From Wikipedia, the free encyclopedia
Feature-integration theory coined by Anne Treisman posits that attention is serially directed to different features of objects in order to distinguish them as meaningful wholes [1]. This multi-stage theory proposes that single features (colour, edges, motion, shape, etc) of objects are first perceived in the visual field through parallel processing. Following this, these single features are combined into meaningful objects through serial processing. In order for features to correctly combine into a unitary whole, focused attention must be present. With the absence of focused attention at this stage, perception of objects could lead to illusory conjunctions. However, if objects are not confounded by illusory conjunctions and are instead perceived by top-down processing (with the use of prior knowledge and experience), faster parallel processing could also take place with little use of focused attention.
