How we remember and misremember traumatic experiences. The project addresses a significant and important problem: the role of memory distortion in Post Traumatic Stress Disorder (PTSD), a global disorder with significant personal, societal and economic costs. The aim of this project is to empirically investigate the extent, causes and triggering conditions of errors in memory for traumatic experiences; particularly exaggeration of these memories, which has been linked to poor psychological adjus ....How we remember and misremember traumatic experiences. The project addresses a significant and important problem: the role of memory distortion in Post Traumatic Stress Disorder (PTSD), a global disorder with significant personal, societal and economic costs. The aim of this project is to empirically investigate the extent, causes and triggering conditions of errors in memory for traumatic experiences; particularly exaggeration of these memories, which has been linked to poor psychological adjustment. Understanding how people exposed to trauma remember, and misremember, aspects of their experiences in ways that influence their recovery is both theoretically and practically important. Indeed, it will help us refine theory and identify possible points of intervention for PTSD sufferers.Read moreRead less

Advancing cross-cultural approaches to violence risk assessment. This project aims to evaluate the usefulness of violence risk instruments for Australian Indigenous and Culturally and Linguistically Diverse individuals who have contact with the justice system. Violence risk assessment is undertaken to estimate an individual’s risk for future violence. Instruments are widely used in Australian medico-legal and correctional settings to inform sentencing, treatment planning and offender management ....Advancing cross-cultural approaches to violence risk assessment. This project aims to evaluate the usefulness of violence risk instruments for Australian Indigenous and Culturally and Linguistically Diverse individuals who have contact with the justice system. Violence risk assessment is undertaken to estimate an individual’s risk for future violence. Instruments are widely used in Australian medico-legal and correctional settings to inform sentencing, treatment planning and offender management strategies. However their predictive validity and utility for Australians from diverse cultural backgrounds is unclear. An analysis of both existing assessment and new qualitative data is expected to produce findings that can contribute to improved violence risk assessment and the enhanced prevention and management of violence.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
The role of reward expectancy and reward availability in appetitive motivation. This project will investigate the learning processes that help regulate our desire for rewards such as food and drugs and our decisions about when to pursue those rewards. The results will have implications for our understanding of normal reward motivation as well as interventions for maladaptive behaviours such as gambling and drug-taking.
Do family environments influence children's brain development during the transition to adolescence? Late childhood marks the first stages of a wave of brain growth and reorganisation, second only to infancy in terms of its extent and significance. This project will investigate whether brain development during this period is affected by parenting behaviours, which will ultimately inform early intervention and prevention efforts.
Attributions for food intake and the control of eating. When explaining why they ate as much as they did in a particular situation, people generally overestimate the role of their hunger or the taste of the food, and underestimate the impact of other factors such as how much food they are served or how much other people eat. This project will examine the motivation behind these mis-attributions, and will also examine the behavioural and emotional consequences of the attributions people make for ....Attributions for food intake and the control of eating. When explaining why they ate as much as they did in a particular situation, people generally overestimate the role of their hunger or the taste of the food, and underestimate the impact of other factors such as how much food they are served or how much other people eat. This project will examine the motivation behind these mis-attributions, and will also examine the behavioural and emotional consequences of the attributions people make for their food intake. By doing so, the proposed research will make a significant contribution to the theoretical understanding of people’s food intake, and can also have practical implications for helping people appropriately regulate their food intake.Read moreRead less
How do social and environmental cues influence food intake? This project will determine how social and environmental factors influence how much people eat. These insights will have theoretical implications for our understanding of what drives people's food intake, and will have practical implications for interventions aimed at curbing excess energy intake, weight gain, and obesity.

This project aims to increase our understanding of what aspects of websites encourage people to engage in risky behaviours. Risk taking in online environments can have significant negative consequences, such as being a victim or perpetrator of cybercrime. This project aims to develop and test a conceptual model to understand the psychological processes underlying risk taking online, focusing on the impact of social cues and specific online environmental cues. Anticipated project outcomes will benefit policy-makers by identifying how sites can be made safer and may also show how to educate people to make safe decisions online and to avoid sites that may encourage them to take risks or engage in anti-social behaviours.Read moreRead less

Does obesity alter the associations to food related cues, contexts and responses? Obesity is increasing dramatically in the developed world. The reasons for this are unclear, however the abundance of cheap, palatable food is clearly a contributing factor. Studies suggest differences arise in the processing of food rewards between overweight and lean individuals and the way they respond to food associated cues. This indicates that food associated cues may be more likely to evoke feeding behaviour ....Does obesity alter the associations to food related cues, contexts and responses? Obesity is increasing dramatically in the developed world. The reasons for this are unclear, however the abundance of cheap, palatable food is clearly a contributing factor. Studies suggest differences arise in the processing of food rewards between overweight and lean individuals and the way they respond to food associated cues. This indicates that food associated cues may be more likely to evoke feeding behaviours in absence of metabolic needs, therefore contributing to over eating that leads to obesity. This project will determine how rats, exposed to a model of our obesogenic western diet, process distinct cues and contexts associated with food rewards and control value driven responses to gain food rewards.Read moreRead less
Uncertainty and response control in the prefrontal cortex. This project will identify how complex behaviours come to be performed habitually. It is proposed that statistical certainty in the learning environment is a key determinant of automatic behaviour, that detection of uncertainty can restore voluntary control of behaviour and that this is an important function of the prefrontal cortex of the brain.
