A digit span test is a widely used psychological assessment tool that measures short-term memory and working memory capacity
Watch this video to learn more about the digit span test and how it works
Tests your ability to hold and manipulate information in your mind, a crucial cognitive function for learning and problem-solving
Based on decades of cognitive psychology and neuroscience research, used in clinical and educational settings worldwide
Provides insights into your cognitive abilities and helps track improvements in memory performance over time
Regular practice can help improve working memory capacity, attention span, and overall cognitive performance
Monitor your performance improvements and compare your results with population averages
Complete a comprehensive cognitive assessment in just 5-10 minutes, anytime and anywhere
Simple rules, challenging gameplay, scientifically accurate results
A sequence of digits will appear on screen. You have 5 seconds to memorize the complete number sequence
Focus your attention and use memory techniques to retain the digit sequence in your working memory
After the countdown, type the exact number sequence you remember and submit your answer
Start with 1-digit numbers and progress through 20 increasingly challenging levels up to 20 digits
Your performance is evaluated based on accuracy and the difficulty level achieved
Level 1: 5 points, Level 2: 10 points, Level 3: 15 points... up to Level 20: 100 points
Maximum possible score: 1,050 points (all levels correct)
Backed by decades of cognitive psychology and neuroscience research
The digit span test was developed by cognitive psychologists to measure working memory capacity, one of the most important components of human intelligence and cognitive function.
Neuroimaging studies show that digit span tasks activate the prefrontal cortex, parietal cortex, and other brain regions crucial for executive function and attention.
Used in clinical psychology, educational assessment, and cognitive neuroscience research to evaluate memory deficits, track cognitive development, and study brain-behavior relationships.
Digit span tests are standardized, validated assessment tools with established reliability and validity metrics in psychological research and clinical practice.
Most adults can remember 7±2 digits, establishing the baseline for working memory capacity

The cognitive foundation behind digit span tests
Working memory is your brain's mental workspace—the system that holds and manipulates information temporarily while performing cognitive tasks. It's like your mind's RAM, actively processing and working with information in real-time.
Key Fact: The average person can hold approximately 4±1 pieces of information in working memory at once. Digit span tests measure your individual working memory capacity.
Working memory is the ability to hold and manipulate information in your mind for short periods. It's essential for reasoning, learning, and comprehension.
Working memory capacity strongly correlates with intelligence, academic performance, and problem-solving ability. It's a key predictor of cognitive success.
Working memory can be improved through targeted training. Regular practice with digit span tests and other cognitive exercises can increase your capacity.
