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.

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
Managing compliance with procedural justice: The role of motivational postures, legitimacy and emotion. Regulatory authorities exist to ensure that members of the public comply with their obligations under the law. At the same time, however, regulators should not exercise their authority in ways that result in the alienation of the public. Using social science methodology, this project will examine the role that procedurally fair regulation can play in promoting trust and confidence in authoriti ....Managing compliance with procedural justice: The role of motivational postures, legitimacy and emotion. Regulatory authorities exist to ensure that members of the public comply with their obligations under the law. At the same time, however, regulators should not exercise their authority in ways that result in the alienation of the public. Using social science methodology, this project will examine the role that procedurally fair regulation can play in promoting trust and confidence in authorities. The national and community benefits of this project will include ascertaining how greater levels of cooperation and compliance with regulatory decisions and laws can be facilitated; particularly among those who may feel disgruntled with their experiences with authority.Read moreRead less
Eyewitness identification: Metacognitive influences on choosing behaviour. There is major national and community interest in the successful conduct of criminal investigations. This research addresses the two most significant problems associated with the conduct of eyewitness identification tests: mistaken identifications of innocent suspects and failure to identify guilty suspects when they are present in the lineup. Progress on the latter problem - which results in offenders avoiding detection ....Eyewitness identification: Metacognitive influences on choosing behaviour. There is major national and community interest in the successful conduct of criminal investigations. This research addresses the two most significant problems associated with the conduct of eyewitness identification tests: mistaken identifications of innocent suspects and failure to identify guilty suspects when they are present in the lineup. Progress on the latter problem - which results in offenders avoiding detection - would be a major contribution with national impact. As well as the obvious implications for the conduct of lineups, 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

Who should join the suspect in a police photo array? The traditional police line-up often produces inaccurate decisions, with witnesses failing to pick the culprit or picking an innocent suspect. Surprisingly, despite all the scientific advances with respect to the collection of eyewitness evidence, there is absolutely no objective basis for selecting the ‘fillers’ to accompany the suspect in the line-up. Guidelines merely suggest the fillers should not be too similar or too dissimilar to the su ....Who should join the suspect in a police photo array? The traditional police line-up often produces inaccurate decisions, with witnesses failing to pick the culprit or picking an innocent suspect. Surprisingly, despite all the scientific advances with respect to the collection of eyewitness evidence, there is absolutely no objective basis for selecting the ‘fillers’ to accompany the suspect in the line-up. Guidelines merely suggest the fillers should not be too similar or too dissimilar to the suspect. However, the fillers are likely to have a crucial influence on decision accuracy. This project aims to remedy this striking deficiency by developing and testing a flexible and universally applicable methodology for photo array composition that will optimise judgmental discriminability and curtail bias.Read moreRead less
Checking the validity of photographic identification documents: Enhancing the performance of security personnel through increased understanding of unfamiliar face processing. The ability to accurately establish the identity of an individual is central to the national security of Australia. Identity checking often relies on facial photographs contained on passports and other documents.

The ability to accurately establish the identity of an individual is central to the national security of Australia. Identity checking often relies on facial photographs contained on passports and other documents. Despite the introduction of automated systems, the decision whether a photograph is of a person rests with human operators. Research by CI has demonstrated that this task is difficult and error prone. The proposed research seeks to improve performance by developing a fuller understanding of the nature of the task and the limits of the operators' abilities and by testing possible training and selection procedures.Read moreRead less
Improving human perception of low resolution face images. Low-resolution face images occur in several settings that require a human observer to identify the face or its expression. For example, a crime eyewitness may have seen the perpetrator's face blurred by distance. This project aims to improve low-resolution face perception. Previous approaches have attempted only to improve general image visibility. Here, the novel theoretical idea is to alter the face's structure, tapping knowledge about ....Improving human perception of low resolution face images. Low-resolution face images occur in several settings that require a human observer to identify the face or its expression. For example, a crime eyewitness may have seen the perpetrator's face blurred by distance. This project aims to improve low-resolution face perception. Previous approaches have attempted only to improve general image visibility. Here, the novel theoretical idea is to alter the face's structure, tapping knowledge about higher-level face coding. Manipulations are caricaturing and whole-then-part alternation, as derived from face-space and holistic processing theories, respectively. Effects of viewpoint and own-versus-other race faces are expected to test practical generalisability of the new methods, and thus refine theory.Read moreRead less
A formal signal detection model of eyewitness identification. The project aims to aid in producing better procedures for the collection and assessment of eyewitness identification evidence. In a police line-up, a witness is asked to identify a perpetrator from a group of similar individuals.

The project aims to aid in producing better procedures for the collection and assessment of eyewitness identification evidence. In a police line-up, a witness is asked to identify a perpetrator from a group of similar individuals. Applied research has focused on conditions that optimise witness performance but many of the conclusions from this research have been challenged on the basis that they use inappropriate measures of performance. Recent work has highlighted the usefulness of analyses based on the theory of signal detection. However, the line-up task does not fit easily within standard signal detection paradigms as it combines two tasks; detection and identification. The project aims to understand how these components work in order to measure witness performance.Read moreRead less
Face-space: linking three-dimensional shape and human perception across changing viewing conditions. People, and increasingly machines, use faces to identify and interact with people. One source of information available for this is the three-dimensional (3D) shape of the face. This information, unlike a photograph, does not change with lighting and viewpoint. This project will link measurements of face shape to the perceived similarities and differences between faces we use to make decisions. ....Face-space: linking three-dimensional shape and human perception across changing viewing conditions. People, and increasingly machines, use faces to identify and interact with people. One source of information available for this is the three-dimensional (3D) shape of the face. This information, unlike a photograph, does not change with lighting and viewpoint. This project will link measurements of face shape to the perceived similarities and differences between faces we use to make decisions. This will facilitate the use of 3D databases in diverse applications including establishing identity, making facial reconstructions of victims of crime or disaster, making databases searchable, computer animation, archaeology, and plastic surgery. In particular the work will make physical databases relevant to human perception. Read moreRead less
