metadata.value: In this article, we consider the issue of categorical influences on visual search performance.
  In order to compare the mechanisms of such influences, described in modern paradigms, we
  use two parameters: the accessibility of categorical information and the form of its representation.
  The parameter of accessibility concerns the temporal aspect: on which stage of a search
  task the participants have access to the categorical information. This information could be
  available during a search task or before it during the target presentation stage. The second
  parameter is a form of representation of categorical information. It could be represented directly
  as categorical knowledge, or indirectly by an object’s visual features. Our analysis shows
  the following: If categorical information is available only at the target demonstration stage
  and represented indirectly by visual features, then it influences visual search by recalling a
  prototype of a target category, the visual features of which then form a search template. If a
  category of a scene is also available, then it helps to choose the most relevant zones in a scene
  for search. Additional information of distractors’ categories will draw participants’ attention
  to the objects which are categorically similar to a target. Finally, if categorical information is
  available directly during the search stage, it influences our attention more than visual features.
  Therefore, we conclude that the mechanism of categorical influences on visual search depends
  on the amount of categorical information available to a participant. The more categorical
  information of objects and a scene is available to participants, the more it influences visual
  search performance.
