“…For instance, participants can learn that a certain location in a search display has a higher probability of containing targets (e.g., Addleman et al, 2018; Ferrante et al, 2018; Geng & Behrmann, 2002, 2005) or distractors (e.g., Goschy et al, 2014; Wang & Theeuwes, 2018; Won et al, 2019; Zhang et al, 2019), respectively, accelerating target detection or enhancing distractor suppression, which both result in more efficient search. It is generally assumed that VSL modulates the allocation of visual attention via dynamic weight adjustments within the spatial priority map (e.g., Anderson et al, 2021; Fecteau & Munoz, 2006; Itti & Koch, 2001; Zelinsky & Bisley, 2015), even though others have challenged this view (see Allenmark et al, 2019; Liesefeld & Müller, 2021; Sauter et al, 2018). Taking the study by Geng and Behrmann (2002) as an example, each spatial location is initially weighed equally due to the same physical saliency and features (i.e., similar letters).…”
