Implicit cognitive processing of environmental food and eating cues in obese adults. Obesity is a major public health concern in Western countries, including Australia. 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. A ....Implicit cognitive processing of environmental food and eating cues in obese adults. Obesity is a major public health concern in Western countries, including Australia. 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.

Square Eyes or All Lies? Understanding Children's Exposure to Screens. This project will examine Australian parents’ number one concern about their children’s health and behaviour – their interactions with electronic screens. Current screen time guidelines are based on low-quality evidence and lack the nuance required to address this complex issue. This project will use innovative technology to resolve these weaknesses. Wearable cameras will measure what children are doing on screens, and where, ....Square Eyes or All Lies? Understanding Children's Exposure to Screens. This project will examine Australian parents’ number one concern about their children’s health and behaviour – their interactions with electronic screens. Current screen time guidelines are based on low-quality evidence and lack the nuance required to address this complex issue. This project will use innovative technology to resolve these weaknesses. Wearable cameras will measure what children are doing on screens, and where, when, and how long they are doing it. The project will also investigate how screen time impacts children’s development and how it is influenced by their environment. This evidence will benefit children by improving screen time guidelines, and help parents understand the impact of screen time on children’s development.

Things don’t always go better with Coke. This project aims to test whether soft drink use is governed partly by automatic processes (cognitive biases) that operate largely outside of conscious control. In so doing, the project expects to generate a new conceptual understanding of the mechanisms that drive the overconsumption of soft drinks. Expected outcomes include theoretical innovation, new research methodologies, and accessible cost-effective technologies for reducing excessive sugar intake ....Things don’t always go better with Coke. This project aims to test whether soft drink use is governed partly by automatic processes (cognitive biases) that operate largely outside of conscious control. In so doing, the project expects to generate a new conceptual understanding of the mechanisms that drive the overconsumption of soft drinks. Expected outcomes include theoretical innovation, new research methodologies, and accessible cost-effective technologies for reducing excessive sugar intake from soft drinks, in line with recent World Health Organization guidelines. These outcomes will contribute to combatting obesity and tooth decay.Read moreRead less
The biological origins underpinning adolescent sleep timing. Notwithstanding cultural and social influences, bedtimes gradually become later during adolescence, suggesting common biological contributions. Reductions in sleep pressure, delays in the 24-hour circadian rhythm, and genetic associations have been implicated, yet comprehensive prospective data from these biological sleep processes are lacking. This project aims to use periodic 'in-lab' assessments to unmask young adolescents' circadia ....The biological origins underpinning adolescent sleep timing. Notwithstanding cultural and social influences, bedtimes gradually become later during adolescence, suggesting common biological contributions. Reductions in sleep pressure, delays in the 24-hour circadian rhythm, and genetic associations have been implicated, yet comprehensive prospective data from these biological sleep processes are lacking. This project aims to use periodic 'in-lab' assessments to unmask young adolescents' circadian rhythm delay and sleep pressure which may predict naturalistic sleep behaviour in their home environment. It is predicted that adolescents who show both low sleep pressure and later circadian delay to possess later bedtimes, thus enhancing knowledge of covert biological mechanisms sabotaging healthy adolescent sleep.Read moreRead less
A formal signal detection model of eyewitness identification. The project aims to aid in producing better procedures for the collection and assessment of eyewitness identification evidence. In a police line-up, a witness is asked to identify a perpetrator from a group of similar individuals. Applied research has focused on conditions that optimise witness performance but many of the conclusions from this research have been challenged on the basis that they use inappropriate measures of performan ....A formal signal detection model of eyewitness identification. The project aims to aid in producing better procedures for the collection and assessment of eyewitness identification evidence. In a police line-up, a witness is asked to identify a perpetrator from a group of similar individuals. Applied research has focused on conditions that optimise witness performance but many of the conclusions from this research have been challenged on the basis that they use inappropriate measures of performance. Recent work has highlighted the usefulness of analyses based on the theory of signal detection. However, the line-up task does not fit easily within standard signal detection paradigms as it combines two tasks; detection and identification. The project aims to understand how these components work in order to measure witness performance.Read moreRead less
Problematic interactions between autistic adults and the justice system. This project aims to highlight how autistic adults may fall foul of the law due to a diminished ability to recognise subtle cues in social interactions that should warn of unfolding criminal activity or deteriorating relationships with justice system personnel. Autism Spectrum Disorder has unique characteristics that may lead to unwitting involvement in crime and problematic interactions with the justice system. This projec ....Problematic interactions between autistic adults and the justice system. This project aims to highlight how autistic adults may fall foul of the law due to a diminished ability to recognise subtle cues in social interactions that should warn of unfolding criminal activity or deteriorating relationships with justice system personnel. Autism Spectrum Disorder has unique characteristics that may lead to unwitting involvement in crime and problematic interactions with the justice system. This project expects to unveil innovative research paradigms, establish a knowledge base for police and the courts, and assist in developing guidelines for remediating misunderstandings that contribute to problematic interactions with the justice system.Read moreRead less
Uncovering the processes underlying human category learning. There is a pervasive belief that complex tasks can somehow be learned via a 'smart' implicit or procedural learning mechanism, which operates independently of memory and attention. This idea has important implications for our understanding of cognition. If true, there seems little point in providing explicit instruction in such tasks, and efforts to do so are, at best, wasted time and, at worst, detrimental to the learning process. Th ....Uncovering the processes underlying human category learning. There is a pervasive belief that complex tasks can somehow be learned via a 'smart' implicit or procedural learning mechanism, which operates independently of memory and attention. This idea has important implications for our understanding of cognition. If true, there seems little point in providing explicit instruction in such tasks, and efforts to do so are, at best, wasted time and, at worst, detrimental to the learning process. This project will provide much-needed scrutiny of this idea and will help not only to re-orient our understanding of how we deal with complex information, but will also highlight issues about data interpretation that are fundamental for the research and wider communities.Read moreRead less
Can attentional re-training reduce food cravings and consumption? This project aims to determine the impact of a procedure involving the re-training of attention to food cues on food cravings and food intake. Results will advance our understanding of food cravings and contribute to interventions aimed at curbing unwanted cravings and (over) consumption.
