To be really effective, for example, a simultaneous interpreter needs a repertoire of approaches.
“Language is one of the more complex human cognitive functions,” Narly Golestani, the group leader of [University of Genneva’s] Brain and Language Lab, tells me during a recent visit. “There’s been a lot of work on bilingualism. Interpretation goes one step beyond that because the two languages are active simultaneously. And not just in one modality, because you have perception and production at the same time. So the brain regions involved go to an extremely high level, beyond language.”
