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
Improving the competency of police officers in conducting investigative interviews of children. The current research program aims to identify factors that promote and sustain competent police interviewing of children. Although 'best-practice' guidelines in investigative interviewing have been developed, these guidelines are under-utilised by police officers in practice. Research is therefore needed to identify barriers to the implementation of these 'best-practice' guidelines and to test interve ....Improving the competency of police officers in conducting investigative interviews of children. The current research program aims to identify factors that promote and sustain competent police interviewing of children. Although 'best-practice' guidelines in investigative interviewing have been developed, these guidelines are under-utilised by police officers in practice. Research is therefore needed to identify barriers to the implementation of these 'best-practice' guidelines and to test interventions designed to improve their uptake. The expected outcome of this project is the development of interventions that will improve the quality of police training in investigative interviewing. This will increase the quality of evidence obtained from children, especially those who are victims of child abuse.Read moreRead less
Pathways to work engagement, wellbeing and positive teaching among mid-career teachers: The role of personal and workplace resources. Teaching is a highly demanding, yet rewarding career for many. It is also a decidedly stressful occupation associated with high burnout. By following a large sample of teachers recruited ten years earlier into their mid-career, this project investigates the coping and motivational resources that keep them engaged, allowing them to thrive personally and professiona ....Pathways to work engagement, wellbeing and positive teaching among mid-career teachers: The role of personal and workplace resources. Teaching is a highly demanding, yet rewarding career for many. It is also a decidedly stressful occupation associated with high burnout. By following a large sample of teachers recruited ten years earlier into their mid-career, this project investigates the coping and motivational resources that keep them engaged, allowing them to thrive personally and professionally in different kinds of school environments, versus pathways that predict to burnout, ill-being and negative teaching behaviours. Selected subgroups who were most at risk and most positively engaged earlier in their career will be the focus of longitudinal case studies to uncover more nuanced processes promoting positive and negative pathways.Read moreRead less

Attracting and sustaining engaged science and mathematics teachers. This project will examine what attracts or deters potential, future and practising teachers of the sciences and mathematics, by focusing on current teachers, school and university students in Queensland. Promises of a technological revolution and rapid economic development will be hollow if students do not study sciences and mathematics, and there are too few qualified teachers. This project will identify where to intervene in the science and mathematics teacher supply pipeline, and policy levers to attract and sustain quality teachers. The project is expected to uncover what attracts or deters teachers of science and mathematics—disciplines essential to industry innovation, a skilled workforce and productivity growth.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
Attention and hazard perception while driving: how experts see the scene. All drivers have 'drifted-off' or failed to see something that was clearly in view, yet trained expert drivers appear to rarely experience this. This project aims to understand in both 'normal' drivers and expert drivers, attentional mechanisms that control distraction and the perception of hazards, which is critical to road safety and young driver training.
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. 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 traffi ....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. 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
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.

Remembering that things have changed: A behavioural, pharmacological and biochemical examination of the differences between consolidation and re-consolidation in the day-old chick. This project has five national benefits. 1) It addresses a fundamental scientific and practical problem: to determine whether re-consolidation is actually a repetition of consolidation or in fact a distinct process; 2) it will provide a comprehensive account of how the two processes compare at a biochemical level; 3) ....Remembering that things have changed: A behavioural, pharmacological and biochemical examination of the differences between consolidation and re-consolidation in the day-old chick. This project has five national benefits. 1) It addresses a fundamental scientific and practical problem: to determine whether re-consolidation is actually a repetition of consolidation or in fact a distinct process; 2) it will provide a comprehensive account of how the two processes compare at a biochemical level; 3) it may ultimately provide a pharmacological and behavioural approach to modifying troubling or unwanted memories such as the concerns which may result in post-traumatic stress disorder; 4) it will contribute to Australia's international reputation in behavioural neuroscience and 5) it will provide outstanding training opportunities for Australian undergraduate and postgraduate research students in behavioural neuroscience.Read moreRead less
