Investigating memory reliability in intoxicated witnesses of crime. Eyewitness testimony is a crucial piece of evidence for solving a crime. Inaccurate testimony leads to miscarriages of justice such as failed prosecutions or false convictions. Many witnesses and victims are affected by alcohol or other drugs during the crime. This project brings together a multidisciplinary team aiming to improve understanding of how intoxication with different substances affects the reliability of victim and w ....Investigating memory reliability in intoxicated witnesses of crime. Eyewitness testimony is a crucial piece of evidence for solving a crime. Inaccurate testimony leads to miscarriages of justice such as failed prosecutions or false convictions. Many witnesses and victims are affected by alcohol or other drugs during the crime. This project brings together a multidisciplinary team aiming to improve understanding of how intoxication with different substances affects the reliability of victim and witness memory accuracy. Crucially, crimes are frequently distressing; therefore the interaction between intoxication and stress urgently requires exploration. This project will significantly advance our understanding of key mechanisms behind drug effects on memory, and support fairer judicial outcomes for all. Read moreRead less
Determining principles for successful episode retrieval of repeated events. This project aims to develop the first-ever set of explanatory principles for how people successfully retain and retrieve individual episode memories from repeated experiences (e.g., one occurrence of a routine social encounter or job-related activity). By deepening our understanding of how memory works, this new knowledge is expected to lay the foundation for interview guidance and ongoing research aimed at enhancing th ....Determining principles for successful episode retrieval of repeated events. This project aims to develop the first-ever set of explanatory principles for how people successfully retain and retrieve individual episode memories from repeated experiences (e.g., one occurrence of a routine social encounter or job-related activity). By deepening our understanding of how memory works, this new knowledge is expected to lay the foundation for interview guidance and ongoing research aimed at enhancing the proficiency of investigations into matters that rely on detailed and accurate accounts of specific episodes. This includes workplace or traffic accident investigations, infectious disease contact tracing, as well as prosecution of repeated sexual offences.Read moreRead less
Threshold Decisions in Determining Whether to Prosecute Child Sexual Abuse. The objective of this project is new knowledge about the way police and prosecutors make decisions about the prosecution of child sexual assault that could be used to influence policy and practice. Few cases of child sexual abuse reported to the police ever go to court but recent research in New South Wales for the Royal Commission indicates that the proportion has declined sharply over the last decade or so. This projec ....Threshold Decisions in Determining Whether to Prosecute Child Sexual Abuse. The objective of this project is new knowledge about the way police and prosecutors make decisions about the prosecution of child sexual assault that could be used to influence policy and practice. Few cases of child sexual abuse reported to the police ever go to court but recent research in New South Wales for the Royal Commission indicates that the proportion has declined sharply over the last decade or so. This project aims to examine how police and prosecutors decide which cases proceed and why, and how they confer with each other as well as when and how they consult with complainants and their families. This project plans to also develop and test practice tools and principles for police and prosecutors with expected benefits for both them and the families involved.Read moreRead less
Judges' work, place and psychological health - a national view. This project aims to address the human, juridical and financial costs of judicial officers’ work-related psychological harm. This harm is implicated in early retirement, sick leave and suicide. It threatens appropriate courtroom conduct, procedural fairness and impartial adjudication. The project seeks to generate new knowledge of the stress judicial officers experience and the individual and institutional mechanisms for managing st ....Judges' work, place and psychological health - a national view. This project aims to address the human, juridical and financial costs of judicial officers’ work-related psychological harm. This harm is implicated in early retirement, sick leave and suicide. It threatens appropriate courtroom conduct, procedural fairness and impartial adjudication. The project seeks to generate new knowledge of the stress judicial officers experience and the individual and institutional mechanisms for managing stressors, combining socio-legal and psychological approaches. Expected outcomes include evidence-based understandings to inform recruitment and retention strategies specific to this highly specialized workforce. This should provide significant benefits for judges’ work capacities and courts' delivery of justice.Read moreRead less
Body Worn Camera Evidence and Assessment of Witness Credibility. The aim of this project is to establish how the use of Body Worn Cameras to record statements in domestic and family violence cases affects assessment of a complainant’s credibility at trial. It will generate new knowledge about the influence of: (i) the physical environment in which recordings are made, (ii) the audio and visual quality of recordings, and (iii) fact-finders’ (judges and jurors) emotional responses to recordings.

