Eyes on the prize: Investigating attentional economics. We spend our lives surrounded by stimuli relating to reward and risk (adverts, games, social media etc). Recent research suggests that learning about reward and risk influences our attention, often despite our best efforts. This project will build on recently developed procedures using eye-tracking to investigate how learning about reward and risk modulates what we pay attention to, and what we ignore.

We spend our lives surrounded by stimuli relating to reward and risk (adverts, games, social media etc). Recent research suggests that learning about reward and risk influences our attention, often despite our best efforts. This project will build on recently developed procedures using eye-tracking to investigate how learning about reward and risk modulates what we pay attention to, and what we ignore. Findings will be used to develop computational models of ‘attentional economics’ that account for, and predict, when we will be distracted by reward- and risk-related stimuli. This research will enhance the world-class status of Australian cognitive psychology, and will shed light on processes implicated in addiction and related behaviours.Read moreRead less
Gaining control of the future: The cognitive development of foresight. Because humans can anticipate their limitations, they can act in the present to shape their future for the better.
This project aims to chart four key developmental processes by which children gain this control over their future
outcomes. It will use novel experimental paradigms to map children’s growing ability to compensate for their limits
with strategic planning, and to improve their future capacities by acquiring new kno ....Gaining control of the future: The cognitive development of foresight. Because humans can anticipate their limitations, they can act in the present to shape their future for the better.
This project aims to chart four key developmental processes by which children gain this control over their future
outcomes. It will use novel experimental paradigms to map children’s growing ability to compensate for their limits
with strategic planning, and to improve their future capacities by acquiring new knowledge and innovating
technical solutions. The cognitive underpinnings of these critical behaviours are still poorly understood. This
project will therefore provide the essential empirical foundation for fostering the development of wiser, more
skilled, and more innovative young people.Read moreRead less
Towards an integrated model of reasoning and reasoning development. This project aims to identify the core cognitive processes that underlie different forms of reasoning and how they develop. The project intends to use a signal detection framework to derive detailed computational models of reasoning which can then be tested through Bayesian computational modelling as well as the first systematic investigation of developmental change in reasoning processes. Expected outcomes include a more princi ....Towards an integrated model of reasoning and reasoning development. This project aims to identify the core cognitive processes that underlie different forms of reasoning and how they develop. The project intends to use a signal detection framework to derive detailed computational models of reasoning which can then be tested through Bayesian computational modelling as well as the first systematic investigation of developmental change in reasoning processes. Expected outcomes include a more principled and comprehensive computational model of reasoning in both adults and children. The project should provide significant benefits by helping to resolve long-standing debates about how humans reason complex arguments relevant to everyday lives and guide development of more effective methods for teaching reasoning.Read moreRead less

Music and speech as a window into the predictive brain . Prediction is fundamental to daily life, and yet we know little about how this central process works in the brain. This research program aims to provide in-depth insight into predictive processing by investigating the precise, culturally relevant, and communicative domains of music and speech. The research expects to reveal cognitive and neural correlates of “what” will occur and “when” it will occur, while exploiting the musician brain as ....Music and speech as a window into the predictive brain . Prediction is fundamental to daily life, and yet we know little about how this central process works in the brain. This research program aims to provide in-depth insight into predictive processing by investigating the precise, culturally relevant, and communicative domains of music and speech. The research expects to reveal cognitive and neural correlates of “what” will occur and “when” it will occur, while exploiting the musician brain as a model for plasticity. Expected outcomes include a multi-dimensional model of prediction and its neural markers that will lay the foundation to investigate impaired predictive processing. This should substantially benefit health and education by providing perspectives for training and rehabilitation.Read moreRead less
Investigating the characteristics of older adults' conversation behaviour. The project aims to determine the factors that negatively impact older adults’ ability to engage in conversation. This is an important health issue; conversations are essential for communicating needs and maintaining social links; reduced social engagement leads to serious health problems and anticipates cognitive decline. The project will compile profiles of older adults' auditory-visual conversation behavior and indices ....Investigating the characteristics of older adults' conversation behaviour. The project aims to determine the factors that negatively impact older adults’ ability to engage in conversation. This is an important health issue; conversations are essential for communicating needs and maintaining social links; reduced social engagement leads to serious health problems and anticipates cognitive decline. The project will compile profiles of older adults' auditory-visual conversation behavior and indices of perceptual, cognitive and social skills. A path model will link these data to ratings of social engagement and satisfaction. By identifying factors leading to low ranked conversations, evidence-based guidelines can be developed for older adults and their carers to enhance communication and improve health and well-being.Read moreRead less
Hippocampal regulation of goal-directed decision-making. The hippocampus is a part of the brain that is central to learning and memory yet little is known about its role in decision-making. It is the aim of this application to provide the first detailed, causal evidence of hippocampal regulation of decision-making. This is significant because many mental health disorders and dementias that involve decision-making deficits are characterised by hippocampal dysfunction, but any direct link between ....Hippocampal regulation of goal-directed decision-making. The hippocampus is a part of the brain that is central to learning and memory yet little is known about its role in decision-making. It is the aim of this application to provide the first detailed, causal evidence of hippocampal regulation of decision-making. This is significant because many mental health disorders and dementias that involve decision-making deficits are characterised by hippocampal dysfunction, but any direct link between these factors is unknown. The outcomes of the current grant will provide the first evidence of that link, thus providing deeper understanding of the neurophysiological mechanisms of these disorders, which could eventuate in the creation of more beneficial treatments.

Contextual modulation in high-level vision. This project aims to understand the nature and mechanisms of spatial contextual modulation and the relationship between spatial and temporal context. Contextual modulation refers to the sometimes profound changes in the appearance of the visual image caused by interactions across space and time. Little work has been done to examine whether spatial context effects exist for high-level attributes of objects, and socially relevant stimuli such as heads an ....Contextual modulation in high-level vision. This project aims to understand the nature and mechanisms of spatial contextual modulation and the relationship between spatial and temporal context. Contextual modulation refers to the sometimes profound changes in the appearance of the visual image caused by interactions across space and time. Little work has been done to examine whether spatial context effects exist for high-level attributes of objects, and socially relevant stimuli such as heads and bodies. This project expects to provide new knowledge regarding the way that contextual modulation is mediated by interactions within the normal human visual system. This will provide significant societal benefits as contextual interactions in sensory processing can have profound consequences for our perceptual experience.Read moreRead less

Understanding the neural dynamics of colour constancy and feature binding. A key open question in visual neuroscience is how sensory input is combined with higher-level influences (e.g. attentional state). This project aims to address this using neuroimaging techniques combined with sophisticated analysis methods that were recently developed to measure when stimulus-related information is being transferred between different brain regions.

A key open question in visual neuroscience is how sensory input is combined with higher-level influences (e.g. attentional state). This project aims to address this using neuroimaging techniques combined with sophisticated analysis methods that were recently developed to measure when stimulus-related information is being transferred between different brain regions. These methods will be used to investigate the neural mechanisms underlying two fundamental phenomena in visual perception: feature binding and colour constancy. Understanding the neural mechanisms by which sensory input interacts with attention for these tasks would be a major advance in understanding how interactions between brain regions give rise to our perceptual experiences.Read moreRead less
