For the first time scientists are beginning to reveal the complex relationship between human brain function and behaviour. These advances have stemmed almost exclusively from the development of sophisticated brain scanning techniques that provide high-resolution images of physiological changes associated with perceptual, cognitive and motor behaviours. This application seeks support for a state-of-the-art scanner to obtain high-resolution images of the brain as healthy adults perceive, think, learn, remember and decide. The facility will enable Australian scientists to understand the complex links between brain and behaviour in health and disease.Read moreRead less

Summary
The Creation of an Eye Movement Recording Facility in Queensland. There are countless uses for technology that records visual behaviour; these include reading and cognitive psychology research, ergonomic design, web site usability testing, and evaluation of visual information (for example advertising or in ?virtual? environments). As such, recording eye movements has applications in pure and applied research, and in teaching demonstrations for students.

There are countless uses for technology that records visual behaviour; these include reading and cognitive psychology research, ergonomic design, web site usability testing, and evaluation of visual information (for example advertising or in ?virtual? environments). As such, recording eye movements has applications in pure and applied research, and in teaching demonstrations for students.
This application proposes to purchase eye movement recording equipment to form a dedicated and truly collaborative facility to measure visual behaviour. The facility would be unique in Australia and would be invaluable to both further understand visual/cognitive processes and how individuals interact with their environments.Read moreRead less
Biased information processing in anxiety: Low anxiety scores, but still at risk. Information processing in anxious persons is biased if confronted with threatening stimulus materials such as words or pictures. This finding has considerable implications for our understanding of fear acquisition and maintenance and for the design of therapeutic interventions. More recent research has shown, however, that low anxious persons who employ repressive coping styles show similar biases. The present proj ....Biased information processing in anxiety: Low anxiety scores, but still at risk. Information processing in anxious persons is biased if confronted with threatening stimulus materials such as words or pictures. This finding has considerable implications for our understanding of fear acquisition and maintenance and for the design of therapeutic interventions. More recent research has shown, however, that low anxious persons who employ repressive coping styles show similar biases. The present project will follow up on these findings by combining the expertises of the two CIs in contemporary cognitive and psychophysiological research. It will not only provide new insights, but also offer research opportunities for postgraduate students, and prospects for future collaborative funding.Read moreRead less
The many faces of threat: An investigation of animal, interpersonal and intergroup threat. Threat to personal safety can take a number of guises, a snake in the grass, an angry neighbour or, increasingly often in our modern world, a stranger who looks different. The present project will investigate the manner in which we respond to these threats, whether these responses can be modulated and what determines the threatening nature of an event. A better understanding of how we react to real or p ....The many faces of threat: An investigation of animal, interpersonal and intergroup threat. Threat to personal safety can take a number of guises, a snake in the grass, an angry neighbour or, increasingly often in our modern world, a stranger who looks different. The present project will investigate the manner in which we respond to these threats, whether these responses can be modulated and what determines the threatening nature of an event. A better understanding of how we react to real or perceived threats, in particular those involving other humans, will aid our understanding of human behaviour in an ever faster changing environment, both in our region and more broadly.

How does dopamine modulate adult new word learning? Stroke is a chronic disease of increasing prevalence with increasing age. There is a critical need to develop more effective treatments of communication disorders in this population. One way of achieving this is to combine certain drugs with language therapy.

