Number Memory Test
You will be shown a sequence of digits. Memorize them, then type them back. Starts at 4 digits and adds one each round.
FAQ
The average person can remember 7 digits. Scores above 9 are considered above average, and remembering 12+ digits puts you in the top percentile of the population.
Practice chunking numbers into groups of 3-4, create associations or stories with the digits, and practice regularly. Working memory training like dual n-back can also help.
This test measures your digit span, a key component of short-term and working memory. It is closely related to the forward digit span subtest used in clinical neuropsychological assessments.
About this test
The number memory test measures your digit span — how many digits you can hold in short-term memory at once. This is one of the oldest and most widely used measures in cognitive psychology.
How It Works
You are shown a sequence of digits that increases by one each round. After the digits disappear, you must type them back from memory. The test ends when you make a mistake.
What Is Normal?
The average adult digit span is about 7 items, a finding first reported by psychologist George Miller in 1956. However, this varies with age, attention, and practice. Children typically have shorter spans, while trained mnemonists can recall 80+ digits.
Tips to Improve
- Chunk digits into groups (e.g., 4-8-1-9-3 becomes 48-19-3)
- Use rhythm or melody to encode sequences
- Practice regularly — digit span is trainable
- Minimize distractions during the test
