![]() ![]() The prefrontal cortex is located in the frontal lobe of the brain. Research indicates that the main area of the brain associated with the working memory is the prefrontal cortex. The knowledge has what is called a "limited capacity", so there is only a certain amount of information that can be stored and it is easily accessible for only a small window of time after it has been processed, with a recall time block of roughly fifteen seconds to one minute.Įxperiments dealing with memory span have been conducted by George Miller in 1956 that indicated, "Most common number of items that can be stored in the working memory is five plus or minus two.” However, if this information is not retained and stored (“consolidated”) in one's long-term memory, it will fade quickly. The paramount feature that distinguishes the working memory from both the long-term and sensory memory is this system's ability to simultaneously process and store information. ![]() According to the formal definition, working memory is "a system for temporarily storing and managing the information required to carry out complex cognitive tasks such as learning, reasoning, and comprehension". Human memory can be divided into three broad categories: long-term memory, sensory memory, and short-term (working) memory. Some teachers and researchers have proposed that the eye–hand span can be trained to be larger than it would otherwise be under normal conditions, leading to more robust sight-reading ability. The relationship between load and latency changes according to tempo, such that t = x/y, where t is the change in tempo, x is the change in load, and y is the change in latency. Storage of notational information in working memory can be expressed in terms of the amount of information (load) and the time for which it must be held before being played (latency). An experiment on sight reading using an eye tracker indicates that highly skilled musicians tend to look ahead further in the music, storing and processing the notes until they are played this is referred to as the eye–hand span. The ability to sight-read partly depends on a strong short-term musical memory. Both activities require the musician to play or sing the notated rhythms and pitches. Sight-singing is used to describe a singer who is sight-reading. ![]()
