Event-Related Potentials

Event-Related Potentials (ERP) is a technique in cognitive neuroscience that allows the measurement of brain activity as it unfolds on a millisecond-by-millisecond basis. Brain measures are in turn linked to different cognitive functions.  The method’s high temporal resolution makes it a powerful tool for examining the human mind and brain; and particularly, for answering questions regarding the timing of different cognitive processes and the cascade of mental operations that take place in the stream of processing. As part of our work, we used the ERP technique to examine the effects of speaking more than one language (bilingualism) or dialect (bidialectalism) on non-verbal cognitive processing; specifically, on executive functions, a set of attention- and memory-related processes that regulate cognition and behavior in line with internal goals and current context. In recent research, we have also critically reviewed studies that examined the bilingual effect on executive functions with the ERP method; specifically, we provide an overview of the theoretical issues, methods, and results from this literature and discuss methodological recommendations for future research in order to advance the neurocognitive study of executive functions and bilingualism through the ERP lens.
