Digit Span (Digit Span): Targeted training of working memory

Digit Span (Digit Span) is a classic psychological test for measuring working memory capacity. You are shown a sequence of numbers which you must recall after a short pause. The sequences become longer until you make mistakes.

Forward vs. Backward

Forward: reproducing numbers in the same order — trains phonological memory, attention and auditory processing. Backward: numbers in reverse order — trains working memory, executive functions and mental flexibility. The backward span is typically 2 digits shorter.

Strategies for better results

Chunking: Instead of 4-7-2-8-3-1 remember 47-28-31. Visualization: picture the numbers. Assign meaning: 47 = house number, 28 = age. Rhythm and melody: say the numbers with a rhythm — music uses different memory systems.

Scientific Significance

Digit Span is a standard test for ADHD diagnosis, dementia screening, learning disorders and intelligence tests. Average forward span in adults: 7 (±2) digits, backward span: 5 (±2). With training most people can increase their span by 1-2 digits.
