She is Professor of Psychology at Pompeu Fabra University where she heads the Speech Acquisition and Perception (SAP) Research Group.
[6] Sebastián Gallés completed her PhD in Experimental Psychology at the University of Barcelona in 1986, where her work focused on morphological analysis and structure of the lexicon (dissertation title: Análisis morfológico y estructura del lexicón).
[10] Sebastián Gallés was coordinator of the Consolider-Ingenio 2010 research consortium from 2007 to 2012, which used cognitive neuroscience methods to study bilingualism.
With her colleagues in the SAP Research Group,[12] Sebastián Gallés has used electrophysiology to study brain activity associated with speech perception and language processing in participants ranging from young infants to adults.
[16] Later studies indicated that the bilingual advantage extended to infants' ability to visually discriminate unfamiliar languages to which they had no previous exposure.
