Summary
Tackling facial prejudice. This project aims to investigate individual differences in facial prejudice, a powerful psychological bias whereby people rely on inaccurate first impressions to guide key decisions, such as whom to trust. Utilising recent advances in electrophysiology, the project will develop a new neural marker of individual differences in facial impressions that lead to prejudice. The project expects to lead to insights into the link between visual perception and social behaviour, ....Tackling facial prejudice. This project aims to investigate individual differences in facial prejudice, a powerful psychological bias whereby people rely on inaccurate first impressions to guide key decisions, such as whom to trust. Utilising recent advances in electrophysiology, the project will develop a new neural marker of individual differences in facial impressions that lead to prejudice. The project expects to lead to insights into the link between visual perception and social behaviour, and to develop strategies to reduce facial prejudice given the pervasive influence it has on everyday life.Read moreRead less
Determinants of Audio-Visual effects in degraded and non-degraded speech. Seeing a speaker's face can affect the perception of their speech in a number of ways. This project proposes a detailed comparison of factors that affect Audio-Visual (AV) facilitation of degraded speech detection and identification. Detection-based tasks should be more sensitive to signal based correlations whereas identification-based effects more sensitive to complementary information. The significance of the current pr ....Determinants of Audio-Visual effects in degraded and non-degraded speech. Seeing a speaker's face can affect the perception of their speech in a number of ways. This project proposes a detailed comparison of factors that affect Audio-Visual (AV) facilitation of degraded speech detection and identification. Detection-based tasks should be more sensitive to signal based correlations whereas identification-based effects more sensitive to complementary information. The significance of the current proposal is that it offers both a strategy and a connected series of experiments for determining key behavioural constraints on AV speech integration. Understanding AV interactions will build links between neurophysiological processes and coherent perception and have important implications for AV application.Read moreRead less
Who may judge a book by its cover? This project aims to build a model of how and why people vary in their impressions of others and in the accuracy of these impressions. People readily form impressions of others from their faces and these impressions influence crucial decisions: election results, court case outcomes and partner choices. To build this model, the project will apply twin data and construct a psychometric test to measure variation in facial impressions. The research is expected to l ....Who may judge a book by its cover? This project aims to build a model of how and why people vary in their impressions of others and in the accuracy of these impressions. People readily form impressions of others from their faces and these impressions influence crucial decisions: election results, court case outcomes and partner choices. To build this model, the project will apply twin data and construct a psychometric test to measure variation in facial impressions. The research is expected to lead to insights into this aspect of social perception, and to identify the sources of atypical or inaccurate facial judgements. This has applications in health contexts (to identify social impairment) and in security contexts (for personnel selection).Read moreRead less
Filters reveal what flicker conceals: temporal processing in the human visual system. I have recently discovered a new form of camouflage using 10Hz luminance flicker. This project will quantify this effect and examine the extent to which it generalises across colour and spatial dimensions and to video sequences depicting natural scenes. This information is expected to provide foundational information to technologies relating to national security that rely on visual concealment. This research wi ....Filters reveal what flicker conceals: temporal processing in the human visual system. I have recently discovered a new form of camouflage using 10Hz luminance flicker. This project will quantify this effect and examine the extent to which it generalises across colour and spatial dimensions and to video sequences depicting natural scenes. This information is expected to provide foundational information to technologies relating to national security that rely on visual concealment. This research will examine the extent to which filtering out these camouflaging frequencies enhances our sensitivity to low temporal frequency information. This decamouflaging aspect of my research is expected to improve the clarity of digital video-based technologies including ultrasound, educational, info-tainment and defence applicationsRead moreRead less
Exploring the brain mechanisms underlying hyperactivity in Attention-Deficit/Hyperactivity Disorder. Attention-deficit/Hyperactivity Disorder (AD/HD) is the most common psychiatric disorder affecting children, resulting in substantial costs (both human and financial) to the child, their family and Australian society.

Attention-deficit/Hyperactivity Disorder (AD/HD) is the most common psychiatric disorder affecting children, resulting in substantial costs (both human and financial) to the child, their family and Australian society. The outcomes of this project will provide a better foundation for understanding dysfunctional brain mechanisms in AD/HD, which is expected to lead to better diagnosis, treatment, and community support. Ultimately this will contribute to a healthy start to life for these children. This project will also demonstrate how an integrated Australian approach can lead the research agenda in both basic neuroscience, at the interface of psychology and physiology, and its applications in health.Read moreRead less
Central nervous system cytokines and morphine analgesia. Morphine remains the drug of choice for the management of moderate-to-severe pain, however its clinical effectiveness is compromised by the fact that morphine's analgesic (pain reducing) efficacy becomes less effective the more it is administered..

Morphine remains the drug of choice for the management of moderate-to-severe pain, however its clinical effectiveness is compromised by the fact that morphine's analgesic (pain reducing) efficacy becomes less effective the more it is administered.. This project will examine how analgesic tolerance develops from a completely new approach: Namely, how stimulation of the immune system within the central nervous system is a crucial factor in the development of tolerance. Modulation of analgesia by the immune system has not been systematically studied and provides a potentially fertile ground for the development of new techniques in the management of clinical pain.Read moreRead less

This project will study the effects of different housing conditions on neuroplasticity-related cognitive function by combining an innovative operant conditioning behavioural test (computerised touch-screen technology) and new molecular approaches. Potential gene-environment interactions will be revealed using genetically targeted mice which have never been assessed in that context (mutants with altered glucocorticoid and serotonin signalling). This project will study whether specific stages of the neuroplasticity process are differentially modulated through gene-environment interactions, ultimately resulting in changes to behaviour and cognitive functions. This will lead to a better understanding of the potential approaches that could be used to improve cognitive function.Read moreRead less
Validation of a New Conceptual Model of ADHD based on Underlying Central Nervous System Dysfunction. ADHD is a debilitating problem that affects 5% of children and approximately half as many adults. ADHD causes substantial problems at school and if untreated, predisposes the individual to increased drug and alcohol use, marital breakdown, criminal prosecution and psychiatric problems in later life. One problem is that we do not fully understand what are the causes of the disorder.

ADHD is a debilitating problem that affects 5% of children and approximately half as many adults. ADHD causes substantial problems at school and if untreated, predisposes the individual to increased drug and alcohol use, marital breakdown, criminal prosecution and psychiatric problems in later life. One problem is that we do not fully understand what are the causes of the disorder. This project will test the validity of several models of brain dysfunction in ADHD which have been influential in the literature, but poorly tested. Through better understanding of the basic underlying problems, more effective intervention can be developed.Read moreRead less

Repetitive transcranial magnetic stimulation (rTMS) is increasingly being used as a tool in studying human and animal brain function and in the treatment of brain disorders but there are fundamental gaps in our understanding of its basic mechanisms of action and hence our capacity to optimise protocols. This research will use near infrared spectroscopy to study the range of potential ways of altering brain activity with rTMS. It will substantially enhance the applicability of the technique ultimately improving our knowledge of human and animal brain function and outcomes for patients with depression and other disorders. It will help reinforce Australia as a leading country in the development of brain stimulation techniques.Read moreRead less
