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
Do Exposures Before Conception Influence The Risk Of Asthma In Offspring?

Summary
Asthma and poor lung function are major causes of public health issues. Emerging evidence suggests adverse exposures even before the conception of a child may cause these conditions. The proposed project is part of an international study across generations to identify these factors. This study will provide novel evidence to guide interventions and identify studies to advance this area further. These original findings will be of great importance both nationally and internationally.
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
Understanding And Overcoming Cardiovascular And Diabetes Inequalities In Indigenous Australians

Summary
Aboriginal and Torres Strait Islanders experience the highest rates of heart disease and diabetes of all Australians. The reasons for this large disparity is not yet fully understood. I propose to investigate the patterns, causes, complications and links between heart disease and diabetes in Indigenous populations to identify better ways of managing and preventing chronic disease in high risk communities.
Maintaining a precise, invariant unit in state, national and international educational assessment. School achievement testing is a high stakes activity for state and national governments, not just for school students. Significant educational policy decisions turn on comparisons of test results over time, and among states and nations. These decisions rest on assumptions about the validity and precision of national testing. In particular, current measurement systems assume that assessment scales h ....Maintaining a precise, invariant unit in state, national and international educational assessment. School achievement testing is a high stakes activity for state and national governments, not just for school students. Significant educational policy decisions turn on comparisons of test results over time, and among states and nations. These decisions rest on assumptions about the validity and precision of national testing. In particular, current measurement systems assume that assessment scales have common units. Empirically, it is clear that many factors can compromise this assumption, making it rarely justified. This study will serve the national interest by building the theory and technology necessary to solve this problem.Read moreRead less
Maintaining invariant scales in state, national and international level assessments. Large scale assessments involve comparisons between countries, states within a country, and within these over time. For many reasons, identical items cannot be administered to every student. Nevertheless, the items must operate invariantly across groups. The Rasch models, which have invariance as an intrinsic property, are powerful in checking for such invariance. This project brings the basic research of the ....Maintaining invariant scales in state, national and international level assessments. Large scale assessments involve comparisons between countries, states within a country, and within these over time. For many reasons, identical items cannot be administered to every student. Nevertheless, the items must operate invariantly across groups. The Rasch models, which have invariance as an intrinsic property, are powerful in checking for such invariance. This project brings the basic research of the Chief Investigators to the industry partners to study, apply and document ways in which violations of Rasch models and different data collection formats are reflected as changes of scale, and how these might be controlled both statistically and empirically.Read moreRead less
Young Adult Myopia: Genetic And Environmental Associations

Funding Amount
$809,271.00
Summary
Myopia affects 80% of school leavers in the cities of East Asia, 45% of Asian Australian school leavers and is probably on the rise in European Australian adolescents. Increased levels of education and lack of time outdoors are known to increase the risk of myopia. We will examine 2,000 young adults to find the genes that interact with these risk factors. In addition to confirming when these risk factors are most important, identifying molecular pathways opens the avenue of new treatments.
Identifying Glaucoma Risk Variants In The Norfolk Island Genetic Isolate

Summary
Primary open angle glaucoma is the most common form of glaucoma. In this project we will focus on the identification of functional genetic variants influencing development of this disorder, using a powerful whole exome sequencing approach in a large multigenerational pedigree from the Norfolk Island population isolate. The identification of genes influencing glaucoma development would provide invaluable clues to aid in defining the pathophysiology of this common disease.
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
