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
A philosophical and empirical approach to the nature of perception and belief. This project offers substantial benefits - intellectual, practical, and ultimately economic - to the nation.

On the practical side, the project offers the prospect of ....A philosophical and empirical approach to the nature of perception and belief. This project offers substantial benefits - intellectual, practical, and ultimately economic - to the nation. On the intellectual side, the project will contribute to research output and will further enhance the national research strength in the study of delusions, rationality, and agency, within both philosophy of mind and inter-disciplinary cognitive science. On the practical side, the project offers the prospect of considerable benefits for the community as improved theories of the nature and causes of delusions generate strategies for earlier detection or even prevention of the development of delusions, new methods of therapy for patients, and better understanding for families.Read moreRead less

Improving eyewitness identification accuracy using free-report lineups. There is major national and community interest in the successful conduct of criminal investigations. This research addresses the accuracy of eyewitness identification tests. Specifically, we investigate whether developing lineup procedures that separate out witnesses who are unsure of their response will prevent erroneous identifications. Progress on this issue makes an important contribution to decisions about the ideal lin ....Improving eyewitness identification accuracy using free-report lineups. There is major national and community interest in the successful conduct of criminal investigations. This research addresses the accuracy of eyewitness identification tests. Specifically, we investigate whether developing lineup procedures that separate out witnesses who are unsure of their response will prevent erroneous identifications. Progress on this issue makes an important contribution to decisions about the ideal lineup procedure, thereby preventing innocent people from being prosecuted and perpetrators being free to re-offend. Additionally the international collaboration on the project will increase the visibility of Australian social science research and provide crucial development opportunities for young Australian scientists.Read moreRead less
Identifying the bad guy with deadlined confidence judgments. There is major interest in the successful conduct of criminal investigations. Identity tests are commonly used in such investigations, but eyewitness decision accuracy is still unacceptably low. While eyewitness memory research has already contributed significantly to the development of procedures that improve the diagnosticity of identification decisions, our proposal offers radical new alternatives that can significantly improve diag ....Identifying the bad guy with deadlined confidence judgments. There is major interest in the successful conduct of criminal investigations. Identity tests are commonly used in such investigations, but eyewitness decision accuracy is still unacceptably low. While eyewitness memory research has already contributed significantly to the development of procedures that improve the diagnosticity of identification decisions, our proposal offers radical new alternatives that can significantly improve diagnosticity. In refining and evaluating these alternatives we will boost the profile of Australian science research and provide rich international training environments for young Australian and overseas scientists.Read moreRead less
Interviewing eyewitnesses: Enhancing output quantity and diagnosing accuracy. Although there has been general international agreement that open-ended police interviews (e.g., the Cognitive Interview) enhance output quantity and accuracy, it is also well documented that police investigators often depart from these procedures in order to probe for additional information. An approach to eyewitness interviewing that allows police to elicit greater detail while able to assess likely accuracy not only ....Interviewing eyewitnesses: Enhancing output quantity and diagnosing accuracy. Although there has been general international agreement that open-ended police interviews (e.g., the Cognitive Interview) enhance output quantity and accuracy, it is also well documented that police investigators often depart from these procedures in order to probe for additional information. An approach to eyewitness interviewing that allows police to elicit greater detail while able to assess likely accuracy not only has the potential to be widely adopted but would also provide a major breakthrough in the investigation of crimes and other incidents where interview data are so critical. This in turn would further enhance the profile of Australian (and UK) forensic science.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. 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 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
