PSY 3051 Lecture Notes - Lecture 6: Feature Integration Theory, Anne Treisman, Visual Search
Document Summary
Finding a target in a time series o o o. Feature search: also called parallel search o o. Looking for a combination of features: hard. When you look at an object, you recognize it"s color and orientation. That"s not how your brain processes the information. Visual display coded by two types of maps. Maps combine to pull attention to specific object. Simple features are detected because they activate unique parts of a feature map. Feature present is easier to detect than feature absent o. Simple features are bound to a location by the operation of focused attention. Without attention, features may be incorrectly bound to locations o. Patients have brain damage to both sides of the parietal lobe. Very poor at conjunction because attention shift is needed: neurophysiological evidence. Different features are coded by different brain regions. Failure to detect repetitions of visual stimuli in lists by rsvp.
