Shannon L. Barrios

I am an Associate Professor in the Department of Linguistics at the University of Utah and co-director the Speech Acquisition Lab.

Prior to coming to the U, I was a graduate student in the Cognitive Neuroscience of Language Lab in the Department of Linguistics at the University of Maryland where I worked with Bill Idsardi and Naomi Feldman. I participated in the University of Maryland's interdisciplinary graduate training program title "Biological and Computational Foundations of Language Diversity," which is supported by the National Science Foundation's Integrative Graduate Education and Research Traineeship (IGERT) program.

RESEARCH

My research examines the role of existing phonological knowledge in the representation and processing of nonnative input. It combines insight from phonological theory, psycholinguistics and neurolinguistics in order to better understand the nature and persistence of cross-language influence in speech perception, spoken word recognition, and the acquisition of an L2 sound system.
