Visuospatial working memory mediates inhibitory and facilitatory guidance in preview search

Visual search is faster and more accurate when a subset of distractors is presented before the display containing the target. This “preview benefit” has been attributed to separate inhibitory and facilitatory guidance mechanisms during search. In the preview task the temporal cues thought to elicit...
