The desire for knowledge: Neural mechanisms of information-seeking. This project aims to determine the mechanisms that drive individuals to seek out information, and to characterise the neural processes that underlie how that information is valued. The project tests the idea that information is represented in the brain as a form of reward.

This project aims to determine the mechanisms that drive individuals to seek out information, and to characterise the neural processes that underlie how that information is valued. The project tests the idea that information is represented in the brain as a form of reward. The results are expected to contribute significant mechanistic insights at the level of brain and behaviour on the nature of information value. This is likely to have wide-ranging implications across multiple domains of human endeavour, including education, work-place efficiency, policy development, and consumer behaviour.Read moreRead less

A Brain-Behaviour Model of Decision-Making Under Distraction. People make thousands of decisions each day, such as judging whether it is safe to cross the street at a busy intersection. This project aims to investigate how decision-making is impacted when a person is temporarily distracted, for example when receiving a text message alert from one’s phone.

People make thousands of decisions each day, such as judging whether it is safe to cross the street at a busy intersection. This project aims to investigate how decision-making is impacted when a person is temporarily distracted, for example when receiving a text message alert from one’s phone. By combining recordings of brain activity with cutting-edge mathematical modelling techniques, this project expects to develop a novel theoretical framework that captures the effects of distraction on brain networks that underpin human decision-making performance. This knowledge should be highly beneficial for developing informed policies that reduce effects of distraction and preserve decision-making capacity in safety critical situations.Read moreRead less
Expecting the unexpected: how people prioritise predictability. This project aims to investigate how people represent and use information about unpredictability in their environment. Seeing too much predictability is problematic, but seeing too little can also be a problem, for example inappropriate "learned helplessness" can occur, whereby people feel disempowered because the world is seen as random. Recent findings demonstrated a bias in fundamental learning that may maintain these inappropria ....Expecting the unexpected: how people prioritise predictability. This project aims to investigate how people represent and use information about unpredictability in their environment. Seeing too much predictability is problematic, but seeing too little can also be a problem, for example inappropriate "learned helplessness" can occur, whereby people feel disempowered because the world is seen as random. Recent findings demonstrated a bias in fundamental learning that may maintain these inappropriate beliefs about unpredictability. This bias is not anticipated by formal theories of learning. The project will investigate how this bias is brought about by first formalising a novel theory of fundamental learning and then systematically testing its assumptions.Read moreRead less

Summary
From known to unknown: Individual differences in associative generalisation. This project aims to investigate how and why individuals differ in the way that they generalise from past experiences to novel situations. The goal of the project is to develop an innovative and formal model capable of predicting how a given individual will generalise based on their beliefs and personal traits, and to better understand how people behave when there are multiple conflicting ways to generalise. The expecte ....From known to unknown: Individual differences in associative generalisation. This project aims to investigate how and why individuals differ in the way that they generalise from past experiences to novel situations. The goal of the project is to develop an innovative and formal model capable of predicting how a given individual will generalise based on their beliefs and personal traits, and to better understand how people behave when there are multiple conflicting ways to generalise. The expected outcomes of the project are a better understanding and measurement of generalisation, a fundamental psychological process. The outcomes of this project can be used to benefit the development of clinical treatment for anxiety disorders, of which overgeneralisation of fear responses is a defining feature.

The role of inductive reasoning in generalization of associative learning. This project seeks to develop a better understanding of how learning is generalised to novel stimuli. Learning about associations around us helps us to obtain resources and minimise threat. A critical task for the learner is how far to extrapolate this knowledge: too little generalisation reduces the benefits of learning and too much risks distraction and maladaptive responding. Recent evidence has shown an important role ....The role of inductive reasoning in generalization of associative learning. This project seeks to develop a better understanding of how learning is generalised to novel stimuli. Learning about associations around us helps us to obtain resources and minimise threat. A critical task for the learner is how far to extrapolate this knowledge: too little generalisation reduces the benefits of learning and too much risks distraction and maladaptive responding. Recent evidence has shown an important role for reasoning processes in human associative learning. This project aims to apply insights from the inductive reasoning literature to study the role of hypothesis and category induction in generalisation of associative learning. The results are expected to have important implications for our understanding of associative learning and generalisation which may inform techniques to promote adaptive generalisation in fields such as education, training and clinical practice.Read moreRead less

Climate change is a significant contemporary issue, and communicating the complexities of the terminology and the data is a major modern challenge. This project will apply principles of cognitive and social psychology to determine the most effective methods for promoting an understanding of the scientific dimensions of the issue. The research is significant because it provides a coherent theoretical framework for identifying the psychological mechanisms underlying cognition and commitment at both an individual and collective level. The outcome will be a body of evidence that will inform strategies and policies for communication of complex scientific questions.Read moreRead less
Using language to predict cognitive outcomes in old age. This project aims to understand the relationship between linguistic complexity metrics and cognitive decline in old age. The project will test the hypothesis that high linguistic complexity scores reflect the ability to strategically optimise processing in the face of age-related reductions in processing capacity. By studying the relation between complexity scores and real-time information processing (measured via electroencephalography) a ....Using language to predict cognitive outcomes in old age. This project aims to understand the relationship between linguistic complexity metrics and cognitive decline in old age. The project will test the hypothesis that high linguistic complexity scores reflect the ability to strategically optimise processing in the face of age-related reductions in processing capacity. By studying the relation between complexity scores and real-time information processing (measured via electroencephalography) across the adult lifespan (20–80 years), this project will develop a simple and accurate marker of the individual balance between processing capacity and strategy. This project has the potential to increase quality of life for the elderly and reduce costs of age-related cognitive impairment.Read moreRead less
Unifying decisions from experience and description. The project aims to answer an enduring question: are separate theories required for decisions from experience and description? For some decisions, potential outcomes and probabilities are known – a gamble offering a 10 per cent chance to win $100 or a 90 per cent chance of nothing, for example. For many others, there is no ‘look-up table’ of probabilities and outcomes and so we must learn them via experience. Intriguingly, risky choices made on ....Unifying decisions from experience and description. The project aims to answer an enduring question: are separate theories required for decisions from experience and description? For some decisions, potential outcomes and probabilities are known – a gamble offering a 10 per cent chance to win $100 or a 90 per cent chance of nothing, for example. For many others, there is no ‘look-up table’ of probabilities and outcomes and so we must learn them via experience. Intriguingly, risky choices made on the basis of described or experienced information differ markedly. This project examines why this divergence occurs. The project plans to test an innovative approach that unifies both types of decisions into a single theoretical framework and provides a suite of empirical and modelling results.Read moreRead less
Toward a unified account of adaptive decision making: learning to search, stop and decide. The quality of decision making, our own and those with influence over us is a fundamental concern. The centrality of this issue means that it is crucial to understand the cognitive processes underlying human decision making. This project will deliver new insights into these processes and make key recommendations for improving decision making.
