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

Contemporary life engagement and cognitive resilience in ageing. The aim of this Laureate Fellowship is to make a significant advance in our understanding of cognitive ageing through the adult life course by discovering how contemporary lifestyles and experience impact on cognitive resilience and cognitive function. Population ageing is occurring globally, creating an urgent need for evidence to inform strategies to promote ageing well and productively. Through assessment of adults aged 18-90 (a ....Contemporary life engagement and cognitive resilience in ageing. The aim of this Laureate Fellowship is to make a significant advance in our understanding of cognitive ageing through the adult life course by discovering how contemporary lifestyles and experience impact on cognitive resilience and cognitive function. Population ageing is occurring globally, creating an urgent need for evidence to inform strategies to promote ageing well and productively. Through assessment of adults aged 18-90 (across the life course), this project will evaluation the impact of technology, life space and sensory function on brain structure and function, and cognition. Intended benefits include provision of evidence to inform interventions and policies that optimize cognitive resilience and reduce cognitive decline.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.

The influence of features of the online environment on risk taking. 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 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

Summary
Does obesity alter the associations to food related cues, contexts and responses? Obesity is increasing dramatically in the developed world. The reasons for this are unclear, however the abundance of cheap, palatable food is clearly a contributing factor. Studies suggest differences arise in the processing of food rewards between overweight and lean individuals and the way they respond to food associated cues. This indicates that food associated cues may be more likely to evoke feeding behaviour ....Does obesity alter the associations to food related cues, contexts and responses? Obesity is increasing dramatically in the developed world. The reasons for this are unclear, however the abundance of cheap, palatable food is clearly a contributing factor. Studies suggest differences arise in the processing of food rewards between overweight and lean individuals and the way they respond to food associated cues. This indicates that food associated cues may be more likely to evoke feeding behaviours in absence of metabolic needs, therefore contributing to over eating that leads to obesity. This project will determine how rats, exposed to a model of our obesogenic western diet, process distinct cues and contexts associated with food rewards and control value driven responses to gain food rewards.Read moreRead less
Open(ing up) goals in physical activity: What works, when, and for whom? This project aims to advance knowledge of open goals as a new goal-setting approach to optimise the adoption and maintenance of physical activity among insufficiently active individuals. This project expects to generate substantive insights into the mechanisms that explain why, when, and for whom open goals are particularly beneficial in this population. Expected outcomes include a theory of open goals that will inform phys ....Open(ing up) goals in physical activity: What works, when, and for whom? This project aims to advance knowledge of open goals as a new goal-setting approach to optimise the adoption and maintenance of physical activity among insufficiently active individuals. This project expects to generate substantive insights into the mechanisms that explain why, when, and for whom open goals are particularly beneficial in this population. Expected outcomes include a theory of open goals that will inform physical activity promotion efforts, with the potential for broad population-level dissemination and scale-up. Significant benefits include the ability to set physical activity goals that are enjoyable and intrinsically motivating to pursue, while also avoiding detrimental effects of current practice (eg high failure rates).Read moreRead less
Uncertainty and response control in the prefrontal cortex. This project will identify how complex behaviours come to be performed habitually. It is proposed that statistical certainty in the learning environment is a key determinant of automatic behaviour, that detection of uncertainty can restore voluntary control of behaviour and that this is an important function of the prefrontal cortex of the brain.
How people learn inhibitory associations. This project aims to combine insights from associative and cognitive theories to investigate how people acquire, represent and generalise knowledge about inhibitory, or preventative, relationships. The project intends to use novel methods to assess the inhibitory causal structures inferred by individual participants, expected to include direct outcome prevention, modulation of a causal relationship, and configural learning. This project should expand our ....How people learn inhibitory associations.

The project intends to use novel methods to assess the inhibitory causal structures inferred by individual participants, expected to include direct outcome prevention, modulation of a causal relationship, and configural learning. This project should expand our understanding of the mechanisms of human associative learning. The project should benefit and inform clinical interventions based on identifying and normalising maladaptive learned associations.Read moreRead less
