Fig 1. Visual stimulus.

Picture set for the sentence: Die nasse Ente tadelt der treue Hund. In English: The wet duck (accusative, but indicated ambiguously by the article “die”, nominative would also be possible) reprimands the loyal dog (nominative, indicated by the unambiguous article “der”). The target is depicted on the left side and competitor on the right side in this example. The three black circles are the fixation points for the EOG calibration, which disappear when the picture set is displayed. ROI 1 and ROI 2 are the regions of interest where the pictures are displayed. ROI 3 is the background. The figure is adapted from Wendt et al. [5] in a modified version.
