Cognition

Cognition When the human eye sees a word or an object, it uses a network of detectors, organized in layers, going from the least complex to the most. The bottom layer, is concerned with features, and therefore is called a feature net. These detectors range in their need for strong or weak inputs in order to make them fire. Each detector has an activation level, a response threshold, and a baseline activation level. The activation level tells us how active a specific detector is at that moment. The response threshold tells us how high the activation level must get in order to warrant a response from the detector. The baseline activation level is the detectors activation level when the detector is not receiving any inputs. If a detector is used all the time, its baseline activation level will be higher, so it will require fewer inputs in order to fire. A feature net can be used to explain object recognition also. When a person sees an object, they immediately see the object as it’s component shape, or geons. This means, that before our minds even register what an object is, it organizes the object by shape, and then determines what the object, level, activation, recognize, feature, inputs, detector, very, order, nets, net, time, therefore, response, explain, detectors, baseline, word, threshold, tells, system, shape, sees, recognition, quickly, need, must, means, itself, help, first, few, features, allow, feature, wrong, without, whole, weak, warrant, until, understand, type, three-dimensional, think, strong, speedy, specific, sounds, sometimes
