The neuronal bases of consciousness and attention. Why and how do some electrical activities in the brain make us see, hear and feel pain? Why other neural activities remain non-conscious? This project will utilise visual illusions combined with a range of state-of-the-art neuroimaging techniques to understand what kind of neuronal mechanisms underlie attention and consciousness.

Autobiographical memory as a key to successful psychological functioning. This project aims to develop a theoretical framework that will explain how the retrieval of autobiographical memories may be essential for good mental health. Using cutting-edge statistical techniques, an international team of researchers will track young adults over a number of years to explore whether autobiographical memory retrieval underlies development of both adaptive and dysfunctional aspects of psychological funct ....Autobiographical memory as a key to successful psychological functioning. This project aims to develop a theoretical framework that will explain how the retrieval of autobiographical memories may be essential for good mental health. Using cutting-edge statistical techniques, an international team of researchers will track young adults over a number of years to explore whether autobiographical memory retrieval underlies development of both adaptive and dysfunctional aspects of psychological functioning. Expected project outcomes will indicate whether future researchers could enhance autobiographical memory to promote healthy development and potentially prevent mental illness from ever emerging. This will allow future researchers to use cognitive science to benefit the mental health of Australians.Read moreRead less
Humans as animals and objects: the psychology of dehumanisation. This project will clarify how some individuals and groups as perceived as less than human. It will examine how some groups are subtly seen as animal-like and how some media images objectify individuals. It will yield a deeper understanding of how people may be degraded, dismissed, vilified and dehumanised.
A social psychology of affective disturbance. We are in the midst of a depression and anxiety epidemic that cannot be explained by focusing on individual experiences alone. We desperately need to understand the cultural contributors to depression and anxiety, thereby providing insight into the epidemiology of these conditions. Drawing on experimental studies, longitudinal sampling of daily emotional experiences, and multi-national data, the research will show how cultural contexts may exacerbate ....A social psychology of affective disturbance. We are in the midst of a depression and anxiety epidemic that cannot be explained by focusing on individual experiences alone. We desperately need to understand the cultural contributors to depression and anxiety, thereby providing insight into the epidemiology of these conditions. Drawing on experimental studies, longitudinal sampling of daily emotional experiences, and multi-national data, the research will show how cultural contexts may exacerbate individual-level affective disturbance and demonstrate the processes through which occurs. The findings will make a timely and much needed contribution to public policy decisions and preventive health care.Read moreRead less
The effect of cochlear implants on cognitive decline in ageing Australians. This project aims to investigate the impact of cochlear implants on cognitive function in elderly people with deafness. Deafness has been found to be independently associated with a 30–40 per cent accelerated rate of cognitive decline in elderly adults. There is currently no effective treatment for cognitive decline. The intended outcomes of this observational study will help us to understand the biological process of co ....The effect of cochlear implants on cognitive decline in ageing Australians. This project aims to investigate the impact of cochlear implants on cognitive function in elderly people with deafness. Deafness has been found to be independently associated with a 30–40 per cent accelerated rate of cognitive decline in elderly adults. There is currently no effective treatment for cognitive decline. The intended outcomes of this observational study will help us to understand the biological process of cognitive decline, whether hearing loss is causal, and whether the process can be altered. These findings should be applicable to all individuals with hearing loss. If cochlear implants delay cognitive decline, this would significantly affect policy, quality of life for the elderly, and the cost to society.Read moreRead less
Mapping, understanding and manipulating the human brain connectome with MRI. The human brain is an extraordinarily complex network, comprising millions of nerve cells connected by trillions of fibres. Understanding this intricate web of connectivity – the so-called human connectome – has become a central goal of neuroscience and is comparable in scale to the human genome project. This project will develop new brain imaging methods for accurately mapping the connectome. It will investigate how in ....Mapping, understanding and manipulating the human brain connectome with MRI. The human brain is an extraordinarily complex network, comprising millions of nerve cells connected by trillions of fibres. Understanding this intricate web of connectivity – the so-called human connectome – has become a central goal of neuroscience and is comparable in scale to the human genome project. This project will develop new brain imaging methods for accurately mapping the connectome. It will investigate how information is communicated between its different regions and how individual differences in brain network function relate to our genetic make-up. It will also determine whether we can manipulate the function of specific circuits of the connectome in a targeted way, in the hope of developing new treatments for brain disorders.Read moreRead less
Emotion regulation in daily life: Capturing context and flexibility. This project aims to understand the role of contextual and individual factors in effective emotion regulation in daily life. The ability to manage emotions is central to virtually every aspect of psychosocial functioning and wellbeing. However, because research in this domain has relied heavily on laboratory methods, very little is known about emotion regulation as it naturally occurs in daily life. Using cutting-edge mobile te ....Emotion regulation in daily life: Capturing context and flexibility. This project aims to understand the role of contextual and individual factors in effective emotion regulation in daily life. The ability to manage emotions is central to virtually every aspect of psychosocial functioning and wellbeing. However, because research in this domain has relied heavily on laboratory methods, very little is known about emotion regulation as it naturally occurs in daily life. Using cutting-edge mobile technologies, this project aims to uncover when, and for whom, various forms of emotion regulation are most effective in daily life. Besides a significantly improved scientific understanding of emotion regulation, this project is expected to inform the development of novel person - and situation-specific interventions in the many applied domains involving emotion regulation.Read moreRead less
Attentional asymmetries for navigation in healthy and clinical groups. This project plans to investigate how differences in attentional capacity between the left and right sides of the brain affect the ability to walk or manoeuvre vehicles between obstacles. To navigate our environment and avoid obstacles, we need to attend to stimuli that are important and ignore those that are not. Unfortunately, the brain’s attentional capacity is limited, which can result in errors and collisions. Using the ....Attentional asymmetries for navigation in healthy and clinical groups. This project plans to investigate how differences in attentional capacity between the left and right sides of the brain affect the ability to walk or manoeuvre vehicles between obstacles. To navigate our environment and avoid obstacles, we need to attend to stimuli that are important and ignore those that are not. Unfortunately, the brain’s attentional capacity is limited, which can result in errors and collisions. Using the techniques of cognitive neuroscience, the project aims to provide a better understanding of the cognitive and neural mechanisms that govern attention in an applied setting. It expects to identify the factors that exacerbate lapses in attention and collisions. The effect of everyday impediments such as mobile phones, alcohol and fatigue will be investigated together with means of minimising these attentional lapses and improving safety.Read moreRead less

The ups and downs of visuospatial attention. The brain has a remarkable capacity to provide a coherent experience of the world by seamlessly integrating sights and sounds from different locations. It is only after brain damage, or when faced with a high attentional load, that our limitations become apparent. The project aims to investigate these limitations by determining how spatial location influences attention in relation to distractibility, cross-modal input and emotionality.

The brain has a remarkable capacity to provide a coherent experience of the world by seamlessly integrating sights and sounds from different locations. It is only after brain damage, or when faced with a high attentional load, that our limitations become apparent. The project aims to investigate these limitations by determining how spatial location influences attention in relation to distractibility, cross-modal input and emotionality. Eye tracking and physiological measures of arousal will be combined with traditional cognitive measures to provide a deeper understanding of spatial attention. This project aims to improve attentional models and develop innovative strategies to increase safety by decreasing inattention and distraction.Read moreRead less
What is the functional significance of mirror neurons? Contrasting the adaptation and association models of the mirror neuron system. Mirror neurons are a type of brain cell that are thought to underlie empathy and cause autism. Alternatively, however, mirror neurons might instead arise from repeated associations between what we see and what we do. This study uses brain stimulation and neuroimaging techniques to determine the function of mirror neurons.
