Attention please! Selective attention and human associative learning. Selective attention allows us to pick useful pieces of information out of the mass of stimulation that we're faced with every moment. This project investigates how what we've previously learnt about the significance of events influences whether we'll pick them out as useful in future, and how this might be impaired by old age or mental disorder.
A process model of visual working memory. This project aims to develop a process model of encoding of items into memory. Working memory is central to almost all cognitive functions, but little is known about short-term memory for visual information. Progress in this area is slow because of a focus on models that do not specify the processes underlying memory, and no model explains the processes that would limit the number of items the memory can hold to four. A process model is expected to addre ....A process model of visual working memory. This project aims to develop a process model of encoding of items into memory.

Progress in this area is slow because of a focus on models that do not specify the processes underlying memory, and no model explains the processes that would limit the number of items the memory can hold to four. A process model is expected to address fundamental issues in visual working memory.Read moreRead less

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.
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.

Uncovering the dynamics of object selection from movement trajectories. This project aims to establish the dynamic properties of selection for perception and action, and develop a computational model of object selection across perception and action. Everyday actions depend on isolating the relevant object (perceptual selection) and appropriate grasp (action selection). It was long thought that distinct and sequential stages of processing carried out perceptual and action selection, but recent fi ....Uncovering the dynamics of object selection from movement trajectories. This project aims to establish the dynamic properties of selection for perception and action, and develop a computational model of object selection across perception and action. Everyday actions depend on isolating the relevant object (perceptual selection) and appropriate grasp (action selection). It was long thought that distinct and sequential stages of processing carried out perceptual and action selection, but recent findings suggested that a single mechanism may subserve both. Through a two-pronged approach including rigorous empirical work and computational modelling, this project aims to study this fundamental aspect of human cognition.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
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.

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 movements during sentence reading.Read moreRead less
The Psychology of Misinformation—Towards A Theory-driven Understanding. The project aims to develop a psychological theory of misinformation effects.

The project aims to develop a psychological theory of misinformation effects. Misinformation influences people’s memory, reasoning and decision-making even after corrections – it thus poses a significant challenge for science and society. Through the combination of systematic experimentation with theory-driven computational modelling, the project will strive to concurrently consider individual-level cognition and the impact of sociocultural context. It is anticipated that this novel integrative approach will substantially expand our understanding of misinformation effects, and that this theoretical progress will result in the formulation of specific communication strategies to reduce the impact of misinformation on society.Read moreRead less

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

Summary
A model based approach to investigating short-term memory: exploiting response time distributions. Working memory is one of the most fundamental and well studied aspects of human cognition. The project plans to develop and test a computational modelling framework into which fundamental theories of short-term memory can be placed. This unique approach will offer a deeper understanding of the underlying components of working memory.
