How the task works
Hold each sequence briefly, then enter the digits in order. Difficulty increases with sequence length and results should be compared at the same presentation settings.
Digit Span
Hold a short number sequence in mind, then enter it from memory.
Choose sequence length
Each session contains five new sequences.
Task guide and research
Online digit span practice for immediate serial recall
Digit span presents a short number sequence and asks you to reproduce it in the same order. It is a classic simple-span format for immediate verbal short-term memory.
Research connection
Computerized digit-span research supports its use as a measure of short-term verbal memory under controlled administration. Visual presentation, self-administration, and scoring choices can produce different results from clinical tests.
How to interpret your result
Your result is a practice record, not a normative memory percentile. Rehearsal strategy, language, distraction, display timing, and repeated exposure influence span.
