Early processing of auditory lexical predictions revealed by ERPs
چکیده انگلیسی
Auditory lexical processing starts within 200 ms after onset of the critical stimulus. Here, we used electroencephalography (EEG) to investigate whether (1) the so-called N200 effect can be triggered by single-item lexical context, and (2) such effects are robust against temporal violations of the signal. We presented items in which lexical status (i.e., is the stimulus a word or a pseudoword?) was determined at third syllable onset. The critical syllable could be naturally timed or delayed (by ∼440 or ∼800 ms). Across all conditions, we observed an effect of lexicality that started ∼200 ms after third syllable onset (i.e., an N200 effect in naturally timed items and a similar effect superimposed on the P2 for the delayed items). The results indicate that early lexical processes are robust against violations of temporal coherence.
