Figure 1.

Single trial and average ERPs from electrode CPz from a single subject for unambiguous accusatives placed before a nominative. In the upper part, single trials are displayed stacked and sorted from top to bottom in decreasing orthographic length as a weak proxy for acoustic length, while the lower part displays the average ERP. Amplitude is given by color in the upper part and by the y-axis in the lower part. The dashed vertical lines indicate the boundaries of the N400 time window, 300 and 500 ms after stimulus onset.
