How the brain produces speech: Neuronal oscillations to neuromodulation. Speech is crucial for facilitating human communication through language, yet there is a lack of clarity about where, when and what type of activity occurs in the brain during key stages of production. This project will use intracranial recordings to characterise neuronal oscillations in combination with direct electrical stimulation, functional neuroimaging and non-invasive brain stimulation to establish critical areas and ....How the brain produces speech: Neuronal oscillations to neuromodulation. Speech is crucial for facilitating human communication through language, yet there is a lack of clarity about where, when and what type of activity occurs in the brain during key stages of production. This project will use intracranial recordings to characterise neuronal oscillations in combination with direct electrical stimulation, functional neuroimaging and non-invasive brain stimulation to establish critical areas and their timecourses with millisecond resolution. The outcome will be a better theoretical account of the brain mechanisms involved in spoken production. The benefit of this new theoretical account will be a better basis for prevention of post-surgical language impairment and neuromodulatory treatments after brain injury.Read moreRead less
When reading takes off: Children's word learning during independent reading. This project aims to address the major unsolved problem of how children build their knowledge about printed words through their reading. This is important since, once children have been taught the basics of reading, the primary means by which they learn new words is through reading experience. The project will use innovative technology to monitor children’s eye movements as they encounter new words during reading, exami ....When reading takes off: Children's word learning during independent reading. This project aims to address the major unsolved problem of how children build their knowledge about printed words through their reading. This is important since, once children have been taught the basics of reading, the primary means by which they learn new words is through reading experience. The project will use innovative technology to monitor children’s eye movements as they encounter new words during reading, examining factors influencing real-time cognitive processing and ongoing learning. Expected outcomes will be new insights into how to optimise children’s word learning when reading, and the refinement of a new computational model. These will inform policy and practice in reading instruction, to the benefit of Australia's children.Read moreRead less
A more sound approach to the neurobiology of language. How does the brain attain spoken language? Current neurobiological models assume either implicitly or explicitly that there is no relationship between a word's sound and its meaning. Yet considerable evidence shows this strong assumption about the arbitrariness of language is invalid. This project will use a combination of behavioural, neuroimaging and computational studies to characterise how the brain processes statistical regularities in ....A more sound approach to the neurobiology of language. How does the brain attain spoken language? Current neurobiological models assume either implicitly or explicitly that there is no relationship between a word's sound and its meaning. Yet considerable evidence shows this strong assumption about the arbitrariness of language is invalid. This project will use a combination of behavioural, neuroimaging and computational studies to characterise how the brain processes statistical regularities in sound-to-meaning correspondences as probabilistic cues to attain spoken language. The outcome will be a better neural account of language comprehension and production. The benefit of this new account will be a stronger basis for assessment and treatment of developmental and acquired language impairments.Read moreRead less
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. 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 ....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. 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
Lexical access in Australian languages. This project aims to investigate how listeners use cues from the way speech sounds are produced to break the speech stream into individual, recognisable words. The project investigates Australian languages which show unusual patterns in the production of speech sounds to generate new knowledge about speech perception and production. Outcomes will include advances in theories of speech processing, informing the development of speech processing systems, and ....Lexical access in Australian languages.

The dynamic world around us means we need to constantly adjust our decisions in light of ever-changing influences, both external (weather, traffic ...) and internal (fatigue, learning ...). This project aims to understand how these changes affect performance. This will have significance for basic science, and also practical benefits for applied psychology. This project will examine the dynamic nature of psychological processes in a range of settings: simple decisions, consumer decisions, human-machine interactions, and team performance. Theory development will lead to improved understanding of underlying cognitive processes, and transforms the measurement of decisions, which is important for applied psychological investigations.

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.

Beyond Speech: Towards better communication for children with hearing loss. Despite the benefits of early newborn hearing screening and early intervention programs for children with hearing loss, most still experience academic and social challenges at school. This is partly due to ongoing listening effort, leading to communicative breakdown. This project aims to identify the locus of the communicative challenges these children face during daily discourse interactions. The outcomes will identify ....Beyond Speech: Towards better communication for children with hearing loss. Despite the benefits of early newborn hearing screening and early intervention programs for children with hearing loss, most still experience academic and social challenges at school. This is partly due to ongoing listening effort, leading to communicative breakdown. This project aims to identify the locus of the communicative challenges these children face during daily discourse interactions. The outcomes will identify which levels of language are most compromised and will inform future interventions to reduce children’s listening effort. This will be undertaken by bringing together researchers in basic science with hearing service providers, parents and industry, providing an innovative model for solving multidisciplinary challenges.Read moreRead less
