the left side of the head. This was designated the easy condition. On the remaining target trials, the nose pointed to the bottom of the screen. In this hard condition, an ear on the right side of the screen corresponded to the left side of the head and vice versa. Correct responses on these trials entailed pressing a button with the hand opposite to the side of the screen the ear appeared on. There were an equal number of left and right ears in both the easy and the hard conditions. These target stimuli were presented pseudorandomly within a series of 160 neutral stimuli consisting of a simple oval. Participants were instructed not to respond to these nontargets. Stimuli appeared with a duration of 98 ms and an intertrial interval that varied randomly between 1 s and 2 s.
