Digit Span
Digit Span is a standard neuropsychological assessment (Wechsler, 2008) measuring working memory. A sequence of numbers (0–10) is read aloud by an automated voice and shown on screen one at a time. The participant repeats the sequence by tapping the numbers, either in forwards or backwards order. The game is adaptive — the sequence length changes based on whether the participant answered correctly.
ActivitySpec: lamp.digit_span
Cognitive domain: Working memory
Configuration
The game is configured through the Activities tab. Select Digit Span and choose the forward or backward variant.
Sample Instructions
"You will hear and see a sequence of numbers. After the sequence ends, tap the numbers in the same order (forward) or reverse order (backward)."
Usage
Numbers appear on screen one at a time while being read aloud. After the sequence completes, the participant taps the numbers in the correct order. If correct, the next sequence is longer; if incorrect, the next sequence is shorter.
