Differentiate between feature integration theory and guided search
What will be an ideal response?
Answer: Both feature integration theory (FIT) and guided search divide the perceptual system into separate feature maps. The feature information stored in these maps is location specific. According to feature integration theory, disjunctive searches isolate feature information in the appropriate feature map while conjunctive searches combine features from multiple maps for a particular location. The main difference between FIT and guided search is that guided search occurs in two stages. In the first stage, preattentive information is obtained and is used to rule out objects that cannot be targets. This information is then used to guide later serial searches.
