I have taught undergraduates and postgraduates in the following areas:
Child Language Acquisition
Introduction to the Neurocognition of Language
Linguistics Frameworks (for Speech & Language Pathology)
- the speech, language and communication (SLC) performance of monolinguals and multilinguals,
- the effect of brain disease, brain injury or atypical development on SLC performance,
- the light that SLC breakdown can shed on healthy cognitive and neural processes, and
- whether changes in SLC can help in early detection of diseases affecting the brain.
To answer such questions I studied both healthy and atypical populations, using a range of methods including behavioural experiments, neuropsychological tests and fMRI brain imaging techniques. My doctoral research focused on characterizing SLC impairments in schizophrenia and how cognitive decline influences performance. This work led to collaborations examining the effects of IQ on neural function, and how previously reported neural abnormalities might be the result of cognitive decline rather than disease.
- What can SLC impairments can tell us about language in the healthy brain?
- Are there SLC changes specific to different brain diseases (including those affecting mental health) which can help us detect these diseases earlier?
My interest in performance extends beyond language function too. Previous and current collaborations include projects examining: (1) the striatal and hippocampal systems underlying non-language tasks in the ageing brain, and (2) the effects of mental vs. physical exercise on cognition, and how these different kinds of exercise augment performance.
