Make up your mind! - Dissociating the roles of orbitofrontal cortex and striatum in human decision making. How we make everyday decisions is a crucial behaviour of humans but the underlying processes in the brain are still poorly understood. This project will investigate what the roles of specific brain regions are in human decision making, which enable us to gain a better understanding of how these brain structures contribute to our decisions.
A new training approach to address the novice driver problem. This project aims to develop a new approach to driver training. For the second consecutive year, road deaths in Australia have increased by 150 from 2014 to 2016. The increase in deaths was greatest for young drivers between the ages of 17-25 years, who remain over-represented in road deaths. The majority of these deaths occur in the first few months after licensing. This project expects to generate new knowledge, where the focus is o ....A new training approach to address the novice driver problem. This project aims to develop a new approach to driver training. For the second consecutive year, road deaths in Australia have increased by 150 from 2014 to 2016. The increase in deaths was greatest for young drivers between the ages of 17-25 years, who remain over-represented in road deaths. The majority of these deaths occur in the first few months after licensing. This project expects to generate new knowledge, where the focus is on developing young driver’s cognitive skills about speed choice through the provisions of a training program that focuses on feedback. The results will have the potential to be used by road authorities and driver training organisations to improve road safety.Read moreRead less
Context dependent flower choice in honey bees. This project aims to discover the strategies honey bees use when choosing between multiple flowers. The choices that honey bees make about which flowers to visit and which to avoid has significant impacts on crop yields, the spread of invasive weeds, and the conservation of native plants. This project expects to generate new knowledge in the fields of behavioural and pollination ecology through a combination of field experiments and modelling.

The choices that honey bees make about which flowers to visit and which to avoid has significant impacts on crop yields, the spread of invasive weeds, and the conservation of native plants. This project expects to generate new knowledge in the fields of behavioural and pollination ecology through a combination of field experiments and modelling. Expected outcomes of this project include enhanced capacity in the field of pollination ecology, and new insight into flower preferences in the world’s most important commercial pollinator. This should provide significant benefits to food production and security as one third of the world’s crops benefit from insect pollination.Read moreRead less
Risky Futures: Toward a Computational Process Model of Risky Inter-Temporal Choice. A lot is known about people’s preferences. People like their rewards now. Most would prefer $10 today than $20 in one month. Risk is also unattractive; a certain $10 is more attractive than a 50 per cent chance of receiving $25. Surprisingly, much less is known about the interaction between delay and risk. That is, relatively little is known about whether people prefer $10 now, or a 50 per cent chance of $50 in ....Risky Futures: Toward a Computational Process Model of Risky Inter-Temporal Choice. A lot is known about people’s preferences. People like their rewards now. Most would prefer $10 today than $20 in one month. Risk is also unattractive; a certain $10 is more attractive than a 50 per cent chance of receiving $25. Surprisingly, much less is known about the interaction between delay and risk. That is, relatively little is known about whether people prefer $10 now, or a 50 per cent chance of $50 in one month. This project will use a combination of experiments and cognitive modelling to examine all three types of choice. The outcome will be a novel computational model that will elucidate the complex interaction between delay and risk, thereby answering an enduring question in the literature: are risk and delay psychologically equivalent?Read moreRead less
I like you and I just can't help it: Explaining automatic affective responses. Our automatic affective responses are crucial in determining how we behave particularly in situations where there is little conscious deliberation. These automatic responses have been implicated in dysfunctional behaviours such as unhealthy food choices and racial bias. However very little research has investigated the psychological processes responsible for the formation of these automatic affective responses. The ai ....I like you and I just can't help it: Explaining automatic affective responses. Our automatic affective responses are crucial in determining how we behave particularly in situations where there is little conscious deliberation. These automatic responses have been implicated in dysfunctional behaviours such as unhealthy food choices and racial bias. However very little research has investigated the psychological processes responsible for the formation of these automatic affective responses. The aim of this project is to investigate the role of conditioning and cognitive processes in the formation and expression of automatic affective responses. This will allow for the development of novel interventions targeting automatic responses which contribute to dysfunctional behaviour. Read moreRead less
The Neural Bases of Decision-Making. The smooth integration of cognitive and emotional processes is necessary for everyday decisions. Dysfunction in this integrative capacity accompanies dementia, neurodegenerative conditions and major psychiatric disorders.

The smooth integration of cognitive and emotional processes is necessary for everyday decisions. Dysfunction in this integrative capacity accompanies dementia, neurodegenerative conditions and major psychiatric disorders. This project seeks to understand the neural bases of this integration in normal decision-making using cutting edge behavioural, cellular, molecular and genetic tools to map the neural system, circuit and cellular processes controlling the selection, evaluation and choice of goal-directed actions. Such actions can, with continued practice, transition into relatively inflexible habits. Thus, this project aims to investigate the neural processes that mediate this transition and how actions and habits interact in normal decision-making.Read moreRead less
Predicting Behaviour from Brain Representations.

This project aims to advance our understanding of how perceptual information is represented in the human brain and to link the structure of perceptual brain representations to human behaviour. The project plans to use complementary methods for recording brain activity (human neuroimaging and primate single-cell neurophysiology) and cutting-edge analytic techniques to generate a predictive model of behaviour based on the structure of perceptual brain representations. It is anticipated that the results will significantly advance the field of cognitive neuroscience by providing a novel empirical framework for understanding how brain representations are predictive of behaviour.Read moreRead less

The dynamic world around us means we need to constantly adjust our decisions in light of ever-changing influences, both external (weather, traffic ...) and internal (fatigue, learning ...). This project aims to understand how these changes affect performance. This will have significance for basic science, and also practical benefits for applied psychology. This project will examine the dynamic nature of psychological processes in a range of settings: simple decisions, consumer decisions, human-machine interactions, and team performance. Theory development will lead to improved understanding of underlying cognitive processes, and transforms the measurement of decisions, which is important for applied psychological investigations.

Learning and choosing in a complex world. How do people make choices in a complex world? Making good choices requires expertise, but people must often forego rewards in order to acquire this knowledge. This is the essence of an "explore-exploit dilemma": to maximise rewards across a long time frame, people must take the time to explore and learn now. Empirically, this project aims to unify much of the existing psychological literature and extend it to cover richer, more complex problems. Theoret ....Learning and choosing in a complex world.

This project aims to improve our understanding of individual decision making in financial markets and its implications for macro-economic stability. Using laboratory and internet experiments, models of adaptive choice behaviour will be developed and validated. The project will help to gain insight into how past information, and the way it is presented, affects investment decisions, which individual characteristics matter for decisions, and how this behaviour translates into the evolution of aggregate macro-economic variables. The expected outcomes of the project will have the potential to improve the design of tools for better individual financial decision making, to stabilize volatile markets and to enhance economic welfare.Read moreRead less
