Abstract
While classical literature identify in the N400 component the electromagnetic counterpart of lexical access and semantic integration processes, several studies showed earlier effects of semantics on the amplitude and latency of previous ERP responses, such as Lexical Processing Negativity (LPN), P140 or N170 components. In the present study, automatic lexical access processes were investigated in right-handed readers engaged in an orthographic detection task. EEG was recorded from 32 scalp sites in highly specialized native Italian simultaneous interpreters. They were all right-handed women with a mean age of 40 years. They were recruited according to their professional use of English (L2, active interpretation: ITo4EN) andGerman (L3, consecutive or passive interpretation: IT
