PSY 3051 Lecture Notes - Lecture 5: Feature Integration Theory, Anne Treisman, Visual Search
Document Summary
Visual search: finding a target in space. Feature integration theory: finding a target in a time series. Looking for an odd man out: conjunction search. Feature integration theory: a visual display is coded by two types of maps. Master map of locations: master map of locations, feature maps. Contain info about the presence of a feature anywhere in the field; activity tells us what is out there. Have no info about where it is located and what other features the object has: master map of location. Has no info about which features are located where. Maps & attention: feature maps and location maps are insufficient, need some way of . Binding appropriate features together: attention does this Attention moves within the location map and selects whatever features are linked to that location (or that object). Evidence for the feature integration theory: feature vs. conjunction search. Feature search does not require attention efficient. Evidence for the feature integration theory: search asymmetry.