Stroke is a chronic disease of increasing prevalence with increasing age. There is a critical need to develop more effective treatments of communication disorders in this population. One way of achieving this is to combine certain drugs with language therapy. Through studying how these drugs influence language, this research will provide vital knowledge for developing effective forms of pharmacotherapy for adults with language disorders after brain injury. More effective language rehabilitation can have direct positive consequences on the ability to regain and maintain employment and social relationships after stroke or brain injury and will address the large and growing social and economic cost to the nation.Read moreRead less
Human learning of likes and dislikes: A test of the dual process account and an investigation of its neural substrates. Dual process accounts of human affective learning hold that affective learning, the learning of likes and dislikes, and relational learning, the learning of predictive relationships, reflect separate learning mechanisms. Affective learning, for instance, is said not to extinguish, a claim that has far reaching consequences for the design of behaviourally based treatments of a ....Human learning of likes and dislikes: A test of the dual process account and an investigation of its neural substrates. Dual process accounts of human affective learning hold that affective learning, the learning of likes and dislikes, and relational learning, the learning of predictive relationships, reflect separate learning mechanisms. Affective learning, for instance, is said not to extinguish, a claim that has far reaching consequences for the design of behaviourally based treatments of anxiety. The project will test this and other predictions of dual process accounts. Moreover, it will extent the experimental analysis of affective learning to the acquisition of likes and identify the cortical bases for aversive, appetitive, and relational learning using event related functional magnetic resonance imaging.Read moreRead less
How, What and Who in Human Communication: Movement of Face and Voice. The aim of this project is to identify the essential characteristics of tone, affect, and identity from face and voice using a combination of signal processing, biological, and behavioural techniques in order to develop a comprehensive model of auditory-visual speech processing and communication. This research will significantly improve understanding of the basis of auditory-visual perception and production in tonal languages ....How, What and Who in Human Communication: Movement of Face and Voice. The aim of this project is to identify the essential characteristics of tone, affect, and identity from face and voice using a combination of signal processing, biological, and behavioural techniques in order to develop a comprehensive model of auditory-visual speech processing and communication. This research will significantly improve understanding of the basis of auditory-visual perception and production in tonal languages and in affective communication, facilitate links between neurophysiological processes and auditory-visual speech processing; and contribute to applications in automatic person recognition, automatic speech recognition, text-to-speech systems, and talking head aids for the hearing impaired.Read moreRead less
A functional imaging study of semantic processing modulated by dopamine. The role of dopamine in language processing is largely unknown, despite emerging evidence that dopaminergic alterations can modulate language in schizophrenia, Parkinson's disease, and healthy individuals. The research aims to reveal the neural and behavioural correlates of dopaminergic modulation of semantic processing using neuroimaging in healthy individuals who have ingested levodopa. It is hypothesised that levodopa wi ....A functional imaging study of semantic processing modulated by dopamine. The role of dopamine in language processing is largely unknown, despite emerging evidence that dopaminergic alterations can modulate language in schizophrenia, Parkinson's disease, and healthy individuals. The research aims to reveal the neural and behavioural correlates of dopaminergic modulation of semantic processing using neuroimaging in healthy individuals who have ingested levodopa. It is hypothesised that levodopa will modulate brain activity under circumstances where there is heightened semantic competition, consistent with a contemporary theory of dopaminergic cognitive control. The expected outcome of the research is an increased understanding of the interactions between dopamine, the language faculty, and associated neural systems.Read moreRead less
'As-if thinking': an experimental analysis of human reasoning and decision-making. The failure to respond adequately to the havoc wreaked by Hurricane Katrina in 2005 highlighted the difficulty of sequential decision-making. Responses to such emergencies require detailed contingency plans, necessitating a consideration of all possible outcomes of a situation regardless of their objective probability.

The failure to respond adequately to the havoc wreaked by Hurricane Katrina in 2005 highlighted the difficulty of sequential decision-making. Responses to such emergencies require detailed contingency plans, necessitating a consideration of all possible outcomes of a situation regardless of their objective probability. This project takes an innovative approach to the experimental analysis of human reasoning and decision-making, with the aim of identifying the mechanisms, factors, and boundary conditions affecting inferences and decisions about uncertain alternatives. The research will inform planning for Australia's readiness to respond to unpredictable events with uncertain outcomes and enhance the reputation of Australian science.Read moreRead less
Smells that 'taste': Flavour perception and its consequences. The experience of flavour during eating and drinking has surprising social and economic ramifications. Our preference for sweet and fatty food has contributed to progressive increases in body mass over the last twenty years.

The experience of flavour during eating and drinking has surprising social and economic ramifications. Our preference for sweet and fatty food has contributed to progressive increases in body mass over the last twenty years. Many experts now consider this to be a major public health crisis in the making. Economically, Australia is heavily dependent upon food exports, both in terms of primary production and value added processed food. Understanding the psychology of flavour, which is central to this project, should assist the development of non-fattening additives that appreciably alter fat and sweetness perception, creating new food products that are healthy, preferred and potential export earners.
