This project aims to illuminate how genetic and environmental factors drive and constrain romantic partner choice. This choice can be the most significant in people’s lives, but how it works is not scientifically understood. This project will analyse the preferences and actual partners of thousands of twins using multivariable statistics and theoretic models of partner choice. The project aims to reveal why some people pair with incompatible partners, and the consequences of partner mismatch for psychological wellbeing and for evolutionary processes driven by mate selection. This could lead to more effective relationship management.Read moreRead less
Human hippocampus subregions organisation and associative memory processes. This proposal will investigate the hippocampus, a highly inter-connected structure containing many subregions. Although considered the memory centre of the brain, we still do not know the exact roles of these subregions during memory processes. Using novel brain neuroimaging acquisition methods and analyses, this project aims to map the internal structure and functions of the hippocampus and its functional networks under ....Human hippocampus subregions organisation and associative memory processes. This proposal will investigate the hippocampus, a highly inter-connected structure containing many subregions. Although considered the memory centre of the brain, we still do not know the exact roles of these subregions during memory processes. Using novel brain neuroimaging acquisition methods and analyses, this project aims to map the internal structure and functions of the hippocampus and its functional networks under different memory conditions and how these functions change with age. The intended outcome of this proposal is to provide the foundations for the first integrated model of human memory and its biological basis and to generate a benchmark against which future development of memory interventions and retraining can be measured.Read moreRead less
Charting age-related changes in the quality of episodic memory. As we get older, our capacity to remember events in rich detail becomes less efficient. The mechanisms driving these changes remain unclear, severely limiting our capacity to accurately assess and optimise memory function in later years. This project aims to determine how memory accuracy and memory quality change across the adult lifespan using cutting-edge experimental and neuroimaging techniques. It will deliver new insights into ....Charting age-related changes in the quality of episodic memory. As we get older, our capacity to remember events in rich detail becomes less efficient. The mechanisms driving these changes remain unclear, severely limiting our capacity to accurately assess and optimise memory function in later years. This project aims to determine how memory accuracy and memory quality change across the adult lifespan using cutting-edge experimental and neuroimaging techniques. It will deliver new insights into the relationship between confidence, memory success and memory quality, and the underlying neural substrates of these processes. This work will provide the essential empirical foundation to augment memory function, ensuring that older adults can continue to participate as active members of society.Read moreRead less
Individualised predictions of circadian timing, sleep, and performance. The body's 24-hour clock regulates when we feel sleepy or alert. In shift workers, disrupted sleep and rhythms leads to fatigue and costly, often deadly, workplace accidents. Existing methods for measuring body clock timing are costly, impractical for operational settings, and do not work in real time. Using a shift-worker population, this project will develop models that accurately predict body timing, sleep/wake patterns, ....Individualised predictions of circadian timing, sleep, and performance. The body's 24-hour clock regulates when we feel sleepy or alert. In shift workers, disrupted sleep and rhythms leads to fatigue and costly, often deadly, workplace accidents. Existing methods for measuring body clock timing are costly, impractical for operational settings, and do not work in real time. Using a shift-worker population, this project will develop models that accurately predict body timing, sleep/wake patterns, and performance for an individual, requiring only a simple activity/light sensor and an assessment of the body clock's sensitivity to light. The new model would revolutionise fatigue management and make safer work environments for millions of shift workers. Read moreRead less

Understanding how the brain combines sensory information. The ease with which we perceive the external world belies the complexity involved in integrating different sensory inputs. How does the brain achieve this fundamental operation? The project will address this question using a multidisciplinary approach that combines computational modelling, brain imaging, and psychophysical techniques. The expected outcomes of the project are a better understanding of how people perceive the world through ....Understanding how the brain combines sensory information. The ease with which we perceive the external world belies the complexity involved in integrating different sensory inputs. How does the brain achieve this fundamental operation? The project will address this question using a multidisciplinary approach that combines computational modelling, brain imaging, and psychophysical techniques. The expected outcomes of the project are a better understanding of how people perceive the world through optimal integration of sensory cues. In addition to advancing basic scientific knowledge, the findings will illuminate perceptual anomalies in normally developing children and will provide a foundation for reducing a debilitating side effect of virtual reality systems known as ‘cybersickness’.Read moreRead less
Intergenerational determinants of child development on school entry. There is widespread interest in preconception determinants of child development but progress relies on multigenerational longitudinal datasets, which are rare internationally. This project takes advantage of a unique opportunity to follow third-generation offspring from one of Australia's oldest longitudinal studies of psychosocial development. The Australian Temperament Project has followed 2000+ young Australians (and their f ....Intergenerational determinants of child development on school entry. There is widespread interest in preconception determinants of child development but progress relies on multigenerational longitudinal datasets, which are rare internationally. This project takes advantage of a unique opportunity to follow third-generation offspring from one of Australia's oldest longitudinal studies of psychosocial development. The Australian Temperament Project has followed 2000+ young Australians (and their families) since 1983, and over 1000 offspring from pregnancy to 4 years since 2012. This project will expand offspring assessments to 6-years, marking the transition to school. Findings have the potential to reshape approaches promoting intergenerational wellbeing and breaking intergenerational cycles of disadvantage.Read moreRead less

This goal of this project is to identify the information the visual system uses to extract the three-dimensional structure and material composition of objects. This project aims to generate an advanced understanding of the information that supports these perceptual abilities and to advance our understanding how this information is learned from exposure to natural scenes. The findings of this work are expected to benefit our understanding of the human visual system, and to provide insights into the information needed to advance the development of deep neural networks (machine learning) that exploit the same information used by humans to guide our behavior and recognize objects and materials.Read moreRead less
Perceiving and misperceiving the causes of optical structure. This project aims to understand the conditions that cause humans to misperceive the shape and surface properties of real-world materials. Most natural materials are translucent to varying degrees, but little is known about how light is transported through them or how such materials are perceived or misperceived. This project will determine the conditions and causes responsible for the misperception of material properties and shape, an ....Perceiving and misperceiving the causes of optical structure. This project aims to understand the conditions that cause humans to misperceive the shape and surface properties of real-world materials. Most natural materials are translucent to varying degrees, but little is known about how light is transported through them or how such materials are perceived or misperceived. This project will determine the conditions and causes responsible for the misperception of material properties and shape, and will offer practical information about what can be done to minimise such misperceptions. The outcomes of the project are expected to lead to new techniques for depicting and manipulating real-world translucent materials in computer graphics, virtual reality, and gaming industries.Read moreRead less
Circadian photoreceptor sensitivity and impacts of modern lighting on sleep. Light has powerful non-visual effects, including effects on sleep. These non-visual effects are mediated by cells in the eye that are most sensitive to blue light. There are large individual differences in sensitivity to non-visual effects of light that are not understood and that would give great insight into suboptimal sleep, which has become widespread in modern society. This study will be the first systematic examin ....Circadian photoreceptor sensitivity and impacts of modern lighting on sleep. Light has powerful non-visual effects, including effects on sleep. These non-visual effects are mediated by cells in the eye that are most sensitive to blue light. There are large individual differences in sensitivity to non-visual effects of light that are not understood and that would give great insight into suboptimal sleep, which has become widespread in modern society. This study will be the first systematic examination of individual differences in the effect of blue light on sleep and will uncover how alterations in the gene responsible for the effects of blue light on sleep (OPN4) contribute to these differences. This will lead to scalable individualised solutions to the unmet problem of how modern light environments impact sleep.Read moreRead less
