Our visual system is inundated with distracting objects that vie for our attention. While visual attention selects relevant information, inhibitory mechanisms might be useful to suppress the locations occupied by irrelevant distractors. Yet, there is a dearth of behavioral evidence for the active suppression of a distractor's location (ASDL) using central cues that provide preliminary information about a distractor's location. In the first two experiments, we attempt to conceptually replicate, using an online platform, experiments that provide evidence of the ASDL. We replicate the distractor cueing effect in a localization task (Experiment 1) wherein responses to targets were faster when a central arrow cued the location of an impending distractor than an empty location. This effect was larger in the first block of trials than it was in the second. In a discrimination task (Experiment 2), unlike previous studies, we found no evidence for an effect of distractor cueing. In Experiment 3, we replaced the central arrow cues with central number cues because arrow cues may elicit a symbolic shift of attention that might offset the ASDL. Once again, the best model was one in which the distractor cueing effect was absent. We replicate these failures to find evidence of the ASDL in two more experiments. The results suggest that the ASDL can be elusive and may be tied to the response system, not attention.

Working memory updating is an important executive process. Here, we study the single-neuron mechanisms involved in updating versus protecting memory from distractors in the macaque prefrontal cortex. We recorded single-neuron activity from the lateral prefrontal cortex (LPFC) and prearcuate cortex (PAC) while male monkeys performed a task that required them to update their memory of target locations while ignoring distractors.

In two experiments, we explored whether cross-modal cues can be used to improve foraging for multiple targets in a novel human foraging paradigm. Foraging arrays consisted of a 6 × 6 grid containing outline circles with a small dot on the circumference. Each dot rotated from a random starting location in steps of 30°, either clockwise or counterclockwise, around the circumference.

The brain's ability to prioritize behaviorally relevant sensory inputs (i.e., targets) while ignoring irrelevant distractors is crucial for efficient information processing.

Older adults struggle with tasks requiring selective attention amidst distractions. Experimental observations about age-related decline have relied on visual search designs using static displays. However, natural environments often embed dynamic structures that afford proactive anticipation of task-relevant information.

When we are presented with a coin rotated in depth, although we perceive its objective circular shape, the original perspectival shape is nonetheless represented in the visual system. Here we investigated the onset time and duration of such perspectival representation by systematically manipulating stimuli presentation time vs. post-stimuli retention time.
