Book Description
This study examined the relationships between and among: (a) Processing Speed (PS) Cluster and Rapid Automatized Naming (RAN) Total to reading ability; (b) measures of RAN and PS to irregular word, non-word, and word reading; and (c) the relationships among irregular word, non-word, and word reading. The word reading measures were predicted by using multiple cognitive abilities including Phonological Awareness (PA), RAN, PS, and Working Memory (WM). Sixty participants, 39 students who were average readers and 21 students with reading difficulties in Grades 1, 2, 3, and 4 were recruited. Correlational designs testing predictive relationships were used to conduct this study. The results indicated that the PS Cluster had the strongest correlation with irregular word reading, whereas the RAN Total had the strongest correlation with both word reading and non-word reading ability. Reading performance was best predicted by RAN-Letters. In addition, the Woodcock-Johnson III Visual Matching test had the strongest predictive power of reading ability among all of the PS measures. High correlations were found among the reading variables within normally distributed data, whereas there was no significant correlation between irregular and nonword reading within the group of students with Reading Difficulties. These findings provide support for the dual-route theory. Among the 21 students with RD, 10 students presented problems in both non-word reading and irregular word reading; 9 students presented problems just in non-word reading; and 2 students presented problems just in irregular word reading. A model consisting of RAN, PA, and PS, as included in the study measures, provided the most powerful prediction of all reading skills. These findings also lend more support to the double-deficit model and indicate that PA and naming speed problems contribute independently to variance in reading. This study provides direction for the assessment of specific reading disability and the cognitive underpinnings of this disorder. These findings support the need to assess PA, RAN, and PS, as well as various types of word reading skills, when making a reading disability diagnosis. Further research may cross validate the results of this study, or add other aspects of reading (eg., reading fluency or comprehension) to this line of research.

Book Description
This book explored the cognitive correlates that best predicted irregular word, non-word, and word reading, and reading performance of typical and poor readers. The findings indicated that processing speed had the strongest correlation with irregular word reading, whereas rapid automatized naming (RAN) had the strongest correlations with word reading and non-word reading. As with previous research RAN letters was the best predictor of reading skills. The best model for predicting reading was based on a combined measure of phonological awareness (PA) and RAN letters. An interesting finding was that the correlation between irregular and non-word reading was significant for students with typical reading, but insignificant for the poor readers. These findings provide support for both the dual-route and double-deficit theory of dyslexia that ascribes independent contributions of PA and RAN to the development of reading skills. This book presents information that will help school psychologists, neuropsycholoists, educational diagnostician, special education teachers, as well as general education teachers, to recognize, assess, and provide effective treatment programs for dyslexia.

Book Description
Psychological assessment has always paralleled the growth of psychology and its specialties, and it is not an overstatement to say that measurement and assessment are the cornerstones of psychology, providing the tools and techniques for gathering information to inform our understanding of human behavior. However, the continued growth and new developments in the assessment literature requires an ongoing examination of the principles and practices of central importance to psychological assessment. The Oxford Handbook of Child Psychological Assessment covers all areas of child and adolescent assessment. Leaders in the field summarize and synthesize state-of-the-science assessment theories, techniques, and applications. Placing an emphasis on clinical and psychoeducational assessment issues, chapters explore issues related to the foundations, models, special topics, and practice of psychological assessment. Appropriate as a desk reference or a cover-to-cover read, this comprehensive volume surveys fundamental principles of child assessment, including ability, achievement, behavior, and personality; covers the role of theory and measurement in psychological assessment; and presents new methods and data.

Book Description
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.

Book Description
Reading involves decoding and comprehension components and, to become efficient, it requires a large number of cognitive and linguistic processes. Among those, the phonological awareness, the alphabetic principle, the decoding, the fluency, the lexical development and the text comprehension development. The reading comprehension is strongly related with the development of vocabulary, oral language, linguistic skills, memory skills and ability to make inferences, and the world experiences of each individual. These processes become important only when the professional needs to deal with students presenting difficulties in learning how to read. The difficulty using the knowledge of conversion rules between grapheme and phoneme to the word reading construction characterizes the dyslexia, which is a specific learning disorder with a neurological source. These difficulties presented by students with dyslexia interfere in their learning process impairing the learning development. Knowing and following the reading development and its processes, as well as obtaining the punctuation of fluency abilities and students comprehension allow us to understand what happens when the student presents difficulties to read. This could help in the identification of learning disabilities and in the development of intervention programs.
