Approaching near-ideal strength for bulk amorphous metals. This project aims to develop a novel metal materials design strategy to break the strength ceilings of nanocrystalline metals and bulk metallic glasses. This strategy is based on a novel concept of synergy between a bulk amorphous matrix and phase-transforming nanocrystallites embedded within. The nanocrystallites, via their uniform transformation lattice distortion, prevent the formation of shear bands in the amorphous matrix and enable ....Approaching near-ideal strength for bulk amorphous metals. This project aims to develop a novel metal materials design strategy to break the strength ceilings of nanocrystalline metals and bulk metallic glasses. This strategy is based on a novel concept of synergy between a bulk amorphous matrix and phase-transforming nanocrystallites embedded within. The nanocrystallites, via their uniform transformation lattice distortion, prevent the formation of shear bands in the amorphous matrix and enable collective atomic load transfer to allow the amorphous matrix to continue to load to achieve its intrinsic near-ideal strength. The amorphous matrix eliminates the grain boundary plasticity of the nanoscrystallites. This concept is novel and untested in the history of physical metallurgy.Read moreRead less

A comprehensive intervention based on these insights aims to determine how scaffolding productive engagement can improve the quality of primary teachers' preparation for inquiry-based science.Read moreRead less
Rethinking higher education persistence. This project aims to address the issue of early departure from university. Many students leave higher education and disproportionate numbers are from educationally disadvantaged groups, including first-in-family learners. Too often, the individual learner is 'blamed' for this departure and perceived as deficit in necessary knowledge. This project extends previous research into how first-in-family students manage and engage with higher education. Expected ....Rethinking higher education persistence. This project aims to address the issue of early departure from university. Many students leave higher education and disproportionate numbers are from educationally disadvantaged groups, including first-in-family learners. Too often, the individual learner is 'blamed' for this departure and perceived as deficit in necessary knowledge. This project extends previous research into how first-in-family students manage and engage with higher education. Expected outcomes include knowledge about university persistence behaviours and a capabilities informed framework to design and implement future retention strategies.Read moreRead less
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. Th ....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. 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

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
