A computational and experimental investigation of reading aloud: Dyslexia, disyllables, and beyond. Australia is a world leader in computational cognitive science, particularly with respect to language processing. This project will help maintain and extend this position.

Australia is a world leader in computational cognitive science, particularly with respect to language processing. This project will help maintain and extend this position. Insights from the project will help us understand the processes that underlie both normal reading and reading disorders, particularly in areas that are comparatively neglected yet extremely important, such as how people read words of more than one syllable. Given that everyone in Australian needs to learn to read and that acquired and developmental disorders of reading are common, providing the theoretical base on which the processes involved in reading can be understood (and hence learnt and remediated most effectively) is of utmost importance.Read moreRead less
Cognitive science: simulating the interactive evolution of human communication systems. We do not know how language first arose (the event left no trace), but it can be studied by simulating the circumstances under which new languages arise today. By having people play a game where they create new communication systems from scratch, this project will illuminate the origin of human language.
Cultural Dynamics of Narratives: Micro and Macro Implications of Narrative Transmission. Stories circulated in everyday conversations may have global implications by exerting a subtle cultural influence on social actions. Stories about martyrdom and wartime heroics, for instance, describe what goals a protagonist pursues in what way in what context. We propose that in communicating such stories people affirm and re-affirm for each other what they should do under what circumstances. The exchange ....Cultural Dynamics of Narratives: Micro and Macro Implications of Narrative Transmission. Stories circulated in everyday conversations may have global implications by exerting a subtle cultural influence on social actions. Stories about martyrdom and wartime heroics, for instance, describe what goals a protagonist pursues in what way in what context. We propose that in communicating such stories people affirm and re-affirm for each other what they should do under what circumstances. The exchange of these stories can result in the formation and transformation of a large-scale cultural grouping, which may have significant socio-political implications such as extremist terrorism and intercultural clashes. We test these propositions in experiments and computer simulations.Read moreRead less
The Formation and Maintenance of Stereotypes through Communication. Stereotypes are culturally shared beliefs about social groups. Although many stereotypes may be formed on the basis of hearsay, and often maintained through our everyday conversations, little is known about how they are formed, maintained, and transformed through interpersonal communications. This project examines this question with a view to developing a social psychological theory of how culturally shared beliefs may be formed ....The Formation and Maintenance of Stereotypes through Communication. Stereotypes are culturally shared beliefs about social groups. Although many stereotypes may be formed on the basis of hearsay, and often maintained through our everyday conversations, little is known about how they are formed, maintained, and transformed through interpersonal communications. This project examines this question with a view to developing a social psychological theory of how culturally shared beliefs may be formed, maintained, and transformed, especially when they can have undesirable consequences such as prejudice and discrimination.Read moreRead less
Information seeking, cognition, and individual differences. The public now has access to vast amounts of scientific knowledge and information on the internet and in other new media. Paradoxically, this increasing availability of knowledge has been accompanied by the increasing traction of pseudoscientific misinformation. This project explores the reasons underlying those trends and seeks solutions.
Attention vs Perception: When is selection optimal, when relational? This project aims to investigate an important, newly discovered dissociation between early visual selection and perceptual decision-making. Contrary to current theories, attentional and perceptual processes are tuned to different stimulus attributes described in the relational vs. optimal account, which implies that current theories of attention do not describe early attention but later, decisional processes. This project will ....Attention vs Perception: When is selection optimal, when relational? This project aims to investigate an important, newly discovered dissociation between early visual selection and perceptual decision-making. Contrary to current theories, attentional and perceptual processes are tuned to different stimulus attributes described in the relational vs. optimal account, which implies that current theories of attention do not describe early attention but later, decisional processes. This project will provide an accurate description of these processes, which promises important theoretical breakthroughs. Work on this project will also significantly advance methods to detect and describe early attentional processes, by identifying error-prone methods of Psychophysics and Neuroscience studies, and proposing remedies.Read moreRead less
Explaining the native-language listening advantage by charting neural response and perceptual adaptation across languages – but within individuals. Listening to the native language is easier than listening to a second language. This advantage is especially clear in recognising voices and in listening in noise. Identifying talkers was recently shown to involve rapid perceptual adjustment to their speech sounds, and successful listening in noise to involve adjustment of word recognition processes. ....Explaining the native-language listening advantage by charting neural response and perceptual adaptation across languages – but within individuals. Listening to the native language is easier than listening to a second language. This advantage is especially clear in recognising voices and in listening in noise. Identifying talkers was recently shown to involve rapid perceptual adjustment to their speech sounds, and successful listening in noise to involve adjustment of word recognition processes. This project tests the prediction that listeners more efficiently deploy each type of adjustment in the native than in a second language, by comparing native with second language phonetic and lexical processing within individuals. Further, a novel fMRI method in which target brain regions are defined functionally in each subject will identify the neural basis of the native listening advantage.Read moreRead less
Learning from others: Inductive reasoning based on human-generated data. Most of the data we see every day, from politics to gossip, comes from other people. Making inferences about such data is difficult because the people who provided it may have biases or limitations in their knowledge that we do not know about and must figure out. This project uses a series of experiments tied to normative computational models of social reasoning to explore how people solve this problem. This work has the po ....Learning from others: Inductive reasoning based on human-generated data. Most of the data we see every day, from politics to gossip, comes from other people. Making inferences about such data is difficult because the people who provided it may have biases or limitations in their knowledge that we do not know about and must figure out. This project uses a series of experiments tied to normative computational models of social reasoning to explore how people solve this problem. This work has the potential to make a major impact in understanding how information is understood and shared, especially when it is about topics that people lack firsthand knowledge about, like climate change. The computational models also have applications to the development of expert systems upon which our information economy relies.Read moreRead less
Cognition, culture, and textual encounters: a study of what cognitive science and the earliest English poetry can do for each other. This project examines, through multidisciplinary tools drawn from cognitive science, how we are able to understand texts written over 1000 years ago, through the cognitive structures and cultural factors that shape meaning. Using cognitive approaches to literature, this study demonstrates the complex interplay of mind, culture, and literary texts.
Beyond Segments: Towards a lexical model for tonal bilinguals. Most people in the world today speak more than one language. Thus, they need to decide, unconsciously, which language to use at any given time. This project aims to understand how healthy adult bilinguals resolve competition from their unintended language to communicate successfully in the intended language. In both bilingual language comprehension and production, the project will characterise the role of an under-explored linguistic ....Beyond Segments: Towards a lexical model for tonal bilinguals. Most people in the world today speak more than one language. Thus, they need to decide, unconsciously, which language to use at any given time. This project aims to understand how healthy adult bilinguals resolve competition from their unintended language to communicate successfully in the intended language. In both bilingual language comprehension and production, the project will characterise the role of an under-explored linguistic dimension, lexical tone, in cross-language processing. Expected outcomes include enhanced understanding of bilingual communication and theories of bilingual language use, and practical implications for optimal language learning for bilinguals and intervention for clinical populations who speaks two languages.
