Abstract

The brain has been shown to honor the fundamental linguistic difference between semantic and syntactic information. Here we demonstrate that it even further indicates the necessity to distinguish between two differential syntactic processes: that is to say between the processing of phrase structure information necessary to build up syntactic structures on-line and verb argument structure information crucial to build up representations of who is doing what to whom. The former process is reflected in the event-related brain potentials (ERPs) as an anterior negativity followed by a late centro-parietal positivity, whereas the latter process is reflected as a centro-parietal negativity–positivity pattern. The different ERP patterns clearly suggest that the theoretically assumed difference between local syntactic structure building and argument structure processing is neurophysiologically real.
