Race Guides Attention in Visual Search.
It is known that faces are rapidly and even unconsciously categorized into social groups (black vs. white, male vs. female). Here, I test whether preferences for specific social groups guide attention, using a visual search paradigm. In Experiment 1 participants searched displays of neutral faces for an angry or frightened target face. Black target faces were detected more efficiently than whit...
متن کاملTask-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 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 کاملLearning to suppress task-irrelevant visual stimuli with attention
While the importance of attention in perceptual learning is widely recognized, the mechanisms through which it affects learning are poorly understood. Here we show that attentional mechanisms themselves are modified during learning. Attentional suppression of task-irrelevant stimuli becomes more efficient with practice. Attentional learning was found to be stimulus-specific and to persist for s...
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-...
