The biological origins underpinning adolescent sleep timing. Notwithstanding cultural and social influences, bedtimes gradually become later during adolescence, suggesting common biological contributions. Reductions in sleep pressure, delays in the 24-hour circadian rhythm, and genetic associations have been implicated, yet comprehensive prospective data from these biological sleep processes are lacking. This project aims to use periodic 'in-lab' assessments to unmask young adolescents' circadia ....The biological origins underpinning adolescent sleep timing. Notwithstanding cultural and social influences, bedtimes gradually become later during adolescence, suggesting common biological contributions. Reductions in sleep pressure, delays in the 24-hour circadian rhythm, and genetic associations have been implicated, yet comprehensive prospective data from these biological sleep processes are lacking. This project aims to use periodic 'in-lab' assessments to unmask young adolescents' circadian rhythm delay and sleep pressure which may predict naturalistic sleep behaviour in their home environment. It is predicted that adolescents who show both low sleep pressure and later circadian delay to possess later bedtimes, thus enhancing knowledge of covert biological mechanisms sabotaging healthy adolescent sleep.Read moreRead less
The role of reward expectancy and reward availability in appetitive motivation. This project will investigate the learning processes that help regulate our desire for rewards such as food and drugs and our decisions about when to pursue those rewards. The results will have implications for our understanding of normal reward motivation as well as interventions for maladaptive behaviours such as gambling and drug-taking.

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.

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 the mechanisms of neuroplasticity enhancing interventions.Read moreRead less
Do family environments influence children's brain development during the transition to adolescence? Late childhood marks the first stages of a wave of brain growth and reorganisation, second only to infancy in terms of its extent and significance. This project will investigate whether brain development during this period is affected by parenting behaviours, which will ultimately inform early intervention and prevention efforts.

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
Attributions for food intake and the control of eating. When explaining why they ate as much as they did in a particular situation, people generally overestimate the role of their hunger or the taste of the food, and underestimate the impact of other factors such as how much food they are served or how much other people eat. This project will examine the motivation behind these mis-attributions, and will also examine the behavioural and emotional consequences of the attributions people make for ....Attributions for food intake and the control of eating. When explaining why they ate as much as they did in a particular situation, people generally overestimate the role of their hunger or the taste of the food, and underestimate the impact of other factors such as how much food they are served or how much other people eat. This project will examine the motivation behind these mis-attributions, and will also examine the behavioural and emotional consequences of the attributions people make for their food intake. By doing so, the proposed research will make a significant contribution to the theoretical understanding of people’s food intake, and can also have practical implications for helping people appropriately regulate their food intake.Read moreRead less
How do social and environmental cues influence food intake? This project will determine how social and environmental factors influence how much people eat. These insights will have theoretical implications for our understanding of what drives people's food intake, and will have practical implications for interventions aimed at curbing excess energy intake, weight gain, and obesity.

This project aims to increase our understanding of what aspects of websites encourage people to engage in risky behaviours. Risk taking in online environments can have significant negative consequences, such as being a victim or perpetrator of cybercrime. This project aims to develop and test a conceptual model to understand the psychological processes underlying risk taking online, focusing on the impact of social cues and specific online environmental cues. Anticipated project outcomes will benefit policy-makers by identifying how sites can be made safer and may also show how to educate people to make safe decisions online and to avoid sites that may encourage them to take risks or engage in anti-social behaviours.Read moreRead less
