Adaptive processes in normal and disordered face perception. Faces provide a wealth of social cues that guide interpersonal interactions, and most individuals are able to distinguish thousands of faces despite their perceptual similarity. This research investigates the foundations of these impressive face-perception skills and how they are disrupted in autism, a developmental disorder in which face perception is impaired. We focus on how the brain adaptively tailors its perceptual apparatus to ....Adaptive processes in normal and disordered face perception. Faces provide a wealth of social cues that guide interpersonal interactions, and most individuals are able to distinguish thousands of faces despite their perceptual similarity. This research investigates the foundations of these impressive face-perception skills and how they are disrupted in autism, a developmental disorder in which face perception is impaired. We focus on how the brain adaptively tailors its perceptual apparatus to interpret the structure of a face, for its identity, emotional content, and even intent. Uncovering how these processes function in normal and abnormal face perception could help develop effective interventions when these processes are disrupted in autism.Read moreRead less
Atypical cognition in autism: preference for nonverbal coding and impaired connectivity? This project will investigate whether individuals with autism prefer to think 'in pictures' rather than use words, and whether their thinking shows evidence of limited connections across brain regions. Establishing either characteristic for autism would provide important direction in improving diagnosis and intervention for affected children.
The cognitive basis of resilience. This project aims to test whether resilience to bad events can be influenced by modifying information processing factors. High resilience reflects the ability to sustain adaptive psychological functioning in the wake of bad events, and affects physical, emotional, social, and economic wellbeing. The project will test the hypothesis that biases in attention and implicational inferencing at differing stages of event processing affect wellbeing. It will use cognit ....The cognitive basis of resilience. This project aims to test whether resilience to bad events can be influenced by modifying information processing factors. High resilience reflects the ability to sustain adaptive psychological functioning in the wake of bad events, and affects physical, emotional, social, and economic wellbeing. The project will test the hypothesis that biases in attention and implicational inferencing at differing stages of event processing affect wellbeing. It will use cognitive methodologies that sensitively assess and manipulate biases, thereby revealing their causal role in the determination of resilience. The findings are expected to directly contribute to national efforts to build healthy and resilient communities.Read moreRead less
Attentional bias, attentional control, and anxiety vulnerability: A test of alternative hypotheses concerning their functional relationship. Elevated anxiety vulnerability (AV) is characterised by two attentional anomalies; an attentional bias to threat (ABT), and impaired attentional control (IAC). These have been the foci of separate lines of investigation. The proposed research will synthesise these disparate lines of inquiry, to significantly progress both in important ways. Innovative parad ....Attentional bias, attentional control, and anxiety vulnerability: A test of alternative hypotheses concerning their functional relationship. Elevated anxiety vulnerability (AV) is characterised by two attentional anomalies; an attentional bias to threat (ABT), and impaired attentional control (IAC). These have been the foci of separate lines of investigation. The proposed research will synthesise these disparate lines of inquiry, to significantly progress both in important ways. Innovative paradigms will be developed to determine the functional relationship between ABT and IAC, and illuminate the nature of their associations with AV. In addition to advancing theoretical understanding of the attentional underpinnings of AV, this research will evaluate the capacity of new cognitive technologies to ameliorate anxiety vulnerability through modification of its attentional substrate.

Cognitive mechanisms underlying readiness to acquire elevated anxious temperament. This research project seeks to identify the cognitive mechanisms that are causally implicated in individual differences in the tendency to elevate anxious temperament in response to stressful environments. It will also seek to establish the extent to which these cognitive mechanisms represent the phenotypic expression of genes associated with greater susceptibility to elevate anxious temperament. Research outcomes ....Cognitive mechanisms underlying readiness to acquire elevated anxious temperament. This research project seeks to identify the cognitive mechanisms that are causally implicated in individual differences in the tendency to elevate anxious temperament in response to stressful environments. It will also seek to establish the extent to which these cognitive mechanisms represent the phenotypic expression of genes associated with greater susceptibility to elevate anxious temperament. Research outcomes will serve to inform the question as to why the same types of environmental stressors can serve to produce vastly different effects on emotional vulnerability for different individuals. The procedures developed during this research will also have the potential to reduce the negative emotional consequences of sustained stress.Read moreRead less
Attentional and interpretive bias in anxiety: Concurrent expressions of a common selective mechanism, or independent mediators of anxiety vulnerability? The proposed research aims to determine whether two key cognitive biases recently shown to causally influence anxiety vulnerability, one involving selective attention to threat and the other involving the selective imposition of threatening interpretations on ambiguity, arise as concurrent manifestations of a common underlying causal mechanism, ....Attentional and interpretive bias in anxiety: Concurrent expressions of a common selective mechanism, or independent mediators of anxiety vulnerability? The proposed research aims to determine whether two key cognitive biases recently shown to causally influence anxiety vulnerability, one involving selective attention to threat and the other involving the selective imposition of threatening interpretations on ambiguity, arise as concurrent manifestations of a common underlying causal mechanism, or instead represent alternative causal pathways in the mediation of this emotional disposition. Resolution of this issue will significantly advance our theoretical understanding of the mechanisms that govern anxiety vulnerability, while also contributing directly to the development of new cognitive technologies designed to therapeutically modify such vulnerability.Read moreRead less
The extinction of human fear. Excessive fear negatively impacts the lives of many Australians - so how can we increase the effectiveness of exposure based treatments to reduce human fear? The present basic research will investigate the process thought to underlie exposure-based treatments, extinction of human fear learning, in order to answer this applied question.
Towards a safer workplace: promoting healthy work environments through strategic research in memory and behaviour change. In collaboration with WorkCover NSW, psychologists plan to develop new strategies to promote healthy and safe work environments. The researchers will find how to: best motivate people to engage in healthy work practices and obtain comprehensive and accurate information about the causes of accidents.
The emotional face: Effects on orienting, visual search, and categorization. The processing of facial expressions of emotion is essential for successful social functioning however our understanding of how these important signals are processed and of the factors which may impede appropriate processing is lacking. Using a range of converging methodologies drawn from neuroscience, social, and cognitive psychology, this project aims to advance our understanding of the processing of the expressions o ....The emotional face: Effects on orienting, visual search, and categorization. The processing of facial expressions of emotion is essential for successful social functioning however our understanding of how these important signals are processed and of the factors which may impede appropriate processing is lacking. Using a range of converging methodologies drawn from neuroscience, social, and cognitive psychology, this project aims to advance our understanding of the processing of the expressions of two central social emotions, happiness and anger, by delineating the conditions that support or limit it in the general population. This research aims to provide an invaluable knowledge base for subsequent applied research into deficits of emotional expression processing such as occur in autism, anxiety, or old age.Read moreRead less
Perceptual and psychosocial factors associated with individual differences in face identity and face expression processing. What makes one person better or worse than another at recognising faces, or the emotions displayed in those faces? This project examines which aspects of visual perception contribute to these abilities, and their associations with problems such as debilitating social anxiety and young children's anti-social behaviour.
