Memory Span Test

The digit span task measures your working memory capacity — the amount of information you can hold and manipulate in short-term memory. It is used in psychological assessments including IQ testing.

  • Average adult digit span: 6–7 digits forward, 4–5 backward
  • Forward span tests simple short-term memory retention
  • Backward span requires mental manipulation and tests working memory more deeply
  • Span can improve with practice and mnemonic techniques (chunking)
