Working Memory
Also known as: Short-Term Memory, Mental Workspace
The cognitive system that temporarily holds and manipulates information for complex tasks like reasoning and learning.
FULL EXPLANATION
Working memory is the cognitive system responsible for temporarily holding information available for processing. Unlike simple short-term memory, working memory involves actively manipulating information, like doing mental arithmetic or following complex instructions.
Working memory capacity is limited (typically 4-7 items) and is closely linked to general intelligence and academic/professional success. It's primarily supported by the prefrontal cortex and is sensitive to stress, fatigue, and aging.
WHY IT MATTERS
Working memory underlies complex thinking, problem-solving, and learning. It's a key component of cognitive function that can be maintained and potentially improved.
HOW TO IMPROVE
Support working memory through adequate sleep, regular exercise, stress management, working memory training, and minimizing cognitive overload.
NORMAL RANGES
Working memory span is typically 4-7 items for most adults. It can be measured through digit span, n-back tasks, and other neuropsychological tests.
