short-term memory
Noun: * Short-term memory refers to the brain's system for temporarily holding and processing a limited amount of information. It is the capacity to retain a small number of items (like words, numbers, or images) for a brief period, typically a few seconds to a minute, without rehearsal. It is crucial for immediate tasks like understanding a sentence or dialing a phone number you've just been told.
Short-term memory is a cognitive function used to describe the immediate, conscious retention of information. * It is often contrasted with long-term memory, which stores information for extended periods. * The term is commonly used in psychology, neuroscience, education, and everyday conversation about mental performance.
