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. 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-competitive research.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
Every Day Matters: Reducing School Non-Attendance in Autistic Students. Autistic children miss one day a week of school, three times more than their peers. This significantly impacts their learning, wellbeing and later, their vocational outcomes. This project aims to identify the factors that put autistic children at increased risk of missing school and map the supports and interventions used to reduce school non-attendance. Expected outcomes include an autism-specific model of the how and why s ....Every Day Matters: Reducing School Non-Attendance in Autistic Students. Autistic children miss one day a week of school, three times more than their peers. This significantly impacts their learning, wellbeing and later, their vocational outcomes. This project aims to identify the factors that put autistic children at increased risk of missing school and map the supports and interventions used to reduce school non-attendance. Expected outcomes include an autism-specific model of the how and why school non-attendance is elevated for autistic students. It is anticipated that this model make the important step of enabling teachers and professionals to identify which autistic children are most at risk of absenteeism and select the best strategies to support a positive and beneficial return to school.Read moreRead less
Does phonological awareness help children learn to read? An almost universally-accepted view in the field of reading acquisition is that phonological awareness, or the ability to perceive and manipulate speech sounds, causes a child to be good at learning to read. We argue that, despite the voluminous literature on this issue, it has not been conclusively established that such a causal link exists. To do so requires a project, proposed here, in which completely pre-literate children are selec ....Does phonological awareness help children learn to read? An almost universally-accepted view in the field of reading acquisition is that phonological awareness, or the ability to perceive and manipulate speech sounds, causes a child to be good at learning to read. We argue that, despite the voluminous literature on this issue, it has not been conclusively established that such a causal link exists. To do so requires a project, proposed here, in which completely pre-literate children are selected, their phonological awareness measured, and its relationship with subsequent literacy acquisition followed. Settling this issue will have significant consequences for both theory and practice in reading acquisition and dyslexia.Read moreRead less
Determinants of Audio-Visual effects in degraded and non-degraded speech. Seeing a speaker's face can affect the perception of their speech in a number of ways. This project proposes a detailed comparison of factors that affect Audio-Visual (AV) facilitation of degraded speech detection and identification. Detection-based tasks should be more sensitive to signal based correlations whereas identification-based effects more sensitive to complementary information. The significance of the current pr ....Determinants of Audio-Visual effects in degraded and non-degraded speech. Seeing a speaker's face can affect the perception of their speech in a number of ways. This project proposes a detailed comparison of factors that affect Audio-Visual (AV) facilitation of degraded speech detection and identification. Detection-based tasks should be more sensitive to signal based correlations whereas identification-based effects more sensitive to complementary information. The significance of the current proposal is that it offers both a strategy and a connected series of experiments for determining key behavioural constraints on AV speech integration. Understanding AV interactions will build links between neurophysiological processes and coherent perception and have important implications for AV application.Read moreRead less
Stochastic, Neurally-Plausible Models for Selective Attention and Decision Making. An understanding of the basic cognitive processes involved in attention and decision making is the goal of international research effort in a number of disciplines.

An understanding of the basic cognitive processes involved in attention and decision making is the goal of international research effort in a number of disciplines. The benefits expected from such understanding include improvements in the diagnosis and treatment of a variety of cognitive deficits and improved occupational safety and efficiency in settings involving interaction with complex systems, such air traffic control, airline cockpits, motor vehicles, and process management. By developing mathematical models of these processes and the neural mechanisms that underlie them, this project will contribute to this understanding. It will also provide international postdoctoral opportunties for Australian-trained Ph.D. graduates.Read moreRead less
Understanding the relationship between child maltreatment and language competence: An evidential interviewing perspective. This research aims to develop the first comprehensive and controlled examination of the oral language profiles of maltreated children and how these impact performance in an investigative interview paradigm.

This research aims to develop the first comprehensive and controlled examination of the oral language profiles of maltreated children and how these impact performance in an investigative interview paradigm. This examination is essential for developing strategies for improving the elicitation of evidence from child abuse witnesses. By improving child witness evidence, this research will improve the prosecution and conviction rates of child abuse offences, which will have a deterrent effect on potential offenders. Finally, this research will reduce the stress of witnesses involved in the legal process and provide better screening of children in need of specialised language intervention.Read moreRead less
An Integrated Theory of Attention and Decision Making. Biologically, the fundamental computational task carried out by the human brain is the translation of perception into action. To perform this translation, attentional processes select relevant stimuli from the environment and decision processes then identify the selected stimuli.

Biologically, the fundamental computational task carried out by the human brain is the translation of perception into action. To perform this translation, attentional processes select relevant stimuli from the environment and decision processes then identify the selected stimuli. This project develops an integrated theory of attention and decision making in simple visual tasks, which will help us understand how these tasks are carried out in the brain. Understanding how these tasks are performed biologically will aid in the design of autonomous information-gathering and decision-making agents whose actions simulate human behaviour.

The Stochastic Dynamics of Visual Attention. This project develops and tests a class of mathematical models of how information is represented statistically in the human visual system and how that representation is modified by selective attention. These models synthesise current theories about how the visual system encodes information and how people make judgements on the basis of that information. The domain of application of the existing class of models will be extended to allow them to predi ....The Stochastic Dynamics of Visual Attention. This project develops and tests a class of mathematical models of how information is represented statistically in the human visual system and how that representation is modified by selective attention. These models synthesise current theories about how the visual system encodes information and how people make judgements on the basis of that information. The domain of application of the existing class of models will be extended to allow them to predict performance in more complex settings than has hitherto been the case. A program of experimental studies will test the models by measuring human performance in response to computer-generated stimuli.
