What’s happening in the bilingual brain? A seminar on the use of electrophysiological methods in the study of bilingualism
In 1980, Kutas and Federmeier were one of the first researchers to use electroencephalography (EEG) in the study of language. They investigated event-related brain potentials (ERPs) elicited by the processing of semantically inappropriate words in the context of sentences (e.g. He spread the warm bread with socks). Consistently across participants, an increase in the amplitude of a negative wave peaking at 400 ms was found following the presentation of the semantically incongruent word. This became known as the N400, an ERP component linked to the processing of meaning. Since then, the use of electrophysiological methods in the study of language processing has flourished. The excellent temporal resolution of these methods allows language researchers to investigate processing as it unfolds, at the milliseconds (ms) level. On top of that, the superior granularity of these techniques enables the observation of phenomena that behavioral techniques cannot grasp. For instance, it is argued that behavioral measures may not be sensitive enough to identify some group differences, whereas the electroencephalogram (EEG) might be. In the field of bilingualism, early work by Genesee and colleagues (1978) used the EEG to investigate bilingual language processing. Focusing on a very prominent group difference, they reported that differences in age of exposure to a second language (L2) lead to different patterns of neurophysiological activity during a language recognition task. Also focusing on bilingualism, in the present seminar I will discuss three electrophysiological methods (ERPs, rsEEGs, and neural oscillations) and present the most relevant findings of a scoping review of recent studies that used these methods to investigate bilingual language processing.
