Extending Cognitive Models to Account for Individual Differences. Despite their impressive achievements, cognitive models of memory retention, category learning, and stimulus representation usually model people as ?invariants?, concentrating on what makes them the same. This project aims to extend all three types of model to also treat people as ?individuals?, and account for how people are different. Advanced model selection methods will be used to do this in a way that is complete, general, an ....Extending Cognitive Models to Account for Individual Differences. Despite their impressive achievements, cognitive models of memory retention, category learning, and stimulus representation usually model people as ?invariants?, concentrating on what makes them the same. This project aims to extend all three types of model to also treat people as ?individuals?, and account for how people are different. Advanced model selection methods will be used to do this in a way that is complete, general, and principled. The outcome will be a set of new theoretical models, and new algorithms to learn the models from empirical data, that explain the differences between people in remembering, learning and representing information.Read moreRead less
Predicting misdiagnoses in the transition from competence to expertise. This project aims to test whether the utilisation of cues predicts vulnerability to misdiagnosis during skill acquisition. This project uses newly developed measures of cue utilisation, together with innovative, on-line scenarios and a longitudinal design, to measure different types of misdiagnosis amongst qualified radiologists, pathologists and pilots as they acquire expertise. With potential applications in medicine, avia ....Predicting misdiagnoses in the transition from competence to expertise. This project aims to test whether the utilisation of cues predicts vulnerability to misdiagnosis during skill acquisition. This project uses newly developed measures of cue utilisation, together with innovative, on-line scenarios and a longitudinal design, to measure different types of misdiagnosis amongst qualified radiologists, pathologists and pilots as they acquire expertise. With potential applications in medicine, aviation, energy, transportation, and defence, the expected outcomes will facilitate interventions such as targeted training and the provision of technical support, that will guide the diagnostic process and thereby reduce the impact of misdiagnoses on individuals and infrastructure.Read moreRead less
Empathy, Attention and Reasoning: The role of automatic and controlled processing in emotion recognition following traumatic brain injury. Traumatically brain injured adults have difficulty identifying emotional facial expressions but little is known regarding their psychophysiological reactions to emotional expression, the efficacy of their visual search patterns of facial features or the extent to which they engage conscious processing and problem solving to assist interpretation. Nor is anyth ....Empathy, Attention and Reasoning: The role of automatic and controlled processing in emotion recognition following traumatic brain injury. Traumatically brain injured adults have difficulty identifying emotional facial expressions but little is known regarding their psychophysiological reactions to emotional expression, the efficacy of their visual search patterns of facial features or the extent to which they engage conscious processing and problem solving to assist interpretation. Nor is anything known about their ability to recognise dynamic emotional displays compared to photographs. This project examines each of these facets using static and dynamic portrayals. The project will inform neuropsychological theories of facial processing, test the ecological validity of previous research and improve understanding of psychosocial deficits after TBI and their treatment.Read moreRead less
Multidimensional unfolding: the latitude of acceptance and the structure of the single peaked response process in a multidimensional space. The latitude of acceptance and the operational function that structures the single peaked response process have only recently been understood as central to unidimensional models for the measurement of attitude, preference and choice. They have been neglected in multidimensional models. This project will formalise these two central components in a multidimens ....Multidimensional unfolding: the latitude of acceptance and the structure of the single peaked response process in a multidimensional space. The latitude of acceptance and the operational function that structures the single peaked response process have only recently been understood as central to unidimensional models for the measurement of attitude, preference and choice. They have been neglected in multidimensional models. This project will formalise these two central components in a multidimensional space. The operational function governs the relationship between any item-person distance and the latitude of acceptance defines a multidimensional hyper-sphere within which the more positive response is more likely. The project will articulate and operationalise these models for a range of typical response formats from ranking to pairwise preferences.Read moreRead less

Predicting the diagnostic performance of individuals and organisations. This project aims to address diagnostic error in advanced technology systems, by providing a mechanism to assess and improve individual diagnosticians’ performance. Organisations that rely on their employees’ diagnostic skills rarely assess them once the operators become qualified, so there is no basis for interventions that might prevent diagnostic errors affecting thousands. This research tests a new method of assessing diagnostic skills based on how skilled operators respond to cues. This project will test how employees’ diagnostic skills change and whether this change corresponds to measures of organisational performance. This research is expected to provide organisations with a tool to pre-empt diagnostic errors that could minimise costs to the economy.Read moreRead less
An innovative measure of rural health and wellbeing: rapid appraisal via analysis of patterns of calls to Lifeline. Rural Australians are reported to experience poorer health and wellbeing on a wide range of indicators. However, serious problems exist with the validity and reliability of these data. This project will analyse the 85,000 calls to Lifeline made each year by rural Australians. For several reasons, use of telephone counselling services would appear to be a sensitive measure of rural ....An innovative measure of rural health and wellbeing: rapid appraisal via analysis of patterns of calls to Lifeline. Rural Australians are reported to experience poorer health and wellbeing on a wide range of indicators. However, serious problems exist with the validity and reliability of these data. This project will analyse the 85,000 calls to Lifeline made each year by rural Australians. For several reasons, use of telephone counselling services would appear to be a sensitive measure of rural community health. By triangulating primary data (community case studies using the critical incident technique) and secondary data (SEIFA and Jesuit index), this project will develop and test Lifeline calls as an index for rapidly appraising community health and wellbeing.Read moreRead less

Neurobiology of parenting and disruptive behaviour disorders in childhood. This project aims to examine the genetic determinants and contribution of parenting to childhood disruptive behaviour disorders. These disorders are often chronic and associated with comorbid conditions in later life, creating enormous personal and social costs for individuals and families, and a burden on the economy. About a third of children do not respond to current forms of early intervention, so clinicians need evid ....Neurobiology of parenting and disruptive behaviour disorders in childhood. This project aims to examine the genetic determinants and contribution of parenting to childhood disruptive behaviour disorders. These disorders are often chronic and associated with comorbid conditions in later life, creating enormous personal and social costs for individuals and families, and a burden on the economy. About a third of children do not respond to current forms of early intervention, so clinicians need evidence of the interaction between parenting practices and the developmental aspects of these disorders This project will examine oxytocin genetics in toddlers with disruptive behaviour disorders and their parents, to ultimately identify the genetic, family, and developmental processes that shape persistent disorders.Read moreRead less

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
