Figure 1.
A schematic of the trial sequence for both experimental conditions.
In the blocked condition the symbolic cue display was irrelevant to the task, whereas in the mixed condition each cue symbol signaled the type of saccade to be executed in the upcoming trial.

Error rate (%) and correct latency (ms) in each condition for both groups (means ± SD).
Figure 2.
Error rate (%) and correct latency (ms) under different conditions.
Panel (a). The mean direction error rate for prosaccades and antisaccades for younger and older participants. Panel (b). The mean correct latency for prosaccade and antisaccade tasks in the blocked condition and the mixed condition. Panel (c). The mean correct latency for near and far targets for younger and older participants. Error bars denote 1 standard error from the mean.
