Working Memory and Attention during Simultaneous Language Interpreting: An EEG Study
Cognitive Sciences and Technologies: From Neuron to Cognition
The first chapter of the thesis offers a review of neuroimaging studies of simultaneous language interpreting (SLI) with a particular focus on the role of working memory (WM) and attention. It makes the case for a study of WM and attention during SLI in an ecologically valid setting using the event-related potentials (ERP) technique. In the second chapter we describe such an experiment to study neural activity associated with different levels of WM load during SLI. We pioneered the use of the ERP technique on conference interpreters articulating overtly. The amplitude of the N1 component elicited by task-irrelevant tone probes was significantly modulated as a function of WM load but not the direction of interpretation. The N1 amplitude decreased with load suggesting shallower processing under high WM load regardless of the direction.
