Summary
Although most children acquire speech and language skills comparatively effortlessly, it has become increasingly apparent that many do not. More importantly, this sizeable group accounts for great subsequent population health, social and economic burden. Research in the field has been underfunded and fragmented, resulting in evidence gaps, limited capacity, and disparate guidance for policy-makers. We will address these issues, acting as a vehicle and an ongoing catalyst for internationally-comp ....Although most children acquire speech and language skills comparatively effortlessly, it has become increasingly apparent that many do not.

Research in the field has been underfunded and fragmented, resulting in evidence gaps, limited capacity, and disparate guidance for policy-makers. We will address these issues, acting as a vehicle and an ongoing catalyst for internationally-competitive research.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
The development of feedforward mechanisms of motor control: The role of efference copy in motor skill development. Our work provides preliminary evidence that deficits in efference copy (or feedforward planning) underlie impaired motor skill development in children (or Developmental Coordination Disorder - DCD). The aim of this project is to advance our understanding of normal and abnormal motor development by examining this hypothesis in a large sample, longitudinally. We will examine variati ....The development of feedforward mechanisms of motor control: The role of efference copy in motor skill development. Our work provides preliminary evidence that deficits in efference copy (or feedforward planning) underlie impaired motor skill development in children (or Developmental Coordination Disorder - DCD). The aim of this project is to advance our understanding of normal and abnormal motor development by examining this hypothesis in a large sample, longitudinally. We will examine variations in the presentation of clumsiness, cognitive deficit(s) in different subtypes, and changes in presentation with age. We predict that deficits in efference copy will explain departures from normal motor skill development in most children. We also predict that imagery training will ameliorate the deficit.Read moreRead less
Development of rapid, online motor control in children. Movement is the primary means by which young children develop understanding of the world. The studies described in this project will provide important insights into the development of movement skill in children and the underlying causes of motor impairment. In particular we aim to understand how thought and action are coordinated in children, supporting the ability to perform more efficient movements. Hence, our work will inform the traini ....Development of rapid, online motor control in children. Movement is the primary means by which young children develop understanding of the world. The studies described in this project will provide important insights into the development of movement skill in children and the underlying causes of motor impairment. In particular we aim to understand how thought and action are coordinated in children, supporting the ability to perform more efficient movements. Hence, our work will inform the training and practice of movement educators and physical therapists, transcending some of the myths of clinical theory. This work will have important implications for identifying and training children at risk for motor impairment. Read moreRead less

Summary
One possible cause of specific language impairment (SLI) and specific reading disability (SRD; commonly known as dyslexia) is an inability to discriminate between sounds. Such an impairment could affect the ability to discriminate between simple speech sounds (phonemes) which are the basic building blocks for developing spoken language and reading skills. How many children with SLI or SRD have poor sound discrimination? What pattern of spoken language and reading impairments do these children ha ....One possible cause of specific language impairment (SLI) and specific reading disability (SRD; commonly known as dyslexia) is an inability to discriminate between sounds. Such an impairment could affect the ability to discriminate between simple speech sounds (phonemes) which are the basic building blocks for developing spoken language and reading skills. How many children with SLI or SRD have poor sound discrimination? What pattern of spoken language and reading impairments do these children have as a result of this impairment? Can poor sound discrimination be fixed? If it can, does it improve spoken language and reading impairments? And if it does, does it have an immediate effect or does it take some time to make a difference? These are some of the questions that will be addressed by this research. The answers will help us develop a training program that focuses specifically on improving the sound discrimination abilities of children who really need it. This will be a more efficient and inexpensive (if not free) than the Fast ForWord program that trains multiple non-verbal and verbal processing abilities regardless of whether a child has an impairment in all (or any) of these abilities and is therefore time consuming (approximately 80 hours) and expensive (approximately $AUD2000). The data will also help up better identify the spoken and written language profiles that characterise children who have sound discrimination deficits so we can better predict whether they would benefit from training programs such as Fast ForWord. And the data will tell use whether impaired sound discrimination can be used to predict whether infants might be at risk for later spoken language and reading problems.Read moreRead less
Improving eyewitness identification accuracy using free-report lineups. There is major national and community interest in the successful conduct of criminal investigations. This research addresses the accuracy of eyewitness identification tests. Specifically, we investigate whether developing lineup procedures that separate out witnesses who are unsure of their response will prevent erroneous identifications. Progress on this issue makes an important contribution to decisions about the ideal lin ....Improving eyewitness identification accuracy using free-report lineups. There is major national and community interest in the successful conduct of criminal investigations. This research addresses the accuracy of eyewitness identification tests. Specifically, we investigate whether developing lineup procedures that separate out witnesses who are unsure of their response will prevent erroneous identifications. Progress on this issue makes an important contribution to decisions about the ideal lineup procedure, thereby preventing innocent people from being prosecuted and perpetrators being free to re-offend. Additionally the international collaboration on the project will increase the visibility of Australian social science research and provide crucial development opportunities for young Australian scientists.Read moreRead less
Identifying the bad guy with deadlined confidence judgments. There is major interest in the successful conduct of criminal investigations.

