Sensorimotor control in speech production

The lab uses real-time manipulations of auditory, somatosensory, and visual feedback during movement to examine sensorimotor control, predictive processing, and forward model acquisition in speech and co-speech hand movements. Key work in this area includes:

The brain basis of speech processing

In addition to the behavioural work above, the lab is also interested in the brain basis of speech—in particular, the role of cortical motor areas and the cerebellum in speech processing. We tackle this problem using large-scale meta-analyses of the neuroimaging literature or by combining behavioural manipulations with neural measures like fMRI and noninvasive brain stimulation.
