Summary
Early language and reading problems are common and therefore significant public health problems. They are disabling and have life-long implications for oral and written communication skills, social and emotional well-being, cognition, behaviour, academic achievement and employment. This study will address the following three problems: 1. To date no study has documented how language and reading problems develop from infancy (8 months) through to school age (7 years). 2.

They are disabling and have life-long implications for oral and written communication skills, social and emotional well-being, cognition, behaviour, academic achievement and employment. This study will address the following three problems: 1. To date no study has documented how language and reading problems develop from infancy (8 months) through to school age (7 years). 2. Little is known about risk factors, identified early in infancy and childhood, that can be reliably used to predict language and reading problems later in childhood. 3. The relationships between language difficulties and reading problems are poorly understood. Therefore, we currently have no satisfactory methods for reliably detecting which children at much younger ages are at risk of later language disorders or reading problems. Without this information it is impossible to develop effective prevention and early intervention programs. These programs are critical if we are to: a) Prevent language and reading problems from occurring, thereby reducing the prevalence of the problem b) Intervene early in childhood, thereby reducing in the longer term the burden and cost associated with language and reading problems. The proposed study builds on an existing substantial investment by the NHMRC in the Early Language in Victoria Study (ELVS). It will provide a world-first description of the evolution of language difficulties and reading problems from infancy through to school age within a single population cohort.Read moreRead less

Summary
With the advent of the human genome project, Australian researchers into serious childhood reading disorders are now in a position to make breakthroughs in understanding the complex linkages between genes and dyslexia. It is widely acknowledged that previous studies on the genetics of dyslexia have been limited by their failure to distinguish the different component processes in reading and the different patterns of dyslexia that they produce, and by being unable to look widely across the human ....With the advent of the human genome project, Australian researchers into serious childhood reading disorders are now in a position to make breakthroughs in understanding the complex linkages between genes and dyslexia. It is widely acknowledged that previous studies on the genetics of dyslexia have been limited by their failure to distinguish the different component processes in reading and the different patterns of dyslexia that they produce, and by being unable to look widely across the human genome. This new research addresses these two problems. Firstly, the researchers have developed a computational model of reading that identifies around a dozen basic mental processes which are recruited during skilled reading. This model provides the extremely precise phenotypes required for genetic research. Secondly, the researchers will take advantage of both very high density scans within known regions of interest on chromosomes 2,6, and 15, as well as a genome-wide scan of 400 markers small elements of DNA whose position within the genome is known, thus allowing researchers to narrow-down the location of new genes for reading. The research thus promises not only to refine our understanding of the basis for three previous genetic markers of dyslexia, but also to potentially uncover new genes related to specific elements of reading across the genome. The project pools the resources of the Macquarie Centre for Cognitive Science, the Australian Genome Research Facility, and The Garvan Institute and the researchers hope that the work will lead eventually to identifying the genes for dyslexia and to improved diagnosis and treatment of reading disorders in Australia.Read moreRead less
Functional Brain Age Measurement In Children And Adolescents

Summary
An important aspect of medicine is measuring the function of the human body. It is often advantageous to convert complex functional measures into simpler, intuitive measures such as 'age'. We can compare functional age to chronological age to diagnose disease. In this project, we will build an estimate of 'brain age' in children and adolescents using recordings of the electrical activity of the brain. We will test this 'brain age' as a diagnostic tool in several neurological disorders.

According to a recent DEST report a disturbingly high number of Australian school children are failing to meet a minimum acceptable standard in literacy . Failure to reach these standards is associated with poorer outcomes in mental health and socioeconomic status, greater representation among the prison population and with failure to achieve to true ability.

Failure to reach these standards is associated with poorer outcomes in mental health and socioeconomic status, greater representation among the prison population and with failure to achieve to true ability. Further, failure to correct these problems may well result in transmission of the problems associated with failed literacy into the next generation. Despite the obvious immense social and personal ramifications and cost, literacy instruction for adults continues to lack a theoretical and research based approach . It is plain that improving population literacy would have significant benefits and it is also plain that early detection, intervention and remediation is desirable. This project brings to bear on these important aims current expertise in the nature of reading, how children learn to read and why some have so much difficulty in doing so, and techniques for determining the neural substrates of the mechanisms involved in reading and learning to read. We will subdivide child readers on the basis of their ability to read words using the letter to sound route or dictionary look-up route. We will use magnetic resonance imaging and spectroscopy to examine which parts of the brain are disrupted and-or disconnected when ability to read in either of these two routes is poor. We will then remediate these poor readers using targetted remediation therapy and re-image them to see whether remediation has altered the way the brain reads.Read moreRead less
