Abstract

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.
