Traditionally, the allocation of attention was understood within goal-driven and stimulus-driven factors. However, the traditional approach cannot fully account for the mechanism of attentional orienting. Instead, a growing body of evidence shows that previous search experiences, irrelevant to both goal-driven and stimulus-driven factors, influence attentional allocation. For example, when contexts predict information of targets, the contexts guide attention toward the stimuli having the information predicted by the contexts: contextual cueing. In addition, more valuable stimuli attract more attention: value-driven attentional capture. However, two critical issues are present. First, contextual cueing has been found largely when the contexts and the target …

Leveling The Viewing Field: The Impact Of Target Prevalence On Searcher's Functional Viewing Field, Juan D. Guevara Pinto

It is well known that target prevalence impacts various cognitive processes. In visual search, rare search targets are more difficult to detect than common targets. The present research investigated novel questions about target prevalence, focusing on observers’ functional viewing field (FVF) during passive search tasks. The FVF is the area in a display where attention is focused and item processing is enhanced. According the FVF framework (Hulleman & Olivers, 2017), the size of the FVF is modulated by the ease of target detections, such that visual search involving difficult target detection reduces the FVF. Although this would suggest that low …
