Description

Visual attention research has primarily focused on two sets of factors: bottom-up and top-down factors, whereby data-driven stimulus salience and observer goals and expectations respectively affect how we pay attention. However, recent research has prompted discussion of a third factor known as selection history, whereby one‘s previous experience with a stimulus affects attentional allocation. Here, we discuss how repeated exposure to a particular color facilitates attention allocation in the visual domain, demonstrating an RT advantage for valid trials compared to invalid trials. More interestingly, we find that the N2pc, an index of feature-based attentionallocation selection, occurs earlier in time for valid trials compared to invalid trials, suggesting an advantage for previously experienced colors. This work helps build upon an existing literature of selection history in influencing attention.
