The Science Behind the Game:
What is Working Memory?
"Working memory is a kind of short-term memory - it is a small amount of easily accessible information that our brains use specifically to accomplish cognitive tasks. Working memory is a critical part of how our brains work – we would not be able to do very much without it. Unlike long-term memory, working memory is ephemeral; it has a limited capacity and it doesn't last very long. Brain activity related to working memory takes place primarily in the pre-frontal cortex, although other areas in the brain are also involved. Measures of working memory tend to correlate with intellectual aptitudes, and are associated with cognitive development. Working memory's capacity tends to decline with age."

Wikipedia
"Working memory is the system that actively holds multiple pieces of transitory information in the mind, where they can be manipulated. Working memory is generally used synonymously with short term memory, but this depends on how the two forms of memory are defined. Working memory includes subsystems that store and manipulate visual images or verbal information, as well as a central executive that coordinates the subsystems. It includes visual representation of the possible moves, and awareness of the flow of information into and out of memory, all stored for a limited amount of time."
