This book was released on 2016-06-24 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the mechanisms responsible for developmental dyslexia (DD) is a key challenge for researchers. A large literature, mostly concerned with learning to read in opaque orthographies, emphasizes phono-logical interpretations of the disturbance. Other approaches focused on the visual-per-ceptual aspects of orthographic coding. Recently, this perspective was supported by imaging data showing that individuals with DD have hypo-activation in occipito-temporal areas (a finding common to both transpar-ent and opaque orthographies). Nevertheless, it is difficult to infer causal relationships from activation data. Accommodating these findings within the cognitive architecture of reading processes is still an open issue. This is a general problem, which is present in much of the literature. For example, several studies investigating the perceptual and cognitive abilities that distinguish groups of children with and without DD failed to provide explicit links with the reading process. Thus, several areas of investigation (e.g., acoustic deficits or magnocellular deficiencies) have been plagued by replication failures. Furthermore, much research has neglected the possible contribution of comorbid symptoms. By contrast, it is now well established that developmental disorders present a large spectrum of homotopic and heterotopic co-morbidities that make causal interpretations problematic. This has led to the idea that the etiology of learning difficulties is multifactorial, thus challenging the traditional models of DD. Recent genetic studies provide information on the multiple risk factors that contribute to the genesis of the disturbance. Another critical issue in DD is that much of the research has been conducted in English-speaking individuals. However, English is a highly irregular orthography and doubts have been raised on the appropriateness of automatically extending interpretations based on English to other more regular orthographies. By contrast, important information can be gotten from systematic comparisons across languages. Thus, the distinction between regular and irregular orthographies is another potentially fruitful area of investigation. Overall, in spite of much research current interpretations seem unable to integrate all available findings. Some proposals focus on the cognitive description of the reading profile and explicitly ignore the distal causes of the disturbance. Others propose visual, acoustic or phonological mech-anisms but fail to link them to the pattern of reading impairment present in different children. The present Research Topic brings together studies based on different methodological approaches (i.e., behavioural studies examining cognitive and psycholinguistic factors, eye movement inves-tigations, biological markers, neuroimaging and genetic studies), involving dyslexic groups with and without comorbid symptoms, and in different orthographies (transparent and opaque) to identify the mechanisms underlying DD. The RT does not focus on a single model or theory of dyslexia but rather brings together different approaches and ideas which we feel are fruitful for a deeper understanding developmental dyslexia.
Download or read book Foundations of Reading Acquisition and Dyslexia written by Benita A. Blachman and published by Routledge. This book was released on 2013-03-07 with total page 541 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chapters in this volume are based on presentations made at a recent conference on cognitive and linguistic foundations of reading acquisition. The researchers who participated have all made contributions to the theoretical and empirical understanding of how children learn to read. They were asked to address not only what they have learned from their research, but also to discuss unsolved problems. This dialogue prompted numerous questions of both a theoretical and applied nature, generated heated debate, and fueled optimism about the important gains that have been made in the scientific understanding of the reading process, especially of the critical role played by phonological abilities.

Available in PDF, EPUB and Kindle. Book excerpt: Although the dominant view of dyslexia is that it is caused by linguistic/phonological weakness, recent research within neuroscience has shown that it is associated with visual processing problems as well. This book brings together research from neurology, neuroscience, and the vision sciences to present a cutting edge review of this topic.
Download or read book Fluency in Reading written by Zvia Breznitz and published by Routledge. This book was released on 2006-08-15 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book to examine in-depth the crucial role of the speed of information processing in the brain in determining reading fluency in both normal and dyslexic readers. Part I explains fluency in reading from both traditional and modern perspectives. Fluency has historically been viewed as the outcome of other reading-related factors and has often been seen as a convenient measure of reading skills. This book, however, argues that fluency has a strong impact on other aspects of reading and plays a central role in the entire reading process. Part II deals with the determinants of reading fluency. Chief among these is the speed of information processing in the brain. Using both behavioral and electrophysiological evidence, the book systematically examines the features of processing speed in the various brain systems involved in reading: visual-orthographic, auditory-phonological, and semantic and shows how speed of processing affects fluency in reading. Part III deals with the complex issues of cross-modal integration and specifically with the need for effective synchronization of the brain processes involved in reading. It puts forward the Synchronization Hypothesis and discusses the role of the Asynchrony Phenomenon as a major factor in dyslexia. Finally, it summarizes research on manipulating reading rate by means of the Acceleration method, providing evidence for a possible intervention aimed at reducing Asynchrony. Key features of this outstanding new book include: *Expanded View of Fluency. Reading fluency is seen as both a dependent and an independent Variable. Currently available books focus on reading rate solely as the outcome of other factors whereas this volume stresses that it is both an outcome and a cause. *Information Processing Focus. Fluency itself is determined to a large extent by a more general factor, namely, speed of processing in the brain. The book presents wide-ranging evidence for individual differences in speed of processing across many subpopulations. *Brain Synchronization Focus. The book posits a new theory arguing that effective reading requires synchronization of the different brain systems: visual orthographic, auditory-phonological, and semantic. *Research-Based Interventions. Interventions to enhance fluency and, thereby, reading skills in general are presented in detail. *Author Expertise. Zvia Breznitz is Head of the Department of Learning Disabilities and Director of the Laboratory for Neurocognitive Research at Haifa University in Israel, where she has been researching this topic for over a decade. This book is appropriate for researchers and advanced students in reading, dyslexia, learning disabilities, cognitive psychology, and neuropsychology.
Download or read book Voices from the Classroom A Celebration of Learning written by Vana Chiou and published by Waxmann Verlag. This book was released on 2021 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: Voices from the Classroom illustrates that teachers have a leading voice in the policies that impact their students and the profession of teaching. The aim is to provide a rich and broad view of the impact of inquiry in the classrooms, from primary to higher education, and to provide a window into the perspective of teachers. Voices from the Classroom allows us to advance this mission by identifying and then turning educators' ideas into action. The publication includes chapters on issues ranging from dyslexic students' geospatial abilities to teachers' differential behaviours related, student characteristics and the experiences of refugees with bullying in the educational space. All the contributions published in this book emerged from real classrooms: our teachers and researchers conducted their research by drawing on their experience as educators. We believe that these insights into everyday classrooms, and the issues affecting them, are crucial to making teaching and learning better. We hope they can help drive real, positive change for students and teachers.
Download or read book Reading and Dyslexia written by Thomas Lachmann and published by Springer. This book was released on 2018-07-28 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume a group of well-known experts of the field cover topics ranging from basic visual and auditory information processing to higher order cognition in reading and dyslexia, from basic research to remediation approaches and from well-established theories to new hypotheses about reading acquisition and causes for its failure. Reading is one of the most intriguing feats human evolution ever came up with. There is no evolutionary basis for reading as such; reading is secondary to language and the result of a complex skill acquisition at the end of which almost all pre-existing cognitive functions are mobilized. With the right instruction and practice most people learn this skill smoothly. Some, however, have problems, despite same opportunities and general cognitive abilities. This developmental dyslexia results from a neuro developmental disorder leading to deficits in reading relevant information processing. But what deficits are these, and can they be trained?

