Answer to Question 1
Answer: Attention is not a single process or confined to one area of the brain. Instead, attention arises from the competition created from multiple sources of inputs. As a result, attention occurs across a variety of brain areas and inputs or information are selected via a variety of mechanisms (e.g., early selection, late selection, top-down, and bottom-up). Thus, attention arises from the integrated processing of competing pieces of information.
Answer to Question 2
Answer: Feature integration theory incorporates a number of feature maps that also contain information about the location at which a feature is present. When doing a disjunctive search for a red target, for example, the participant only needs the information from the color map. However, a conjunctive search for a red square, for instance, requires information from the color map and the shape map. Acquiring information from two maps takes more time than obtaining information from only one map. Therefore, conjunctive searches take more time than disjunctive searches.
