The human face as an evolved signalling system. This project will, for the first time, thoroughly investigate the role that facial movement plays in human non-verbal communication. It will uncover the subtle, dynamic signals that are exchanged in almost all everyday social encounters, enriching our understanding of human communication and forming a solid basis for detecting intentions from an analysis of facial movements, with the obvious security benefits that entails.

This unique study of sophisticated behavioural flexibility and dynamic sensory exploitation in an insect will provide novel insights into how simple cognitive architecture can be used to solve complex problems. These insights are important for the development of artificial intelligence systems. This will be the first study of flexible aggressive mimicry in an insect and will attract considerable international attention, raise the profile of Australian science and support numerous students. We will make the first use in Australia of state-of-the-art vibration recording and interactive playback techniques. Making these powerful experimental tools available in Australia will enable other many additional innovative lines of research.Read moreRead less
Electrophysiological correlates of verbal and visuospatial working memory. Successful interaction with the world is dependent on "working memory". This memory system holds things in mind, while relating them to the past and planning for the future. A carefully controlled task, presented on a computer screen, systematically increases the number of items to be kept in mind. Accuracy and speed of matching the items are measured. The results will contribute to a theory of what processes are used ....Electrophysiological correlates of verbal and visuospatial working memory.

'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. This project takes an innovative approach to the experimental analysis of human reasoning and de ....'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. 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
Integrating Models of Memory for Serial Order. This research aims to compare and integrate computational models of memory for serial order. The applicants have independently developed theoretically novel models, and this collaboration will enable them to combine and strengthen their complementary perspectives.
Much psychologically important processing, for example speech perception and spelling, requires the representation and reproduction of serial order information. Existing models account ....Integrating Models of Memory for Serial Order. This research aims to compare and integrate computational models of memory for serial order. The applicants have independently developed theoretically novel models, and this collaboration will enable them to combine and strengthen their complementary perspectives.
Much psychologically important processing, for example speech perception and spelling, requires the representation and reproduction of serial order information. Existing models account for a wide range of data and collectively represent exciting progress in the understanding of basic mechanisms of memory. Can these models be unified and reconciled? To date, detailed comparisons of models are lacking. This proposal is for the applicants to elaborate and unify their contrasting theoretical approaches.

Music cognition in infants, children and adults. Music is an important tool for the expression of emotion and transmission of culture. One approach to understanding why music is a human universal is to examine how people process musical structure - the simultaneous and sequential pitch relations among tones of musical pieces. We investigate the way humans acquire implicit and explicit knowledge of such relations and the way exposure to music influences acquisition. Three experiments involving in ....Music cognition in infants, children and adults. Music is an important tool for the expression of emotion and transmission of culture. One approach to understanding why music is a human universal is to examine how people process musical structure - the simultaneous and sequential pitch relations among tones of musical pieces. We investigate the way humans acquire implicit and explicit knowledge of such relations and the way exposure to music influences acquisition. Three experiments involving infants, children and adults will compare formal musical training with incidental learning. Results will increase knowledge of the development of auditory perception and music cognition. Infant perceptual predispositions hold implications for music education.Read moreRead less
Associability processes in propositional learning. A novel attentional model of learning is evaluated in this project. In this model, learning is seen not as a consequence of a low-level, evolutionarily old system shared with our ancestors, but as a product of our capacity to apply rules and engage in reasoning. Understanding the role of attention in learning will allow a better understanding of the attentional biases seen in clinical disorders such as addiction and a new way to think about the ....Associability processes in propositional learning.

Understanding the role of attention in learning will allow a better understanding of the attentional biases seen in clinical disorders such as addiction and a new way to think about the neuroscience of attention. These benefits may further suggest new lines of research in the development of drugs to combat attentional disorders.Read moreRead less
A new theory of visual word recognition and reading aloud. The results of this research will lead to an improvement in the theory of reading, which will in turn improve the quality of advice to speech pathologists, teachers, parents and the broader community about children’s reading difficulties and their treatment.
The role of time and similarity in short-term memory. The project examines the role of time and similarity in memory for serial order, with the long-term goal to construct a new computational model of short-term memory. The investigators are internationally known for their models, and the collaboration will enable them to combine their complementary perspectives into a unifying theory. Theory construction will be guided by two sets of studies: The first will delineate the circumstances, if any, ....The role of time and similarity in short-term memory. The project examines the role of time and similarity in memory for serial order, with the long-term goal to construct a new computational model of short-term memory. The investigators are internationally known for their models, and the collaboration will enable them to combine their complementary perspectives into a unifying theory. Theory construction will be guided by two sets of studies: The first will delineate the circumstances, if any, under which temporal separation at encoding affects memory. So far, we have shown that temporal distinctiveness has no effect on memory, unless people use temporal gaps to 'chunk' the list. The second set of studies will examine whether phonological similarity determines the strength of encoding.Read moreRead less
The Control of Memory Access. The topic of control processes in memory access is central to most of the big questions about human memory such as; why we forget, what produces spectacular and tragic memory failures (e.g.,lighting a match to check the level of petrol in a tank) and the role of context in familiarity and recollection. Because of the centrality of the problems addressed there will be many applications for the results. The long term results will include better models for human ope ....The Control of Memory Access. The topic of control processes in memory access is central to most of the big questions about human memory such as; why we forget, what produces spectacular and tragic memory failures (e.g.,lighting a match to check the level of petrol in a tank) and the role of context in familiarity and recollection. Because of the centrality of the problems addressed there will be many applications for the results. The long term results will include better models for human operators which can be used in both civilian (e.g., air traffic control) and military applications. Other areas of application will include how we measure memory impairment, why we make errors in industrial settings, and the nature of memory deficits as we age. Read moreRead less