Improving the diagnosticity of eyewitness memory choices. Eyewitness identification error is common and costly. This project aims to improve the quality of information provided by eyewitnesses, and the ability of police officers and triers of fact (e.g., juries, judges) to evaluate this information. Laboratory investigations will determine how best to test memory and confidence to achieve this aim. A new class of cognitive models will provide a unified account of response accuracy, response time ....Improving the diagnosticity of eyewitness memory choices. Eyewitness identification error is common and costly. This project aims to improve the quality of information provided by eyewitnesses, and the ability of police officers and triers of fact (e.g., juries, judges) to evaluate this information. Laboratory investigations will determine how best to test memory and confidence to achieve this aim. A new class of cognitive models will provide a unified account of response accuracy, response time, and confidence, suitable for application to computerized testing scenarios. The models and testing methods validated in the laboratory will be refined for application in eyewitness memory settings, facilitating better evaluation of identification evidence, and potentially reducing wrongful convictions.Read moreRead less
Linking arterial, brain and cognitive integrity in healthy older adults. This project aims to demonstrate that engaging the brain’s prefrontal cortex, an area that is highly sensitive to ageing, can improve the function of arteries that supply blood to this brain region.

This project aims to demonstrate that engaging the brain’s prefrontal cortex, an area that is highly sensitive to ageing, can improve the function of arteries that supply blood to this brain region. Using an innovative optical imaging methodology that maps the brain’s regional arterial health, it aims to generate new knowledge about the link between this arterial system and the progressive decline in cognitive control ability and in prefrontal cortex structure and function in healthy older adults. This interdisciplinary, international collaboration aims to put Australia at the forefront of brain optical imaging methods that may have significant benefits by informing approaches to promote and maintain healthy brain and cognition in old age.Read moreRead less
Effort and reward valuation. This project aims to examine the relationships between effort, value, and life satisfaction. Effort, which is closely akin to motivation, is influenced by several variables. The project will reveal the psychological variables that cause effort to have a positive as well as a negative influence on reward valuation. This will help to understand how, when, and why effort influences motivation, and how these processes may encourage healthier, more productive choices, and ....Effort and reward valuation.

Extinction of conditioned responding: Learning from the evidence of absence. When animals or people learn that a cue, or their own action, is followed by something important, they respond in anticipation of the outcome or to control it. This project investigates how these learned responses can be reduced (“extinguished”) when the conditions that established them change. It will help solve 2 outstanding theoretical and practical problems: what makes some learned behaviours resistant to extinction ....Extinction of conditioned responding: Learning from the evidence of absence. When animals or people learn that a cue, or their own action, is followed by something important, they respond in anticipation of the outcome or to control it. This project investigates how these learned responses can be reduced (“extinguished”) when the conditions that established them change. It will help solve 2 outstanding theoretical and practical problems: what makes some learned behaviours resistant to extinction or prone to relapse after being extinguished? The project will identify the factors that are most directly responsible for resistance and relapse. This could pave the way to finding solutions for the major problems that bedevil therapies designed to treat human behavioural disorders, such as addictions, gambling, and anxietyRead moreRead less
Extinction and response inhibition. Humans and other animals readily learn to perform an action if it is “reinforced” by a reward and will extinguish the action if it stops being reinforced. Popular models of learning describe extinction as the automatic outcome of a prediction-error correction process that gradually weakens, and eventually eliminates, the response-reward association. But there is much evidence that conditioned responses are not eliminated and can be quickly restored. Other evid ....Extinction and response inhibition. Humans and other animals readily learn to perform an action if it is “reinforced” by a reward and will extinguish the action if it stops being reinforced. Popular models of learning describe extinction as the automatic outcome of a prediction-error correction process that gradually weakens, and eventually eliminates, the response-reward association. But there is much evidence that conditioned responses are not eliminated and can be quickly restored. Other evidence suggests that extinction might involve more specific inhibitory processes that suppress the response without eliminating the original learning. The current project investigates the role of response inhibition in the extinction of learned responses in humans.Read moreRead less
