Since ERPs responses were strongly modulate by the PoA of the syllables, we decided to treat bilabial, alveolar and velar syllables independently for further analysis, rather than collapsing them into the syllable condition. Bilabial syllables elicited greater amplitude in N270 compared with velar syllables (t= -3.993, p=0.0018 ETA) and in N400 compared with velar syllables (t= -4,804, p = 0.0001 ETA) and alveolar syllables (t= -3,174, p=0.0290 ETA). No significant differences were found for components P2 and P1000 (Fig.2).
