Testing the Modularity of Memory. Researchers disagree about whether verbal and visual working memory (WM) storage occurs in separate modules. Recent evidence suggests that only verbal memoranda have access to a specialised module, while visual memories make use of more general resources.

Researchers disagree about whether verbal and visual working memory (WM) storage occurs in separate modules. Recent evidence suggests that only verbal memoranda have access to a specialised module, while visual memories make use of more general resources. This project aims to re-examine interference between verbal and visual memoranda using statistical methods specialised for assessing whether multiple latent factors underlie performance on recognition memory tasks, examining adult and child populations. This is expected to influence applications of WM theory in many everyday settings, resulting in improvements in educational practices, workplace procedures, and clinical treatments that depend on theoretical understandings of limits in cognition.Read moreRead less
Tracking reading comprehension: What experts reveal about the mind. This project plans to use expert readers to provide a window on what defines optimal reading. Reading is a complex skill that requires precise coordination of cognition, perception and attention. By measuring skilled readers’ eye movements while they read sentences and short passages, the experiments are designed to investigate how individual differences in reading, spelling and vocabulary influence the timing and coordination o ....Tracking reading comprehension: What experts reveal about the mind. This project plans to use expert readers to provide a window on what defines optimal reading. Reading is a complex skill that requires precise coordination of cognition, perception and attention. By measuring skilled readers’ eye movements while they read sentences and short passages, the experiments are designed to investigate how individual differences in reading, spelling and vocabulary influence the timing and coordination of word identification and comprehension processes during normal reading and how this changes with a readers' goals. The results would distinguish between competing theories of how skilled readers balance word identification and comprehension processes, an issue that is critical to current debates about how reading should be taught.Read moreRead less
Cracking the code for skilled reading: the role of lexical quality in word and sentence reading. This project tests the hypothesis that highly skilled reading depends on precisely specified stored knowledge about written words. This project will investigate how individual diffences in reading, spelling and vocabulary among expert readers influence the time course of early orthographic and semantic processes in word identification and the pattern of lecical and contextual influences on eye moveme ....Cracking the code for skilled reading: the role of lexical quality in word and sentence reading.

Tracking towards a complete model of skilled reading comprehension. This project aims to promote the development of the first complete computational model of reading comprehension. Many computational models of sub-components of reading have been developed, but none fully explain the complex co-ordination of perceptual, attentional and cognitive processes required for successful comprehension. The project intends to use eye tracking studies to test and refine Über-Reader, a new computational mode ....Tracking towards a complete model of skilled reading comprehension. This project aims to promote the development of the first complete computational model of reading comprehension. Many computational models of sub-components of reading have been developed, but none fully explain the complex co-ordination of perceptual, attentional and cognitive processes required for successful comprehension. The project intends to use eye tracking studies to test and refine Über-Reader, a new computational model that aims to provide a complete account of the memory systems and cognitive processes involved in reading comprehension and how they differ with reading skill. The outcomes will advance understanding of the causes of success and failure in reading and contribute to diagnosing and remediating reading difficulties.Read moreRead less
Comprehending text: A natural laboratory for investigating cognitive ageing. This project aims to determine whether the cognitive processes required for reading comprehension change in old age. Reading is a complex skill that requires precise co-ordination of perception, cognition and attention but appears relatively immune to age-related declines that impair performance in other complex cognitive tasks. Sophisticated eye tracking and electrophysiological studies will be analysed to specify how ....Comprehending text: A natural laboratory for investigating cognitive ageing. This project aims to determine whether the cognitive processes required for reading comprehension change in old age. Reading is a complex skill that requires precise co-ordination of perception, cognition and attention but appears relatively immune to age-related declines that impair performance in other complex cognitive tasks. Sophisticated eye tracking and electrophysiological studies will be analysed to specify how older adults adapt to the sensory and neural impairments associated with age. The outcomes will advance theories of cognitive ageing and reading comprehension and contribute to development of novel interventions to predict and enrich cognitive capacities in old age.Read moreRead less

Cortical layer specific functional imaging of the human brain. This project aims to record layer specific cortical activity in humans by leveraging ultra-high field magnetic resonance imaging. It expects to yield robust techniques for the general analysis of neuroimaging-based, layer-specific measurements. This project will progress the fields of cognitive neuroscience and neuroimaging as well as bring the field of neuroimaging closer to that of neurophysiology and thus facilitate collaboration ....Cortical layer specific functional imaging of the human brain.

Learning from our mistakes: How and when complex decisions fail. The project aims to develop a novel mathematical framework, augmented by simulations and a set of experiments, to study when and how people commit errors. The modern environment bombards us with signals, such as radio and television advertisements as we sit at home or warning lights and car honks as we cross the road. Despite years of psychological research, it is not entirely clear how efficiently people cope with increasing amoun ....Learning from our mistakes: How and when complex decisions fail. The project aims to develop a novel mathematical framework, augmented by simulations and a set of experiments, to study when and how people commit errors. The modern environment bombards us with signals, such as radio and television advertisements as we sit at home or warning lights and car honks as we cross the road. Despite years of psychological research, it is not entirely clear how efficiently people cope with increasing amounts of information nor is it clear whether they process multiple signals simultaneously (in parallel) or one after the other (serial). The project offers new measures, based on the rate and pattern of error responses, to supplement the commonly used response times. The combination of a theoretical framework, based on mathematical and computational work, with empirical data to test the models, may deliver a better understanding of human performance and its limitations.Read moreRead less
Decoding the neural representation of objects in the human brain. Humans can effortlessly recognise thousands of objects in a fraction of a second. This essential capacity is an integral part of our daily lives that allows us to recognise our keys, our car, our friends and family. This project will elucidate how humans recognise objects by investigating the neural representation of objects in the brain.

Summary
The impact of expertise on visual processing: assessment of a new model. How is it that trained visual experts see things that elude most of us when looking at the same stimulus? This project proposes and tests a new theoretical framework for understanding how experience changes perception, with implications for optimising visual training programs that can contribute to public health and safety.
Choice models for learning and memory. Life is filled with familiar choices that often require quick decisions about objects in the environment and the contents of memory. This project examines how we learn to make rapid and accurate choices and how we quickly asses the level of confidence we have in recognition decisions based on our memories.
