Figure 4. The figure depicts cartoons of the target present trial stimuli for Experiment 1 (panels A and B) and Experiment 2 (panels C and D).

In panels A and B the target is a right-tilted bar (45 degrees from vertical) amongst left-tilted bars (−45 degrees from vertical). The target coincides with the irrelevant large feature in panel A; a nontarget coincides with the irrelevant large feature in panel B. In panels C and D the target is a vertical bar amongst bars tilted 30 degrees to the left and right of vertical. The target coincides with the irrelevant large feature in panel C; a nontarget coincides with the irrelevant large feature in panel D.
