The Australian Centre of Excellence in Twin Research will build on the Australian Twin Registry, which for 30 years has played an integral part in health & medical research. The new Centre aims to expand a state-of-the-art resource for conducting research, bring together leading national and international researchers from across disciplines, and build capacity in people, techniques, and expertise to continue to enable twin research to address major health and medical issues.
Multidimensional unfolding: the latitude of acceptance and the structure of the single peaked response process in a multidimensional space. The latitude of acceptance and the operational function that structures the single peaked response process have only recently been understood as central to unidimensional models for the measurement of attitude, preference and choice. They have been neglected in multidimensional models. This project will formalise these two central components in a multidimens ....Multidimensional unfolding: the latitude of acceptance and the structure of the single peaked response process in a multidimensional space. The latitude of acceptance and the operational function that structures the single peaked response process have only recently been understood as central to unidimensional models for the measurement of attitude, preference and choice. They have been neglected in multidimensional models. This project will formalise these two central components in a multidimensional space. The operational function governs the relationship between any item-person distance and the latitude of acceptance defines a multidimensional hyper-sphere within which the more positive response is more likely. The project will articulate and operationalise these models for a range of typical response formats from ranking to pairwise preferences.Read moreRead less
Advancing the application of Rasch models to the level of tests: estimating person parameters independently of all test parameters. The project advances recent theoretical work on Rasch models which makes it possible to compare estimates of person locations on a scale independently of all properties of the tests to which they have responded. The project aims to circumvent the current methods of test equating where various distribution assumptions are implied.
Evaporative water loss and relative water economy in marsupials. Marsupials are an iconic element of the Australian fauna, so the robust physiological database we will establish has intrinsic educational and scientific value to Australians. We will provide important methodological and analytical advances at the cutting edge of physiological research. This project will sustain our leading role as marsupial physiologists in the international scientific community, contribute to the high-quality tra ....Evaporative water loss and relative water economy in marsupials. Marsupials are an iconic element of the Australian fauna, so the robust physiological database we will establish has intrinsic educational and scientific value to Australians. We will provide important methodological and analytical advances at the cutting edge of physiological research. This project will sustain our leading role as marsupial physiologists in the international scientific community, contribute to the high-quality training of research students, foster national and international collaboration, and generally enhance the scientific profile of Australia. Knowledge of a species' biology and its interactions with the environment are essential for conservation in the face of landscape modification and climate change.Read moreRead less

The intended outcomes of the project include a state-of-the-art interactive values-based website, basic knowledge about Australian values, values change and value-related behaviour, and business insight into value-based marketing. This project aims to apply the ....Dynamic relations between values and consumer behaviour: age and life-stage. This project aims to understand the complex relations between people’s life goals and their consumption behaviour, exploring age, life-stage and cohort effects. The intended outcomes of the project include a state-of-the-art interactive values-based website, basic knowledge about Australian values, values change and value-related behaviour, and business insight into value-based marketing. This project aims to apply the knowledge gained from a large scale study into Australian values and value change across the adult life-span in order to understand how people’s values influence their consumer and other decisions; providing information that will enable Australian organisations to improve their marketing activities and the nature of their promotional appeals.Read moreRead less
Anglos Abroad: Memoirs of Immersion in a Foreign Language and Culture. A study of Anglophone narratives of language immersion offers a significant intellectual resource for thinking about ways in which Australian non-immigrant selves are shaped by culture and language: an issue with important implications for just practises within a wide range of national institutions and agencies, including education, immigration and social work. It thus contributes to the priority goal of strengthening Austral ....Anglos Abroad: Memoirs of Immersion in a Foreign Language and Culture. A study of Anglophone narratives of language immersion offers a significant intellectual resource for thinking about ways in which Australian non-immigrant selves are shaped by culture and language: an issue with important implications for just practises within a wide range of national institutions and agencies, including education, immigration and social work. It thus contributes to the priority goal of strengthening Australia's social and economic fabric (Research Priority 2). It also contributes to enhancing our capacity to interpret and engage with our region and the world through a greater understanding of other languages and cultures (Research Priority 4).Read moreRead less
Categorization and Working Memory: Bridging two Pillars of Cognition. Categorization is a fundamental cognitive skill that underlies much expert behavior, including medical diagnosis. A given task often gives rise to widely divergent strategies across individuals, and flawed strategies have been implicated in prediction errors of experts (e.g., bush fire fighters). This project seeks to identify the underlying variables that determine an individual's strategy acquisition by relating working memo ....Categorization and Working Memory: Bridging two Pillars of Cognition. Categorization is a fundamental cognitive skill that underlies much expert behavior, including medical diagnosis. A given task often gives rise to widely divergent strategies across individuals, and flawed strategies have been implicated in prediction errors of experts (e.g., bush fire fighters). This project seeks to identify the underlying variables that determine an individual's strategy acquisition by relating working memory performance to categorization. Working memory is a core cognitive construct that is quite well understood, but its relationship to category learning has so far remained unexplored. Being able to predict the development of categorization strategies can help maximize expert performance.Read moreRead less
Are two processes one too many? An investigation of the viability of the dual-process model of recognition memory. Memory is the glue that holds together our lives and personal identities. While psychologists are developing better and more sophisticated accounts of how it works, many deep questions remain. The present research examines some of these questions in relation to how memory can be decomposed into its component processes and how we are to understand these processes. An appropriate unde ....Are two processes one too many? An investigation of the viability of the dual-process model of recognition memory. Memory is the glue that holds together our lives and personal identities. While psychologists are developing better and more sophisticated accounts of how it works, many deep questions remain. The present research examines some of these questions in relation to how memory can be decomposed into its component processes and how we are to understand these processes. An appropriate understanding of these questions is vital to the development of interventions (both psychological and pharmacological) designed to halt or even reverse memory decline associated with normal aging and age-associated brain disease (such as Alzheimer disease).Read moreRead less
Ecophysiology of water-holding frogs in the Australian arid-zone. Water-holding frogs of arid-zone Australia have an Aboriginal heritage and cultural significance, but many aspects of their natural history, physiology and reproduction are poorly known or documented. We will examine behaviour, physiology, endocrinology, reproductive cycles and movements for these frogs (Cyclorana, Neobatrachus, Notaden, Heleioporus) while active on the surface, and cocoon formation, subterranean movements and dyn ....Ecophysiology of water-holding frogs in the Australian arid-zone. Water-holding frogs of arid-zone Australia have an Aboriginal heritage and cultural significance, but many aspects of their natural history, physiology and reproduction are poorly known or documented. We will examine behaviour, physiology, endocrinology, reproductive cycles and movements for these frogs (Cyclorana, Neobatrachus, Notaden, Heleioporus) while active on the surface, and cocoon formation, subterranean movements and dynamics of water exchange with the soil, metabolic depression, muscle ATP energetics, endocrinology and aspects of reproduction while aestivating underground. We have the expertise and prior experience to accomplish all aspects of the proposed studies.Read moreRead less
