Figure 1.
A typical trial sequence in Experiment 1.
Prior to each trial, participants maintained fixated on a centrally presented disk until a stable fixation was detected. Upon depression of the spacebar, a drift correction was applied and a trial was initiated with the presentation of a centrally presented fixation cross. Following 500 ms, the fixation cross was replaced by the search display, which was presented for 3000 ms. Following each block, feedback regarding the speed of participants' initial saccade was provided and participants were given the opportunity to take a short break.
Figure 2.
Salience-driven selection in initial saccades in Experiment 1.
Proportions of initial saccades directed towards each of the three singletons (22.5°, 45°and 67.5°), separately for each bin of the response time distribution and irrespective of target identity.
Figure 3.
Salience-driven selection in second saccades in Experiment 1.
Proportions of second saccades directed toward either of the two remaining singletons, separately for each bin of the response time distribution and irrespective of target identity, given that the initial saccade landed on A) the most, B) the medium, or C) the least salient singleton.
Figure 4.
Salience-driven selection in initial saccades in Experiment 2.
Proportions of initial saccades directed towards each of the three singletons (22.5°, 45°and 67.5°), separately for each bin of the response time distribution and irrespective of target identity.
Figure 5.
Salience-driven selection in second saccades in Experiment 2.
Proportions of second saccades directed toward either of the two remaining singletons, separately for each bin of the response time distribution and irrespective of target identity, given that the initial saccade landed on A) the most, B) the medium, or C) the least salient singleton.
Figure 6.
Goal-driven selection in Experiment 2.
Proportions of eye movements correctly directed toward the right-tilted target singleton, averaged over all salience conditions, separately for each bin of the response time distribution for A) initial and B) second saccades.
