For information and self-reflection
This assessment is not a medical or psychological diagnosis and not a clinical screening tool. It cannot determine whether you have a medical or mental-health condition. If you are concerned about your health, please seek advice from an appropriately qualified healthcare professional.
What this measures
Digit Span is the classic verbal short-term memory task: how many digits you can reliably hold and reproduce in order, including a backwards span variant.
How it works
Digits appear at a fixed pace, then you type them back. Forward span reproduces in order; backward span reverses. Two trials per length.
How results are calculated
Your primary result is your maximum forward span (and backward span where taken), feeding the working-memory index of the IQ Estimate.
Accuracy & limitations
Attention and input method affect results. Research-grounded (Evidence B), not a clinical evaluation.
