Corsi Block-Tapping Test
The Corsi Block-Tapping Test assesses visual-spatial working memory. The system highlights a sequence of blocks; you tap them back in the same (forward) or reverse (backward) order. A staircase procedure adapts difficulty, and everything runs locally in your browser.
Key Features
- Forward and backward recall modes
- Adaptive staircase difficulty
- Visual-spatial span scoring
- Product-score (sum of correct sequence lengths)
- Age-norm reference (child ~4.8, adult ~5.5, elderly ~4.9)
- 100% client-side
Use Cases
- Self-check of spatial memory
- Clinical or research screening aid
- Cognitive training and tracking
How to Use
- Pick a recall mode (forward/backward)
- Watch the blocks light up in sequence
- Tap the blocks back in order
- Continue as length grows
- Read your span and product score
Practical Tips
- Minimize distractions during the task
- Backward span is harder and more sensitive
- One low run is normal; trends matter
- Use as a training tracker, not a diagnosis
FAQ
- Corsi vs digit span?
- Corsi measures visual-spatial memory (location sequences); digit span measures verbal/phonological memory (number sequences).
- Is a low score a problem?
- A single low run is usually not concerning; if it persists, consider a professional assessment.
