Attentional and interpretive bias in anxiety: Concurrent expressions of a common selective mechanism, or independent mediators of anxiety vulnerability? The proposed research aims to determine whether two key cognitive biases recently shown to causally influence anxiety vulnerability, one involving selective attention to threat and the other involving the selective imposition of threatening interpretations on ambiguity, arise as concurrent manifestations of a common underlying causal mechanism, ....Attentional and interpretive bias in anxiety: Concurrent expressions of a common selective mechanism, or independent mediators of anxiety vulnerability? The proposed research aims to determine whether two key cognitive biases recently shown to causally influence anxiety vulnerability, one involving selective attention to threat and the other involving the selective imposition of threatening interpretations on ambiguity, arise as concurrent manifestations of a common underlying causal mechanism, or instead represent alternative causal pathways in the mediation of this emotional disposition. Resolution of this issue will significantly advance our theoretical understanding of the mechanisms that govern anxiety vulnerability, while also contributing directly to the development of new cognitive technologies designed to therapeutically modify such vulnerability.Read moreRead less
Integrating Models of Memory for Serial Order. This research aims to compare and integrate computational models of memory for serial order. The applicants have independently developed theoretically novel models, and this collaboration will enable them to combine and strengthen their complementary perspectives.

Existing models account ....Integrating Models of Memory for Serial Order. This research aims to compare and integrate computational models of memory for serial order. The applicants have independently developed theoretically novel models, and this collaboration will enable them to combine and strengthen their complementary perspectives.
Much psychologically important processing, for example speech perception and spelling, requires the representation and reproduction of serial order information. Existing models account for a wide range of data and collectively represent exciting progress in the understanding of basic mechanisms of memory. Can these models be unified and reconciled? To date, detailed comparisons of models are lacking. This proposal is for the applicants to elaborate and unify their contrasting theoretical approaches.

Aquatic eye design: sharks and rays as models of underwater colour and luminance vision. Sharks are usually assumed to be colour blind. We have discovered that they may in fact see colour very well and that the eyes of different species are adapted to their particular lifestyles. Our research will help to raise the profile of sharks and portray them as animals with advanced sensory systems and complex visual behaviours rather than just dangerous killing machines. Studying the vision of sharks m ....Aquatic eye design: sharks and rays as models of underwater colour and luminance vision. Sharks are usually assumed to be colour blind. We have discovered that they may in fact see colour very well and that the eyes of different species are adapted to their particular lifestyles. Our research will help to raise the profile of sharks and portray them as animals with advanced sensory systems and complex visual behaviours rather than just dangerous killing machines. Studying the vision of sharks may also help to reduce the number (currently >50,000) that are killed each year as bycatch by Australian long-line fisheries and make a valuable contribution to one of Australia's National Research Priorities (an Environmentally Sustainable Australia) for managing and conserving our biodiversity.Read moreRead less

The Big Australian Speech Corpus: An audio-visual speech corpus of Australian English. Contemporary speech science and technology are driven by the availability of large speech corpora. While audio databases exist for languages spoken in America, Europe and Japan, there is currently no large auditory-visual database of spoken language, and certainly not one for Australian English.

Contemporary speech science and technology are driven by the availability of large speech corpora. While audio databases exist for languages spoken in America, Europe and Japan, there is currently no large auditory-visual database of spoken language, and certainly not one for Australian English. Here we will establish the Big Australian Speech Corpus, which will support a speech science research and development using Australian English and facilitate the development of Australian speech technology applications from automatic speech recognition and text-to-speech synthesis used in taxi and other ordering services, to hearing prostheses and talking head aids for learning-impaired children, and a range of security and forensic applications.Read moreRead less
Maturation of the brain and the development of cognitive abilities. This project aims to develop techniques for measuring the growing brain. We will use these techniques to determine how the growing brain influences a child's intellectual ability and to answer an important question - do areas of the brain mature at the same or different rates and what influence does that have on the development of specific abilities such as language and reasoning? An answer to this question will make an import ....Maturation of the brain and the development of cognitive abilities. This project aims to develop techniques for measuring the growing brain. We will use these techniques to determine how the growing brain influences a child's intellectual ability and to answer an important question - do areas of the brain mature at the same or different rates and what influence does that have on the development of specific abilities such as language and reasoning? An answer to this question will make an important contribution to our theoretical understanding of developmental disorders. Moreover, given the influence of intellectual development on life prospects, it is important to understand how early brain development impacts on a child's ability to learn.Read moreRead less
Characterising and linking intermediate-level processing of pattern, motion and position in human vision? This work will advance basic science by enhancing understanding of human coding of image structure. The aim is to provide a common structure for understanding visual processing of form, motion and position. The work will help lift the international profile of Australian science.

This work will advance basic science by enhancing understanding of human coding of image structure. The aim is to provide a common structure for understanding visual processing of form, motion and position. The work will help lift the international profile of Australian science. Explaining how the primitives for shape perception are extracted will also have consequences of potential economic benefit. One important aspect is the design of displays that allow observers to absorb complex information about rapidly changing situations. This work has the potential to provide information that enables display designers to optimise the efficiency of presentation of pattern and motion information.Read moreRead less
Building Financial Literacy and Retirement Savings Engagement by Developing a Financial Education Programme for the Workplace.

To limit the drain on the federal budget as the population ages government have introduced compulsory superannuation; making individuals responsible for a significant proportion of their own retirement income. Employees are able to choose both their superannuation fund and investment mix. These are complex decisions which require a significant level of financial literacy. Failure to make appropriate decisions can significantly reduce wealth at retirement leading to a greater reliance on the age pension. Results from this project will inform government, employers and superannuation funds about the role of financial education in improving financial literacy and hence retirement savings decision making.Read moreRead less
Adaptive processes in normal and disordered face perception. Faces provide a wealth of social cues that guide interpersonal interactions, and most individuals are able to distinguish thousands of faces despite their perceptual similarity. This research investigates the foundations of these impressive face-perception skills and how they are disrupted in autism, a developmental disorder in which face perception is impaired. We focus on how the brain adaptively tailors its perceptual apparatus to ....Adaptive processes in normal and disordered face perception. Faces provide a wealth of social cues that guide interpersonal interactions, and most individuals are able to distinguish thousands of faces despite their perceptual similarity. This research investigates the foundations of these impressive face-perception skills and how they are disrupted in autism, a developmental disorder in which face perception is impaired. We focus on how the brain adaptively tailors its perceptual apparatus to interpret the structure of a face, for its identity, emotional content, and even intent. Uncovering how these processes function in normal and abnormal face perception could help develop effective interventions when these processes are disrupted in autism.Read moreRead less
The role of time and similarity in short-term memory. The project examines the role of time and similarity in memory for serial order, with the long-term goal to construct a new computational model of short-term memory.

The project examines the role of time and similarity in memory for serial order, with the long-term goal to construct a new computational model of short-term memory. The investigators are internationally known for their models, and the collaboration will enable them to combine their complementary perspectives into a unifying theory. Theory construction will be guided by two sets of studies: The first will delineate the circumstances, if any, under which temporal separation at encoding affects memory. So far, we have shown that temporal distinctiveness has no effect on memory, unless people use temporal gaps to 'chunk' the list. The second set of studies will examine whether phonological similarity determines the strength of encoding.Read moreRead less
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.

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
