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.

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

MOVEMENT & COMMUNICATION ANALYSIS LAB & PORTABLE AUDIENCE RESPONSE FACILITY. The equipment establishes an integrated movement analysis laboratory and audience response facility to support and extend ongoing collaborative research projects that investigate human visual and auditory communication through gestures of voice and body. This laboratory will allow recording and analysis of fine and gross motor activity in: caregiver-infant and therapist-client interaction; auditory-visual speech percept ....MOVEMENT & COMMUNICATION ANALYSIS LAB & PORTABLE AUDIENCE RESPONSE FACILITY. The equipment establishes an integrated movement analysis laboratory and audience response facility to support and extend ongoing collaborative research projects that investigate human visual and auditory communication through gestures of voice and body. This laboratory will allow recording and analysis of fine and gross motor activity in: caregiver-infant and therapist-client interaction; auditory-visual speech perception; audience reactions to gesture and dance. The audience response facility, a portable system of small keypads programmed to record discrete and continuous responses, brings precision to recording psychological responses in a naturalistic setting. The combined equipment allows concerted investigation of human communicative gesture.Read moreRead less
Can the Relational Account predict search in multiple-element displays? . This project provides evidence of a novel mechanism that guides visual attention. Our results confirm the existence of a mechanism that can rapidly and automatically assess the dominant feature(s) in a visual scene and radically change how attention is tuned to a target object. Moreover, this attention-guiding target template can change systematically as observers search through different items in visual search, possibly d ....Can the Relational Account predict search in multiple-element displays? . This project provides evidence of a novel mechanism that guides visual attention. Our results confirm the existence of a mechanism that can rapidly and automatically assess the dominant feature(s) in a visual scene and radically change how attention is tuned to a target object. Moreover, this attention-guiding target template can change systematically as observers search through different items in visual search, possibly due to a re-shaping and narrowing of the target template. These are both ground-breaking discoveries that have not been described before. Work on this project promises to lead to important theoretical breakthroughs, resolve current discrepancies in the literature and advance methods of Cognitive Psychology and Neuroscience.Read moreRead less
Establishing how head and face movement properties contribute to the perception of speech and identity. The proposed studies provide an extensive research program into audio-visual speech processing and person identification: key components of face-to-face communication.

The proposed studies provide an extensive research program into audio-visual speech processing and person identification: key components of face-to-face communication. The likely impact and benefits of the project concern its contribution to perceptual theory (linking signal, brain and behaviour) and its practical implications: For determining the viability of multimodal biometric identification procedures by assessing the distinctiveness and permanence of AV speech characteristics. In the development of a visual dubbing technique that has potential for communication in noisy environments (and for the deaf) and for the development of a morphable model for AV presentation that has application for both first and second language learning.Read moreRead less

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
