What is visual attention?
Visual attention is the process in which the human brain decides which details within the human field of vision are important and should be focused and which are largely ignored and filtered in the background. Information, such as low light -level environment, often increases the brain in detail to ensure that the required information is processed efficiently. If the basic information was not filtered according to the attention of the brain areas, one would be amazed by just a lot of visual information that picks up the eyes. Various models of how information is processed in the brain have been created, but none is proven. Visual attention is important in the daily life of people, because without the ability to filter information, tasks such as driving. By notifying the brain's attention to the desired details such as speed limits, potentially dangerous situations can be prevented because the brain emphasizes important details.
processing information to ensure that visual attention is paid to important details, they can take the form of behavior and active brain activities. The details needed to ensure that the person successfully completes the behavior or specific task is transmitted by the retina of the eye to the brain, and the information is not needed to complete less attention than the required details. The brain can also actively direct visual attention to specific details observed in everyday life, throughout the day, each person decides which information is required to achieve their goals and maintain its safety and health from the information observed.
The exact moment when the details are processed by the brain Airlevant information is filtered from what is seen have been described in many psychological theories. In some research studios, the claims for filtering information that take place directly after observation before the BUDou details fully processed brain. Other theories argue that the process of attention to detail is completed after all information in the field of view is processed by the brain, leading to a selection that is important or irrelevant at this point.
Determination that requires visual attention is important in situations where light levels are low and it is difficult to see people. Entering the dark environment after being in a clear environment, it requires that the brain of a person raise the darkened details into higher contrast to allow the person to find important information. Research on visual attention involves an attempt to better understand how the eyes and the brain interact.
