Figure 15. Distribution of mean differences between same-object and different-object trials, and 95% confidence intervals for each subject in Experiment 3.

The difference between the two object conditions is significant if the 95% confidence interval does not include the value of 0. Significant differences are denoted by filled circles; non-significant differences are shown with white circles. The circles on the right side of the figure denote a positive difference, which is the opposite direction predicted by theories of object-based attention.
