Working memory, also known as short-term memory, is a component of the human memory system that stores a limited amount of information for a short period of time. It is responsible for holding information that is actively being used in a specific task or problem-solving process. Working memory is essential for many cognitive processes, such as comprehension, reasoning, and decision-making. It is closely related to attention and can be divided into different subsystems, such as auditory and visual working memory. Working memory has a limited capacity, and information that is not transferred to long-term memory is lost after a short period of time.
