Document Summary
Change blindness: experiments show that experience allow for subjects to detect change faster. When it comes to semantic changes, experts were able to identify changes much faster than their novice counterparts. Ex: moving dots (zig zag, see saw, or both?: principle of rigidity, we assume that objects are rigid and that all points on a moving object move in synchrony. Motion capture: when the apparent motion of the perceptual illusion (illusory square in this instance) is capturing the movement of the surrounding dots/stimuli: principles of continuity. We assume that our environment is continuous, when it"s not continuous, however, this leads to change blindness: principles of simple causal explanations. Leads to synchronous motion (the array of dots, we assume that they move either up and down together or left to right together: principles of object permanence. How does the brain construct perceptual reality: 4 key ideas, the computational problem of perception is underspecified.
