TL;DR: Evidence is found for anticipatory (proactive) suppression of frequent distractor locations in visual search already starting prior to display onset, and there was enhanced power in parieto-occipital alpha oscillations contralateral to the frequent distraction location—a signal known to occur in anticipation of irrelevant information.

TL;DR: It is found that short-latency first saccades are more likely to land on a region of the image with high salience than long-latencies and subsequent saccade targeting in both the encoding and visual search tasks, implying that salience indeed influences oculomotor behavior in natural scenes, albeit on a different timescale than previously reported.

TL;DR: A gaze-contingent eye-tracking paradigm revealed a crucial role for cognitive control in multiple-target search, consistent with models of visual selection in which only one attentional template actively drives selection and in which the efficiency of switching targets depends on the type of cognitive control allowed by the environment.

TL;DR: Results are consistent with the operation of different modes of control in multiple-target search, with switch costs emerging whenever reactive control is required and being reduced or absent when displays allow for proactive control.

TL;DR: The results revealed only small neural and behavioral costs associated with preparing for selecting two objects, but substantial costs when engaging in selection, and suggest this cost is the consequence of neural competition resulting in limited parallel processing, rather than a serial bottleneck.
