Single and dual process models of recognition memory: Reconciliation of behavioural, electrophysiological, and neuroimaging data. Advanced brain scanning technologies are increasingly used to study human memory. As well as being important for our basic understanding of memory, they also tell us how memory is affected by normal development, ageing, disease, and injury. Unfortunately, because these technologies are so new, a gap has opened up between our psychological understanding of memory and t ....Single and dual process models of recognition memory: Reconciliation of behavioural, electrophysiological, and neuroimaging data. Advanced brain scanning technologies are increasingly used to study human memory. As well as being important for our basic understanding of memory, they also tell us how memory is affected by normal development, ageing, disease, and injury. Unfortunately, because these technologies are so new, a gap has opened up between our psychological understanding of memory and the physiological events measured by the scanning technologies. This has created a problem for how we should interpret the results that are found. The present project aims to close this gap by applying new research methodologies and theoretical insights based on our previous research.Read moreRead less
How we recognise the orientation of objects: a combined neurophyschological / eye movement study. Neurophyschological evidence suggests that different visual attributes of objects (e.g. shape vs orientation in space) are processed by independent brain systems. This project aims to investigate this issue systematically, using both neurological patients and normal volunteers. By using sensitive experimental measures, including detailed analyses of subject's eye movements while they view objects, ....How we recognise the orientation of objects: a combined neurophyschological / eye movement study.

This project aims to investigate this issue systematically, using both neurological patients and normal volunteers. By using sensitive experimental measures, including detailed analyses of subject's eye movements while they view objects, this research will provide valuable insights into how the visual system gathers and encodes information about different object attributes.Read moreRead less

Charitable triad: How donors, beneficiaries, & fundraisers influence giving. This project aims to test a new model of charitable giving to examine how donors, beneficiaries, and fundraisers together influence donor decisions. Until now, no holistic model has existed to explain donor behaviour: past research has focused on donors but neglected beneficiaries and fundraisers. This project is expected to provide evidence for a new bedrock theory of philanthropy. Findings can also inform practitioner ....Charitable triad: How donors, beneficiaries, & fundraisers influence giving. This project aims to test a new model of charitable giving to examine how donors, beneficiaries, and fundraisers together influence donor decisions. Until now, no holistic model has existed to explain donor behaviour: past research has focused on donors but neglected beneficiaries and fundraisers. This project is expected to provide evidence for a new bedrock theory of philanthropy. Findings can also inform practitioner toolkits, offering advice to nonprofits on how to raise money effectively by understanding how the particular organisation and its beneficiaries can influence donor decisions. By helping ensure the survival of charities, this research will contribute to the delivery of essential social services that benefit many Australians.Read moreRead less
Evidence-based improvement of statistical inference practices in psychology and other disciplines. The commonest ways that many researchers currently draw conclusions from their data have been shown to be inefficient, and often used incorrectly. This project will develop new, better statistical representations and software tools for data analysis. It will evaluate and demonstrate the effectiveness of these. Wide adoption of these techniques and tools will enhance the international reputation ....Evidence-based improvement of statistical inference practices in psychology and other disciplines. The commonest ways that many researchers currently draw conclusions from their data have been shown to be inefficient, and often used incorrectly. This project will develop new, better statistical representations and software tools for data analysis. It will evaluate and demonstrate the effectiveness of these. Wide adoption of these techniques and tools will enhance the international reputation and competitiveness of Australian psychological science. Adoption by Australian researchers across the social and behavioural sciences, and in other disciplines including medicine, economics and ecology, will improve the efficiency and effectiveness of Australian research, with consequential wide-ranging benefits to the Australian community.Read moreRead less
Celebrate. Remember. Fight Back. Episodic Volunteering for Non-Profits. This project seeks to improve the policy and practice of volunteer involvement in the non-profit sector. Non-profit organisations rely on volunteers, and their capacity to deliver vital community services is threatened by the decrease in long-term, continuous volunteering and increase in episodic (short-term, flexible) volunteering.

This project seeks to improve the policy and practice of volunteer involvement in the non-profit sector. Non-profit organisations rely on volunteers, and their capacity to deliver vital community services is threatened by the decrease in long-term, continuous volunteering and increase in episodic (short-term, flexible) volunteering. The interdisciplinary project aims to use mixed methods (qualitative interviews and quantitative surveys) and multiple perspectives (volunteers and staff who manage them) to develop an episodic volunteering definition; to explore the economic and social impact of episodic volunteering, and to develop a theoretical model of volunteer retention. The findings are intended to provide an evidence base and recommendations for non-profit sector policy and practice.Read 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

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
Do director board appointments predict whether CEO pay is in line with company performance? Increasing pay differences between CEOs and the average working Australian have resulted in a less equitable and economically divided society. This issue has reached a critical point as taxpayer money is now needed to fund stimulus packages and finance companies facing insolvency while CEO pay on average has remained unchanged or increased.

Increasing pay differences between CEOs and the average working Australian have resulted in a less equitable and economically divided society. This issue has reached a critical point as taxpayer money is now needed to fund stimulus packages and finance companies facing insolvency while CEO pay on average has remained unchanged or increased. This inequity has the potential to cause social and political instability. This research will provide much needed knowledge of how to address this issue including pay benchmarks, knowledge derived from international practice, corporate governance indices as well as understanding of how widespread pay norms have developed.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
