Grand-averaged ERP amplitudes. Grand-averaged event-related brain potentials (N = 15 in both experiments) to different syllables in the pseudowords and the whole pseudowords averaged over the whole experiments. The ERPs are time-locked to syllable onsets at time 0. The grey area indicates the time window of significant differences between the responses. In both experiments, there is a significant difference between the responses to S1 (blue) and S3 (green).
