The impact of light intensity during night shifts on circadian adaptation. Each year, the sleep loss and body clock disruption caused by night work cost the Australian economy $2–3 billion in lost productivity, impaired well-being, and poor health. Current regulations limit sequences of night shifts to a maximum of four in a row. However, recent research suggests that this blanket limit may be a well-intentioned, but ill-informed, policy.

Each year, the sleep loss and body clock disruption caused by night work cost the Australian economy $2–3 billion in lost productivity, impaired well-being, and poor health. Current regulations limit sequences of night shifts to a maximum of four in a row. However, recent research suggests that this blanket limit may be a well-intentioned, but ill-informed, policy. As a result, we may be inadvertently increasing, rather than reducing, work-related fatigue. This project will determine whether longer sequences of night shifts may reduce sleep loss and body clock disruption in some workplaces. The project will provide the evidence base for a more nuanced approach to fatigue regulation and a safer workplace for Australian shiftworkers. Read moreRead less
Feeling and thinking: affect, implicit social cognition and behaviour. Although affect plays a major role in human affairs, the psychological mechanisms linking affect to thinking and behaviour remain incompletely understood. This project will investigate the influence of affective states on implicit cognitive processes and subsequent social behaviours.

Although affect plays a major role in human affairs, the psychological mechanisms linking affect to thinking and behaviour remain incompletely understood. This project will investigate the influence of affective states on implicit cognitive processes and subsequent social behaviours. The project aims to develop and to test an innovative information processing theory linking affect to implicit cognition, and apply new experimental methods to measure the cognitive and behavioural consequences of affect. Studies will also explore the applied consequences of affect infusion for real-life social behaviours with expected implications for health, clinical, organisational, and educational outcomes.Read moreRead less

This project aims to investigate the neurobiological and neuropsychological determinants of habit formation and change in the context of ageing, by combining cutting-edge techniques in psychology, behavioural neuroscience and neuroimaging. This research expects to generate new knowledge in the area of automatic habits and behaviour change, by investigating how these processes are affected in ageing using an interdisciplinary approach. Expected outcomes include a new, comprehensive model of habit formation and change in ageing. This should provide significant benefits, as it will lay the foundation for future habit-based behaviour change interventions to support older people to age well and productively.Read moreRead less
Functional impact of high fat and high sugar diets on memory encoding. This project aims to determine the functional mechanisms of how fats and sugar affect neuronal processes vital for learning and memory. Expected outcomes will define the neural mechanisms underpinning cognitive changes in emotional and spatial memory encoding, and how these relate to brain and metabolic parameters. This will provide benefits by unveiling the possible consequences of dietary fat and sugar on the brain, and th ....Functional impact of high fat and high sugar diets on memory encoding.

Responding to the challenge of identity change. This project aims to advance our understanding of factors that promote successful adjustment to collective-level change, which is imperative for well-being and the fabric of society.

This project aims to advance our understanding of factors that promote successful adjustment to collective-level change, which is imperative for well-being and the fabric of society. The psychological and financial cost of not understanding these dynamics is significant, and is at the forefront of concerns in organisational, educational, community and national contexts. This project will help elucidate the complexities of collective-level change and adjustment to such change, providing benefits to communities, organisations and policy makers. The project builds on The Social Identity Model of Identity Change (SIMIC), a theoretical approach which helps to understand how people might effectively cope with change; it forms the basis of an ambitious and integrated theoretical program of research that will examine SIMIC predictions in novel contexts.Read moreRead less
Paving the way for ultra-long haul flights: strategies to mitigate jetlag. This project aims to develop and test strategies to mitigate jetlag, founded on biophysical modelling of circadian rhythms. It sets out to quantify the speed of circadian adaptation of sleep, alertness, and metabolism after transmeridian travel and to maximise speed of adaptation via optimised timing of light exposure, food, and exercise in-flight and on-the-ground. Expected outcomes include powerful models for jetlag str ....Paving the way for ultra-long haul flights: strategies to mitigate jetlag. This project aims to develop and test strategies to mitigate jetlag, founded on biophysical modelling of circadian rhythms. It sets out to quantify the speed of circadian adaptation of sleep, alertness, and metabolism after transmeridian travel and to maximise speed of adaptation via optimised timing of light exposure, food, and exercise in-flight and on-the-ground. Expected outcomes include powerful models for jetlag strategies, ready for application in air travel. The project will directly inform Qantas’ operations for ultra-long haul flights and their international network more broadly. Project outcomes will benefit society and the economy through improving travellers’ alertness, sleep, and reducing the risk of fatigue-related accidents.Read moreRead less

This project will examine Australian parents’ number one concern about their children’s health and behaviour – their interactions with electronic screens. Current screen time guidelines are based on low-quality evidence and lack the nuance required to address this complex issue. This project will use innovative technology to resolve these weaknesses. Wearable cameras will measure what children are doing on screens, and where, when, and how long they are doing it. The project will also investigate how screen time impacts children’s development and how it is influenced by their environment. This evidence will benefit children by improving screen time guidelines, and help parents understand the impact of screen time on children’s development.

Things don’t always go better with Coke. This project aims to test whether soft drink use is governed partly by automatic processes (cognitive biases) that operate largely outside of conscious control. In so doing, the project expects to generate a new conceptual understanding of the mechanisms that drive the overconsumption of soft drinks. Expected outcomes include theoretical innovation, new research methodologies, and accessible cost-effective technologies for reducing excessive sugar intake ....Things don’t always go better with Coke.

This project aims to investigate how attention is automatically drawn towards stimuli that signal rewarding outcomes. Sometimes, the attention afforded to these reward cues (how we’ve learned to respond) is in direct conflict with our intentions (how we would like to behave). This project expects to generate new knowledge regarding how and when attentional distraction by reward is more automatic in nature as opposed to being inhibited by cognitive control processes. Expected outcomes of this project include better understanding of the learning processes that shape attentional responses, the neural correlates of the conflict that can arise and the link to behavioural outcomes (e.g., food choices).

Circadian photoreceptor sensitivity and impacts of modern lighting on sleep. Light has powerful non-visual effects, including effects on sleep. These non-visual effects are mediated by cells in the eye that are most sensitive to blue light. There are large individual differences in sensitivity to non-visual effects of light that are not understood and that would give great insight into suboptimal sleep, which has become widespread in modern society.

These non-visual effects are mediated by cells in the eye that are most sensitive to blue light. There are large individual differences in sensitivity to non-visual effects of light that are not understood and that would give great insight into suboptimal sleep, which has become widespread in modern society. This study will be the first systematic examination of individual differences in the effect of blue light on sleep and will uncover how alterations in the gene responsible for the effects of blue light on sleep (OPN4) contribute to these differences. This will lead to scalable individualised solutions to the unmet problem of how modern light environments impact sleep.Read moreRead less
