Document Summary
Inattentional blindness: not paying attention to something clearly visible: ex. the gorilla in the passing the ball video. Change blindness: difficulty in detecting changes in scenes: ex. the asking for directions, change the person video. When cues are added, telling people something had changed, much quicker to detect the changes. Continuity errors errors in films, where something changes even though the scene was supposed to be continuous. Binding: process where features (colour, form, motion, location) are combined to create a coherent perception. Binding problem: question of how the individual features get bound together. Flashed different features onto a screen for 1/5 of a second. Subjects reported having seen objects made up of a combination of the different stimuli: illusory conjunctions: combining features from different stimuli. Demonstrates that we combine different features supports binding. Occurs b/c at the pre-attentive stage features exist independently of each other: they"re free floating. Can be incorrect combined to form a perception.
