Using generalisation to better treat poor spelling. Spelling is an important skill when expressing one's thoughts in writing and an acute challenge for at least ten per cent of Australian students, who can be years behind in their knowledge. This project will help to improve spelling training by establishing how to facilitate generalisation of spelling knowledge from a learned word to new words.
How do people make uncertain predictions? Exemplar-based and category-based approaches to inductive inference. This project is an innovative experimental and field study of how people reason under uncertainty. The project will broaden our understanding of human reasoning and enhance the reputation of Australian cognitive science.
Dynamics of word recognition: new insight from the reach-to-touch paradigm. This project will introduce a new behavioural reach-to-touch paradigm for studying basic cognitive processes such as word recognition. The advantage of this paradigm is that it is able to measure cognitive processes moment-by-moment as they unfold over time. This will provide new insights into the temporal dynamics of basic cognitive processing.
Higher cognition and hemispheric specialization in an avian species: referential and intentional communication. We will discover whether alarm calls of Australian magpies, noted for their outstanding range of vocalisations, are referential (signalling predator type and location) and intentional (vocalised in specific contexts). Such complex communication , once thought to be unique to humans, has been found in some mammals and just one avian species, the domestic chick. This project will be the ....Higher cognition and hemispheric specialization in an avian species: referential and intentional communication. We will discover whether alarm calls of Australian magpies, noted for their outstanding range of vocalisations, are referential (signalling predator type and location) and intentional (vocalised in specific contexts). Such complex communication , once thought to be unique to humans, has been found in some mammals and just one avian species, the domestic chick. This project will be the first such investigation of an avian species in its natural habitat. This is important also because bird and mammalian brains are organised differently and birds offer a unique opportunity to discover whether one hemisphere is specialised for this purpose.Read moreRead less
Risky Futures: Toward a Computational Process Model of Risky Inter-Temporal Choice. A lot is known about people’s preferences. People like their rewards now. Most would prefer $10 today than $20 in one month. Risk is also unattractive; a certain $10 is more attractive than a 50 per cent chance of receiving $25. Surprisingly, much less is known about the interaction between delay and risk. That is, relatively little is known about whether people prefer $10 now, or a 50 per cent chance of $50 in ....Risky Futures: Toward a Computational Process Model of Risky Inter-Temporal Choice. A lot is known about people’s preferences. People like their rewards now. Most would prefer $10 today than $20 in one month. Risk is also unattractive; a certain $10 is more attractive than a 50 per cent chance of receiving $25. Surprisingly, much less is known about the interaction between delay and risk. That is, relatively little is known about whether people prefer $10 now, or a 50 per cent chance of $50 in one month. This project will use a combination of experiments and cognitive modelling to examine all three types of choice. The outcome will be a novel computational model that will elucidate the complex interaction between delay and risk, thereby answering an enduring question in the literature: are risk and delay psychologically equivalent?Read moreRead less
Poor social functioning in schizophrenia: understanding its causes and developing better treatments. This project will advance knowledge of the thinking processes and the associated neural changes that cause the lifelong social disability which characterises schizophrenia. Findings will, in turn, contribute to better identifying young people, at risk of developing schizophrenia, and inform the design of new interventions and treatments.
Moral reasoning and mental illness: towards a model of moral judgment and moral accountability. This research examines capacities for moral judgment in people with schizophrenia, some of whom act on their delusional beliefs and commit crimes. Findings will, in turn, inform legal and philosophical consideration of the moral accountability of mentally ill defendants, and advance theoretical knowledge of healthy moral decision making.
Adapting cognition to a changing climate. Research indicates that public knowledge of the causes and consequences of global warming are poor, and a correct understanding is a key predictor of behaviour that reduces carbon footprints. This project applies basic principles of cognitive science to improve public knowledge and thereby increase the likelihood of reducing carbon footprints.
Cracking the orthographic code: investigating early perceptual processes in reading. Current understanding of how human readers decode a string of letters into known words is inadequate. This project advances understanding of this early reading process, by combining computational modelling, behavioural and brain imaging approaches.
Unifying decisions from experience and description. The project aims to answer an enduring question: are separate theories required for decisions from experience and description? For some decisions, potential outcomes and probabilities are known – a gamble offering a 10 per cent chance to win $100 or a 90 per cent chance of nothing, for example. For many others, there is no ‘look-up table’ of probabilities and outcomes and so we must learn them via experience. Intriguingly, risky choices made on ....Unifying decisions from experience and description. The project aims to answer an enduring question: are separate theories required for decisions from experience and description? For some decisions, potential outcomes and probabilities are known – a gamble offering a 10 per cent chance to win $100 or a 90 per cent chance of nothing, for example. For many others, there is no ‘look-up table’ of probabilities and outcomes and so we must learn them via experience. Intriguingly, risky choices made on the basis of described or experienced information differ markedly. This project examines why this divergence occurs. The project plans to test an innovative approach that unifies both types of decisions into a single theoretical framework and provides a suite of empirical and modelling results.Read moreRead less
