Working Memory

Working memory (pronounced: /ˈwɜːrkɪŋ ˈmɛməri/) is a cognitive system with a limited capacity that can hold information temporarily. It is important for reasoning and the guidance of decision-making and behavior. Working memory is often used synonymously with short-term memory, but some theorists consider the two forms of memory distinct, noting that working memory allows for the manipulation of stored information, whereas short-term memory only refers to the short-term storage of information.

Etymology

The term "working memory" was first used in the 1960s in the context of theories that likened the mind to a computer. The term "working" was used to denote that this form of memory is used to manipulate information, similar to the way a computer's processor manipulates data.
