Uncovering the processes underlying human category learning. There is a pervasive belief that complex tasks can somehow be learned via a 'smart' implicit or procedural learning mechanism, which operates independently of memory and attention. This idea has important implications for our understanding of cognition. If true, there seems little point in providing explicit instruction in such tasks, and efforts to do so are, at best, wasted time and, at worst, detrimental to the learning process.

There is a pervasive belief that complex tasks can somehow be learned via a 'smart' implicit or procedural learning mechanism, which operates independently of memory and attention. This idea has important implications for our understanding of cognition. If true, there seems little point in providing explicit instruction in such tasks, and efforts to do so are, at best, wasted time and, at worst, detrimental to the learning process. This project will provide much-needed scrutiny of this idea and will help not only to re-orient our understanding of how we deal with complex information, but will also highlight issues about data interpretation that are fundamental for the research and wider communities.Read moreRead less
Binding in working memory. Cross-modal binding?the integration of verbal and spatial features of events?is central to human cognition. However, it has been neglected in the study of working memory, where the dominant theoretical framework includes separate subsystems for the retention of verbal and spatial information. Using novel paradigms involving the concurrent auditory presentation of verbal and spatial information, the proposed research is directed at discovering (1) the fundamental chara ....Binding in working memory. Cross-modal binding?the integration of verbal and spatial features of events?is central to human cognition. However, it has been neglected in the study of working memory, where the dominant theoretical framework includes separate subsystems for the retention of verbal and spatial information. Using novel paradigms involving the concurrent auditory presentation of verbal and spatial information, the proposed research is directed at discovering (1) the fundamental characteristics of binding, and (2) the extent to which benchmark effects previously identified with a particular modality are ?inherited? by the other modality under conditions conducive to binding. Outcomes of the research will provide important constraints on the development of theories of working memory. In addition, the research will develop paradigms that have potentially important applications to clinical psychology, where diverse forms of psychopathology have been linked to deficits in binding.Read moreRead less
The role of retrieval cues when remembering over the short term. This project has two principal benefits: A basic scientific outcome concerning the development of a cue-driven memory model and an applied outcome that can inform the design of language learning tools. A core assumption proposed to explain short-term memory performance is that an event's salience affects its memorability. To date however, this salience dimension has escaped experimental vigour. This project examines the conditions ....The role of retrieval cues when remembering over the short term. This project has two principal benefits: A basic scientific outcome concerning the development of a cue-driven memory model and an applied outcome that can inform the design of language learning tools. A core assumption proposed to explain short-term memory performance is that an event's salience affects its memorability. To date however, this salience dimension has escaped experimental vigour. This project examines the conditions under which some events are perceived to be more salient than others. In addition, by determining when, and which cues are more salient, the project can inform future design of language learning tools (e.g., interactive memory games). Read moreRead less
Memory And Time. What could be simpler than remembering a few items, such as the digits in a phone number, for a brief time in the right order? Notwithstanding its simplicity, this serial recall task is essential for sophisticated human abilities such as vocabulary acquisition. This project investigates whether chronological time is a causal variable in short-term memory, as some?but by no means all?theorists assume. Experiments will manipulate time between items at study and retrieval using nov ....Memory And Time. What could be simpler than remembering a few items, such as the digits in a phone number, for a brief time in the right order? Notwithstanding its simplicity, this serial recall task is essential for sophisticated human abilities such as vocabulary acquisition. This project investigates whether chronological time is a causal variable in short-term memory, as some?but by no means all?theorists assume. Experiments will manipulate time between items at study and retrieval using novel techniques, and thus observe the effect of time on memory. Computational models of psychological time will be developed to better predict memory performance.Read moreRead less
Categorization and Working Memory: Bridging two Pillars of Cognition. Categorization is a fundamental cognitive skill that underlies much expert behavior, including medical diagnosis. A given task often gives rise to widely divergent strategies across individuals, and flawed strategies have been implicated in prediction errors of experts (e.g., bush fire fighters). This project seeks to identify the underlying variables that determine an individual's strategy acquisition by relating working memo ....Categorization and Working Memory: Bridging two Pillars of Cognition. Categorization is a fundamental cognitive skill that underlies much expert behavior, including medical diagnosis. A given task often gives rise to widely divergent strategies across individuals, and flawed strategies have been implicated in prediction errors of experts (e.g., bush fire fighters). This project seeks to identify the underlying variables that determine an individual's strategy acquisition by relating working memory performance to categorization. Working memory is a core cognitive construct that is quite well understood, but its relationship to category learning has so far remained unexplored. Being able to predict the development of categorization strategies can help maximize expert performance.Read moreRead less
Are two processes one too many? An investigation of the viability of the dual-process model of recognition memory. Memory is the glue that holds together our lives and personal identities. While psychologists are developing better and more sophisticated accounts of how it works, many deep questions remain. The present research examines some of these questions in relation to how memory can be decomposed into its component processes and how we are to understand these processes. An appropriate unde ....Are two processes one too many? An investigation of the viability of the dual-process model of recognition memory. Memory is the glue that holds together our lives and personal identities. While psychologists are developing better and more sophisticated accounts of how it works, many deep questions remain. The present research examines some of these questions in relation to how memory can be decomposed into its component processes and how we are to understand these processes. An appropriate understanding of these questions is vital to the development of interventions (both psychological and pharmacological) designed to halt or even reverse memory decline associated with normal aging and age-associated brain disease (such as Alzheimer disease).Read moreRead less
Working Memory: The Binding of Spatial and Nonspatial Features in the Retention of Visual and Auditory Information. By advancing the understanding of how integrated representations are retained in memory for the features of visual objects and the features of sounds, the research will provide new theoretical insights as well as new methods for investigating several forms of psychopathology. Deficits in feature binding have been argued to be implicated in autism, in the auditory hallucinations exp ....Working Memory: The Binding of Spatial and Nonspatial Features in the Retention of Visual and Auditory Information. By advancing the understanding of how integrated representations are retained in memory for the features of visual objects and the features of sounds, the research will provide new theoretical insights as well as new methods for investigating several forms of psychopathology. Deficits in feature binding have been argued to be implicated in autism, in the auditory hallucinations experienced by individuals with schizophrenia, and in memory decline with advancing age. By investigating these deficits using insights from the proposed study, researchers may be able to develop ways to ameliorate the adverse effects of the deficits.Read moreRead less

This project has two principal benefits: A basic scientific outcome concerning the evolution of language and an applied outcome that can inform the design of graphical communication tools. The evolution of language is one of the most hotly debated issues in contemporary science, but to date it has escaped experimental examination. This project develops an experimental methodology that permits examination of the processes by which human knowledge evolves across generations of teachers and learners. In addition, by also examining the final content of evolution, and by determining what type of graphical symbols emerge out of communal evolution, the project can inform the future design of graphical communication tools (e.g., road signs).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.

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
