Impacts of diet on the brain, body, and microbiome. Dietary habits determine cognitive function, metabolism and the composition of the gut microbiome. This project seeks to clarify the role of the gut microbiome in diet-induced changes to cognition. It aims to do so through longitudinal studies of cognitive function in which dietary patterns are systematically varied, and intervention studies where cognition is tested after experimentally manipulating the gut microbiome. Expected outcomes inclu ....Impacts of diet on the brain, body, and microbiome. Dietary habits determine cognitive function, metabolism and the composition of the gut microbiome. This project seeks to clarify the role of the gut microbiome in diet-induced changes to cognition. It aims to do so through longitudinal studies of cognitive function in which dietary patterns are systematically varied, and intervention studies where cognition is tested after experimentally manipulating the gut microbiome. Expected outcomes include new interdisciplinary knowledge spanning psychology, neuroscience, nutrition and metabolism. This project is timely given the enormous shifts in Australian dietary choices. The knowledge to be gained should provide benefits to individual and public health, agriculture, and food systems.Read moreRead less
Defensive behaviours elicited by predator odours. Rats display a powerful anxiety responses when confronted with the odours of predators such as cats. This response may occur even though rats have never encountered an actual predator before. This project aims to investigate the nature of this anxiety and the nature of the stimuli that produce it. The outcomes should be a better understanding of the neural basis and pharmacology of anxiety states and the identification of novel chemicals that hav ....Defensive behaviours elicited by predator odours. Rats display a powerful anxiety responses when confronted with the odours of predators such as cats. This response may occur even though rats have never encountered an actual predator before. This project aims to investigate the nature of this anxiety and the nature of the stimuli that produce it. The outcomes should be a better understanding of the neural basis and pharmacology of anxiety states and the identification of novel chemicals that have powerful rodent repellent properties. Such chemicals may be of great use in domestic and agricultural contexts where rodents are pests.Read moreRead less
Determining the role of neuronal nicotinic acetylcholine receptor subunits in the development of addictive behaviours. The economic and health burden of substance abuse in Australia exceeds $31.5 billion and there are currently few treatment options. Nicotinic receptors (nAChRs) are a common target for the interaction of alcohol and nicotine in the brain. This project aims to determine the role of nAChRs in the development of addiction to alcohol and nicotine.

Summary
Unravelling the relationship between food and the brain. This project aims to investigate how highly palatable foods that are high in fat and sugar, interact with the brain to cause their overconsumption. Highly palatable foods cause plasticity in brain reward circuitry in a manner similar to drugs of abuse. Identifying how these "junk" foods interact with reward areas of the brain will explore the neural mechanisms underlying the hedonic nature of appetite. This project will not only inform our ....Unravelling the relationship between food and the brain. This project aims to investigate how highly palatable foods that are high in fat and sugar, interact with the brain to cause their overconsumption. Highly palatable foods cause plasticity in brain reward circuitry in a manner similar to drugs of abuse. Identifying how these "junk" foods interact with reward areas of the brain will explore the neural mechanisms underlying the hedonic nature of appetite. This project will not only inform our understanding of how exposure to these foods can contribute to overeating and obesity, a huge and growing problem in Australia, but will also provide evidence to inform policy options relevant to advertising and marketing of these foods.Read moreRead less
When immigrants and converts are not truly one of us: Examining the social psychology and developmental antecedents of marginalizing racism. Marginalizing Racism, the simultaneous acceptance and rejection of others, is clearly present in Australia. It is not just a matter of thugs on the streets of Cronulla, but of elected politicians expressing Marginalizing Racist views. We believe that examining the social psychology and developmental causes of this insidious form of racism will pave the way ....When immigrants and converts are not truly one of us: Examining the social psychology and developmental antecedents of marginalizing racism. Marginalizing Racism, the simultaneous acceptance and rejection of others, is clearly present in Australia. It is not just a matter of thugs on the streets of Cronulla, but of elected politicians expressing Marginalizing Racist views. We believe that examining the social psychology and developmental causes of this insidious form of racism will pave the way for positive social change. This is not just an academic exercise, but a chance to expose and tackle a form of racism to which the broader public and our own profession appears to turn a blind eye. Moreover, as we expect this research to yield timely and influential discoveries, it will help maintain Australia's position as a world leader in the field of social psychology.Read moreRead less
Captions for the Deaf and Hearing Impaired: Availability versus Accessibility. The availability of educational, informational and recreational services for deaf and hearing-impaired people has been dramatically facilitated by (i) increased television captioning due to the 2001 introduction of the Television Broadcasting Services Act; and (ii) trial introduction of real-time captioning in educational settings. These innovations must be matched by equally innovative ways of increasing the accessib ....Captions for the Deaf and Hearing Impaired: Availability versus Accessibility. The availability of educational, informational and recreational services for deaf and hearing-impaired people has been dramatically facilitated by (i) increased television captioning due to the 2001 introduction of the Television Broadcasting Services Act; and (ii) trial introduction of real-time captioning in educational settings. These innovations must be matched by equally innovative ways of increasing the accessibility of captions, which is currently limited by English literacy, caption speed, and caption reduction techniques. Here, systematic manipulation of these factors in experiments on television captioning with adults and educational captioning with children will determine how resources might best be directed to improving caption accessibility.Read moreRead less
Children's Intergroup Prejudice: The Roles of Cognitive Representations and Self-presentation. Research indicates that intergroup prejudice remains a problem in most Australian schools. For example, children as young as 5-6 years assign negative attributes to indigenous Australians and Pacific Islander children, they prefer not to play with these children, and they do not even want them living nearby. The proposed research will examine the possible basis of age effects in these attitudes. It wi ....Children's Intergroup Prejudice: The Roles of Cognitive Representations and Self-presentation. Research indicates that intergroup prejudice remains a problem in most Australian schools. For example, children as young as 5-6 years assign negative attributes to indigenous Australians and Pacific Islander children, they prefer not to play with these children, and they do not even want them living nearby. The proposed research will examine the possible basis of age effects in these attitudes. It will have a substantial national benefit because it will increase our understanding of this insidious social phenomenon and provide a basis for developing an intervention that will minimise a problem that has the potential to devastate community relations.

