What is a visual search?
Visual search is an exercise including a visual brain center. It is designed to test the visual sharpness of man and the time of mental response. Visual search includes the location of a certain object, often in a field of similarly shaped and colorful objects. It is often used as a diagnostic or therapeutic tool in visual testing. It also creates the basis for popular games and books that are usually designed for children, but are played by people of all age groups.
The basic visual search is common human activity. Most people routinely perform such a dozens a day. Examples include the location of a particular product on the shop shelves, recognizing a friend's face in a group of foreigners, or finding clothes in a closet. In fact, what seems to be a simple process involves complex coordination of eyes with different parts of the brain. This allows people to distinguish items based on color, location and other factors.
Brain activity studies revealed which parts of the brainU are connected to various aspects of visual search. As a result, such searches can be a diagnostic tool for medical staff. If the patient has problems with simple visual search, it may be a sign of brain disorder, such as Alzheimer's disease, injury or lesion in the brain. Similar tests can detect problems with the eye's eye or the eye itself. The color blind test includes visual search that requires the patient to recognize the shape in a larger pattern only by color.
In visual search, the entity is obliged to find one object or group of objects called the target. The target is located in the middle of other objects called distractors. Increasing the number of distractors and their similarity to the target object makes visual search. Another factor in such searches is the reaction time: how long it takes to be subject to the target item. For this reason, some visual searches have a time limit or otherwise establish their outcomey for the time for which the task requires.
Visual search also consists of popular games, many designed for children and others for adults. Some include finding a picture masked as a background detail in the drawing. Another visual search game is the word search where players must find words hidden in a block of random letters. Where is the book Wally? Where's Wally? , known in the US and Canada as Where is Waldo? , in the 1990s became a cultural phenomenon and the series remains popular in the 21st century.
