Event overview
Departmental seminar series
Abstract: This talk will focus on the neural mechanisms by which human listeners achieve their remarkable success at perceiving and understanding speech. In line with Bayesian perceptual inference, perception of degraded speech is guided by prior knowledge. I will report multivariate analysis of fMRI and MEG responses to degraded words preceded by informative or uninformative written text. These studies show interactions between sensory detail and prior knowledge that are unlike the additive effects seen in perception, or expected for sharpening and direct coding theories (Aitchison & Lengyel, 2017). These findings therefore challenge traditional interactive activation accounts of speech perception, but are in line with predictive coding views in which evoked neural activity represents sensory prediction errors.
Bio: Dr Davis has been a Programme Leader at the MRC Cognition and Brain Sciences Unit at the University of Cambridge since 2012. Before coming to Cambridge for postdoctoral work, Matt studied Experimental Psychology at Oxford and gained a PhD from Birkbeck College, University of London.
This talk is part of the Departmental Seminar Series at the Department of Psychology at Goldsmiths, University of London. All are welcome to attend, no tickets are required, and any queries can be directed to Dr Daniel Yon (d.yon@gold.ac.uk).