Rejection sensitivity in children and adolescents: Antecedents, consequences, and the promotion of rejection resilience. Increasing our understanding of children's rejection sensitivity and its effects, as well as identifying the central processes involved, will contribute to a healthy start, preventative healthcare, and strengthening social and economic fabric. It will allow for a new intervention to build children's competencies, coping and resilience. This will protect from negative intrapers ....Rejection sensitivity in children and adolescents: Antecedents, consequences, and the promotion of rejection resilience. Increasing our understanding of children's rejection sensitivity and its effects, as well as identifying the central processes involved, will contribute to a healthy start, preventative healthcare, and strengthening social and economic fabric. It will allow for a new intervention to build children's competencies, coping and resilience. This will protect from negative intrapersonal (e.g., depression) and interpersonal outcomes (e.g., loneliness, victimisation). It also will improve the social and learning contexts for students, benefit the environment in which teachers work, and strengthen the fabric of families and communities by contributing to the development of harmonious, cooperative environments.Read moreRead less

This project aims to investigate the psychological and social effects of having missing family on forcibly displaced people settled in Australia. This world-first project enlists a longitudinal mixed-method approach to compare those with missing family to those whose connections have been restored on key outcomes and coping strategies. Project outcomes will enhance the ability of Australian Red Cross and the International Committee of the Red Cross to understand and support the needs of families of the missing. This should provide significant practice and policy benefits for Red Cross’ humanitarian work in restoring family links in Australia and worldwide.Read moreRead less
Peer Rejection and the Maladaptive Social Behaviour of Children and Adolescents. Research indicates that peer rejection has serious negative effects on child and adolescent victims. However, little research has addressed the likelihood that peer rejection also has negative consequences for others in the social environment, through its instigation of maladaptive social behaviours such as bullying and ethnic prejudice. Given the incidence of the latter behaviours in primary and secondary schools, ....Peer Rejection and the Maladaptive Social Behaviour of Children and Adolescents. Research indicates that peer rejection has serious negative effects on child and adolescent victims. However, little research has addressed the likelihood that peer rejection also has negative consequences for others in the social environment, through its instigation of maladaptive social behaviours such as bullying and ethnic prejudice. Given the incidence of the latter behaviours in primary and secondary schools, the aim of this project is to conduct a program of research to test an integrative model of the impact of peer rejection on the maladaptive social behaviours of children and adolescents, with a particular focus on ethnic prejudice and bullying.Read moreRead less
