Unifying models of reasoning and memory. Inductive reasoning involves extending current knowledge to new contexts and is therefore essential for effective learning, decision-making and innovative problem solving. This project extends our understanding of this crucial cognitive skill by developing a new and more comprehensive model of human induction. It also examines patterns of inductive development during the pre-school and primary school years, laying the foundation for the development of bet ....Unifying models of reasoning and memory.

This project extends our understanding of this crucial cognitive skill by developing a new and more comprehensive model of human induction. It also examines patterns of inductive development during the pre-school and primary school years, laying the foundation for the development of better methods for teaching children how to reason.Read moreRead less
Category learning and conceptual change in children. Fundamental to children's cognitive development is the ability to form concepts and generalize beyond direct experience. This project examines the effect of pre-existing beliefs and new empirical observations on concept learning by children. The cognitive processes involved when children of various ages integrate these different sources of information to form new concepts will be investigated in several knowledge domains. In addition to addre ....Category learning and conceptual change in children. Fundamental to children's cognitive development is the ability to form concepts and generalize beyond direct experience. This project examines the effect of pre-existing beliefs and new empirical observations on concept learning by children. The cognitive processes involved when children of various ages integrate these different sources of information to form new concepts will be investigated in several knowledge domains. In addition to addressing key theoretical questions about the role of exemplar diversity and sub-typing processes in concept learning the project will develop and evaluate innovative techniques for teaching science concepts to young children.Read moreRead less
The development of causal induction. An ability to reason inductively is an essential prerequisite for effective learning and decision-making. Inductive thinking is also closely related to creativity and innovation. By acquiring a better understanding of how such reasoning develops we will contribute to the enhancement of techniques that help children to learn and refine inductive reasoning skills, and will provide a foundation for the development of programs to assist children who have partic ....The development of causal induction.

By acquiring a better understanding of how such reasoning develops we will contribute to the enhancement of techniques that help children to learn and refine inductive reasoning skills, and will provide a foundation for the development of programs to assist children who have particular problems in inductive reasoning and generalisation (i.e. those with autism or an intellectual disability).Read moreRead less
Ageing and self-regulation. Australia is faced with an ageing population, and thus an increasingly important national goal is ageing well and ageing productively. Our preliminary research suggests that self-regulation may be a significant problem for older Australians. The proposed research will provide a clearer picture of when and why older adults have difficulties regulating their behaviour, and which older adults are particularly susceptible to lapses in self-control. If older adults do hav ....Ageing and self-regulation. Australia is faced with an ageing population, and thus an increasingly important national goal is ageing well and ageing productively. Our preliminary research suggests that self-regulation may be a significant problem for older Australians. The proposed research will provide a clearer picture of when and why older adults have difficulties regulating their behaviour, and which older adults are particularly susceptible to lapses in self-control. If older adults do have difficulties self-regulating, and if these self-regulation failures incur health, financial and social costs, by gaining a clearer understanding of this problem, the proposed research will take an important step in improving the lives of older Australians.

Everyday cognition in older adulthood: Mechanisms contributing to the age-prospective memory paradox. Australia is faced with an ageing population, and thus an increasingly important goal is ageing well and ageing productively. The proposed research will clarify why older adults perform extremely well on prospective memory (PM) tasks based in everyday environments, but very poorly on PM tasks that take place in the controlled situation of the laboratory. Advancing our understanding of why this ....Everyday cognition in older adulthood: Mechanisms contributing to the age-prospective memory paradox. Australia is faced with an ageing population, and thus an increasingly important goal is ageing well and ageing productively. The proposed research will clarify why older adults perform extremely well on prospective memory (PM) tasks based in everyday environments, but very poorly on PM tasks that take place in the controlled situation of the laboratory. Advancing our understanding of why this 'paradoxical' pattern of age effects occurs will help clarify how other aspects of everyday cognition in older adulthood may be optimised, and consequently take an important step in improving the lives of older adults. The results will also inform development of rehabilitation strategies for clinical groups who present with PM difficulties. Read moreRead less
Developing and testing a mnemonic theory of odour perception. This project studies how odours are perceived and remembered. Its theoretical framework is a model of olfaction containing a central assumption that past experience of an odour determines how it is perceived and how well it can be discriminated from other odours. Thus, the project tests predictions that discrimination between odours depends on age and on culture-specific experience, as well as other aspects of the model, like discre ....Developing and testing a mnemonic theory of odour perception. This project studies how odours are perceived and remembered. Its theoretical framework is a model of olfaction containing a central assumption that past experience of an odour determines how it is perceived and how well it can be discriminated from other odours. Thus, the project tests predictions that discrimination between odours depends on age and on culture-specific experience, as well as other aspects of the model, like discrete memory systems, imagery and different ways of learning about odours. The project's outcome will be its integration of odour perception, learning and memory, into the first comprehensive information-processing model of human olfaction. Read moreRead less
The Development of Speed Skill. The power function has been the unquestioned law linking practice to human response time for 30 years and is the basis for all current theories of human skill acquisition. Our recent work has overturned the power law in favour of an exponential law. This project uses a combination of computer simulation and experimentation with both adults and children to determine the generality of the exponential law and to develop theory that can accommodate it. Developmental ....The Development of Speed Skill. The power function has been the unquestioned law linking practice to human response time for 30 years and is the basis for all current theories of human skill acquisition. Our recent work has overturned the power law in favour of an exponential law. This project uses a combination of computer simulation and experimentation with both adults and children to determine the generality of the exponential law and to develop theory that can accommodate it. Developmental and practice effects will be compared in four fundamental cognitive tasks and new estimation methodologies tested, resulting in quantifiable improvements in education and training practices.Read moreRead less

Disgust as a psychosocial defence against infectious disease. Globally, around 1 in 4 deaths result from infectious disease. Humans have evolved two basic means to combat this - an immune system and behaviours to avoid getting sick. This project examines one such behaviour, disgust, and aims to determine its role in disease avoidance. Studying disgust can lead to novel insights into behaviours as diverse as risky sexual decision-making and illness-related stigmatisation (e.g. of people with AID ....Disgust as a psychosocial defence against infectious disease. Globally, around 1 in 4 deaths result from infectious disease. Humans have evolved two basic means to combat this - an immune system and behaviours to avoid getting sick. This project examines one such behaviour, disgust, and aims to determine its role in disease avoidance. Studying disgust can lead to novel insights into behaviours as diverse as risky sexual decision-making and illness-related stigmatisation (e.g. of people with AIDS or cancer). Disgust can also be used to directly improve human health. For example, it can be exploited to boost hand hygiene. If widely applied, this simple measure could annually save an estimated 1.5 million children's lives, reduce rates of flu, colds, food poisoning and hospital acquired infections.Read moreRead less

Australia is faced with an ageing population, and thus an increasingly important national goal is ageing well and ageing productively. The proposed research will extend our preliminary findings on ageing and social inappropriateness to provide a clearer picture of when and why this occurs, and among whom. The proposed research will also examine the mental and physical health consequences of social inappropriateness longitudinally. If cognitive losses do lead to social losses, with attendant negative health consequences, by gaining a clearer understanding of this problem, the proposed research will take an important step in improving the lives of older adults.Read moreRead less
