Auditory spatial perception during head movements. Orienting to stimuli frequently involves eye and head movements. This improves localisation, yet brings attendant problems (eg, blurring). These problems are well understood in vision, but not in audition, despite evidence for common neural mechanisms. We will examine auditory (and visual) localisation during head movements, showing head movements produce auditory suppression and spatial distortions (analogous to visual saccadic effects). This w ....Auditory spatial perception during head movements. Orienting to stimuli frequently involves eye and head movements. This improves localisation, yet brings attendant problems (eg, blurring). These problems are well understood in vision, but not in audition, despite evidence for common neural mechanisms. We will examine auditory (and visual) localisation during head movements, showing head movements produce auditory suppression and spatial distortions (analogous to visual saccadic effects). This will demonstrate the malleability of auditory spatial perception and the impoverished sensitivity of audition during head and self-motion. Knowledge of these distortions will inform applications such as cockpit design, where orienting to auditory signals is common, and other human/computer interfaces.

Implicit transmission of embodied culture. Is a culturally diverse, yet socially integrated community possible? In multicultural societies such as Australia, this is a pressing and significant question. To form and maintain a vibrant and prosperous community in the face of globalization, it is essential to understand the fundamental processes by which cultures are formed and transformed in everyday social activities. This project examines one such process, implicit cultural transmission, propose ....Implicit transmission of embodied culture. Is a culturally diverse, yet socially integrated community possible? In multicultural societies such as Australia, this is a pressing and significant question. To form and maintain a vibrant and prosperous community in the face of globalization, it is essential to understand the fundamental processes by which cultures are formed and transformed in everyday social activities. This project examines one such process, implicit cultural transmission, proposed to function in the nonconscious transmission of cultural information. Understanding the dynamics of this subtle, yet pervasive, mode of cultural influence is central to a full appreciation of how one's own culture and those of others' integrate and flourish.Read moreRead less
Social cognitive change in late adulthood. This project aims to develop and test a model of how normal adult ageing affects the ability to perceive and interpret social cues, a critical predictor of social competency and well-being, and identify the most important determinants of any age-related changes. This project predicts that older adults who have the greatest difficulties perceiving and interpreting social cues will also have the poorest social function and well-being, so better understand ....Social cognitive change in late adulthood. This project aims to develop and test a model of how normal adult ageing affects the ability to perceive and interpret social cues, a critical predictor of social competency and well-being, and identify the most important determinants of any age-related changes. This project predicts that older adults who have the greatest difficulties perceiving and interpreting social cues will also have the poorest social function and well-being, so better understanding the mechanistic factors that drive resilience and risk for these difficulties is expected to have direct and important implications for Australia’s growing older adult community.Read moreRead less
Time discounting in late career financial and activity planning. A new career decision model of retirement activity and financial planning will be tested that combines hyperbolic delay discounting with exponential interest growth, while also examining the impact of risk framed in terms of changing goverment tax legislation and uncertain health. The role of expertise and simulated training in reducing time discounting will be examined, and results combined to form a late career web assistance pro ....Time discounting in late career financial and activity planning. A new career decision model of retirement activity and financial planning will be tested that combines hyperbolic delay discounting with exponential interest growth, while also examining the impact of risk framed in terms of changing goverment tax legislation and uncertain health. The role of expertise and simulated training in reducing time discounting will be examined, and results combined to form a late career web assistance program. Improving predictions of the decision to retire will benefit individuals, financial planners, investors and employing organisations.Read moreRead less
Learning to control fear. This project uses extinction of fear in rats to model means to control human fear. Its aims are to determine why patients must be exposed to trauma-related cues to learn to control their fear and when knowledge about the current relation between the cues and the trauma is sufficient for patients to overcome the fear normally elicited by trauma-related cues.
Face-space: linking three-dimensional shape and human perception across changing viewing conditions. People, and increasingly machines, use faces to identify and interact with people. One source of information available for this is the three-dimensional (3D) shape of the face. This information, unlike a photograph, does not change with lighting and viewpoint. This project will link measurements of face shape to the perceived similarities and differences between faces we use to make decisions. ....Face-space: linking three-dimensional shape and human perception across changing viewing conditions. People, and increasingly machines, use faces to identify and interact with people. One source of information available for this is the three-dimensional (3D) shape of the face. This information, unlike a photograph, does not change with lighting and viewpoint. This project will link measurements of face shape to the perceived similarities and differences between faces we use to make decisions. This will facilitate the use of 3D databases in diverse applications including establishing identity, making facial reconstructions of victims of crime or disaster, making databases searchable, computer animation, archaeology, and plastic surgery. In particular the work will make physical databases relevant to human perception. Read moreRead less
Work Design Matters: The Dynamic Interplay of Work, Person and Context. Work design is critical for social and economic outcomes, as exemplified by the International Labour Office's 'Decent Work agenda'. This project first proposes new, long-term dynamic processes by which personality and demographics, and their interactions, shape or constrain individuals' opportunities for high quality work. Second, it considers how family, education, and workplace factors mitigate the pathways between these i ....Work Design Matters: The Dynamic Interplay of Work, Person and Context. Work design is critical for social and economic outcomes, as exemplified by the International Labour Office's 'Decent Work agenda'. This project first proposes new, long-term dynamic processes by which personality and demographics, and their interactions, shape or constrain individuals' opportunities for high quality work. Second, it considers how family, education, and workplace factors mitigate the pathways between these individual variables and work design. Finally, taking account of contemporary challenges in today's organisations, it examines how work design affects the person, including their health, performance, behaviour, and cognition. The project aims to address these questions using a unique longitudinal cohort study, the Raine Study.Read moreRead less
Understanding the learning and development of employees' emotion regulation strategies over time: rethinking the paradigm. This project investigates how new employees develop strategies for managing emotions at work. Using applied and laboratory designs, this research extends our understanding of how organisational socialisation processes influence new employees' management of emotions and identifies the levers to improve employee wellbeing, productivity and retention.
Organization and Plasticity of Visual Processing in a Miniature Brain. To recognise objects a brain must have an internal representation of most likely object appearance. Two ways in which brains may posses this information include a hard wired template system, and/or the neuroplasticity to learn novel objects. Recent investigations on honeybee vision show that this animal can learn to recognise very difficult objects, although currently we do not know how the miniaturised bee brain manages thes ....Organization and Plasticity of Visual Processing in a Miniature Brain. To recognise objects a brain must have an internal representation of most likely object appearance. Two ways in which brains may posses this information include a hard wired template system, and/or the neuroplasticity to learn novel objects. Recent investigations on honeybee vision show that this animal can learn to recognise very difficult objects, although currently we do not know how the miniaturised bee brain manages these tasks. This project will reveal changes that occur in the processing of visual objects by the bee's brain with increasing experience, with potential applications including robotics or building interfaces between sensors and biological systems.Read moreRead less
Extending the theory and measurement of personal values and testing relations of values to attitudes and behaviour. Personal values indicate what is important to us, guide our behaviour and reflect real differences between cultures, social classes, occupations, and religions. This project seeks to refine the theory and measurement of personal values across cultures to better understand the motivations that lie behind attitudes and behaviours.
