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
Attention please! Selective attention and human associative learning. Selective attention allows us to pick useful pieces of information out of the mass of stimulation that we're faced with every moment. This project investigates how what we've previously learnt about the significance of events influences whether we'll pick them out as useful in future, and how this might be impaired by old age or mental disorder.

Summary
How Do Our Past Decisions Affect Our Present Decisions? – An Innovative Model. Decisions under time pressure made in the past have a tendency to affect our current decisions. This phenomenon is often termed ‘sequential effects’. Typically, sequential effects are explained by positing the existence of a psychological mechanism that is specifically aimed at resolving conflicting information. The aim of this project is to develop a computational model that produces sequential effects naturally. Inn ....How Do Our Past Decisions Affect Our Present Decisions? – An Innovative Model. Decisions under time pressure made in the past have a tendency to affect our current decisions. This phenomenon is often termed ‘sequential effects’. Typically, sequential effects are explained by positing the existence of a psychological mechanism that is specifically aimed at resolving conflicting information. The aim of this project is to develop a computational model that produces sequential effects naturally. Innovatively, this model would remove the need for an explicit conflict monitoring mechanism. This project is significant because it progresses our understanding of how humans deal with conflict. The expected outcome is a comprehensive, quantitative account of sequential effects in human decision making.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
Decoding change of mind decisions and errors from brain activity in humans. This project intends to provide new insights into how the brain changes a decision to achieve better outcomes. Decision-making is rarely optimal, and in a dynamic world people must often change their initial decisions in order to avoid consequential errors. This project aims to investigate the neural mechanisms underlying such change-of-mind decisions and decision errors in humans. To this end, it plans to use novel deco ....Decoding change of mind decisions and errors from brain activity in humans. This project intends to provide new insights into how the brain changes a decision to achieve better outcomes. Decision-making is rarely optimal, and in a dynamic world people must often change their initial decisions in order to avoid consequential errors. This project aims to investigate the neural mechanisms underlying such change-of-mind decisions and decision errors in humans. To this end, it plans to use novel decoding techniques to predict the evolution of change-of-mind decisions from brain activity while decisions unfold. This approach would clarify how quality of information, effort, and reward are integrated at a neural level to bias people towards changing their decisions. The expected results would provide an improved understanding of the neural dynamics of errors and how the brain corrects decisions online to achieve better outcomes.Read moreRead less

The principal expected outcomes are insights into the factors that guide superannuation choice, build trust with superannuation providers, and ensure clear and effective communication with members.Read moreRead less
The benefits of sociality: understanding the relationship between cooperation, cognition and fitness. Cooperation may present unique cognitive challenges. Individuals perform behaviours that provide fitness benefits to others, exposing themselves to risk. The need to monitor the behaviour of group members, recognise suitable cooperative partners, and make corresponding behavioural adjustments to maximize the benefits of cooperation, may therefore be an important driver of social evolution. The r ....The benefits of sociality: understanding the relationship between cooperation, cognition and fitness. Cooperation may present unique cognitive challenges. Individuals perform behaviours that provide fitness benefits to others, exposing themselves to risk. The need to monitor the behaviour of group members, recognise suitable cooperative partners, and make corresponding behavioural adjustments to maximize the benefits of cooperation, may therefore be an important driver of social evolution. The relevance of understanding the relationship between cognition and cooperation is in how it affects the fitness of individuals and the stability of cooperation. This project aims to unveil this relationship by conducting one of the first comprehensive studies of the selective benefits of cognitive ability in a wild, cooperative bird species.Read moreRead less

Decoding unstable decision preferences from brain activity. We often have to make decisions despite lacking clear preferences. This leaves us susceptible to biases from stimuli and information in our environment. This project investigates how simple, perceptual decisions and financial decisions are influenced by contextual information.

We often have to make decisions despite lacking clear preferences. This leaves us susceptible to biases from stimuli and information in our environment. This project investigates how simple, perceptual decisions and financial decisions are influenced by contextual information. The project will combine state-of-the-art neuroimaging technology with machine learning methods to develop a novel decision-decoding toolbox that directly predicts decision outcomes from brain activity. This will allow investigation of how decision encoding in the brain changes under the influence of contextual information, and will provide the basis for developing an advanced model for human decision-making in real-life situations.Read moreRead less
