and French reading. The variables that predicted English reading development were consistent with studies of monolingual English children, even though participants were concurrently learning to read in French. Our findings provide evidence that at least some of the skills that play a role in learning to read are general cognitive and linguistic skills that transfer across languages. Phonological awareness, letter-sound knowledge, rapid automatized naming, and grammatical ability in English were able to predict reading ability in French. In contrast, English receptive vocabulary was a language-specific predictor. These findings demonstrate that first-language measures can be useful in the early identification of children at risk for difficulty in learning to read in a second language.

Becoming a Fluent Reader: Reading Skill and Prosodic Features in the Oral Reading of Young Readers.

Prosodic reading, or reading with expression, is considered one of the hallmarks of fluent reading. The major purpose of the study was to learn how reading prosody is related to decoding and reading comprehension skills. Suprasegmental features of oral reading were measured in 2nd- and 3rd-grade children (N = 123) and 24 adults. Reading comprehension and word decoding skills were assessed. Children with faster decoding speed made shorter and less variable intersentential pauses, shorter intrasentential pauses, larger sentence-final fundamental frequency (F?) declinations, and better matched the adult prosodic F? profile. Two structural equation models found evidence of a relationship between decoding speed and reading prosody as well as decoding speed and comprehension. There was only minimal evidence that prosodic reading was an important mediator of reading comprehension skill. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Reading comprehension: Developmental processes, individual differences, and interventions.

Research on the typical development of reading comprehension, individual differences in comprehension, and reading comprehension interventions is less common than research on word reading. The authors present an overview of research on the development of reading comprehension skills and sources of individual differences in comprehension with reference to cognitive models of comprehension. Methodological issues particular to developmental and individual difference research on comprehension are also described. The article ends with a selective review of research programmes that illustrate effective comprehension interventions for typically developing children and for children who struggle to understand what they read.

Development of the interplay between automatic processes and cognitive resources in reading.

An account was tested of the development of the interplay between automatic processes and cognitive resources in reading. According to compensatory-encoding theory, with advancing skill, readers increasingly keep automatic processes from faltering and provide timely, accurate data to working memory by pausing, looking back, rereading, and compensating in other ways when automatic processes fail. Reading skill profiles (e.g., word naming, semantic access, working memory capacity) were obtained from 71 third graders, 68 fifth graders, and 72 seventh graders from a university lab school or a public school (ages 7 to 15; 146 Caucasians, 61 African Americans, 2 Native Americans, 2 Latino Americans). Children participated in an unrestricted reading task (no time or performance pressure) and were randomly assigned to 1 of 2 levels of 3 experimental manipulations of restriction on reading: time pressure or no pressure, constant reading rate or variable reading rate, read silently or read aloud. Regression analyses revealed that developmental level and restriction moderated the reading skill level-comprehension relationship, and restriction lowered comprehension when it overwhelmed skills, especially for younger readers. Verbally inefficient readers compensated most often, and older readers compensated most efficiently. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
