Auditory spatial perception during head movements. Orienting to stimuli frequently involves eye and head movements. This improves localisation, yet brings attendant problems (eg, blurring). These problems are well understood in vision, but not in audition, despite evidence for common neural mechanisms. We will examine auditory (and visual) localisation during head movements, showing head movements produce auditory suppression and spatial distortions (analogous to visual saccadic effects). This w ....Auditory spatial perception during head movements. Orienting to stimuli frequently involves eye and head movements. This improves localisation, yet brings attendant problems (eg, blurring). These problems are well understood in vision, but not in audition, despite evidence for common neural mechanisms. We will examine auditory (and visual) localisation during head movements, showing head movements produce auditory suppression and spatial distortions (analogous to visual saccadic effects). This will demonstrate the malleability of auditory spatial perception and the impoverished sensitivity of audition during head and self-motion. Knowledge of these distortions will inform applications such as cockpit design, where orienting to auditory signals is common, and other human/computer interfaces.

Lexical retrieval and reading comprehension: Binding perceptual, lexical and conceptual information in on-line reading. Reading is a complex process that involves integrating sensory information extracted from text with stored memories about word meanings, syntactic structures and general knowledge. Most reading research has focused on the processing of isolated words, but normal reading requires integration processes that are not necessary to recognise single words. This research uses tasks req ....Lexical retrieval and reading comprehension: Binding perceptual, lexical and conceptual information in on-line reading. Reading is a complex process that involves integrating sensory information extracted from text with stored memories about word meanings, syntactic structures and general knowledge. Most reading research has focused on the processing of isolated words, but normal reading requires integration processes that are not necessary to recognise single words. This research uses tasks requiring sentence comprehension and measures of eye movements during reading to investigate how readers retrieve and combine information while reading to comprehend text. It will contribute to developing more comprehensive theories of normal reading that can inform methods of teaching reading and contribute to refinement of text recognition systems.Read moreRead less
Unravelling Leadership Development: Evaluating outcomes, contrasting interventions, and exploring processes. This project investigates how leadership development interventions translate into effective outcomes for organizations. We compare how distinct interventions (transformational leadership vs. 360 degree feedback) and different modes of delivery (face-to-face vs. videoconferencing) lead to change in leader behavior. We investigate the cognitive/motivational mechanisms (e.g., self-efficacy, ....Unravelling Leadership Development: Evaluating outcomes, contrasting interventions, and exploring processes. This project investigates how leadership development interventions translate into effective outcomes for organizations. We compare how distinct interventions (transformational leadership vs. 360 degree feedback) and different modes of delivery (face-to-face vs. videoconferencing) lead to change in leader behavior. We investigate the cognitive/motivational mechanisms (e.g., self-efficacy, perspective-taking) by which these interventions affect leader behavior, as well as the multilevel processes by which change in leader behavior affects team performance and team well-being. The project will provide a more accurate assessment on the return of investment in leadership development, as well as guidance for enhancing the effectiveness of leadership development programs.

The Disproportionate Impact of Negative Contact on Category Salience and Prejudice: Explaining Why Intergroup Interactions Can Be Harmful. The social psychological literature suggests that face-to-face interactions between people of rival groups will reduce mutual prejudice and discrimination. The present research tests the novel prediction that negative face-to-face interactions have a greater probability of worsening broad intergroup relations than positive face-to-face interactions have of im ....The Disproportionate Impact of Negative Contact on Category Salience and Prejudice: Explaining Why Intergroup Interactions Can Be Harmful. The social psychological literature suggests that face-to-face interactions between people of rival groups will reduce mutual prejudice and discrimination. The present research tests the novel prediction that negative face-to-face interactions have a greater probability of worsening broad intergroup relations than positive face-to-face interactions have of improving them. The research will benefit Australia by (a) explaining why intergroup conflict continues to be a key social issue in multicultural Australia despite increased intergroup interactions and by (b) informing policy makers about the social conditions that result in more conflicting intergroup relations as well as the social conditions that result in more harmonious relations.Read moreRead less
Rekindle sexuality after cancer: development and testing of a novel web-based psychoeducational resource for both survivors and their partners. In collaboration with the Cancer Council New South Wales, this project will develop the first web-based psycho-educational resource, Rekindle, that addresses sexual concerns of both survivors and their partners, across all cancer-types, tailored to the unique concerns of each user.
Parenting in an unsteady world across nations. Overinvolved and overcontrolling parenting seems to be on the rise as families are confronted with an unsteady world. This project aims to investigate how overparenting affects youth's achievements and well-being as they transition out of secondary school, and will isolate societal and cultural determinants of overparenting. This project will generate new knowledge on family influences on youth's progress, and will substantially contribute to an exi ....Parenting in an unsteady world across nations. Overinvolved and overcontrolling parenting seems to be on the rise as families are confronted with an unsteady world. This project aims to investigate how overparenting affects youth's achievements and well-being as they transition out of secondary school, and will isolate societal and cultural determinants of overparenting. This project will generate new knowledge on family influences on youth's progress, and will substantially contribute to an existing multinational study to identify macro social-cultural determinants of overcontrolling parenting. Expected outcomes are the generation of new knowledge relevant to family policy and practice within Australia, growth in cross-national collaborations, and new theories and methods.Read moreRead less

This goal of this project is to identify the information the visual system uses to extract the three-dimensional structure and material composition of objects. This project aims to generate an advanced understanding of the information that supports these perceptual abilities and to advance our understanding how this information is learned from exposure to natural scenes. The findings of this work are expected to benefit our understanding of the human visual system, and to provide insights into the information needed to advance the development of deep neural networks (machine learning) that exploit the same information used by humans to guide our behavior and recognize objects and materials.Read moreRead less
Perceiving and misperceiving the causes of optical structure. This project aims to understand the conditions that cause humans to misperceive the shape and surface properties of real-world materials. Most natural materials are translucent to varying degrees, but little is known about how light is transported through them or how such materials are perceived or misperceived. This project will determine the conditions and causes responsible for the misperception of material properties and shape, an ....Perceiving and misperceiving the causes of optical structure. This project aims to understand the conditions that cause humans to misperceive the shape and surface properties of real-world materials. Most natural materials are translucent to varying degrees, but little is known about how light is transported through them or how such materials are perceived or misperceived. This project will determine the conditions and causes responsible for the misperception of material properties and shape, and will offer practical information about what can be done to minimise such misperceptions. The outcomes of the project are expected to lead to new techniques for depicting and manipulating real-world translucent materials in computer graphics, virtual reality, and gaming industries.Read moreRead less

To recognise objects a brain must have an internal representation of most likely object appearance. Two ways in which brains may posses this information include a hard wired template system, and/or the neuroplasticity to learn novel objects. Recent investigations on honeybee vision show that this animal can learn to recognise very difficult objects, although currently we do not know how the miniaturised bee brain manages these tasks. This project will reveal changes that occur in the processing of visual objects by the bee's brain with increasing experience, with potential applications including robotics or building interfaces between sensors and biological systems.Read moreRead less
