In focusing on implicit cognitive processing of environmental food and eating cues, this project addresses a factor that has hitherto been neglected in obesity research. The inclusion of a component that specifically addresses food-related cognitions has the potential to dramatically improve the success of weight-loss programs. Accordingly, our research has clear potential benefit for Australian national health and well-being, consistent with Research Priority 2: Promoting and maintaining good health. It will also contribute to the international profile of Australian social science and provide valuable research training opportunities for students.

'Images of desire': An experimental cognitive approach to understanding and reducing food cravings. Food cravings are an important precursor to binge eating, a risk factor for both obesity and bulimia nervosa. Like many other Western countries, Australia has recently seen an alarming rise in these disorders. This project aims to investigate the imagery basis of food craving and develop effective techniques for its reduction. It has clear potential benefit for Australian national health and well- ....'Images of desire': An experimental cognitive approach to understanding and reducing food cravings.

Assessment of Executive Function in Children and Adults. This project aims to develop tests for executive function that are better grounded in the theory of cognitive processes, have sound measurement properties, and are more efficient, than existing measures. Executive functions entail planning, self-evaluation and adaptation to novel situations. Executive function deficits are found in children and adults who have suffered injury to the frontal regions of the brain, in some ageing adults, and ....Assessment of Executive Function in Children and Adults. This project aims to develop tests for executive function that are better grounded in the theory of cognitive processes, have sound measurement properties, and are more efficient, than existing measures. Executive functions entail planning, self-evaluation and adaptation to novel situations. Executive function deficits are found in children and adults who have suffered injury to the frontal regions of the brain, in some ageing adults, and in certain clinical groups such as autistics. Ability to cope with complexity is a factor in executive functioning, and this will be assessed utilising a new approach to analysis of cognitive complexity.Read moreRead less
Selective information processing and anxiety problems. Anxiety problems cost Australia over $1 billion per annum, and affect up to 16% of some Australian populations. Previous research by the applicants, and others, recently has established that certain patterns of selective information processing causally underpin elevated vulnerability to anxiety. The present program will serve to distinguish the functional contributions made by two specific classes of processing selectivity to two key dimensi ....Selective information processing and anxiety problems. Anxiety problems cost Australia over $1 billion per annum, and affect up to 16% of some Australian populations. Previous research by the applicants, and others, recently has established that certain patterns of selective information processing causally underpin elevated vulnerability to anxiety. The present program will serve to distinguish the functional contributions made by two specific classes of processing selectivity to two key dimensions of anxiety vulnerability. It is designed to produce novel cognitive technologies capable not only of predicting, but also of attenuating, both the tendency to experience anxiety reactions to stress, and the subsequent persistent of anxiety over time.Read moreRead less

Using eye movements to study how past experiences shape expectations. We intend to examine how the brain decides where to look next with our eyes, a decision made approximately three times every second. Understanding how the normal brain makes decisions will in turn help us to understand what happens when things go wrong in diseases like dementia and Parkinson's disease, with the hope of better - and earlier - diagnosis, and improved monitoring of treatment. In addition, our research will establ ....Using eye movements to study how past experiences shape expectations.

Understanding how the normal brain makes decisions will in turn help us to understand what happens when things go wrong in diseases like dementia and Parkinson's disease, with the hope of better - and earlier - diagnosis, and improved monitoring of treatment. In addition, our research will establish an important research link with The University of Cambridge, and allow Australia to be competitive with laboratories in North America and Europe that are currently studying how the brain makes decisions about where to look.Read moreRead less
Mechanisms of Recovery after Extinction of Conditioned Behaviour. Old habits die hard and may never die at all. My previous ARC-funded research has revealed that extinguished learning can be recovered rapidly and in unsuspected ways. This project is aimed at building a neural network to explain how old learning can recovered. In practical terms, rapid recovery has both benefits, e.g., our ability to regain old skills with brief refresher training, and costs, e.g., relapse after therapies for anx ....Mechanisms of Recovery after Extinction of Conditioned Behaviour. Old habits die hard and may never die at all. My previous ARC-funded research has revealed that extinguished learning can be recovered rapidly and in unsuspected ways. This project is aimed at building a neural network to explain how old learning can recovered. In practical terms, rapid recovery has both benefits, e.g., our ability to regain old skills with brief refresher training, and costs, e.g., relapse after therapies for anxiety disorders and substance abuse. In theoretical terms, understanding recovery in biological systems will inform research concerning both the neural basis of memory and the design of robots.Read moreRead less

Australia is a world leader in computational cognitive science, particularly with respect to language processing. This project will help maintain and extend this position. Insights from the project will help us understand the processes that underlie both normal reading and reading disorders, particularly in areas that are comparatively neglected yet extremely important, such as how people read words of more than one syllable. Given that everyone in Australian needs to learn to read and that acquired and developmental disorders of reading are common, providing the theoretical base on which the processes involved in reading can be understood (and hence learnt and remediated most effectively) is of utmost importance.Read moreRead less
Investigation of the component distributions of pause duration in spontaneous speech: Constraints for models of language production. We have discovered that the distribution of pause durations in spontaneous speech of individual speakers can be decomposed into at least two log-normal distributions. Our project will investigate this finding and provide a foundation for new research relevant to language production models. This will be achieved by determining the semantic, lexical, psycholinguistic ....Investigation of the component distributions of pause duration in spontaneous speech: Constraints for models of language production. We have discovered that the distribution of pause durations in spontaneous speech of individual speakers can be decomposed into at least two log-normal distributions. Our project will investigate this finding and provide a foundation for new research relevant to language production models. This will be achieved by determining the semantic, lexical, psycholinguistic, physiological, and acoustic concomitants of each component distribution and by investigating the impact of selected variables on the shape and location of each. The project has important implications for models of language production and applied problems involving automatic speech recognition, forensic speaker identification, and human communication disorders.Read moreRead less
Keeping track: The effect of distraction on attention to moving objects. This is basic research with broad societal implications. We constantly balance the attention demands of achieving a goal (e.g., driving) in the midst of competing environmental demands (e.g., attention-grabbing advertising).

This is basic research with broad societal implications. We constantly balance the attention demands of achieving a goal (e.g., driving) in the midst of competing environmental demands (e.g., attention-grabbing advertising). Billions of dollars are spent trying to make our roads safer, but basic research is critical to inform policy and design. There are three main benefits in identifying distractions that impair performance on a task that requires attention to moving objects. It will: (1) develop a method for exploring attention demands on real-world experiences (e.g., driving); (2) inform policy decisions on safer environments; and (3) provide a basis for minimising distractions in environments for people with attentional difficulties.Read moreRead less