Download or read book Reading Acquisition and Developmental Dyslexia written by Liliane Sprenger-Charolles and published by Psychology Press. This book was released on 2013-04-15 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most studies on reading have been conducted with English-speaking subjects. It is crucial to also examine studies conducted in different languages, in order to highlight which aspects of reading acquisition and dyslexia appear to be language-specific, and which are universal. Reading Acquisition and Developmental Dyslexia sheds new light on dyslexia and its relationship with reading acquisition, presenting two unique advancements in this area. Looking at studies conducted in different languages, the prerequisites of reading acquisition are examined, and the findings from studies of skilled adult readers are presented. The manifestations of developmental dyslexia and the main contemporary explanations for it are outlined, providing an in-depth, well researched discussion of the topic. The authors conclude by offering a new framework which could explain both reading acquisition and developmental dyslexia. A fascinating book offering a unique insight into the topic of dyslexia, it will be of great interest to students and lecturers in cognitive psychology, educational psychology, and psycholinguistics, as well as those with a more everyday involvement with the disorder such as speech and language therapists.

Available in PDF, EPUB and Kindle. Book excerpt: Even though I had been studying reading problems in children for a number of years as a means of understanding cognitive processes, I became deeply committed to the study of developmental dyslexia after my encounter with S. H. , a dyslexic college student. Until then, dyslexia to me remained an interesting phenomenon but somewhat removed from the mainstream of my research interests. The facts that, in spite of his superior IQ, S. H. could read no better than a child in the fifth grade and misspelled even common words such as was and here, however, took me by surprise and made me appreciate the intriguing and challenging nature of developmental dyslexia. This led to a series of studies of college students with reading disability, a group that is relatively unexplored. The general plan of these investigations was to study a small number of disabled readers at any given time, rather intensively. Even though this approach limits the generalizability of the research findings, it lays bare some of the most interesting facts about dyslexia which are obscured in large-scale statistical studies. These studies have now extended well over a decade and are still continuing. As soon as these studies were started, it became obvious that not all reading-disabled college students are alike and that disabled readers could be classified into three broad categories: those with poor decod ing skill, those with poor comprehension ability, and those with a combination of these two deficits.

Download or read book Oscillatory Temporal Sampling and Developmental Dyslexia Towards an Over Arching Theoretical Framework written by Usha Goswami and published by Frontiers Media SA. This book was released on 2015-04-01 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Children with developmental dyslexia fail to acquire efficient reading and spelling skills despite adequate tuition and an absence of overt sensory and/ or neural deficits. Learning to read and spell requires linguistic skills, auditory skills and visual skills. Oscillatory 'temporal sampling' theory links the development of sensory and linguistic processes. The auditory system 'samples' acoustic information at different temporal rates, which for speech processing suggests that temporal information encoded by delta, theta and gamma oscillations is bound together in the final speech percept. Temporal sampling theory proposed a possible deficit in dyslexia in auditory sampling of the speech signal at syllable-relevant rates (< 10 Hz, delta and theta). This would hypothetically affect prosodic development prior to reading and syllable-based parsing, which would affect efficient linguistic skills and consequently reading development across languages. The visual system also samples information in the visuo-spatial field. In theory atypical visual oscillatory sampling could therefore be related to some of the visual features of developmental dyslexia. In this special issue, we bring together visual and auditory sensory processing studies around the general theme of oscillatory temporal sampling. Contributors were encouraged to discuss their findings within a temporal sampling perspective. The resulting studies cover a wide range of sensory processes, with findings both supporting and contradicting the theory. It is also important to note that studies covered a wide range of languages, and that the behavioural manifestations of a sampling impairment may differ both with language and over the course of development. Nevertheless, it is encouraging to see such diverse findings considered within a single theoretical framework, even if at the same time, it is apparent that an over-arching theoretical framework encompassing both visual and auditory deficits in dyslexia is yet to be achieved.
