Task-irrelevant stimulus salience affects visual search
The relative contributions of stimulus salience and task-related goals in guiding attention remain an issue of debate. Several studies have demonstrated that top-down factors play an important role, as they often override capture by salient irrelevant objects. However, Yantis and Egeth [Yantis, S., & Egeth, H. E. (1999). On the distinction between visual salience and stimulus-driven attentional...
متن کاملIrrelevant objects of expertise compete with faces during visual search.
Prior work suggests that nonface objects of expertise can interfere with the perception of faces when the two categories are alternately presented, suggesting competition for shared perceptual resources. Here, we ask whether task-irrelevant distractors from a category of expertise compete when faces are presented in a standard visual search task. Participants searched for a target (face or sofa...
متن کاملTask-irrelevant angry faces capture attention in visual search while modulated by resources.
We investigated the attentional capture effect of emotional faces under sufficient or restricted attentional conditions. In a modified visual search paradigm, three kinds of schematic faces (angry, happy, and neutral) served as stimuli. Participants were instructed to search for a target face indicated by a dot and to respond to the dot's position. In this design, the emotional content of the f...
متن کاملA Salient and Task-Irrelevant Collinear Structure Hurts Visual Search
Salient distractors draw our attention spontaneously, even when we intentionally want to ignore them. When this occurs, the real targets close to or overlapping with the distractors benefit from attention capture and thus are detected and discriminated more quickly. However, a puzzling opposite effect was observed in a search display with a column of vertical collinear bars presented as a task-...
متن کاملVisual short-term memory load modulates the early attention and perception of task-irrelevant emotional faces
The ability to focus on task-relevant information, while suppressing distraction, is critical for human cognition and behavior. Using a delayed-match-to-sample (DMS) task, we investigated the effects of emotional face distractors (positive, negative, and neutral faces) on early and late phases of visual short-term memory (VSTM) maintenance intervals, using low and high VSTM loads. Behavioral re...
