as depicted in Figure 4. The only difference between
Experiments 1 and 2 was that the box boundaries
were visible in Experiment 2. Thus, it appears likely that
the boxes rendered bounce events more predictable and
thereby eliminated the attraction of attention to bounce
events. We compared the effect of bounces of the nonqueried
target in the last 200 msec of the trial across Experiments
1 and 2. To do this, we compared errors in the
0–200 msec bounce category after normalizing them by
subtracting individuals’ mean errors in the no-bounce (in
the last 1,000 msec) baseline condition and then dividing
by each individual’s standard deviation of errors.
