PS262 Lecture Notes - Lecture 8: Illusory Motion, Extrastriate Cortex, Biological Neural Network
Document Summary
Motion helps us understand events in our environment. Motion perception is essential for our ability to move through the environment. As a person moves forward, objects move relative to the person in the opposite direction. this movement, called optic ow, provides info about the walker"s direction and speed. The ability of motion to attract attention is called attentional capture. this effect occurs not only when you are consciously looking for something but also while you are paying attention to something else. The fact that movement can attract attention plays an important role in animal survival. Our own motion relative to objects is constantly adding to the info we have about the objects, and we receive similar info when objects move relative to us. Observers perceive shapes more rapidly and accurately when an object is moving. Actual motion of an object is called real motion e. g. a car driving by, people walking, or a bug scurrying across a tabletop.
