Test for Processing Speed (Symbol–Digit Matching)

Tasks wey match symbols with digits dey among the measures people use pass to check processing speed: how quick you fit take in wetin you see, compare am with a key, and respond. One big review of this kind test, the Symbol Digit Modalities Test, find say e reliable and sensitive enough to use as speed measure for medical research 1.

This page na our own game for the same family, with our own symbols. E no be that test, e no get any of that test's norms, and e no fit tell you anything about your health.

• One key for top pair 9 symbols with digits from 1 to 9. The key dey change every run.
• One symbol go show at a time. Tap the digit for number pad or press the key; the next symbol go show sharp-sharp. Dem dey count wrong answers.
• 6 practice symbols with feedback go come first (you fit skip dem), then 90 seconds. If you comot from the page, the run go end, because dem dey time the test.

Your score na the number of symbols wey you match correct within the time. We go also show your average time for each symbol and how many you get wrong; if you go faster, e usually mean say you fit make more mistakes. For the first few runs, you go remember more of the key and get faster, so compare your own runs when the scores don settle. For test wey measure speed alone without key, try the test for reaction time.
