Summary
Understanding how the brain combines sensory information. The ease with which we perceive the external world belies the complexity involved in integrating different sensory inputs. How does the brain achieve this fundamental operation? The project will address this question using a multidisciplinary approach that combines computational modelling, brain imaging, and psychophysical techniques. The expected outcomes of the project are a better understanding of how people perceive the world through ....Understanding how the brain combines sensory information. The ease with which we perceive the external world belies the complexity involved in integrating different sensory inputs. How does the brain achieve this fundamental operation? The project will address this question using a multidisciplinary approach that combines computational modelling, brain imaging, and psychophysical techniques. The expected outcomes of the project are a better understanding of how people perceive the world through optimal integration of sensory cues. In addition to advancing basic scientific knowledge, the findings will illuminate perceptual anomalies in normally developing children and will provide a foundation for reducing a debilitating side effect of virtual reality systems known as ‘cybersickness’.Read moreRead less
The emotional face. The recognition of emotional facial expressions is essential for successful social functioning. This project will determine how information concerning facial expressions is encoded by the human brain, providing potential insight into situations where this process can fail, such as in old age or autism.
The multitasking brain: training and individual differences. Difficulties with doing two things at once are experienced by everyone, but are particularly common as we get older and in the context of many neurological and psychiatric conditions. This project will examine how training changes the brain to improve multitasking performance and why some individuals are better at multitasking than others.
The genetic basis of human memory. This project will examine the relationship between genetic variation and performance of normal individuals on a comprehensive range of memory test indicators. Results of the study will clarify the genetic basis of human memory and provide a better understanding of this important function.
Investigating differences in decision-making ability in older adults. This project aims to investigate how healthy ageing impacts decision making and its associated neural circuits using computation modelling and neurogenetic methods. Decision-making is a fundamental cognitive ability, allowing us to choose the best course of action. This project will investigate the relationship between genes and decision-making performance across the adult lifespan. Expected outcomes include a deeper understan ....Investigating differences in decision-making ability in older adults. This project aims to investigate how healthy ageing impacts decision making and its associated neural circuits using computation modelling and neurogenetic methods. Decision-making is a fundamental cognitive ability, allowing us to choose the best course of action. This project will investigate the relationship between genes and decision-making performance across the adult lifespan. Expected outcomes include a deeper understanding of how decision-making evolves in healthy ageing, and a tool based on genetic scores and computational modelling to predict an individual's trajectory of cognitive function. This could help identify individuals who are at risk for cognitive decline, which could then inform better interventions.Read moreRead less
Bottlenecks in the brain: a causal role for the frontal-parietal network in multitasking limitations. When considering the information processing demands of modern life (for example, hands-free mobile phone use and driving) it is crucial to understand the mechanisms that underlie the severe multitasking limitations experienced by healthy individuals and clinical groups. This project investigates the brain regions critical for such limits to concentration.
Determining the role of disease avoidance in stigmatisation. The aim of this project is to test a disease avoidance model of stigmatisation. Stigmatisation is characterised by chronic avoidance of a person(s) by other people. Infectious disease may produce an apparently similar form of isolation—disease avoidance. This project proposes that many forms of stigmatisation reflect the activation of this disease avoidance system, which is predisposed to respond to signs of disease, irrespective of th ....Determining the role of disease avoidance in stigmatisation. The aim of this project is to test a disease avoidance model of stigmatisation. Stigmatisation is characterised by chronic avoidance of a person(s) by other people. Infectious disease may produce an apparently similar form of isolation—disease avoidance. This project proposes that many forms of stigmatisation reflect the activation of this disease avoidance system, which is predisposed to respond to signs of disease, irrespective of their accuracy. This will represent a significant shift in thinking about this issue and aims to provide the first empirically based model of stigmatisation as an evolved disposition that causes the exclusion of people who look like they may carry an infectious disease - even if they do not.Read moreRead less
Consequences of inequality on social behaviour and political attitudes. This project aims to reveal how economic inequality shapes dynamics between groups within societies. Income inequality has effects beyond health but its effects on social behaviour and political attitudes are poorly understood. This project will move beyond a focus on the health and well-being costs of income inequality and study its effect on social behaviour and political attitudes. By uncovering these consequences of ineq ....Consequences of inequality on social behaviour and political attitudes. This project aims to reveal how economic inequality shapes dynamics between groups within societies. Income inequality has effects beyond health but its effects on social behaviour and political attitudes are poorly understood. This project will move beyond a focus on the health and well-being costs of income inequality and study its effect on social behaviour and political attitudes. By uncovering these consequences of inequality, the findings are expected to broaden the understanding of growing economic inequality, showing its consequences for the social health of a society and its citizens.Read moreRead less
Sending and responding to messages about climate change: the role of emotion and morality. Climate change represents a moral challenge to humanity, and one that elicits high levels of emotion. This project examines how emotions and morality influence how people send and receive messages about climate change, and does so with an eye to developing concrete and do-able strategies for positive change.
Forensic reasoning and uncertainty: identifying pattern and impression expertise. Maintaining high standards of evidence is vital for an effective justice system and ensuring that innocent people are not wrongly accused. This project aims to improve the reliability of forensic evidence and the value of expert testimony in the criminal justice system by examining forensic decision making.
