What is a visual short -term memory?

Visual short -term memory is an area of ​​memory that allows people to store visual information, usually for less than a minute, in case they need it for information. The memories stored in this way are subject to rapid disintegration and decay quickly because the brain determines that they are not necessary for long -term use. The processes involved in the coding and storage of memory are very different from short -term and long -term memories, and evocation processes are also clear.

In humans, the visual short -term memory tends to be limited in extent, with people in their short -term memory three to seven pieces of visual information. This allows people to do things like remembering facial expressions to register visual changes or remember the color for references during the test. If the memories are actively used, they move to the brain working memory to look at the brain, and otherwise break down and become unresolved.

Information stored in visual short -term memory isFor easy acnebyatable quick downloads, if necessary, but does not last. It may be a problem with situations such as interviews with criminal witnesses. People who see crime may think they are reliable sources of information, especially if it has just happened, but their memories can be defective; For example, a blue car can turn into a red car into a withdrawal or the physical properties of the perpetrator may not be precisely induced.

Short -term memory generally seems to rely on verbal than visual allusions. It is much easier for people to remember larger pieces of verbal information, such as a list of numbers than to watch visual information. Visual short -term memory can provide useful harsh references, but may also be surprisingly unnoticeable. For example, many people show a phenomenon known as blindness of change where they do not notice significant environmental changes until flip changes several times back and forth.

Research by visual short -term memory examines the ways people code this information and load this information, and what happens when it goes wrong. For example, people with brain injuries and degenerative neurological diseases may have difficulty in creating short -term memories. This can make it difficult for them to engage in everyday activities, although they have perfect long -term memories of the events that have occurred in the past. Understanding how and why the brain creates memories can help scientists develop new approaches to treating memory loss and related disorders.
