Figure 1.
The response times for visual search for a right-tilted target bar among left-tilted nontargets (see Figure 4 panels A and B) as a function of display size for the target absent, target-present nonsingleton, and target-present singleton conditions are plotted.
Error bars in this and all RT plots are 95% confidence intervals, calculated according to Loftus and Masson [20].

Histogram of the attentional capture effect for Experiment 1.
The number of participants as a function of the difference between the mean RT of the nonsingleton target trials (Nonsing) and the singleton target trials (Sing) for each subject.
Figure 3.
Experiment 2 results plotting response time as a function of display size for the target absent, target-present nonsingleton, and target-present singleton conditions.

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.
