Memory span refers to the maximum number of items (such as digits, words, or letters) a person can recall correctly in the exact order after a single presentation. This measure is a key component of short-term memory capacity, often assessed in psychological and cognitive research.
Memory span directly measures the number of items an individual can hold and accurately recall in short-term memory.
For most adults, the typical memory span is 5 to 9 items, often referred to as "Miller's Magic Number."
Information Booster:
Memory Span: Typically tested using tasks like digit span tests (forward or backward).
Chunking: Improves memory span by grouping related items (e.g., grouping digits in a phone number).
Phonological Loop: A component of working memory involved in the temporary storage of verbal material.
Miller's Law: George Miller proposed the memory span range of 7 ± 2 items, explaining the limitations of short-term memory.
Factors affecting memory span include age, cognitive ability, and distractions during testing.
