Document Summary

Perception is affected by bottom-up and top-down processes. Perception operates at the front-end of human behavior the way you use an object depends on what you believe the object is: bottom-up processes. Our ability to perceive rests largely on the information in the stimulus itself or bottom-up/data drive processes. Bottom-up: refers to the fact that the observer takes small amounts of information from the environment and combines it to form a percept. Does not do a good job at capturing the flexibility in the human perception. Feature analysis: recognize objects by recognizing components parts or features and the manner in which they are combined. Selfridge"s pandemonium model: image demon encodes a stimulus and feature demons represent only one feature. When a feature demon sees something it recognizes, it screams. When the cognitive demons hear a feature demon screaming, they start screaming too. A decision demon listens to cognitive demons and chooses the cognitive demon that is screaming the loudest.
