What is the iconic memory function?
iconic memory is a sensory storage for vision. It works temporarily in memory of the vision of icons, which are images and forms, even after the image is no longer visible. This involuntary ability allows the retina to maintain the basic structure of the image even after leaving and no longer visible. This temporarily retained iconic image is maintained long enough for immediate purposes and then lost or moved to long -term or short -term storage. The cult memories that have been moved to long -term storage can be used to compare similar icons or pictures later. The iconic memory storage is used to keep the memories of images between flashing. Without it, the vision would consist of disconnected static images without records of the movement of retina. This sensory trade also allows the brain to process a sense of movement or movement in a continuous stream, as when a bird flies over the backyard from a tree to a fence.
Scientists say that the development of iconic memory functions begins at infant age and evolves, because the systems of visual perception in the stages create a strong connection between the information received by the eyes and brain centers of visual processing. Adult capacity for iconic memory is fully developed until the child is approximately five years old. However, the length of the image is held so that it corresponds to the time the adult holds memory at the age of eleven. Throughout life, human iconic memory capabilities can only reduce 20 milliseconds aged 20 to 60 years, thereby excluding any unforeseen brain damage with injury or illness.
Research by otic memory has found that the decrease in iconic memory can be associated with the early signs of Alzheimer's disease. The loss of some iconic memory was found in those who show dysfunction known as mild cognitive disorders (MCI), who most likely develop Alzheimer's disease.The ability to transfer information to short or long -term storage is equivalent to a much older population without a medical history of MCI. In studies, however, in patients with MCI, short -term memory length and iconic memory length are reduced.
