Experiment 4. Reaction times as a function of display size. Top: Target 5 created with cardinal line set; bottom: Target 5 created with diagonal line set. Dotted lines and triangles: 50% eligibility; solid lines and circles: 100% eligibility. The white symbols are absent trials, the black symbols are present trials. Next to each data point, the proportion error is given. On the side of the graphs is the search slope. The error bars represent standard error of the mean. Where there appear to be no error bars, they are covered by the data point
