Lexical retrieval and reading comprehension: Binding perceptual, lexical and conceptual information in on-line reading. Reading is a complex process that involves integrating sensory information extracted from text with stored memories about word meanings, syntactic structures and general knowledge. Most reading research has focused on the processing of isolated words, but normal reading requires integration processes that are not necessary to recognise single words. This research uses tasks req ....Lexical retrieval and reading comprehension: Binding perceptual, lexical and conceptual information in on-line reading. Reading is a complex process that involves integrating sensory information extracted from text with stored memories about word meanings, syntactic structures and general knowledge. Most reading research has focused on the processing of isolated words, but normal reading requires integration processes that are not necessary to recognise single words. This research uses tasks requiring sentence comprehension and measures of eye movements during reading to investigate how readers retrieve and combine information while reading to comprehend text. It will contribute to developing more comprehensive theories of normal reading that can inform methods of teaching reading and contribute to refinement of text recognition systems.Read moreRead less
Reconciling perceptual and cognitive accounts of dyslexia: The neural rate deficit hypothesis. The proposed research will form part of a co-ordinated program to understand the causes of dyslexia, a disorder that affects a large number of children and often persists into adulthood. It complements parallel efforts to elucidate the genetic basis of dyslexia, the heterogeneity and subtypes of dyslexia, and the developmental precursors to the disorder. This research will inform early intervention and ....Reconciling perceptual and cognitive accounts of dyslexia: The neural rate deficit hypothesis.

It complements parallel efforts to elucidate the genetic basis of dyslexia, the heterogeneity and subtypes of dyslexia, and the developmental precursors to the disorder. This research will inform early intervention and remediation efforts and will also assist in the understanding of the normal process of reading acquisition in children.Read moreRead less
Children's difficulties in learning to read: Causes and consequences of poor letter-sound knowledge. This research will identify the causes and treatments of reading impairment in children. This will help the Government counter the effects of poor reading instruction in Australian schools (see the National Inquiry into the Teaching of Literacy). The outcomes will reveal how struggling readers should be taught in classrooms, and which treatments should be covered by the Reading Assistance Voucher ....Children's difficulties in learning to read: Causes and consequences of poor letter-sound knowledge. This research will identify the causes and treatments of reading impairment in children. This will help the Government counter the effects of poor reading instruction in Australian schools (see the National Inquiry into the Teaching of Literacy). The outcomes will reveal how struggling readers should be taught in classrooms, and which treatments should be covered by the Reading Assistance Voucher programme. Treating reading impairment in children will reduce the number of teenagers who attempt suicide, drop out of school, or abuse drugs to try and escape the failure that accompanies poor reading ability.Read moreRead less
Longitudinal twin study of literacy, language and attention. The primary practical national benefit will be in the unrivalled picture that emerges about how genetic factors interact with aspects of the familial and educational environment to determine the course of children's development in literacy and language. Policy makers in preschool and school education will be able to use the information to guide curriculum refinement and to develop policies for the early identification of children at d ....Longitudinal twin study of literacy, language and attention. The primary practical national benefit will be in the unrivalled picture that emerges about how genetic factors interact with aspects of the familial and educational environment to determine the course of children's development in literacy and language. Policy makers in preschool and school education will be able to use the information to guide curriculum refinement and to develop policies for the early identification of children at developmental risk in these domains. As an international project, the research will also promote scientific cooperation between Australia, the USA, and Scandinavia in a cutting-edge branch of human psychology, the interaction of genes and environment in psychological development.Read moreRead less

Summary
Developmental disorders of language: Causes and treatments. Disorders in the production and comprehension of spoken and written language affect 15% of children and if untreated persist through adulthood. They are powerfully influenced by genetics, but are uniquely dependent on learning. This initiative aims to create a network unique in the world by uniting researchers with expertise in research from infancy through adulthood, in diagnosis and in treatment, in spoken and written production and c ....Developmental disorders of language: Causes and treatments. Disorders in the production and comprehension of spoken and written language affect 15% of children and if untreated persist through adulthood. They are powerfully influenced by genetics, but are uniquely dependent on learning. This initiative aims to create a network unique in the world by uniting researchers with expertise in research from infancy through adulthood, in diagnosis and in treatment, in spoken and written production and comprehension, and in both cognitive and molecular genetic research. A network of research-oriented clinics for the treatment of these disorders will also be established.Read moreRead less
Exploring the nature of lexical representation. In order to comprehend and produce the words that we know, whether in speech or in writing, we must possess mental representations of each of those words (i.e., "lexical" representations). The aim of the proposed research is to elaborate on the nature of these representations in an attempt to understand more fully the cognitive mechanisms involved in proficient language use. The central idea to be explored is that underlying all lexical functioning ....Exploring the nature of lexical representation. In order to comprehend and produce the words that we know, whether in speech or in writing, we must possess mental representations of each of those words (i.e., "lexical" representations). The aim of the proposed research is to elaborate on the nature of these representations in an attempt to understand more fully the cognitive mechanisms involved in proficient language use. The central idea to be explored is that underlying all lexical functioning is an abstract phonological representation that is influenced by orthography. Furthermore, the possibility will be examined that poorer readers possess less abstract representations than do better readers.Read moreRead less
Phonological development in child speakers of mixed language. In Northern Territory Aboriginal communities where traditional languages are mostly spoken fluently by older people, the home language for many children is a kind of mixed language combining elements of traditional languages, Kriol and English. This project will document for the first time the sound system of this language, and investigate how children's background knowledge of this sound system prepares them to learn words in English ....Phonological development in child speakers of mixed language. In Northern Territory Aboriginal communities where traditional languages are mostly spoken fluently by older people, the home language for many children is a kind of mixed language combining elements of traditional languages, Kriol and English. This project will document for the first time the sound system of this language, and investigate how children's background knowledge of this sound system prepares them to learn words in English and traditional languages. This information is important because it can help parents, teachers and speech pathologists assess and teach Aboriginal children from mixed language backgrounds.Read moreRead less
A cross-linguistic investigation of lexical stress using corpus analyses, behavioural testing and computational modelling. Some languages exhibit variable patterns of emphasis or 'lexical stress' across words ('ZEbra' v 'girAFFE'). This research will provide a more precise understanding of the role of lexical stress in language processing. This will assist educators/clinicians working with normally developing children and those with developmental delays as well as educators/students in second-l ....A cross-linguistic investigation of lexical stress using corpus analyses, behavioural testing and computational modelling. Some languages exhibit variable patterns of emphasis or 'lexical stress' across words ('ZEbra' v 'girAFFE'). This research will provide a more precise understanding of the role of lexical stress in language processing. This will assist educators/clinicians working with normally developing children and those with developmental delays as well as educators/students in second-language learning. It will also lead to improved automatic speech recognition/synthesis - used in commercial applications such as phone banking, edutainment/epistemic computer games and communication devices (speech-to-text dictation systems for those with limited mobility and text-to-speech systems for those unable to speak). Undertaken in collaboration with a high-profile research lab in the UK this project will maintain Australia's competitive edge in cognitive science.Read moreRead less
