Document Summary

Cognition refers to thinking, acquiring and managing knowledge. Language is intimately related to the activities of cognition. It is a system of arbitrary symbols that can be combined to create an infinite number of meaningful statements. Cognitive psychologists study how people think and acquire knowledge know what they know, and how they solve problems and imagine. Attention is the tendency to respond to selectively to stimuli. It is general true that a feature or object that is unusual or different will get your attention quickly, while one that is surrounded by similar objects will require a long and patient search. Preattentive process : finding an unusual feature or figure relies on a preattentive process, a procedure for extracting information automatically. Attention process: finding a typical feature or figure requires an attentive process, a procedure that considers only one part of the visual field at a time.
