This project aims to enhance our understanding of complex social systems by developing empirically testable mathematical models for interactive, dynamic social processes. Models will be developed for such processes as the development of interpersonal and inter-organisational networks, and social influence and diffusion. They will be assessed using new and exacting evaluation techniques. The results will strengthen the mathematical foundation for modelling in the social sciences, and will have immediate application in several diverse domains, including: the structure of networks relevant to disease transmission; the social epidemiology of rural mental health; and the emergence of collective structures in organisations.Read moreRead less

Keeping track: The effect of distraction on attention to moving objects. This is basic research with broad societal implications. We constantly balance the attention demands of achieving a goal (e.g., driving) in the midst of competing environmental demands (e.g., attention-grabbing advertising). Billions of dollars are spent trying to make our roads safer, but basic research is critical to inform policy and design.

This is basic research with broad societal implications. We constantly balance the attention demands of achieving a goal (e.g., driving) in the midst of competing environmental demands (e.g., attention-grabbing advertising). Billions of dollars are spent trying to make our roads safer, but basic research is critical to inform policy and design. There are three main benefits in identifying distractions that impair performance on a task that requires attention to moving objects. It will: (1) develop a method for exploring attention demands on real-world experiences (e.g., driving); (2) inform policy decisions on safer environments; and (3) provide a basis for minimising distractions in environments for people with attentional difficulties.Read moreRead less
The Development of Young Children's Mathematical Abilities: A Longitudinal Analysis. Many people have problems learning maths. Although maths is often seen as an esoteric subject of limited interest, poor maths skills are as great a handicap in education and employment as poor literacy, with similar costs for the individual and society. One cause of poor maths skills is developmental dyscalculia, a disability in which children's understanding of number is affected by underlying cognitive deficit ....The Development of Young Children's Mathematical Abilities: A Longitudinal Analysis. Many people have problems learning maths. Although maths is often seen as an esoteric subject of limited interest, poor maths skills are as great a handicap in education and employment as poor literacy, with similar costs for the individual and society. One cause of poor maths skills is developmental dyscalculia, a disability in which children's understanding of number is affected by underlying cognitive deficits. As yet there is no reliable way of identifying children with dyscalculia or other maths problems. Our research examines children's developing maths competencies as they enter and progress through primary school. Our aim is to develop diagnoses of different maths disabilities, so effective interventions can be implemented.Read moreRead less
Models of Knowledge Restructuring. In a world of rapid change, people must frequently adapt cognitive skills to new technologies. This often requires restructuring of knowledge, from simple initial strategies to increasingly complex ways of mastering the task. This is not always easy and people sometimes resist knowledge restructuring. We present a network model of knowledge restructuring that combines attentional processes with error-driven learning. The model accounts for several existing resu ....Models of Knowledge Restructuring. In a world of rapid change, people must frequently adapt cognitive skills to new technologies. This often requires restructuring of knowledge, from simple initial strategies to increasingly complex ways of mastering the task. This is not always easy and people sometimes resist knowledge restructuring. We present a network model of knowledge restructuring that combines attentional processes with error-driven learning. The model accounts for several existing results and makes predictions that guide the proposed research. Three factors will be examined empirically: (1) the role of directing attention to alternative strategies; (2) the imperfection of existing knowledge; and (3) the complexity of alternative strategies.Read moreRead less
The Perception and Production of Timing in Speaking and Other Actions. The planned research seeks to develop a theoretical account of the mechanism that controls the initiation of spoken utterances and their unfolding in time, both when spoken in isolation and when spoken in rhythmic contexts.

The planned research seeks to develop a theoretical account of the mechanism that controls the initiation of spoken utterances and their unfolding in time, both when spoken in isolation and when spoken in rhythmic contexts. It uncovers the relationship between the perception of speech and its production, and also aims to discover whether the mechanism that controls speech timing is a general property of action or is unique to speech. This work has implications for our understanding of the on-line mechanisms that control speaking and other kinds of action, and thus our understanding of disorders of these human capabilities.Read moreRead less
