Developing a Unified Theory of Episodic Memory. This project aims to develop a model of episodic memory and to apply the model to both adult and child development data. Unlike current approaches, the model is expected to address multiple memory tasks including item recognition, associative recognition, source recognition and cued recall, and also aims to address reaction time data, allowing different sources of interference causing forgetting in adults to be identified. By addressing both encodi ....Developing a Unified Theory of Episodic Memory. This project aims to develop a model of episodic memory and to apply the model to both adult and child development data. Unlike current approaches, the model is expected to address multiple memory tasks including item recognition, associative recognition, source recognition and cued recall, and also aims to address reaction time data, allowing different sources of interference causing forgetting in adults to be identified. By addressing both encoding and retrieval processes, the model can assess how changes in different sources of interference modulate performance through the trajectory of early development. Hierarchical Bayesian estimation aims to enable a simultaneous account of multiple tasks and support future deployment in applied contexts.Read moreRead less
The Psychology of Misinformation—Towards A Theory-driven Understanding. 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 ....The Psychology of Misinformation—Towards A Theory-driven Understanding. 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

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.
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. 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 ta ....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. 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
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.

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
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.

Language is what makes us distinctly human; consequently, language attracts interest from many fields of research, particularly linguistics, psychology, and cognitive science. Moreover, language is the primary medium for the storage and dissemination of knowledge, a fact that has drawn many computer scientists to attempt to process, analyse and understand language. This network will bridge the many disciplines that are concerned with language, explore new ways in which computational models inform our understanding of human languages, and exploit new opportunities for applying theories of language in the development of human language technologies.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.

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

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
