Processing Speed Test
A key links seven symbols to seven digits. Learn it, then type the matching digit for each symbol that appears. You have 60 seconds to complete as many as you can, so speed matters — but only correct answers count. See your score, accuracy and rating.
About the Processing Speed Test
This is a symbol-digit coding task, a classic measure of processing speed. Instead of judging whether something matches, you must retrieve a fixed symbol-to-digit rule from memory and translate it into a fast, accurate key press. The mapping never changes during the run, so any speed-up reflects fluency with the code.
Answer with the on-screen number pad or the number keys 1 to 9. A wrong digit flashes red and the symbol stays until you enter the correct one, so errors cost you time rather than ending the run. Your result is the number of correct entries in 60 seconds, with accuracy shown alongside.
About
The Processing Speed Test measures how quickly you can translate visual symbols into the correct numeric responses under a strict time limit. A key at the top of the screen pairs nine distinct symbols with the digits one through nine. During the 60-second round, symbols appear one at a time in the center of the display and you must type the matching digit as fast as possible before the next item loads.
How your result is scored
Your final score is the total number of correct symbol-to-digit entries completed within the 60-second window. Incorrect keystrokes do not subtract points but they consume time that could have been used for correct responses. A higher count indicates faster visual scanning, symbol decoding, and motor execution; a lower count simply reflects a slower pace on this specific task and is not a clinical diagnosis.
Tips to improve
- Memorize the symbol-digit key before starting so you do not need to glance up repeatedly.
- Keep your fingers on the number row or numeric keypad to minimize hand movement.
- Focus on the center symbol only; ignore peripheral distractions on the screen.
- Maintain a steady rhythm rather than rushing in bursts that cause errors.
- Practice a few short sessions daily to build automaticity in the mapping.

Frequently asked questions
- What does this test actually measure?
- It measures the speed of visual-motor integration and rapid symbol decoding over a fixed one-minute period.
- Do wrong answers lower my score?
- No, only correct entries are counted; mistakes just waste time that could have earned points.
- Can I use the numeric keypad instead of the top number row?
- Yes, either input method works as long as the digits one through nine are registered.
- Is a low score a sign of cognitive impairment?
- Not necessarily; this is a casual screening tool, not a medical diagnostic instrument.
