The phonological loop is one of three components of Baddeley's Working Memory Model. It is disproportionately engaged by language and verbal material. Digit span is a standard subtest in clinical batteries like the WAIS-IV.
What does the Number Memory test measure?
Number Memory (digit span) tests your working memory capacity - specifically the phonological loop, which rehearses and temporarily stores verbal information. George Miller's 1956 paper established that most adults can hold 7±2 items, known as "The Magical Number Seven." The sequence gets one digit longer after every successful recall.
How to improve your Number Memory score
- → Chunk digits into groups of 3 (like a phone number). "149276" becomes "149" + "276."
- → Sub-vocalize (mentally whisper) the sequence to engage the phonological rehearsal loop.
- → Consistent daily practice of 10 minutes can increase your span by 1–2 digits within weeks.
- → Take the test in silence - background speech especially disrupts phonological working memory.
