My research is concerned with the processes of semantic cognition – i.e., the ways in which we (a) maintain a store of conceptual knowledge about objects, words and people and (b) use executive control processes to access this information in a flexible, task-appropriate manner. I explore this using a variety of techniques, including:
- Case-series neuropsychological investigations, primarily of patients with semantic dementia and semantic deficits following stroke
- Computational linguistic analyses (e.g., latent semantic analysis)
- Repetitive transcranial magnetic stimulation in healthy subjects
- Functional neuroimaging studies
- Connectionist computational models
