Fig. 1: Task illustration.

Schematic illustration showing the timing and the stimuli sequence and of the experimental paradigm. The cue is represented by an arrow pointing either left or right, while the consecutively shown stimuli S1 and S2 both constitute a bar that can differ by color (red or green), position (top or bottom), and orientation (vertical or horizontal). The first response is given following S1 and is based on the direction of the cue, while the second response is given following S2 and is based on the orientation of S2.
