Understanding Growth in Emotion Regulatory Flexibility in Emerging Adults. Emerging adults (ages 18-25) are now facing unparalleled social and technological change and the on-going effects of the COVID-19 pandemic. Such demands can be overwhelming and undermine engagement with education and employment, with serious impacts for the individual and society. At the same time, our novel model proposes that the diverse daily adult-like stressors that characterise emerging adulthood can also drive grow ....Understanding Growth in Emotion Regulatory Flexibility in Emerging Adults. Emerging adults (ages 18-25) are now facing unparalleled social and technological change and the on-going effects of the COVID-19 pandemic. Such demands can be overwhelming and undermine engagement with education and employment, with serious impacts for the individual and society. At the same time, our novel model proposes that the diverse daily adult-like stressors that characterise emerging adulthood can also drive growth in flexible emotion regulation when combined with reflection on, and insight into, their own coping processes. Our research expands scientific knowledge by taking the first steps to uncover why some emerging adults increase their ability to flexibly regulate their emotions over this period, whereas others fail to do so.Read moreRead less

This project aims to extend an artificial intelligence algorithm to automatically identify and quantify alcohol prevalence in videos. The project is expected to generate significant new knowledge about alcohol’s exposure in these videos’ social, emotional, and environmental contexts. The expected outcomes include a more efficient and automated method of revealing alcohol pervasiveness and its context in the 1000 most watched videos in Australia, making costly manual coding redundant. Anticipated benefits include enabling governments to better monitor compliance to alcohol product placement guidelines and increased public awareness of the frequency and harmful effects of being exposed to alcohol in videos.Read moreRead less

Summary
Perception and Action in Auditory Scenes (PAAS): Neural, Behavioural, Computational and Mechanical Systems. Auditory scenes are temporal and ephemeral yet pervasively influence human life. How humans negotiate such scenes has not been solved, a fact highlighted by attempts to build machines to respond to speech, warnings etc., in real-world situations with room reverberation, different talkers, and background noise. No one discipline can solve such problems. In this network outstanding researche ....Perception and Action in Auditory Scenes (PAAS): Neural, Behavioural, Computational and Mechanical Systems. Auditory scenes are temporal and ephemeral yet pervasively influence human life. How humans negotiate such scenes has not been solved, a fact highlighted by attempts to build machines to respond to speech, warnings etc., in real-world situations with room reverberation, different talkers, and background noise. No one discipline can solve such problems. In this network outstanding researchers from physical, medical, human, and social sciences with interests in speech, music and audition will provide insights into how humans and machines localize, recognize, interpret and produce auditory events, and advance frontier technologies, e.g., automatic speech recognition, hearing prostheses, auditory monitoring/warning systems.Read moreRead less
Efficacy Of Prism Adaptation For Recovery Of Brain Function In Unilateral Spatial Neglect

Funding Amount
$531,690.00
Summary
Damage to the brain’s attention network causes profound impairments of visual and sensory perception. These deficits are frequently long-lasting, and are a major factor in preventing patients from regaining functional independence. This project will use a combination of behavioural and brain imaging techniques to determine whether a promising new treatment involving visual retraining can improve function and reduce perceptual impairments after unilateral brain lesions.
Prefrontal dopamine in the dynamic processes of learning across lifetime. To facilitate age-specific adaptive action in a changing environment, how we learn changes not only as we grow, but also as we age. However, the neurobiological processes in these age-related changes are poorly studied. This is a significant knowledge gap that needs to be addressed to promote healthy cognitive development and ageing. This research program aims to examine the contribution of prefrontal dopamine and its rece ....Prefrontal dopamine in the dynamic processes of learning across lifetime. To facilitate age-specific adaptive action in a changing environment, how we learn changes not only as we grow, but also as we age. However, the neurobiological processes in these age-related changes are poorly studied. This is a significant knowledge gap that needs to be addressed to promote healthy cognitive development and ageing. This research program aims to examine the contribution of prefrontal dopamine and its receptors D1 and D2 in associative learning and its inhibition at 9 distinct ages spanning development to ageing in male and female rats. The outcomes will provide a new neuroscientific framework to understand learning and memory throughout life, which will foster new research opportunities and inform our education and health.Read moreRead less
Learning from our mistakes: How and when complex decisions fail. The project aims to develop a novel mathematical framework, augmented by simulations and a set of experiments, to study when and how people commit errors. The modern environment bombards us with signals, such as radio and television advertisements as we sit at home or warning lights and car honks as we cross the road.

The project aims to develop a novel mathematical framework, augmented by simulations and a set of experiments, to study when and how people commit errors. The modern environment bombards us with signals, such as radio and television advertisements as we sit at home or warning lights and car honks as we cross the road. Despite years of psychological research, it is not entirely clear how efficiently people cope with increasing amounts of information nor is it clear whether they process multiple signals simultaneously (in parallel) or one after the other (serial). The project offers new measures, based on the rate and pattern of error responses, to supplement the commonly used response times. The combination of a theoretical framework, based on mathematical and computational work, with empirical data to test the models, may deliver a better understanding of human performance and its limitations.Read moreRead less
Organization and Plasticity of Visual Processing in a Miniature Brain. 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.

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
The Role of Colour and Luminance in Spatial Location. How does the brain form our impression of the world? Black and white images appear normal to us. However, colour images without luminance variation have little depth, suggesting that the brain does not process colour in the same way as luminance. A series of fresh experiments examine how colour and luminance are utilised for seeing the depth and position of objects. The results will help us to understand how the first stages of visual process ....The Role of Colour and Luminance in Spatial Location. How does the brain form our impression of the world?

A series of fresh experiments examine how colour and luminance are utilised for seeing the depth and position of objects. The results will help us to understand how the first stages of visual processing in the brain shape our sense of the world, and help develop theories of human vision, as well as animal and machine models of vision.Read moreRead less
