Senior Lecturer in Cognitive Psychology
My research investigates interactions between intentional and automatic processes during long-term memory retrieval. I am particularly interested in the neurocognitive mechanisms that allow us to control what aspects of our past we consciously remember — both in terms of facilitating memories that we want to retrieve and also preventing unwanted memories from automatically coming to mind. I use a combination of behavioural and cognitive neuroscience techniques (EEG, MEG, fMRI, TMS) to address questions such as:
- What are the neurocognitive mechanisms that enable us to stop unwanted retrieval?
- Is memory-related brain activity under voluntary control, and if so, what are the implications for tests that use brain activity markers of memory as evidence of criminal guilt?
- Can retrieval attempts enhance learning of new information and updating of existing memories?
- What are the effects of healthy ageing on retrieval processes, retrieval-induced learning and memory updating?
