Improving the diagnosticity of eyewitness memory choices. Eyewitness identification error is common and costly. This project aims to improve the quality of information provided by eyewitnesses, and the ability of police officers and triers of fact (e.g., juries, judges) to evaluate this information. Laboratory investigations will determine how best to test memory and confidence to achieve this aim. A new class of cognitive models will provide a unified account of response accuracy, response time ....Improving the diagnosticity of eyewitness memory choices. Eyewitness identification error is common and costly. This project aims to improve the quality of information provided by eyewitnesses, and the ability of police officers and triers of fact (e.g., juries, judges) to evaluate this information. Laboratory investigations will determine how best to test memory and confidence to achieve this aim. A new class of cognitive models will provide a unified account of response accuracy, response time, and confidence, suitable for application to computerized testing scenarios. The models and testing methods validated in the laboratory will be refined for application in eyewitness memory settings, facilitating better evaluation of identification evidence, and potentially reducing wrongful convictions.Read moreRead less
Nurturing Australia's Little Multilingual Minds. Despite its substantial multilingual capacity of more than 300 languages, Australia has been described as a 'graveyard for languages'. In partnering with community organisations we will facilitate polyglot early learning, commencing with Spanish and Vietnamese. Expected outcomes are a deep understanding of multilingual families’ experiences, a model to support lifespan multilingual education, and openly-accessible database of child language in her ....Nurturing Australia's Little Multilingual Minds. Despite its substantial multilingual capacity of more than 300 languages, Australia has been described as a 'graveyard for languages'. In partnering with community organisations we will facilitate polyglot early learning, commencing with Spanish and Vietnamese. Expected outcomes are a deep understanding of multilingual families’ experiences, a model to support lifespan multilingual education, and openly-accessible database of child language in heritage languages. Benefits include a pivotal contribution to early childhood education with the creation of a tailor-made, principle-based program, which will enhance children’s academic achievement, familial social and mental wellbeing, and cultural and economic opportunities for all Australians.

Are super-complex words represented like sentences in speakers' minds? This project aims to examine speakers' knowledge of super-complex words in the remote Australian language Wubuy. The project will provide a crucial test of current theories of language processing and linguistic typology via experimental work on the Indigenous language Wubuy, a language that defies the perceived fundamental distinction between words and phrases. This will have significant benefit to Indigenous language mainten ....Are super-complex words represented like sentences in speakers' minds? This project aims to examine speakers' knowledge of super-complex words in the remote Australian language Wubuy. The project will provide a crucial test of current theories of language processing and linguistic typology via experimental work on the Indigenous language Wubuy, a language that defies the perceived fundamental distinction between words and phrases. This will have significant benefit to Indigenous language maintenance and revitalisation efforts and thus help improve Indigenous education outcomes and reinforce cultural pride.Read moreRead less
Human Scheduling of Perceptual Tasks. This project aims to develop a novel approach for synthesising how people prioritise information with theories of attention and decision making. Characterising inefficient scheduling in the tradeoff between the difficulty and the cost/benefit of different subtasks will allow the development of a formal computional model that generalises statistical models of rank order data to a theory of the timing of scheduling decisions and task completions. Outcomes incl ....Human Scheduling of Perceptual Tasks. This project aims to develop a novel approach for synthesising how people prioritise information with theories of attention and decision making. Characterising inefficient scheduling in the tradeoff between the difficulty and the cost/benefit of different subtasks will allow the development of a formal computional model that generalises statistical models of rank order data to a theory of the timing of scheduling decisions and task completions. Outcomes include benchmark data from a novel paradigm for studying perceptual decisions and behavior and a model which can explain and predict human scheduling. This project aims to benefit industry by allowing for the simulation of information prioritisation by human agents in complex environments.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.

Summary
Context matters: from sensory processing to decision making. Contextual modulation refers to prominent changes in the processing of information in brain and perception caused by interactions across space and time. Over the past two decades, an enormous amount of work has shown that spatial contextual effects occur throughout the sensory processing hierarchy. However, there has been little work examining how temporal context effects affect information processing and operate for high-level attribu ....Context matters: from sensory processing to decision making. Contextual modulation refers to prominent changes in the processing of information in brain and perception caused by interactions across space and time. Over the past two decades, an enormous amount of work has shown that spatial contextual effects occur throughout the sensory processing hierarchy. However, there has been little work examining how temporal context effects affect information processing and operate for high-level attributes of stimuli as well as interactions of self and environment. The project aims to fill this gap to further understand the nature and mechanisms of temporal contextual modulation on sensory information processing, perception, perceptual judgement and decision making at cellular, circuit and cognitive levels.Read moreRead less
Creating perceptual experts in Australia's policing and security agencies. This project aims to create the next generation of experts in Australia’s policing and national security agencies, by improving crime scene evidence interpretation. Agencies are under pressure to develop more rigorous training practices that go beyond mere intuition and tradition. This project will use a novel approach that directs learning toward the most diagnostic perceptual cues. Expected outcomes include a solid empi ....Creating perceptual experts in Australia's policing and security agencies. This project aims to create the next generation of experts in Australia’s policing and national security agencies, by improving crime scene evidence interpretation. Agencies are under pressure to develop more rigorous training practices that go beyond mere intuition and tradition. This project will use a novel approach that directs learning toward the most diagnostic perceptual cues. Expected outcomes include a solid empirical basis for national training programs designed to create experts that are accurate, reliable, and continuously improving. Improving the training of experts will ensure the integrity of forensics as evidentiary tools available to police, lead to more reliable courtroom convictions and help safeguard Australia from terrorism and crime.Read moreRead less
