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
Who may judge a book by its cover? This project aims to build a model of how and why people vary in their impressions of others and in the accuracy of these impressions. People readily form impressions of others from their faces and these impressions influence crucial decisions: election results, court case outcomes and partner choices. To build this model, the project will apply twin data and construct a psychometric test to measure variation in facial impressions. The research is expected to l ....Who may judge a book by its cover? This project aims to build a model of how and why people vary in their impressions of others and in the accuracy of these impressions. People readily form impressions of others from their faces and these impressions influence crucial decisions: election results, court case outcomes and partner choices. To build this model, the project will apply twin data and construct a psychometric test to measure variation in facial impressions. The research is expected to lead to insights into this aspect of social perception, and to identify the sources of atypical or inaccurate facial judgements. This has applications in health contexts (to identify social impairment) and in security contexts (for personnel selection).Read moreRead less
Filters reveal what flicker conceals: temporal processing in the human visual system. I have recently discovered a new form of camouflage using 10Hz luminance flicker. This project will quantify this effect and examine the extent to which it generalises across colour and spatial dimensions and to video sequences depicting natural scenes. This information is expected to provide foundational information to technologies relating to national security that rely on visual concealment. This research wi ....Filters reveal what flicker conceals: temporal processing in the human visual system. I have recently discovered a new form of camouflage using 10Hz luminance flicker. This project will quantify this effect and examine the extent to which it generalises across colour and spatial dimensions and to video sequences depicting natural scenes. This information is expected to provide foundational information to technologies relating to national security that rely on visual concealment. This research will examine the extent to which filtering out these camouflaging frequencies enhances our sensitivity to low temporal frequency information. This decamouflaging aspect of my research is expected to improve the clarity of digital video-based technologies including ultrasound, educational, info-tainment and defence applicationsRead 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 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 identificati ....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 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
Pathways to work engagement, wellbeing and positive teaching among mid-career teachers: The role of personal and workplace resources. Teaching is a highly demanding, yet rewarding career for many. It is also a decidedly stressful occupation associated with high burnout. By following a large sample of teachers recruited ten years earlier into their mid-career, this project investigates the coping and motivational resources that keep them engaged, allowing them to thrive personally and professiona ....Pathways to work engagement, wellbeing and positive teaching among mid-career teachers: The role of personal and workplace resources. Teaching is a highly demanding, yet rewarding career for many. It is also a decidedly stressful occupation associated with high burnout. By following a large sample of teachers recruited ten years earlier into their mid-career, this project investigates the coping and motivational resources that keep them engaged, allowing them to thrive personally and professionally in different kinds of school environments, versus pathways that predict to burnout, ill-being and negative teaching behaviours. Selected subgroups who were most at risk and most positively engaged earlier in their career will be the focus of longitudinal case studies to uncover more nuanced processes promoting positive and negative pathways.Read moreRead less
Peer Rejection and the Maladaptive Social Behaviour of Children and Adolescents. Research indicates that peer rejection has serious negative effects on child and adolescent victims. However, little research has addressed the likelihood that peer rejection also has negative consequences for others in the social environment, through its instigation of maladaptive social behaviours such as bullying and ethnic prejudice. Given the incidence of the latter behaviours in primary and secondary schools, ....Peer Rejection and the Maladaptive Social Behaviour of Children and Adolescents. Research indicates that peer rejection has serious negative effects on child and adolescent victims. However, little research has addressed the likelihood that peer rejection also has negative consequences for others in the social environment, through its instigation of maladaptive social behaviours such as bullying and ethnic prejudice. Given the incidence of the latter behaviours in primary and secondary schools, the aim of this project is to conduct a program of research to test an integrative model of the impact of peer rejection on the maladaptive social behaviours of children and adolescents, with a particular focus on ethnic prejudice and bullying.Read moreRead less
Children's Intergroup Prejudice: The Roles of Cognitive Representations and Self-presentation. Research indicates that intergroup prejudice remains a problem in most Australian schools. For example, children as young as 5-6 years assign negative attributes to indigenous Australians and Pacific Islander children, they prefer not to play with these children, and they do not even want them living nearby. The proposed research will examine the possible basis of age effects in these attitudes. It wi ....Children's Intergroup Prejudice: The Roles of Cognitive Representations and Self-presentation. Research indicates that intergroup prejudice remains a problem in most Australian schools. For example, children as young as 5-6 years assign negative attributes to indigenous Australians and Pacific Islander children, they prefer not to play with these children, and they do not even want them living nearby. The proposed research will examine the possible basis of age effects in these attitudes. It will have a substantial national benefit because it will increase our understanding of this insidious social phenomenon and provide a basis for developing an intervention that will minimise a problem that has the potential to devastate community relations.

From Anxious Temperament to Disorder: The role of the parent- child interaction. Three studies are proposed. The first examines parent behaviour (overinvolvement, encouragement of avoidance) in a large group of inhibited and uninhibited preschoolers over two-years. The aim is to determine whether parent behaviour places an inhibited child at greater risk of developing an anxiety disorder. The second examines parents of anxious children interacting with non-clinical children and parents of non-cl ....From Anxious Temperament to Disorder: The role of the parent- child interaction. Three studies are proposed. The first examines parent behaviour (overinvolvement, encouragement of avoidance) in a large group of inhibited and uninhibited preschoolers over two-years. The aim is to determine whether parent behaviour places an inhibited child at greater risk of developing an anxiety disorder. The second examines parents of anxious children interacting with non-clinical children and parents of non-clinical children interacting with anxious children. It is expected that anxious children will elicit more help from non-clinical mothers. The third examines anxiety-disordered parents interacting with their children. It is expected that anxiety-disordered mothers would be overinvolved regardless of the child's anxiety.Read moreRead less

This project will enhance our understanding of the influence of children's social groups on school bullying and victimization. Increasing understanding of this devastating social phenomenon will provide a basis for developing focused intervention strategies that are directed at both bullies and victims. In turn, this will improve the learning context for all students, enhance the environment in which teachers work, and strengthen the fabric of communities by contributing to the development of harmony and cooperation between people.Read moreRead less
Making Australia internationally competitive: driving educational attainment by academic motivation, self-concept, engagement and aspirations. This project will extend and test predictions from motivation theory about educational choice and attainment, using multiple large national/international databases and new statistical models. This will result in better strategies to meet government targets of increasing tertiary enrolments, particularly for disadvantaged students.
