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
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.

Hazard Perception and Cognitive Ageing in Older Drivers: Investigation and Development. Older road users have high fatal crash rates that cost the Australian economy $500 million each year. However, driving cessation is associated with depression and reduced social participation among older adults. The present study will benefit older road users and the wider community by identifying which traffic hazards pose the greatest difficulty for older drivers and providing information that may lead to a ....Hazard Perception and Cognitive Ageing in Older Drivers: Investigation and Development. Older road users have high fatal crash rates that cost the Australian economy $500 million each year. However, driving cessation is associated with depression and reduced social participation among older adults. The present study will benefit older road users and the wider community by identifying which traffic hazards pose the greatest difficulty for older drivers and providing information that may lead to adaptation of roads, and vehicles to reduce crash risk among older Australians. This will reduce injury and healthcare costs and allow older Australians to maintain higher levels of social participation.Read moreRead less
The roles of spectral cues and auditory plasticity in auditory localisation, speech segregation and speech intelligibility. Our recent work shows that high frequency energy in speech is important for the localisation of speech and may also aid in improving speech intelligibility in noisy environments.

Our recent work shows that high frequency energy in speech is important for the localisation of speech and may also aid in improving speech intelligibility in noisy environments. The work proposed here will systematically explore this somewhat surprising new finding and the results will be incorporated into a predictive model of speech intelligibility under spatial listening conditions. This work includes a systematic study of auditory functional plasticity to changes in the spatial cues. Taken together, the outcomes of this work will unlock a range of new approaches to enhancing spatial hearing in multi-channel communication devices and spatial hearing aids.Read moreRead less
Acoustic, spatial and informational cues used to solve the cocktail party problem. Speech is the principal mode of human communication and yet we understand little about how we are able to concentrate on one talker against a noisy background. Significant improvements in supporting listening by the hearing impaired, in teleconferencing systems and computer speech interfaces are dependent on a more advanced understanding of how we solve this cocktail party problem. This research explores the acous ....Acoustic, spatial and informational cues used to solve the cocktail party problem. Speech is the principal mode of human communication and yet we understand little about how we are able to concentrate on one talker against a noisy background. Significant improvements in supporting listening by the hearing impaired, in teleconferencing systems and computer speech interfaces are dependent on a more advanced understanding of how we solve this cocktail party problem. This research explores the acoustic, spatial and informational cues used by the healthy auditory system to achieve this remarkable feat of signal processing. There is significant potential for commercialization of the IP that will arise from this research.Read moreRead less

Identification and Examination of Visual Cues for Aircraft Glideslope Control. While aviation safety has improved dramatically over the last 50 years, accidents are still more common during landing than any other stage of flight. This project aims to improve our understanding of the way pilots use visual information to land an aircraft. Once our findings have been incorporated into existing training programs, this much-needed information should result in: (i) reduced pilot training time and cost ....Identification and Examination of Visual Cues for Aircraft Glideslope Control. While aviation safety has improved dramatically over the last 50 years, accidents are still more common during landing than any other stage of flight. This project aims to improve our understanding of the way pilots use visual information to land an aircraft. Once our findings have been incorporated into existing training programs, this much-needed information should result in: (i) reduced pilot training time and cost; (ii) increased trainee pilot safety and confidence; and (iii) reduced aircraft maintenance costs. A PhD student, who will be trained in visual perception and aviation, should contribute significantly to future aviation research in this country.Read moreRead less

This project is based on an innovative account linking such disappearances to a functional adaptation which facilitates vision in cluttered environments. Project completion will expand Australia's knowledge base, forge links between junior and senior Australian based investigators and provide excellent training opportunities. Publication of research in top-ranking international journals will further promote Australian science abroad. Ultimately, this research will have implications for the design and implementation of artificial visual systems, which must overcome many of the same dilemmas faced by the human visual system in cluttered environments.Read moreRead less
Human time perception: A crossmodal investigation. This research program investigates time perception in humans in the subsecond range. Time perception is a crucial aspect of cognitive functioning but one that is poorly understood. The subsecond scale is particularly relevant because it is the time-frame for crucial tasks such as motor coordination, speech perception and crossmodal integration. This project examines time in an audiovisual context, exploring the cognitive limits of our ability to ....Human time perception: A crossmodal investigation. This research program investigates time perception in humans in the subsecond range. Time perception is a crucial aspect of cognitive functioning but one that is poorly understood. The subsecond scale is particularly relevant because it is the time-frame for crucial tasks such as motor coordination, speech perception and crossmodal integration. This project examines time in an audiovisual context, exploring the cognitive limits of our ability to keep track of time and testing whether time is encoded as a basic feature. These experiments will further our knowledge of time perception and lead to improved models of how the brain encodes time.Read moreRead less
