PSY 100 Lecture Notes - Lecture 7: Feature Integration Theory, Inattentional Blindness, Attentional Blink
Document Summary
The selection of a source of sensory stimulation for increased cognitive processing. Failure to notice a change between two scenes: If the change doesn"t alter the gist or meaning of the scene, quite large change can pass unnoticed. Demonstrates that we do not encode and remember as much. Inattentional blindness: of the world as we might think. The phenomenon of not being able to perceive things that are in plain sight. Caused by an absence of attention to the unseen object. An experimental procedure in which stimuli appear in a stream at one location at a rapid rate. Used to study the temporal dynamics of visual attention. The difficulty in perceiving and responding to the second of two target stimuli amid a rsvp stream of distracting stimuli. The second target is often missed if it appears within 200 ms. Attentional bottleneck: to 500 ms of the first target. We think we see much more than we actually do.
