Prosem Lecture: Stimulating Speech: Auditory-motor Interactions in Production and Perception
March 22, 2021 @ 12:00 pm - 1:00 pm
Presenter: Ding-lan Tang, Ph.D., Postdoctoral Fellow, Department of Communication Sciences and Disorders, University of Wisconsin-Madison
Topic: Stimulating Speech: Auditory-motor Interactions in Production and Perception
Speech perception and production are two central aspects of human language. It remains unclear, however, how sensory and motor systems interact with each other during these two processes. In this presentation, I will discuss how transcranial magnetic stimulation (TMS) has been used to investigate the causal contribution of articulatory representation (in the left primary motor cortex) in speech adaptation. I will also discuss how TMS has been used in combination with brain-imaging techniques (i.e. Electroencephalography, EEG) to study asymmetry of auditory-motor speech processing in tonal and non-tonal language speakers. Overall, the work from these studies emphasizes the importance of understanding the interactions between auditory and motor systems when investigating speech perception and production. It also calls for mo re comparative studies between speakers of different languages, since ignoring the diversity of spoken languages can to lead to an incomplete understanding of the neurobiology of speech and language.
