“…As a starting point, our explorative analysis of the dominant and minor target locations revealed that almost as many second-presented as first-presented target locations became the dominant target location. Pollmann and Zheng (2023) showed that a larger contextual cueing effect develops for targets on the right vs. the left half of the display. They argue that, due to an initial leftward bias, participants already respond quickly to targets in the left half of the display, so that there is not as much opportunity to improve as with targets in the right half of the display.…”

Humans find visual targets more quickly when the target appears at the same location in a repeated configuration of other stimuli. However, when the target alternates between two locations in the repeated configuration, the benefit for visual search is smaller. This reduction of benefits has been explained as the result of an averaging of a benefit for one location and a cost for the other location. In two experiments, we investigated this two-target-locations effect in real-world scenes using high-resolution eye-tracking. Experiment 1 adapted a study in which subjects searched for a small “T” or “L” superimposed on real-world photographs. Half of the trials showed repeated scenes with one possible target location each; half showed novel scenes. We replicated the pronounced contextual cueing effect in real-world scenes. In Experiment 2, two conditions were added. In one of them, targets appeared in repeated scenes alternating between two possible locations per scene. In the other condition, targets appeared in repeated scenes but at new locations, constrained to one side of the screen. Subjects were faster to search for and identify a target in repeated scenes than in novel scenes, including when the scene was paired with two alternating target locations and (after extensive training) even when the scene only predicted the hemifield. Separate analyses on the two possible target locations resulted in rejection of the suggestion of costs for the additional target location, since the contextual cueing effect was present in the second half of the experiment for both the favored and the less favored target location. The eye-tracking data demonstrated that contextual cueing influences searching fixations, characteristic of attentional guidance, rather than responding fixations, characteristic of facilitation of response processes. Further, these data revealed that adding another possible target location leads to less guidance, rather than impeding response processes. Thus, this study delivers evidence for a flexible and attentional guidance mechanism that is able to prioritize more than one location in natural contexts.
