Can templates-for-rejection suppress real-world affective objects in visual search?

Area of Science:

• Cognitive Psychology
• Visual Perception
• Working Memory

Background:

• Feature-based templates in working memory can suppress environmental stimuli.
• Previous research used abstract shapes, limiting generalizability to real-world images and emotional stimuli.

Purpose of the Study:

• To investigate if feature-based rejection templates generalize to real-world images, including aversive stimuli.
• To examine the effectiveness of distractor inhibition in visual search tasks with real-world objects.

Main Methods:

• Participants performed visual search tasks with real-world objects after receiving distractor, target, or no-template cues.
• Experiments varied cue presentation, encoding time, and task demands (e.g., effortful comparison).
• A Bayesian meta-analysis synthesized results across experiments.

Main Results:

• Moderate evidence for increased capture by aversive distractors when distractor templates were randomized.
• Moderate evidence for effective distractor inhibition (aversive and neutral) when distractor templates were consistently cued with more encoding time.
• Weaker inhibition evidence in slower, effortful tasks, but modest inhibition for aversive distractors.
• Bayesian meta-analysis showed strong evidence for aversive distractor inhibition but inconsistent results for neutral distractors.

Conclusions:

• Feature-based rejection templates are effective for inhibiting real-world aversive distractors in visual search.
• Inhibition effectiveness depends on cue informativeness, accessibility, and the disruption caused by distractors.
• Rational search behavior framework explains the strategic use of cues based on potential benefits and costs.
