What is the change of blindness?
Blindness is a receptive phenomenon where observers do not notice visual changes, sometimes very extreme, which shows that the brain does not always process scenes in accurate details, but rather gives a general overview. The famous and often repeated experiment that demonstrates the blindness of changes is the basketball scenario where observers are asked to watch a short clip of basketball games. The experimenter often provides a task such as counting passages or falls. Most observers do not notice that the person in the Gorilla suit enters the center of the court, gestures and then leaves again.
Despite the name, the change of blindness is not a visual impairment and is not a disorder. All people demonstrate it to some extent, although some seem less prone than others. For example, autism tends to reduce the amount of blindness the change that the observer is experiencing. Research on autism and visual processing suggests that autistic people are less capacity to be foreign details, so note when something in ith the environment changes.
visual images go through a number of forms of processing when they hit the brain so the observer can understand the image. The brain can assign a sense of direction, name objects in the scene and provide a context to help the observer interpret it. The change of blindness seems to be the result of the brain's desire to provide a quick overview of the scene in favor of the observer; For example, the brain could decide that a person looks at a crowded airport terminal or a forest scene based on general information, but would not provide specific details such as the exact location of each tree or the color of the luggage on the corner of the eye.
change blindness becomes even more extreme when visual distraction is present. On the example of the forest scene, if the deer boundary, the observer's view may not notice that the hunter has appeared. At a crowded airport terminal, the eye will be attracted towards moving zavaa rear wheelchair or aircraft and can miss a change on departures or arrival. They may also ask people to complete tasks to make a change in blindness because they focus on the task instead of what they see. Therefore, a more fauional leaflet that scans the album album for a joining flight does not have to notice that someone will enter their journey.
Scientists who study this phenomenon perform experiments, such as a random switching of a person with whom the object speaks or edits movies to put scenes or cause the characters to change their heads in the middle of the scene. In both examples, many observers will not notice changes, although it will prove to be notified and always find it easy to find in the future.