There is major interest in the successful conduct of criminal investigations. Identity tests are commonly used in such investigations, but eyewitness decision accuracy is still unacceptably low. While eyewitness memory research has already contributed significantly to the development of procedures that improve the diagnosticity of identification decisions, our proposal offers radical new alternatives that can significantly improve diagnosticity. In refining and evaluating these alternatives we will boost the profile of Australian science research and provide rich international training environments for young Australian and overseas scientists.Read moreRead less
Interviewing eyewitnesses: Enhancing output quantity and diagnosing accuracy. Although there has been general international agreement that open-ended police interviews (e.g., the Cognitive Interview) enhance output quantity and accuracy, it is also well documented that police investigators often depart from these procedures in order to probe for additional information. An approach to eyewitness interviewing that allows police to elicit greater detail while able to assess likely accuracy not only ....Interviewing eyewitnesses: Enhancing output quantity and diagnosing accuracy. Although there has been general international agreement that open-ended police interviews (e.g., the Cognitive Interview) enhance output quantity and accuracy, it is also well documented that police investigators often depart from these procedures in order to probe for additional information. An approach to eyewitness interviewing that allows police to elicit greater detail while able to assess likely accuracy not only has the potential to be widely adopted but would also provide a major breakthrough in the investigation of crimes and other incidents where interview data are so critical. This in turn would further enhance the profile of Australian (and UK) forensic science.Read moreRead less
Captions for the Deaf and Hearing Impaired: Availability versus Accessibility. The availability of educational, informational and recreational services for deaf and hearing-impaired people has been dramatically facilitated by (i) increased television captioning due to the 2001 introduction of the Television Broadcasting Services Act; and (ii) trial introduction of real-time captioning in educational settings.

The availability of educational, informational and recreational services for deaf and hearing-impaired people has been dramatically facilitated by (i) increased television captioning due to the 2001 introduction of the Television Broadcasting Services Act; and (ii) trial introduction of real-time captioning in educational settings. These innovations must be matched by equally innovative ways of increasing the accessibility of captions, which is currently limited by English literacy, caption speed, and caption reduction techniques. Here, systematic manipulation of these factors in experiments on television captioning with adults and educational captioning with children will determine how resources might best be directed to improving caption accessibility.Read moreRead less
Emotion in voice matters: Advancing a neural model of auditory emotion perception. Accurate perception of emotion in others is fundamental for positive social relationships, and speaking is the most common source of information from which a person will infer emotional intent.

Accurate perception of emotion in others is fundamental for positive social relationships, and speaking is the most common source of information from which a person will infer emotional intent. This project capitalises on recent advances in brain imaging technologies to develop a neural theory of vocal emotion perception that integrates research across neuro-cognitive, affective, and language disciplines. This will put Australia at the forefront of an important emerging research field 'social neuroscience', raising our international profile in this area. Findings will provide the theoretical knowledge that is currently lacking in the development of targeted remediation programs for individuals suffering from social communication problems.Read moreRead less
