Number Memory Test
Benchmark short-term digit recall capacity across increasing numerical sequences
Measure short-term memory with PULSE's forward digit-span test, which asks you to recall increasingly long number sequences in their original order.
Digit Span Working Memory
Forward digit span measures the capacity of verbal working memory to temporarily retain and reproduce an arbitrary sequence of numbers.
It reflects storage capacity in short-term memory systems without long-term encoding.
How the Assessment Operates
Sequences begin at level 1 with 3 digits and increase by one digit with each successful round.
Numbers appear on screen for a duration scaled to the digit count before clearing. Enter the sequence using the number pad or keyboard. You have 3 lives.
- Initial level starts with 3 digits
- Exposure time scaled to sequence length
- 3 lives before benchmark concludes
Scoring and Level Advancement
Correct entries advance you to longer sequences, while incorrect submissions deplete lives. Your recorded score is the highest level achieved.
Strategies and Scope
Chunking numbers into rhythmically grouped subsets can aid recall. This test is an educational benchmark, not a standardized psychometric IQ assessment.
Frequently Asked Questions
How long is each number displayed?
Exposure time scales dynamically with digit length, providing sufficient time to read each numerical string before input begins.
